    Abstract: An imager and a method for real-time, non-destructive monitoring of light incident on imager pixels during their exposure to light. Real-time or present pixel signals, which are indicative of present illumination on the pixels, are compared to a reference signal during the exposure. Adjustments, if necessary, are made to programmable parameters such as gain and/or exposure time to automatically control the imager's exposure to the light. In a preferred exemplary embodiment, only a selected number of pixels are monitored for exposure control as opposed to monitoring the entire pixel array.

    Abstract translation: 一种成像器和一种在曝光时对成像器像素入射的光进行实时,无损检测的方法。 在曝光期间将表示像素上的当前照明的实时或呈现像素信号与参考信号进行比较。 如有必要,可以对可编程参数(如增益和/或曝光时间)进行调整,以自动控制成像仪对光的曝光。 在优选示例性实施例中,与监视整个像素阵列相比,仅监视选定数量的像素以进行曝光控制。
