Chapter 12 Glossary of terms (Cont.) JPEG (Joint Photographic Experts Group) A compression format for color still images. Photographs (images) shot using this camera are recorded onto the SmartMedia card in JPEG format when the Record mode is set to SHQ, HQ or SQ. By downloading these images to a personal computer, users can edit them using graphics application software or view the images using an Internet web browser. M (Manual) Mode The user sets both the aperture and shutter speed. P (Program) Mode Also called Program AE mode. The camera automatically sets the best shutter speed and aperture for the shot. PAL (Phase Alternating Line) In Europe, PAL television signals are normally used. North America and Japan use NTSC signals. Pixels A pixel is the smallest unit (dot) used to make up an image. Clear large-sized printed images require millions of pixels. S (Shutter Priority) Mode Also called Shutter Priority AE mode. The user selects the shutter speed and the camera automatically varies the aperture so that the picture is taken with the best exposure. TFT (Thin-Film Transistor) Color Monitor A color Monitor constructed using thin-film technology. TIFF (Tagged Image File Format) An uncompressed format used for saving highly-detailed black & white or color image data. TIFF image files can be handled by software programs for scanners and graphics applications. TTL (Through-The-Lens) System To help adjust exposure, a light receptor built into the camera directly measures the light passing through the lens. 199
