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 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. 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 134
