    • User interfaces are provided that allow for the display of a target element that may be used to adjust a gamma value of a display device. The target element includes three layers. A bottom static layer is alternating light and dark lines, which in one instance may be black and white lines of equal height. A gray static layer is solid gray, and overlays some or all of the bottom static layer. A progressive layer gradually changes from a fully transparent are to an opaque area, and overlays some or all of the gray static layer. Additionally, a manipulation area is provided, which may be a sliding mechanism. The user may adjust the gamma to a higher value when the fully transparent area appears lighter than the opaque area, and may adjust the gamma to a lower value when the fully transparent area appears darker than the opaque area.
    • 提供了允许显示可用于调整显示设备的伽马值的目标元素的用户界面。 目标元素包括三层。 底部静态层是交替的浅色和暗色线,其在一种情况下可以是相同高度的黑色和白色线。 灰色静态层是实心灰色,并覆盖一些或全部底层静态层。 渐进层逐渐从完全透明的区域变为不透明区域,并覆盖部分或全部灰色静态层。 另外,设置有可以是滑动机构的操作区域。 当完全透明区域看起来比不透明区域更亮时,用户可以将伽马值调整到更高的值,并且当全透明区域比不透明区域更暗时,可以将伽马值调整到更低的值。

    • A method for determining (250) a change required in a selected base point in an input colorant space of a digital-image rendering system to obtain from the digital-image rendering system a desired reference output color to within a predetermined color tolerance comprises determining the required change based on a local approximation of the colorant/color relationship at the selected base point. Gradient points are automatically generated (210) that are proximate or coincident with the selected base point and that are different from any other base point than the selected base point. A linear approximation to the colorant/color relationship at the selected base point is computed (240) from the gradient points and the measured (230) output colors at the gradient points as rendered (220) by the digital-image rendering system and. The required change is determined from the local gradient of the colorant/color relationship at the selected base point.
    • 一种用于确定(250)在数字图像渲染系统的输入着色剂空间中选择的基点所需的改变以从数字图像呈现系统获得期望的参考输出颜色到预定颜色容差内的方法,包括: 基于在所选择的基点处的着色剂/颜色关系的局部近似所需的改变。 自动生成与所选择的基点接近或一致的并且与所选择的基点不同的任何其它基点的梯度点(210)。 从梯度点和由数字图像渲染系统渲染(220)的梯度点处的测量(230)输出颜色计算(240)所选基点处的着色剂/颜色关系的线性近似。 所需的变化由所选择的基点处的着色剂/颜色关系的局部梯度确定。

    • A printing system includes a printer arranged to render color images on print media and having a color gamut; a color measurement device embedded in the printer and arranged to measure colors, printed by the printer on a print medium, in a device-independent color space, and a color gamut constructor arranged to form, in an ad-hoc manner, a model representing the printer's color gamut with its boundary, based on a color measurement by the color measurement device of a set of color patches printed by the printer. The color gamut constructor is comprised in the printer or in a printer-driving program module arranged to run in a computer connected to the printer, or in both.
