Problems solved by technology

However, the problem that arises is that vignetting may occur in the image because the light sensor in the light path may block the subject light
A solution to such a problem is not disclosed in JP-A 2011-183099 or JP-A 2011-041758

Embodiment Construction

[0061] exist figure 1 In the example, an endoscope system 10 includes an endoscope 11 , a processing device 12 , a light source device 13 and a monitor display panel 14 . The endoscope 11 images a subject in a body cavity, and generates image signals. The processing device 12 generates an object image from the image signal. The light source device 13 supplies the endoscope 11 with light for illuminating a subject. The display panel 14 displays images. The console unit 15 is a user interface of the processing device 12 and includes various elements such as a keyboard, a mouse, and the like.

[0062] Endoscopic system 10 is operable in a normal imaging mode (color image mode) and a special imaging mode. In normal imaging mode, the object of interest is imaged with white light. In a special imaging mode, special light is used to image blood vessels in the region of interest. In special imaging modes, patterns of blood vessels or oxygen saturation levels are recognized to di...

Abstract

The invention discloses a light source apparatus and an endoscope system. The light source apparatus for supplying an endoscope with light includes at least one light source unit for generating the light. A transparent light homogenizer includes an entrance end face, disposed on a proximal side in an optical axis direction, for receiving entry of the light, an exit end face, disposed on a distal side in the optical axis direction, for exiting the light traveling from the entrance end face, and a reflective interface, formed in a tubular shape between the entrance end face and the exit end face, for total reflection of the light in an internal manner and for directing the light in the optical axis direction. At least one photo sensor is disposed on the reflective interface, for measuring a light amount of the light.

Description

technical field [0001] The present invention relates to a light source device and an endoscope system. More specifically, the present invention relates to a light source device and an endoscope system in which light quantity can be measured only in the light source device with a simplified structure. Background technique [0002] Endoscope systems for diagnosis of body cavities are widely used in the medical field. An endoscope system includes an endoscope, a light source device, and a processing device. An endoscope includes an elongated tube and a tip. The elongated tube enters the body cavity. The tip device is disposed at the distal end of the elongated tube, images a subject in the body cavity, and outputs image signals. The light source device supplies the endoscope with light for illumination. The processing device processes image signals output by the endoscope. An illumination window and an imaging window are formed in the terminal device. Lighting windows em...
