Abstract
An illumination processing method and apparatus relate to the field of video recording technologies, where a liquid crystal panel is disposed between a photosensitive sensor and a lens assembly, and an incident light from the lens assembly reaches the photosensitive sensor after passing through the liquid crystal panel. The method includes determining a highlight region on a first image captured from the photosensitive sensor, and turning down light transmittance of each pixel in an adjustment region on the liquid crystal panel, where the adjustment region corresponds to the highlight region. According to the illumination processing method and apparatus, occurrence of a highlight blooming phenomenon can be avoided as much as possible, thereby avoiding loss of valid image information.
