Abstract:
In an image pickup apparatus including a plurality of pixels arranged a matrix of rows and columns, a correction unit performs a correction process based on an electric signal output via a first switch element of a particular pixel and a correction electric signal output via a second switch element of the particular pixel. A correction image signal based on the correction electric signal output via the second switch element is acquired in a period that partially overlaps in time a period in which an image signal based on the electric signal output via the first switch element is acquired. When the electric signal associated with the image signal is output for the particular pixel, the second switch element of the particular pixel is controlled to be in an on-state over a period during which the first switch element of the particular pixel is in an off-state.
