    Abstract: A dual sensor imaging system is described for visible and infrared light. One example includes a first image sensor to detect the luminance of a scene, a second image sensor to detect the visible light chrominance of the scene and to detect an infrared image of the scene, and an image processor to receive the luminance from the first image sensor and the chrominance from the second sensor to generate a visible light image of the scene, the image processor to further receive the infrared image from the second image sensor and to extract the infrared image from the visible light chrominance of the scene.

    Abstract: A light sensor is described with correlated double sampling. In one example a first storage element is coupled to a photodetector to collect free electrons as an accumulated charge. A transfer switch is coupled to the first storage element. A second storage element is coupled to the first storage element through the transfer switch to collect the accumulated charge from the first storage element when the transfer switch is open. A sense circuit measures the charge on the second storage element before the accumulated charge is collected from the first storage element as a reference charge and measures the charge on the second storage element after the accumulated charge is collected from the first storage element as a read charge. The sensed charge is determined by comparing the reference charge to the read charge.

    Abstract translation: 用相关的双重采样描述光传感器。 在一个示例中,第一存储元件耦合到光电检测器以收集作为累积电荷的自由电子。 转移开关耦合到第一存储元件。 第二存储元件通过转换开关耦合到第一存储元件,以在转换开关打开时收集来自第一存储元件的累积电荷。 在从第一存储元件收集累积的电荷作为参考电荷之前,感测电路测量第二存储元件上的电荷,并且在从第一存储元件收集累积电荷作为读取电荷之后测量第二存储元件上的电荷 。 通过将参考电荷与读取的电荷进行比较来确定所感测的电荷。
