| 发明名称 | Image capturing apparatus and control method therefor | ||
| 摘要 | An image capturing apparatus having pixels is provided. Each pixel includes a photoelectric conversion unit including a charge accumulation region, an output unit configured to output a signal based on a potential of a node electrically connected to the charge accumulation region, and a connection unit configured to electrically connect a capacitance to the node. The charge accumulation region includes a first portion and a second portion. Charge is configured to be first accumulated in the first portion, and, after the first portion is saturated, be accumulated in the second portion. The output unit is configured to output a first signal based on the potential of the node before the capacitance is connected thereto, and, then a second signal based on the potential of the node after the capacitance is connected thereto. | ||

| 主权项 | 1. An image capturing apparatus having a plurality of pixels, wherein each of the plurality of pixels comprises: a photoelectric conversion unit including a charge accumulation region; an output unit configured to output a signal based on a potential of a node electrically connected to the charge accumulation region; a connection unit configured to electrically connect a capacitance to the node; and a first holding unit and a second holding unit; wherein the first holding unit is configured to hold a first signal output based on the potential of the node before the capacitance is connected thereto, and wherein the second holding unit is configured to hold a second signal output based on the potential of the node after the capacitance is connected thereto. | ||
