HDR Image Processing Method for Non-HDR Display Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Images or videos in high dynamic range (HDR) format cannot be properly displayed on devices that do not support HDR, resulting in degraded image quality, such as reduced brightness.
Innovation Solution
An image processing method that detects whether an image source is HDR or non-HDR, reads specific adjustment values (brightness, contrast, saturation, hue) to perform color adjustments, and converts HDR images to non-HDR if the display device does not support HDR, ensuring optimal display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If HDR image processing is performed on non-HDR display devices, then image quality is improved, but device compatibility is reduced
Solution Approach 1:
The patent applies parameter changes by detecting whether the image source is HDR or non-HDR format and dynamically adjusting processing parameters accordingly. When an HDR image is detected on a non-HDR device, the system converts the HDR format to non-HDR format and applies specific color adjustment parameters (first image adjustment value) to maintain image quality. This resolves the contradiction by adapting the processing parameters to match the device capabilities while preserving image quality through format conversion and targeted color adjustment.
2Productivity
If color adjustment is performed without detecting image type, then processing speed is improved, but image accuracy deteriorates
Solution Approach 1:
The patent implements preliminary action by detecting the image source type (HDR or non-HDR) before performing color adjustment processing. The system reads the appropriate adjustment values based on the detected image type and performs the conversion and color adjustment in advance before display. This preliminary detection and preparation ensures that the correct processing path is selected upfront, maintaining both processing efficiency and image accuracy by avoiding reprocessing or incorrect adjustments.
Data Source
AI summary
An image processing method includes receiving an image source, and detecting whether the image source is a high dynamic range (HDR) image. If the image source is the HDR image, reading a first image adjustment value, and performing color adjustment to the image source according to the first image adjustment value.
