Abstract

A technique is presented, which consists of a computer program and ancillary instruments: (1) to adjust displacement of images taken by two or three image sensors and (2) to calibrate relationship between incident light intensity and corresponding digital output signal simultaneously. The pixel-based displacement adjustment is made by corresponding a pixel of one image sensor with four pixels adjacent to that point on another sensor. The weighted average of outputs for the four pixels are then multiplied by a coefficient calculated from a pixel-based sensitivity calibration.
