Solid-state image pickup device and image pickup apparatus

An image capture device comprising a solid-state image sensor and an optical system that makes light incident on the solid-state image sensor, wherein the solid-state image sensor comprises:

• a semiconductor layer having first and second surfaces, the second surface being opposite to the first surface;
• a plurality of photosensitive cells, which are arranged two-dimensionally in the semiconductor layer between the first and second surfaces thereof;
• a first array of micro condenser lenses, which are arranged on the same side as the first surface in order to focus incoming light onto a first group of photosensitive cells that are included in those photosensitive cells;
• and
• a second array of micro condenser lenses, which are arranged on the same side as the second surface in order to focus incoming light onto a second group of photosensitive cells that are also included in those photosensitive cells but that are different from the first group of photosensitive cells, and
• wherein the optical system makes light that has come from a subject incident on the first and second arrays.
