Method for image-processing and mobile terminal using dual cameras

A mobile terminal, comprising circuitry configured to:

• select n number of first images captured by a primary camera in response to a shooting operation and m number of second images captured by a secondary camera in response to the shooting operation;
• perform a synthesizing-denoising process on the n number of first images and the m number of second images respectively to obtain a primary image and a secondary image respectively;
• obtain depth information of the primary image based on the primary image and the secondary image;
• and
• perform a blurring process for the primary image based on the depth information of the primary image to obtain a target image;
• wherein the primary camera and the secondary camera each have a focusing motor, the secondary camera has a lower resolution than the primary camera, and the secondary camera is configured to be focused for the primary camera and the secondary camera;
• and
• wherein the primary camera is configured to be focused by reading a second drive current of the focusing motor of the secondary camera during focusing of the secondary camera, determining a first drive current of the focusing motor of the primary camera according to the second drive current such that a focusing requirement of the primary camera matches a focusing requirement of the secondary camera, and focusing the primary camera by the first drive current.

A non-transitory computer readable medium storing instructions which, when executed by a processor, cause the processor to perform a method for image processing, the method comprising:

• selecting n number of first images captured by a primary camera in response to a shooting operation and m number of second images captured by a secondary camera in response to the shooting operation;
• performing a synthesizing-denoising process on the n number of first images and the m number of second images respectively to obtain a primary image and a secondary image respectively;
• obtaining depth information of the primary image based on the primary image and the secondary image;
• and
• performing a blurring process for the primary image based on the depth information of the primary image to obtain a target image;
• wherein the primary camera and the secondary camera each have a focusing motor, the secondary camera has a lower resolution than the primary camera, and the secondary camera is configured to be focused for the primary camera and the secondary camera;
• and
• wherein the primary camera is configured to be focused by reading a second drive current of the focusing motor of the secondary camera during focusing of the secondary camera, determining a first drive current of the focusing motor of the primary camera according to the second drive current such that a focusing requirement of the primary camera matches a focusing requirement of the secondary camera, and focusing the primary camera by the first drive current.
