Display Control for Selective Subject Blur in Shared Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to control the display state of subjects in shared images, leading to unintended sharing of private or confidential information during online meetings and video distributions.
Innovation Solution
A display control apparatus and method that detects regions of objects within a captured image, allowing users to control the display manner of these objects in response to triggers such as user instructions, audio, or actions, enabling selective hiding or blurring of unwanted subjects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If camera focus control is used to highlight target objects, then the visibility of target objects is improved, but unintended subjects within the depth of field are also clearly displayed, compromising privacy protection
Solution Approach 1:
The patent applies different display treatments to different regions of the image. The target object region is kept clear and focused, while unintended subject regions within the depth of field are selectively blurred or obscured. This local differentiation allows the target object to remain visible while protecting privacy of unintended subjects, resolving the contradiction between target visibility and privacy protection.
2Object-affected harmful factors
If mosaic processing is applied to protect privacy after shooting, then privacy protection is achieved, but the processing cannot be dynamically adjusted during real-time video streaming
Solution Approach 1:
The patent implements dynamic display control that can be adjusted in real-time during video streaming. The display control unit can change the blur level, apply mosaic processing, or switch between different privacy protection modes based on real-time detection of unintended subjects and user preferences. This dynamic adaptability allows privacy protection to be flexibly adjusted during live streaming, resolving the contradiction between privacy protection and real-time control flexibility.
3Quantity of substance
If all subjects within the angle of view are captured, then comprehensive scene documentation is achieved, but private or confidential information of unintended subjects is also shared
Solution Approach 1:
The patent segments the image into different subject regions and applies different processing to each segment. The detection unit identifies multiple subjects including unintended ones, and the display control unit selectively processes only the unintended subject regions with blur or mosaic effects while leaving other regions unchanged. This segmentation approach allows comprehensive scene documentation while preventing unintended information sharing, resolving the contradiction between capturing all subjects and protecting privacy.

AI summary
A display control apparatus detects a region of an object that is a subject different from a predetermined subject in a captured image including the predetermined subject, and causes a display unit to display an image in which a display manner of the object is controlled with respect to a region of the object in the image. The display control apparatus controls, in response to detection of a trigger for switching a display manner of the object while sequentially acquiring captured images, a display manner of the object to a display manner corresponding to the trigger.
