A method for auto-exposure control in a multi-imager system is disclosed. The method comprises using an auto exposure control circuit of a first imager to set exposure control parameters based on a target brightness; and selectively adjusting the target brightness based on difference in brightness between the images from the first imager and images from other imagers in the system.

One embodiment relates to a method of outputting multiple views from a networked camera. Each imager of an array of imagers in the camera captures image frames and transmits the captured image frames to an associated image flow processor. Each image flow processor processes the captured image frames and transmits the processed image frames to a multi-imager video processor. An updating of parameters for said processing by each image flow processor is performed on a frame-by-frame basis. Another embodiment relates to a video camera including a plurality of imagers, a plurality of image flow processors, a multi-imager video processor, and a plurality of update queues. Other embodiments and features are also disclosed.

One embodiment relates to a synchronized multiple imager system includes a plurality of imagers. One or more respective sensors are coupled to the imagers. The sensors output a vertical raster stream representative of pixel data from pixel columns, thereby generating a plurality of vertical raster streams. A clock circuit synchronizes the sensors to sense selected columns in the imagers and to output the vertical raster streams from the selected columns. A processor circuit stitches seam vertical raster streams from adjacent pairs of imagers. The synchronized multiple imager system may further include a plurality of input buffers coupled to respective sensors. The clock circuit may include input flip-flops configured to acquire the vertical raster stream from respective imagers in accordance with an imager bus clock. The clock circuit may further include asynchronous FIFOs to de-skew the vertical raster streams. Other embodiments, aspects and features are also disclosed.
