Glossary

A system that automatically focuses the camcorder lens on the subject. Your camcorder uses the contrast to focus automatically.

The aperture controls the amount of light that reaches the camcorder’s sensor.

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 in photography means arranging objects in a photo. Usually, abiding by the rule of thirds leads to a good composition.

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.

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.

Unlike the total pixel count, this is the actual number of pixels used to capture an image.

All the combinations of the camcorder’s shutter speed and lens aperture that result in the same 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.

The 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.

The f-number defines the brightness of lens. Smaller number lens has generally brighter image. The f-number is directly proportional to the focal length and inversely proportional to the lens diameter.

*F.No=focal length/diameter of lens aperture

MPEG-4 AVC/H.264 defines the latest video coding format standardized by the ISO-IEC and the ITU-T, in 2003. Compared with the conventional MPEG-2 format, MPEG-4 AVC/ H.264 has more than twice the efficiency. Your camcorder employs MPEG-4 AVC/H.264 to encode high definition videos.

This is a general zoom which can enlarge images with a lens and does not deteriorate quality of images.

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.

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 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.

This feature allows you to capture close-up images of very small objects. When using the Tele Macro feature, the camcorder can maintain a sharp focus on small objects at a near life-size ratio (1:1).

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.
