Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting devices that modulate light according to an image struggle to generate light suitable for illumination while maintaining the features of the original image, particularly in indoor settings where outdoor scenes need to be replicated.
Innovation Solution
A lighting system comprising a receiving circuit, memory for depth information, an image processor that converts images into gradated single-color representations, a light source, a light modulator, and a light emitter, which together generate illuminating light that mimics the features of an outdoor subject for indoor use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If light is modulated according to an original image to maintain image features, then the feature of the original image is preserved, but the light is not suitable for illumination
Solution Approach 1:
The patent segments the original image into depth layers using depth information, separating the image into multiple depth-based layers. This allows different parts of the image (different depths) to be processed differently, enabling both image feature preservation and illumination suitability by controlling light transmission through layered structures
Solution Approach 2:
The patent applies local quality by creating a light shielding layer with spatially varying light shielding properties corresponding to different depth regions. Each depth layer receives customized light modulation, where the light shielding degree varies locally across the image to maintain both image characteristics and provide suitable illumination
2Manufacturing precision
If conventional light modulation is used to maintain original image features, then image fidelity is improved, but the lighting quality for indoor illumination deteriorates
Solution Approach 1:
The patent introduces a light shielding layer as an intermediary between the light source and the modulated light output. This intermediary layer, controlled by the image processing unit, mediates between the original image features and the illumination requirements, adjusting light transmission to achieve both high image fidelity and good lighting quality

AI summary
A lighting device includes: a receiving circuit which obtains a first image including a subject; a memory which obtains depth information indicating a depth of the subject in the first image; an image processor which converts the first image obtained, into a second image in which the subject in the first image is represented by gradation of a single color, the gradation being different according to the depth indicated by the depth information; a light source; a light modulator which modulates light emitted from the light source, according to the second image; and a light emitter which emits the modulated light.
