1. A solid-state imaging apparatus comprising:
a first light-shielded pixel region including two or more rows of pixels each including a photoelectric converter which is shielded from light;
an aperture pixel region including pixels each including a photoelectric converter which is not shielded from light; and
a control unit configured to perform control in such a manner that a charge accumulation period for the pixels in the first light-shielded pixel region is longer than a charge accumulation period for the pixels in the aperture pixel region and time to read signals from the pixels in a first row of the first light-shielded pixel region is different from time to read signals from the pixels in a second row of the first light-shielded pixel region,
wherein a start time of the charge accumulation period for the pixels in the first row differs from a start time of the charge accumulation period for the pixels in the second row.
