GlossaryAppendixes 152MacroThis feature allows you to capture close-up photos of very small objects. Whenusing the macro feature, the camera can maintain a sharp focus on small objects ata near life-size ratio (1:1).MeteringThe metering refers to the way in which the camera measures the quantity of lightto set the exposure.MJPEG (Motion JPEG)A video format which is compressed as a JPEG image.NFC (Near Field Communication)NFC is a set of standards for radio communication at very close proximity. You canuse NFC-enabled devices to activate features or exchange data with other devices.NoiseMisinterpreted 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 orwhen a sensitivity is automatically set in a dark place.Image sensorThe physical part of a digital camera that contains a photosite for each pixel inthe image. Each photosite records the brightness of the light that strikes it duringan exposure. Common sensor types are CCD (Charge-coupled Device) and CMOS(Complementary Metal Oxide Semiconductor).ISO sensitivityThe sensitivity of the camera to light, based on the equivalent film speed used ina film camera. At higher ISO sensitivity settings, the camera uses a higher shutterspeed, 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 toreduce 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 aseparate backlight, such as CCFL or LED, to reproduce colors.
