Abstract

PURPOSE: To set the discrimination function to the characteristic pick up plate, by detecting the element transmitting the maximum output of characteristic pick up plate of input information for pattern recognition.
CONSTITUTION: The photo electric conversion element on specific region of the input photo electric conversion layer UO in which photo electric conversion elements are arranged in two dimension checkerboard type, corresponds to one circuit element of the first order characteristic pick up plate US1, the region corresponded on the conversion layer UO is shifted by one element and overlapped each other sequentially. The photo electric conversion elements UCX1WUCX9 of the specific region UOX of the conversion layer UO are added as positive input to the linear total sum element Σ via the gain adjustment elements RX1WRX9. Simultaneously, the average value of the outputs from all the elements of the conversion layer UO is fed to negative input of the element Σ as the suppression input VS. Further, the gain of the adjustment elements RX4WRX6 is taken large, then if lateral bar pattern is incoming, greater output is picked up from the total sum element Σ for pattern recognition.
