Abstract

The invention provides an image processing method and device, and the method comprises the steps: shooting multiple frames of original images of a target object; detecting a target area corresponding to a target object in each frame of original image in the plurality of frames of original images; performing noise reduction based on artificial intelligence on the target area of each frame of original image to generate a noise reduction image; and carrying out high-dynamic synthesis on all the noise reduction images to generate a target image. Therefore, on one hand, an artificial intelligence-based noise reduction mode is adopted to reduce the noise of the image, more image details are reserved while the image purity is ensured, and on the other hand, noise reduction processing is only carried out on the target area, so that the noise reduction efficiency is greatly improved.

Description

technical field [0001] The present application relates to the field of imaging technology, and in particular to an image processing method and device. Background technique [0002] With the development of science and technology, camera technology based on technology has become more and more mature. In daily production and life, it has become a norm to use the built-in camera of a smart mobile terminal (such as a smart phone, a tablet computer, etc.) to take pictures. Therefore, with the normalization of the demand for taking pictures, how to improve the quality of images has become a major demand. [0003] In related technologies, the image quality is improved based on the noise reduction algorithm for the entire image. For example, the noise reduction processing based on the entire image requires a large amount of calculation, especially when multiple frames of images are used for high dynamic synthesis. The amount of data processing for denoising the whole frame image is ...
