Glossary JPEG (Joint Photographic Experts Group) A lossy method of compression for digital images. JPEG images are compressed to reduce their overall file size with minimal deterioration of the image resolution. LCD (Liquid Crystal Display) A visual display commonly used in consumer electronics. This display needs a separate backlight, such as CCFL or LED, to reproduce colors. Macro This feature allows you to capture close-up photos of very small objects. When using the macro feature, the camera can maintain a sharp focus on small objects at a near life-size ratio (1:1). Metering The metering refers to the way in which the camera measures the quantity of light to set the exposure. MJPEG (Motion JPEG) A video format which is compressed as a JPEG image. Noise Misinterpreted pixels in a digital image that may appear as misplaced or random, bright pixels. Noise usually occurs when photos are shot with a high sensitivity or when a sensitivity is automatically set in a dark place. 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. Appendixes 123

Glossary
Noise
Misinterpreted pixels in a digital image that may appear as
misplaced or random, bright pixels. Noise usually occurs when
photos are shot with a high sensitivity or when a sensitivity is
automatically set in a dark place.
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.
JPEG (Joint Photographic Experts Group)
A lossy method of compression for digital images. JPEG images
are compressed to reduce their overall file size with minimal
deterioration of the image resolution.
LCD (Liquid Crystal Display)
A visual display commonly used in consumer electronics. This
display needs a separate backlight, such as CCFL or LED, to
reproduce colors.
Macro
This feature allows you to capture close-up photos of very small
objects. When using the macro feature, the camera can maintain
a sharp focus on small objects at a near life-size ratio (1:1).
Metering
The metering refers to the way in which the camera measures the
quantity of light to set the exposure.
MJPEG (Motion JPEG)
A video format which is compressed as a JPEG image.
