An apparatus, method and medium outputting a wide gamut space image in which one or more parameters that are needed to convert an existing color space into a wide gamut space are experimentally determined and then are applied to an image. The apparatus includes a feature extraction module to extract one or more feature differences between a standard gamut and a wide gamut of an image, a color range setting module to set a hue range according to the extracted feature differences and one or more experimentally determined parameters, and a conversion module to convert the image according to the extracted feature differences, the experimentally determined parameters, and the hue range.

Apparatus, method and medium outputting wide gamut space image

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.
