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： The present disclosure relates to a method and system for processing isolated dots of an image to be printed by a printer. The method includes detecting whether pixels corresponding to an isolated dot in the image are in an on state. A first sum of pixels that are in an on state in a first pixel ring surrounding the pixels corresponding to the isolated dot when the pixels in the isolated dot are detected to be in the on state is determined. The first sum of pixels in the first pixel ring that are in the on state is compared with a first threshold sum. A first number of pixels in at least a second pixel ring either comprising of or surrounding the pixels corresponding to the isolated dot are turned on when the first sum of pixels in the on state is less than the first threshold sum.
