Abstract

PURPOSE: To compensate the ununiformity in sensitivity of each image sensor element and to reduce the capacity of a memory device by providing a sensitivity memory, which is operative to store in advance the sensitivity of each element of an image sensor having a plurality of elements, a plurality of compensating memories and an adding circuit.
CONSTITUTION: The compensation is accomplished by making use of the characteristics of an image sensor of silicone type. There are provided a dark signal memory 13 for storing the dark signal level of each element in advance and a sensitivity memory 15 so that the output of the dark signal memory 13 is subtracted by a subtracting circuit 14 from the output 101 which is converted in an A/D manner from a sensor output. A plurality of compensating memories 16 are addressed by the output of the sensitivity memory 15 and accessed by each bit of the output of the subtracting circuit 14. All the outputs of the compensating memory 16 are added by an adding circuit 17 so that the compensated result is produced as the sum of the weights for the respective bits from the adding circuit 17.
