GLOSSARY
AF (Auto Focus)
A system that automatically focuses the camcorder lens on the subject. Your camcorder uses the contrast to focus automatically.
Aperture
The aperture controls the amount of light that reaches the camcorder’s sensor.
Camcorder shake (Blur)
If the camcorder is moved while the shutter is open, the entire image may appear blurred. This occurs more often when the shutter speed is slow. Prevent camcorder shake by raising the sensitivity, using a faster shutter speed. Alternately, use a tripod, the DIS or OIS function to stabilize the camcorder.
Composition
Composition in photography means arranging objects in a photo. Usually, abiding by the rule of thirds leads to a good composition.
Complementary Metal-Oxide-Semiconductor (CMOS)
CMOS is an image sensor producing images approaching the quality of CCD (charge coupled device) sensors. It consumes less power, meaning a longer battery life on your camcorder.
Digital zoom
A feature that artificially increases the amount of zoom available with zoom lens (Optical zoom). When using the Digital zoom, the image quality will deteriorate as the magnification increases.
Effective Pixel Count
Unlike the total pixel count, this is the actual number of pixels used to capture an image.
EV (Exposure Value)
All the combinations of the camcorder’s shutter speed and lens aperture that result in the same exposure.
Exposure
The amount of light allowed to reach the camcorder’s sensor. Exposure is controlled by a combination of the shutter speed, the aperture value, and ISO sensitivity.
Focal length
106The distance from the middle of the lens to its focal point (in millimeters). Longer focal lengths result in narrower angles of view and the subject is magnified. Shorter focal lengths result in wider angles of view.
F. No (F-Number)
The
*F.No=focal length/diameter of lens aperture
MPEG-4 AVC/H.264
Optical zoom
This is a general zoom which can enlarge images with a lens and does not deteriorate quality of images.
Quality
An expression of the rate of compression used in a digital image. Higher quality images have a lower rate of compression, which usually results in a larger file size.
Resolution
The number of pixels present in a digital image. High resolution images contain more pixels and typically show more detail than low resolution images.
Shutter speed
Shutter speed refers to the amount of time it takes to open and close the shutter, and it is an important factor in the brightness of a photo, as it controls the amount of light which pass through the aperture before it reaches the image sensor. A fast shutter speed allows less time to let light in and the photo becomes darker and more easily freezes subjects in motion.
Tele Macro
This feature allows you to capture
White balance (color balance)
An adjustment of the intensities of colors (typically the primary colors red, green, and blue), in an image. The goal of adjusting the white balance, or color balance, is to correctly render the colors in an image.
