Digital Camera Patent

Digital camera for capturing and recording a moving image

Digital Camera Patent Abstract

Moving images can be collectively recorded in one file with ease when the moving images are repeatedly captured in the same place or situation. The digital camera which can capture a moving image and record a captured moving image in a file includes a mode setting dial which sets a single recording mode or a continuous recording mode. The captured moving image is recorded in a newly created file when the single recording mode is set by the mode setting dial, and the captured moving image is additionally recorded in an existing file in which a moving image is recorded when the continuous recording mode is set by the mode setting dial. Therefore, when the moving images are repeatedly captured, the moving images can be collectively recorded in one file with ease, and can be also jointed in captured order.

6. The digital camera according to claim 1, further comprising: a file selecting device which selects the existing file, wherein when the existing file is selected by the file selecting device, the recording device records the captured moving image additionally in the selected existing file, and when the existing file is not selected by the file selecting device, the recording device records the captured moving image additionally in an existing file in which a latest moving image is recorded.

7. The digital camera according to claim 6, further comprising: an index display instructing device which selects a plurality of files from a recording medium which stores files including the file in which the moving image is recorded in the single recording mode and the file in which the moving image is recorded in the continuous recording mode, and provides an instruction to display an index image constituted by a plurality of frames corresponding to the plurality of files; and a display controlling device which, when the index display instructing device provides the instruction to display the index image, forms the index image based on the plurality of files stored in the recording medium and displays the index image on an image monitor, and which displays a frame corresponding to the moving image recorded in the single recording mode and a frame corresponding to the moving image recorded in the continuous recording mode among the plurality of frames forming the index image with display forms thereof being different from each other.

8. The digital camera according to claim 7, wherein when the recording medium includes a file in which a still image is recorded, the display controlling device displays the frames corresponding to the moving images recorded in the single recording mode and the continuous recording mode with display forms thereof being different from a display form of the still image.

9. The digital camera according to claim 6, further comprising: a selecting device which selects an arbitrary file from a recording medium which stores the files including the file in which the moving image is recorded in the single recording mode and the file in which the moving image is recorded in the continuous recording mode; and a display controlling device which displays one frame of the moving image on an image monitor in such a manner that a display form thereof is different between when the moving image is recorded in the file selected by the selecting device in the single recording mode and when the moving image is recorded in the file selected by the selecting device in the continuous recording mode.

10. The digital camera according to claim 9, wherein when the recording medium includes a file in which a still image is recorded, the display controlling device displays the frames corresponding to the moving images recorded in the single recording mode and the continuous recording mode with display forms thereof being different from a display form of the still image.

Digital Camera Patent Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a digital camera, and more particularly to a digital camera which can capture a moving image and records a captured moving image in a file.

2. Description of the Related Art

A digital camera has been known which can capture a moving image as well as a still image, such as dsc-SX550 manufactured by SANYO Electric Co., Ltd. This camera has a function of jointing a plurality of captured moving image data.

On the other hand, a video camera which records moving images on a magnetic tape can continuously record the moving images on one magnetic tape in captured order as long as the magnetic tape is unchanged.

However, the video camera has problems of difficulty in search since various kinds of moving image data including different capturing dates, places, situations or the like are continuously recorded on one magnetic tape in captured order, and complicated capturing with magnetic tapes changed for each kind of data.

Each moving image data captured by the digital camera which can capture the moving image is recorded in a new file for each capturing, and has a thumbnail or the like for index display. Therefore, the moving image can be selected from the index displayed thumbnails and played back, but it is difficult to search a desired file from the thumbnails since a new file is created for each capturing of the moving image to thereby provide enormous number of files.

A digital camera having the function of jointing the plurality of moving images can joint and collect the plurality of files, but has a problem of complicated operation in jointing a large number of files. Generally, the moving data are desirably jointed in time order, but there is a possibility that the data are not jointed in time order because of operation errors or the like.

SUMMARY OF THE INVENTION

The present invention has been achieved in view of the above-described circumstances, and has as its object the provision of a digital camera which can collectively record moving images in one file with ease and smoothl
