Pixel aspect ratio 1:1 Pixel aspect ratio 2:1. A Pixel aspect ratio (often abbreviated PAR) is a mathematical ratio that describes how the width of a pixel in a digital image compared to the height of that pixel. Most digital imaging systems display an image as a grid of tiny, square pixels.
The resolution of 960H depends on whether the equipment is PAL or NTSC based: 960H represents 960 x 576 (PAL) or 960 x 480 (NTSC) pixels. [29] 960H represents an increase in pixels of some 30% over standard D1 resolution, which is 720 x 576 pixels (PAL), or 720 x 480 pixels (NTSC). The increased resolution over D1 comes as a result of a longer ...
Four times as many pixels compared to the base resolution, i.e. twice the horizontal and vertical resolution respectively. Hex(adecatuple) (H) Sixteen times as many pixels compared to the base resolution, i.e. four times the horizontal and vertical resolutions respectively. Super (S), eXtended (X), Plus (+) and/or Ultra (U)
An array of 1280 × 720 on a 16:9 display has square pixels, but an array of 1024 × 768 on a 16:9 display has oblong pixels. An example of pixel shape affecting "resolution" or perceived sharpness: displaying more information in a smaller area using a higher resolution makes the image much clearer or "sharper".
It is exactly double the pixel count of QHD (2560 × 1440) in both dimensions for a total of four times as many pixels, and is one third larger than 4K UHD (3840 × 2160) in both dimensions for a total of 1. 77 times as many pixels.
An image that is 2048 pixels in width and 1536 pixels in height has a total of 2048×1536 = 3,145,728 pixels or 3.1 megapixels. One could refer to it as 2048 by 1536 or a 3.1-megapixel image. The image would be a very low quality image (72ppi) if printed at about 28.5 inches wide, but a very good quality (300ppi) image if printed at about 7 ...
The most common large format is 4 in × 5 in (10 cm × 13 cm), which was the size used by cameras like the Graflex Speed Graphic and Crown Graphic, among others. Less common formats include quarter-plate (3.25 in × 4.25 in (8.3 cm × 10.8 cm)), 5 in × 7 in (13 cm × 18 cm), and 8 in × 10 in (20 cm × 25 cm); the size of many old 1920s Kodak cameras (various versions of Kodak 1, 2, and 3 and ...
In the US, size names are often denoted with a code of the format nR, where the number n represents the length of the shorter edge in inches. In the normal series, the long edge is the length of the short edge plus 2 inches (10 in or less) or 3 inches (11 in and above).
