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.
Claims4
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 pulse signals which differ from one another in phase in response to an input pulse signal;
- 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 and that includes an alignment in a row of a plurality of first latches each of which includes an alignment in column of first to n-th first latch units;
- 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 and that includes an alignment in a row of a plurality of second latches each of which includes an alignment in column of first to n-th second latch units;
- 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 pulse signals,
- wherein the i-th power source line is to supply power to the i-th first latch units and the i-th second latch units,
- wherein the i-th phase shift pulse supply line is to supply the i-th phase shift pulse signal to the i-th first latch units and the j-th second latch units, and
- wherein n is a natural number greater than 1, i is a natural number equal to or greater than 1 and equal to or smaller than n, and j is a natural number equal to or greater than 1 and equal to or smaller than n, and different from i.
