Instant Film Playback System with Separated QR Code
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data playback systems face the issue of two-dimensional codes hindering the view of images when printed, especially when overlapped, leading to partial image obstruction.
Innovation Solution
A data playback system comprising a server and a terminal that downloads and plays image and sound data, where the terminal reads access information from a two-dimensional code printed on the medium, allowing the image data to be displayed without the recording information, and sound data to be played, while the printer uploads image and sound data to the server with generated access information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the two-dimensional code is printed so as to be overlapped with the image, then the access information to sound data can be provided on the printout, but a part of the image is not seen due to the two-dimensional code
Solution Approach 1:
The patent extracts the two-dimensional code from the image area and places it in a separate margin area. The image is printed in a first area while the two-dimensional code is printed in a margin area adjacent to the first area, ensuring they do not overlap. This allows the image to be fully visible while still providing access information to sound data through the separated two-dimensional code.
2Object-affected harmful factors
If the two-dimensional code is printed separately from the image, then the image can be viewed clearly, but the access information to sound data requires additional space
Solution Approach 1:
The patent utilizes the margin area, which is a local region adjacent to the main image area, to place the two-dimensional code. This approach uses otherwise underutilized space effectively, providing separate placement for the code without significantly increasing the overall printout area while maintaining image clarity in the primary viewing region.
Data Source
AI summary
There are provided a data playback system, a data playback method, a data playback terminal, a printer, and a server which are capable of playing sound from a printout and viewing a favorable image.Image data of an image printed on an instant film and sound data associated with the image data are stored in a data storage server. In a case where a two-dimensional code printed with the image on the instant film is read by a data playback terminal, access information to the image data of the printed image and the sound data associated with the image data is obtained. The data playback terminal accesses the data storage server based on the obtained access information, and downloads and plays the image data of the printed image and the sound data.
