Abstract: The techniques of this disclosure are applicable to backlight display devices. For such devices, the backlight may have different backlight intensity settings in order to promote power conservation. The techniques of this disclosure may apply different adjustments to the display, depending on the backlight intensity setting. In one example, different color correction matrices may be applied for different backlight settings in order to achieve desirable adjustments in the device at the different backlight settings. The adjustments described herein may address chrominance shifts due to different backlight settings as well as cross-talk between color channels. The techniques may also be applicable to organic light emitting diode (OLED) displays that have different luminance settings, and some described techniques may be applicable to displays that have static or fixed luminance output.

Abstract translation: 本公开的技术可应用于背光显示装置。 对于这样的设备，为了促进功率节省，背光源可以具有不同的背光强度设置。 根据背光强度设置，本公开的技术可以对显示器应用不同的调整。 在一个示例中，可以针对不同的背光设置应用不同的颜色校正矩阵，以便在不同的背光设置下在设备中实现期望的调整。 本文描述的调整可以解决由于不同的背光设置以及颜色通道之间的串扰造成的色度偏移。 这些技术也可以应用于具有不同亮度设置的有机发光二极管（OLED）显示器，并且一些所描述的技术可以适用于具有静态或固定亮度输出的显示器。

Abstract: Described are a system and method to calibrate displays using a spectral-based colorimetrically calibrated multicolor camera. Particularly, discussed are systems and methods for displaying a multicolor calibration pattern image on a display unit, capturing the multicolor calibration pattern image with a multicolor camera having a plurality of image sensors, with each image sensor configured to capture a predetermined color of light, comparing a set of reference absolute XYZ coordinates of a set of colors from the multicolor calibration pattern with a set of measured XYZ color coordinates captured using the colorimetrically calibrated camera, and calibrating the display unit based on the comparison between the reference coordinates and the measured coordinates.
