    摘要: A medical image processing device includes a processor configured to: obtain image data; generate, based on the obtained image data, a captured image including color component signals including a red component signal representing a red component, a green component signal representing a green component, and a blue component signal representing a blue component; calculate an intensity ratio between a fluorescent component signal and a reflected light component signal in a pixel of the captured image; determine, based on the calculated intensity ratio in the pixel of the captured image, a fluorescence region and a background region in the captured image; and generate a fluorescence image by performing, based on a result of the determination, image processing with parameters different from each other for color component signals in pixels positioned in the fluorescence region and color component signals in pixels positioned in the background region.

    摘要: An imaging device includes a voltage generation circuit and an output circuit. The voltage generation circuit includes a first capacitance element including a fifth terminal. The voltage generation circuit is configured to provide the fifth terminal with a first voltage in accordance with a power source voltage so as to store an electric charge in the first capacitance element. The voltage generation circuit is configured to increase a voltage of the fifth terminal by a second voltage in accordance with the power source voltage so as to generate a control voltage having a greater absolute value than an absolute value of the power source voltage. The output circuit is configured to output the control voltage to at least one of a gate terminal of a reset transistor of a pixel and a gate terminal of a transfer transistor of the pixel.

    摘要: A light source device includes a semiconductor light source that radiates light at a light quantity according to an applied current, a circuit that determines a current instruction value based on control information, first and second drive units, each of the units that is connected to the semiconductor light source and the circuit, and is capable of outputting, to the semiconductor light source, a current having magnitude corresponding to the current instruction value. The control information is set based on brightness of an image captured by an imaging element. When one of the first and second drive units is switched to the other, the circuit causes the other to start the current output after an elapse of a predetermined stop time period having a length at a predetermined ratio or less to a frame rate on the imaging element since a stop of the current output from the one.
