Video cameras come in many forms and sizes and can be
used for a variety of purposes. Some video cameras permit the user to
record the captured video signal on video tape inserted within the
camera housing. The video camera for recording/storage is called
camcorder which usually includes camera, recording/playback part and
monitor in a unit case. Other video cameras however, merely transmit the
captured video signal to a remote location for viewing on a monitor or
recording on a video tape recorder (VTR). In recent years, a video
camera for converting an object image imaged by a photographing optical
system into an electrical signal using a photoelectric conversion
element such as a solid-stage image pickup element, e.g., a CCD or a
CMOS image sensor, and recording the electrical signal onto a recording
medium such as a magnetic tape has become popular. The CCD image sensors
used in video cameras are area sensors comprising a matrix of sensor
elements or pixels. The image signal is acquired in the form of
electrical charge by the sensor elements, read into a plurality of
vertical transfer registers, then shifted into a horizontal transfer The
personal computer market has grown rapidly in the past decade. Recent
trends have focused on the configuration of the computer to perform a
variety of user defined functions, including connecting to the internet
and communicating with others also so connected. Video cameras have
increasingly been used to augment the communication between individuals
using the internet. Video cameras have become miniaturized yet so
versatile that ordinary people can easily take such a camera anywhere
and shoot very high quality movies. |
