DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Next, embodiments of the present invention will be explained with
reference to the accompanying drawings hereinafter.
FIG. 1(a) is a block diagram showing an example of a configuration
of a digital camera according to the present invention. The digital
camera 100 comprises an optical system 1 composed of lenses, a diaphragm
mechanism, etc., and for irradiating a reflected light reflected
from an imaging object onto a CCD 2; the CCD 2 for converting an
image pickup light supplied from the optical system 1 into an electric
signal; a signal processor 3 for processing the signal from the
CCD 2 and then outputting the signal as multi-valued (R, G, B) raster
data (image data) to a frame memory 6; a control section 4 for controlling
operations of the signal processor 3, the frame memories 6, a signal
processor 7 and a recording medium controller 8, and controlling
the image processing, the image compressing/expansion processings,
etc.; an input section 5 for inputting an instruction from the user
by the operation of the switch, etc. to provide it to the control
section 4; the signal processor 7 for converting the R, G, B raster
data on the frame memory 6 into a luminance component Y and color
difference components U, V, JPEG(Joint Photographic Experts Group)-compressing
these components, and executing the contraction processing to generate
thumbnail image; the recording medium controller 8 for receiving
the output of the signal processor 7, and executing the controls
to write JPEG-compressed image data (referred to as "JPEG image
data" hereinafter) and thumbnail image data into a predetermined
location of a built-in recording medium 9 or an extended recording
medium 10, to read respective recorded JPEG image data, etc.; the
built-in recording medium 9 for storing the JPEG image data; the
extended recording medium 10 which is attached as occasion demands;
an interface 11 employed to communicate the data with external devices;
a display section 15 composed of LED indicators, etc., for displaying
operation states of the switch and functional specifications; and
a display screen 16 composed of a liquid crystal display, etc.,
for displaying the picked-up image or the imaging object image.
The built-in recording medium 9 is composed of a 4 MB flash memory
being fixed on the inside of the camera 100. A 4 to 45 MB compact
flash (trademark of SanDisk Corporation) card is employed as the
extended recording medium 10. As the built-in recording medium 9
and the extended recording medium 10, a SRAM (Static RAM), a memory
card, a FD (floppy disk), HDD (hard disk drive), MD (mini disk),
etc. may be employed.
FIG. 1(b) shows a configuration of the control section 4. The control
section 4 is composed of a CPU 41, a RAM 42, and a ROM 43. Control
means 430 (FIG. 2) which consists of a group of programs necessary
for operation control and data processing in the digital camera
100 is stored in the ROM 43. If a group of programs constituting
a controller 430 stored in the ROM 43 are stored in the built-in
recording medium 9, the ROM 43 may be omitted.
FIG. 2 is a view showing an example of a configuration of the controller
430 stored in the ROM 43. The controller 430 is composed of a means
required for the operation control of the digital camera 100, and
an means required for the JPEG compression of the image data, storing/reading
of the JPEG image data, or the expansion of the JPEG image data.
The controller 430 comprises a control system 431, an operation
judgement section 432, internal programs 433, data management section
50, and an image insertion section 60. Although the a data management
section 50 and the image insertion section 60 are contained in the
internal programs 433 in the embodiment, they are illustrated independently
by way of explanation.
The control system 431 executes an overall operation control of
the digital camera 100, for example, control of a diaphragm motor
driver (not shown) of the optical system, operation controls of
the signal processor 3, the frame memory 6, the signal processor
7 and the recording medium controller 8, and controls of the operation
judgement section 432, the data management section 50, and the image
insertion section 60.
The operation judgement section 432 judges what operation is input
from the input section 5 in accordance with the instruction given
by the user when a desired operation or processing is selected by
the user to operate the switch, etc. provided on the digital camera
100. In response to the decision result, the operation judgement
section 432 transfers the control to the concerned program of the
internal programs 433 to the image insertion section 60, or transfers
the control to the control system 431 to execute the externally
introduced program.
The internal programs 433 are made up of programs for picking up
the images, generating the JPEG image data, and controlling LED
display at the time of picking up the image, etc., and are built
in the ROM 43. As an example of the internal program, there is a
compression program in the JPEG specification, which is necessary
for writing the JPEG image data into the built-in recording medium
9.
The image data (JPEG image data) are processed by the internal
programs 433 or a circuit equivalent thereto, and stored in the
built-in recording medium 9 or the extended recording medium 10
by the recording medium controller 8.
