Digital camera with downsampling and zoom processing and method of controlling operation of same

摘要

A CCD is driven so as to output a video signal at a rate of one line out of four up to an enlargement ratio of 2x. If the enlargement ratio of 2x is surpassed, the CCD is controlled so as to output a video signal at a rate of one line out of two. Since resolution of the image represented by the video signal output from the CCD is raised, an image having a comparatively high resolution is obtained even when the image is enlarged by an electronic zoom function.
