DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of an endoscope system according to the first embodiment of the present invention.
[0007]
In the endoscope system 1 of FIG. 1, an electronic endoscope 2 including an image pickup device such as a CCD (not shown) at the distal end in order to obtain an endoscopic image of a region to be examined is an electronic endoscope 2 of this type. It is connected to a video processor 3 that performs drive control of the image sensor, processing of an output signal from the image sensor, recognition of code information described later, and the like, and displays an image captured by the electronic endoscope 2 on the video processor 3. An observation monitor 4 for observation and a video tape recorder (VTR) 5 for recording the observed image and reproducing and recording the recorded image are connected. This VTR 5 not only records and reproduces endoscopic images, but is not shown in the figure, but at least an explanation image in which the contents of the instruction for handling of the video processor are recorded, and an arbitrary number indicating the beginning and end of the explanation, etc. A videotape on which characters or index information is recorded is played back. In an electronic endoscope, an endoscopic image uses an NTSC standard signal in Japan, the United States, etc., and the NTSC standard has a video signal portion and a sync signal portion. Y / C signal that separates and transmits the color signal, composite signal that combines and mixes the luminance signal and color signal, and transmits the signal separately into the three primary colors red, green, and blue There are RGB signals. In either case, a vertical blanking period (also referred to as a vertical blanking period) for resetting the vertical deflection of the observation monitor is provided. Nowadays, as disclosed in the November 85 issue of Television Technology of Electronic Technology Publisher, using the part without video signal of this vertical blanking period, character multiplex broadcasting, video tape index information, etc. Character data is superimposed on the original video signal. Accordingly, the character or index information indicating the beginning and end of the description can be realized by using such a technique.
[0008]
The video processor 3 selectively switches between an image signal processing unit 6 that processes an output signal from the image sensor of the electronic endoscope 2, and an endoscopic image from the image signal processing unit 6 and a reproduced image from the VTR 5. Output image switching unit 7, keyboard unit 8 for inputting patient data and the like, operation panel 9 for operation input for performing various settings of the video processor 3 itself, CPU 10 for performing various controls, operation When a video tape on which an arbitrary number of characters or index information indicating the beginning and end of the explanation is recorded and at least the explanation image recording the content of the handling explanation of the video processor is reproduced, the image signal is superimposed and recorded. And a code recognition unit 11 for detecting and recognizing a predetermined specific code signal.
[0009]
Next, the operation of this embodiment will be described.
At the time when the endoscope system 1 is shipped from the factory, the image switching unit 7 switches the image output to the observation monitor 4 in advance so as to select the reproduced image from the VTR 5 instead of the image from the electronic endoscope 2. Is set. At this stage, even if the user inputs an image switching instruction from the operation panel 9, it is programmed in the CPU 10 so that it cannot be switched to output an image from the electronic endoscope 2, and the switching operation is locked. . The user reproduces the upper video tape on which the handling instruction image is recorded, and the video processor is explained using the observation monitor 4. The explanation start code information, which is a start signal indicating the start of the explanation of the explanation of the contents of the explanation of the video processor preliminarily superimposed within the vertical blanking period of the explanation image, is stored in the VTR 5 as the video tape is reproduced. The signal is sent to the CPU 10 after being separated and recognized from the video signal by the code recognition unit 11, and the CPU 10 stores the time information when the code information is transmitted to the CPU 10 in addition to the code information itself. It is like that. Although the detailed detection and recognition method by the code recognition unit 11 is not particularly described, it can be realized by an equivalent to a character broadcast decoder circuit used in general character multiplex broadcasting. Similarly to the explanation start code information, explanation end code information which is an end signal indicating the end of the explanation of the explanation image of the contents of the handling explanation of the video processor preliminarily superimposed within the vertical blanking period of the explanation image In addition, the signal is sent to the CPU 10 after being separated and recognized from the video signal by the code recognition unit 11, and the CPU 10 stores the time information when the code information is transmitted to the CPU 10 in addition to the code information itself. It has become.

