Abstract

See full text

A circuit apparatus is used in a laser projector that projects an image onto a projection surface by using laser beams having different wavelengths or a plurality of colors. The circuit apparatus includes a distortion correction circuit and an output circuit. The distortion correction circuit performs distortion correction on a color basis on display image data corresponding to the plurality of colors. The output circuit outputs the display image data as a result of the distortion correction. The distortion correction circuit performs the distortion correction on a color basis by using warp parameters different from one another among the plurality of colors.
