Title:
ILLUMINATION PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/040483
Kind Code:
A1
Abstract:
The present invention relates to the technical field of camera shooting, and in particular to an illumination processing method and apparatus. A liquid crystal panel with adjustable light transmittance is arranged between a light sensing sensor and a lens; and incident rays from the lens pass through the liquid crystal panel and then reach the light sensing sensor. The method comprises: determining a highlight region of a first image acquired from the light sensing sensor; and turning down the light transmittance of each pixel point in an adjustment region corresponding to the highlight region on the liquid crystal panel. The illumination processing method and apparatus provided in the embodiments can prevent the occurrence of a strong light blooming phenomenon to the greatest extent, so that the loss of effective information about an image can be avoided.
