Image sensing apparatus and control method for same, and information processing apparatus, printing apparatus, and print data generation method, using correlation information recorded as attribute information of image data of frame

A control method for an image sensing apparatus capable of sensing a moving image, said control method comprising:

• an image sensing step of sensing an image and acquiring image data with an image sensing unit;
• and
• a recording step of recording on a removable recording medium (a) a moving image formed with a plurality of frames of the image data acquired in said image sensing step, and (b) correlation information indicating a correlation between the image data of a frame newly acquired in said image sensing step and the image data of a frame sensed immediately before the newly acquired frame,
• wherein, in the recording step, the correlation information is recorded on the removable recording medium, together with the moving image and on a frame-by-frame basis, as attribute information of the image data of the frame at the time of sensing a moving image,
• wherein the correlation information is used to determine which of plural frames should be synthesized together to form a still frame for printing, and
• wherein frames lacking correlation are not synthesized.