The data management section 50 associates with load/deletion/addition
of the picked-up image data into/from/into the recording medium
9 and load/deletion/addition of the program code introduced from
the external device, and executes data management which is equivalent
to file management being widely conducted by the computer device
such as the PC, etc. For example, there is the file management in
MS-DOS (trademark of Microsoft Corporation), etc.
The generated image data are loaded onto the recording medium 9
or the extended recording medium 10 by the recording medium controller
8. In this case, there is a necessity that the recording location
of the image data on the recording medium 9 must be managed. For
example, the data must be written into empty areas, i.e., write
enable areas when the image data are recorded, but there is a need
that the recording medium controller 8 must know which area of the
recording medium 9 is the empty areas.
For this reason, the data management section 50 is constructed
to handle a sheet of image data as the data file, provide separately
its register list, e.g., directory, and record the register list
itself in a predetermined location of the recording medium as a
file (referred to as a "data management file 51" hereinafter).
The predetermined location of the recording medium corresponds to
a predetermined block if the recording medium 9 is composed of the
flash memory, or a predetermined sector and track if the recording
medium 9 is composed of the magnetic disk.
FIGS. 3(a) and (b) show an example of the data management file
51. The data management file 51 has a management record 510 every
image data, and such management record comprises at least an image
number (or ID number) 511, a recording start position 512 and a
recording end position 513 of the image data, a pointer 514 indicating
a continuous recording start position, an associated image number
515, and a write inhibit/enable flag 516.
The image number 511 consists of a data type code and a number.
The thumbnail image data, the image data, etc. are present as the
data type, and the data type code is defined such that the thumbnail
image data are indicated by "A", the image data are indicated
by "B", or the like.
Normally the recorded address of the image is written into the
recording start position 512 and the recording end position 513.
If the recording medium 9 is composed of the flash memory, the block
number of the corresponding image data is written thereinto.
The pointer indicates a continuous recording start position which
is searched by the recording medium controller 8 when an area where
one data is to be written is smaller in size of the data and which
is separated from the area where the one data is to be written.
According to use of the pointer, the data can be logically continuously
loaded and read. In this case, if the recording end position coincides
with the end position of the loaded data, a special code, e.g.,
0000, is written into the pointer 514.
The associated image number 515 records the image number of the
corresponding thumbnail image data if the concerned data are the
image data, or the image number of the corresponding image data
if the concerned data are the thumbnail image data. In this event,
as shown in FIG. 3(a), if thumbnail image management records and
JPEG image management records correspond to each other at a fixed
distance (address distance), the associated image number 515 should
not be provided since the thumbnail image management records and
the JPEG image management records can be correlated with each other.
As for the write inhibit/enable flag 516, normally the write inhibit
code is written when the data are loaded while the write enable
code is written when the data are deleted, etc. Since the data management
section 50 checks the flag 516, then treats the data in the area
which is defined by the recording start position 512 and the recording
end position 513 and the in area which is defined by the pointer
514 as the read inhibit data, the image data can be logically deleted
in fact when the write enable flag is written into the area.
The data management section 50 is not limited to the above system.
The data management section 50 may be constructed to write several
places of data identification numbers to head positions of the thumbnail
image data and the JPEG image data, for example, A01 to An for the
thumbnail image data and B01 to Bn for the JPEG image data upon
loading the data, and then to manage recording information such
as attributes, write location, occupied areas, etc. of respective
data by searching the identification numbers from the head of the
recording medium.
As the method of changing processing sequence of the recorded image
data, there are change of physical sequence of the image data and
change of logical sequence of the image data.
As a particular example of change of physical sequence of the image
data, in the image data recorded in the order of the image numbers
A010, A020, A030, . . . , An-1, An, an example in which A011 picked
up after An is inserted after A010 will be considered. First, the
image data of the image number A020 are saved to the RAM 42, then
the image data of the image number A011 are written into the location
of the image data of the image number A020, and then the image data
of the image number A011 are canceled from the original location.
Then, the image data of the image number A030 are saved into the
RAM 42, and then the image data of the image number A020 which have
already been saved in the RAM 42 are written into the location of
the image data of the image number A030. A11 image data are replaced
in the order of the image numbers A010, A011, A020, A030, . . .
, An-1, An by repeating the above operations.
