Working Principle OF Video Camera

A video camera contains several key internal parts that allow it to capture images, including a lens to focus light, an aperture to control the light amount, a shutter to control exposure time, a beam splitter to separate light into colors, an imaging device like a CCD or CMOS sensor to convert light to electrical signals, a viewfinder to preview the image, and a storage device to save the recorded images. Video cameras can be analog or digital and are used for different applications such as studio, field, or mobile photography. The internal components work together to record moving images onto a storage medium.

INTRODUCTION

 Camera is an electronic device which helps to


capture moving and still images on any storage
device.

INTERNAL PARTS OF CAMERA

 Lens
 Aperture
 Shutter
 Beam Splitter
 Imaging Device (CCD, CMOS & Xmor)
 View Finder
 Storage Device
Vidicon Camera
Raster scanning
GRAPHICAL PRESENTATION
Digital Camera
LENS

 It is a glass medium which gives


proper direction to light rays.
 It determines what camera can
see.
 It selects a certain field of view
and produces a small optical
image of object.
APERTURE

 Controls the amount of


light
 Decide the depth of field
 Measure through F-stop
Number
SHUTTER SPEED

 The Length of time a shutter remains open to allow light to


reach the imaging device is called shutter speed
 It is a thin sheet covering the imaging device.
 Shutter Speed is measured in second or fraction of second
 Using fast shutter speed is to capture fast moving subject
and slow shutter speed for slow moving subject.
 Fast shutter speed requires large aperture and slow
shutter speed requires small aperture
BEAM SPLITTER

 It contains various prism


and filter.
 Prisms break up incident
light into seven colours.
 Filters separate the white
light into three primary
colours namely Red, Green
and Blue.
IMAGING DEVICE

 It is a transducer which
converts light energy into
electronic signals.
 It contain millions of
image sensing elements
called pixels.
 CCD and CMOS are
widely used as imaging
device.
CCD – Charge Coupled Device
Color Sensor
VIEW FINDER

 There are two types of View


Finder.
 Monochrome
 Colour display (LCD)
 It presents the image what
our camera lens see.
 Size varies according to their
usage.
STORAGE DEVICES
 Various Types of Storage Device

 8mm DVC-PRO cassette

 ½’’ Beta –SP tape format

 Memory stick

 CD Rom
