Imaging method and device based on dual cameras

Abstract

This application proposes an imaging method and device based on dual cameras. After determining the ambient brightness, the main camera and the secondary camera are determined from the dual cameras according to the ambient brightness, and the primary camera is used to capture the first captured image, and the secondary camera is used to capture the first image. Take the second image. Generate an imaged image according to the first captured image, calculate depth information of the imaged image according to the first captured image and the second captured image, and then perform blurring processing on the imaged image according to the depth information of the imaged image to obtain a desired target image. Since the high-resolution camera is used as the first camera, and the high-sensitivity camera is used as the second camera, and the primary and secondary cameras are switched between the first camera and the second camera according to the ambient brightness, the performance of the primary and secondary cameras can be achieved. Matching the brightness of the current environment ensures the imaging effect, and solves the technical problem of the poor imaging effect of the dual cameras in the dark light environment in the prior art.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to an imaging method and device based on dual cameras. Background technique [0002] Dual cameras have been increasingly applied to mobile terminal devices. The dual cameras in the prior art often use a telephoto lens and a wide-angle lens. The telephoto lens is used to take photos, and the wide-angle lens is used to assist in calculating the depth information of the photos for subsequent image blurring. [0003] However, the dual camera in the related art has a better imaging effect in an environment with higher brightness and higher light, but in a dark environment, the imaging effect is relatively poor. Contents of the invention [0004] This application aims to solve one of the technical problems in the related art at least to a certain extent. [0005] For this reason, the present application proposes an imaging method based on dual cameras to improve...
