ABSTRACT:
An endoscope apparatus used in combination with a near infrared light irradiation unit that irradiates near infrared light on a target irradiation section. White light and the infrared light are irradiated on a target observation area including the target irradiation section. The imaging means spectroscopically images a reflected light image of the target observation area, which is outputted as a spectral image signal. The storage section includes estimated matrix data. The IR image signal generation means generates an IR image signal constituted by an estimated value of reflected light intensity of the near infrared light by performing a matrix operation on the spectral image signal using the estimated matrix data and spectral matrix data of the near infrared light. The color image signal generation means generates a color image signal based on the spectral image signal and the IR image signal.
