Camera Image Resolution Control via Communication Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Photographing apparatuses face challenges in efficiently transmitting images when communication status is low, as existing technologies do not effectively adjust data amounts based on varying communication speeds and types.
Innovation Solution
Incorporating a photographing apparatus with a communication status checking unit, resolution determination unit, and file generation unit that adjusts image file resolution according to communication speed and type, allowing for efficient image transmission by setting higher resolutions for faster communication speeds and lower resolutions for slower speeds, and generating separate image files with pre-set resolutions for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image transmission is performed using fixed high resolution, then image quality is maintained, but communication bandwidth is excessively consumed and transmission fails under low communication status
Solution Approach 1:
The patent implements dynamic resolution adjustment by making the image resolution variable according to communication status. The resolution determination unit dynamically selects appropriate resolution levels based on real-time communication conditions, transforming the static resolution approach into a dynamic adaptive system that optimizes bandwidth usage while maintaining acceptable image quality.
Solution Approach 2:
The patent changes the resolution parameter of image files based on communication status parameters. By monitoring communication speed and adjusting the resolution parameter accordingly, the system adapts image data characteristics to match current communication capabilities, thereby optimizing transmission efficiency under varying network conditions.
2Productivity
If image resolution is reduced to save bandwidth, then communication efficiency is improved, but image quality deteriorates
Solution Approach 1:
The system dynamically adjusts resolution based on communication status, allowing the image quality to be optimized for each transmission condition. This dynamic approach ensures that image quality is not permanently degraded but rather adaptively adjusted to match current communication capabilities, maintaining the best possible quality under each scenario.
Solution Approach 2:
The patent performs preliminary resolution determination before actual image transmission. The resolution determination unit pre-assesses the appropriate resolution level based on communication status checking, allowing the system to prepare images at optimal resolution levels in advance, thereby avoiding both excessive bandwidth consumption and unnecessary quality loss.
3Adaptability or versatility
If multiple resolution versions are generated and stored, then transmission flexibility is improved, but device complexity and storage requirements increase
Solution Approach 1:
The patent generates multiple resolution versions of images in advance and stores them in the storage unit. This preliminary preparation of various resolution versions allows the system to quickly select and transmit the most appropriate version based on current communication status without requiring complex real-time processing during transmission, thereby balancing flexibility with processing efficiency.
