Abstract

An imaging device includes a plurality of first pixels, each of which outputs a first pixel signal, a plurality of second pixels, each of which outputs a second pixel signal, a ramp wave generator that outputs a ramp signal that monotonously increases or monotonously decreases over time, a phase shift pulse generator that outputs first to n-th phase shift pulse signals, a first pixel latch group that latches the first to n-th phase shift pulse signals when the first pixel signal and the ramp signal have a predetermined relationship, a second pixel latch group that latches the first to n-th phase shift pulse signals when the second pixel signal and the ramp signal have the predetermined relationship, first to n-th power source lines to supply a power source and first to n-th phase shift pulse supply lines to supply the phase shift pulses.

First claim

What is claimed is:

1. An imaging device comprising:
a plurality of first pixels, each of which outputs a first pixel signal which depends on an incident physical quantity;
a plurality of second pixels, each of which outputs a second pixel signal which depends on the incident physical quantity;
a ramp wave generator that outputs a ramp signal that monotonously increases or monotonously decreases over time;
a phase shift pulse generator that outputs first to n-th phase shift…