The above method is suitable for sequence change in the record
which has a relatively small data size, e.g., sorting of a key record
of the index file. It is difficult to save the image data having
the large data size into the RAM 42 having a small capacity. Since
save and load must be repeated in unit of block, or the like to
write one image data, the image data must be saved into a working
memory, e.g., for which the frame memory 6 is substituted, in practice.
However, since the number of writing times of the flash memory cannot
be assured only about ten thousand times if the flash memory is
employed as the built-in recording medium 9, it is impossible to
say that it is not desired to repeat load/cancel operations many
times in changing the sequence of the image.
Next, the change of logical sequence of the image data will be
explained with reference to FIGS. 3(a) and (b). The change of the
processing sequence of the image data can be achieved by replacing
the management record 510 registered in the data management file
51 in unit of the image number. Since the number of the management
records which can be registered in the data management file 51 is
small and also the size of the management record 510 which consists
of the image number 511, the recording start position 512, the recording
end position 513, and addition information (514 to 516) is small,
the sequence of the management record 510 can be updated physically
by loading the data management file 51 itself into the RAM 42. Also,
the data management file 51 can be stored in the built-in memory
medium 9 and the extended memory medium 10 respectively, but it
may be stored in a rewritable memory such as EEPROM, etc.
FIGS. 4(a) and (b) are views showing the logical change of the
processing sequence.
FIG. 4(a) shows the data management file 51 before the processing
sequence is changed. FIG. 4(b) shows the data management file 51
after the processing sequence has been changed. For convenience
of explanation, only the image number 511, the recording start position
512, and the recording end position 513 are illustrated for five
image data.
In FIG. 4(a), it is assumed that the image of the image number
A05 is inserted as an inserted image between A01 and A02. To begin
with, the management records 510 of A02 to A04 are saved in the
RAM 42, and then the management record 510 of A05 is loaded in the
location A02. Then, when the management records 510 of A02 to A04
are loaded in the locations A03 to A05, the order of the management
records 510 is A01, A05, A02, A03, A04 and thus A05 is inserted
between A01 and A02. After this, as shown in FIG. 4(b), the image
numbers are updated in ascending order like A01, A02, A03, A04,
and A05. As a result, the image insertion can be achieved logically
without the change of the physical location of the image data which
are stored in the recording medium.
If the flash memory is employed as the built-in recording medium
9, the block number is written into the recording start position
512, the recording end position 513, and the pointer 514, and the
data management file 51 itself is loaded in unit of block. Therefore,
the new data management file 51 being changed as above can be implemented
by saving all the data management files 51 in the RAM 42 once, and
then canceling the contents of the block of the flash memory on
which the data management files 51 has been written.
Other Embodiments of the Present Invention
Another example of data management by the data management section
50 is shown in FIGS. 5(a) to (c). The image data are managed by
a file name management file 71, a file management table 72, and
an image data 73. The file name management file 71 consists of a
file name 711 for indicating each image data 731, and a pointer
712 for indicating a location in which the image data 731 is recorded.
The above pointer 712, and a recording start location 721 and a
recording end location 722 in which the image data 731 is recorded
are stored in the file management table 72. In order to indicate
the end of the image data, a special code, e.g., "FFFFFFFF"
is written as the file name.
Another Embodiment 1
The logical change of the processing sequence of the image data
will be explained with reference to FIGS. 6(a) and (b).
The processing sequence of the image data is given in compliance
with the stored order of the file names 711 stored in the file name
management file 71. As shown in FIG. 6(a), it is assumed that the
image data A corresponds to the file name of image 001 and then
the image data B, C, D, E correspond to the file names of images
002 to 005 in sequence. At this time, the processing sequence can
be given as the processing sequence of the image data A, B, C, D,
E in compliance with the stored order of the file names 711.
Then, let us consider the case where the image data are arranged
in the processing sequence of the image data A, E, B, C, D by updating
the processing sequence of the image data. As shown in FIG. 6(b),
the image data are updated by checking the pointer 712 in the file
name management file 71. Since the pointer 712 in the file name
management file 71 is not updated, the processing sequence of the
image data is changed in the order of the image data A, E, B, C,
D.
Another Embodiment 2
Although the processing sequence of the image data is set in the
stored order of the file names 711 in the above another embodiment
1, data indicating the processing sequence will be attached to the
file name 711 per se in this another Embodiment 2.
