Abstract: There are provided an endoscope system, a processor apparatus for an endoscope system, and a method for operating an endoscope system. In a special observation mode, first illumination light and second illumination light having a spectral property different from a spectral property of the first illumination light and including different-absorption-wavelength light that has different absorption coefficients for oxygenated hemoglobin and reduced hemoglobin are alternately emitted to a test body while a turn-off period is interposed. A first image capture signal is read from the image sensor during the turn-off period after emission of the first illumination light, and a second image capture signal is read from the image sensor during the turn-off period after emission of the second illumination light. Here, a second read time taken to read the second image capture signal is made shorter than a first read time taken to read the first image capture signal.

Abstract: Illumination light is continuously emitted and auxiliary measurement light is emitted in the form of a pulse at a specific frame interval. A subject illuminated with illumination light is imaged to obtain a first taken image. A subject illuminated with illumination light and auxiliary measurement light is imaged to obtain a second taken image. A specific image where a measurement marker obtained from the second taken image is displayed in the first taken image is displayed on a display unit.

Abstract: The endoscope includes an imaging device that is provided in a tip portion of an insertion part capable of being inserted into a body cavity. The imaging device includes an image sensor that photoelectrically converts imaging light incident on an image receiving surface thereof through an imaging lens provided in a lens barrel, and a circuit substrate including a connecting surface facing a terminal face that is a surface opposite to the image receiving surface of the image sensor. A plurality of terminals are uniformly arranged longitudinally and laterally in a two-dimensional matrix form on the terminal face of the image sensor, and the connecting surface of the circuit substrate and the terminal face of the image sensor are connected to each other through the plurality of terminals. The total area of the plurality of terminals on the terminal face occupies 10% or more of the area of an imaging area of the image receiving surface.
