Abstract

PURPOSE: To obtain the brightness information of the adjacent picture elements to be made use of for the pattern identification by providing the line detector cell adjacently to the photoelectric cells arrayed into a matrix in the optical sensor to be used to the 2-dimentional correlator and then by connecting between the detector cells via the line detector gate.
CONSTITUTION: Conductors S1, S2 ... of the photoelectric cell group are set at H-level for period TO; the depletion layer is formed under each electrode Si; and the optical image is projected to produce the charge proportional to the brightness of the picture element. Then conductor RDi is precharged for line transfer period T1, and at the same time the depletion layer is formed. And RDi is set at H-level to open line detector gate 11b, 12b and so on. As a result, the storage charge of the depletion layer under electrode 11, 12 ... enters the depletion layer under electrode 11a, 12a ... of the line detector cell. Conductor RTi is set at L-level for line detection period T2 with line detector gate closed, and the electrode potential in the line direction is used as the average value. Accordingly, output conductor RDO obtains the potential sum of each conductor RDi to be used as the average value in each line direction of the picture element of the optical image, thus obtaining the correlation function for the pattern identification.
