BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic endoscope apparatus for inspecting, treating, etc., an organ such as a stomach, and more particularly to a plurality of electronic endoscopes (hereinafter referred to as a videoscope) for a processor. ) Is connectable, the present invention relates to a data setting process for setting data related to signal processing according to the characteristics of the videoscope to be connected.

[0002]

2. Description of the Related Art In a conventional electronic endoscope apparatus, a nonvolatile memory in a videoscope is provided with data relating to signal processing according to the characteristics of the videoscope (white balance R, B gain values, CCD gain values). Is stored in advance, and when the videoscope is connected to the processor of the electronic endoscope apparatus, the data in the memory is read out to the processor. In the processor, image signal processing is performed based on the setting based on the read data, and the video signal is output to the monitor. As for the processor, a plurality of videoscopes of different models can be connected to each other, and one videoscope corresponding to the observation site is attached.

The signal processing characteristics may differ depending on the individual processor. If the data read from the connected videoscope is set as it is, white balance may not be properly performed. Therefore, once the data related to signal processing is set,
Data adjustment is performed by the operator according to the connected processor.

[0004]

When a large number of video scopes can be connected to one processor, it is necessary to connect the video scopes to the processors one by one to adjust data relating to image signal processing. , Spends a lot of time on the adjustment work. Further, when a plurality of processors of different models are prepared, it is necessary to adjust the data for each processor, and the work time becomes enormous.

Therefore, the present invention relates to a processor to which a plurality of videoscopes can be connected, and an object thereof is to obtain a processor of an electronic endoscope apparatus capable of efficiently and appropriately adjusting data.

[0006]

A processor of an electronic endoscope apparatus according to the present invention is a processor of an electronic endoscope apparatus that can be connected to a plurality of videoscopes. Then, signal processing is executed and a video signal is output to a monitor or the like. The processor is
A set of data defined for each of the plurality of video scopes, and a memory capable of storing a plurality of sets of scope data relating to signal processing is provided. The scope data set includes, for example, R and B in white balance adjustment.
It includes gain data, delay time data, CCD gain data, and the like. Values for these sets of scope data are set according to the characteristics of the video scope,
For example, a scope memory that stores a set of scope data is provided in the video scope. in this case,
When the video scope is connected to the processor, a set of scope data is read from the scope memory and stored in the memory inside the processor. In the signal processing circuit in the processor, signal processing is performed on the image signal sent from the videoscope based on the set of scope data.

When a specific video scope is connected to a processor, a predetermined data is used to correct specific scope data (R gain data etc.) in the set of scope data according to the connected video scope. The adjustment operation is performed by the operator. The processor includes adjusting scope data setting means, and the adjusting scope data setting means performs a predetermined data adjusting operation in a set of scope data corresponding to a specific video scope according to a predetermined data adjusting operation for a specific video scope. Set adjustment scope data that is a modification of the corresponding specific scope data. For example, in order to correct (adjust) the value of the R gain data preset for the connected video scope to 1.2 times, if the operator performs a predetermined input operation on the keyboard, etc., the adjustment scope data The setting means sets the corrected data as adjustment scope data. The adjustment scope data may be stored in the memory of the processor.

When a predetermined video scope is connected, the processor of the present invention sets the automatic adjustment target scope data corresponding to the specific scope data in the set of scope data corresponding to the predetermined video scope to the specific scope data. And automatic adjustment scope data setting means for converting and setting the automatic adjustment scope data calculated based on the values of the adjustment scope data. Therefore,
When a predetermined video scope is connected, the scope data (R gain data, etc.) of the predetermined video scope is automatically generated based on the values of the scope data and the adjustment scope data relating to the previously connected specific video scope. Adjusted. The signal processing circuit of the processor performs signal processing on the image signal based on the automatically adjusted scope data. With such automatic adjustment, if a predetermined videoscope is connected to the processor, data suitable for the processor can be efficiently and appropriately set.
Note that the present invention is effective when a plurality of videoscopes of different models (types) are connected depending on the observation target such as the stomach and large intestine, but is also effective when a plurality of videoscopes of the same model are connected. Is.

It is possible to calculate the automatic adjustment scope data using various functions. However, since the automatic adjustment standard initial data having an appropriate value is calculated by a simple formula, It is desirable to calculate the automatic adjustment scope data based on the ratio with the adjustment scope data. In this case, the automatic adjustment scope data setting means calculates and sets the automatic adjustment scope data based on a function having a ratio of a specific scope data and the adjustment scope data (hereinafter referred to as a scope data ratio) as a proportional constant. .
For example, when the ratio of the specific scope data and the adjustment scope data set by the operator when a specific video scope is connected is 1.2, when the other predetermined video scope is connected, the automatic adjustment scope data Value is 1.2 times the value of the scope data defined for the video scope. According to such a calculation method, appropriate data suitable for the characteristics of the processor is automatically set. Alternatively, the automatic adjustment scope data setting means may calculate the automatic adjustment scope data based on the difference between the specific scope data and the adjustment scope data. Even when the difference is used, appropriate data can be obtained according to the characteristics of the processor.

