Abstract

Customers require that camera shutter and diaphragm size and power consumption are minimized but shutter speed maximized for the electromagnetic shutter units used in digital still-camera and video cameras. This paper describes the problems with past shutter and diaphragm units and proposes a new shutter unit based on simulation analysis. We compare the prototype model with simulated shutter speed data. Experimental results ascertain the effectiveness of this approach. Simulation results agreed quite well with experimental results.
