摘要： A method for color correction in the process for reproducing a picture in which color separation picture signals obtained by photoelectrically scanning an original picture are converted into picture signals which correspond to four printing color inks including a black ink therein to produce respective reproduction pictures for plate making corresponding to each of the color inks. A picture signal which corresponds to a black ink is produced according to gray color components obtained from B, G and R signals of the original picture, and according to chromatic color components obtained by subtracting neutral color components from said B, G and R signals. Color separation picture signals corresponding to other color inks, and deficiency in reproduction density of the black ink to be used in a black print is corrected by said other three color inks.

摘要： In forming a sharpness emphasis signal, accidental errors produced in digital processing of the image data of pixels in a matrix are cancelled by using look-up table memories to suppress the appearance of corresponding noises onto reproduction images. The invention further provides for use of a reduced number of bits in processing the data and particularly in processing sums of products used in the process, by providing for products to have substantially the same number of bits as the factors of the product.

摘要： The method allows the isolation of a certain portion of an original color picture having a color which corresponds to a reference color in a photoelectrical picture reproducing process. The colors of the original picture as well as the reference color are identified by using a color plane which is divided up into incremental areas. Since the computation process is simplified, the color isolation process can be accomplished at the same time as the original picture is photoelectrically scanned.