When the video scopes are connected to the processor one after another and the data adjusting operation is performed each time, a plurality of scope data and a plurality of adjusting scope data are obtained, and a predetermined scope is obtained based on these data. Automatically adjusted scope data for the videoscope is calculated. Therefore, the scope data ratio is the average value of the ratios of the specific video scopes calculated so far, because automatic adjustment is performed using the value of the adjustment scope data set according to the characteristics of the processor. Is desirable. For the same processor, the scope data corrections tend to be about the same for each video scope. Therefore, the automatic adjustment scope data having a more appropriate value can be obtained by using the average value of the scope data ratios calculated up to that point. On the other hand, when the automatic adjustment scope data is calculated based on the difference between the specific scope data and the adjustment scope data, the average value of the differences in the specific video scopes calculated so far may be used.

Once the adjustment scope data is set according to the data adjustment operation, it is better not to automatically adjust and convert the data when the video scope is connected to the processor again. Therefore, it is preferable that the processor further includes an adjustment state determination unit that determines whether or not the scope data to be automatically adjusted has already been adjusted by a predetermined data adjustment operation. When the automatic adjustment target scope data has already been adjusted by a predetermined data adjustment operation, the automatic adjustment scope data setting means does not convert and set the automatic adjustment scope data to the automatic adjustment scope data. Therefore, the adjusted standard initial data suitable for the characteristics of the processor is maintained unchanged.

A program for executing the scope data setting process of the present invention is a processor of an electronic endoscope apparatus capable of connecting to a plurality of video scopes, and a set of data defined for each of the plurality of video scopes. Is a program executed in a processor having a memory capable of storing a plurality of sets of scope data related to signal processing, and is a set of data defined for each of a plurality of video scopes, and is related to signal processing. According to the memory that can store a set of multiple scope data and the specified data adjustment operation for a specific video scope, the specific scope data that corresponds to the specified data adjustment operation in the set of scope data according to the specified video scope The adjustment scope data that sets the modified adjustment scope data When the data setting means and a specified video scope are connected, the scope data that is automatically adjusted according to the specified scope data in the set of scope data that corresponds to the specified video scope is set to the specified scope data and the adjusted scope data. The automatic adjustment scope data setting means for converting and setting the automatic adjustment scope data calculated based on the values of and is operated.

On the other hand, when it is determined that the video scope 50 has been removed, the process proceeds to step S413, and the display of the scope name is erased from the monitor 32. When step S413 is executed, the subroutine ends.

On the other hand, if it is determined in step S401 that the videoscope 50 is not connected to the processor 10, the process proceeds to step S402.

Here, by comparing the serial number data of the read scope data with the serial number data (see FIG. 2) stored in the memory 26, it is determined whether or not the registration is completed.

If the connected videoscope 50 is already registered in step S404, steps S405 and S406 are skipped and step S4 is executed.

In step S501, it is determined whether or not the B gain data b1 (j) set to 0 or any other value is 0. That is, it is determined whether or not the B gain data of the connected videoscope has already been adjusted. If b1 (j) is not 0, that is, if it is determined that the B gain data has already been adjusted, the process proceeds to step S502, and the value of the B gain data b1 (j) is used as it is as the adjustment scope data of the signal processing circuit 20. It is set in the register. On the other hand, b

Although FIG. 7 shows only the processing for the B gain data, the same processing as for the B gain data is applied to the R gain data, and if the data adjustment is not performed by the operator, r (J) is calculated by the following formula. r (j) = r0 (j) × mrr (6) Further, the same processing as the R and B gain data is applied to the scope data including the delay time data and the CCD gain data. To be done.

As described above, according to the present embodiment, when the video scope 50 is connected to the processor 10, the data which is not adjusted by the operator among the scope data is adjusted by connecting another video scope. It is automatically adjusted based on the convergence average value calculated at some time and set in the register of the signal processing circuit 20. The scope data already adjusted by the operator is directly set in the register of the signal processing circuit 20.

In the present embodiment, the automatic adjustment is performed based on the ratio of the scope data before adjustment and the scope data after adjustment, but the scope data before adjustment and the scope data after adjustment are The automatic adjustment may be performed based on the difference between More generally, in consideration of using other scope data, automatic adjustment may be performed based on the following formula. However, here, only the function of the B gain data in white balance is shown. b (j) = f (b0 (k1) to b0 (km), b1 (k1) to b1 (km)) (7) where f is a function for obtaining B gain data b (j) , B0 (k1) to b0 (km) indicate scope data before adjustment, and b1 (k1) to b1 (km) indicate scope data after adjustment.

More specifically, regarding the R and B gains,
The scope data, the adjustment scope data, the difference between the adjustment scope data and the scope data, and the average value of the differences are r0 (i), b0 (i), r1 (i), and b1 respectively.
(I), dr (i), db (i), mdr, mdb, R and B gain data r in white balance
(J) and b (j) are calculated by the following equations. ("I" is the registration number of the video scope involved in the calculation, "j" is the registration number of the currently connected video scope, and "n" is the number of calculated scope data differences.) Dr (i ) = R1 (i) −r0 (i) (8) db (i) = b1 (i) −b0 (i) (9) mdr = Σdr (i) / n (10) mdb = Σdb (i) / n (11) r (j) = r0 (j) + mdr (12) b (j) = b0 (j) + mdb・ ・ (13)

Considering that the scope data is automatically adjusted to a more appropriate value, the scope data is automatically obtained only with the same type of video scope (stomach observation video scope, large intestine observation video scope, etc.). You may comprise so that each may be adjusted.
