An image processing method and device

Abstract

An image processing method and device for reducing motion blur. The method is as follows: when the terminal is previewing the image frames collected by the camera, when there is relative motion between the captured target object and the terminal, the first adjustment is made to the initial exposure parameters of the camera in the preview state, and the first adjustment is made. The first adjustment includes reducing the initial exposure time and increasing the initial exposure gain; after receiving the shooting instruction, the terminal performs a second adjustment on the first adjusted exposure parameter, and according to the first adjusted exposure parameter generating a first exposure frame, and generating at least two second exposure frames according to the second adjusted exposure parameters, wherein the second adjustment includes reducing the first adjusted exposure time and increasing the first Adjusted exposure gain; the terminal fuses the first exposure frame and the at least two second exposure frames, and outputs a fused image.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an image processing method and device. Background technique [0002] Some terminals with the camera function will have varying degrees of motion blur when shooting moving objects. If the object being photographed moves at a high speed, there will be more serious smearing. However, moving scenes such as human body movement, object movement, and shaking of flowers and plants are important scenes that users pay attention to when taking photos. In order to improve the clarity of shooting moving objects, professional photographers are often equipped with expensive large apertures, and set appropriate aperture values ​​and shutter speeds to capture moving objects. But for mobile phone users who take pictures all the time, anytime, anywhere: firstly, the aperture of the mobile phone camera is fixed and cannot be expanded by itself, and cannot support adjusting the ap...

Problems solved by technology

[0005] The present application provides an image processing method and device, which are used to solve the problem that the ability of the terminal to reduce motion blur is insufficient due to the trade-off of the noise level, which limits the strength of reducing the exposure time when reducing motion blur by reducing the exposure time.
