Hi, when running high frame rate, we usually do not need the ISP 3A. The gain and shutter speed are usually fixed. So maybe you can have an option to disable ISP for users like us. We need higher fps and we do NOT need ISP 3A, and ISP 3A will surely disturb our application. When we need higher fps, we need extra LED lights in a short period. And we would like to set the sensor's gain and shutter speed our own manually and NOT by the 3A algorithm. Because these extra LED lights are not always on due to the high power consumption, and we only turn LED lights on when we detect the object is passing and falls in our view area of camera. And the 3A algorithm must have to be disable in our application. Otherwise the gain and shutter speed calculated by 3A will make the images to bright when we turn the LED light on for a short period(maybe onlt 60 frames@200fps)
