Patent ID: 7039250

Claim:
An electronic camera comprising: an imaging section for generating a plurality of image data by shooting an object sequentially; a frequency dividing section for frequency-dividing each of the plurality of image data generated by said imaging section to convert the image data into transform coefficients; a coding section for dividing the transform coefficients into transform coefficients in a selection region and transform coefficients in a non-selection region, and for generating a compressed file by allocating an information amount preferentially to the selection region to the non-selection region and coding the transform coefficients in the selection region, the selection region being a region determined in advance in an image, the non-selection region being a region other than the selection region; an image evaluation section for comparing data amounts (ROI data amounts) of the coded transform coefficients in the selection region for the plurality of image data, and for selecting image data having a large ROI data amount; and a recording section for recording the compressed file of the image data selected by said image evaluation section.
