摘要： An image processing apparatus specifies pixels other than a white pixel which are included in a window, the window including a target pixel and pixels in the vicinity of the target pixel in a scanned image. Thereafter, the image processing apparatus averages color values of the specified pixels other than the white pixel, and then determines whether the target pixel is a color pixel based on a color value obtained by the averaging.

摘要： In an image processing apparatus having a first reading unit to read a front-face image of an original which is conveyed and a second reading unit to read a back-face image of the original which is conveyed, image processing parameters for eliminating the back-face image which is projected as a show-through image to the front-face image of the original which is displayed to a displaying unit are input. An image process according to each of the input image processing parameters is executed to image data of the front-face. The image data displayed to the displaying unit is switched to the image-processed image data of the front-face.

摘要： The present invention aims to eliminate a ground color of an original from image data generated by a reading unit. To achieve this, a user sets elimination levels of a plurality of color components for each of the plurality of color components while confirming the image data. Then, a process of eliminating the ground color of the original from the image data is performed based on a setting by the user.

摘要： An image processing apparatus having a reading device to read an image from a sheet includes one or more controllers to perform operations. One image is read from one sheet by using the reading device. Edge detection processing is executed on the one image. At least one pair of edges is determined from among a plurality of edges based on information of the plurality of edges detected in the edge detection processing and size information of the one sheet.

摘要： An image processing apparatus which performs image processing for print processing, including: a pseudo halftone processing unit configured to perform pseudo halftone processing by dithering with respect to an input image, and generate a halftone image constituted by plural dots, and a threshold matrix holding unit configured to hold a threshold matrix used for the pseudo halftone processing, wherein in the threshold matrix, thresholds are arranged such that the halftone image has a density region in which dots to be formed depending on a density of the input image are not rotational symmetric on a 90° basis, and orientations of the dots differ from each other in the density region.

摘要： An unnatural color change which occurs when combining trapping and spatial filter processing is suppressed. When image data is input, it is determined whether to perform trapping at the position of the pixel of interest of the input image data, and trapping is performed for the input image data. In addition, spatial filter processing is performed for the pixel of interest of the input data, an output of the trapping and that of the filter processing are weighted, and image data to be output is calculated.

摘要： An information processing apparatus, in accordance with rising density in an extreme density range, determines a threshold for setting each pixel of a threshold matrix so as to consecutively grow an isolated dot corresponding to a halftone dot in a low density range to a first dot size for each submatrix, sets, when the size of isolated dots in a predetermined number of submatrices is grown to the first dot size, an intermediate position between the isolated dots in the predetermined number of submatrices; and determines, for each of one or more submatrices including a set intermediate position, a threshold to set for each pixel of the threshold matrix so that an isolated dot is consecutively grown until a second dot size smaller than the first dot size.
