Solution Overview
Problem
Central person determining processing on handheld information terminals is inefficient due to high-load processing requirements, leading to prolonged processing times, especially in low-speed communication environments, and existing solutions do not adequately account for varying data processing speeds between terminals and servers.
Innovation Solution
A central person determining system that includes an information terminal and a server, where the terminal performs face detection and generates face image data, which is then transmitted to the server for processing, allowing for selection of an optimal processing flow based on communication and data processing speeds to minimize determination processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If central person determining processing is performed on a handheld information terminal, then the processing can be done locally without network dependency, but the processing time becomes excessively long due to high computational load
Solution Approach 1:
The patent segments the central person determining processing into two parts: face detection and face image data generation are performed locally on the handheld terminal, while the computationally intensive central person determination processing is performed remotely on a server. This segmentation allows the terminal to maintain local processing capability for initial steps while offloading time-consuming operations to reduce overall processing time.
Solution Approach 2:
The patent introduces a server as an intermediary between the handheld terminal and the final processing result. The terminal sends face image data to the server, which performs the central person determination and returns the result. This intermediary approach enables the terminal to avoid direct computation of the most resource-intensive operations while maintaining local control over data transmission and reception.
2Productivity
If all image data is transmitted to the server for processing, then the processing speed improves due to server power, but the communication time and data transmission load increase
Solution Approach 1:
The patent extracts only the necessary face image data from the complete image set on the terminal and transmits only this extracted portion to the server. By taking out only the relevant face regions rather than transmitting all image data, the system achieves fast server-side processing while minimizing communication time and data transmission load.
Solution Approach 2:
The patent performs preliminary face detection and face image data generation on the terminal before transmission to the server. This preliminary action prepares the data in advance in a format optimized for server processing, reducing the server's computational burden and enabling faster final processing while minimizing the amount of data that needs to be transmitted.
3Measurement precision
If face detection and processing is performed on every image, then comprehensive central person determination is achieved, but the computational load and processing time increase significantly
Solution Approach 1:
The patent applies partial action by performing face detection and processing only on images that contain face images, rather than processing every image in the set. The system identifies and processes only the relevant subset of images containing faces, achieving comprehensive central person determination among face-containing images while improving processing efficiency by avoiding unnecessary processing of non-face images.
