Abstract: An operational unit determines, for subfield(s) other than a last subfield of a plurality of subfields constituting a single frame period, based on a difference determined by a data comparison unit, exceeded display data for setting the transmittance of each pixel to a value exceeding a target transmittance corresponding to image data supplied anew. The operational unit also determines, for the last subfield of the single frame period, based on the difference determined by the data comparison unit, target display data for setting the transmittance of each pixel to the target transmittance. An overshoot operation or operations are performed within the single frame period, and each pixel is set to the transmittance corresponding to the image data. This makes it possible to avoid trails occurring in moving image display and enhance the appearance of moving image display with no increase in frame rate.

Abstract: A color image processing apparatus comprises: a reading device to read color image data of a color original image; a discriminating circuit to discriminate color tones of a plurality of areas of the color original image; a correction circuit to perform the color tone correction every area for the color image data which is output from the reading device on the basis of a discrimination output of the discriminating circuit or on the basis of an output of the reading device; and a generating circuit to generate signals corresponding to the plurality of areas. With this apparatus, by discriminating the color tones of a plurality of areas, the color tones of the areas are accurately corrected and a good copy image can be obtained. The correction data for a color film of a plurality of frames of different color tones can be made by a single reading operation.

Abstract: An image amending method for amending a signal indicative of an image which was photoelectrically converted comprises: classifying pixels which constitute a digital image into extraordinary pixels which need to be amended and ordinary pixels which do not need to be amended; setting an attention pixel; when the attention pixel is an extraordinary pixel, amending the data thereof by setting data of a peripheral ordinary pixel (other than pixels adjacent at the positions adjacent to the attention pixel in the upper, lower, left, and right directions) as amendment data for the extraordinary attention pixel; and, preferably, limiting a range of the peripheral pixels which are substituted for the extraordinary attention pixel. When no ordinary pixel exists in this range, in the amending step, the data of a previously amended peripheral pixel is set as the data of the attention pixel. With this method, a person without much experience can easily satisfactorily amend the image.
