DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scope inserted into an organ of a human body or the like and a T for displaying a captured image.
The present invention relates to an electronic endoscope apparatus including a processor to which a monitor for V is connected, and particularly to an electronic endoscope system including a plurality of processors.

On the light receiving surface of the image sensor, an image signal corresponding to the subject image is generated by photoelectric conversion and sent to the processor. The image signal sent to the processor is converted into a video signal (video signal) such as an NTSC signal and output to a display device such as a monitor. This allows an operator such as a doctor to observe the captured image on the monitor. The processor has
In addition to the monitor, various devices such as an image recording device for recording the captured image on a film or a magnetic storage medium, a printer for printing the captured image, and a keyboard for inputting patient information to the monitor are appropriately provided. It is connected.

[0003] Since the scope (type of diameter, etc.) differs depending on the site to be observed, when observing a plurality of sites such as the bronchus and the large intestine at the same time, it is necessary to replace the scope each time. In addition, when using an electronic endoscope device in a group examination, the same scope cannot be used for a plurality of persons, so it is necessary to replace the scope each time one person's diagnosis is completed. Therefore, conventionally, an electronic endoscope system including a plurality of processors has been applied, and a scope to be used is appropriately connected to the processors to make a diagnosis. Thereby, various parts can be observed and many patients can be diagnosed.

[0004]

However, when a plurality of processors are used, the number of peripheral devices such as monitors, image recording devices, and keyboards connected to the processors increases accordingly. Therefore, a large amount of equipment is required for performing a diagnosis or the like, and the cost is high economically. In addition, a large space is required for setting the system, and the troublesome setting reduces the diagnostic efficiency. Furthermore, since the method of operating a keyboard for executing processes such as displaying a list of patient names and enhancing the contour of a subject image differs for each processor, the operator must master the operation methods of a plurality of keyboards. This confuses the operator and reduces the work efficiency.

Accordingly, the present invention relates to a method of operating peripheral devices such as a keyboard for operating a processor while improving space efficiency and work efficiency, and provides an electronic endoscope system capable of performing operations appropriately and efficiently. The purpose is to do.

[0043]

[Table 2]

Normally, the processor system differs depending on the imaging method, so that the keyboard input operation (operating function keys) at the time of performing the processor processing also differs depending on the imaging method. For example, when the function key F2 is operated, the first processor 40 of the frame sequential system, which is the “apparatus 1”, executes a list display process of doctor names. On the other hand, in the simultaneous single-plate type second processor 60 of the “device 5”, when the function key F2 is operated, the time displayed on the monitor 150 is reset. Further, the processing for the operation of the function keys F1 to F4 is different depending on the same imaging method. For example, when the function key F4 is operated, the first processor of the “device 1” executes a time reset process, and the first processor 40 of the “device 2” executes a list display process of doctor names.

On the other hand, the correspondence between the function keys F1 to F4 on the keyboard 170 and the processor processing is determined to be the same as that of the first processor 40 of the “device 1”. Therefore, when a processor other than the “device 1” is selected, a processor process different from a desired process may be executed. Therefore, in the present embodiment, regardless of the selected processor, when any one of the function keys F1 to F4 is operated, the keyboard 170 is operated so that a processor process corresponding to the operated key can be executed. Performs conversion processing of the transmitted signal.

The processor switching signal SSWS sent to 0 becomes a high-level signal “1” when the first processor 40 is selected, and becomes a low-level signal “0” when the second processor 60 is selected. . On the other hand, operation signals F1 to F4 are output from the keyboard 170 by operating the function keys F1 to F4, respectively.

For example, the first processor 40 of “device 1” and the second processor 60 of “device 5” are connected to the switching device 200, and the first processor 40 of “device 1” is connected.
Is selected by the switching device 200 (when the video signal output from the first processor is sent to the monitor 150 or the like), the levels of the signals input to the inputs in0 to in4 are sequentially set to “ 1 "," 1 ",

[0050]

[Table 3]

As described above, in this embodiment, the input operation (key operation) for executing the processor process matches the input operation on the first processor 40 which is the “device 1”, and other input operations are performed. When the type of processor is selected by the switching device 200, the operation signal is converted.
For example, when the processor of “device 5” is selected by the switching device 200, when the function key F2 of the keyboard 170 is operated, the operation signal F2 is sent to the keyboard information memory 226. As shown in Table 2,
The function key F2 is a key for executing a doctor list display process for the first processor 40 of the “device 1”, but the function key F2 executes a time reset process for the second processor 60 of the “device 5”. Is the key to Therefore, the input operation signal F2 that is input is a function key F that is a key for displaying a doctor list for the second processor 60 of the “device 5”.
3 is converted into an operation signal F3 corresponding to the operation signal F3. The correspondence between the operation signals F1 to F4 from the keyboard 170 shown in Table 3 and the output operation signals F1 to F4 is predetermined for each processor, and is stored in the keyboard information memory 226 in advance.

The converted operation signals F1 to F4 are sent to the first processor 40 or the second processor 60 via the keyboard buffer circuit 222. When the function key F3 of the keyboard 170 is operated while the second processor 60 of the “device 5” is selected,
No processing is executed because the screen resetting processing is impossible.

As shown in Table 5, the key operation processing name memory 350 has "patient list", "doctor list", "screen reset", "clock reset", and "character list" which are character information to be displayed on the LCDs 380 to 383. The display data of “none” for the undefined function key is stored, and the data of character information corresponding to the keyboard indicator signal KISS is read out by the LCD driver 340. In FIG. 11, the character information for “device 1” is displayed. However, when the second processor 60 that is “device 5” is selected by the switching device 200, the LCDs 380 to 380 are displayed.
At 383, character information is displayed in the order of "patient list", "clock reset", "doctor list", and "none".
