Power Efficient Image Sensing Apparatus, Method of Operating the Same and Eye/Gaze Tracking System

摘要

An image sensing apparatus has a light sensitive area and a control unit. The light sensitive area registers image data in response to an incoming amount of light, and is operable in an active mode wherein image data can be read out there from as well as in a standby mode wherein image data cannot be read out. The control unit produces a control signal setting the light sensitive area to operate in the active mode and the standby mode respectively in a cyclic manner during an operation period, which preferably encompasses multiple data frame read-outs of image data from the light sensitive area.
