Method and device for processing scene images

Abstract

The invention discloses a scene image processing method and device, which mainly includes: acquiring the gray value of each pixel in the pre-shot image of the scene to be photographed, and determining respectively according to the determined first combination area and the second combination area The first exposure amount and the second exposure amount respectively affect the gray value of each pixel point in the first image area corresponding to the first combination area in the first image obtained by shooting with the first exposure amount, and the gray value of each pixel point in the first image area corresponding to the first combination area when shooting with the second exposure amount In the obtained second image, the gray value of each pixel in the second image area corresponding to the second combination area is adjusted, and the adjusted two image areas are spliced ​​to obtain a scene image. Thus, the problem of overexposure or underexposure of the image due to the large difference between light and dark in the shot scene is avoided, the scene details of the shot scene are preserved to the greatest extent, and at the same time, the difference between the light and dark areas in the shot scene is restored to the greatest extent. Brightness relationship, so that the image quality of the scene is more high-quality.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a scene image processing method and device. Background technique [0002] With the advancement of technology and the development of the times, users have higher and higher requirements for image quality, especially for high-performance experience of devices with image capture functions. [0003] However, most of the devices with image capture function are designed and used according to the most common lighting environment. For example, the most common digital cameras can be By adjusting the aperture, shutter and other attribute settings for optimal shooting, high-quality image effects can be obtained. [0004] However, in a shooting scene with a large difference between light and dark, for example: a building covered with neon lights at night, because the neon lights of the building are brighter, the night is darker, so when the property settings of the digital ...
