1. A photoelectric conversion apparatus comprising:
a first unit pixel, and a second unit pixel, wherein the first unit pixel includes a first photoelectric conversion unit, a first transfer transistor, and a first impurity diffusion region, the second unit pixel includes a second photoelectric conversion unit, a second transfer transistor, and a second impurity diffusion region, the first transfer transistor transfers electric charges generated by the first photoelectric conversion unit to the first impurity diffusion region when the first transfer transistor is turned on during an electric charge accumulating period, the second photoelectric conversion unit accumulates generated electric charges during the electric charge accumulating period, and the second transfer transistor transfers the electric charges generated by the second photoelectric conversion unit to the second impurity diffusion region when the second transfer transistor is turned on after the electric charge accumulating period is ended, and a potential at a channel of the first transfer transistor when the first transfer transistor is on-state is higher than a potential at a channel of the second transfer transistor when the second transfer transistor is on-state. |
