Patent ID: 7530695

Claim:
A projector, comprising: a light source unit; a light modulation element that modulates light from the light source unit on a basis of image data, an image produced by the image data being displayed in a plurality of regions; a light adjusting unit that adjusts an amount of light incident on the light modulation element from the light source unit; a control unit that controls the light modulation element and the light adjusting unit, the control unit calculating a range of luminance distribution and average luminance of the image data, the range of the luminance distribution including brightness data for each of the plurality of regions, adjusting the amount of light for the light adjusting unit according to the range of the luminance distribution and the average luminance of the image data and selectively controlling the light modulation element to correct display irregularity of the image data caused by an adjustment of the amount of light for the light modulation element for each of the plurality of regions according to the range of the luminance distribution and the average luminance of the image data; and a pair of lens arrays that are disposed between the light source unit and the light modulation element, the light adjusting unit having a light-shielding plate and a moving unit that moves the light-shielding plate.
