Abstract: In an example, a method of gamut mapping may include generating a plurality of color values in a first color space based on a plurality of measured color values in a second color space using a color specification that maps color values corresponding to the second color space to color values corresponding to the first color space. The method may include generating a second-order or higher response-surface regression model that maps color values corresponding to the first color space to color values corresponding to the first color space.

Abstract: In an example, a method of gamut mapping may include generating a first second-order or higher response-surface regression model that maps color values corresponding to the second color space to color values corresponding to the first color space. The method may include generating predicted color values for measured color values by inputting measured color values into the first second-order or higher response-surface regression model. The method may include generating, based on predicted color values and a plurality of color values, a second second-order or higher response-surface regression model that maps predicted color values output by the first second-order or higher response-surface regression model corresponding to the first color space to color values corresponding to the first color space.

Abstract: Systems and methods for using a mobile device to manage the color of a digital display on the mobile device are disclosed. The mobile device has a display architecture which it can self-manage. The mobile device can display test patterns that are then sensed by a color sensor, which may be with the mobile device or separate from the mobile device. The mobile device then analyzes the color attributes of the test patterns and generates color management data that includes adjustments to be made to the display architecture. The mobile device may then receive the color management data and adjust its display architecture accordingly.

Abstract: This disclosure describes techniques for calibrating and adjusting the white point of a display. The techniques for calibrating and adjusting the white point of a display may receive data indicative of a target color temperature for a white point of a display, and provide one or more user interface components that allow a user to select between multiple different candidate white points where each of the of the candidate white points has a correlated color temperature that corresponds to the target color temperature Different target white points for a display may exhibit different levels of luminance loss and/or tint. The techniques for calibrating and adjusting the white point of a display may allow a user to evaluate the trade-off between the luminance loss characteristics and/or tint characteristics of different white points.
Abstract translation: 本公开描述了用于校准和调整显示器的白点的技术。 用于校准和调整显示器的白点的技术可以接收指示显示器的白点的目标色温的数据，并提供允许用户在多个不同候选白点之间进行选择的一个或多个用户界面组件， 候选白点中的每一个具有对应于目标色温的相关色温。显示器的不同目标白点可以呈现不同程度的亮度损失和/或色调。 用于校准和调整显示器的白点的技术可以允许用户评估不同白点的亮度损失特性和/或色调特性之间的权衡。

Abstract: Techniques are described generally related to perceptual attribute adjustment. In some examples, the perceptual attribute adjustment may be performed by a color correction unit as part of the functionality of the color correction unit to correct deficiencies in the ability of a display to display particular colors. In this manner, the techniques may allow for current display processors to implement the described techniques without needing hardware modification.

Abstract: In an example, a method of calibrating a white point of a display may include receiving a plurality of color values, and one or more measured color values corresponding to one or more colors displayed by a first target display. The method may include generating, based on the plurality of color values and the one or more measured color values, a second-order or higher response-surface regression model that maps color values corresponding to a second color space to color values corresponding to a first color space. The method may include generating predicted color values for a specified white point by inputting a plurality of specified color values corresponding to the specified white point into the second-order or higher response-surface regression model, where each predicted color value may correspond to the first color space and each of the specified color values may correspond to the second color space.