The number of records and the recording location can be arbitrarily combined. Further, the recording medium is not limited to the video tape, and any means capable of outputting a video signal, such as a DVD or a laser disk, can be the configuration of the present application. Furthermore, in the present embodiment, an example in which the vertical blanking period of an analog television signal is used in consideration of the currently popular media has been shown, but in the future digital video signal transmission will be performed. Even when the media has become digital, it is a feature of the digital system that can handle a large amount of information compared to the analog system, so a very small amount of data such as a confirmation code can be converted into the original image data. Mixing and recording can be easily handled.
[0013]
In the first embodiment, the object to be locked is the switching operation of the image switching unit 7. However, the present invention is not limited to this, and the illumination light is emitted from a light source device (not shown) connected to the video processor 3. You may lock so that operation | movement may be prohibited, and you may lock so that input operation from the keyboard part 8 provided in the video processor 3 or the operation panel 9 may not be accepted at all.

[0023]
In the case of imaging a subject with an electronic endoscope, conventionally, in order to obtain a good color image, after white balance adjustment is performed with a white balance adjustment tool as disclosed in Japanese Patent Laid-Open No. 4-69615, the electronic internal I was using an endoscope. In order to confirm and adjust the image quality of the electronic endoscope to the minimum, it is sufficient to pay attention to white balance. However, in order to perform fine adjustment and confirmation, attention should be paid to other image quality factors such as black balance and resolution. There is a need. However, depending on the image quality to be confirmed, it is necessary to prepare multiple chart means such as a white balance cap, and it is troublesome to store the chart, and what chart should be prepared for the user to measure what image quality It is necessary to completely grasp the image, and it is necessary to image the chart straight from the front, and it is not easy to realize these completely. This configuration example can solve these problems.
[0024]
In FIG. 4, the electronic endoscope 2 includes a distal end bending portion 51, an angle wire 52 for bending the distal end bending portion 51, and an angle knob 53 for operating the angle wire 52 to perform a bending operation. Is provided. The angle wire 52 has an endless belt shape, and is wound around a rotating drum 54 that is rotatable substantially integrally with the angle knob 53 in a sub-operation portion (not shown) of the endoscope. The end portion is connected to the tip configuration portion of the electronic endoscope. A rotation angle detection means 55 for detecting the rotation angle of the rotary drum 54 is provided in the sub operation unit. Specifically, the rotation angle detection means can be realized by a known magnetic sensor, rotary encoder, or the like. The bending amount display means 56 calculates and displays the bending amount of the endoscope tip based on the rotation angle of the rotating drum detected by the rotation angle detection means 55. The chart means 60 is capable of inserting a distal end bending portion of an endoscope, and has, for example, a white balance chart 60a, a resolution chart 60b, and a black balance chart 60c on its inner wall surface. Assuming that the resolution chart 60b can be viewed directly from the front of the endoscope, the white balance chart 60a and the black balance chart 60c are arranged at equal angular intervals, for example, 45 ° intervals in the vertical direction from the reference. Therefore, the desired white balance chart 60a and black balance chart 60c can be directly viewed from the front if the distal end bending portion of the endoscope is bent 45 degrees in the vertical direction. A chart indicating means 57 is connected to the bending amount display means 56. When a chart instruction is input from the chart instruction means 57, a numerical value such as a bending amount, ie, a target bending angle, for bending the endoscope distal end bending portion in order to accurately directly view the selected chart from the front, is displayed. 56. At this time, the actual bending amount of the endoscope distal bending portion is also displayed on the bending amount display means 56 at the same time.

According to this configuration example, the user simply inputs and inputs information related to the image quality to be confirmed or the type of chart to be selected, and the amount of bending, which is the position information of the desired chart, is displayed and matches the displayed numerical value. It is only necessary to operate the angle knob 53. When both numerical values coincide with each other, it is possible to secure a state in which the endoscope directly views the chart directly from the front, and it is possible to reliably capture the chart with a simple operation.
[0027]
In this configuration example, the user operates the angle knob based on the display so that the chart can be directly viewed directly from the front. However, the rotary drum 54 can be rotated by a motor, and the rotation angle of the motor is set to the target angle. If the feedback control is performed so as to match, the entire operation can be automated, which is more convenient.
[0028]
