The pixels, or color samples, that form a digitized image (such as a JPEG file used on a web page) may or may not be in one-to-one correspondence with screen pixels, depending on how a computer displays an image. In computing, an image composed of pixels is known as a bitmapped image or a raster image.
The Million Dollar Homepage is a website conceived in 2005 by Alex Tew, a student from Wiltshire, England, to raise money for his university education. The home page consists of a million pixels arranged in a 1000 × 1000 pixel grid; the image-based links on it were sold for $ 1 per pixel in 10 × 10 blocks. The purchasers of these pixel blocks ...
A web beacon is any of several techniques used to track who is visiting a web page. They can also be used to see if an email was read or forwarded or if a web page was copied to another website. [7] The first web beacons were small digital image files that were embedded in a web page or email. The image could be as small as a single pixel (a ...

Image resolution is the level of detail of an image. The term applies to digital images, film images, and other types of images. "Higher resolution" means more image detail. Image resolution can be measured in various ways. Resolution quantifies how close lines can be to each other and still be visibly resolved.
The display aspect ratio ( DAR) is the aspect ratio of a display device and so the proportional relationship between the physical width and the height of the display. It is expressed as two numbers separated by a colon ( x: y ), where x corresponds to the width and y to the height. Common aspect ratios for displays, past and present, include 5: ...
The aspect ratio of the pixels themselves is known as the pixel aspect ratio (PAR) – for square pixels this is 1:1 – and these are related by the identity: SAR × PAR = DAR. Rearranging (solving for PAR) yields: PAR = DAR / SAR. For example: A 640 × 480 VGA image has a SAR of 640/480 = 4:3, and if displayed on a 4:3 display (DAR = 4:3) has ...
16:9 is a widescreen aspect ratio with a width of 16 units and height of 9 units. Once seen as exotic, [1] since 2009, it has become the most common aspect ratio for televisions and computer monitors, and is also the universal standard image format for the universal 1080p, 2160p and 4320p formats. 16:9 or "sixteen-nine" is the universal ...
