Problems solved by technology

[0004] At present, in the scene where multiple frames of original images are required to synthesize the target image, for example, in the special scene of night scene, multiple frames of original images are usually collected for high dynamic synthesis, but noise will be introduced during the process of collecting multiple frames of original images, resulting in The final composite image is not clear

Embodiment Construction

[0029] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

[0030] In the related art, in the scene where multiple frames of original images are required to synthesize the target image, since the number of frames taken is large and the frame acquisition time is long when the target image is obtained, there may be smearing in the captured image due to shaking, or Noise will be introduced during the shooting process, resulting in unclear target images for subsequent synthesis.

[0031] For this reason, the application proposes an image processing method based on multi-frame images, by ...

Abstract

The invention provides an image processing method and device based on multiple frames of images. The method comprises the steps that multiple frames of original images are acquired, a neural network model corresponding to each frame of original image is selected according to the exposure degree of each frame of original image for noise reduction processing, so that each frame of original image after noise reduction is obtained, and a target image is synthesized through each frame of original image after noise reduction. Therefore, by performing noise reduction processing on multiple frames oforiginal images, the effectiveness of noise reduction is improved, image details are reserved while image noise is reduced in the synthesized target image, an imaging effect with better definition isobtained, and the imaging effect of the target image is 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 based on multi-frame images. Background technique [0002] With the development of smart terminal technology, the use of mobile terminal devices (such as smart phones, tablet computers, etc.) is becoming more and more popular. Most mobile terminal devices have built-in cameras, and with the enhancement of mobile terminal processing capabilities and the development of camera technology, the performance of built-in cameras is becoming more and more powerful, and the quality of captured images is also getting higher and higher. Nowadays, mobile terminal devices are easy to operate and easy to carry, and more and more users use mobile terminal devices such as smart phones and tablet computers to take pictures in daily life. [0003] While smart mobile terminals bring convenience to people's daily photography, people's requirements...
