Patent ID: 7093941

Claim:
A video display apparatus that irradiates light from a light source onto a display component of transmission or reflection type having a light modulating function to display video, the video display apparatus comprising: APL detection means for detecting an average picture level of an input video signal; light amount control data production means for producing light amount control data for controlling an amount of the light irradiated onto the display component on the basis of the average picture level detected by the APL detection means; and light amount control means for controlling the amount of the light irradiated onto the display component on the basis of the light amount control data, wherein the light amount control data production means produces the light amount control data such that the amount of the light irradiated onto the display component is controlled so as to be constant when the average picture level detected by the APL detection means is within a range from 0 to a first predetermined value greater than 0 and so as to continuously increase with an increase of the average picture level detected by the APL detection means when the average picture level is in a range of more than the first predetermined value.
