Abstract
The present invention provides a method and system for processing an image. The method comprises: acquiring high-frame data and low-frame data of a target object, and acquiring initial exposure time to complete the high-frame data and the low-frame data; calculating a proportion of overexposed pixel points and a proportion of underexposed pixel points in the low-frame data; adjusting the initial exposure time according to a magnitude of the proportion of the overexposed pixel points and a magnitude of the proportion of the underexposed pixel points to obtain target exposure time; and acquiring target high-frame data and target low-frame data according to the target exposure time, and replacing overexposed pixel points in the target high-frame data with pixel points of the target low-frame data. The initial exposure time is adjusted according to the proportion of the overexposed pixel points to obtain the target exposure time, the target high-frame data and the target low-frame data are acquired according to the target exposure time, and the overexposed pixel points in the target high-frame data are replaced with the pixel points of the target low-frame data, thus the quality of a picture is improved.
