Abstract: A light source device for an endoscope is provided. The light source device comprises a light source unit that supplies illumination light to an incident end face of a light guide member, which is laid inside an endoscope. The light source unit comprises a plurality of reflecting board members. Each reflecting board member has at least one light emitting diode. The plurality of reflecting board members are assembled into a concaved open polyhedron, so that the light emitted from the light emitting diodes are concentrated onto the incident end face of the light guide member.

Abstract: An electronic endoscope system includes an image pickup device provided at a distal end of an insertion portion; an image signal processing device; a main light source; an auxiliary light source which emits less amount of light than the light emitted from the main light source; and a light guide member which guides illumination light emitted from one of the main light source and the auxiliary light source to the distal end of the insertion portion to thereby emit the illumination light from the distal end. When the auxiliary light source emits the illumination light instead of the main light source, the image signal processing device sets the gain of the signal output from the image pickup device to a value higher than the gain of the signal when the main light source emits the illumination light, in order to process the image signal.

Abstract: An electronic endoscope apparatus has a moving-image displayer that reads image-pixel signals from an image sensor at predetermined time intervals to display a moving-image, a light-amount adjuster that adjusts an amount of light for illuminating a subject, and a still-image recorder that performs a series of actions for recording a still image. The still-image recorder is capable of reading the image-pixel signals at a still-image electronic shutter speed, which corresponds to a reading time interval shorter than the predetermined time interval. When the series of actions is started, the still-image recorder controls the light-amount adjuster such that the light-amount becomes a standard light-amount corresponding to the recording of the still image. Then, the still-image recorder performs a recording process in accordance with the still-image electronic shutter speed when the light-amount becomes the standard light-amount.

Abstract: Disclosed is a diagnosis supporting system that acquires a reference image signal of a subject that is illuminated with visible light and a fluorescent image signal of the subject that is excited by irradiation with excitation light, calculates a difference between brightness level of a pixel in the reference image signal and brightness level of a pixel in the fluorescent image signal at the corresponding position for all of target pixels and generates an observation image signal by converting the pixels in the reference image signal whose differences are larger than a predetermined value into red pixels. In the case of high contrast, all of the pixels become target pixels to be processed. In the case of low contrast, the number of the target pixels is reduced to null of all the pixels.
