Rotating Mobile Terminal Camera Module for Accurate Selfie Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals with fixed camera modules positioned at the edge make it inconvenient to take selfies as the camera captures the upper part of the user's face instead of the front, due to the height difference between the user's eyes and the camera lens, making it difficult to adjust the direction accurately.
Innovation Solution
A mobile terminal design where a second body unit connected to a rotating shaft allows the camera module to automatically capture images within a prescribed angle range, enabling the user to take selfies at an appropriate angle without manual adjustment by controlling the camera module's activation and deactivation based on the angle between the first and second body units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the camera module is fixed to an edge region of the mobile terminal, then the terminal structure is simple, but the selfie capture accuracy deteriorates due to height difference between user's eyes and camera lens
Solution Approach 1:
The patent applies the dynamics principle by making the second body unit rotatable relative to the first body unit through a rotating shaft. The camera module is disposed on the rotatable second body unit, allowing it to dynamically adjust its orientation angle. This enables the camera to transition from a fixed edge position to a dynamically adjustable position, solving the contradiction between structural simplicity and capture accuracy by allowing the camera to achieve the correct shooting angle through rotation rather than requiring complex mechanical adjustments.
2Device complexity
If the camera module is fixed to capture the user's face, then the terminal structure is simple, but the user cannot see their face on the display unit, making accurate selfie capture difficult
Solution Approach 1:
The patent implements feedback by providing a display unit on the front side of the rotatable second body unit that shows real-time preview images captured by the camera module. This allows users to see their face on the display while the camera is positioned at the correct angle, providing visual feedback for accurate selfie capture. The feedback mechanism eliminates the need for users to manually adjust the terminal direction, as the system automatically provides both the correct camera angle and visual confirmation.
Solution Approach 2:
The patent applies dimensionality change by adding the rotational degree of freedom between the first and second body units. Instead of fixing the camera in a single position, the camera can rotate around the rotating shaft to achieve different shooting angles. This additional dimensional freedom allows the camera to capture the user's face at the appropriate angle while maintaining a simple overall terminal structure.
3Measurement precision
If the camera module is disposed to have a prescribed tilt angle with the mobile terminal, then the selfie capture angle is improved, but the terminal structure becomes more complex
Solution Approach 1:
The patent uses the dynamics principle by implementing a rotatable second body unit connected to the first body unit through a rotating shaft. The camera module disposed on the second body unit can achieve the prescribed tilt angle through rotation rather than requiring complex mechanical tilting mechanisms. This dynamic rotational approach simplifies the overall structure compared to fixed tilt mechanisms while maintaining the ability to capture selfies at the appropriate angle.

AI summary
The present invention relates to a mobile terminal comprising: a first body unit; a second body unit; a display unit; a camera module; and a control unit, wherein when the second body unit rotationally moves toward the first body unit, if the angle between the first body unit and the second body unit is not more than a first angle and not less than a second angle, the control unit operates the camera module to photograph an image, and if the angle between the first body unit and the second body unit is less than the second angle, the control unit stops the image photographing of the camera module, and wherein when returning the second body unit so that the angle between the first body unit and the second body unit is greater than or equal to the first angle, the control unit displays the image photographed by the camera module on the display unit.
