阅读说明：本技术 具有自适应曝光时间的像素传感器 (Pixel sensor with adaptive exposure time ) 是由 安德鲁·塞缪尔·贝尔科维奇 陈松 刘新桥 于 2019-08-20 设计创作，主要内容包括：在一个示例中,一种方法包括：将第一光电二极管暴露于入射光以产生第一电荷；将第二光电二极管暴露于入射光以产生第二电荷；由第一电荷感测单元将第一电荷转换成第一电压；由第二电荷感测单元将第二电荷转换成第二电压；控制ADC,以基于第一电压来检测第一电荷的量达到饱和阈值,并且当第一电荷的量达到饱和阈值时测量饱和时间；基于检测到第一电荷的量达到饱和阈值,停止将第一光电二极管和第二光电二极管暴露于入射光；以及控制ADC,以基于第二电压来测量在曝光结束之前由第二光电二极管产生的第二电荷的量。(In one example, a method comprises: exposing a first photodiode to incident light to generate a first charge; exposing the second photodiode to incident light to generate a second charge; converting the first charge into a first voltage by a first charge sensing unit; converting the second charge into a second voltage by a second charge sensing unit; controlling the ADC to detect that the amount of the first charge reaches a saturation threshold based on the first voltage, and to measure a saturation time when the amount of the first charge reaches the saturation threshold; based on detecting that the amount of the first charge reaches a saturation threshold, ceasing exposure of the first photodiode and the second photodiode to incident light; and controlling the ADC to measure an amount of the second electric charge generated by the second photodiode before the end of the exposure based on the second voltage.)
