PURPOSE: A device and method for correcting a projector image are provided to find distance information about a projection plane using a distance image camera in order to detect the surface shape of the plane and in order to identify surface conditions such as colors or materials and the condition of a peripheral lighting, thereby effectively correcting an output target image. CONSTITUTION: A device for correcting a projector image includes a distance image calculating part (102), a surface shape detecting part (103), a surface condition detecting part, a lighting condition detecting part, and an output image correcting part (106). The distance image calculating part outputs the calculation results of distance images from distance image cameras (101a-101n). The surface shape detecting part recognizes the surface shape of a projection plane using the results, and obtains geometric information. The surface condition detecting part analyzes the colors and materials of an independent projection circumstance image configured with images from actual image cameras in order to divide a screen into areas and in order to analyze the colors and materials for the respective areas. The lighting condition detecting part obtains the lighting information of a circumstance. The output image correcting part corrects an output image using the information.
