Samsung patents image tweaks that make screens look brighter without using more power
The patent describes a method that adjusts the color intensity and contrast of an image to make it appear brighter to the human eye. It achieves this by tweaking specific colors rather than increasing the actual light output of the screen, which helps save battery life.
In the filing’s own words
One embodiment provides a computer-implemented method that includes increasing a chroma of one or more particular hues of an image for display on a display device. The one or more particular hues having at least a threshold magnitude of a visual perception effect based on a contrast between one or more colors and a background color. Perceptual brightness of the image is increased without changing actual brightness of the image. A lightness of at least one of two particular hues is reduced, by a specified amount, to increase global contrast between various hues.
What exactly they claim (claim 1)
1. A computer-implemented method comprising: increasing a chroma of one or more particular hues of an image for display on a display device, the one or more particular hues having at least a threshold magnitude of a visual perception effect based on a contrast between one or more colors and a background color; increasing perceptual brightness of the image without changing actual brightness of the image; and reducing, by a specified amount, a lightness of at least one of two particular hues to increase global contrast between various hues; wherein one or more radial weighting functions are used to adjust saturation and lightness of the image.
