ABSTRACT:
An image sensing device allowing normal or teleconversion operation has an image sensor which includes a plurality of horizontal lines and is capable of being non-destructively read out. Area setting ciruitry is included for variably setting a reading area of the image sensor. Clock control circuitry includes a plurality of reading lines and is arranged to read out image information from the selected reading area. Reading circuitry non-destructively reads out, a plurality of times for the tele-conversion operation, the signals from the set reading area. The reading cycle corresponds to the size of the set reading area. Clearing circuitry is also included for clearing altogether the areas of the image sensor other than the set reading area.
