Abstract: A controller for an image sensor includes a mode selector that receives a selection between image capture mode and data capture mode. An exposure sensor collects exposure data for a scene falling on the image sensor. A command interface sends commands to the image sensor to cause the image sensor to capture an image with a rolling reset shutter operation in which an integration interval for the image sensor is set based on the exposure data if the image capture mode is selected. The integration interval for the image sensor is set to less than two row periods, preferably close to one row period, without regard to the exposure data if the data capture mode is selected. An analog gain may be increased to as large a value as possible in data capture mode. All pixels in a row may be summed before AD conversion in data capture mode.

Abstract translation: 用于图像传感器的控制器包括接收图像拍摄模式和数据捕获模式之间的选择的模式选择器。 曝光传感器收集落在图像传感器上的场景的曝光数据。 命令界面向图像传感器发送命令，使得图像传感器利用滚动重置快门操作拍摄图像，其中如果选择了图像拍摄模式，则根据曝光数据设置图像传感器的积分间隔。 如果选择数据捕获模式，则不考虑曝光数据，图像传感器的积分间隔被设置为小于两个行周期，优选接近一个行周期。 在数据捕获模式下，模拟增益可能会增加到尽可能大的值。 在数据捕获模式下，AD转换之前可以将所有像素相加。
