Solution Overview
Problem
Conventional methods for home electric appliances with insufficient or no communication functions due to cost constraints, and limitations in using three-color light sources for optical spatial transmission, restrict effective information display and communication.
Innovation Solution
A display method utilizing a system that captures and decodes light identification information from a transmitter to superimpose augmented reality images on a captured image, reducing processing load by pre-selecting relevant images from a server, and allowing flexible target region recognition using bright line patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional three-color light sources are used for optical spatial transmission, then communication can be established between devices, but the ability to display valuable images to users is limited
Solution Approach 1:
The patent divides the light transmission function into two independent components: communication function (using luminance changes to transmit data) and display function (using bright line patterns to encode image information). This segmentation allows the receiver to separately process communication data and image information, enabling both communication and valuable image display simultaneously without interfering with each other.
Solution Approach 2:
The patent makes the visible light transmission system universal by enabling it to perform multiple functions: data communication through luminance modulation and image information transmission through bright line patterns. The receiver can decode both types of information from the same light source, making the system adaptable to various applications including communication, display, and augmented reality.
2Loss of information
If comprehensive image processing is performed to display valuable images, then user-valuable display is achieved, but processing load increases
Solution Approach 1:
The patent applies preliminary action by pre-selecting and pre-processing only the image data relevant to the specific target object before transmission. The bright line pattern encodes only the necessary image information for the target region, so the receiver needs to process only this pre-filtered data rather than performing comprehensive full-image processing, significantly reducing the processing load while maintaining image quality.
Solution Approach 2:
The patent extracts only the essential image information related to the target object from the complete image data. By encoding only the relevant portion through bright line patterns and transmitting it alongside communication data, the system avoids transmitting and processing unnecessary image information, thereby reducing processing complexity while preserving the valuable display content.
3Measurement precision
If rigid target region recognition is used, then accurate positioning is achieved, but flexibility in recognition is reduced
Solution Approach 1:
The patent applies dynamics by making the target region recognition adaptive rather than rigid. The system can dynamically adjust the recognition approach based on the bright line pattern characteristics and target object properties. This allows the receiver to flexibly interpret the encoded image information while maintaining accurate positioning, accommodating various target types and conditions without requiring fixed recognition methods.

AI summary
A display method capable of displaying an image valuable to a user is provided. The display method for a display device to display an image includes: obtaining a captured display image and an image for decoding by an image sensor capturing a subject (SL11); decoding the image for decoding to obtain light identification information (light ID) (SL12); transmitting the light ID to a server (SL13); obtaining an augmented reality (AR) image and recognition information corresponding to the light ID from the server (SL14); out of the captured display image, recognizing a region corresponding to the recognition information as a target region (SL15); and displaying the captured display image with the AR image superimposed on the target region (SL16).
