Abstract
One embodiment relates to a multi-imager video camera that includes a plurality of imagers, a plurality of image flow processors, a multi-imager video processor, a plurality of exposure control circuits, and a statistics circuit. Each imager includes a sensor array that is configured to capture image frames, and each image flow processor is configured to receive and process the image frames captured from at least one of said imagers. The multi-imager video processor is configured to receive the processed image frames from the plurality of image flow processors. The statistics circuit is configured to determine an auto exposure level based on the captured image frames from a single imager. The multi-image video processor is further configured to receive said auto exposure level and transmit said auto exposure level to all other imagers of the plurality of imagers. Other embodiments and features are also disclosed.
