Abstract
Provided is an apparatus that includes an image projection section that performs an image projection process based on a PWM method, an output image control section that sets a portion of a single-frame output period of a view-use image as a period in which to output a pattern image to be used for calculating an image correction parameter, a correction parameter calculation section that calculates the image correction parameter with use of the pattern image captured by a camera in the pattern image output period, and an image correction section that performs a correction process on the view-use image with use of the image correction parameter. The output image control section controls the pattern image output period in such a manner that pixel values of the pattern image fall within a range from a minimum pixel value to less than a minimum significant pixel value of the view-use image.
