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. |

DETAILED DESCRIPTION It is an object of the invention to provide an endoscope-image processing apparatus capable of producing an endoscope image provided with characteristics suitable for diagnosis, on the basis of organism functional information such as a hemoglobin pigment and the like.
It is another object of the invention to provide an endoscope-image processing apparatus capable of producing an endoscope image which is provided with characteristics easy to discriminate or identify a lesion part under an initial condition.
According to the invention, there is provided an endoscope-image processing apparatus comprising imaging means for imaging a subject image, pigment-quantity distribution calculating means for producing distribution of at least one pigment quantity from the image produced by said imaging means, and emphasis means for replacing the pigment quantity by a pigment quantity enlarged in a quantity of shift from a reference value and thereafter, transforming the replaced pigment quantity to an endoscope image provided with the substituted pigment quantity to thereby perform emphasis of an image.
A value higher than the reference value is substituted for a higher pigment quantity, and a value lower than the reference value is replaced with a lower pigment quantity.
Thereafter, the pigment quantity is returned to an endoscope image to produce an endoscope image which has an emphasized image, whereby there is produced an endoscope image which is provided with characteristics of a normal endoscope image and which is characterized in that a lesion part is emphasized as to be conspicuous.
