摘要： In a special mode, a superficial wavelength set having plural types of narrow band light in a blue wavelength band of 400 to 500 nm is chosen. The plural types of narrow band light are successively applied to an internal body portion. A CCD captures images of the internal body portion under the narrow band light. A blood information calculation section calculates an oxygen saturation level of hemoglobin in a blood vessel based on an image signal. A comparison section compares the calculated oxygen saturation level with a predetermined threshold value. When the oxygen saturation level is less than the threshold value, a hypoxic region detection signal is outputted to a wavelength set switching section. The wavelength set switching section switches from the superficial wavelength set to a middle wavelength set and to a deep wavelength set, so the oxygen saturation levels at middle and deep depths are measured.

摘要： First illumination light of a first wavelength range, in which light absorption coefficient of blood hemoglobin varies with oxygen saturation thereof, is projected into a test subject body, to capture a first image signal from the first illumination light as reflected from inside the test subject body. Then second illumination light of a second wavelength range different from the first wavelength range is projected into a test subject body, to capture a second image signal from the second illumination light as reflected from inside the test subject body. A subject image of the test subject is produced from the second image signal. Oxygen saturation levels of the test subject are calculated using the first and second image signals. According to the calculated oxygen saturation levels, color properties of the subject image are changed to produce an oxygen saturation image.

摘要： In a special mode, a superficial layer wavelength set, a middle layer wavelength set, and a deep layer wavelength set are selected successively. Each wavelength set is composed of 3 different types of narrowband light applied successively to an internal body portion. A wavelength set table specifies the number of repetitions of each wavelength set. A controller controls a wavelength band switching element to apply every type of the narrowband light of each wavelength set, and to apply each wavelength set for the number of repetitions specified by the wavelength set table. A CCD captures images of the internal body portion under illumination of the narrowband light of the respective wavelength sets.

摘要： First to third lights are applied to a body cavity from a light source. The first and second lights have different wavelength ranges. Each of the first and second lights varies in absorbance in accordance with oxygen saturation of hemoglobin. The third light is a reference light used for comparison with the first and second lights. A monitoring section monitors a first light quantity ratio between the first and third lights and a second light quantity ratio between the second and third lights. A controller controls the light source such that first and second light quantity ratios reach their respective standard values. First to third data are obtained from images captured with illumination of the three lights, respectively. Vessel depth information and oxygen saturation information are obtained simultaneously from a first brightness ratio between the first and third data and a second brightness ratio between the second and third data.
