摘要： A method of generating a second bit map, improved in first-direction resolution, from a first bit map having a plurality of image-forming pixels arranged two-dimensionally, the method comprising a first detection step of detecting first and second edges appearing in a second direction orthogonal to a first direction in a first bit map, and the first addition step of adding at least an edge extending in the first direction, when a portion between the first and second edges permits interpolation, to between third and fourth edges on the second bit map respectively corresponding to the first and second edges so as to effect interpolation between the third and fourth edges. Since the first and second edges, if detected, permit smoothing, a look-up table is not needed, and even a long-range unevenness can be smoothed without a smoothing range being limited to a predetermined region.

摘要： There is described a method for processing an input image, so as to output a processed image. The method includes the steps of: deriving image characteristic information of a predetermined area, which includes adjacent pixels and is located in a vicinity of an image-processing object pixel other than the adjacent pixels, from information of the adjacent pixels residing in the predetermined area, both the adjacent pixels and the image-processing object pixel being included in the input image; and applying a sharpness-enhancement processing to the image-processing object pixel, based on the image characteristic information. The image characteristic information includes at least one of a sum of differential signal absolute-values between the adjacent pixels residing in the predetermined area, a variance of each signal value of the adjacent pixels residing in the predetermined area and a standard deviation of each signal value of the adjacent pixels residing in the predetermined area.

摘要： When the image data having a predetermined gradation value for each pixel is input, and the image data is searched from the initial pixel and the total of the gradation values of the pixels, including the searched pixels, becomes a predetermined threshold value or more, a dot is generated at the center of the gravity position as a quantized pixel group. In the searching, an unprocessed pixel closest to the center of gravity position, including this pixel, is selected. If there are a plurality of unprocessed pixels, selection is performed at random. For the pixel selection, a pixel closest to the center position computed from the positional coordinates may be selected, rather than the center of gravity. Also a dot may be generated at the center position of the quantized pixel group.

摘要： A parameter representing whether an effective density pixel exists in an objective image is calculated. As to each interest pixel in the objective image having one pixel neighboring a downstream side in a first direction, the interest pixel is defined as an effective density pixel when a first condition and a second condition is an effective density pixel are satisfied, and in other case, the interest pixel is defined as an ineffective density pixel. The objective image is converted to an update image on one-line reduced lines in the first direction. A parameter representing whether an effective density pixel exists in the update image is calculated. The conversion and the calculation are repeated about the update image as the objective image. When the objective image converts one line in the first direction, the number of continuous pixels of the effective density pixels spatially continuing is calculated based on each parameter.
