摘要： An image reader utilizing a CCD line sensor (8) which involves no possibility of any stripe pattern (output irregularity) being produced with respect to dots output from the CCD line sensor (8) even if there is any characteristic error between outputs of odd n-th and even n-th elements of the CCD line sensor (8). Data of the odd n-th elements and data of the even n-th elements are supplied to an averaging circuit (52). Where the absolute value of the difference in data between odd n-th and even n-th elements is greater than a predetermined threshold value, a decision circuit outputs a select signal of H level. Where the absolute value of the difference is smaller than the threshold value, the decision circuit (56) outputs a select signal of L level. A selector (58) selects the output of each odd n-th element or even n-th element as a read output in case that the select signal is of H level. If the select signal is of L level, a mean value of the outputs of the two elements is selected as a read output. Thus, it is possible to prevent any stripe pattern occurrence due to output irregularity without detriment to the sharpness of original reading.

摘要： A sharpness conversion part is provided in a print inspection apparatus and performs an average-masking operation to weaken a sharpness of object image data to be inspected and that of reference image data. After that, a differential value between these data is acquired. With this operation, an inspection for printing is performed by using image data of which the difference is distinguishable by human's visual property, not considering an invisible differential value which is caused by pixel displacement in subpixel order, and it is therefore possible to efficiently obtain a print inspection result with an accuracy almost as high as that by visual inspection. Thus, a print inspection apparatus can be provided, which is capable of correctly extracting difference to be detected by visual check.

摘要： Input CAD data and run-length data obtained by performing a RIP process on the input CAD data are acquired. A predetermined conversion process is performed on at least one of the input CAD data and the run-length data to make the data formats of both data comparable and then both data are compared with each other to detect an area having a difference as a defect area in the run-length data. This provides a technique to detect a defect in the run-length data to be used for drawing of a figure before the execution of drawing with a simple structure.

摘要： Multi-level gradation representation data D2 obtained by representing line drawing data D1 with a multi-level gradation is acquired, and cores are extracted from a line drawing. Further, a closed region surrounded by a core and smaller than a predetermined reference is selected. Then, the barycentric point of the selected closed region is determined, and a plurality of adjacent points adjacent to the barycentric point on the basis of a predetermined distance are defined. Thereafter, by reference to the multi-level gradation representation data D2, gradation values corresponding to the barycentric point and each of the adjacent points are acquired and compared with each other. Further, an adjacent point having the closest gradation value to the gradation value corresponding to the barycentric point is selected. Then, a boundary line lying between a closed region including the barycentric point and a closed region including the selected adjacent point is deleted.

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： A printing machine provided allows even unskilled operators to perform ink and water supply control according to the contents of an image. While a reference image to be printed is segmented into a plurality of regions similar in contents, image data is obtained from printed matter and a color difference between the reference image and a print image is calculated. Ink and water (I/W) supplies are determined based on regional color difference data obtained by summing the color differences for each region. At this time, by adding correction of the regional color difference data based on the characteristics of each region and the contents of the image, and correction of the I/W supplies based on external factors and variables, even unskilled operators can perform rapid I/W supply control based on the contents of the image.
