The first selector outputs one of the observation image data and the synthesized image data to a first display device as first selected data. The second selector outputs one of the first selected data and the recorded image data to a second display device as second selected data. The selector interlock controller interlocks and controls the first selector 122 and the second selector 124.

Abstract: A video processor for an endoscope includes an image memory, an image processing unit, a display control unit and a recording unit. The image memory stores, as a sample image, an endoscope image which a user previously acquired. The image processing unit performs the image processing for changing an image quality of the sample image in accordance with a selection value selected by a user and produces a processed image. The display control unit causes a display unit to display the processed image. The recording unit records, as a setting value, a value relating to the selection value determined by the user. The image processing unit performs the image processing, based on the setting value, for the endoscope image.
