Abstract
In a moving image correcting circuit for a display unit wherein a motion vector detecting portion detects inter-frame motion vectors and a moving image correcting position corrects the display positions of subfields for pixels in blocks, based on the detection values, the picture quality is protected from being degraded by preventing the output of an erroneous motion vector due to noise in, or fluctuation of, the input image signal or else preventing the erroneous motion vector, even if output from the motion vector detecting portion, from entering the moving image correcting portion.
