Pre-distorted Image Generation for Jewel Surface Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technology fails to accurately display an image on the surface of a jewel without distortion, as it does not consider the jewel's refractive index, color, and other characteristics, leading to image degradation.
Innovation Solution
An apparatus that generates a distorted image corresponding to the original image, taking into account the jewel's characteristics such as refractive index, color, and thickness, and outputs visible light to display the original image accurately on the jewel's surface by analyzing the correspondence relationship between the original and distorted images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an original image is directly displayed on the surface of a jewel, then the display process is simple, but the image becomes distorted due to the jewel's refractive index and characteristics
Solution Approach 1:
The patent applies preliminary action by pre-distorting the image before display. The image processing apparatus calculates distorted coordinates based on the jewel's refractive index and characteristics, then applies distortion correction in advance. This preliminary processing ensures that when the image is displayed through the jewel, the refraction effects are compensated, resulting in an accurate undistorted image on the surface.
2Measurement precision
If distortion correction is applied using software after image capture, then the captured image can be corrected, but the technology cannot be applied to displaying original images on jewel surfaces and does not consider all jewel characteristics
Solution Approach 1:
The patent applies parameter changes by incorporating multiple jewel-specific parameters into the distortion correction process. The system considers the refractive index, color, thickness, and other optical characteristics of the jewel when calculating the distortion correction. By adjusting the correction parameters based on these jewel-specific properties, the system achieves accurate image display that adapts to different jewel types and characteristics.
3Ease of operation
If the jewel's refractive effects are not considered, then the display process is straightforward, but the image color and clarity are degraded
Solution Approach 1:
The patent applies feedback by using the analyzed correspondence relationship between the original image and the image as seen through the jewel to guide the distortion correction process. The system virtually displays the image through the jewel, analyzes the distorted result, and uses this feedback to iteratively adjust the pre-distortion parameters until the final displayed image matches the original image quality and color accuracy.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the generation of an image identical to the original on the jewel's surface, maintaining the original image's color and clarity by compensating for the jewel's refractive effects, thus enhancing the aesthetic appeal of jewelry products.
Implementation Method 1
a jewel is subjected to a phenomenon in which light is transformed while passing through the interior of the jewel due to the characteristics of the jewel, such as the refractive index thereof
