ABSTRACT

As multimedia PC networks are becoming more widespread, video cameras are seeing increased use as image input devices. These cameras are essential devices for applications involving visual communications, such as video conferencing and video mail.

Hitachi has successfully developed a cost-effective video camera for multimedia systems by applying technologies which were originally developed for home-use video cameras and camcorders.

Adopting a highly integrated digital signal processing LSI, called the DSP-III, the camera simultaneously achieves both high performance and compact size. The LSI provides various useful functions, such as automatic picture quality control, electronic zooming, and external control from a host machine, the latter of which renders the application useful for applications involving visual communications.

The camera also features a flexible design that is adaptable to various kinds of multimedia systems.
