PROBLEM TO BE SOLVED: To provide an endoscope device for enabling an imaging part included in an insertion part tip of an endoscope to acquire an observation image having high quality and a high frame rate, and its operation method.SOLUTION: The endoscope device includes an endoscope for irradiating illumination light from an insertion part tip, and outputting a frame image signal obtained by performing imaging by an imaging part included in the insertion part tip, and a processor device having an image processing part connected to the endoscope. An operation for irradiating illumination light to a former half period obtained by dividing a frame period of the frame image signal into two and performing lights-out during the latter half period of the frame period is repeated in each frame period, and the former half period of the frame period is read during an exposure period and a signal of accumulated electric charge after the exposure is read within the latter half period to be outputted to a buffer memory mounted in the endoscope. Image information of the frame image signal is read from the buffer memory within the frame period and transferred to the image processing part.SELECTED DRAWING: Figure 5 |
