Abstract
Provided is an imaging device configured to sequentially perform AD conversion for A signals of pixels of the first row, A signals of pixels of the second row, A+B signals of the pixels of the first row, and A+B signals of the pixels of the second row.
Claims21
An imaging device comprising:
- multiple pixels having multiple photoelectric conversion units;
- an AD conversion unit;
- and
- a control unit,
- wherein each of the multiple pixels outputs a first signal based on signals of only some of the multiple photoelectric conversion units and a second signal based on signals of the multiple photoelectric conversion units,
- a photoelectric conversion period of the photoelectric conversion units corresponding to the first signal and a photoelectric conversion period of the photoelectric conversion units corresponding to the second signal at least partially overlap with each other,
- the multiple pixels include a first pixel and a second pixel,
- the control unit
- causes the AD conversion unit to perform AD conversion for converting the first signal output from the first pixel into a digital signal during a first period,
- causes the AD conversion unit to perform AD conversion for converting the first signal output from the second pixel into a digital signal before AD conversion for converting the second signal output from the first pixel into a digital signal during a second period after the first period,
- causes the AD conversion unit to perform the AD conversion for converting the second signal output from the first pixel into the digital signal during a third period after the second period, and
- causes the AD conversion unit to perform AD conversion for converting the second signal output from the second pixel into a digital signal during a fourth period after the third period.
