Stereoscopic Time Code Display Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in visually recognizing agreement or disagreement between time codes of left and right images in stereoscopic images, especially when displayed on a monitor, and existing techniques struggle to highlight differences in real-time frame synchronization.
Innovation Solution
A time code display device that extracts and compares left and right image time codes, determining display methods based on agreement or disagreement, with time codes displayed in different manners when they differ, allowing for easy visual recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If time codes of left and right images are displayed simultaneously in the same manner, then the display is simple and unified, but the user cannot visually recognize differences between the time codes in real time
Solution Approach 1:
The patent applies color changes to time code display by changing the luminance (brightness) of displayed time codes based on synchronization status. When time codes are synchronized, they are displayed in a first luminance state; when desynchronized, they are displayed in a second luminance state that differs from the first, enabling visual detection of time code differences through luminance variation.
Solution Approach 2:
The patent changes display parameters (luminance/brightness) of time codes dynamically based on synchronization comparison results. The display device adjusts the luminance parameter of time codes to indicate whether left and right image time codes match, allowing users to visually detect synchronization status through parameter variation.
2Device complexity
If time codes are displayed without comparison indication, then the display method is straightforward, but the user cannot easily recognize agreement or disagreement between time codes
Solution Approach 1:
The patent implements feedback by comparing time codes of left and right images and providing visual feedback through luminance changes. The display device continuously monitors time code synchronization and adjusts the luminance of displayed time codes based on comparison results, giving users immediate visual feedback about synchronization status without adding complex display methods.
3Productivity
If time codes are synchronized beforehand in image signals, then the output is streamlined, but differences between time codes may occur during reproduction without user recognition
Solution Approach 1:
The patent performs preliminary comparison action by comparing time codes of left and right images before final display. The display device compares time codes and determines synchronization status in advance, then adjusts luminance accordingly, ensuring reliable detection of time code differences before they affect reproduction quality.

AI summary
A time code display device includes a time code extraction unit that extracts a left image time code from a left image signal that constitutes a stereoscopic image and a right image time code from a right image signal that constitutes the stereoscopic image; a time code comparison unit that compares the left image time code with the right image time code and outputs a comparison result including information on agreement or disagreement between the left and right image time codes; and a display determination unit that determines to display the left and right image time codes in the same manner when the comparison result indicates agreement therebetween, determines to display the left and right image time codes in different manners when the comparison result indicates disagreement therebetween, and displays the left and right image time codes on a display unit.
