ABSTRACT:
A timing generator sets a 1-frame period, in which a pixel signal is read from a CCD, at a first period or a second period that is longer than the first period. The timing generator outputs specific timing signals (with optimal driving frequencies) to a vertical driver and a horizontal driver. If it is discriminated that the timing signal for a time period necessary for reading the pixel signal for one frame is output, the timing generator stops the output of the timing signal. Thereby, power saving can be achieved without deterioration of image quality, while reading of the pixel signal is being executed with an optimal driving frequency for the image-capturing element.
