Paper Abstract

A high precision exposure control system using a frame interline transfer (FIT) CCD image sensor and a compact aperture mechanism is proposed for consumer still video cameras. In this system, an electronic shutter, which is a feature of the FIT CCD image sensor, is used instead of a mechanical shutter. This electronic shutter can be used with flash. The aperture mechanism is constructed of three different size apertures and two solenoids for aperture selection. The experimental results show that the exposure error of the entire system is 0.15 EV or less.
