Stereoscopic Video Depth Adjustment for Scene Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Viewers experience fatigue due to sudden changes in perceived depth during scene switching in stereoscopic videos, as existing techniques are not applicable to scene switching within stereoscopic videos.
Innovation Solution
A stereoscopic video processing apparatus and method that detects scene changes and adjusts perceived depth by inserting two-dimensional frames and perceived depth adjusting frames to ensure gradual changes in depth perception, using video input and scene detection to manage the display of stereoscopic videos.

1Productivity
If scene changes occur in stereoscopic videos, then the content transitions to new scenes, but the perceived depth changes suddenly causing viewer fatigue
Solution Approach 1:
The system performs preliminary detection of scene changes and pre-calculates the required number of adjusting frames before actual scene transition. This allows the depth adjustment process to be prepared in advance, ensuring smooth transitions without sudden depth changes that cause viewer fatigue.
Solution Approach 2:
The scene transition process is segmented into multiple phases: detection phase, calculation phase, and execution phase with interpolated adjusting frames. By dividing the transition into discrete adjustable steps rather than a single abrupt change, the system eliminates sudden depth shifts while maintaining efficient scene changes.
2Object-affected harmful factors
If the number of perceived depth adjusting frames is increased, then the perceived depth changes more gradually reducing viewer fatigue, but the playback time increases
Solution Approach 1:
The system dynamically determines the number of perceived depth adjusting frames based on the actual depth difference between consecutive scenes. When depth difference is large, more adjusting frames are inserted; when depth difference is small, fewer adjusting frames are used. This dynamic adaptation ensures gradual depth changes to reduce viewer fatigue while avoiding unnecessary playback time extension.
Solution Approach 2:
The system changes the parameter of frame insertion quantity based on the measured depth difference between scenes. By adjusting this parameter dynamically, the system optimizes the balance between smooth depth transitions (reducing viewer fatigue) and playback time efficiency, avoiding fixed excessive frame insertion.
3Object-affected harmful factors
If scene changes are detected and processed, then the perceived depth can be adjusted gradually, but the processing complexity increases
Solution Approach 1:
The system uses the existing scene detecting means already present in the video playback apparatus to identify scene changes. By leveraging this existing self-service capability rather than requiring an entirely new detection system, the patent reduces processing complexity while still achieving gradual perceived depth adjustment to minimize viewer fatigue.
Solution Approach 2:
The scene detecting means serves multiple functions: it detects scene changes for content transition and simultaneously provides the basis for depth adjustment processing. This multi-functionality reduces overall system complexity by reusing existing components rather than adding separate dedicated systems.

AI summary
A stereoscopic video processing apparatus is constituted by: a video input section, for receiving input of stereoscopic videos constituted by a plurality of frames, which are viewable stereoscopically; a scene detecting section, for detecting positions within the stereoscopic videos at which scene changes occur; and a perceived depth adjusting section, for administering perceived depth adjusting processes that adjust the perceived depths of the stereoscopic videos such that the perceived depth changes gradually at the positions at which scene changes occur.
