IPC: G09G5/00
Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To correct an error by predicting growth of a pixel caused depending on a black/white boundary of adjacent pixels in the error spread system. SOLUTION: A video correction circuit 13 applies correction to an input gray video signal to generate an interpolation sub pixel value by the input error spread system and gives the value to a binarization circuit 17. The binarization circuit 17 outputs a binarized cell based on a threshold level. An error calculation 11 subtracts a black or white reference value from the interpolation sub pixel value depending on the black/white level of the executed pixel value and gives the result to a coefficient matrix circuit 15 as an error. The coefficient matrix circuit 15 divides the error into components in horizontal and vertical directions and gives them as correction data to the video correction circuit 13, where error spread is conducted.  A pixel growing compensation circuit 21 calculates a apparent deviation in a gray level based on the growth of the black pixel into an adjacent white pixel and generates an error component to compensate it.
