Abstract:
1. A video display apparatus comprising: an input unit that receives a video signal; a removing unit that removes DC components from the video signal received by said input unit; an integrating unit that generates an integration signal by integrating the video signal with said DC components removed by said removing unit; a subtracting unit that subtracts the integration signal generated by said integrating unit, from the video signal received by said input unit; a display unit that displays video in accordance with the video signal undergoing subtraction at said subtracting unit; and a measuring unit that measures a non-activation time, said non-activation time comprising a time from when a current supply to said display apparatus is stopped, until the current supply is restored, in which said display unit is not activated, wherein said removing unit removes said DC components which are calculated based on an average value of a brightness of the video signal in a frame period, and wherein said subtracting unit adjusts an amplitude of the integration signal in accordance with the non-activation time measured by said measuring unit, and subtracts the integration signal whose amplitude is adjusted from the video signal.
