Abstract
Disclosed are an apparatus and method for projecting images to prevent the distortion of images when images are projected on a colored projection screen. The apparatus includes a device characteristic storage unit storing criterion projection characteristic information obtained when white light, black light and colored light are projected onto a criterion projection screen, a first image converter to convert received images into processed images by reflecting criterion projection characteristic information to received images, an image characteristic obtaining unit to obtain object projection characteristic information by projecting white light and black light onto an object projection screen, an image improvement unit to convert processed images into improved images by reflecting object projection characteristic information to processed images, and a second image converter to convert improved images into output images by reflecting criterion projection characteristic information and object projection characteristic information to improved images.
