ABSTRACT:
In an endoscope apparatus, an image processing unit for an endoscope, and a method of emphasizing an endoscope image, conversion processing is performed in which an amount of pigment, such as a hemoglobin pigment, is calculated from the endoscope image which is detected by the use of the endoscope, by a pigment calculating circuit. The amount of pigment is substituted for an amount of pigment in which an amount of shift from a value such as average of the amount of pigment is enlarged, and the amount of pigment is returned to the endoscope image having an amount of pigment in which the amount of shift from an average is enlarged, whereby tone of most parts having the amount of pigment of the average is not changed to an original endoscope image, but the endoscope image in which tone of a portion having the amount of pigment which is shifted from the average is emphasized is generated.
