Samsung patents method to fix colors in dark photos using adaptive math
Samsung describes a technique that analyzes a photo taken in low light to calculate specific color adjustments. It then applies these adjustments to improve the visual quality of the image before it is displayed on the screen.
In the filing’s own words
A method includes obtaining, using at least one processing device of an electronic device, an input image frame captured using an imaging sensor. The method also includes determining, using the at least one processing device, parameters of an adaptive affine color correction model based on the input image frame. The method further includes performing, using the at least one processing device, image visual quality enhancement using the adaptive affine color correction model to generate an enhanced image frame based on the input image frame. In addition, the method includes initiating, using the at least one processing device, display of a rendered image based on the enhanced image frame.
What exactly they claim (claim 1)
1. A method comprising: obtaining, using at least one processing device of an electronic device, an input image frame captured using an imaging sensor; determining, using the at least one processing device, parameters of an adaptive affine color correction model based on the input image frame; performing, using the at least one processing device, image visual quality enhancement using the adaptive affine color correction model to generate an enhanced image frame based on the input image frame; and initiating, using the at least one processing device, display of a rendered image based on the enhanced image frame.
