Engineering Contradiction Analysis
1Manufacturing precision
If a single-lens camera collects multiple frames of images at different times, then photographing quality can be improved through synthesis algorithms, but camera jitter or target object motion causes ghosting that requires complex ghost detection and compensation algorithms
Solution Approach 1:
The patent divides the imaging system into two separate lenses (first lens and second lens) positioned at different locations. Each lens captures images independently, allowing the system to segment the imaging task and use the spatial separation to eliminate ghosting effects through synthesis algorithms without requiring complex ghost detection and compensation.
2Manufacturing precision
If ghost detection and compensation algorithms are used to eliminate impact from camera jitter or target motion, then image quality is maintained, but photographing efficiency is reduced due to additional processing steps
Solution Approach 1:
By using two lenses positioned at different locations to capture images simultaneously, the patent eliminates the need for ghost detection and compensation processing. The spatial segmentation of the imaging system allows direct synthesis of images from different viewpoints, significantly improving photographing efficiency while maintaining image quality.
3Manufacturing precision
If multiple frames of images are collected at different times by a single-lens camera, then synthesis algorithms can improve photographing quality, but the time required for collecting multiple frames increases due to sequential capture
Solution Approach 1:
The patent uses two lenses to capture images simultaneously at the same moment, dividing the imaging task into parallel operations. This eliminates the sequential time delay inherent in single-lens multi-frame capture, reducing the time loss while maintaining the ability to perform synthesis algorithms for improved photographing quality.
Solution Approach 2:
By enabling simultaneous image capture with two lenses, the patent ensures continuous useful action without interruption or time delay. Both lenses capture images at the same moment, eliminating the sequential waiting time required for multiple frames in single-lens cameras, thus improving photographing efficiency.

AI summary
Embodiments of the present invention provide a photographing method for a dual-lens device, where the dual-lens device includes a first lens and a second lens that are disposed on a same plane, and the photographing method includes: acquiring a first image collected at a first moment by a first image sensor corresponding to the first lens and a second image collected at the first moment by a second image sensor corresponding to the second lens; 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; determining a multi-frame algorithm according to the photographing environment; and when an instruction for a photographing operation is received, generating a picture by using the multi-frame algorithm. According to the embodiments of the present invention, when photographing is performed by using a multi-frame algorithm, two frames of images can be collected at the same time by 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.
