In an endoscope device, a control unit brings an imaging device into an operation in a first read-out mode. In the first read-out mode, the imaging device reads out pixel signals from a plurality of pixels in a first time. After an instruction for the measurement of a subject is generated, the control unit brings the imaging device into an operation in a second read-out mode. In the second read-out mode, the imaging device reads out the pixel signals from the plurality of pixels in a second time. The second time is shorter than the first time. The control unit causes an imaging condition switching unit to switch imaging conditions on the basis of an operation of the imaging device in the second read-out mode.
