Abstract
The digital still camera 1 has CCD 33 with an electronic shutter for controlling an exposure amount, and a timing generator 34 and a vertical/horizontal driver 35 for driving CCD 33. Under control of a controlling unit 42, the timing generator 34 and a vertical/horizontal driver 35 generate an electronic shutter pulse signal once every time plural periods have come each for reading charge of one line from CCD 33. Power consumption can be reduced in controlling exposure using the electronic shutter.
