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 the actual contrast and brightness settings to obtain corrected histogram data, a total beam current is predicted (18) from the corrected histogram data, and a correction signal is derived (20) from the predicted total beam current and making said correction signal effective in the processing and normalizing step (12).
