Abstract: 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.

In a second step, a place adjacent to a side around the reference field of view is numbered, then the measurement range is automatically moved to sequentially execute measurement at that position, presence of shape data is checked, measurement results is stored, and, presence of shape data at the numbered position is recorded on a memory device. In a third step, field of view with shape data found therein as a next reference field of view is employed, a place adjacent to a side around the reference field of view is numbered, then the measurement range is automatically moved to sequentially execute measurement at that position other than a position at which measurement has already been made or no shape data is found.
