    • The endoscope apparatus includes an illumination unit for irradiating at least three kinds of illumination light having different wavelengths including standard light, first and second reference light onto a biological object, a switching unit for periodically switching the illumination light, an imaging unit for capturing image data by the illumination light in each imaging frame, and an acquisition unit for acquiring biological function information from the captured image data. The irradiation order of illumination light is switched at least in order of the first reference light, the standard light and the second reference light, a standard image by the standard light and reference images by the reference light are acquired, and the biological function information is calculated based on the standard image and the reference images.
    • 所述内窥镜装置包括照射单元,用于将具有标准光,第一和第二参考光的不同波长的至少三种照明光照射到生物体上,用于周期性地切换照明光的切换单元,用于捕获图像数据的成像单元 通过每个成像帧中的照明光,以及用于从捕获的图像数据获取生物功能信息的获取单元。 照射光的照射次序至少按照第一参考光,标准光和第二参照光的顺序切换,通过标准光进行标准图像,并且获取参考光的参考图像,生物学功能信息是 基于标准图像和参考图像计算。