For instance, "XXX" in the image XXX of the file name
711 is managed as the data indicating the processing sequence. In
the example shown is FIG. 6(a), since image 001 is first processed
and then images 002, . . . , image 005 are processed in order suceedingly,
the processing sequence of the image data 731 is given as the order
of the image data A, B, C, D, E.
Next, let us consider the case where the above processing sequence
is set in the order of the image data A, E, B, C, D. Since the processing
sequence of the image data is given by the sequence of the numerals
in the file names if only the file names 711 in the file name management
table 71 are updated as shown in FIG. 7, such processing sequence
of the image data can be changed on the order of the image data
A, E, B, C, D.
Another Embodiment 3
Unless the image data management table is not particularly provided,
the processing sequence can be changed by attaching information
indicating the processing sequence to a part of the image data and
then updating the information.
Embodiment 1
FIGS. 8(a) to (c) are views showing an example of a display screen
on which an inserted image and an inserted position candidate image
are displayed. FIG. 9 is a flowchart showing an example of an operation
of an image insertion section 60.
(1) Display of Inserted Image and Inserted Position Candidate Image
In step S1, first the first thumbnail image on the recording medium
as well as the image number is displayed. If the user continues
to push a button 19, the thumbnail images as well as the image numbers
are displayed continuously, as shown in FIG. 8(a). If the user pushes
a button 20, the display returns to the thumbnail image which is
precedingly displayed. If the user pushes the button 17 when the
image to be inserted is displayed, the desired inserted image and
the mountain landscape image of the image number A051 can be displayed
fixedly on the right side of the screen, as shown in FIG. 8(b).
In step S2, the first thumbnail image A001 (portrait image) is
displayed as the inserted position candidate image on the left side
of the screen. For example, if the user desires to combine the suceedingly
picked-up mountain landscape image A051 with the precedingly picked-up
mountain landscape image together and then pushes a button 19 to
search the mountain landscape image, the thumbnail images are displayed
subsequently. If the user pushes the button 20, the screen returns
to the precedingly displayed thumbnail image. If the user pushes
the button 17 when the desired mountain landscape image A020 is
displayed, the image A020 can be displayed fixedly as the inserted
position candidate image on the left side of the screen. The processing
advances to step S3.
(2) Decision of Image Insertion Position
In step S3, the inserted position deciding screen in FIG. 8(c)
is displayed to promote the user to decide that the inserted image
A051 should be inserted before the image A020 or after the image
A020. If the user pushes the button 19 to insert the inserted image
A051 before the image A020, the image A051 and the image A020 are
switched and displayed on the left side and the right side respectively.
If the user pushes the button 19 to insert the inserted image A051
after the image A020, the image A051 and the image A020 are displayed
as they are. In either case, flashing the OK mark requests the user
to confirm them. If the button 17 is pushed, an insertion flag is
set to "1" when the inserted image A051 should be inserted
before the image A020 while the insertion flag is set to "2"
when the inserted image A051 should be inserted after the image
A020, and then the processing goes to step S4.
(3) Image Insertion
In step S4, the management record 510 of the image number A051
is held by searching the data management file 51. If the flag is
"1" the management records 510 of the image number A051
and subsequent image numbers are read from the data management file
51, and then saved in the RAM 42. The management record 510 of the
image number A051 is loaded into the location of the management
record 510 of the image number A020 in the data management file
51. The management record 510 which has been saved in the RAM 42
is then read, and then written in next recording locations subsequently.
Then, the processing goes to step S6. Since the image number (associated
image number 515) of the corresponding JPEG image is written in
the thumbnail image, the sequence of the management record 510 of
the JPEG image can be similarly changed. If the insertion flag is
set to "2", step S5 is carried out.
In step S5, the management records 510 of the image number A021
following to the image number A020 and subsequent image numbers
are read from the data management file 51, and then saved in the
RAM 42. The management records 510 of the image number A051 is loaded
into the location of the management records 510 of the image number
A021 in the data management file 51, and then the management records
510 which have been saved in the RAM 42 are read and written into
the succeeding recording locations successively. Then, the processing
is shifted to step S6. In this case, the sequence of the management
records 510 of the JPEG images can be similarly changed.
In step S6, the thumbnail image management record of the data management
file 51, the image number 511 of the JPEG image management record,
and the associated image number 515 are updated in ascending order.
According to the above steps, the desired inserted image can be
logically inserted into the desired locations. Since the data recording
medium controller 8 refers to the data management file 51 in reading/loading
or deleting the image data, the image data train can be output in
accordance with the sequence of the management record 510 in the
data management file 51 at the time of display onto the liquid crystal
display 16 or output of the image data to the external device.
