Abstract

The invention provides an image processing method, an image processing apparatus, and a terminal. The method comprises the following steps: obtaining image data of N images, wherein N is an integer greater than 1; respectively performing pixel merging processing based on a first scale on the image data of the N images to obtain image data of a first image obtained by merging the N images; and performing upsampling on the image data of the first image obtained by merging the N images based on a super-resolution reconstruction algorithm to obtain image data of a first super-resolution image, wherein the resolution of the first super-resolution image is greater than the resolution of the image obtained by merging the N images. By adoption of the scheme, a better dynamic range and more detailscan be obtained on the premise of ensuring the image resolution.

Description

technical field [0001] Embodiments of the present invention relate to the field of computers, and in particular, to an image processing method, an image processing device, and a terminal. Background technique [0002] The demand for mobile phone photography is increasing day by day, but in low-light shooting environment, such as the ambient brightness is lower than 30lux (lux), such as cinemas, bars, KTV, etc., if there is no other auxiliary equipment, the ambient light is too dark, the camera's If the incoming light is small, the captured image will be dark, and a clear and recognizable image cannot be captured. [0003] In order to solve this problem, some manufacturers add a flash to the rear camera of the mobile phone to improve the shooting effect in the dark environment. However, when shooting, the flash often makes people's eyes dazzled, and the user's eyes will appear to be temporarily unable to see things clearly. There are also some mobile phones that add a soft ...
