摘要： A method, system and software are disclosed for applying an image mask for improving image detail in a digital image. An electronic representation of an image is scanned or captured using an image capture device. A dynamic image mask is generated from the electronic representation of the image. The dynamic image mask has sharp edges which are representative of rapidly changing boundaries in the original image and blurred regions in less rapidly changing areas. The dynamic image mask is applied to the electronic representation of the original image to produce an enhanced image. The enhanced image may have certain advantages. For example, in some embodiments, the enhanced image can be view on a display with much more viewing detail that conventional systems.

摘要： A method and apparatus for processing image data is described, comprising acquiring a frame of image data and compressing the dynamic range of the frame of image data using a dynamic range compression (DRC) algorithm that utilizes down-sampling, median filtering, and up-sampling. The DRC algorithm comprises down-sampling a frame of image data comprising a first array of pixels to generate a second array of pixels, applying a first median filter to the second array of pixels to generate a blurred array of pixels, up-sampling the blurred array of pixels, and removing at least a portion of low-frequency gradient data generated by previous steps from the frame of image data.

摘要： Binary screen image data redigitized in pixels are retouched, specifically to eliminate local screen defects such as dust artifacts and scratch artifacts. Defective screen dots are selected and recorded for the purpose of detecting screen defects. Then, dust artifacts and scratch artifacts or the like are removed from contaminated image data. Furthermore, missing points in the screen are also filled up, and inhomogeneous image regions are corrected in part. The production of visible moire effects in the retouched image data is avoided by the replacement of only small areas.

摘要： In embedding a dot pattern in an image, use of a dot pattern component that mainly aims at suppressing any degradation in image quality sacrifices accurate information detection. Conversely, use of a component that aims at improving the detection accuracy largely degrades the image quality. Error diffusion is executed for an image, a component of a dot pattern to be embedded is determined on the basis of the image that has undergone error diffusion, and the dot pattern is embedded in the image that has undergone error diffusion using the determined component.

摘要： Upon processing a visible light image signal and infrared image signal respectively obtained by illuminating a transparent document with light beams coming from a visible light lamp for mainly emitting visible light and an infrared lamp for mainly emitting infrared light, and photoelectrically converting optical images of the transparent document, a histogram is generated on the basis of the infrared image signal, a threshold value is calculated based on the histogram, and infrared image signal components equal to or smaller than the threshold value are extracted by comparing the calculated threshold value and infrared image signal components. Visible light image signal components corresponding to the extracted infrared image signal components are interpolated using surrounding visible light image signal components.

摘要： In image processing according to the prior art, the important part of photographic image data (referred to herein as the object) could not be determined and therefore required human participation. A computer 21 which is the core of image processing calculates an edginess which is an image variation from a differential value of data for adjacent picture elements in a step SA110, and determines object picture elements by selecting only images with a large variation in steps SA120, SA130. As optimum parameters for contrast correction and lightness compensation are calculated from image data for object picture elements in steps SA310-SA330, image processing indicators based on object picture elements are determined, and optimum image processing can be performed automatically. After summing a luminance distribution for each area of the image, which is a feature amount, while uniformly selecting picture elements in a step SB110, a reevaluation is performed by a weighting determined for each area in a step SB120, and a luminance distribution strongly influenced by the luminance distribution of the photographed object is thus obtained with uniform sampling. After determining the intensity of this luminance distribution in steps SB130-SB150, the image data is converted in a step SB160, and image processing can therefore be performed with optimum intensity while reducing the processing amount.

摘要： A method for halftoning includes the steps of defining a first set of weight sets, and defining a second set of weight sets. A first error associated with a first pixel location of a plurality of pixel locations is diffused to a first neighboring at least one pixel location using a first weight set selected from the first set of weight sets, and a second error associated with a second pixel location of said plurality of pixel locations is diffused to a second neighboring at least one pixel location using a second weight set selected from the second set of weight sets. The first diffusing step and the second diffusing step are alternately performed along each scanline in the image to reduce visual artifacts.
