Abstract: An aspect of the invention provides an image display apparatus that displays a plurality of input pixels which form input image data on a display section. In that case, each input pixel can be displayed in such a manner that display pixels having gradation values differing from the gradation value of the input pixel are combined. For example, when a pixel having a particular gradation value exists as an input pixel, the pixel is not displayed on the display section as it is being kept at the gradation value, but instead, is displayed in such a manner that a plurality of display pixels having gradation values differing from the gradation value of the input pixel are combined. As a result, the same gradation value is not displayed continuously. Therefore, this results in that the occurrence of crosstalk, which is problematical particularly in a TFD liquid-crystal panel, is reduced.

Abstract: The invention provides an easy and simple method of converting the resolution of image data, which is capable of generating the high-resolution image data without incongruity, does not make a circuit in the display device complicated and does not increase the power consumption. This invention can include a portable terminal device, such as a mobile telephone or a PDA, that processes and displays image data transmitted from the outside. Image data with a plurality of grayscales can be displayed by controlling the display state of each pixel in a display unit in accordance with grayscale control pulses corresponding to the number of grayscales. For example, when a 64 grayscale display is performed, a grayscale level is defined using sixty four grayscale control pulses. Thus, it is possible to emit light from pixels in the display unit by sixty four grayscale levels.

Abstract: The invention naturally enhances the sharpness of an image by performing appropriate sharpness processing. An image processing device receives input original image data, performs sharpness processing, and outputs correction image data. Specifically, the degree of the level change is detected from the original image data, and correction-reference-amount data, which provides a reference to determine the degree of sharpness correction, is determined based on the degree of the detected level change. Meanwhile, the relationship between correction amount by which the sharpness correction is performed and the correction reference amount is defined by a predetermined correction-amount characteristic pattern. The correction-amount calculating device calculates an adequate correction amount in accordance with the correction-amount characteristic pattern, and the sharpness processing means performs sharpness processing on the original image data in accordance with the correction amount.
