Image processing circuit

Abstract

The present invention provides an image processing circuit capable of properly determining whether or not image data is a static image or a moving image and performing overdrive processing thereon. The image processing circuit includes a quantization unit (quantization/threshold-value proximity determination circuit) for quantizing image data input to a liquid crystal display with a predetermined threshold value and outputting the quantized data, a threshold-value proximity determination unit (quantization/threshold-value proximity determination circuit) for determining whether or not the image data is proximal to the threshold value and outputting threshold-value proximity determination data, a moving-image/static-image determination unit (moving-image/static-image determination circuit) for determining whether or not the image data of a current frame is a static image or a moving image, on the basis of the quantized data and the threshold-value proximity determination data of the current frame and the quantized data and the threshold-value proximity determination data of the previous frame, and an overdrive processing unit (LUT, moving-image/static-image processing circuit) for outputting the image data which has been subjected to overdrive processing if the moving-image/static-image determination unit determines that the image data is a moving image.
