    摘要: An illumination device for an endoscope includes illumination means for coupling light into a light guide. The illumination means has an LED matrix array having a plurality of LED pixels forming an emission area, and further includes a light guide port associated with the illumination means for positioning a light-guiding transmission area, which is disposed at an end of the light guide. The device also includes LED pixels configured as sensor elements configured to detect LED pixels of the emission area that are directed at non-light-guiding portions of the light guide, and wherein the device has a control unit which is configured to selectively operate the LED pixels of the LED matrix array for coupling light into the light guide in such a manner that at least some of the LED pixels directed at the non-guiding portions of the light guide in the main emission direction are operated at lower power or deactivated.

    摘要: One embodiment of the present invention is a processor for an endoscope configured to process a captured image of a biological tissue. This processor for an endoscope includes: a light source device that emits a light for illuminating a biological tissue; a spectrum sensor that acquires an optical spectrum of an emitted light from the light source device; and an adjustment unit that adjusts the optical spectrum of the emitted light from the light source device so that a difference between the optical spectrum acquired by the spectrum sensor and a predetermined target spectrum is reduced.

    摘要: An image sensor includes: a pixel unit including pixels configured to generate a first signal corresponding to an amount of received light, and output the first signal; an AD converter configured to convert the first signal into a digital second signal by performing AD conversion processing for the first signal, and output the second signal; a transmitter/receiver configured to transmit and receive, in a time division manner, transmission data including at least the second signal in a first period, and reception data input from an outside in a second period; and a first generator configured to generate a first clock signal synchronized with the clock edge included in the reception data. The transmitter/receiver is configured to switch between the first period and the second period every horizontal line in the pixel unit, and transmit and receive the transmission data and the reception data in a time division manner.
