Document Type and Number:
WIPO Patent Application WO/2021/035873
Kind Code:
A1
Abstract:
An image sensor (100) and an image acquisition system. The image sensing (100) comprises: a pixel acquisition circuit array (110) composed of a plurality of pixel acquisition circuits (112), the pixel acquisition circuits (112) being suited to monitoring light intensity changes in the field of view and entering a trigger state when the light intensity changes meet a certain condition; a boundary trigger pixel determining array (120) suited to determining a trigger pixel acquisition circuit at a boundary from amongst the pixel acquisition circuits in a trigger state; and a read-out unit (130) suited to responding to the trigger pixel acquisition circuit at a boundary and outputting address information corresponding to same.
