摘要： A light source device of an electronic endoscope system has first and second semiconductor lasers. In a vascular observation mode, one of the semiconductor lasers is used in a full light state (100% rated output) while the other is used in a reduced light state (for example, 10% rated output). First and second images of an internal body portion are captured with a color imaging device under illumination of two patterns, respectively. Correlation operation of pixel values of three colors is performed between the two images. Noise components, caused by the first or second semiconductor lasers in the light reduced state, are removed from the first and second images. An oxygen saturation level of blood in a blood vessel is calculated using the first and second images with the noise components removed.

摘要： In a blood information measuring apparatus, a plurality of types of light of a superficial layer wavelength set, a middle layer wavelength set, and a deep layer wavelength set are successively applied to a detected hypoxic region. A CCD captures an image under the light of each wavelength set, and an oxygen saturation image is produced independently from one wavelength set to another. A wavelength set determination section creates a histogram of each oxygen saturation image. The wavelength set determination section chooses one of the wavelength sets corresponding to the histogram having a maximum variance as an actual imaging wavelength set. Actual imaging operation is performed using the actual imaging wavelength set, and an oxygen saturation level of each pixel is calculated. The oxygen saturation level is reflected in the image, and the image is displayed on a monitor.

摘要： In a blood information acquisition mode for obtaining an oxygen saturation level of hemoglobin in a blood vessel, preliminary imaging and main imaging are performed. In the preliminary imaging, a normal internal body part is imaged. A blood information calculation section calculates an oxygen saturation level of each pixel. A changing section corrects standard reference data in accordance with a difference between an average of the oxygen saturation levels obtained in the preliminary imaging and a predetermined standard value of the oxygen saturation level. In the subsequent main imaging, corrected reference data is used to calculate an oxygen saturation level of each pixel corresponding to an internal body part being observed.

摘要： An image of a target portion is captured while first light beams are applied thereto. Thereby, a first image signal is obtained. The first light beams are in a wavelength range in which an absorption coefficient varies in accordance with a change in oxygen saturation of hemoglobin in blood. An image of the target portion is captured while second light beams in a broadband wavelength range are applied thereto. Thereby, second and third image signals are obtained. Oxygen saturation is calculated from the first to third image signals. Reliability of the oxygen saturation is calculated from one of the first to third image signals. Color difference signals each corresponding to the oxygen saturation is obtained from a color table. Each of the color difference signals is corrected in accordance with the reliability. An oxygen saturation image is generated based on corrected color difference signals and displayed.

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.
