Along with the recent rapid penetration of personal computer, internet, digital camera, etc., full color images have become widely handled in digital form by various classes of users. In such a trend, technologies for color management system (CMS), printing, hardcopy output, image transmission, image compression, etc. are highlighted, and their refinements are on way to achieve higher image qualities.In the research activities in image technologies, the significance of high precision standard pictures is self-evident as they facilitate the evaluation of image processing algorithm, the accurate comparison of image output devices, etc.In April 1997, the activity of the Committee for Standard High Precision Pictures (Note 1) has resulted in the preparation of high resolution standard pictures characterized by that they are expressed by 16bit XYZ data as well as 8bit CIELAB data and Calibrated RGB data.The set of pictures named SHIPP consists of four full color natural scenes and a computer-generated chart, each expressed in three color spaces, i.e., XYZ, CIELAB, and Calibrated RGB. A detailed description of the last color space will be given later. The image data are formated according to TIFF6.0 and recorded in a CD-ROM.
