GLOSSARY

AF (Auto Focus)

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

Aperture

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

Composition

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

F. No (F-Number)

The F-number defines the ratio of the focal length to the size of the lens aperture (focal length/diameter of lens aperture). The smaller the F-number, the larger the lens aperture and the greater the amount of light that reaches the product’s sensor. Generally, smaller F-numbers provide brighter images.

MPEG-4 AVC/H.264

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 product employs MPEG-4 AVC/H.264 to encode high definition videos.

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 product.

Digital zoom

A feature that artificially increases the amount of zoom available with the zoom lens (Optical zoom). When using the Digital zoom, the image quality will deteriorate as the magnification increases.

Product shake (Blur)

If the product is moved while the shutter is open, the entire image may appear blurred. This occurs more often when the shutter speed is slow. Prevent product shake by raising the sensitivity, using a faster shutter speed. Alternately, use a tripod, the DIS or OIS function to stabilize the product.

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.

Effective Pixel Count

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

Exposure

The amount of light allowed to reach the product’s sensor. Exposure is controlled by a combination of the shutter speed, the aperture value, and ISO sensitivity.

Focal length

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.

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. This 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 provides less time for light to enter. The photo becomes darker, but more easily freezes subjects in motion.

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.
