Caption Overlap on Image Regions for Screen Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content data display devices on mobile terminals face challenges in effectively utilizing limited screen space and achieving high operability for displaying caption data alongside image data, particularly when dealing with multiple languages, leading to increased costs and storage requirements.
Innovation Solution
A content data display device with a storage unit for image and caption data, a display unit for showing image data, and a control unit that allows users to select regions on the image data to overlap corresponding caption data, enabling flexible and efficient use of screen space without requiring dedicated display regions for captions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If caption data is displayed in a separate region from image data, then the display is clear and organized, but the screen space utilization is reduced and operability is lowered
Solution Approach 1:
The patent merges the caption data display with the image data display by allowing caption data to be displayed overlapping on the image data at the same screen region. This integration eliminates the need for separate display regions, thereby maximizing screen space utilization while maintaining ease of operation through contextually relevant positioning of captions near their corresponding image elements.
2Adaptability or versatility
If new image data is generated for translated languages, then the caption can be displayed, but the file size increases and storage/delivery costs rise
Solution Approach 1:
The patent segments the content data into distinct components: image data and caption data. The image data remains in its original form while caption data is stored separately in a structured format that allows multiple language versions to be associated with the same image. This segmentation enables multi-language support without duplicating the image data, thereby controlling file size and storage costs.
Solution Approach 2:
Instead of creating new image data for each language, the patent uses caption data as a lightweight copy/representation of the textual information. The caption data structure allows multiple language translations to be stored efficiently without requiring separate image files for each language, reducing the overall quantity of data that needs to be stored and delivered.
3Area of stationary object
If caption data is displayed overlapping on image data, then screen space is effectively utilized, but the display may become cluttered
Solution Approach 1:
The patent applies local quality by allowing caption data to be displayed overlapping on specific regions of the image data where the caption is most relevant, rather than uniformly across the entire image. The display control unit positions captions locally near their corresponding image elements, ensuring that the overlapping display enhances rather than obscures the information, thereby maintaining display clarity while utilizing screen space effectively.

AI summary
It is desired to provide a content data display device having a caption display function which can effectively use the screen of the limited size and achieves a high operability. A content data display device includes: a storage unit configured to store an image data and a content data which includes at least one caption data which respectively corresponds to at least one region on the image data; a display unit configured to display the image data; an input unit configured to select a selected region from the at least one region; and a control unit configured to display a caption data which is one of the at least one caption data and corresponds to the selected region to overlap on the selected region of the image data as a selected caption data.
