Title:

PROCESSING CIRCUIT AND METHOD FOR TIME-OF-FLIGHT IMAGE SENSOR

Document Type and Number:

WIPO Patent Application WO/2020/184190

Kind Code:

A1

Abstract:

A time-of-flight imaging device comprises an image sensor comprising a pixel array including a plurality of pixel circuits, respective ones of the plurality of pixel circuits including a first tap output configured to output a first tap signal, and a second tap output configured to output a second tap signal; and a signal processing circuit including a time-of-flight processing circuit configured to perform at least one logical operation on the first tap signal and the second tap signal based on a mode of the signal processing circuit, and a counter configured to output a digital signal based on an output of the time-of-flight processing circuit.
