AI Technical Summary

Problems solved by technology

However, limited by the maximum frame rate of the terminal, the time interval for collecting multiple frames of images is usually longer
During this time interval, the hand-held terminal shakes when shooting, so the image after combining the collected multi-frame images may not be clear.

Abstract

An embodiment of the present invention provides a terminal, including: M cameras, for taking continuous K shots of the same scene, where M≥2, K≥2, and each of the M cameras is simultaneously A frame of image is collected; the processor is connected with the M cameras, and is used for registration according to the images obtained by the K times of shooting, and performing temporal domain and spatial domain filtering on the registered images. In the embodiment of the present invention, multiple cameras are installed on the terminal. Since multiple cameras collect images at the same time during each shooting, the time interval for the terminal to collect a certain number of images is shorter than that of a single camera. The possibility of hand shaking or object movement is also reduced accordingly, so that the image quality of the synthesized image is better than that of a multi-frame image synthesized by continuous shooting with a single camera.

Description

technical field [0001] Embodiments of the present invention relate to the field of image processing, and more specifically, to a method and terminal for multi-frame noise reduction. Background technique [0002] Limited by the size and cost of the terminal, the area of ​​the lens and sensor of the terminal camera is relatively small, and the quality of the captured image is poor. In night scenes or low-light environments, the quality of captured images will be worse due to weak light. [0003] In order to improve the shooting effect of the terminal, the multi-frame noise reduction technology is gradually applied to the image processing of the terminal. Specifically, the same scene is first shot multiple times to obtain multiple frames of images; then the multiple frames of images are combined into one frame of image by using the characteristics of different image noise generation parts, so as to achieve the purpose of noise reduction. [0004] Multi-frame noise reduction t...
