摘要： Based on an input operation by an operator, a line drawing processor sets a designated region and sets identification points in the designated region to generate first and second identification data, each data representing a colored pixel cluster linked to each of the identification points. The line drawing processor further extracts at least one closed region that is not colored in the second identification data and makes a comparison in area between each closed region and the pixel cluster colored in the second identification data to determine whether the closed region requires coloring or not. For line drawing data, the line drawing processor then applies the same color to the pixel cluster identified in the second identification data and the closed region determined to require coloring.

摘要： Plate-image-inspection RIP data CD2, CD3 are prepared using the same RIP processing conditions from two print image data prepared in different steps of the prepress process, and inspection results are obtained by comparing these data CD2, CD3. Plate-image-inspection RIP data CD2, CD3 can be prepared in several methods: (1) a method for RIP processing respective non-RIP data using standard RIP processing conditions; (2) a method for respectively converting two RIP data to standard RIP processing conditions; and (3) a method for converting one of two RIP data such that it conforms to the RIP processing conditions of the other.

摘要： A method of performing a descreening process with high accuracy by separating a first region from which a gradation area is to be derived and a second region from which a monotone area is to be derived from each other in a screened image with high accuracy is provided. Halftone dot positions and halftone cells are specified at an output resolution level based on the angle dependence of a distribution obtained by counting recorder grids constituting each halftone dot in one direction. By extracting edges of halftone dots and counting them in one direction, the position of deformed halftone dots positioned on a boundary between first regions having different gradation levels is detected at the output resolution level, whereby the position of picture-originated pixels is specified with high accuracy. Based on a positional relationship between inconsistent recorder grids caused when bringing the picture-originated pixels and SPM data into correspondence with each other which is derived from the result of the specification of the position of the picture-originated pixels, a preset separation mask is corrected with high accuracy at a recorder grid level. The use of the separation mask achieves high-accuracy separation between the first and second regions. Consequently, more precise correspondence between the picture-originated pixels and the SPM data improves the accuracy of the descreening process.

摘要： A hash value generation section at a plate making site, which is a first site, generates a hash value based on edit layout data. A reference image data output section outputs reference image data to a folder named after the hash value. The reference image data is transmitted from the plate making site to a press plate site, which is a second site, while being kept contained in the folder. A hash value generation section at the press plate site generates a hash value based on the edit layout data transmitted from the plate making site. Based on the hash value, a plate inspection process section retrieves a folder containing reference image data that is to be used for a plate inspection process.

摘要： An image processing apparatus of the present invention compares a first proof image and a second proof image, to detect a different portion, and displays the different portion on a display part. Therefore, an operator can check the second proof image after subjected to an automatic trap processing in respect to only the different portion between the first proof image and the second proof image, and perform a trap edit processing as needed. Hence, the trap edit processing to the second proof image can be performed efficiently, and the operator's workload can be reduced.

摘要： A conversion computation section acquires the original color density value of a single process color in a given image region and the original color density value of a spot color from raster data, and acquires a pseudocolor conversion rate for conversion from the spot color to the process color from spot color information. Then, the conversion computation section calculates a proof color density value Hi of each process color on a pixel-by-pixel basis in each image region by using a conversion computation expressed by Hi=Pi+s·Gi−Pi·s·Gi where Pi (i=C, M, Y or K) is the original color density value of the single process color, s is the original color density value of the spot color, and Gi is the pseudocolor conversion rate for conversion from the spot color to the process color. The proof color density value reflects a change in gradation of the process color and a change in gradation of the spot color without the saturation of the color density.

摘要： Average density values are calculated from a pixel group which contains an objective pixel and neighboring pixels around the objective pixel, and an image filter to use for processing of the objective pixel is specified in accordance with the average density values. Using the specified image filter, filter computation is performed on a main signal which represents the density of the objective pixel, whereby an output signal is generated. The main signal which represents the objective pixel is smoothed out in an area which is larger than the size of halftone dots. In accordance with the average density values, a reference value is acquired. A set of weighting factors is selected based on the reference value, thereby determining an effective size of the image filter. The determined effective size is large in a density range where moires are noticeable. A predetermined filter computation portion executes computation based on the respective weighting factors of the image filter which has the determined effective size, to thereby generate a filtered signal. Such processing makes excellent suppression of a degraded image quality and removal of the moires possible, without deteriorating an edge of the image.

摘要： An image reader using CCD line sensors which effects color correction of three color difference signals resulting from reading of a color original by the CCD line sensors. This image reader employs a plurality of color correction characteristics for enlarging the color difference signals in regions where the color difference signals are large, and limiting enlargement ratios of the color difference signals in regions where the color difference signals are small. A color correction characteristic is selected manually or in accordance with the luminance level of each pixel. Noises appearing in shadow portions are reduced by the color correction based on the limited enlargement ratios of the color difference signals effected in the regions where the color difference signals are small.
