[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

The embodiment of the invention provides an image processing method and a mobile terminal. The image processing method comprises: obtaining the first automatic focusing position of a color camera lens; arranging the focusing position of a black and white camera lens to be the first automatic focusing position; obtaining a first color image and a first black and white image synchronously captured by the color camera lens and the black and white camera lens at a first moment at the first automatic focusing position; obtaining a second black and white image captured by the black and white camera lens at a second moment at a second automatic focusing position; and obtaining a color result image through composition by means of a presetting composition algorithm according to the first color image, the first black and white image and the second black and white image. The image processing method provided by the embodiment of the invention is able to avoid the conditions that images generate ghosting caused by non-synchronous time and result images are intelligible caused by intelligible input source images.

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...
