PURPOSE:To perform the evaluation due to color data relatively little in the fluctuation due to a photographing condition by converting color medical image data to hue and saturation data and plotting the same on a chromaticity diagram. CONSTITUTION:Digital image data is inputted from a color eyeground image input apparatus 2 and separated into three colors of R, G, B to be stored in an image memory 3 and displayed on a television monitor 5. A operator looks the monitor 5 to set an image region converted to chromaticity, for example, a shading part D using a command input part 4. The data of a hue H and saturation S are calculated from the respective density data of R, G, B with respect to the individual pixel of the image within the set region to be plotted on the chromaticity diagram of the television monitor 5 at the position corresponding to chromaticity (H, S). At this time, for example, the hue is plotted on the circumference of a horseshoe shape and the center of the horseshoe shape is set to the axis of saturation data. By this constitution, color data can be extracted from a digital medical image. |
