ABSTRACT:
An image sensing device is provided with a switching circuit for a selection between a field reading mode and a frame reading mode in reading signals formed at picture elements of an image sensor; and an overflow control circuit for controlling and changing the overflow level of each of the picture elements from one level over to another in response to the selecting action of the switching circuit. The device is arranged to store, at an EEPROM, data relative to the overflow levels of each of the picture elements differently set for the field and frame reading modes.
