The term resolution is often considered equivalent to pixel count in digital imaging, though international standards in the digital camera field specify it should instead be called "Number of Total Pixels" in relation to image sensors, and as "Number of Recorded Pixels" for what is fully captured.
This chart shows the most common display resolutions, with the color of each resolution type indicating the display ratio (e.g., red indicates a 4:3 ratio).
A chart showing the number of pixels in different display resolutions. A display resolution standard is a commonly used width and height dimension (display resolution) of an electronic visual display device, measured in pixels.
The term "4K" is generic and refers to any resolution with a horizontal pixel count of approximately 4,000. [4]: 2 Several different 4K resolutions have been standardized by various organizations.
1080p progressive scan HDTV, which uses a 16:9 ratio. Some commentators also use display resolution to indicate a range of input formats that the display's input electronics will accept and often include formats greater than the screen's native grid size even though they have to be down-scaled to match the screen's parameters (e.g. accepting a 1920 × 1080 input on a display with a native 1366 ...
Any display device that advertises 1080p typically refers to the ability to accept a 1080p signal and display it with a native resolution of at least 1080 lines vertically (as well as the ability to upscale lower-resolution material to 1080p).
The ability of a lens to resolve detail is usually determined by the quality of the lens, but is ultimately limited by diffraction.Light coming from a point source in the object diffracts through the lens aperture such that it forms a diffraction pattern in the image, which has a central spot and surrounding bright rings, separated by dark nulls; this pattern is known as an Airy pattern, and ...
2K resolution is a generic term for display devices or content having a horizontal resolution of approximately 2,000 pixels. [1] In the movie projection industry, Digital Cinema Initiatives is the dominant standard for 2K output and defines a 2K format with a resolution of 2048 × 1080.
