Image Processing Device for Automatic Channel Sorting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
General-purpose reproduction equipment cannot effectively separate and view video pictures from multiple channels due to differing specifications in recognizing frame channels, making it impossible to reproduce video pictures for each channel independently.
Innovation Solution
An image processing device with an automatic sorting unit that calculates the similarity degree of frames within a moving image and sorts them into channels based on this similarity, using techniques such as dividing frames into sub-regions, detecting feature points, and calculating local and total similarity degrees to accurately determine channel affiliation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If general-purpose reproduction equipment is used to play back mixed-channel moving images, then compatibility and ease of operation are improved, but the ability to separate and reproduce video pictures for each channel is lost
Solution Approach 1:
The patent applies preliminary action by embedding channel identification information (channel number data) into the video frames during the recording phase. This allows general-purpose reproduction equipment to later identify and separate channels without requiring specialized hardware, resolving the contradiction between ease of operation and channel separation capability.
2Adaptability or versatility
If dedicated equipment with channel number data is used, then channel separation and reproduction for each channel is achieved, but device complexity and cost increase
Solution Approach 1:
The patent uses copying by embedding channel identification data as metadata within the video stream itself, rather than requiring separate physical channels or complex dedicated equipment. This allows standard reproduction devices to access channel information through simple data parsing, reducing device complexity while maintaining channel separation capability.
3Reliability
If specifications for recognizing channel differ between manufacturers, then device-specific optimization is achieved, but interoperability and universal reproduction capability are worsened
Solution Approach 1:
The patent implements universality by using a standardized channel identification method that can be universally recognized across different manufacturers' equipment. The channel number data is embedded in a format that works with general-purpose reproduction equipment regardless of manufacturer, ensuring both reliable channel recognition and cross-platform compatibility.

AI summary
Provided is an image processing device for sorting frames included in one moving image into different channels, the frames included in the moving image being a mixture of frames belonging to the different channels. The image processing device includes an automatic sorting unit. The automatic sorting unit calculates a similarity degree of the plurality of frames included in the moving image by performing image processing on the frames, and sorts the plurality of frames into the plurality of channels based on the similarity degree.
