摘要： Any specific color (e.g., flesh-color, sky-blue and so on) is determined for its area on an original color image and corrected by the use of a matrix color correcting factor to assure a high level of reproduction of that color. Any specific color, for example flesh color, is previously extracted by pre-scanning (S1, S2). An area of the color is determined by counting its pixels included therein (S3). The determined area S of the specific color is compared with a given value C (S4). When S C, another kind of color correction is made (S9, S10). An area of each color is extracted (S9) and a suitable correction factor is selected (S10). All colors are separately corrected by using respectively selected correction factors, that assures a high-quality reproduction of the color image to be printed.

摘要： A method for forming an image in which image data defined of three original colors for forming a full color image is written in a mass of three kind of liquid crystal cells by beam light and the image is read by irradiating each liquid crystal cell with light corresponding to each of three original colors and printed out, the method including the steps of writing the image data into each liquid crystal cell by scanning beam light in a primary scanning direction and moving in a secondary scanning direction the three kind of liquid crystal cells arranged in the secondary scanning direction, and reading the image data by irradiating the liquid crystal cell with light of original colors while moving the mass of the liquid crystal cells in a direction opposite to that at the time of image writing.
