Abstract

An image playback apparatus includes: a moving image processing unit configured to generate playback-oriented moving image data from moving image data as a playback target, among moving image data recorded on a recording device; a display controller configured to play back, on a display device, the playback-oriented moving image data generated by the moving image processing unit; a release instruction input unit configured to receive input of a release signal during playback of the playback-oriented moving image data; a still image generation unit configured to generate, from the moving image data, still image data that correspond to a playback image being played back on the display device at a time of input of the release signal; and a recording controller configured to record, on the recording device, the still image data generated by the still image generation unit, in association with the moving image data.

First claim

What is claimed is:

1. An image playback apparatus comprising:
a data input unit into which moving image data as a playback target, among moving image data recorded on a recording device, is input;
a moving image processing unit configured to generate playback-oriented moving image data from the moving image data input from the data input unit;
a display controller configured to play back, on a display device, the playback-oriented moving image data generated by the moving image processing unit;
a release instruction input unit configured to receive input of a release signal during playback of the playback-oriented moving image data;
a still image generation unit configured to generate, from the moving image data, still image data that correspond to a playback image being played back on the display device at a time of input of the release signal; and
a recording controller configured to:
record, on the recording device, the still image data generated by the still image generation unit, in association with the moving image data; and
record input information of a release signal in association with the moving image data when the release signal is input during recording of the moving image data, wherein

the display controller is configured to:
display, on the display device, playback position information that indicates a playback position of an image being played back on the display device among a bundle of the moving image data linearly arranged in time series; and
display, on the playback position information, a first mark that indicates an input timing of the release signal input during playback of the moving image data, and a second mark that has a different display mode from the display mode of the first mark and that indicates an input timing of the release signal based on the input information recorded in association with the moving image data.

2. The image playback apparatus according to claim 1 ,
wherein the moving image data are a series of image data generated by an imaging unit at a distal end of an endoscope during endoscopic examination, and the moving image data are image data recorded, on the recording device, associated with input information of a release signal input during the endoscopic examination.

3. The image playback apparatus according to claim 1 ,
wherein the recording controller is configured to record the moving image data onto the recording device in a state where the moving image data are divided into chapters at an input timing of the release signal.

4. The image playback apparatus according to claim 3 ,
wherein input information of the release signal is one of identification information of each of the divided chapters and time information indicating the input timing of the release signal.

5. The image playback apparatus according to claim 1 ,
wherein the recording controller is configured to record the moving image data, the input information of the release signal, and the still image data generated by the still image generation unit, in a single moving image file format.

6. The image playback apparatus according to claim 1 ,
wherein the recording controller is configured to record the moving image data, the input information of the release signal, and the still image data generated by the still image generation unit, in separate files.

7. The image playback apparatus according to claim 1 ,
wherein the display controller is configured to display, on the display device, a moving image selection screen for selecting moving image data as a playback target among a plurality of moving image data recorded on the recording device, and the moving image selection screen includes a representative image of each of the moving image data, the still image data associated with each of the moving image data, and the playback position information that indicates one of the first mark and the second mark, each of the first and second marks indicating the input timing of the release signal.

8. A non-transitory computer-readable recording medium recording an image playback program for causing an image playback apparatus for playing back, on a display device, moving image data as a playback target from among moving image data recorded on a recording device to execute:
generating playback-oriented moving image data from the moving image data as the playback target;
playing back, on the display device, the generated playback-oriented moving image data;
displaying, on the display device, playback position information that indicates a playback position of an image being played back on the display device among a bundle of the moving image data linearly arranged in time series;
displaying, on the playback position information, a first mark that indicates an input timing of the release signal input during playback of the moving image data, and a second mark that has a different display mode from the display mode of the first mark and that indicates an input timing of the release signal based on the input information recorded in association with the moving image data;
receiving input of a release signal during playback of the playback-oriented moving image data;
generating, from the moving image data, still image data that correspond to a playback image being played back on the display device at a time of input of the release signal;
recording, on the recording device, the generated still image data, in association with the moving image data; and
when the release signal is input during recording of the moving image data, recording input information of a release signal in association with the moving image data.
