Mobile Terminal Camera Placement for Optical Zoom and 3D Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication terminals face challenges in smoothly capturing optical zoom images, three-dimensional images, accurately measuring distances, and capturing wide-angle or ultrawide-angle images due to limitations in camera placement and distance between cameras.
Innovation Solution
A mobile communication terminal is designed with a main body featuring a display on the front surface, a first camera group on the front surface, a second camera group on the rear surface, and additional cameras placed on different installation surfaces, such as the top or side surfaces, allowing for greater flexibility in image capture and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cameras are disposed only on the front surface and rear surface of the main body, then the device structure is simple, but the terminal cannot smoothly capture optical zoom images, three-dimensional images, or wide-angle images
Solution Approach 1:
The patent applies dimensionality change by disposing cameras not only on the front and rear surfaces (0th dimension) but also on the side surfaces (1st dimension) and top/bottom surfaces (2nd dimension) of the main body. This multi-dimensional camera arrangement enables diverse imaging functions including optical zoom, three-dimensional imaging, and wide-angle imaging without significantly increasing device complexity
Solution Approach 2:
The patent segments the camera system into multiple independent camera modules disposed at different locations on the main body. Each camera module can be independently configured for specific functions (e.g., wide-angle, telephoto, depth sensing), allowing the system to achieve versatile imaging capabilities while maintaining modular and manageable device complexity
2Measurement precision
If the distance between cameras is small, then the device size is compact, but the terminal cannot accurately measure distance or effectively generate three-dimensional images
Solution Approach 1:
The patent utilizes three-dimensional space by disposing cameras on side surfaces and top/bottom surfaces in addition to front and rear surfaces. This spatial segmentation allows cameras to be positioned at optimal distances for accurate depth measurement and three-dimensional image generation while maintaining a compact overall device volume through efficient use of available space
3Adaptability or versatility
If cameras are disposed on multiple installation surfaces, then the terminal can smoothly capture various types of images, but the device structure becomes more complex
Solution Approach 1:
The patent implements multi-functionality by configuring camera modules on multiple surfaces to serve diverse imaging purposes. The same camera hardware disposed at different locations can be used for wide-angle imaging, optical zoom, three-dimensional imaging, and distance measurement, allowing a single camera system to perform multiple functions without requiring separate dedicated modules for each function
