Composite Video Side Alignment Using Local Search Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video processing systems require users to manually align multiple input videos one by one, which is time-consuming and burdensome, especially when aligning sides of horizontally or vertically arranged content.
Innovation Solution
A video processing apparatus that identifies and aligns sides near a specified position by forming a search range around the specified point, allowing for easy alignment of sides with the same or similar angles, and maintains aspect ratios to prevent distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual alignment of multiple input videos is performed using traditional video mixers, then alignment precision can be achieved, but the operation time and user effort increase significantly
Solution Approach 1:
The system performs automatic alignment by detecting sides of video content and computing alignment transformations without requiring manual user intervention for each video element, thereby achieving precise alignment while significantly reducing operation time
Solution Approach 2:
The system transforms video content by applying geometric transformations (translation, rotation, scaling) based on detected side parameters and angle measurements, enabling automatic alignment while maintaining aspect ratios and preventing distortion
2Manufacturing precision
If traditional video mixing operations are used to align video positions, then alignment can be achieved, but the operational complexity and user burden increase
Solution Approach 1:
The alignment system automatically detects video content boundaries, calculates side angles, and determines optimal alignment transformations without requiring users to manually adjust each video element, thereby maintaining high alignment accuracy while dramatically reducing user effort
Solution Approach 2:
The system replaces manual mechanical adjustment operations with automated computational geometry algorithms that detect side lines, compute angles, and apply transformations programmatically, eliminating the need for users to familiarize themselves with complex mixer operations
3Manufacturing precision
If video content is resized or repositioned to achieve alignment, then alignment can be achieved, but video distortion may occur
Solution Approach 1:
The system applies geometric transformations (translation, rotation, and uniform scaling) that maintain the aspect ratio of video content while achieving precise alignment, thereby avoiding distortion by carefully controlling transformation parameters
Solution Approach 2:
This principle is not applicable to this patent as the solution does not involve pneumatic or hydraulic mechanisms

AI summary
Provided are a video processing apparatus that is capable of easily aligning sides near a specified position among the sides of contents arranged in a composite video, a computer-readable recording medium recording a video processing program, and a video processing method. In a video switcher 1, a specified position specified in a composite video Sc by a user H via touch panels 3a and 4a is acquired, and a search range Se is formed based on the specified position. The sides of contents C1 to C3 included in the search range Se are identified as specific sides Ss, and the identified specific sides Ss are aligned. Thus, the user H is allowed to easily align the sides near the specified position, among the sides of the contents C1 to C3 arranged in the composite video Sc, by simply specifying the specified position in the composite video Sc.
