Patent ID: 8144999

Claim:
An image capturing apparatus having an image sensor and a processor, for capturing a moving image using the image sensor, wherein the processor is programmed to control a determining unit to determine an image frame to be used as a reference image frame in resolution conversion of the moving image captured by the image sensor, from a plurality of image frames constituting the moving image; a file generating unit to generate a reference image data file from the reference image frame determined by the determining unit; an encoding unit to reduce the resolution of the plurality of image frames and generate an encoded moving image data file from the image frames having a reduced resolution; an information generating unit to generate information specifying the reference image frame; a list generating unit to generate a list associating the information generated by the information generating unit specifying the reference image frame with information specifying the reference image data file; a first recording control unit to store the reference image data file, the encoded moving image data file, and the list in a first storage unit; and an accumulation unit to accumulate information related to the reference image frame, wherein if the newly-determined image frame is found in the plurality of image frames, the determining unit is further controlled to determine whether a similar image frame has already been used as a reference image frame, with reference to the accumulation unit, and if it is determined by the determining unit that a similar image frame has already been used as a reference image frame, the list generating unit is further controlled to associate, in the list, information specifying a reference image data file generated from the similar image frame with information specifying the newly-determined image frame.
