摘要： The combination patterns of emissions and non-emissions from the n-th sub-field to the m-th sub-field (where m and n are integers smaller than the total number of sub-fields, and m is greater than n) for a first pixel, a second pixel, a third pixel, and a fourth pixel that are vertically and horizontally adjacent in each of the areas in a display panel are different from one another. Among the first pixel to the fourth pixel vertically and horizontally adjacent in each area of the display panel, the grayscale value displayed by each of the first pixel and the second pixel arranged in one diagonal positions is lower than the average of the grayscale values displayed by the first pixel to the fourth pixel, while the grayscale value displayed by each of the third pixel and the fourth pixel arranged in the other diagonal positions is higher than the average of the grayscale values displayed by the first pixel to the fourth pixel.

摘要： In an image display apparatus, a video signal is divided for each field into a plurality of sub-fields, each of which is weighted according to the duration of time or number of pulses. The plurality of sub-fields are temporally superimposed for display, so that a grayscale representation is provided. A video signal for the current field is delayed by one field, and output as a video signal for the previous field. Based on the video signal for the current field and the video signal for the previous field, a luminance gradient of an image is detected. A difference between the video signal for the current field and the video signal for the previous field is calculated. Based on the calculated difference and the detected gradient, the amount of motion of the image is calculated by a detecting circuit. Based on the calculated amount of motion of the image, dynamic false contours are reduced by an image data processing circuit.

摘要： Provided are an apparatus, a method, and a program for processing an image which reduces crosstalk and achieves high image quality. The method includes obtaining a differential signal by subtracting one input image signal of an object to be processed from another input image signal; applying a predetermined correction coefficient to the differential signal; determining, for each pixel, whether the differential signal is a negative value; selectively outputting, for each pixel, the differential signal, to which the predetermined correction coefficient is applied, as a correction signal based on a result of the determining; and correcting, for each pixel, the one input image signal based on the one input image signal and the correction signal that is selectively output if the differential signal is the negative value.
