Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems face challenges in achieving high accuracy and reducing latency when handling and analyzing photographed images, leading to discomfort and potential data loss due to increased load on data transmission and analysis, which can result in inaccurate image display and transmission band oppression.
Innovation Solution
The system incorporates a communication portion, retransmission request producing portion, image analyzing portion, output data producing portion, and processing condition adjusting portion to establish communication with an image pickup device, issue retransmission requests for missing data, analyze the image, produce output data, and adjust allowable time settings based on analysis results, ensuring efficient data handling and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the resolution or frame rate of the photographed image is increased, then the picture expression quality is improved, but the data size increases, resulting in increased transmission load and analysis time
Solution Approach 1:
The patent segments image data into multiple packets for transmission. When packet loss occurs, only the missing packets are retransmitted rather than the entire image data, significantly reducing retransmission time and data volume while maintaining high image quality
Solution Approach 2:
The system performs preliminary error detection by checking packet arrival status before complete image reconstruction. This allows early identification of missing data and triggers targeted retransmission requests, reducing overall processing time
2Measurement precision
If the data size is increased to improve image quality, then the analysis accuracy is improved, but the transmission band is oppressed and data loss becomes more likely
Solution Approach 1:
Large image data is divided into smaller packets, reducing the impact of transmission errors on the entire dataset. Only affected packets need retransmission, maintaining high reliability while enabling high-resolution image transmission
Solution Approach 2:
The system implements feedback mechanisms where the receiver monitors packet arrival and sends retransmission requests for missing packets. This ensures reliable data transmission without requiring excessive redundancy in the original transmission
3Speed
If the allowable time for data transmission is reduced to improve currency, then the response speed is improved, but the risk of data loss increases
Solution Approach 1:
The system sets appropriate retransmission timeout values in advance based on network conditions. This allows the system to maintain fast response for complete packets while having pre-configured mechanisms for handling missing data within acceptable timeframes
Solution Approach 2:
The system can proceed with image reconstruction using received packets even if some are missing, rather than waiting for complete data. This skipping approach maintains currency by displaying available information while triggering selective retransmission for missing portions

AI summary
In an information processing apparatus 200a, a communication portion 250 acquires a data stream of a photographed image in a wireless communication manner. A packet analyzing portion 252 detects a lost packet and a retransmission request producing portion 254a issues a retransmission request for the packet within a predetermined allowable time. An image analyzing portion 262a analyzes the data associated with the photographed image. An information processing portion 264 and an output data producing portion 266 execute information processing by utilizing an analysis result, and produce output data, respectively. A processing condition adjusting portion 268 adjusts the allowable time of the retransmission request by the retransmission request producing portion 254a based on the analysis result in the image analyzing portion 262a.
