Title:
SOLID-STATE IMAGING APPARATUS, METHOD OF DRIVING THE SAME, AND ELECTRONIC DEVICE
Document Type and Number:
Japanese Patent JP2019054303
Kind Code:
A
Abstract:
To provide a solid-state imaging apparatus capable of suppressing an increase in circuit area and processing time, preventing deterioration of AD conversion accuracy, realizing a broad dynamic range, and realizing high image quality, a method of driving the same, and an electronic device.SOLUTION: A solid-state imaging apparatus 10 is capable of expanding a dynamic range by combining a plurality of readout signals. A column signal processing unit includes: an ADC 410; and a comparison and selection unit 430 which compares a level of an input node [Y] to which a readout signal read out from a pixel is input with a preset reference voltage [V20] and selects an input state to the input node [Y] of the readout signal read from the pixel according to the comparison result.SELECTED DRAWING: Figure 11
