Imaging Control Apparatus for Automatic Face Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image capturing devices, including smartphones, face challenges in taking selfies due to the difficulty in previewing and manually adjusting the camera to capture human faces, especially when taking videos, and the front camera often produces low-resolution images.
Innovation Solution
An imaging method and apparatus that determine a target position for a human face in the imaging frame, output capturing instructions, detect the face, and control a positioning mechanism to move the image capturing mechanism to position the face at the target location, improving the ease and quality of selfie capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the front camera is used to take selfies, then the ease of operation is improved, but the manufacturing precision (image resolution) deteriorates
Solution Approach 1:
The system performs preliminary face detection and positioning calculations before capturing the image. The processor detects the human face in the captured scene and calculates the positioning instruction in advance, then controls the positioning mechanism to adjust the image capturing mechanism before the actual capture, ensuring the face is properly positioned in the imaging frame
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated electronic control system. The processor automatically generates positioning instructions based on face detection results and controls the positioning mechanism electronically, eliminating the need for users to manually adjust the camera while maintaining high image quality
2Manufacturing precision
If the rear camera is used to take selfies, then the manufacturing precision (image resolution) is improved, but the ease of operation deteriorates due to inability to pre-view
Solution Approach 1:
The system enables the image capturing device to serve itself by automatically detecting the face, calculating the positioning instruction, and adjusting the positioning mechanism without user intervention. The processor performs all necessary operations including face detection, position calculation, and control signal generation, making the system self-sufficient and eliminating the need for manual adjustment
3Ease of operation
If a rotatable pre-view screen is added, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent replaces the mechanical rotatable screen mechanism with an electronic positioning system. Instead of physically rotating the screen to show the user their reflection, the system uses the positioning mechanism to automatically adjust the camera angle, capturing the user's face directly in the imaging frame without requiring screen rotation or manual adjustment

AI summary
An imaging method includes determining a target position in an imaging frame of an image capturing mechanism connected with a positioning mechanism, outputting a capturing instruction to control the image capturing mechanism to capture a scene including a human face after the target position is determined, detecting the human face from the captured scene, and outputting a control instruction to position the detected human face at the target position by moving the positioning mechanism to move the image capturing mechanism.
