Fehlervarianzschaltung zur Verbesserung eines Bildsignals
摘要
A circuit has the reproduced error as detected at an error detect circuit (35) added to the image signal of the input signal picture element of n bits, and further has the variance output signal converted into a signal of m (</=n-1) bits to output on the display panel. The error detect circuit (35) has a clear circuit (42) that clears the error at every frame. This reduces to zero the prior error for every frame thus preventing excessive noise from preceding frames and non-image duration to avoid flickering of picture. <IMAGE>
