れる画像サイズが大小すべて異なる。There are many types of endoscopes depending on the purpose of use, such as gastrophy scopes, esophageal fiberscopes, and colon fiberscopes. These endoscopes all have different observation optical systems depending on the diameter of their insertion portions, so the sizes of the images taken by the cameras attached to the eyepieces are all different. Therefore, if the information captured by the camera is directly transmitted to the monitor television via the camera control unit, the size of the image displayed on the screen of the monitor television will be different.

The endoscope is operated while viewing images on a TV, but since the monitor TV is installed at a distance from the endoscope,
If the image size displayed on the monitor TV is small, it may cause errors in viewing, incorrect operations, and misdiagnosis.

になっている。The present invention will be described below based on embodiments shown in the drawings. 1 and 2 show a first embodiment of the present invention, in which 1 is an endoscope. Operation section 2 of this endoscope 1
is provided with an eyepiece 3, and a camera 4 is removably attached to the eyepiece 3. The camera mounting surface 5 of the eyepiece section 3 is provided with a format display section 6 for displaying the format of the wedding invitation@1, and the joint surface 7 of the camera 4 is provided with a format reading section 8 corresponding to the format display section 6. is provided. That is, the type display section 6 is located on the camera mounting surface 5.
It is formed from several recesses 9 arranged along the outer periphery of the recess 9 and conductive pieces 10 selectively buried in these recesses 9, and the arrangement of these conductive pieces 10 and The type of endoscope 1 is displayed by the number of pieces. The format reading section 8 is formed by a plurality of pairs of terminal pins 11h and 11b protruding from each other corresponding to the intervals between the recesses 9, and these terminal pins 11a and 11b connect the camera 4 to the eyepiece. 3, it comes into contact with the conductive piece 10 and is selectively short-circuited.

ズを解消できる。Therefore, by embedding conductive pieces 10 in the four parts 9 arranged on the camera mounting surface 5 of the endoscope 1 depending on the type of the endoscope 1, the arrangement and number of conductive pieces 10 can be changed. By simply attaching the camera 4 to the part 3, the terminals 11m and 11b are short-circuited or insulated, and this combination allows the endoscope discrimination circuit 12 to discriminate the type of endoscope 1. Therefore, the discrimination signal from the endoscope discrimination circuit 12 is enlarged or reduced by the image processing within the camera control unit 14 and displayed on the monitor television 15 at a constant image size, so that it can be used even if the examiner is far away from the monitor television 15. The t+Iii WJ can be easily observed even when the endoscope 1 is used, and the conventional image size that varies depending on the type of endoscope 1 can be resolved.

It is a solid-state image sensor such as D. This camera 17 is connected to a monitor television 19 via a camera control unit 18 and transmits a video signal from the solid-state image sensor 16 to the monitor television 19 via the camera control unit 18. The camera control unit 18 is provided with an image size determination circuit 18h that counts the size L of the circular image captured by the solid-state image sensor 16 using a scanning method. This image size discrimination circuit 1
8&, the image captured by the solid-state image sensor 16 is located at the center of the solid-state image sensor 16, and the point A in the vertical direction is A-B.
On the condition that the maximum image size L is between 1 and 2, the dart 21 is opened by the timing circuit 20 during this period, and the image signal from the solid-state image sensor 16 is input to the waveform shaping circuit 22 having a threshold level. The waveform shaping circuit 22 distinguishes the threshold value between A and B, and if the iE is equal to or higher than the set level,
The pulse signal is input to the counter 23. This counter 23
is counted in response to a clock pulse from a clock pulse generator 24, and then compared with a base value stored in advance in a storage circuit 26 in a comparator 25 to determine the image size L. That is, if the image size L is smaller than the reference value, a 1-enlargement signal corresponding to the difference is input to the image processing circuit 27, and in the case of a dog, a reduction signal is input to the image processing circuit 27. This image processing circuit 27 receives an image signal from the solid-state image sensor 16 via a delay circuit 28, corrects this image signal based on the enlarged signal or reduced signal, and outputs the image signal to the monitor television 1.
Enter 9. Therefore, the image on the monitor television 19 is always displayed at a constant size (reference value).

By enlarging or reducing the image size, the image can be displayed on a monitor TV as a fixed-sized image, and the image can also be displayed when operating the endoscope or diagnosing while observing the screen of a monitor TV installed at a remote location. This has the effect of making the image easier to see, improving operability, and making diagnosis easier. Furthermore, image distortions that differ depending on the endoscope can also be corrected.
