摘要： PROBLEM TO BE SOLVED: To provide a technique for counteracting an effect of density-dependent blurring to sharpen digital images to be printed. SOLUTION: A sharpening filter is disclosed for performing density-dependent sharpening on digital images. In one embodiment, a digital image to be sharpened is decomposed into a plurality of high-pass versions of the image at different resolutions. These high-pass images are gained at each resolution and recombined with the original image to produce a sharpened version of the image. The gains that are applied at each resolution are density-dependent. As a result, the effects of density-dependent blurring are counteracted, such that the sharpness of the final printed image is independent of the print density. Techniques are disclosed for performing such density-dependent sharpening with a high degree of computational efficiency. COPYRIGHT: (C)2011,JPO&INPIT
摘要翻译：要解决的问题：提供一种用于抵消密度依赖模糊的效果以锐化要打印的数字图像的技术。公开了一种用于在数字图像上进行与密度相关的锐化的锐化滤波器。在一个实施例中，要锐化的数字图像以不同的分辨率被分解成多个图像的高通版本。这些高通图像在每个分辨率下获得并与原始图像重新组合以产生图像的锐化版本。在每个分辨率下应用的收益与密度相关。结果，与密度相关的模糊的影响被抵消，使得最终打印图像的清晰度与打印密度无关。公开了以高计算效率执行这种密度依赖性锐化的技术。版权所有（C）2011，JPO＆INPIT

摘要： An electronic camera of the present invention includes an image pickup device, a positional data generating section, a memory, and an image processing section. The image pickup device includes a light-receiving plane photoelectrically converting a subject image. On the image pickup device any given partial image area is readable from a maximal image area. The positional data generating section generates positional data on the partial image area to the maximal image area. The memory holds a first edge enhancing filter used for data on the entire image and a second edge enhancing filter whose filter size is set smaller than that of the first edge enhancing filter. The image processing section performs, using the second edge enhancing filter, edge enhancement processing on data on a partial image extracted from the partial image area based on the positional data.

摘要： A method and apparatus for processing gray level image data. Gray level image data is subjected to plural separate halftone screen processing to form plural separate halftone processed screen gray level image data. The current pixel is also analyzed for contrast index. In response to analysis of the contrast index blending coefficients for processing of the halftone screen modified image data is made. The respective halftone outputs of the screen processings are multiplied by the respective blending coefficient. The resulting blended halftone gray value of the current pixel as well as neighboring pixels are then subjected to a threshold criterion test to determine if this represents a substantially binary image file such as might occur in a saturated text image file. The blended halftone gray value data for the current pixel is subjected to gray level edge enhancement processing to replace certain binary pixels adjacent an edge to reduce anti-aliasing effects. A signal resulting from the threshold criterion test is used to determine whether there is output to the printer or display of an edge enhanced version of the current blended halftone pixel or a pixel value representing the blended halftone pixel.

摘要： A method and system converts a binary image into an analog image by first tagging pixels that are part of edges in the digital image and using this tagging information to eliminate such tagged pixels from the digital filtering process. The elimination of such tagged pixels from the digital filtering process substantially eliminates artifacts near the edges, thereby reducing any distraction from the perceived quality of the output image.

SOLUTION: The image processing apparatus which generates output image data based on multi-level image data is provided with: a calculation part 300 which calculates maximum density and minimum density in a pixel block 301 comprising the predetermined number of pixels including attentional pixel data out of the multi-level image data; an error diffusion processing part which generates gray-scale pixel data from the attentional pixel data according to an error diffusion method; a dither processing part which generates gray-scale pixel data according to a dither processing method; a distribution ratio determination part which determines a distribution ratio of the error diffusion method and the dither processing method on the basis of the calculated maximum density and the minimum density; a composition part which combines gray-scale pixel data for an attentional pixel which has been generated by the error diffusion processing part and the dither processing unit according to the determined distribution ratio and outputs the result. The distribution ratio determination part increases the distribution ratio of the error diffusion method to the dither processing method as a difference between the maximum density and the minimum density becomes larger.
