The sensor is the "eye" of a the camera. It is a device similar to a computer chip, which senses light focused on its surface, like electronic film.
CCD is one of two main types of image sensor. The other type is CMOS. 3MOS are three CMOS sensors.CCD sensors have historically provided better image quality, although the newest and best CMOS sensors match CCD quality.CCD sensors require some additional circuitry compared to CMOS sensors, which can have a minor negative impact on size, cost, and battery life in small devices such as camera phones.CMOS - (complementary metal oxide semiconductor)sensors include basic image-processing circuitry that CCD sensors do not. This gives devices with CMOS sensors an edge when it comes to size, cost, and battery life.
How many megapixels should the camera sensor have?
This value is measured against a 35mm slide or negative.
Digital zoom is a function used to make the image seem more close-up. This type of zoom will result in a loss of quality because the image is simply being enlarged.
Optical zoom means that the lense physically extends to magnify your subject. A motor controls the lens movement. When you press the switch to "W" or "T," the subject is either magnified or reduced in size. The "W" stands for "wide-angle" (reduce). The "T" stands for "telephoto" (magnify). Optical zoom always give better quality than digital zoom.
|Filter Size||46 mm|
|Focal Length (Wide-Tele)
Indicates the magnification and angle of view of a lens. The human eye sees things roughly the same as a 45mm focal length of a lens for a 35mm camera. Anything shorter is classed as a wide-angle, while longer focal lengths are telephoto.
|Focal Length (35mm equiv)
The focal length of a lens is defined as the distance in mm from the optical center of the lens, where the rays of light hits the lens to the focal point, which is located on the sensor or film if the subject (at infinity) is "in focus".
An adjustable opening inside the camcorder that limits the amount of light passing through a lens or onto a mirror.
|Image Stabilization Type
Optical, or hardware, image stabilization produces the best results, and consists of either a gyro mechanism that detects small movements of the lens and compensates for them or, for digital camcorders, a liquid- or gel-based prism mounted in front of the lens that bends the light so that the image falls on a fixed point on the CCD.
Electronic, or software, image stabilization is less expensive but is available on digital camcorders only and is considered to be less effective. This method takes the full image, pans and scans to blunt movement, and crops the outer portion of the frame to reduce the sense of motion.
|Flash / Light||Yes|
A video camera plays either in mono or stereo sound. Stereo sound creates a greater audio experience.
|Max Video Resolution||1080p|
|Video Resolutions||1920x1080 (28Mbps), 1920x1080 (24Mbps), 1920x1080 (17Mbps), 1440x1080 (9Mbps), 1440x1080 (5Mbps), 720x567 (9Mbps)|
|Recordable Files||MPEG-2, MPEG-4|
LCD - Liquid Crystal Display (LCD) is a screen made of buoyant crystal. These screens are very flat and small on camcorders. The LCD screen enables you to see the result of your filming directly on the screen. In effect it works like a small TV.
|Display Size||3 in|
Hard drive or Flash memory.
|Memory Stick||MS PRO Duo / MS PRO-HG Duo / MS XC-HG Duo|
