Title:
EVS PIXEL WORKING METHOD AND RELATED APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/201907
Kind Code:
A1
Abstract:
Provided in the present application are an EVS pixel working method and a related apparatus. The method comprises: recording, at a first moment, an output voltage generated by an EVS pixel in response to the intensity of incident light, so as to obtain a first voltage; taking the first voltage as a reference voltage, and performing integration on the output voltage within a preset integration duration after the first moment, so as to obtain a voltage change value; and comparing the voltage change value with a preset voltage threshold value range, and outputting an event signal when the voltage change value exceeds the voltage threshold value range. By means of the implementation of the solution of the present application, integration is performed, within a certain duration, on a voltage change value generated by an EVS pixel in response to a change in light intensity, such that the voltage change value is amplified, and therefore can more clearly express whether a voltage change is positively increased or negatively decreased, thereby effectively ensuring the accuracy of an event signal which is output by an EVS.
