Image processing method for brightness correction in images
The patent US12075199B2 outlines an innovative image processing method that enhances the display of images by allowing users to manipulate brightness levels through correction points. The method involves displaying a first image alongside a first correction point associated with a specific brightness. Users can move this correction point along a designated axis, resulting in the generation of a second image that maintains the original brightness within a defined range. Additionally, a second correction point can be displayed and similarly adjusted, enabling the generation of a second image that reflects a different brightness level within another specified range. This dual correction mechanism allows for nuanced control over image brightness.
Further details of the patent include the option to visually represent the brightness ranges with lines or curves, enhancing user interaction. The method also allows for the adjustment of brightness levels, including the possibility of transitioning between different brightness values linearly across the image. The technology is applicable to portable terminal devices and projectors, where it can be integrated into image display systems. The patent emphasizes the use of a non-transitory computer-readable medium to store the program that executes these image processing functions, ensuring that the method can be effectively implemented in various electronic devices.
