Examples of types of video input devices include:

A video camera is a camera used for capturing motion picture , initially developed by the television industry but now common in other applications as well. The earliest video cameras were used by the BBC in experimental broadcasts through the 1930s.
 Example:

´  Professional video cameras 

´  Camcorders 

´  Closed-circuit television (CCTV) 

´  Webcams 

´  Mobile Phone Camera

Two Popular Types of Video Editing: 

´  Linear Editing 

 Linear editing is a process of copying one tape to a master tape in sequential.
 

Non-Linear Editing
 

´  Non-linear editing offers the flexibility of video editing, with random access. 

´  It allows to access any frame in a video clip regardless of sequence of the clips. 

´  It allows the editor to change the sequence of the clips at any time, 

´  It is easy to include fades, transitions, and other effects that cannot be achieved in linear editing 

The costs of editing systems have dropped. Some editing software can now be accessed free as web applications 

We often use Computer Monitors and Televisions in our regular life. So CRT technology is employed in these output devices. These CRT Displays are used mostly by Graphic professionals. Because CRT Technology offers good vibrant and very good accurate colour.

Monitor is also referred as Visual Display Unit. Monitor is an electronic output device where we can see entire output through this device.

Random Scan Display is formed by using various geometrical primitives. So they are formed using Curves, Points, Lines, and Polygons

In the name Raster Scan Display, the Raster word means a rectangular array of points. or else array of dots. So Group of dots are known as Pixels, and image is sub grouped in to a sequence of stips.These are called Scan lines, and these scan lines are further divided in to Pixels.

This kind of Flat Panel Display surrounds number of various electronics visual display techniques or methods. So that it obviously become lighter and very thinner about 100mm.These kind of Flat Panel Displays are used in many portable devices.

Various type of Video Display: 

1. Television Screen

2. Projector 

3. Video Wall 

Video Display 

TV Set 

´  Is a device that combines a tuner, display, and speakers for the purpose of viewing television. 

´  Display unit is being changed from CRT to LCD/LED 

´  Latest TV Set has several  input connection; VGA,HDMI,RCA,SVGA, 

•  CRT 

–      Bulky, heavy, use vacuum tube technology. 

– Using technology that was developed in the 19^th century.  

•  LCD 

– First LCD laptop monitors were very small due to manufacturing costs but now are available in a variety of sizes.  

– Light, sleek, energy-efficient, have sharp picture.  
 

Projection Technology 

´  CRT projector using cathode ray tubes. This typically involves a blue, a green, and a red tube. This is the oldest system still in regular use, 

´  LCD projector using LCD light gates. This is the simplest system, making it one of the most common and affordable for home theaters and business use. 

´  DLP projector using Texas Instruments’ DLP technology. This uses one, two, or three microfabricated light valves called digital micromirror devices (DMDs). 

3.1.4 - Identify the video display devices

There are multiple video displays technologies, some of them are:
- CRT (cathod ray tube)
- LCD (liquid crystal display)
- LED (light emitting diode)
- OLED (organic light emitting diode)
- QLED (quantum light emitting diode)

Here are some of the specifications :

However, expensive, high-end, high-definition dedicated cameras are still commonly used by professionals.

Digital and movie cameras share an optical system, typically using a lens with a variable diaphragm to focus light onto an image pickup device.^[3] The diaphragm and shutter admit the correct amount of light to the imager, just as with film but the image pickup device is electronic rather than chemical. However, unlike film cameras, digital cameras can display images on a screen immediately after being recorded, and store and delete images from memory. Many digital cameras can also record moving videos with sound. Some digital cameras can crop and stitch pictures and perform other elementary image editing. 

The key light, as the name suggests, shines directly upon the subject and serves as its principal illuminator; more than anything else, the strength, color and angle of the key determines the shot's overall lighting design.

In indoor shots, the key is commonly a specialized lamp, or a camera's flash. In outdoor daytime shots, the Sun often serves as the key light. In this case, of course, the photographer cannot set the light in the exact position he or she wants, so instead arranges it to best capture the sunlight, perhaps after waiting for the sun to position itself just right.

´  Soft light does not cast shadows 

´ 

Soft light use is popular in cinematography and film. 

´  Cast shadow-less light. 

´  Fill lighting. Soft light can reduce shadows without creating additional shadows. 

´  Make a subject appear more beautiful or youthful through making wrinkles less visible. 

The lens on a video camera serves as the same function as a still camera's lens. It draws in light and captures the image at which the camera points. This telescopic piece can have multiple lenses within it. A number of dials on the tube will shift the lens positions by turning them, and this controls how the lenses focus the light they receive to clarify the picture.

Viewfinder

The viewfinder is directly connected to the lens and is meant to provide access to the image for the user. This can be a simple eye-sized window, or it may be a small pixel screen that folds into the camera when not in use; many models have both versions. Viewfinders also double as a video screens for playing back the recorded image.

Microphone

The lens picks up only the visual images for the camera, meaning this alone would create a silent picture. Video cameras, therefore, also include microphones that record sound in the area. The microphone is usually mounted next to the lens and pointing in the same direction so the audio and video are closely in sync.

Recorder

The recorder processes the images received by the lens and the sound from the microphone and records them to memory. On older analog cameras, this would record the image onto a magnetic tape within a cassette. Some cameras would take full VCR tapes, but others require miniature versions of these cassettes or other formats like Hi8. Digital cameras eliminate the need for cassettes. The camera instead records the image as a computer video file. In most cases, this file is in JPEG format.

Controls

The camera's main controls include the Power switch and the Record button. It will also include playback buttons such as Play, Stop, Rewind, Fast Forward and Pause. The controls also include output ports to connect the camera for playback. All cameras should include the basic red/white/yellow RCA cables to connect to any playback machine, but they can also include USB or FireWire controls for connection to a computer.

Battery

Battery power is essential for camera use. Every camera is equipped with a rechargeable battery. Most batteries are lithium-ion based, and each is made and designed to work specifically with its camera model only. A full battery charge can usually take 12 hours, meaning an overnight charge will suffice.
