Problems solved by technology

[0006] To this end, this application proposes an image method and device based on multi-frame images, which solves the problem of image noise level when shooting night scenes by performing high-dynamic-range synthesis on multi-frame original images. High, the technical problem that affects the user experience, realizes the beneficial effect of noise reduction on both the bright light area and the dark light area in the high dynamic range image obtained by high dynamic synthesis, improves the effectiveness of noise reduction, and makes the noise reduction obtained The target noise reduction image can reduce the noise of the picture while retaining the image details, and obtain a clearer image, thereby improving the user experience

Embodiment Construction

[0035] 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.

[0036] For related technologies, when high dynamic and high dynamic range images are taken, the number of frames is more and the frame acquisition time is long, which may cause smears in the captured images due to shaking, or introduce noise during the shooting process, resulting in image blurring. For the problem of blurring, this application proposes an image processing method based on multi-frame images. By obtaining multi-frame original images, a high dynamic range image is synthesized based on the multi-frame original im...

Abstract

The invention provides an image processing method and device based on multiple frames of images, and the method comprises the steps: obtaining multiple frames of original images, carrying out the synthesis according to the multiple frames of original images, obtaining a high-dynamic-range image, and carrying out the artificial intelligence noise reduction of the high-dynamic-range image, so as toobtain a target noise reduction image. According to the method, noise reduction processing is carried out, the image noise and effective details of the high-dynamic-range image can be distinguished more accurately. Meanwhile, noise reduction processing is carried out after high-dynamic synthesis of a plurality of frames of original images. Therefore, both the bright light area and the dark light area in the high-dynamic-range image obtained through high-dynamic synthesis can be subjected to noise reduction, the noise reduction effectiveness is improved, image details are reserved while image noise is reduced through the target noise reduction image obtained through noise reduction, an imaging effect with better definition is obtained, and then the use experience of a user 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 also have high...
