摘要： It is an object of the invention to obtain an image having a better visual effect for the person who will view the visually processed image. A visual processing device 910 comprises an output portion 914 and a transformation portion 915. The output portion 914 outputs a luminance adjustment parameter P2 based on a parameter P1 expressing the ambient light. The transformation portion 915 transforms a luminance of a target pixel based on the luminance adjustment parameter P2 that is output by the output portion 914, a luminance of the target pixel to be subjected to visual processing, and a luminance of surrounding pixels positioned in an area around the target pixel.

摘要： In a case where a line noise suppression mode in which a line noise image is suppressed is enabled by a mode setting section 81, (A) a spatial filter process section 108 executes a spatial filter process with respect to a text pixel which have determined to be included in a text region by a segmentation process section 105, in which spatial filter process an edge enhancement degree of an image is smaller than that obtained when the line noise suppression mode is disabled, and (B) an output tone correction section 109 executes, with respect to the text pixel subjected to the spatial filter process, a tone correction process in which a contrast enhancement degree of an image is higher than that obtained when the line noise suppression mode is disabled.

摘要： In an X-Y conversion chart, a threshold Th is defined as Y=0, that is, the threshold Th is defined on the X axis, a range from -Th to +Th is defined as a range in which smoothing (noise elimination) processing is performed, and a range outside the range from -Th to +Th is defined as a range in which sharpening processing is performed. As shown in equations in drawings, among equations denoted by Y1 and Y2 which are expressed by two linear straight lines, intersections of both the equations Y1 and Y2 are set to the maximum value and the minimum value of an X-Y conversion equation in this case. In addition, the threshold is expressed by an intersection of Y2 and the X axis. This conversion algorithm is formed by only three factors of: a coefficient ± indicating the strength of smoothing; a coefficient ² indicating the strength of sharpening; and a threshold Th on the X axis for determining switching between the smoothing processing and the sharpening processing. Accordingly, it is possible to reduce the number of parameters for use and to keep the continuity of a smoothing input-output characteristic and a sharpening input-output characteristic even after one of the parameters is adjusted.

摘要： Restoration of edges in rasterized, continuous tone images includes selection of a pair of neighbouring pixels that exchange a restoration value to make a steeper transition from a low value on one side of a boundary between the two pixels to a high value at the other side thereof. Although any pair of neighbouring pixels is selected, this operation is only performed when four pixels in a direction perpendicular to the boundary, of which the selected pair form the two center pixels, have a monotonely increasing value. The restoration value is based on a difference value of nearest neighbouring pixels on the same side of the boundary. This avoids overshooting around edges in an image. The method is advantageous when resealing an image to a higher resolution which occurs when a low resolution image is embedded in a page that is to be printed with a high addressability printer system.

摘要： PROBLEM TO BE SOLVED: To shorten a period for transferring image data for printing from a host computer to a printer while suppressing deterioration of image quality.SOLUTION: The host computer groups pixels to generate pseudo pixels, assigns a representative value of an RGB form to each pseudo pixel, and transfers it to the printer. The host computer operates halftone processing pixels forming pseudo pixels having edge intensity selected such that amount of transfer data is equal to a predetermined value or smaller, and transfers generated dot data to the printer. The printer performs printing using the transferred dot data and representative values.
