Compression rate Compression is a method of reducing file size by abbreviating some contents of data, and compression rate denotes the amount of compression. The actual effect of the selected compression rate could vary with the content of the image. The numbers for the compression rate selected with this camera provide only a general scale for reference and are not precise measurements. DCF (Design rule for Camera File system) A standard for image files by the Japan Electronics and Information Technology Industries Association (JEITA). Depth of Field Depth of Field refers to the distance from the nearest to the furthest point of perceived "sharp" focus in a picture. Digital ESP (Electro-Selective Pattern) Light Metering This determines the exposure by splitting the image into 49 areas and metering and calculating the light levels in each area. DPOF (Digital Print Order Format) This is for saving desired print settings on digital cameras. By entering which images to print and the number of copies of each, the user can easily have the desired images printed by a printer or print lab that supports the DPOF format. Eclipsing (Vignetting) This refers to when an object obscures part of the field of view so that the whole subject is not photographed. Vignetting also refers to when the image seen through the viewfinder does not exactly match the image shot through the objective lens, so the photographed image includes objects not seen through the viewfinder. In addition, vignetting can occur when an incorrect lens hood is used, causing shadowing to appear in the corners of the image. EV (Exposure Value) A system for measuring exposure. EV0 is when the aperture is at F1 and the shutter speed is 1 second. The EV then increases by 1 each time the aperture increases by one F stop or the shutter speed increases by one increment. EV can also be used to indicate brightness and ISO settings. Exposure The amount of light used to capture an image. The exposure is determined by the length of time the shutter is open (shutter speed) and the amount of light that passes through the lens (aperture). Image pickup device This converts light passing through the lens into electrical signals. On this camera, light is picked up and converted into RGB signals to build a single image. Imager contrast detection system Focusing method based on the contrast of the image of the subject captured on the image pickup device. ISO International abbreviation for International Organization for Standardization. The sensitivity setting used in digital cameras is based on the same ISO standard used for film sensitivity. The sensitivity is denoted as shown in "ISO 100". Higher ISO values indicate greater sensitivity to light, so images can be exposed even in low-light conditions. JPEG (Joint Photographic Experts Group) A compression format for color still images. Photographs (images) shot using this camera are recorded onto the card in JPEG format when the Record mode is set to a setting other than 13 [RAW]. 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. 134 EN Information
