Superimposed Light Code Transmission for Seamless File Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing file sharing methods require pre-acquisition of communication information, device pairing, and user interruption for settings, making them cumbersome and inconvenient, especially when trying to separate normal images from encoded codes.
Innovation Solution
An information processing device uses an image sensor to display images with superimposed light components that change over time, allowing encoded information like file addresses to be transmitted and received without prior setup, using the image sensor to capture and decode these changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a code is superimposed on a normal image for transmission, then information can be transmitted visually, but the code and image cannot be separated on the reception side making information checking difficult
Solution Approach 1:
The patent applies dynamics by making the light component's characteristics change over time according to a time function. This temporal variation allows the receiving terminal to differentiate the coded information from the static background image through time-based analysis, resolving the separation difficulty while maintaining information transmission.
Solution Approach 2:
The patent employs periodic action by causing the light component to vary periodically according to a time function. This periodic variation creates a distinguishable signal pattern that the receiving terminal can detect and separate from the background image, enabling code extraction while preserving the visual information transmission.
2Ease of operation
If email or instant messenger is used for file sharing, then file addresses can be exchanged, but communication information must be acquired in advance
Solution Approach 1:
The patent applies preliminary action by pre-embedding the coded information within the visual image itself. This eliminates the need for separate communication channels or advance information acquisition, as all necessary file sharing information is contained within the image that can be immediately captured and processed.
Solution Approach 2:
The patent uses copying by transmitting information through visual capture of the displayed image. The receiving terminal captures the image containing the coded information, creating a copy that includes all necessary file sharing data, thereby eliminating the need for separate communication protocols or advance information exchange.
3Reliability
If infrared communication or Bluetooth is used, then file addresses can be transmitted, but device pairing or close positioning is required
Solution Approach 1:
The patent replaces mechanical communication systems (infrared, Bluetooth) with optical visualization. Instead of requiring physical device pairing or close positioning, the information is transmitted through visual display and captured by an image sensor, substituting mechanical interaction with optical field-based communication that is inherently more reliable and requires no complex pairing protocols.
4Productivity
If traditional communication methods are used, then file sharing can be performed, but user interruption for settings is required
Solution Approach 1:
The patent applies self-service by making the information transmission self-contained within the visual image. The system automatically encodes and transmits file sharing information through the displayed image, which can be captured and processed without requiring user interruption or manual settings adjustment, thereby maintaining productivity while improving ease of operation.

AI summary
One information processing device may comprise circuitry configured to cause an image to be displayed on a display together with a superimposed light component having a characteristic that changes as a function of time and represents a code to be processed by a receiving terminal. Another information processing device may comprise circuitry configured to process image data from an image sensor, which image data represents an image generated on a display together with a superimposed light component having a characteristic that changes as a function of time, to identify a code represented by the superimposed light component.
