Gray scale display device

摘要

The gradation display device contains gradient detecting circuit ( 3 ) for detecting a gradient of gradation values of pixels in an incoming image; time-varying gradation-value detecting circuit ( 4 ) for detecting changes in gradation values of the pixels with a passage of time; an image detector for detecting a magnitude and a direction of movement of the incoming image according to outputs from gradient detecting circuit ( 3 ) and time-varying gradation-value detecting circuit ( 4 ); and gradation correcting circuit ( 12 ) for correcting signals of the incoming image according to the detected magnitude and direction of the image and the weight of luminance assigned to each of the sub-fields so as to display proper image.
