Abstract
An imaging device according to an embodiment of the present disclosure includes: a plurality of current sources including first group current sources and second group current sources; and a control unit that controls driving of the first group current sources to generate a first-phase ramp voltage and controls driving of the first group current sources and at least one current source of the second group current sources to generate a second-phase ramp voltage.
Claims5
An imaging device comprising:
- a plurality of current sources including first group current sources and second group current sources;
- and
- a control unit that controls driving of the first group current sources to generate a first-phase ramp voltage and controls driving of the first group current sources and at least one current source of the second group current sources to generate a second-phase ramp voltage.
An imaging system comprising:
- a plurality of current sources including first group current sources and second group current sources;
