摘要： A monochromatic image of which the number of gradation levels (for example, 1024 levels) is greater than that (for example, 256) of a monochromatic image viably handled by an operating system (OS) (13) is converted into a color image which is then received by the OS (13). The color image to be handled by the OS (13) is embraced by the number of available colors (for example, 16,777,216) and can thus be released out directly. The color image released from the OS (13) is then converted into a monochromatic image of which the number of gradation levels (for example, 1021 or 1024) is greater than that (for example, 256) of a monochromatic image viably handled by the OS (13) before displayed. Accordingly, the monochromatic image can be displayed at multiple gradation levels which exceed the gradation limit of any conventional operating system without drastically modifying the hardware or software.

摘要： A liquid crystal display 200 comprises a 1024-to-1021 gray scale conversion calculator 1 for converting an image data A(1024) of 1024 gray levels (=10 bits) into an image data Y(1021) of 1021 gray levels, an adjusting four-level sample storage 22 and a random number generator circuit 3 for randomly selecting and releasing on the frame-by-frame basis a group of the adjusting four gray levels &Dgr;1p to &Dgr;4p, &Dgr;1q to &Dgr;4q, and &Dgr;1r to &Dgr;4r which is determined by the least two bits Y(1021—d2) of the image data Y(1021) of 1021 gray levels at each of segments (p,q,r) of one pixel, an adder 23 for summing the upper eight bits Y(102113 d8) of the image data Y(1021) of 1021 gray levels and one group of the adjusting four gray levels to have three sets of image data of 256 gray levels D1p to D4p, D1q to D4q, and D1r to D4r which are then released in a sequence, and a 256 gray scale three-segment monochrome liquid crystal display panel 24. As the result, the apparatus needs no gray scale conversion table and can be minimized in the overall cost. Also, the image of which the number of gray levels is greater than that of a display panel can speciously be reproduced with explicitness.

摘要： An original monochrome image recorded with an FPD (flat panel detector) which comprises an array, m rows and n columns, of pixels is reduced and converted into a display image which comprises an array, q rows and (3*n*q/m) columns, of pixels before the display image is transferred to a monochrome liquid crystal display equipped with a monochrome LCD which comprises an array, q rows and P columns, of pixels, where m, n, q, and P are natural numbers and m≦n, q q are given. The monochrome liquid crystal display drives the three sub pixels of each pixel independently aligned along the row of the monochrome LCD to display the display image of the pixels in q rows and (3*n*q/m) columns.
