Claim One:
1. An image processing device used for a projector adapted to display an image by projecting the image on a projection surface comprising: a detection image generation section adapted to generate a detection image, the detection image being an image adapted to detect a state of a projection image displayed on the projection surface, the detection image including: (i) a plurality of detection image parts, and (ii) a background image adapted to cover respective peripheries of the detection image parts, wherein: each of the detection image parts includes a plurality of regions having respective luminance values different from each other, the background image has a luminance value lower than the luminance values of the detection image parts, and the detection image generation section changes a luminance distribution of each of the detection image parts of the detection image to be generated, and a size of each background image corresponding to each of the detection image parts, individually, so that a maximum value and a width of a luminance distribution of each of the detection image parts included in a taken detection image, which is taken by imaging the projection image generated by projecting the detection image projected on the projection surface, is approximated to a maximum value and a width of a luminance distribution of corresponding one of the detection image parts of the detection image.
