摘要： In imaging an oxygen saturation level of blood, measurement light having a wavelength of 450 to 500 nm, B light, G light, and an R light are sequentially taken out from a xenon lamp (30a). An internal body portion is imaged under irradiation with the measurement, B, G, and R light to obtain image data B1, B2, G2, and R2, respectively. A correlation memory (84) stores first and second correlations (84a, 84b), each being a correlation among the oxygen saturation level and intensity ratios between the image data B1 and G2 and between the image data R2 and G2. When a cumulative lighting time of the xenon lamp (30a) is less than a certain value, the oxygen saturation level is calculated using the first correlation (84a). When the cumulative lighting time equals or exceeds the certain value, the oxygen saturation level is calculated using the second correlation (84b).

摘要： In a special mode, a first frame image including a blue signal B1, a green signal G1, and a red signal R1 is captured in a first frame period. In a second frame period, a second frame image including a blue signal B2, a green signal G2, and a red signal R2 is captured. An oxygen saturation level calculator (86) calculates an oxygen saturation level of each pixel based on signal ratios B1/G2 and R2/G2, and sequentially outputs obtained special images on a monitor (14). Whenever the special image is produced, a signal ratio R2/R1 is calculated. When the signal ratio R2/R1 exceeds a threshold value, a warning sign "! !" (14a) is displayed. When the signal ratio R2/R1 is larger than a predetermined range S, a warning sign "HIGH StO 2 " (14b) is displayed. When the signal ratio R2/R1 is smaller than the range S, a warning sign "LOW StO 2 " (14c) is displayed.

摘要： First illumination light (BN) 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 (BB) of a second wavelength range different from the first wavelength range is projected into the 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.
