Abstract
A system controller controls a solid-state image pickup device so as to read pixels at a predetermined pixel skip-reading-out rate. During pixel skip-reading-out, the system controller adds up, for example, four pixels to acquire a value representative of a unit area for pixel skip-reading-out. A space between adjoining ones of pixels to be added up is set to, for example, a half of an inter-sample space, whereby an MTF of an image signal representing added pixels, which is attained at the sample rate, is set to 0. Consequently, an aliasing noise can be eliminated and deterioration in image quality can be prevented. Moreover, since four pixels are added up irrespective of a pixel skip-reading-out rate, a sensitivity will not vary.
