Abstract
An image capturing apparatus includes a first chip and a second chip which are laminated together. The first chip includes effective pixels disposed in a first row across a plurality of columns, and an optical black pixel disposed in the first row. The second chip includes an AD conversion unit configured to perform an AD conversion on a signal output from the optical black pixel. The AD conversion unit includes a part overlapping, as seen in plan view, with the optical black pixel.

An image capturing apparatus comprising:
- a first chip;
- and
- a second chip laminated on the first chip,
- the first chip including effective pixels disposed in a first row across a plurality of columns, and an optical black pixel disposed in the first row,
- the second chip including an AD conversion unit configured to perform AD conversion on a signal output from the optical black pixel,
- the AD conversion unit including a part overlapping, as seen in plan view, with the optical black pixel.
A circuit chip for being laminated on a pixel chip including effective pixels disposed in a first row across a plurality of columns, and an optical black pixel disposed in the first row, the circuit chip comprising:
- an AD conversion unit configured to perform an AD conversion on a signal output from the optical black pixel;
- and
- a connection unit for receiving a signal output from the optical black pixel, the connection unit connected to the pixel chip, the connection unit disposed at a location overlapping, as seen in pan view, with the optical black pixel.
