1. An image capturing apparatus, comprising:
a plurality of pixels, each pixel including a photoelectric conversion unit configured to generate charge in response to incident light and accumulate the charge, an accumulation unit configured to accumulate the charge, an amplifier unit configured to output a signal based on the charge, a first transfer switch configured to transfer the charge to the accumulation unit from the photoelectric conversion unit, and a second transfer switch configured to transfer the charge to the amplifier unit from the accumulation unit; and an output line to which signals from the plurality of pixels are output, wherein at a first time point, the photoelectric conversion units of the plurality of pixels start accumulation of the charge, the first transfer switches of the plurality of pixels are kept OFF from the first time point to a second time point, and the photoelectric conversion units of the plurality of pixels accumulate charge generated in a first period from the first time point to the second time point, in a second period from the second time point to a third time, the accumulation units of the plurality of pixels accumulate charge generated by the photoelectric conversion units in the first period, and charge generated by the photoelectric conversion units in the second period, at the third time, the first transfer switches of the plurality of pixels are controlled from ON to OFF, and saturation charge quantity A1 of the photoelectric conversion unit, saturation charge quantity A2 of the accumulation unit, the first period P1, and the second period P2 satisfy the following relationship:P1-0.5×P1(P1+P2)≤A1A2≤P1+0.5×P2(P1+P2). |
