Title:
PHOTODETECTION ELEMENT AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/080226
Kind Code:
A1
Abstract:
The present invention reduces the impact of interference on a gradation signal or an event signal. This photodetection element has a pixel array unit, a row control unit and an overlap prediction row detection unit. The pixel array unit has a plurality of pixels which are arranged in a two-dimensional matrix and equipped with: an event signal generation unit for detecting a unidirectional change in the brightness of incident light as an event, and generating an event signal, which is a signal based on the detected event; and a gradation signal generation unit for generating a gradation signal, which is a signal which corresponds to the brightness of the incident light. The row control unit performs: a brightness signal generation control for sequentially performing, at a timing which is offset by row, a control for generating a gradation signal by jointly outputting a control signal to the gradation signal generation units of the pixels arranged in a row of the pixel array unit, and a control for reading out the gradation signals; and a control for detecting an event by outputting a control signal to an event signal generation unit and a control for reading out the event signal. The overlap prediction row detection unit detects an overlap prediction row, which is a row where an overlap of the intervals for gradation signal generation and event detection is predicted to occur.
