Scanning, Progressive
Scanning, Progressive – a) A rectilinear scanning process in which the distance from center to center of successively scanned lines is equal to the nominal line width. b) A display mode for electronic imaging in which all of the scanned lines are presented successively, and each field has the same number of lines as a frame. Also known as sequential scanning. For a given number of active vertical lines per frame, and a given frame rate, progressive scanning requires the same bandwidth as interlaced scanning. When compared at a given field rate, progressive scanning requires twice the bandwidth of 2:1 interlaced scanning. Note: Most image processing in electronic post-production requires that a progressive scanned image first be captured or created. The image information may have originated in progressive scanning, or it may have been interpolated from an origination in interlaced scanning.
