摘要： An endoscope 100 includes a first light source 45 that emits white illumination light, a second light source 47 that emits narrow-band light and an imaging section that has an imaging device 21 having plural detection pixels and images a region to be observed. The imaging section is caused to output a captured image signal including both a return light component of the white illumination light from the region to be observed by and a return light component of the narrow-band light the white illumination light. From the captured image signal, the return light component of the narrow-band light is selectively extracted, and a brightness level of the extracted return light component of the narrow-band light is changed by changing a light amount of light emitted from the second light source 47.

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.

摘要： An endoscope includes an elongated tube. An objective lens system is disposed in the elongated tube, for passing image light from an object. A fiber optic image guide includes plural optical fibers bundled together, has a distal tip, is inserted through the elongated tube, for transmitting the image light focused on the distal tip by the objective lens system in a proximal direction. A displacing device displaces the distal tip laterally and periodically upon receiving entry of the image light being focused by use of a piezoelectric actuator positioned outside the distal tip. An image sensor creates images in plural set positions of the distal tip. First to fourth images among the plural images created consecutively are combined to form a first synthesized image. Then second to fifth images among the plural images without use of the first image are combined to form a second synthesized image.

摘要： An electronic endoscope system includes an electronic endoscope having a CMOS image sensor on the tip of an insertion section, a light source device for illuminating the interior of a patient's body, and a processing device for reading out image signals from the CMOS image sensor. The electronic endoscope system can operate with a standard imaging mode and a special imaging mode. When the time taken to read out the image signals from all the pixels in the standard mode is defined as T, the light source device in the special imaging mode emits illumination light in every first half period T/2 while switching a wavelength of the illumination light between two different wavebands. In every second half period T/2, the processing device reads out the image signals from the half of the pixels.
