An imaging device includes: an imaging unit configured to output an imaging signal; an illumination unit configured to emit respective beams of light of a plurality of colors; a color separation unit configured to separate the imaging signal into a plurality of signals corresponding to the plurality of colors; an interest color setting unit configured to set a color corresponding to a wavelength band of interest as an interest color; a comparison unit configured to compute a ratio between a detection value of a signal corresponding to an interest color set by the interest color setting unit and a detection value of a signal of another color corresponding to a wavelength band different from the wavelength band corresponding to the interest color; and a changing unit configured to change a light emission ratio between light corresponding to the interest color and light of the other color.

Imaging device and processing device

An endoscope system includes: an insertion portion; an illumination portion that emits a plurality of illuminating lights of different hues to each other; an image pickup portion that picks up an optical image formed by an objective optical system in a distal end portion of the insertion portion; a channel that opens in a distal end portion of the insertion portion; a laser probe that is inserted through the channel and has an irradiation portion in a distal end region; a hue range setting portion that sets a hue range of the laser probe in accordance with a hue of an illuminating light; an image analysis portion that detects a hue range portion in a color image obtained from the image pickup portion; and a control portion that permits laser output only in a case where the hue range portion is detected.

Endoscope system for controlling output of laser from laser probe

A video processor includes: a judgement section configured to judge whether an input is a 2D or 3D image signal; an LR synthesis section configured to embed left and right image signals into an image signal in a side-by-side format to output the signal if the input is the 3D image signal and configured to embed a 2D image signal into a position corresponding to one of the left and right in an image signal in a side-by-side format to output the signal if the input is the 2D image signal; and an image processing section configured to apply image processing to the image signal in the side-by-side format.

Video processor and activation method of video processor

An endoscope system includes: an endoscope including an insertion portion, an image pickup portion that acquires a plurality of images by time-sequentially picking up optical images of a subject by means of an objective optical system provided in a distal end portion of the insertion portion, and a channel that opens at the distal end portion of the insertion portion; a laser probe that is inserted through the channel; an image analysis portion that detects an area showing the laser probe with respect to each image; and a control portion that permits laser output only in a case where it is determined that the laser probe protrudes from the opening of the channel based on detection results with respect to the area showing the laser probe for a plurality of images that are time-sequentially consecutive.

Endoscope system that controls laser output of laser probe and control method for endoscope system

An endoscope signal processing apparatus has a first video signal generating circuit and a second video signal generating circuit which respectively generate a first video signal and a second video signal offering different resolutions depending on a first image capturing device and a second image capturing device respectively which are mounted in an endoscope removably connected to an endoscope connecting portion. The first and second video signals can be selectively output to an exterior through a common video signal output connector.
