Image Display Apparatus Thumbnail Browsing via Device Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in intuitively identifying contents of video signals across multiple channels in digital broadcasting, leading to time-consuming channel switching.
Innovation Solution
An image display apparatus and method that generates thumbnail images based on input signals, allowing for the display of multiple thumbnail lists with different numbers and sizes, enabling intuitive channel browsing by pivoting the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If users switch through available channels one by one to identify broadcasting programs, then users can find out what programs are about, but it takes much time
Solution Approach 1:
The system performs preliminary action by generating and displaying thumbnail images of broadcasting programs on multiple channels simultaneously before the user makes a channel selection. This allows users to preview program contents across channels in advance, eliminating the need to switch through each channel sequentially to identify program information.
Solution Approach 2:
The system creates simplified copies (thumbnails) of the actual broadcasting content from multiple channels and displays them together on the main screen. These thumbnail copies provide sufficient visual information for users to identify program contents without needing to view the full channel content or switch channels.
2Ease of operation
If the display screen is divided into multiple areas to show both main image and thumbnail lists, then users can browse channels without interrupting the main image, but the area for displaying thumbnail images is reduced
Solution Approach 1:
The system utilizes the temporal dimension by allowing users to switch between different display modes (full screen, split screen with thumbnails, picture-in-picture) depending on their browsing needs. This dimensional approach to display management allows the thumbnail display area to be dynamically adjusted without permanently reducing the main image area.
Solution Approach 2:
The display configuration is made dynamic rather than static. The system can automatically or manually adjust the size and position of thumbnail areas based on user interaction, allowing the thumbnail display area to expand when browsing is needed and contract when full-screen viewing is preferred, optimizing both browsing capability and image display area at different times.

AI summary
A display method of an image display apparatus that includes receiving a broadcast signal, displaying a first number of thumbnail images when the image display apparatus is in a first position (the thumbnail images being based on the received broadcast signal), rotating the image display apparatus from the first position to a second position, and displaying a second number of thumbnail images when the image display apparatus is rotated to the second position, and the second number is different than the first number.
