Abstract
An error variance circuit, wherein a reproduced error, as detected at an error detection circuit, is added to the image signal of the input signal picture element of n bits, and wherein a variance output signal is converted into a signal of m (.ltoreq.n-l) bits and outputted to a display panel, includes a clear circuit that clears error at each frame and forcibly reduces the prior error to zero thus preventing excessive noise from preceding frames and non-image duration causing flickering of picture.
