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： A CCD image sensor is fixed on a Y-direction stage that is supported on an X-direction stage. When a piezo driver supplies voltage to an X-direction piezo element and a Y-direction piezo element, the CCD image sensor is moved in X and Y directions. The X-direction position sensor and the Y-direction position sensor detects the position information of the CCD image sensor in X and Y direction respectively, and send the position information to the piezo driver. The piezo driver sets a target movement of the CCD image sensor, and detects the actual movement of the CCD image sensor from the position information. The piezo driver adjusts the output voltage to the X-direction piezo element and the Y-direction piezo element such that the target movement becomes the same as the actual movement.
