Display Apparatus Using Color Metadata for Handwritten Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses, particularly those using electronic paper, struggle to identify and distinguish handwritten data drawn in different colors, as they convert color information into black-and-white density, making it difficult to highlight or emphasize specific data.
Innovation Solution
A display apparatus that associates handwritten data with color information, allowing it to be identified and displayed with line types corresponding to the original color, even when converted to black-and-white, and includes metadata for color information in files for accurate representation across different devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic paper converts color information into black-and-white density for display, then the display apparatus can show content on black-and-white screens, but the handwritten data cannot be identified or distinguished by its original color
Solution Approach 1:
The patent applies preliminary action by embedding color information metadata into the handwritten data before transmission to black-and-white display devices. This allows the color information to be preserved in the data structure even though the display device itself cannot show colors, enabling downstream color-capable devices to reconstruct the original color representation.
Solution Approach 2:
The patent transitions from a two-dimensional black-and-white display to a three-dimensional data structure that includes color information metadata. By adding this extra dimension of color data to the handwritten content, the system enables color representation on color-capable devices while maintaining compatibility with black-and-white displays.
2Ease of operation
If color information is converted to black-and-white density, then black-and-white display devices can render the content, but the ability to highlight or emphasize specific data by color is lost
Solution Approach 1:
The system performs preliminary action by embedding color information metadata that preserves highlighting capability in the data structure. This allows color-capable devices to later restore the highlighting function, while black-and-white devices can still render the basic content without being hindered by the additional metadata.
Solution Approach 2:
The color information metadata acts as an intermediary that carries highlighting information between the handwritten input and various display devices. This intermediary data structure allows the highlighting capability to be preserved and transmitted, even though black-and-white displays cannot directly render it.
3Adaptability or versatility
If handwritten data is transmitted without color information metadata, then file compatibility is improved, but color representation cannot be accurately preserved across different devices
Solution Approach 1:
The patent applies universality by creating a metadata structure that serves multiple functions: it preserves color information for color-capable devices, maintains compatibility with black-and-white displays, and enables accurate color representation across different device types. This universal data structure adapts to various display capabilities without sacrificing color accuracy where possible.
