When a high resolution mode is required, first switches 22 are closed so as to ground the enclosure regions 13 and second switches 23 are opened so as to float gate electrodes 15. Carriers generated in the vicinity of the enclosure regions are attracted and absorbed by the junction potential of the enclosure regions. Thus, no carriers flow into adjacent photodiodes.
