Document Type and Number:
WIPO Patent Application WO/2019/181110
Kind Code:
A1
Abstract:
The present invention improves image quality while maintaining a readout speed in a solid-state imaging element provided with an analog/digital converter. This solid-state imaging element is provided with a lamp signal supply unit, a comparator, and a counter. In this solid state imaging element, the lamp signal supply unit supplies a lamp signal of a frequency corresponding to the signal level of a pixel signal. The comparator compares the lamp signal and the pixel signal, and outputs a comparison result. The counter counts a count value over a period until the comparison result is inverted.
