Abstract
To avoid the effect of blemishes in a CRT phosphor of a CRT film scanner a map is produced identifying areas of the phosphor that are blemished. When a line scan traverses a blemish the signal produced by that scan is inhibited and the area of film is rescanned with the film in a different position relative to the scanner.
