  • Preventing doming phenomena
    Patent number: 6741295
    Abstract: In a method of preventing doming phenomena, luminance histogram distribution values are obtained (10) from a luminance signal, the various luminance histogram distribution values are processed and normalized (12), the luminance histogram distribution values are processed (16) to correct for at least actual contrast and brightness settings to obtain corrected histogram data, a beam current is predicted (18) from the corrected histogram data, and a correction signal is derived (20) from the predicted beam current and making said correction signal effective in the processing and normalizing step (12).
    Type: Grant
    Filed: June 11, 2001
    Date of Patent: May 25, 2004
    Assignee: Koninklijke Philips Electronics N.V.
