ABSTRACT:
An image information processor for a liquid crystal display by a digital driver is intended to provide image display near to a source image by making continuous-tone image display by pseudo representations. The image information processor generates L-bit image display data based on P-bit source image data, L being less than P. Added to source image data of a picture element of the Nth frame (where N is a natural number of 2 or greater) is error data corresponding to the picture element of the (N-1)th frame at the same position as the picture element of the Nth frame. The high-order L bits of the P-bit data resulting from the addition are used as image display data of the picture element of the Nth frame and at least one bit of the remaining low-order bit data is held as error data of the picture element of the Nth frame. Thus, error data of a picture element of one frame is added to the same picture element of the next frame, thereby lessening the brightness difference between both the picture elements and smoothing a time change in brightness.
