Definition: The number of pixels per inch in an image, or the number of dots per inch used by an output device.
Definition: The particular pixel density of an image, or the number of dots per inch a device is capable of recognizing or producing. See "DPI" and "PPI. "
Definition: Refers to the sharpness and clarity of an image. The term is most often used to describe monitors, printers, and bit-mapped graphic images. In the case of dot-matrix and laser printers, the resolution indicates the number of dots per inch. For example, a 300-dpi (dots per inch) printer is one that is capable of printing 300 distinct dots in a line 1 inch long. This means it can print 90,000 dots per square inch. For graphics monitors, the screen resolution signifies the number of dots (pixels) on the entire screen. For example, a 640-by- 480 pixel screen is capable of displaying 640 distinct dots on each of 480 lines, or about 300,000 pixels. This translates into different dpi measurements depending on the size of the screen. For example, a 15-inch VGA monitor (640x480) displays about 50 dots per inch. Printers, monitors, scanners, and other I/O devices are often classified as high resolution, medium resolution, or low resolution. The actual resolution ranges for each of these grades is constantly shifting as the technology improves. Standard resolution is 640 x 480 pixels (H x V) and originates with the VGA standard first defined for the IBM PC. SVGA is the next step up in terms of resolution and covers 800 x 600. XGA define the 1024 x 768 resolution, while UXGA is used for 1280x1024 and 1600x1200. The higher the resolution the finer the image detail that can be seen.
Definition: A measure of how closely packed the dots in a bitmapped image are, often expressed in dots per inch (dpi) or lines per inch (lpi). The higher the number, the higher the quality. However, doubling the resolution of an image results in a computer file four times as large, requiring more hard disk space and computer memory to handle the higher quality image. Resolution is also used to describe how close together a computer printer can print dots in an image. Again, the larger the number, the higher the quality. It is important to know the capability of the printer's resolution before scanning an image in order to get enough information to print the best quality.
