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.

Abstract: A photographing method for a dual-lens device may include acquiring a first image collected at a first moment by a first image sensor and a second image collected at the first moment by a second image sensor; performing scene recognition on the first image and/or the second image, and performing depth estimation on the first image and the second image to determine a photographing environment; and when an instruction for a photographing operation is received, generating a picture using the multi-frame algorithm. When photographing is performed using a multi-frame algorithm, two frames of images can be collected at the same time using a dual-lens device, which can reduce impact caused by a jitter of the device or a motion of a target object, so that ghost detection and an elimination algorithm are not required, thereby reducing a photographing time.
