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.

Multi-imager video camera with frame-by-frame view switching

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.

Multi-imager video camera with automatic exposure control

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.

Synchronized multiple imager system and method

A synchronized multiple imager system includes a plurality of imagers having pixels arranged in rows and columns. The pixels generate pixel data responsive to light directed onto the imagers. One or more respective sensors are coupled to the imagers. The sensors sense the pixel data from the columns and output a vertical raster stream representative of the pixel data in the 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 is configured to receive the vertical raster streams from the imagers and to process the vertical raster streams to generate a plurality of stitched raster streams. The processor circuit stitches seam vertical raster streams from adjacent pairs of imagers.
