Image processing apparatus, image processing system, and image processing method

An image processing apparatus which receives from a modality, an image signal to be output to a displaying unit of the modality and outputs a standardization image signal obtained by standardizing the image signal to be output, the image processing apparatus comprising:

• a reference image signal outputting unit that outputs a reference image signal in which color information of a plurality of colors is included in a chart image in a display plane or a time axis;
• a color display information detection unit that detects color display information of an image displayed on the displaying unit based on the reference image signal;
• a profile generation unit that generates a display characteristic profile of the displaying unit using the detected color display information and the color information of the chart image;
• a display characteristic correcting unit that generates a color correction image signal obtained by correcting the image signal to be output which is input from the modality based on the display characteristic profile;
• and
• a standardization processing unit that converts the generated color correction image signal to the standardization image signal.
