Cropped Scaled Picture-In-Picture Video Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Picture-In-Picture (PIP) systems inefficiently utilize display space by overlaying a secondary video image over a primary image, making it difficult to view details and wasting valuable display area on unwanted parts of the image.
Innovation Solution
A video system that allows for cropping and scaling of either image, merging only portions of the video signals to efficiently utilize display space, such as displaying a real-time stock ticker at the bottom of the screen, and enabling side-by-side or other configurations of video signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the second video image is made smaller to reduce obstruction of the first video image, then the display area utilization is improved, but the viewing detail of the second video image deteriorates
Solution Approach 1:
The patent segments the second video image by cropping it to retain only the most important portions (such as financial data in a news broadcast), eliminating unnecessary parts while preserving critical information. This allows the cropped image to be displayed at a larger size without obscuring the primary video, simultaneously improving display area utilization and maintaining viewing detail of important elements.
Solution Approach 2:
The patent applies local quality by selectively processing different regions of the second video image. Instead of uniformly scaling or cropping the entire image, it identifies and retains only specific regions containing important information (such as text overlays or key visual elements), while discarding less important areas. This enables optimized display where critical details remain visible at appropriate sizes.
2Difficulty of detecting and measuring
If the entire video image is displayed to maintain viewing detail, then the viewing detail is improved, but the display area utilization deteriorates due to unwanted parts
Solution Approach 1:
The patent extracts only the essential portions from the second video image based on predefined criteria (such as retaining images with text overlays or specific visual characteristics). By taking out only the necessary parts and discarding unwanted portions, the system maximizes display area utilization while preserving the viewing detail of important elements through selective retention rather than complete image display.
3Difficulty of detecting and measuring
If the second video image is displayed at full size to maintain viewing detail, then the viewing detail is improved, but the obstruction of the first video image increases
Solution Approach 1:
The patent applies partial action by displaying only the necessary portions of the second video image rather than the complete image. By using partial cropping and selection based on image characteristics (such as detecting text content or important visual elements), the system reduces the obstructed area of the first video image while maintaining sufficient viewing detail of the second image's critical information.

AI summary
We describe a cropped and scaled picture-in-picture system and method. The video system includes a first video port to generate a first video signal portion from a first video signal, a second video port to generate a second video signal portion from a second video signal, and a video processor to generate a composite image from the first and second video signal portions.
