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.
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 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.
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.
F. No (F-Number)
The
ÚF.No=focal length/diameter of lens aperture
MPEG-4 AVC/H.264
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 stabilise 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.
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.
