Abstract: A projector according to the present invention comprises a lamp driving control circuit for driving an ultra-high pressure mercury lamp at a driving frequency which is changed within an allowable frequency range. For example, the lamp driving control circuit may randomly select a frequency within the allowable frequency range, or modulate the highest frequency within the allowable frequency range such that the frequency is reduced, to change the driving frequency.

Such flicker is less perceivable to human's eyes due to the human's visual characteristics.
