Claims19
An imaging apparatus comprising:
- a first chip including
- a plurality of first pixels each including a color filter of a first color and arranged in a plurality of rows and a plurality of columns, and
- a plurality of second pixels each including a color filter of a second color that is a different color from the first color, the plurality of second pixels being arranged in a plurality of rows and a plurality of columns;
- a second chip including a first analog-to-digital (AD) conversion unit and a second AD conversion unit;
- a first signal line to which the plurality of first pixels arranged in a first column among the plurality of columns is connected;
- a second signal line to which the plurality of second pixels arranged in a second column among the plurality of columns is connected;
- a third signal line to which the plurality of first pixels arranged in a third column among the plurality of columns is connected;
- and
- a fourth signal line to which the plurality of second pixels arranged in a fourth column among the plurality of columns is connected,
- wherein the first signal line and the third signal line are connected to the first AD conversion unit, and
- wherein the second signal line and the fourth signal line are connected to the second AD conversion unit.
An imaging apparatus comprising:
