摘要：
Certain embodiments provide a solid-state image pickup device including a first pixel, a second pixel, and an output circuit. The first pixel has a first photodiode and a first microlens that is formed above the first photodiode. The second pixel has a second photodiode and a second microlens which is formed above the second photodiode and is smaller than the first microlens. Further, the second pixel has a sensitivity of 1/n times of the first pixel and has a photoelectric conversion period of n times of the first pixel. The output circuit outputs a differential signal of a difference between a first detection signal based on a charge amount of the first signal charge and a second detection signal based on a charge amount of the second signal charge.
