Title:
SOLID-STATE IMAGING ELEMENT AND METHOD FOR DRIVING THE SAME
Document Type and Number:
Japanese Patent JP2020188360
Kind Code:
A
Abstract:
To provide a solid-state imaging element capable of performing A/D conversion of a pixel signal in a short period of time, and a method for driving the same.SOLUTION: A solid-state imaging element according to the present disclosure includes: a pixel part in which a plurality of pixels for performing photoelectric conversion are disposed in a matrix; first and second signal holding circuits that are provided so as to correspond to one pixel column formed of a plurality of pixels arrayed in a first direction, and that respectively hold a first signal and a second signal from the pixel column; a reference signal generation circuit that generates a reference signal; a first comparator that is connected to an output of the first signal holding circuit and that compares the first signal and the reference signal with each other; a second comparator that is connected to an output of the second signal holding circuit and that compares the second signal and the reference signal with each other; and a logic circuit that is connected to the respective outputs of the first and second comparators, and that outputs a computation result of an output signal from the first comparator and an output signal from the second comparator.SELECTED DRAWING: Figure 2
