A dark current correction apparatus eliminates a dark current signal component or components from an output signal of an imaging device having an array of pixels. The apparatus includes an A/D converter for digitizing the output signal, and a memory for storing level data of the digitized signal while exposure of the imaging device is controlled to be at a zero level or a uniformly illuminated level, according to whether dark current correction or white current correction, respectively, is to be performed. A dark current correction signal former generates a dark current correction signal or signals from data read out from the memory. The dark current correction signal or signals are applied to a correction circuit which processes an output signal produced by the imaging device during normal imaging operation in accordance with the correction signal or signals in order to eliminate the dark current signal component or components from that output signal.
