Paper Abstract

A PC digital still camera based on a mega-pixel CCD area array is presented. This camera can be used as an image input device in the applications of multimedia. The system is equipped with a conventional camera lens, and an 1.5 mega-pixel progressive color CCD area array. A driving circuit is designed to control the focusing and the iris of the lens in order to perform auto/manual focus and auto/manual exposure functions. The CCD image sensor is also used as a sensor for auto focus, auto exposure and auto white balance control. This could eliminate the additional sensors. A shutter wheel is built for continuous exposure, which allows the host computer to display the entire field of view for preview without using an additional optical viewfinder. The digital signal processing is implemented in a computer software for interpolation, color reproduction, and edge enhancement, etc. A SCSI interface is used to connect to a host computer for data and command transmission.
