Image Display Definition Control via Visual Pattern Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to set desired definition settings on image display devices due to the need for repetitive controls and lack of specific knowledge about definition manipulation, leading to inefficient control of brightness, contrast, color, and sharpness.
Innovation Solution
A method and device that display two patterns on the screen, allowing users to easily control definition by matching the state of a first pattern to a second pattern with standard definition, using a control value to adjust the first pattern while keeping the second pattern fixed, and providing an On Screen Display (OSD) with variable and fixed regions to facilitate intuitive control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually adjust definition settings using control bars, then definition can be changed, but repetitive controls are required and users lack specific knowledge leading to difficulty in setting desired definition
Solution Approach 1:
The screen is divided into multiple pattern regions (first pattern region, second pattern region, third pattern region) displaying different definition characteristics. Users can selectively control specific pattern regions rather than adjusting all settings uniformly, reducing the complexity and time of repeated controls.
Solution Approach 2:
The patent uses reference patterns (second pattern) that represent standard definition characteristics. Users adjust the first pattern by comparing it with the reference pattern, eliminating the need to memorize specific control values or perform repeated adjustments to achieve desired definition settings.
2Ease of operation
If users manually adjust definition settings, then definition can be changed, but users lack specific knowledge of definition manipulation
Solution Approach 1:
The patent displays reference patterns that embody standard definition characteristics. Users can visually compare the first pattern with the reference pattern to understand the effect of their adjustments, eliminating the need to possess specific technical knowledge about definition manipulation while still achieving accurate settings.
Solution Approach 2:
The patent provides visual feedback by displaying multiple pattern regions with different definition characteristics simultaneously. Users receive immediate visual information about the effect of their controls, allowing them to adjust settings intuitively without needing prior knowledge of definition parameters.
3Ease of operation
If control value display OSD is added to show input control value, then user feedback is improved, but device complexity increases
Solution Approach 1:
The control value display OSD is merged with the existing pattern display regions. The OSD is integrated into the screen structure, sharing the same display hardware and control mechanisms, thereby providing user feedback without adding separate physical components or significantly increasing device complexity.

AI summary
A definition control method and an image display device using the same are provided. The definition control method includes displaying a first pattern and a second pattern, inputting a control value, and changing a display state of the first pattern according to the input control value, wherein a display state of the second pattern is not changed by the control value.
