Abstract: 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.

Abstract: An apparatus and method for performing automatic exposure and gain control while minimizing oscillations as well as providing a good response time, for example, a lag time or a settling time of about one frame. The automatic exposure and gain controls are performed not only on the image as a whole but on a weighted region of interest. If the contrast in the image exceeds the dynamic range of the sensor array, then the image in the region of interest will improve at the expense of the remainder of the image. A region of interest is a selected subset of tiles upon which automatic exposure and gain control will be based. The tiles are defined by a grid system having grid coordinates, which are programmable. Image sensors have to receive feedback with regular updates of exposure and gain settings based on ever changing light conditions.

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.
