摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus which improves backlash when increasing resolution of a low-resolution image. SOLUTION: An MFP (Multi Function Peripheral) matches low-resolution binary image data received by facsimile with a dot pattern showing a jaggy. If there is any matching region, the image data is converted into multivalued image data by performing jaggy correction in which the tone of a target dot in the region is substituted with a grayscale (S11, 13). MFP also generates a region identification attribute code based on the result of matching and the tone of the input image data (S53). MFP enhances the respective resolutions of the image data after jaggy correction and the region identification attribute code (S15, S55). MFP then binarizes the image data having the enhanced resolution once again by a binarization method according to the region identification attribute code having the enhanced resolution (S17).

摘要： A method of image-resolution enhancement employing partial-template matching, including storing at least a portion of an image, and selecting from the image a window comprising a plurality of adjacent line segments having pixels, the window including a target pixel. The method also includes comparing the pixels of the window with a template for a partial match, and responsive to a partial match being found, substituting an enhancement pixel for the target pixel. By allowing a partial match for enhancement instead of requiring a 100-percent match of the prior art, the method provides image-resolution enhancement for digital-image data having noise or other errors.

摘要： PROBLEM TO BE SOLVED: To provide an image quality improving device for improving the sense of contrast. SOLUTION: A Gaussian filter 2 having a first interruption frequency extracts a low-frequency component signal of a video signal. A subtractor 3 subtracts the low-frequency component signal from the video signal to extract a high-frequency component signal. A low-pass filter 5 having a second interruption frequency higher than the first interruption frequency extracts a low band side high-frequency component signal as a signal of a low band in the high-frequency component signal. A multiplier 6 multiplies the low band side high-frequency component signal by a predetermined gain G1 to generate a corrected component signal. An adder 7 adds a corrected component signal to the video signal. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To generate vector images with a small data amount, while keeping a character in a suitable shape. SOLUTION: The image processor is provided with a labeling part 102 for extracting a character contained in the image data of a raster form and obtaining the size of the extracted character, and an approximation method determination part 104 for determining whether to use curve approximation for the conversion of the character, on the basis of the obtained size. When it is determined to use the curve approximation, the character is converted to a vector form, by respectively performing linear approximation or curve approximation of the respective parts of the contour of the character. When it is decided that curve approximation is not to be used, the character is converted to the vector form, by performing the linear approximation of the respective parts of the contour of the character, without performing curve approximation.

摘要： An information processing device enables shaggy to be inconspicuous in a short processing time without using data such as in a look-up table. The information processing device (1) includes a display control section (16) for determining the gray scale of the displaying pixels out of the pixels. The display control section (16) includes a distance calculating subsection (20), a gray-scale correcting subsection (21), and a display data generating subsection (22). A group of displaying pixels of one column arrayed in the direction of the line width, which are part of pixels constituting the displaying pixels of a symbol, is defined as an element pixel group. The distance calculating subsection (20) calculates the distance in the direction of the line width between an element line segment and the center point of each element pixel group including pixels overlapping with the element line segment. The gray-scale correcting subsection (21) corrects the gray scale of the pixel at one end included in the element pixel group containing the center point to a gray scale which is between a specified gray scale and the gray scale of the background of the displayed symbol and which corresponds to the calculated distance. The display data generating subsection (22) generates display data for displaying the symbol on a display screen according to the correction by the gray-scale correcting subsection (21).

摘要： Even when a jaggy occurs in an original image, the image is accurately enlarged and a good image cannot be obtained as a result. In the case of performing pixel interpolation on an image in a dot matrix state, image data is entered in step 100, the whole image is scanned while shifting a marked pixel, and whether or not an edge exists in the direction of 45 or 135 degrees by using the marked pixel as a reference is detected in step 115. When an edge at 45 or 135 degrees exists, the edge is smoothed in the direction of either 45 degrees in step 120 or 135 degrees in step 125. After that, pixel interpolation is carried out irrespective of the presence or absence of an edge. Consequently, when there are irregular edges, it can be prevented that an image is directly subjected to pixel interpolation and a jaggy occurs.
