Patent ID: 8659585

Claim:
A projector apparatus, comprising: a projection unit that projects an image onto a projection surface; a reflectance distribution detection unit that detects a reflectance distribution at the projection surface; an ambient light pattern distribution image obtaining unit that obtains an ambient light pattern distribution image which indicates a density distribution of a base pattern at the projection surface caused by an ambient light; a smoothing unit that smooths the ambient light pattern distribution image; an input unit that inputs image data; an ambient light pattern correction image generating unit that generates an ambient light pattern correction image based upon the ambient light pattern distribution image, the ambient light pattern distribution image having been smoothed by the smoothing unit and the reflectance distribution detected by the reflectance distribution detection unit; a correction unit that corrects the input image data based upon the ambient light pattern correction image and input/output characteristics of the projection unit; and a control unit that controls the projection unit so as to project the image based upon the image data having been corrected.
