sometimes termed dots per inch, this represents resolution
the measure of the sharpness (that is, the density of illuminated points) on a television display screen.
The number of pixels captured per inch by a scanner. This is a more accurate rate term than dpi (dots per inch) when applied to scanners because scanners capture pixels.
A measure of the density of scanned information in an image. The finer the optics of the scanner, the higher the scan resolution.
Pixels per inch (PPI) is a measure of the sharpness of a television display screen.
The number of pixels in a rastar image that occur in one line along one inch. The greater the pixels, the higher the resolution.
Pixels per inch (PPI) or pixel density is a measurement of the resolution of a computer display, related to the size of the display in inches and the total number of pixels in the horizontal and vertical directions. This measurement is often referred to as dots per inch, though that measurement more accurately refers to the resolution of a computer printer. PPI may also be used to describe the resolution of an or digital camera; in this context, it is synonymous with samples per inch.
