Media
?
 |
 |
|
| Meaning: Video captured by Camcorder is saved on the Media. Different types of media available are Hi8, MiniDV, DVD and in-built Hard Disk Drives.How it functions: The Video captured by the lens of the Camcorder is saved on the media and then can be used for Playback. Hi8 and MiniDV tapes are Analog Types of Media whereas DVD and Hard Disk Drives are Digital Types of Media. DVD's used for recording are available in two types, Single Sided and Double Sided. Benefits: The Hi8 and MiniDV tapes can record maximum upto 90 minutes but a DVD disc and the HDD can record upto 28 hrs of Video Recording. |

Sensor Resolution (Megapixel)
?
|
|
|
| Meaning: Sensor resolution is the Number of pixels used to capture an image or a video. A good image or video resolution is achieved by combination of image or video sensor resolution and lens resolution.Benefits: The Higher the image or video sensor resolution, the better the image or video quality. |

Optical Sensor Size
?
|
|
|
| Meaning: Optical Sensor Size is often reffered to with a type designation using imperial fractions such as 1/1.8 or 2/3.
How it functions: Optical Sensor size is larger than the actual sensor diameters. The size designation does not define the diagonal of the sensor area but rather the outer diameter of the long glass envelope of the tube.
Benefits: The Pixels are much smaller, which is a key reason for the quality difference, especially in terms of noise and dynamic range. |

Optical Sensor Type
?
|
|
|
| Meaning: The two types of censors are CCD and CMOS. CCD - Charged Coupled Device sensor is a light sensitive chip used for Image gathering. CMOS - Coplimentary metal oxide Semiconductor is another type of image sensor found in digital cameras also.
How it functions: CCD is the most common form of photosensitive cells used to convert incoming light into electrical signals in Digital cameras. In their normal condition these are greyscale devices. To create colour, a colour pattern is laid down on the sensor pixels, using RGBG color mask. (Red, Green, Blue and Green).
Benefits: A digital image sensor converts light into electrical signals, which are then converted into an video inside the camcorder using the Camcorder video processor. |

Aperture (f/stops)
?
|
|
|
| Meaning: Aperture is the opening in a lens through which light passes to the sensor to create an image.
How it functions: Aperture size is usually caliberated in f-stops (f-numbers). The Higher the f number the smaller is the aperture. The common f-stops are f/2, f/2.8, f/4, f/8 etc. The aperture also defines the depth of field. Smaller the f-number, larger will be the depth feild and vice-versa. Thus, you can focus on certain objects for getting special effects.
Benefits: The quality of the video depends upon the aperture range and shutter speed of the camcorder. |

|
Digital Zoom
?
|
|
|
| Meaning: A Digital zoom is software inside the camcorder that enlarges subject in the video to be shot.How it functions: Due to the doubling of pixels the video begins fuzzier and fuzzier as you enlarge. Digital zoom enlarges the subject of the video to be shot, while reducing the resolution of the video. |

|
Type of Focus
?
|
|
|
| Meaning: Focus is a point at which rays of light meet after being refracted or reflected.
How it functions: In auto focus mode the camcorder automatically focuses on the subject video to be shot in the focus area in the center of the LCD/ View finder. Manual focus disables the camcorders built-in automatic focus system so you can focus the lens by hand. |

Minimum Shutter Speed
?
|
|
|
| Meaning: Shutter speed is the time for which the camcorder exposes the sensor to the light being let in by the aperture setting.
Benefits: The slower the shutter speed, the longer is the exposure time and the image is clear. |
|

|
|

|
Maximum Shutter Speed
?
|
|
|
| Meaning: Shutter speed is the time for which the camera exposes the sensor to the light being let by the aperture setting.
Benefits: The faster the shutter speed, the shorter the exposure time. |

|
Types of Exposure
?
|
|
|
| Meaning: Exposure occurs when light is permitted to strike the sensor.
How it functions: Exposure is determined by how wide you open the lens diaphragm (aperture) and by how long you keep the sensor exposed.
Benefits: There are three types of exposures Automatic, Manaul and Fixed. |
|

|
|
Auto/Manual:±2.0EV in steps of 0.3EV

|
| White Balance
|
Presets
?
|
|
|
| Meaning: It is a function on camcorder to compensate for different colors of light being emitted by different light sources. Some white balance presets are Daylight, Cloudy, Flouresent, Incandescent/ Tungsten, Flash.
Benefits: We don't notice the difference in the temperature because our eyes adjust automatically for it. So unless the temperature of the light is very extreme a white sheet of paper will generally look white to us. However a digital camera does not have the smarts to make these adjustments automatically and sometimes will need us to tell it how to treat different light. |

Image Stabilizer
?
|
|
|
| Meaning: Camcorders with high optical zoom come with an image stabilizing feature.
How it works: It automatically eliminates any camcorder shake like the slight shaky motion that can result as you hold the camcorder thus helping you ensure a crisp, sharp video.
Benefits: To get crisp, sharp, unshaky and blurry video. |

Recording Speed
?
|
|
|
| Meaning: There are three different types of recording speeds XP or HQ (High Quality), SP (Standard Play), and LP(Long Play).
How it functions: HQ or XP mode allows to record shorter duration of video whereas LP allows to record longer duration of video.
Benefits: HQ recorded video always give clear and crisper quality of Video. |

Resolution (Pixels)
?
|
|
|
| Meaning: Resolution measures the sharpness of the display or screen.
Benefits: The number of pixels that can be displayed on the screen is referred to as the resolution of the video. The higher the resolution, the better and clear is the image. |
