    Abstract: An endoscope system includes an endoscope including a control section, an insertion section, and a light guide member, a light source configured to emit light guided by the light guide member, a failure-cause detecting circuit configured to detect a pre-failure state that causes a failure of the endoscope, and a light source controller configured to control an output of the light source based on a detection result of the failure-cause detecting circuit. The failure-cause detecting circuit includes a cause predicting circuit configured to detect a second pre-failure state in which it is predicted that the endoscope reaches a first pre-failure state that directly causes the failure of the endoscope. The light source controller controls the output of the light source based on a detection result of the cause predicting circuit.

    Abstract: An imaging system includes an illumination portion, an imager, a reader, and an illumination controller configured to control an intensity of illumination light based on modulated illumination in a non-reading period. The modulated illumination has a first integrated light amount as a product of a variable intensity of a first pulse and an output period of the illumination light and a second integrated light amount as a product of a constant intensity of a second pulse and the output period. In the non-reading period, the illumination controller causes a predetermined light amount that is not larger than a maximum value of the first integrated light amount and is not smaller than a minimum value of the second integrated light amount to transit between the first integrated light amount and the second integrated light amount.

    Abstract: An observation apparatus includes an imager, a light source unit, an image processor and a light intensity adjusting section. The imager includes types of elements which generate a first signal when the elements receive light included in a sensitivity region. The light source unit includes light sources to emit narrow spectrum light, wavelengths of the light being different from one another and being set so that at least one of the wavelengths is included in each of the sensitivity regions. The image processor generates display data indicating a color image on the basis of the image data. The light intensity adjusting section separately adjusts respective light intensity of the light sources.

    Abstract: An illumination apparatus includes a first wavelength converter which absorbs part of the first excitation light and emits first wavelength-converted light, a second wavelength converter which absorbs part of the first excitation light and emits second wavelength-converted light, a reflector including a reflecting surface which is arranged to surround the members, and a holder which holds the members. A first region where light distribution angles of light emitted from the members have a predetermined value or less and a second region where the light distribution angle is less than the predetermined value are present in a region surrounded by the reflecting surface. The holder holds at least one part of the wavelength converter and at least one part of the second wavelength converter at the first region.

    Abstract: A light source apparatus includes a light conversion unit converting primary light into secondary light. The light conversion unit includes a light conversion member, a holder and a reflection member. The holder includes an incidence portion through which the primary light enters and an exit portion through which at least part of the secondary light exits in a direction crossing an optical axis of the primary light. The light conversion member is arranged on the optical axis of the primary light. Part of the secondary light allowed to exit from the light conversion member in a direction different from a direction toward the exit portion is reflected by the reflection member and exited from the exit portion. The ratio of reentering to the light conversion member is reduced.
