摘要： An image display system comprises a display unit which includes regularly arranged red, green and blue pixel elements and which changes a displaying state of the pixel elements to display an image; a pixel data generator which generates pixel data consisting of three items of first pixel element data corresponding to red, green and blue signal levels; a pixel element data generator which converts the pixel data into several items of second pixel element data as a minimum unit data corresponding to the signal levels of respective colors; and a controller which selects any one of a first display mode on the basis of the pixel data outputted from the pixel data generator and a second display mode on the basis of the second pixel element data generated in the pixel element data generator, wherein when selecting the second display mode, the controller sets a pixel number of the pixel data generated in the pixel data generator so as to coincide with a display pixel number of the display unit.

摘要： A color conversion device and method are provided in which six hues and inter-hue areas are corrected independently, and the conversion characteristics can be changed flexibly, and which does not require a large-capacity memory. Coefficients of second-order and first-order calculation terms relating to the respective hues, first-order calculation term using comparison-result data relating to the respective inter-hue areas, and product terms based on the comparison-result data and the hue data are changed so as to change the target hue or inter-hue area, without influencing other hues or inter-hue areas.

摘要： After applying gray scale conversion to image data of three colors, six hue data are obtained, and then first comparison-result data and second-order terms each relating to one of the six hues, and second comparison-result data each relating to one of the six inter-hue areas are obtained. Matrix calculation is performed on the first comparison-result data, the second comparison-result data, and the second-order terms, using coefficients. By varying the coefficients, adjustment can be made to only the target hue or inter-hue area, without affecting other hues and inter-hue areas. Thus, the six hues and six inter-hue areas can be varied independently, and the large-capacity memory is not required. Moreover, by the use of the gray scale conversion, the effects of the non-linear characteristics of the input signals are removed.
