Abstract:
A machine vision system to form a digital image that includes information about both (1) relative displacements of segments of an illumination profile within the digital image due to height discontinuities of corresponding illuminated portions of various surfaces in a scene, and (2) relative reflectivity of the illuminated portions of those surfaces.

Claim (Index 1):
A method useful in determining absolute image signal magnitude, the method comprising:\n forming a pixel output signal based on incoming light energy for each of a plurality of light sensitive pixel elements arranged in (N 1 \u2212N d ) rows and N 2  columns in a pixel array, wherein each of the plurality of light sensitive pixel elements includes a light sensor, and the pixel output signals represent an image signal indicative of an image of a scene; forming a reference output signal on N d  additional rows of dark pixels, each of the additional rows having N 2  dark pixels, wherein each of the dark pixels lacks a light sensor; obtaining a measurement signal of the image signal by\n a) supplying M sets of N 1  control signals to the (N 1 \u2212N d ) rows of the pixel array and the N d  additional rows of the dark pixels, where N 2  light sensitive pixel elements of each row and N 2  dark pixels of each additional row share common control signals, each of the sets of control signals is representative of a different row of a sampling matrix, the N 1  control signals in each of the M sets being in one-to-one correspondence to the total N 1  rows, (N 1 \u2212N d ) of which include light sensitive pixel elements and N d  of which include dark pixels, and \n b) for each of the M sets of control signals, summing pixel output signals to obtain current output for each of the N 2  columns; \n computing a scale factor for each of the N 2  columns based on the sampling matrix and a prior known contribution to the current output of the reference output signal formed on the dark pixels; and determining output pixel values from the measurement signal using the scale factors computed for the N 2  columns, the output pixel values comprising information of the image signal.
