Abstract
This disclosure generally relates to digital image and video signal processing, and more particularly to methods and systems for dynamic brightness correction. In one embodiment, an electronic circuit configured to perform an image correction method is disclosed, the method comprising: obtaining a pixel value of a color space component from an image; determining whether to perform mid-tone correction for the pixel value of the color space component; calculating, via the electronic circuit, a corrected pixel value based on the determination of whether to perform the mid-tone correction for the pixel value of the color space component; and outputting the corrected pixel value. The color space component may be one of: an Intensity component from a Hue-Saturation-Intensity color space; a Value component from a Hue-Saturation-Value color space; a Lightness component from a Hue-Saturation-Lightness color space; and a Brightness component from a Hue-Saturation-Brightness color space.
