Image sensor, imaging system, and image sensor driving method

摘要

An image sensing apparatus (100) includes a pixel array (10) including an optical black region (02) and effective pixel region (03), and a scanning unit (30) which scans the pixel array. The scanning unit includes a first shift register (05, 08) which scans the optical black region by a shift operation, and a second shift register (06, 09) which scans the effective pixel region by a shift operation. The second shift register starts the shift operation during a first period (TP1) when the first shift register scans the optical black region, and scans a readout region serving as a partial region of the effective pixel region during a second period (TP2) following the first period.
