Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image transmission methods increase processing load by compressing image data based on the ability of the transmission destination apparatus, leading to inefficient data transmission.
Innovation Solution
A transmission device and method that processes and transmits files with a data structure including original images and attribute information, where the file processing unit generates a file with common attributes added to unique attributes of the image for transmission, specifically cutting and formatting the image to match the display ability of the receiving device, using Exif tags defined by the Exif standard.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image data is compressed in accordance with the ability information of the transmission destination apparatus, then compatibility with various display devices is improved, but the processing load at the time of data transmission is increased
Solution Approach 1:
The patent applies preliminary action by pre-processing the original image into multiple images for transmission with different resolutions before transmission. The file processing unit creates a structured file containing the original image and multiple pre-generated display images at various resolutions, along with attribute information linking them. This eliminates the need for real-time compression processing at transmission time, reducing the processing load while maintaining compatibility with various display devices through selective transmission of appropriately sized images.
2Reliability
If image data is compressed based on transmission destination ability, then standard violation of images for transmission is prevented, but data transmission time is increased
Solution Approach 1:
The patent performs preliminary generation of multiple images for transmission at different resolutions with proper Exif attribute information before transmission. By pre-creating these images with correct formatting and attributes, the system ensures standard compliance without requiring time-consuming processing during the actual transmission operation, thus reducing data transmission time while maintaining reliability.
Solution Approach 2:
The patent implements dynamics by making the transmitted image data adaptive to different display abilities. The file contains multiple images for transmission with different resolutions and attributes, allowing the receiving device to dynamically select the most appropriate image based on its display capabilities. This dynamic selection approach ensures standard compliance across different devices without requiring real-time compression processing.
3Manufacturing precision
If original resolution images are transmitted, then image quality is maintained, but data transmission load is increased
Solution Approach 1:
The patent applies segmentation by dividing the original high-resolution image into multiple images for transmission with different resolutions. The file processing unit creates a structured file containing the original image and multiple segmented versions at progressively lower resolutions, each with appropriate Exif attributes. This segmentation allows the system to transmit only the necessary resolution level based on the receiving device's capabilities, maintaining image quality where needed while reducing overall data transmission load.
Solution Approach 2:
The patent implements parameter changes by varying the resolution parameter of images for transmission based on display ability. The file contains multiple images with different resolution parameters and associated Exif attributes indicating their suitability for different display scenarios. This allows the receiving device to select images with appropriate resolution parameters, maintaining high image quality when needed while reducing data transmission load when lower resolutions suffice.
