10. page 10 Introduction to Digital Imaging Colby Caldwell Resolution >Image Resolution Number of pixels (in both height and width) making up an image. The higher the resolution of an image, the greater its clarity and definition. >Output Resolution The number of dots per inch (dpi) used to display an image on a display device (monitor) or in print.

11. page 11 Introduction to Digital Imaging Colby Caldwell Resolution: Units of Measure >Pixel The picture elements that make up an image, similar to grains in a photograph or dots in a half-tone. Each pixel can represent a number of different shades or colors, depending upon how much storage space is allocated for it. >DPI Dots per inch. A measurement of the scanning resolution of an image or the quality of an output device. Expresses the number of dots a printer can print per inch, or monitor can display, both horizontally and vertically. A 600-dpi printer can print 360,000 (600 x 600) dots on one square inch of paper.
