Display Device Luminance Transmittance Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies lack the ability to provide rich expressive effects by combining images, as they only apply uniform transmittance to the mask image, limiting the visual impact and gradation of the combined image.
Innovation Solution
A display device and control method that generate a third image by combining a first image with a second image, where the luminance information of the second image is converted into transmittance, allowing for varied gradation, position, shape, and color adjustments to enhance the expressive effect of the first image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If uniform transmittance is applied to the mask image, then the processing is simple, but the expressive effect is limited
Solution Approach 1:
The patent applies different transmittance values to different regions of the mask image based on luminance information. Each pixel or region of the mask image is assigned a transmittance value corresponding to its luminance level, creating local variations in transparency that enhance the expressive effect of the combined image while maintaining a relatively simple processing approach.
2Adaptability or versatility
If luminance information is converted to transmittance for the second image, then the expressive effect is enhanced, but the processing complexity increases
Solution Approach 1:
The patent converts luminance information (a visual parameter) into transmittance values (an optical parameter) for the second image. This parameter transformation allows the luminance characteristics of the second image to control the transparency of the mask image, creating rich expressive effects through gradient variations and positional changes without requiring complex processing algorithms.

AI summary
A projector includes a video processing section configured to generate a third image by combining, on the basis of transmittance, a first image based on first image information and a second image generated by converting luminance information of second image information including the luminance information into the transmittance and an image forming section configured to display the third image.
