Abstract

In an electronic endoscope system, an endoscopically-processed endoscopic image such as a color-enhanced endoscopic image is photographed with a simple operation. The electronic endoscope system comprises: an endoscopic image producing unit for producing an endoscopic image signal of an object under medical examination as original endoscopic image data; an endoscopic image processing unit for processing the original endoscopic image data so as to obtain endoscopically-processed image data; a photographing unit for selectively photographing the original endoscopic image data and the endoscopically-processed image data; an image confirming unit for selectively receiving the original endoscopic image data and the endoscopically-processed image data so as to confirm a content of the received image data; and, an image data transferring unit for transferring the original endoscopic image data and the endoscopically-processed image data simultaneously to at least both the photographing unit and image confirming unit in response to an instruction signal. Then, the transferred image data is photographed by the photographing means while the content thereof is confirmed by the image confirming unit.

Claims

1. An electronic endoscope system comprising:

endoscopic image producing means for producing an endoscopic image signal of an object under medical examination as original endoscopic image data of said object;

endoscopic image processing means for processing said original endoscopic image data so as to obtain endoscopically-processed image data;

photographic means for successively photographing said original endoscopic image data and said endoscopically-processed image data;

image confirming means for successively receiving said original endoscopic image data and said endoscopically-processed image data so as to confirm the contents of said original and endoscopically-processed image data; and

,

image data transferring means for simultaneously transferring said original endoscopic image data and said endoscopically-processed image data to at least both said photographing means and image confirming means in response to an instruction signal, whereby said original and endoscopically-processed image data simultaneously transferred to said image data confirming means are successively photographed by said photographing means while the contents thereof are confirmed by the image confirming means.

2. An electronic endoscope system as claimed in claim 1, wherein said image producing means includes:

a solid-state image sensor positioned at one distal end of a scope, for photoelectric-converting an image of said object into said endoscopic image signal thereof;

a camera control unit for converting said endoscopic image signal into an original endoscopic image signal; and

,

an analog-to-digital (A/D) converter for A/D-converting said original endoscopic image signal into the original endoscopic image data.

3. An electronic endoscope system as claimed in claim 1, wherein said endoscopic image processing means processes said original endoscopic image data so as to obtain hemoglobin-concentration-distributed image data, as the endoscopically-processed image data.

4. An electronic endoscopic system as claimed in claim 1, wherein said endoscopic image processing means processes original endoscopic image data so as to obtain color-enhanced image data, as the endoscopically-processed image data.

5. An electronic endoscope system as claimed in claim 1, wherein said endoscopic image processing means processes original endoscopic image data so as to obtain structure-enhanced image data, as the endoscopically-processed image data.

6. An electronic endoscope system as claimed in claim 1, wherein said endoscopic image processing means processes said original endoscopic image data so as to obtain infrared image data, as the endoscopically-processed image data.

7. An electronic endoscope system as claimed in claim 1, wherein said image confirming means includes:

a first television monitor for successively displaying said original endoscopic image of said object under medical examination in a real time mode and said endoscopically-processed endoscopic image thereof in a frozen image mode; and

,

a second television monitor for displaying said endoscopically processed endoscopic image in a real time mode.

8. An electronic endoscope system as claimed in claim 1, wherein said image confirming means includes:

a monitor successively capable of displaying in a dual-display mode both an original endoscopic image of said object under medical examination in a real time mode and an endoscopically-processed endoscopic image thereof in a real time mode; and

a video printer for printing out said original endoscopic image and endoscopically-processed endoscopic image.

9. An electronic endoscope system as claimed in claim 1, wherein said image data transferring means is a selector having first and second switchable contacts.

10. An electronic endoscope system as claimed in claim 1, wherein a first image memory is employed to store said original endoscopic image data derived from said endoscopic image producing means;

a second image memory is employed to store said endoscopically-processed endoscopic image data derived from said endoscopic image processing means; and

a memory controller is employed as said image data transferring means so as to control both said first and second image memories.

11. An electronic endoscope system as claimed in claim 10, wherein said memory controller 15 includes:

a switch register for receiving said instruction signal to output a switch manipulation signal;

a processing unit for processing said switch manipulation signal based upon a system control program to produce a register control signal; and

,

a control register for selectively producing a first memory control signal and a second control signal in response to said register control signal.

12. An electronic endoscope system as claimed in claim 1, wherein said instruction signal is produced from a selected one of a copy switch and a foot switch.
