ABSTRACT:
An image pickup apparatus comprises: first and second areas for converting an incident light to charges; a recombining electrode for allowing a part of the charges in the second area to be recombined with majority carriers; and a control circuit for allowing the charges to be respectively stored in the first and second areas and also making the recombining electrode operative, and for controlling the first and second areas and the recombinating electrode in such a manner that there is a relation of A.sub.INT <D.sub.INT between an amount A.sub.INT of charges stored in the first area and an amount D.sub.INT of residual charges which are not recombined in the second area. Thus, an interlacing effect and a strong blooming-prevention effect are obtained. Further, the image pickup apparatus has a suppressing device for suppressing a part of added information of the charges in the first and second areas, so that the dynamic range of luminance can be widened.
