Development of Consumer Camera-Based Pseudo High-Speed High-Resolution Capturing System Using Phase-Shift Photographing

摘要

In this paper, we develop a high-speed, high-resolution camera system for capturing a periodical phenomenon. This method enables high-speed, high-resolution capture even utilizing a low-cost low-specification consumer camera. To realize this performance, we utilize the phase- shift photographing technique. In this paper, firstly, we describe our system which consists of a consumer camera, a lighting system, and a synchronous circuit. Then, we conduct experiments to capture a time-series image of a fuel injection process as an example case. After that, we synthesize an image from the multiple captured images. Finally, the availability of the method is confirmed in comparison to the images captured by a higher specification camera.
