Image Display Device Size-Based Quality Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image quality adjustment methods for specific colors, such as skin color, struggle when parts of the face are hidden by masks or sunglasses, leading to inadequate correction due to reduced pixel counts, resulting in suboptimal image quality.
Innovation Solution
An image display device and method that detect a predetermined object, such as a face, and adjust image quality based on its size rather than pixel count, using an object detector, size acquirer, determiner, image quality adjuster, and display controller to ensure proper image quality adjustment even when the object is partially obscured.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of pixels of a specific color is used to determine correction, then the correction can be performed when the face occupies a large area, but the correction fails when the face is partially hidden or blurred
Solution Approach 1:
The patent changes the determination parameter from pixel count to object size. Specifically, it uses the size of the detected face object (obtained through object detection and size acquisition) as the basis for determining whether to perform image quality adjustment, rather than relying on the count of skin-color pixels. This parameter change ensures reliable correction regardless of whether the face is partially hidden or blurred, as object detection can identify the face as a whole entity even when parts are occluded.
2Device complexity
If pixel count method is used, then the processing is simple, but the accuracy of determining when to adjust image quality deteriorates
Solution Approach 1:
The patent introduces an object detection module as an intermediary between image acquisition and image quality adjustment. This intermediary detects the face object and provides size information, which then serves as the basis for determining whether to perform correction. This intermediary step improves determination accuracy by providing more reliable object-based measurements while maintaining reasonable processing complexity through automated detection algorithms.

AI summary
An image display device includes an image acquirer that acquires an input image, an object detector that detects a predetermined object from the input image, a size acquirer that acquires a size of the predetermined object, a determiner that determines whether to adjust an image quality for a specific color of the predetermined object based on the size of the predetermined object, an image quality adjuster that adjusts the image quality of at least a partial region of the input image for the specific color, and a display controller that controls a display panel to display the input image having the image quality adjusted.
