Title: IMAGE ANALYSIS DEVICE, IMAGE ANALYSIS SYSTEM, AND METHOD FOR OPERATING IMAGE ANALYSIS DEVICE
Abstract:
The present invention includes: a region extraction unit 33 that sets a prescribed region as a region to be analyzed in each of a first image and a second image which are respectively obtained at timings before and after performing a predetermined action on a subject and are input from an image input unit 32 in a state where an endoscope is continuously inserted inside the subject; a distribution characteristic value calculation unit 34 that calculates a first distribution characteristic value by extracting color components of the region to be analyzed in the first image and that calculates a second distribution characteristic value by extracting color components of the region to be analyzed in the second image; and an image analysis unit 35 that calculates a degree of change of the second distribution characteristic value with respect to the first distribution characteristic value.
