Image Distribution Apparatus Preventing Duplication via Streaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image distribution systems fail to prevent the duplication of sensitive still images, as they often require dedicated software installations and do not effectively manage real-time streaming of images to prevent storage on receiving devices.
Innovation Solution
An image distribution apparatus and method that generates a moving image from still images and performs real-time streaming distribution, preventing duplication by transmitting a lower-resolution moving image instead of the original still images, which are not stored on the receiving device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If still images are transmitted directly to a PC, then the image quality is preserved, but the images can be stored and duplicated on the receiving device
Solution Approach 1:
The patent changes the format and resolution parameters of the image data by converting still images into lower-resolution moving images with added noise. This transformation maintains visual usability while preventing accurate duplication and storage of the original high-quality images on receiving devices.
Solution Approach 2:
The patent creates temporary, low-quality moving image versions that serve their purpose for viewing but are unsuitable for storage or duplication. These disposable image representations are transmitted in real-time and cannot be easily converted back to the original high-quality still images.
2Duration of action of stationary object
If dedicated software is installed on the receiver-side device to manage time-limit, then time-limit management is achieved, but the system becomes large-scale and complex
Solution Approach 1:
The patent extracts the time-limit management functionality from the receiving device and relocates it to the transmitting device. The transmitting device embeds time-limit information in the moving image data and controls the distribution duration, eliminating the need for dedicated management software on the receiver-side device.
Solution Approach 2:
The patent introduces moving image data as an intermediary carrier that embeds time-limit information. This intermediary format allows the transmitting device to control distribution duration without requiring complex software installations on receiving devices, simplifying the overall system architecture.

AI summary
In order to prevent a duplicate of a still image from being generated, an MFP includes an image obtaining portion to obtain one or more still images, a moving image generating portion to generate a moving image in which the obtained still images are displayed sequentially, and a distribution portion to perform real-time streaming distribution of the moving image in response to a request from a PC connected to a network.
