Abstract

PURPOSE: To increase the yield rate of manufacture of pick up element, by enabling to use the pick up elements having abnormal bits, through the memorization of abnormal bit signal of self-scanning type pick up elements and through the correction of the signal related to the adjacent bit signal before and after it.
CONSTITUTION: The abnormal bit signal among the output signals of a self-scanning type pick up element 3 is judged with the window type comparator 4, and this signal location is stored in the shift register 5 having the same bit number as the element 3 via the selector circuit 6. On the other hand, the output signal of the element 3 is binalized with the comparator 7 fed, and it is fed to the output selector circfuit 8 to which the output signal of the register 5 is fed, normal bit signal among the output signal of the comparator 7 is outputted as it is, and the abnormal bit signal is judged from the bit signal before and after it while being corrected. That is, the circuit 8 consists of the one bit shift registers 9,10, gate 11, inverter 12, and OR circuit 13, and based on the bit signal before and after, the abnormal bit signal can be corrected.
