The number of pixels in an area or on the screen.
Resolution is typically specified as pixels per scan line and scan lines per frame. Higher resolution images require more processing and greater storage requirements per image. In addition, monitor costs increase with resolution, particularly above about one million pixels. Different applications require different resolutions.
Industry:Software
A unidirectional source geometrically defined by its position and target.
Industry:Software
A number used to compare the amounts of light passed through optical systems, such as camera lenses. Transmission aperture takes into consideration both the f-stop (geometric aperture) and the amount of light absorbed or reflected in the optical system.
Industry:Software
An ATV proponent issued a patent for a data compression transmission scheme for HD signals. The Osborne compression system is said to allow channel-compatible but not receiver-compatible HDTV.
Industry:Software
Sequence of pictures, that all are frame pictures with frame DCT coding.
Industry:Software
A table listing the providers of each service in a transport stream. The SDT contains data describing the services in the system, i.e., includes names of services, the service provider, etc.
Industry:Software
A version of TIFF file format used by Kodak digital cameras to store non-image data with many different types of image data.
Industry:Software
The set of video coding algorithms that precedes the actual MPEG-4 video coding specification.
Industry:Software
The fine details in a video picture. A picture appears sharp when it contains fine details and has good contrast. Picture sharpness is easily lost during the recording/playback process. Advanced video enhancement equipment is used to improve picture sharpness, especially contrast, and can precompensate for potential losses which might alter an image during processing.
Industry:Software
The amount of resolvable detail in the vertical direction in a picture. It is usually expressed as the number of distinct horizontal lines, alternately black and white, which can be seen in a test pattern.
Vertical resolution is primarily fixed by the number of horizontal scanning lines per frame. Beyond this, vertical resolution depends on the size and shape of the scanning spots of the pickup equipment and picture monitor and does not depend upon the high-frequency response or bandwidth of the transmission medium or picture monitor.
