Display Apparatus Object Emphasis Dimming Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display apparatuses primarily focus on maximizing contrast ratios for HDR content, which is insufficient for real-time gaming where specific objects within the image need to be emphasized based on game progress.
Innovation Solution
A display apparatus equipped with an input interface, display panel, memory, and processor that identifies specific objects in an image, adjusts dimming values to increase the brightness of those objects, and controls ambient light generation to enhance visual emphasis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If HDR content is displayed with maximum contrast ratio, then image quality for movies/drama is improved, but adaptability for gaming content with real-time object emphasis is insufficient
Solution Approach 1:
The patent implements dynamic image processing by detecting motion vectors of objects in real-time and dynamically adjusting display parameters (brightness, contrast, saturation) based on the detected motion. This allows the system to adapt to different content types (movies vs. gaming) automatically without requiring complex manual configuration, resolving the contradiction between adaptability and processing complexity.
Solution Approach 2:
The system changes display parameters such as brightness, contrast ratio, and color saturation based on the detected object characteristics and motion vectors. By dynamically adjusting these parameters according to the content type and object movement, the system achieves versatile adaptability while maintaining manageable processing complexity through algorithmic optimization.
2Ease of operation
If specific objects are emphasized by increasing brightness, then user engagement in gaming is improved, but overall image quality balance may be compromised
Solution Approach 1:
The patent applies local quality enhancement by selectively adjusting the brightness and contrast of specific regions containing detected objects while maintaining the overall image balance. The system processes different areas of the image with different parameters based on object detection results, allowing emphasis on gaming objects without compromising the quality of other areas, thus resolving the contradiction between user engagement and image quality balance.
Solution Approach 2:
The system uses motion vector detection as feedback to continuously monitor object movement and adjust display parameters in real-time. This feedback mechanism ensures that brightness enhancement is applied dynamically based on actual object behavior, maintaining image quality balance while maximizing user engagement through responsive visual emphasis.

AI summary
Disclosed is a display apparatus. The display apparatus includes an input interface, a display panel, at least one memory configured to store instructions, and at least one processor configured to execute the instructions to identify an object included in an image corresponding to the image signal, adjust a dimming value of an area of the display panel corresponding to the object so that a brightness of the object is increased, and control the display panel to display the image based on the adjusted dimming value.
