Suppressing a fall in sensitivity upon shooting without causing similar effect as a pixel defect in spite of being able to perform focal point detection. When a gate electrode 67 is high, pinned photodiodes 41, 42 are electrically connected with each other. At this moment, a lower area of the gate electrode 67 has a photoelectric conversion function. On the other hand, when the gate electrode 67 is low, pinned photodiodes 41, 42 are electrically separated with each other. At this moment, the lower area of the gate electrode 67 does not have any photoelectric conversion function. |
