<P>PROBLEM TO BE SOLVED: To provide a projector generating further correct coordinate information by appropriately adjusting exposure, and the like. <P>SOLUTION: This projector 100 is configured to include: a projection portion 190 for projecting a first image to a projection object region; an imaging portion 130 for imaging the projecting object region in projecting the first image to generate a first captured image, and imaging the projection object region in projecting a monochromatic image with automatic exposure to generate a second captured image; an imaging control portion 110 for changing, when a luminance value of a line segment in the first captured image is not in a predetermined range, an exposure set value based on the luminance value and an original exposure set value, and causes the imaging portion 130 to image the projection object region at the exposure set value to regenerate the first captured image; a first coordinate information generation portion 140 for generating first coordinate information representing the coordinates of the line segment based on the first captured image; and a second coordinate information generation portion 142 for generating second coordinate information representing coordinates of a border line of the projection object region based on the second captured image. <P>COPYRIGHT: (C)2011,JPO&INPIT |
