An endoscope apparatus capable of transmitting an endoscope image as an optical signal includes: an electronic component that includes a reception circuit configured to receive an electric signal outputted from an image pickup device and supply the electric signal to a conversion device; a printed board provided with the electronic component; a shielding member that covers at least the reception circuit; a first path via a ground connection line that is provided for the electronic component, and electrically connects the shielding member to a ground; and a second path via a conductive portion that electrically connects the shielding member to the ground, wherein an impedance of the second path is lower than an impedance of the first path.

Endoscope apparatus for transmitting an endoscope image as an optical signal

An endoscope power supply system includes an endoscope including an imaging unit that images an object, a housing apparatus to which the endoscope is detachably connected, a plurality of power source units that are provided in the housing apparatus and configured to output electric power different from one another, switches each provided in an output stage of each of the power source units of the housing apparatus and formed of two FETs that are back-to-back connected, and a controller that is provided in the housing apparatus, selects a power source unit necessary to operate the endoscope from the power source units, and controls the switches to output electric power generated by the selected power source unit to the endoscope.

Endoscope system with power supply system

A solid-state imaging apparatus includes an imaging unit that images a subject to generate a plurality of pieces of image data having information corresponding to different types of color components at same pixel positions, an operation mode setting unit that sets an operation mode of the imaging unit, a thinning rate setting unit that sets a thinning rate relative to each of the plurality of pieces of image data of the different types of color components in accordance with the operation mode, a thinning processor that performs thinning processing relative to each of the plurality of pieces of image data of the different types of color components generated by the imaging unit in accordance with the thinning rate, and a transmission unit that transmits the plurality of pieces of image data of different types of color components subjected to the thinning processing.

Solid state imaging apparatus and imaging method

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

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.
