[0031] see figure 1 , is a flowchart of the first embodiment of the image processing method of the present invention, the image processing method is applied to a mobile terminal with a color camera and a black and white camera, and the image processing method includes:

[0032] Step 101, acquire the first auto-focus position of the color camera.

[0033] In the embodiment of the present invention, before the target is automatically focused by the color camera, the shooting mode can be set to a dual-camera mode in which a color camera and a black and white camera are used for shooting. In addition, the autofocus can be contrast detection autofocus or phase detection autofocus, or a combination thereof, but the present invention is not limited thereto, and any applicable autofocus technology can be applied to the present invention. Here, contrast detection autofocus calculates the sharpness weighted value of each frame of image to obtain the image sharpness measurement value of...

Abstract

An embodiment of the present invention provides an image processing method and a mobile terminal. The image processing method includes: acquiring the first auto-focus position of the color camera; setting the focus position of the black-and-white camera as the first auto-focus position; acquiring the first auto-focus position of the color camera The first color image and the first black-and-white image captured synchronously with the black-and-white camera at the first auto-focus position at the first moment; obtaining the second auto-focus position after the black-and-white camera performs auto-focus according to the first auto-focus position ; Obtain the second black-and-white image captured by the black-and-white camera at the second moment with the second auto-focus position; according to the first color image, the first black-and-white image and the second black-and-white image, perform synthesis through a preset synthesis algorithm to obtain a color result image. The image processing method of the embodiment of the present invention can avoid ghosting of the result image due to time asynchronous and unclear result image due to unclear input source image.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image processing method and a mobile terminal. Background technique [0002] At present, color and black and white dual cameras have been used more and more on portable terminals (such as laptop computers, tablets, mobile phones, personal digital assistants (PDAs), etc.), and more and more portable terminal manufacturers, Algorithm manufacturers have invested huge R&D costs, trying to improve the shooting effect of portable terminals through color and black and white dual cameras, especially in low-light conditions. [0003] On a portable terminal that uses color and black and white dual cameras, the current technical solution is that both the color camera and the black and white camera use an autofocus module, but the color camera module is mainly used for autofocus during autofocus, and the black and white camera is automatically focused on the basis of the color came...
