Display Apparatus Automatic HDR SDR Image Quality Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses require users to manually set and adjust image quality settings for HDR and SDR comparisons, which is time-consuming and cumbersome, especially when comparing image qualities before and after correction using CDL.
Innovation Solution
A display apparatus with a memory that stores conversion correspondences to automatically generate image signals of different qualities, allowing for easy comparison of HDR and SDR images by performing luminance conversions or using lookup tables, and determining the necessary image processing based on input signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual setting of image quality parameters is performed for each region, then accurate HDR/SDR comparison display is achieved, but operation time and complexity increase significantly
Solution Approach 1:
The display apparatus automatically detects the input signal type (HDR or SDR) and autonomously configures the appropriate image quality parameters for each region without requiring manual user input. The system serves itself by automatically setting luminance, color gamut, and gamma values based on the detected signal characteristics, thereby eliminating time-consuming manual operations while maintaining accurate HDR/SDR comparison display
Solution Approach 2:
The system dynamically changes image quality parameters (luminance, color gamut, gamma) based on the detected input signal type. When HDR signal is detected, the system automatically configures HDR-appropriate parameters; when SDR signal is detected, it configures SDR-appropriate parameters. This automatic parameter adjustment enables accurate comparison display without manual intervention
2Adaptability or versatility
If multiple image quality settings are manually configured for different regions, then comprehensive image quality comparison is enabled, but device complexity and operation difficulty increase
Solution Approach 1:
The apparatus automatically detects whether the input signal is HDR or SDR and self-configures the appropriate display parameters for each region. This self-service mechanism eliminates the need for users to manually understand and configure multiple image quality parameters, making the operation simple while maintaining comprehensive HDR/SDR comparison capability
Solution Approach 2:
The display apparatus integrates multiple functions into a single automated process: signal detection, parameter determination, and display configuration. This multi-functional approach allows the system to handle both HDR and SDR comparisons uniformly through automatic detection and configuration, simplifying user interaction while maintaining versatility

AI summary
A display apparatus, comprising: a memory that stores correspondence to convert an image quality of an image signal; and at least one processor that operates as: an input unit that inputs a first image signal having a first image quality; a generation unit; and a display unit that displays the first image signal and the image signal generated by the generation unit, wherein in the case of the memory storing correspondence to generate a second image signal having a second image quality from the first image signal, the generation unit generates the second image signal from the first image signal in accordance with the correspondence, and in the case of the memory not storing the correspondence to generate the second image signal from the first image signal, the generation unit generates a third image signal by performing a predetermined luminance conversion on the first image signal.
