Abstract
Provided are an imaging element and an electronic device capable of suppressing fluctuation of a black level. The imaging element includes a pixel array unit in which a plurality of pixels including a photoelectric conversion element is arranged in a matrix, the pixel array unit including a plurality of first pixels that perform normal imaging, a second pixel capable of acquiring black-level information, a first control line that controls charge transfer of the plurality of first pixels, and a second control line that is different from the first control line and controls charge transfer of the second pixel.
Claims18
An imaging element, comprising:
- a pixel array unit that comprises:
- a plurality of pixels, wherein
- each of the plurality of pixels includes a respective photoelectric conversion element, and
- the plurality of pixels includes:
- a first plurality of pixels configured to perform a normal imaging process;
- and
- a second plurality of pixels configured to:
- perform the normal imaging process in a first mode;
- acquire black level information in a second mode;
- and
- switch between the first mode and the second mode;
- a first control line configured to control charge transfer of a set of pixels of the first plurality of pixels;
- and
- a second control line configured to:
- control charge transfer of a set of pixels of the second plurality of pixels;
- and
- control the switch between the first mode and the second mode, wherein
- the second control line is different from the first control line,
- the second control line is connected to the first control line through a first switching element, and
- the second control line and the set of pixels of the first plurality of pixels are associated with a same row of the pixel array unit.
