ABSTRACT:
In a photoelectric converting apparatus having a plurality of photosensors divided into an opening portion and a light shielding portion, a carrier eliminating structure to block the inflow of photosignals from the opening portion is provided between the photosensor in the light shielding portion and the photosensors in the opening portion. The photosensor comprises of a photoelectric converting transistor having a control electrode region to accumulate the carriers generated by the light excitation. The carrier eliminating structure has the same constitution as that of the photosensor. The potential of the control electrode region is fixed to a constant potential so as to attract the carriers from the opening portion.
