摘要： Methods, systems, and media to calibrate a reprographic system are disclosed. Embodiments of the invention may calibrate a component like scanner and/or printer in response to user input and/or coupling the component to the reprographic system. More specifically, embodiments may generate a curve that describes tone differences between an image scanned by a scanner or an image printed by the printer by comparing the outputs to acceptable tone descriptions for the image. Some embodiments comprise a graphical user interface (GUI) to communicate with the user, allowing the user to select user preference curves to change, for example, the brightness of an image being copied. Some embodiments incorporate network and phone system interfaces to communicate with remote components as well as to receive input from and/or output to other systems via email, facsimile, etc.

摘要： A method (and system) for changing spatial resolution of an image includes systematically creating an image scaling look-up table including at least one pixel replacement pattern and applying a scaling algorithm to modify the image using the image scaling look-up table, thereby allowing a user to scale binary images with easy control of dot gain, output bit depth and other printer parameters.

摘要： A method, computer program product and system for detecting and compensating for color misregistration. A black/white edge or a solid color edge on a target may be scanned. A black/white edge may refer to a black image, e.g., black text, on a white surrounding background having a rapid spatial transition from black to white. A solid color edge may refer to a solid color image, e.g., solid color text, on a white surrounding background having a rapid spatial transition from color to white. A curve of gray values versus spatial pixel positions for each color channel, e.g., red, green and blue color channels, may be generated. A misregistration error may then be calculated by calculating the offset between the color channel curves. The misregistration error may then be used to calibrate the scanner to compensate for the detected color misregistration.
摘要翻译：一种用于检测和补偿颜色错配的方法，计算机程序产品和系统。可以扫描目标上的黑色/白色边缘或纯色边缘。黑白边缘可以指白色周围背景上的黑色图像，例如黑色文本，其具有从黑色到白色的快速空间转变。纯色边缘可以指在白色周围背景上具有从颜色到白色的快速空间转变的纯色图像，例如纯色文本。可以生成灰度值与每个颜色通道（例如红色，绿色和蓝色通道）的空间像素位置的曲线。然后可以通过计算颜色通道曲线之间的偏移来计算重合失误。然后可能会使用重合失误来校准扫描仪以补偿检测到的颜色重合失调。
