Embodiment 1

[0066] An embodiment of the present invention provides an image processing method based on dual cameras.

[0067] In this embodiment, the execution subject is a mobile terminal with dual cameras.

[0068] The mobile terminal may be a terminal device such as a smart phone or a tablet computer. The dual cameras can be located on the front or back of the mobile terminal at the same time, or can be located on the front and back of the mobile terminal respectively.

[0069] When the dual cameras are respectively located on the front and back of the mobile terminal, at least one of the dual cameras can adjust the viewing angle by rotating, stretching, folding, etc., so that the viewing ranges of the dual cameras are the same or basically consistent, so that the dual cameras can shoot same picture.

[0070] The image processing method based on dual cameras of the present invention is described below in conjunction with the accompanying drawings, as image 3 Shown is a flow chart o...

Embodiment 2

[0088] In order to make the present invention more clear, this embodiment will further describe the dual camera-based image processing method of the present invention. The execution subject of this embodiment is a mobile terminal with dual cameras.

[0089] like Figure 4 Shown is a specific flow chart of the image processing method based on dual cameras according to the second embodiment of the present invention.

[0090] Step S410, in the captured image, determine the main object captured by the dual cameras.

[0091] The main subject refers to the subject of this shooting, which is the main prominent object in the image.

[0092] The main object photographed by the dual cameras is determined according to the depth information of the photographed object or according to the object selected from the photographed objects. Further, when the picture is taken, the depth information of each object in the picture is obtained, and the object whose depth value is within a preset ra...

Embodiment 3

[0113] This embodiment provides an image processing device based on dual cameras. The dual-camera-based image processing apparatus of this embodiment may be set in a mobile terminal with dual cameras.

[0114] like Figure 8 Shown is a structural diagram of an image processing device based on dual cameras according to a third embodiment of the present invention.

[0115] The calling module 810 is configured to call the first camera of the dual cameras to shoot black-and-white images, and call the second camera of the dual cameras to shoot color images.

[0116] The extraction module 820 is configured to extract the color parameter information of the black and white image and the color parameter information of the color image.

[0117] The adjustment module 830 is configured to adjust the color parameter information of the color image according to the color parameter information of the black and white image.

[0118] In one embodiment, the calling module 830 is configured to...

Abstract

The invention discloses an image processing method and device based on double cameras. The method comprises steps of calling a first camera in the double cameras to shoot black and white images, and calling a second camera in the double cameras to shoot color images; extracting color parameter information of the black and white images and color parameter information of the color images; and according to the color parameter information of the black and white images, adjusting the color parameter information of the color images. According to the invention, in order to overcome a problem of excessive exposure of the images, the first camera and the second camera in the double cameras are called to shoot the black and white images and color images separately; and according to the color parameter information of the black and white images with quite precise exposure degrees, the possibly excessively exposed color images are adjusted, and color images with the adjusted color parameter information are improved, thereby preventing the excessively exposed color images being displayed to users.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to an image processing method and device based on dual cameras. Background technique [0002] With the continuous development of mobile terminal technology, mobile terminals can take pictures, shoot videos, record data, query information and control other terminal devices. Therefore, mobile terminals rely on powerful functions and have become an indispensable part of people's daily life. [0003] At present, the camera pixel configuration of the existing mobile terminal is relatively high, so that the definition of the picture taken by the mobile terminal is high, and the picture taken by the mobile terminal can be restored to a high degree, and the life of the user can be recorded. However, in daily use, when using an existing mobile terminal to take a photo, the image is easily overexposed, causing problems such as image abnormality and low image quality, and the ...
