Medical image processing device and medical observation system

A medical image processing device comprising:

• a first captured image acquisition circuit configured to acquire a first left-eye image and a first right-eye image having parallax each of which is obtained by capturing light from an observation target irradiated with light in a first wavelength band, the observation target emitting fluorescence when irradiated with excitation light in a second wavelength band different from the first wavelength band;
• a second captured image acquisition circuit configured to acquire a second left-eye image and a second right-eye image having parallax each of which is obtained by capturing the fluorescence from the observation target irradiated with the excitation light;
• a superimposed image generation circuit configured to superimpose corresponding pixels of the first left-eye image and the second left-eye image on each other to generate a left-eye fluorescence superimposed image and superimpose corresponding pixels of the first right-eye image and the second right-eye image on each other to generate a right-eye fluorescence superimposed image;
• a display control circuit configured to generate a display image from the first left-eye image, the first right-eye image, the second left-eye image, the second right-eye image, the left-eye fluorescence superimposed image, and the right-eye fluorescence superimposed image,
• wherein the display image includes a stereoscopically observable three-dimensional fluorescence superimposed image generated from the left-eye fluorescence superimposed image and the right-eye fluorescence superimposed image;
• a first image processor configured to execute image processing on the first left-eye image;
• a second image processor configured to execute image processing on the first right-eye image;
• a third image processor configured to execute image processing on the second left-eye image;
• a fourth image processor configured to execute image processing on the second right-eye image;
• a mode switching circuit configured to switch between a first observation mode or a second observation mode;
• and
• a control circuit configured to
• output the first left-eye image, the first right-eye image, the second left-eye image, and the second right-eye image to the first image processor, the second image processor, the third image processor, and the fourth image processor, respectively, in the first observation mode, and
• output four divided images divided from one of the first left-eye image and the first right-eye image to the first image processor, the second image processor, the third image processor, and the fourth image processor, in the second observation mode, and
• the superimposed image generation circuit is configured to generate the left-eye fluorescence superimposed image and the right-eye fluorescence superimposed image in the first observation mode.
