Rotating Lens Module Camera Control for Intuitive Framing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face cumbersome and non-intuitive operations when adjusting the position of a target object in a preview image on electronic devices with cameras, requiring constant adjustments of the device's position during shooting.
Innovation Solution
A control method and apparatus that displays a preview image, receives user input to adjust the display position of a target object, and adjusts the camera's shooting angle accordingly, allowing for intuitive and real-time positioning of the object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user constantly adjusts the position of the electronic device during shooting, then the target object can be positioned at the expected location in the picture, but the operation becomes cumbersome and non-intuitive
Solution Approach 1:
Instead of moving the electronic device to reposition the target object in the picture (traditional approach), the patent inverts the control logic by moving the camera's field of view through lens rotation while keeping the device body stationary. This allows users to adjust the target position by rotating the lens module, providing a more intuitive and less cumbersome operation
Solution Approach 2:
The patent segments the electronic device into independent modules: a stationary device body and a rotatable camera module with lens. This segmentation allows the camera module to be independently rotated to adjust shooting angles without requiring the entire device to be moved, simplifying the operation while maintaining positioning accuracy
2Ease of operation
If the camera shooting angle is adjusted in real-time based on user input, then the target object positioning becomes more intuitive and convenient, but the control system complexity increases
Solution Approach 1:
The patent implements real-time feedback by continuously updating the preview image on the display screen as the lens module rotates. Users can see the effect of their rotation adjustments immediately, allowing for intuitive and convenient camera control while the system automatically processes the positioning information
Solution Approach 2:
The patent introduces a processor as an intermediary that receives user input, calculates the required lens rotation angle, controls the motor to rotate the lens module, and updates the preview image. This intermediary layer manages the control system complexity by automating the coordination between user input and physical camera adjustments

AI summary
A control method includes: a preview image is displayed; a user input acting on the preview image is received, in which the user input includes an adjustment of a display position of a target object in the preview image from a first position to a second position; and in response to the user input, a shooting angle of the camera is adjusted according to the adjustment of the display position.
