Abstract:
1. A single integrated circuit for providing a centered video imaging comprising: a light detector array comprising a plurality of detector cells arranged in rows and columns; means for scanning out a photocurrent at each detector cell of the light detector array to provide a video image; means for summing the photocurrent at the detector cells along each row and column in the light detector array; means for computing row and column centroids of the video image using the output of the summing means; and a sequencing means for using the row and column centroids from the computing means and the video image from the scanning means to scan out the centered video images; wherein the means for scanning is independent of the means for computing such that the light detector array does not have to be scanned out prior to computing row and column centroids, thereby increasing the frequency response of the circuit.
