Dots per inch. A close-up of the dots produced by an inkjet printer at draft quality. Actual size is approximately 1⁄4 by 1⁄4 inch (6 by 6 mm). Individual coloured droplets of ink are visible; this sample is about 150 DPI. Dots per inch ( DPI, or dpi [1]) is a measure of spatial printing, video or image scanner dot density, in particular ...
The difference is that whilst D1 has a 4:3 aspect ratio 960H has a 16:9 widescreen aspect ratio. The extra pixels are used to form the increased area to the sides of the D1 image. The pixel density of 960H is identical to standard D1 resolution so it does not give any improvement in image quality, merely a wider aspect ratio.
Retina display is a branded series of LCDs and OLED displays by Apple Inc. that have a higher pixel density than traditional displays. [1] Apple has registered the term "Retina" as a trademark with regard to computers and mobile devices with the United States Patent and Trademark Office and Canadian Intellectual Property Office.
Scanners and cameras. "PPI" or "pixel density" may also describe image scanner resolution. In this context, PPI is synonymous with samples per inch. In digital photography, pixel density is the number of pixels divided by the area of the sensor. A typical DSLR, circa 2013, has 1–6.2 MP/cm 2; a typical compact has 20–70 MP/cm 2 .
DCI-P3 is a color space first defined in 2005 as part of the Digital Cinema Initiative, to be used for digital theatrical motion picture distribution [1] (DCDM [2] ). Display P3 is a variant developed by Apple Inc. for wide-gamut displays.
16:10 (1.6:1) is an aspect ratio commonly used for computer displays and tablet computers. It is equal to 8/5, close to the golden ratio ( ), which is approximately 1.618. Video editing applications are commonly designed to allow editing of 16:9 content with the editing interface occupying the lower tenth of the display, allowing editing using ...
In Windows 3.1, the DPI setting is tied to the screen resolution, depending on the driver information file.) When a custom system DPI is specified, the built-in UI in the operating system scales up. Windows also includes APIs for application developers to design applications that will scale properly.
Lines per inch ( LPI) is a measurement of printing resolution. A line consists of halftones that is built up by physical ink dots made by the printer device to create different tones. Specifically LPI is a measure of how close together the lines in a halftone grid are. The quality of printer device or screen determines how high the LPI will be.
