PHOTOGRAPHING METHOD FOR DUAL-CAMERA DEVICE AND DUAL-CAMERA DEVICE

摘要

Embodiments of the present invention provide a photographing method of a dual-lens device, and a dual-lens device. The dual-lens device includes a first lens and a second lens that are arranged on a same plane of the dual-lens device. The photographing method includes: acquiring a first image collected by a first image sensor corresponding to the first lens; identifying a scenario of the first image to determine a photographing environment; determining, according to the photographing environment, a second ISP parameter corresponding to the second lens; acquiring a second image that is collected, by using the second ISP parameter, by a second image sensor corresponding to the second lens; and generating a preview image according to the second image. According to the embodiments of the present invention, a photographing environment is determined by using an image collected by one lens of the dual-lens device, an ISP parameter corresponding to the other lens is determined according to the determined photographing environment, and then a preview image is generated by using an image collected by the other lens. In such a manner of using two lenses to respectively determining a photographing environment and acquiring a preview image, picture flickering on the preview image can be avoided.
