Dual-Screen Photography Stimulating Vivid Expressions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminal devices face challenges in capturing vivid and excellent moments during photography due to low efficiency and poor user experience, as they struggle to stimulate a rich expression from subjects, often leading to missed opportunities.
Innovation Solution
The implementation of a photographing method and apparatus that utilizes a dual-screen system, where a viewfinder window is presented on one screen and preset playing content, such as text, images, or videos, is displayed on the second screen to attract and stimulate the subject's attention when specific feature parameters are matched, improving the likelihood of capturing a vivid expression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the photographer waits for the subject to naturally show a vivid expression, then the expression captured may be more natural, but the photographing time is significantly extended and excellent moments may be missed
Solution Approach 1:
The system performs preliminary action by displaying preset content (animations, images, or texts) on the second screen before the photographing moment occurs. This content is prepared in advance to stimulate the subject and induce vivid expressions, eliminating the need for prolonged waiting while ensuring high-quality captures when expressions naturally occur.
Solution Approach 2:
The second screen acts as an intermediary element between the photographer and the subject. It displays preset content that serves as a mediator to stimulate the subject's emotions and expressions, enabling the photographer to capture vivid moments without extended waiting periods.
2Loss of energy
If the device enters screen-off state during standby, then power is saved, but excellent photographing moments are missed
Solution Approach 1:
The system prepares photographing content and keeps the second screen active with preset content display before the actual photographing moment. This preliminary preparation ensures the device remains in a ready state without continuous high-power operation, enabling quick response when photographing opportunities arise while managing power consumption efficiently.
Solution Approach 2:
The system dynamically adjusts the screen states based on photographing needs. The first screen displays the viewfinder during active photographing, while the second screen dynamically displays preset content to stimulate the subject. This dynamic configuration allows the device to maintain photographing readiness without continuous full-power operation of both screens.
3Ease of operation
If the photographer manually operates the device to capture moments, then control over timing is maintained, but the likelihood of missing spontaneous expressions increases
Solution Approach 1:
The system implements feedback by continuously monitoring the subject's expressions through the camera and comparing them against predetermined expression criteria. When spontaneous vivid expressions are detected, the system provides feedback by triggering the photographing operation automatically, ensuring reliable capture of spontaneous moments while the photographer maintains overall control through the viewfinder interface.
Solution Approach 2:
The system performs self-service by automatically detecting spontaneous expressions and triggering photographing operations without requiring manual intervention for each capture. The photographer sets the parameters and presets, then the system autonomously monitors and captures moments, combining manual control with automated execution to improve reliability of capturing spontaneous expressions.

AI summary
A terminal device obtains a first instruction triggering a photographing function, presents a viewfinder window on a first screen, obtains a feature parameter of a target image, where the target image is an image presented in the viewfinder window, presents preset playing content on a second screen when the feature parameter of the target image matches a standard feature parameter, and performs a photographing operation. Therefore, after the photographing function is enabled, the viewfinder window is presented, and the preset playing content is played on the second screen, where the playing content may attract attention of a photographed target such that the photographed target is stimulated in a short time to show a vivid expression.
