3D to 2D Video Mode Switching in Medical Camera Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In medical camera systems, switching from 3D to 2D video display mode is cumbersome, causing delays and impairing user convenience due to the need for manual operation and transmission format changes, which results in temporary loss of visual detail during mode switching.
Innovation Solution
An image processing apparatus and camera system that processes left and right eye images with parallax, allowing seamless switching from 3D to 2D mode without changing the display mode on the monitor side, using a single camera to output high-definition 2D and 3D videos via multiple channels, maintaining 3D mode display settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual operation is performed to switch from 3D to 2D display mode, then display mode switching is achieved, but delay time occurs and user convenience deteriorates
Solution Approach 1:
The system pre-processes and stores both 3D and 2D video signals simultaneously. When mode switching is requested, the pre-prepared 2D signal is immediately output without requiring manual operation or reprocessing, thereby eliminating delay time while maintaining adaptability between display modes.
2Adaptability or versatility
If manual operation is performed to change transmission format, then mode switching is achieved, but operational complexity increases
Solution Approach 1:
The system automatically detects the desired display mode and autonomously switches the transmission format without requiring manual user input. The automatic switching mechanism handles format conversion internally, reducing operational complexity while maintaining format adaptability.
3Adaptability or versatility
If display mode is switched from 3D to 2D, then mode change is achieved, but visual detail is temporarily lost
Solution Approach 1:
The system maintains continuous output of both 3D and 2D video signals simultaneously in parallel channels. When switching from 3D to 2D mode, the transition is seamless without interruption or loss of visual information, as the 2D signal is already prepared and continuously available for immediate display.
4Manufacturing precision
If separate processing is performed for 3D and 2D modes, then mode-specific optimization is achieved, but device complexity increases
Solution Approach 1:
The system divides the video processing into separate parallel channels, with one channel dedicated to 3D signal processing and another channel dedicated to 2D signal processing. Each channel is optimized independently for its specific mode, achieving mode-specific image quality while managing complexity through modular parallel architecture.
