Glossary ISO sensitivity The sensitivity of the camera to light, based on the equivalent film speed used in a film camera. At higher ISO sensitivity settings, the camera uses a higher shutter speed, which can reduce blur caused by camera shake and low light. However, images captured with high sensitivity are more susceptible to noise. 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. MPO (Multi Picture Object) An image file format that contains multiple images in a file. An MPO file provides a 3D effect on MPO-compatible displays, such as 3D TVs or 3D monitors. 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 degrade the quality of images. Appendixes 136
