摘要
A semiconductor based image sensor having a timer that is associated with each photosite in the image sensor; and measuring the integration period of that photosite using the timer. Additionally, an imager sensor that does not require an A/D converter but instead uses a comparator circuit to determine when a predetermined threshold has been reached, thus reading as discrete amounts of stored charge which converts directly into a digital representation.
