  • Patent number: 6947082
    Abstract: A system controller controls a solid-state image sensor, and performs read-out at a predetermined subsampling ratio. In the event that the size of the image-taking area and the subsampling ratio do not agree, the system controller executes image size conversion processing with a digital processing unit, and converts the image size to an image size corresponding to a request from a peripheral device unit. Also, the system controller performs changing of the image-taking area following ending of the reading out from the solid-state image sensor, thereby obtaining normal frame signals. Accordingly, even in the event that zooming is performed by changing the subsampling ratio, zooming operations can be performed with an arbitrary zooming ratio, and reading out of the image-taking information is made to be suitable.
