  • Patent number: 10825146
    Abstract: A method for image processing includes the following actions. After n frames of first images shot by a main camera are acquired and an auxiliary image shot by an auxiliary camera is acquired, synthetic noise reduction is performed on the n frames of first images to obtain a frame of main image. Depth information of the main image is further calculated according to the main image and the auxiliary image. Therefore, blurring processing is performed on the main image according to the depth information of the main image to obtain a required second image.

  • Patent number: 10757312
    Abstract: A method for image processing and a mobile terminal, and a computer readable medium are disclosed. In one method, n number of first images and m number of second images are acquired. The first images and the second images are captured by a primary camera and a secondary camera respectively, and both the n and the m are integers greater than 2. A synthesizing-denoising process is performed 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. Depth information of the primary image is obtained based on the primary image and the secondary image. A blurring process for the primary image is then performed based on the depth information of the primary image to obtain a target image.

  • Patent number: 10742860
    Abstract: A method and device for double-camera-based imaging are provided. The method includes the following actions. A first image is acquired by a main camera and a second image is acquired by an auxiliary camera. A main image resolution and an auxiliary image resolution are determined according to a determined shooting mode and resolutions of the main camera and the auxiliary camera respectively. The first image is converted into a main image with the main image resolution. The second image is converted into an auxiliary image with the auxiliary image resolution according to the second image. A required target image is obtained according to the main image and the auxiliary image.
