Abstract:
The motion data preparation system comprising: one or a plurality of color cameras for shooting motions of a subject in a state that color markers are attached to the subject or that part of the subject is determined as a color marker;color-integrated image data generating means for, through a decoding process of color image signals based on image outputs from the color cameras, integrating and consolidating color information included in each of the image signals into a specific number of color groups, and thereby generating image data (hereinafter, referred to as color-integrated image data) having data pieces smaller in number than the color image signals; marker specified-color extracting means for extracting data of pixels having a color previously specified as a color of the color marker (hereinafter, referred to as marker specified color) with respect to the generated color-integrated image data; and marker-position-data calculating and outputting means for calculating a color marker position of the shot subject based on the extracted marker specified-color pixel data and outputting, as motion data of the subject, marker position data obtained as a result of the calculation, further comprising: information separating means for, through a process of decoding the color image signal, separating the color image signal into luminance information, which is information on luminance, and chromatic information, which is information on chromatic components; and chromatic information correcting means for correcting the chromatic information by the luminance information, wherein the color-integrated image data generating means generates the color-integrated image data by integrating and consolidating mainly the separated chromatic information into a specified number of color groups.
