Image Editing Apparatus Selective Masking for Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies fail to effectively protect privacy and portrait rights in moving images shared on networks without degrading the original image quality when exhibited to a large number of unspecified people.
Innovation Solution
An image editing apparatus that extracts specific subjects from moving images and applies minimal necessary mask processing based on output resolution, determining whether to perform mask processing on objects such as faces or vehicles to protect privacy and portrait rights without degrading image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mask processing is applied to protect privacy and portrait rights in moving images, then privacy protection is improved, but image quality and details are degraded
Solution Approach 1:
The patent applies mask processing selectively only to specific subjects (people, vehicles, animals) identified through subject extraction, rather than applying uniform processing to the entire image. This localized approach protects privacy where needed while preserving image quality in other areas.
Solution Approach 2:
The patent determines whether mask processing is necessary based on output resolution thresholds. When the output resolution is below a predetermined threshold, mask processing is applied; when above the threshold, processing is omitted. This partial application of processing protects privacy in low-resolution outputs while avoiding quality degradation in high-resolution outputs.
2Reliability
If mask processing is applied to all subjects in moving images, then privacy protection is improved, but image quality is excessively degraded
Solution Approach 1:
The patent applies mask processing selectively only to specific subjects (people, vehicles, animals) identified through subject extraction, rather than applying uniform processing to the entire image. This localized approach protects privacy where needed while preserving image quality in other areas.
Solution Approach 2:
The patent determines whether mask processing is necessary based on output resolution thresholds. When the output resolution is below a predetermined threshold, mask processing is applied; when above the threshold, processing is omitted. This partial application of processing protects privacy in low-resolution outputs while avoiding quality degradation in high-resolution outputs.
3Reliability
If image processing is performed to protect privacy in moving images, then privacy protection is improved, but processing complexity increases
Solution Approach 1:
The patent performs subject extraction and determines the necessity of mask processing in advance based on output resolution conditions. By pre-determining which subjects require masking and whether processing is necessary, the system simplifies the overall processing workflow and reduces computational complexity during actual image rendering.
Solution Approach 2:
The patent determines whether mask processing is necessary based on output resolution thresholds. When the output resolution is below a predetermined threshold, mask processing is applied; when above the threshold, processing is omitted. This partial application of processing reduces overall processing complexity while maintaining adequate privacy protection.

AI summary
An image editing apparatus includes an input unit configured to input a moving image stream that includes a plurality of frames, an extracting unit configured to extract a specific subject from at least one of frames included in the input moving image stream, and an image processor configured to determine whether or not to perform a mask processing to the specific subject included in the at least one frame of the input moving image stream according to a predetermined output condition which is defined based on at least an output resolution of the moving image stream to be output, and performs the mask processing to the specific subject based on the determination result.
