Problems solved by technology

[0004] However, when this kind of dual camera is used to shoot, the RGB image is much worse than the Mono image in terms of noise, details and dynamic range, which has become a major factor affecting the image quality of the fusion result
[0005] It can be seen that the image generated by the dual-camera fusion of the color camera + black and white camera in the prior art is limited by the RGB image, and there is a problem of poor image quality

Embodiment 1

[0044] This embodiment provides an image fusion method, please refer to figure 1 , figure 1 It is a flow chart of the image fusion method in the embodiment of the present invention, including:

[0045] Step S101, acquiring a color image taken with the flash turned on and a black-and-white image taken with the flash turned off, where the color image and the black-and-white image have the same subject;

[0046] Step S102, registering the black and white image and the color image;

[0047] Step S103, fusing the color information of the color image into the black and white image to generate a resultant image.

[0048] It should be noted that the method provided in this embodiment can be applied to the fusion of images captured by the two cameras separately, or can be applied to the fusion of images captured by the same camera in different shooting modes, which is not limited here.

[0049]It should also be noted that the cameras for acquiring the black-and-white image and the c...

Embodiment 2

[0106] Such as image 3 As shown, an image fusion device is provided, comprising:

[0107] An acquisition module 301, configured to acquire a color image taken when the flash is turned on and a black-and-white image taken when the flash is turned off, and the color image and the black-and-white image have the same shooting object;

[0108] Registration module 302, configured to register the black-and-white image and the color image;

[0109] The fusion module 303 is configured to fuse the color information of the color image to the black and white image to generate a resultant image.

[0110] In the embodiment of the present application, the device further includes:

[0111] A detection module, configured to detect and determine a clear region in the color image whose resolution is higher than a preset resolution value;

[0112] A superposition module, configured to superimpose the detail information of the clear region to a corresponding region on the black-and-white image...

Embodiment 3

[0116] Such as Figure 4 As shown, this embodiment provides an electronic device, including a memory 410, a processor 420, and a computer program 411 stored in the memory 410 and operable on the processor 420. When the processor 420 executes the computer program 411 Implement the following steps:

[0117] Obtaining a color image taken when the flash is turned on and a black-and-white image taken when the flash is turned off, the color image and the black-and-white image have the same subject;

[0118] registering said black and white image and said color image;

[0119] fusing the color information of the color image to the black and white image to generate a resultant image.

[0120] In this embodiment of the present invention, when the processor 420 executes the computer program 411, any implementation manner in Embodiment 1 of the present invention may be implemented.

[0121] Since the electronic device introduced in Embodiment 3 of the present invention is the device u...

Abstract

The invention discloses an image fusion method and device, electronic equipment and a medium. The method comprises the steps of obtaining a color image photographed in a flash lamp turn-on state and ablack and white image photographed in a flash lamp turn-off state, wherein a photographing object of the color image is the same as the photographing object of the black and white image; carrying outregistration on the black and white image and the color image; and fusing color information of the color image to the black and white image, and generating a result image. According to the method, the device, the electronic equipment and the medium provided by the invention, the problem that in the prior art, the image quality is low due to the fact that an image generated through fusion of double cameras: a color camera and a black and white camera is limited by the color image is solved, and the technical effect of improving the image quality is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image fusion method, device, electronic equipment and medium. Background technique [0002] With the increasingly fierce competition in the smart phone market, the focus of competition among major mobile phone manufacturers has gradually extended from the previous hardware arms race to the field of audio-visual entertainment, especially the camera performance of mobile phones. With the rapid iteration of mobile phones, the camera performance of single-camera mobile phones has reached the limit to a certain extent. If you want to make a breakthrough in the field of photography, you must rely on dual cameras. Therefore, in the past two years, many mobile phone manufacturers have launched dual-camera phones. . [0003] One of the more important dual cameras is a color (RGB) camera + black and white (Mono) camera. This type of dual camera is mainly used to improv...
