摘要： In a halftone module, it is judged whether or not the value nullratenull for each pixel is greater than zero (0). In other words, it is judged whether or not the eight-bit input data Iin of each pixel is around a half of the relative density value for a small dot of a corresponding color. If the eight-bit input data Iin of the subject pixel is near to a half of the relative density value for a small dot, noise is added to the threshold values Ta, Tb, and Tc. The noise-added threshold values Tanull, Tbnull, and Tcnull are used in the comparing process.

摘要： An apparatus to control color registration and image density and a method of calculating a color registration error. The apparatus includes registration marks formed on a transfer belt such that each of the registration marks includes a scan direction component and a slanting direction component at an angle with respect to both the scan direction and the cross-scan direction. The apparatus further includes image density marks formed on the transfer belt, having predetermined image densities, and a registration and image density sensor provided above the registration marks and the image density marks to radiate beams onto the registration marks and the image density marks. The sensor receives beams reflected from the registration marks and the image density marks to produce detection signals, and obtains registration information and image density information from the detection signals. Accordingly, X-offset, Y-offset, printing width error, and skew can be simultaneously compensated for using a single apparatus.

摘要： Color processing architecture and algorithms (CPAA) for color laser printers process and handle incoming RGB image data effectively to achieve high performance, high quality image printing with low memory requirements. CPAA supports a new data structure for faster raster operation processing (ROP) for color laser printers. The CPAA architecture advantageously improves the flow of data through the processing pipeline to provide high speed at higher resolutions, e.g., at 600 and 1200 dpi. An advance quantizer using multilevel dithering flexibly reduces bits to support fast ROP and to enable fast conversion to CMYK data with only a simple look-up table (LUT) operation by a color matching module, while an adaptive filter maintains high image quality.

摘要： In conventional image processing techniques, although a certain kind of image adjustment provides a desired effect on an image, it may cause an undesired side effect thereon, resulting in an unsatisfactory result of adjustment. On a computer serving as the nucleus of image processing, a region applicable to image processing is specified at a step, an object pixel is moved for judging whether or not it belongs to the specified region at the subsequent steps, and then a specified image processing operation is carried out if the object pixel is judged to belong to the specified region. Therefore, adjustment of image data in a certain region does not have an adverse effect on image data in other regions, making it possible to realize satisfactory adjustment in an entire image with ease. Further, on the computer, chromaticity nullx-ynull of each pixel is calculated at a step, and statistical calculation is performed at the subsequent steps if a value of chromaticity thus calculated is in a possible chromaticity range. After completion of statistical calculation on all the pixels, an average value is determined at the subsequent step, and a degree of each color adjustment is calculated while taking account of the number of pixels of interest at the subsequent step. In this manner, accurate statistical calculation is performed on color pixels to be adjusted independently of brightness, and a degree of each color adjustment is regulated by taking account of the number of pixels of interest, thereby making it possible to carry out optimum color adjustment processing without giving an adverse effect on colors of surrounding pixels.

摘要： There is disclosed an image processing apparatus for generating an address based on a difference (MAXnullMIN) between a maximum value MAX and a minimum value MIN among signals CMY indicating three primary colors of a color image for each pixel, and generating a black ink signal based on data read from a lookup table in which the data is read from the generated address, so that a black ink strength is independently set with respect to density and chroma of the image. Moreover, the lookup table with the black ink signal and an undercolor signal stored therein has a storage capacity of a number obtained by totaling a number at which the difference (MAXnullMIN) between the maximum value MAX and the minimum value MIN is an integral multiple of a predetermined value and a number at which the difference is other than the integral multiple and the maximum value MAX is equal to a maximum value of a defined region. Thereby, all combinations of the maximum value MAX and minimum value MIN are linearly interpolated without disposing any storage region.
