摘要： An electronic endoscope system is composed of an electronic endoscope, a light source apparatus, and a temperature converter. The electronic endoscope has a CMOS sensor in a distal portion of an insert section to be inserted into a patient's body cavity. Illumination light from the light source apparatus is applied to the body cavity through the distal portion. The temperature converter obtains an average pixel value of an optical black (OB) region out of an imaging signal from the CMOS sensor, and converts the average OB pixel value into a temperature of the CMOS sensor on a frame-by-frame basis with the use of data in a temperature conversion table. The table represents a relationship between the average OB pixel value and the temperature of the CMOS sensor. Light quantity of the illumination light is adjusted in accordance with the temperature of the CMOS sensor to prevent deterioration of image quality.

摘要： In a search mode of an electronic endoscope system, ordinary light images and special light images are captured from a body cavity respectively under white light and special light. Simultaneously, biological information on the body cavity is acquired from image signals obtained under the special light. The ordinary and special light images are associated with the acquired biological information and stored in an image accumulator. By pressing a lock-on switch while confining a target in an area designating frame on an ordinary image on a monitor, the target is designated and biological information on the target is determined. Thereafter, biological information associated with the latest image in the image accumulator is compared with the biological information on the search target. If the latest image contains an area having the same biological information as the search target, the area designating frame is displayed on that area on the monitor.

摘要： An electronic endoscope includes an illumination unit, an imaging unit and an image generating unit. The illumination unit switches among plural light beams having different spectra so as to illuminate a subject. The light beams include white light and excitation light for exciting the subject to produce fluorescence. The imaging unit includes a solid-state imaging device, and an objective optical system. The objective optical system guides, to the solid-state imaging device, light returning from the subject which the illumination unit illuminates. The image generating unit generates image data based on image signals output from the imaging unit. The solid-state imaging device further includes a sensitivity adjusting unit that only lowers sensitivity, to the excitation light, of pixels which are sensitive to the fluorescence among a plurality of pixels of the solid-state imaging device. The light guided by the objective optical system is incident directly onto the solid-state imaging device.
