Abstract: This specification describes various embodiments that relate to methods for providing a wideband colorimeter that can include more accurate outputs. In one embodiment, a narrowband instrument, such as a spectrometer or spectrograph, can be used for calibration of a wideband colorimeter, so that more accurate outputs can be provided. In one embodiment, an optical test equipment, which consists of both a wideband colorimeter and a narrowband spectrograph, can be used for providing a more accurately calibrated wideband colorimeter. As an example, a spectra-camera, which is a hybrid system consisting of both a wideband colorimeter and a narrowband spectrograph, can be used for simultaneous testing by both the wideband colorimeter and the narrowband spectrograph. By doing simultaneous testing, accurate calibration of the wideband colorimeter can be achieved. This specification further describes a mathematical model to characterize a wideband three channel colorimeter with a narrowband multiple channel spectrometer.

Abstract: The described embodiments provide a system that facilitates a switch from using a first graphics-processing unit (GPU) to using a second GPU to drive a display. During operation, upon generation of a request to switch from using the first GPU to using the second GPU as a signal source for driving the display, the system obtains a transform (such as a lookup table) that enables the displayed color output from the second GPU to substantially match the displayed color output from the first GPU. The system then makes the transform available for use by the second GPU in driving the display.

Abstract: Systems, methods, and devices for white point calibration using subtractive color measurements are provided. Specifically, a white point of a display may be calibrated using subtractive color measurements rather than merely additive color measurements. In one example, a display having red, green, and blue pixels may measure the responses in a subtractive color space (e.g., CMY) rather than additive color space (e.g., RGB). Measurements of the display response using subtractive color space may involve providing image data to two or more color channels at once. Thus, any crosstalk effect between channels may be accounted for, even though the same crosstalk effect might not be apparent using additive color measurements in which only a single channel color channel were measured.
