Abstract:
1. A solid-state imaging apparatus comprising: a pixel array in which a plurality of pixel units are arranged to form a plurality of rows and a plurality of columns, and a plurality of processing portions each corresponding to each of the plurality of columns of the pixel array, the plurality of pixel units comprising a first pixel unit which includes a photoelectric conversion element, and a transistor which outputs, to a first column signal line, a signal corresponding to charges generated in the photoelectric conversion element, and the plurality of processing portions comprising a first processing portion which includes a first front-side capacitor configured to hold a first signal provided through the first column signal line and having a noise component, a first back-side capacitor arranged behind the first front-side capacitor, a second front-side capacitor configured to hold a second signal provided through the first column signal line and having the noise component and a signal component corresponding to an amount of light incident on a corresponding pixel unit, a second back-side capacitor arranged behind the second front-side capacitor, a first transfer portion configured to transfer the first signal from the first front-side capacitor to the first back-side capacitor, and a second transfer portion configured to transfer the second signal from the second front-side capacitor to the second back-side capacitor, wherein, in a physical layout of the apparatus, a position of the first transfer portion in a direction parallel to the first column signal line and a position of the second transfer portion in the direction parallel to the first column signal line are different from each other.
