US 9,736,391 B2 · Photographing method of dual-lens device, and dual-lens device

Abstract

The present invention provides a photographing method for a dual-lens device. The dual-lens device includes a first lens and a second lens that are arranged on a same plane. The photographing method includes acquiring a first image collected by a first image sensor; identifying a scenario of the first image to determine a photographing environment, determining a second image signal processor (ISP) parameter corresponding to the second lens; acquiring a second image that is collected, according to the second ISP parameter, and generating a preview image. According to the present invention, a photographing environment is determined by using an image collected by one lens of the dual-lens device, and then a preview image is generated by using an image collected by the other lens.