Embodiment 2
FIGS. 10(a) and (b) are examples of the display screen on which
only the inserted position candidate image is displayed. FIG. 11
is a flowchart showing the operation of the image insertion section
60.
(1) Display of Inserted Image and Inserted Position Candidate Image
In step S11 in FIG. 11, first the first thumbnail image on the
recording medium together with the image number is displayed. If
the user continues to push the button 19, the thumbnail images as
well as the image numbers are displayed continuously as the inserted
position candidate image, as shown in FIG. 10(a). If the user pushes
the button 20, the display returns to the precedingly displayed
thumbnail image. If the user pushes the button 17, the processing
goes to step S12.
For example, it is assumed that the image number of the desired
fish image to be inserted (not shown), e.g., A56, is stored and
then the image A56 is inserted into the location of the previously
picked-up fish image by looking for such location. If the user continues
to push the button 19, the inserted position candidate images 82,
82' are displayed, as shown in FIG. 10(a). When the images are displayed
by operating the buttons 19, 20, and then the user, if finds the
fish image, pushes the button 17. When the button 17 is pushed,
the processing goes to step S12.
(2) Decision of Image Insertion Position
In step S12, the inserted position deciding screen in FIG. 10(b)
is displayed to promote the user to decide that the stored image
A56 to be inserted should be inserted before the image A11, or between
the images A11 and A12, or after the image A12.
If the user pushes the button 19, the insertion flag is set to
"1" to insert the inserted image before the image A11.
If the user pushes the button 20, the insertion flag is set to "2"
to insert the inserted image between the images A11 and A12. If
the user pushes the button 18, the insertion flag is set to "3"
to insert the inserted image after the image A12.
(3) Image Insertion
In step S14, when the user pushes the button 19 shown in FIG. 10(c)
one time, "10" is added to the inserted image counter
and the counter value is displayed on the liquid crystal display
16. When the user pushes the button 17, the thumbnail image of the
concerned image number is displayed, and then the processing goes
to step S15. While, if the button 18 is pushed as the error, then
the counter value is set to "0" and the display returns
to the display shown in FIG. 10(c).
In step S15, the management record 510 of the image number A56
is held by searching the data management file 51. If the flag is
"1", the management records 510 of the image number A051
and subsequent image numbers are read from the data management file
51, and then saved in the RAM 42. The management record 510 of the
image number A56 is loaded into the location of the management record
510 of the image number A11 in the data management file 51. The
management record 510 which has been saved in the RAM 42 is then
read, and then written in next recording locations subsequently.
Then, the processing goes to step S18. Since the image number of
the corresponding JPEG image is written in the thumbnail image,
the sequence of the management record 510 of the JPEG image can
be similarly changed.
In step S16, if the image insertion flag is set to "2",
the management records 510 of the image number A12 and subsequent
image numbers are read from the data management file 51 and saved
in the RAM 42. The management record 510 of the image number A56
is loaded into the location of the management record 510 of the
image number A12 in the data management file 51. The management
record 510 which has been saved in the RAM 42 is then read, and
then written in next recording locations subsequently. Then, the
processing goes to step S18. The sequence of the management record
510 of the JPEG image can be similarly changed.
In step S17, if the image insertion flag is set to "3",
the management records 510 of the image number A13 and subsequent
image numbers are read from the data management file 51 and saved
in the RAM 42. The management record 510 of the image number A56
is loaded into the location of the management record 510 of the
image number A13 in the data management file 51. The management
record 510 which has been saved in the RAM 42 is then read, and
then written in next recording locations subsequently. Then, the
processing goes to step S18. The sequence of the management record
510 of the JPEG image can be similarly changed.
In step S18, the thumbnail image management record 510 of the data
management file 51, the image number 511 of the JPEG image management
record 510, and the associated image number 515 are updated in ascending
order.
The embodiments of the present invention have been explained as
above, but it is needless to say that the present invention should
not be interpreted to be limited to the above embodiments and various
variations and modifications may be adopted.
According to any digital camera or any method of changing processing
sequence of recorded image data of the present invention, the processing
sequence of the image data can be changed. Therefore, the image
data can be displayed in good order on the liquid crystal display
as associated images. The image data to be output to the external
device can also be output in good order as associated image data.
