Title: Toshio Iwasaki: Inventor of an Infrared Image Monitoring System.
Introduction
Toshio Iwasaki is an inventor associated with Kanagawa, Japan, and Fujitsu Corporation. His work includes a patent for monitoring scenes by analyzing infrared camera images.
Latest Patents
Iwasaki is associated with 1 patent, titled “Monitoring System Using Infrared Image Processing.” The system compares temperature data for each pixel in an infrared camera frame with the corresponding data from a previous frame. It then analyzes changed pixels using a histogram that relates the amount of temperature change to the number of affected pixels. When the detected change and affected area exceed a threshold, the system identifies a potentially significant object and can trigger an alarm. It can also preserve circulating frame memories, allowing visible-light scenes and temperature patterns from before, during, and after the trigger to be displayed.
Career Highlights
Iwasaki’s patent describes an approach to detecting objects through changes in infrared imagery. By combining frame-to-frame comparison with threshold-based analysis, the system can support alarm activation and the review of recorded scenes.
Collaborations
Ryuichi Ueda and Kanji Hirota are identified as Iwasaki’s coworkers. The available information does not specify their roles in the patent or their particular contributions.
Conclusion
Toshio Iwasaki’s patented monitoring system uses infrared image processing to detect significant temperature changes, trigger alarms, and preserve visual records for review.
