摘要： The inventive image processing apparatus takes steps of 1) dividing an image to be processed into numerals of blocks; 2) determining whether a block is a color block or not; 3) determining whether the image is a color image or not based on the rate of color blocks to the entire blocks. Thereby, valid color pixel rate can be obtained at blocks belonging to a color region even though an image is almost monochrome but partially colored. Accordingly, the inventive image processing apparatus can appropriately determine whether the image is a color image or not.

摘要： In an image processor which converts color image data to image data of cyan, magenta, yellow and black necessary for forming an image, a black character edge is discriminated in R, G, B image data. The edge component in a black character area is deleted by narrowing on image data of cyan, magenta and yellow. Further, in a black character area, K data is replaced with maximum density data in the R, G, B data, and edge emphasis is performed on the substituted data. Then, reproducibility of a thin line portion in a character is improved largely.

摘要： It is intended to provide an image forming apparatus and image forming method capable of partial magnification corrections on various partial variations of magnification as well as constant and uniform positional shift regardless of any sections. A modulated image clock of a reference color (black) is generated from a clock generated at an image clock generating section 23 and an address is generated at an address generating circuit 36 basing on the modulated image clock. Output sections 30 for respective colors other than the reference color read out correction coefficients from correction coefficient memories 15 of respective colors following the address generated. Frequency modulator circuits 31 modulate image clocks in accordance with correction coefficients. PWM 33 outputs a driving pulse to a laser driver 6 basing on modulated image clocks synchronized with a reference signal 40 by synchronizer circuits 32 and inputted image data.

摘要： In order to improve character edge reproducibility in reproducing a color document image, a boundary between a character and a background is detected in color image data. Further, if the detected edge exists at the side of a character, it is decided as a true edge, and the image data are subjected to edge emphasis. Then, when an image is reproduced, undesirable partial whitening in characters in the image can be prevented.

摘要： When a monochromatic image is reproduced, a user can select desired mixing coefficients of red, green and blue in order to control gradation data for the reproduction of a monochromatic image as well as a monochromatic reproduction color. When a document is automatically determined not to be a color document, the mixing coefficients of red, green and blue are changed according to the type of the document. If a monochromatic copy mode is selected, the mixing coefficients can be set manually. Preferably, in order to help a user to select mixing coefficients, a plurality of images of monochromatic colors of various mixing coefficients of red, green and blue can be printed on a single sheet of paper.
