Abstract:
1. An image shooting apparatus, comprising: an image sensing unit configured to generate image data by performing photo-electric conversion on an object image; an output unit configured to output a trigger for recording image data in a recording medium; a storage unit configured to continuously store a plurality of image data generated by the image-sensing unit in a temporary memory area at predetermined time intervals from before said output unit outputs the trigger; a selection unit configured to select image data that was shot at a track-back time that is a predetermined amount of time before the trigger output among the image data stored in the temporary memory area in response to said output unit outputting the trigger; and a recording unit configured to record image data selected by said selection unit in the recording medium, wherein said storage unit stores the plurality of image data at a first frame rate until the track-back time is a first amount of time before the trigger output and stores the plurality of image data at a second frame rate which is lower than the first frame rate until the track-back time is a second amount of time past the first amount of time, wherein there exists a plurality of factors that causes said output unit to output the trigger, said selection unit selects image data stored in the temporary memory area, of which the track back time before the trigger output and frame rate are different, on the basis of a type of the factor that causes said output unit to output the trigger.
