  The first to third cables C1 to C3 may be independent cables or may be accommodated in one cable. In the present embodiment, the cables are independent from each other, and in particular, the second cable C2 will be described as an RS-232C cable.

  A light guide (not shown) made of a large number of optical fibers for guiding illumination light is inserted into the electronic scope 10, and the light guide extends to the distal end of the insertion portion 12 of the electronic scope 10.

  The first CPU 22 of the image processor 20 is, for example, a microprocessor that controls the entire electronic endoscope system 1 and the video printer 40. The light source unit 23 includes a light source such as a xenon lamp that emits white light for illumination, and a light source driving circuit for driving and driving the light source. The diaphragm mechanism 24 includes a diaphragm for adjusting the amount of light emitted from the light source unit 23 and a diaphragm driving circuit that drives the diaphragm. The stop is disposed on the optical path of the emitted light from the light source of the light source unit 23.

  When the connection unit 13 of the electronic scope 10 is connected to the image processor 20, the light guide is optically connected to the light source of the light source unit 23 via the aperture mechanism 24. When the light source lighting operation is performed by the user, a lighting driving signal is output from the light source driving circuit of the light source unit 23 to the light source based on the control signal from the first CPU 22, and white light is emitted from the light source. A driving signal is output from the aperture driving circuit of the aperture mechanism 24 to the aperture based on the control signal from the first CPU 22. As a result, the amount of white light emitted from the light source unit 23 is adjusted by the diaphragm mechanism 24 and enters the incident end of the light guide. The incident white light is guided to the tip of the insertion portion 12 of the electronic scope 10 by the light guide, and is irradiated to the object to be observed as illumination light through the light distribution optical system.

  Reflected light from the object to be observed enters the image sensor 14 through an objective optical system (not shown), and an optical image of the object to be observed is formed on the incident surface of the image sensor 14. In a state where the connection unit 13 is connected to the image processor 20, an image sensor driving circuit (not shown) of the connection unit 13 is connected to the first CPU 22. When an image sensor driving signal is output from the image sensor driving circuit based on a control signal from the first CPU 22, the image sensor 14 photoelectrically converts an incident optical image of the observed object, and an analog image signal based on the optical image. Is output.

  The analog image signal output from the image sensor 14 is subjected to image signal processing of the previous stage such as A / D conversion in the signal processing circuit 19 of the connection unit 13 and input to the signal processing unit 25 of the image processor 20. The image processing unit 25 performs predetermined image signal processing such as amplification processing, gamma correction, and contour enhancement on the digital image signal, and stores it as image data in an image memory (not shown) provided in the signal processing unit 25. The image data in the image memory is read out in a timely manner, subjected to video signal processing conforming to the specifications of a predetermined video signal, and output to the main monitor 30 and the video printer 40. As a result, the object image is displayed on the main monitor 30 and the object image is printed out by the video printer 40.

Yes. In particular, in the present embodiment, icons and programs for operating the video printer 40 are stored. The second CPU 26 is connected to the image memory of the signal processing unit 25. The image data in the image memory, the image data stored in the auxiliary recording device, and the video signal output from the video printer 40 are read out and output to the touch panel 21 under the control of the second CPU 26. Accordingly, the object image to be observed can be displayed on the touch panel 21, and in particular, an image printed out by the video printer 40 and output from the video printer 40 can be displayed.

  As described above, the touch panel 21 includes an image of the object to be observed (memory image) stored in the image memory or the like of the signal processing unit 25 or a video (input image) output from the video printer 40, and the auxiliary recording device 27. Stored icons and the like can be displayed. These display modes on the touch panel 21 are controlled by the second CPU 26 as described later.

  In the present embodiment, the image data of the object to be observed can be displayed in synchronization with the main monitor 30 and the touch panel 21. A command signal for instructing image display from the first CPU 22 to the second CPU 26 is output in synchronization with the image data of the object to be observed being sent from the image memory of the signal processing unit 25 to the main monitor 30 under the control of the first CPU 22. The When this command signal is input, the second CPU 26 reads the image data from the image memory and outputs it to the touch panel 21. As a result, the observed object image is displayed on the main monitor 30 and the touch panel 21 in synchronization.

  Image data in the image memory such as a temporarily stored still image is read based on the control of the second CPU 26 and recorded in the auxiliary recording device 27 or the external storage device 60.
