摘要： Embodiments relate to systems and methods for dynamic sharpness control in system using binary to continuous tone conversion. Image data can be processed in the image path of a copier, printer, or other device to enhance sharpness based on user settings. The image can originate in a high-resolution and/or high-color format. The user can select sharpness values to provide better rendered detail. A front-end high-pass 2D filter can be adjusted in response to the settings. A binarized version of the image data is produced in the downstream path. At the back of the image path, the image would conventionally be sent through a binary data to extended contone (BDEC) low-pass filter, set to a fixed level, to produce contone output, counteracting the user's sharpness settings. Instead of applying a fixed back-end filter, that stage can be dynamically adjusted to correspond to the user's sharpness settings, reducing the low-pass effect proportionately.

摘要： When generating output image data represented by a reduced number of gray levels from gray level image data, an image processing apparatus subtracts a pixel value of a selected pixel from a pixel value of adjacent pixel, amplifies the reduced value obtained by the subtraction, adds the amplified value to a numerical value in a numerical matrix, and finds a pixel value in the output image data represented by a reduced number of gray levels of pixel values, based on a value obtained by further adding a value obtained by adding the amplified value to the numerical value in the numerical matrix to a predetermined value.

摘要： As provided herein, there are supplied teachings to systems and methods for resizing a halftone image using halftone tile parameters. One approach entails receiving into a digital imaging system, a digital halftone image and a desired resizing factor for that digital halftone image. The system will then define cells within the digital halftone image and determine from those cells, a number of halftone tile seams to suitable for manipulation. The orientation of these halftone tile seams is dictated by the received desired resizing factor. The seam energy of these halftone tile seams is then determined according to an energy metric so as to provide indication of a number of low energy determined halftone tile seams. The number of low energy seams identified is sufficient to achieve the desired resizing factor. A resizing of the halftone image is then performing by iteratively deleting the low energy determined halftone tile seams within the halftone image. The resized halftone image may then be printed on a printer.
