Color correction to facilitate switching between graphics-processing units

摘要

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.

主权项

1. A method for providing consistently displayed color across a plurality of graphics-processing units (GPUs), comprising:
producing a transform based upon a measured color output of a first GPU from a plurality of GPUs; providing color output using the first GPU from the plurality of GPUs to a display; receiving a request to switch to a second GPU of the plurality of GPUs; and performing a switch to the second GPU, at least in part, by utilizing the transform to enable a displayed color output on the display from the second GPU to match the measured color output of the first GPU on the display prior to the switch.
