摘要：
A method of an image sensor circuit includes: providing an event camera comprising at least one pixel unit; using the event camera to sense at least one current pixel value of the at least one pixel unit to detect whether at least one pixel value changes; when the at least one pixel value changes, using the event camera to trigger the digital processing circuit when the digital processing circuit is in a power saving mode and transmit information of the at least one pixel value to the digital processing circuit.
