Video Overlay Transparency Control for Human Gesture Explanations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image superimposition technologies struggle to maintain clarity of background images when superimposing information on human bodies performing explanatory gestures, leading to difficulty in understanding the superimposed information.
Innovation Solution
An information processing apparatus that extracts human regions from images, determines if the human is performing an explanatory action, and adjusts the transparency of overlapping superimposition information based on these regions to enhance visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If superimposition information is overlaid on the entire human body region, then the information is always visible, but the background image becomes difficult to see when the human performs explanatory gestures
Solution Approach 1:
The patent applies different transparency settings to different regions of the superimposed information based on whether they overlap with the human body. Specifically, regions overlapping with the human body maintain normal transparency for consistent visibility, while regions not overlapping with the human body adjust transparency based on the detected action type (higher transparency for explanatory actions, lower for non-explanatory actions). This local differentiation resolves the contradiction by making the background more visible during explanatory gestures in non-overlapping regions while preserving information visibility in overlapping regions.
Solution Approach 2:
The patent dynamically adjusts the transparency of superimposed information based on real-time detection of human actions. The system detects whether the human is performing an explanatory action or a non-explanatory action and changes the transparency accordingly. For explanatory actions, transparency increases in non-overlapping regions to prioritize background visibility; for non-explanatory actions, transparency decreases to prioritize information visibility. This dynamic adjustment resolves the contradiction by adapting to the contextual needs of different action types.
2Loss of information
If transparency of superimplied information is increased to improve background visibility, then the background becomes easier to see, but the superimplied information becomes harder to understand
Solution Approach 1:
The patent applies different transparency settings to different regions of the superimposed information. Regions that overlap with the human body maintain normal transparency regardless of action type, ensuring information remains clearly visible and understandable. Only regions that do not overlap with the human body have their transparency dynamically adjusted. This spatial differentiation ensures that information understandability is preserved in critical overlapping regions while background clarity is improved in non-critical non-overlapping regions.
Solution Approach 2:
The patent dynamically adjusts transparency based on detected action types, but only for non-overlapping regions. When explanatory actions are detected, transparency increases in non-overlapping regions to improve background visibility. When non-explanatory actions are detected, transparency decreases in non-overlapping regions to improve information visibility. Overlapping regions maintain consistent transparency throughout. This conditional dynamic adjustment resolves the contradiction by applying transparency changes only where they do not compromise information understandability.

AI summary
An information processing apparatus that makes it possible to see information in an easily understandable manner when this information is superimposed onto a video image has at least one memory and at least one processor. The at least one memory and the at least one processor are configured to extract a region of a human in an image; superimpose predetermined superimposition information onto the image; determine whether or not the human is performing a predetermined action, and to output determination results; extract a region of the predetermined information that overlaps with the region of the human as an overlapping region based on the determination results, the region of the human, and the predetermined information; and change a transparency of at least a portion of the predetermined information such that the transparency increases according to the overlapping region.
