Image-sensing apparatus

Abstract

An image-sensing apparatus has: an optical zoom control portion varying the size of the subject image on the source images by optical zooming; a particular subject detection portion detecting the position and size of a particular subject on the source images based on the image data of the source images; a narrow-angle image extraction portion setting a narrow-angle image including the particular subject to set the position and size of the narrow-angle image on image; a wide-angle image extraction portion extracting a wide-angle image that includes the narrow-angle image; a resolution enhancement processing portion cutting out a plurality of narrow-angle images according to a setting in the narrow-angle image extraction portion, to generate a narrow-angle high-resolution image having a number of pixels greater than the number of pixels of the narrow-angle image. The optical zoom control portion controls the factor of the optical zooming such that the ratio of the reference number of pixels to the number of pixels of the narrow-angle image approaches the factor of enlargement by the resolution enhancement processing portion.
