合には見に＜＜、誤操作、誤診断の原因となる。Generally, when observing and treating the affected area without observing the image displayed on the TV monitor by attaching a camera to the eyepiece of the endoscope, the examiner holds the operating section of the endoscope. If you are operating the endoscope while looking at the image on the monitor TV, or because the monitor TV is placed far away from the endoscope, if the image size displayed on the monitor TV is too small, you may not be able to see it. <This may cause incorrect operation or misdiagnosis.

The goal is to determine the image size information of the endoscope and enlarge or reduce it so that a fixed image of the chair is displayed on the monitor TV, making the image easier to view, easier to use, and easier to diagnose. It is an object of the present invention to provide an endoscope device that can be easily used.

映し１１１される。This camera 17 is connected to a camera control unit, and the video signal from the solid-state image sensor 16 is transmitted to one camera control unit. Camera controller i above
- The roll unit 18 is provided with an image size determination circuit 18a that counts the size L of the circular image captured by the solid-state image sensor 16 using a scanning method. In this image size determination circuit]-8a, the image captured by the solid-state image sensor 16 is located at the center of the solid-state image sensor 16, and the 1/2 point in the vertical direction is the maximum image size between A-8. Under this condition, during this period, the timing circuit 2o opens the gate 1.21 and inputs the image signal from the solid-state image sensor 15 to the waveform shaping circuit 22 having a threshold level. The waveform shaping circuit 22 distinguishes the threshold value between A and B, and inputs a pulse signal that is equal to or higher than a set level to the counter 23. This counter 23 is connected to a clock pulse generator 24
The comparator 25 then compares the image size L with a reference value stored in advance in the 2-dimensional circuit 26 to determine the image size L. That is, when the image size L is smaller than the reference value, an enlarged signal corresponding to the difference is inputted to the image processing circuit 27, and when it is larger, a reduced signal is inputted to the image processing circuit 27. This image processing circuit 27 inputs an image signal from the solid-state image sensor 16 via a delay circuit 28, corrects the image signal based on the enlarged signal [7] or the reduced signal, and displays it on a single monitor television. input. [Across,
[Monitor TV] 9 is always displayed at a constant size (reference value) 111.

修正することができる。As explained above, this invention provides a discrimination circuit that discriminates image size information of an endoscope, and enlarges or reduces the image size based on this discrimination signal to display an image of a fixed size on a monitor television. I can do it,
Images are easy to see even when operating and diagnosing an endoscope without observing a TV monitor screen located far away.
This has the effect of improving operability and facilitating diagnosis. Furthermore, image distortions that differ from endoscope to endoscope can also be corrected.
