Why it mattersIt aims to keep screen colors consistent and accurate even when the main processor is in a low-power sleep mode.

In the filing’s own words

A method performed by an electronic device is provided. The method includes based on a sleep state of a first processor of the electronic device being released, setting a first region of interest set including a plurality of regions of interest, on a display of the electronic device during release of the sleep state, obtaining first color information about the set first region of interest set, compensating an image displayed on the display based on the obtained first color information during release of the sleep state, obtaining first color information for the first region-of-interest set, and compensating an image displayed on the display based on the obtained first color information, based on identifying that the image is stopped during release of the sleep state, setting a second region-of-interest set including a plurality of regions of interest on the display before entering the sleep state, and obtaining the first color information about the first region of interest set, based on entering the sleep state, obtaining second color information about the second region of interest set on the basis of entering the sleep state, and compensating the image on the basis of the first color information and the second color information.

What exactly they claim (claim 1)

1. An electronic device comprising: sensor circuitry including an illumination sensor; a display including display driving circuitry; memory, comprising one or more storage media, storing instructions; a first processor; and a second processor, wherein the instructions, when executed by at least one of the first processor or the second processor individually or collectively, cause the electronic device to: based on a sleep state of the first processor being released, set, on the display, a first region-of-interest set including a plurality of regions of interest, obtain first color information for the first region-of-interest set, and compensate an image displayed on the display based on the obtained first color information, based on identifying that the image is stopped during release of the sleep state, set, on the display, a second region-of-interest set including a plurality of regions of interest before entering the sleep state, and obtain the first color information for the first region-of-interest set, and based on entering the sleep state, obtain second color information for the second region-of-interest set, and compensate the image based on the first color information and the second color information.
