Image fusion method and system

The invention discloses an image fusion method and system. The method comprises the steps of starting a shooting function, and starting a long-focus camera and a wide-angle camera at the same time; obtaining and storing a first image shot by the long-focus camera and a second image shot by the wide-angle camera; based on different focal length requirements in different camera shooting modes, enhancing the image quality of the camera in the corresponding focal length by fusing the first image and the second image, and obtaining a shot image. According to the invention, image output quality and effect requirements in different camera shooting modes are met, pixel advantages and focal length advantages of the long-focus camera and the wide-angle camera are integrated, and the utilization rate of existing hardware resources is increased to the maximum. 本发明公开了一种图像融合方法及系统，该方法包括：启动拍摄功能，长焦摄像头和广角摄像头同时启动；获取并存储长焦摄像头拍摄的第一图像和广角摄像头拍摄的第二图像；基于不同摄像模式下的不同焦段需求，通过融合第一图像和第二图像来强化对应焦段摄像头的画质，得到拍摄图像；本发明满足了不同摄像模式下的图像输出质量和效果需求，并综合长焦摄像头
