Pointer-Based Sub Screen Selection in Picture-in-Picture Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing apparatuses with picture-in-picture (PIP) functions are inconvenient for users to select images for the sub screen, as the sub screen is smaller and overlapping with the main screen, making it difficult to recognize and select content, especially subtitles, and requires navigating through menus.
Innovation Solution
An image processing apparatus and control method that allows users to easily select a desired image for the sub screen by adjusting a pointer to select at least two points, setting a boundary, and displaying the selected image on a predetermined region, ensuring the image remains visible even when the input video signal changes, using a pointer adjuster and controller to manage the display and processing of multiple video signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a menu is used to select video signals for the sub screen, then the PIP function can be implemented, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The patent replaces the menu-based selection system (information field) with a direct pointer-based selection system on the display screen itself. Users can directly point to and select regions on the main screen to create sub screens, eliminating the need to navigate through menus and making the selection process more intuitive and efficient.
2Adaptability or versatility
If the sub screen is displayed at a predetermined region overlapping the main screen, then PIP function is achieved, but the sub screen becomes too small for easy recognition of content
Solution Approach 1:
The patent makes the sub screen dynamic by allowing users to freely adjust its size and position on the display screen. Instead of being fixed at a predetermined region, the sub screen can be resized and repositioned to optimal locations, enabling users to balance between displaying multiple channels and maintaining adequate image size for recognition.
3Adaptability or versatility
If the sub screen displays a fixed image, then the PIP function works, but the image becomes invisible or outdated when the input video signal changes
Solution Approach 1:
The patent implements automatic detection and updating mechanisms that monitor changes in the main screen content. When the input video signal changes or new content appears on the main screen, the system automatically detects these changes and updates the sub screen accordingly, ensuring the sub screen always displays relevant and current information without requiring manual intervention.

AI summary
An image processing apparatus includes: a display which displays an image through at least one screen; a processor which processes the image to be displayed on the display; a pointer adjuster which adjusts a pointer to select at least two points on the image displayed on the display; and a controller which sets a selection area by selecting a partial image displayed within a boundary including the at least two points from the image displayed on the display, and controls the processor to display the selection area on a predetermined region of the display.
