When white balance is adjusted, a scope controller updates and sets a gain value of the adjustment data and transmits the gain value to the processor to update the gain value of the EEPROM of the processor. When a different videoscope is newly connected to the processor, whether or not the videoscope is of the same model of the previously connected videoscope is determined. If it is determined that the videoscope is of the same model, the processor transmits the adjustment data and programs stored in the EEPROM to the currently connected videoscope. The videoscope executes motion processing based on the received adjustment data and programs.

Description

  The present invention relates to an endoscope system that images a subject such as an inner wall of an organ with a scope and displays an observation image on a monitor, and particularly uses data or a program that can be adjusted and updated by a user such as color information data. It relates to the setting process according to the environment.

  A video scope having an image sensor such as a CCD at the tip is provided with a circuit that performs image signal processing on a series of pixel signals read from the image sensor. In this case, signal processing such as color adjustment and gain processing is performed on the pixel signal. Videoscope operation processing including image signal processing is based on the execution of a program stored in advance in memory.

  Image signal processing such as color adjustment performed in the video scope is performed using predetermined parameters (gamma value, gain value, etc.). The parameter depends on the characteristics on the scope side such as the image sensor size (resolution) and is adjusted in advance at the time of shipment and stored in the ROM or the like.

  On the other hand, the color of the observation image varies depending on the type of processor. Specifically, the color tone changes depending on the type of the lamp provided as the light source, the optical system for condensing the lamp light to the light guide in the video scope, and processor characteristics such as the image signal processing circuit.

  Therefore, a color information parameter corresponding to a processor that can be connected in advance is prepared in the video scope, and when the video scope is connected to the processor, the model of the processor is detected, and based on the color information parameter suitable for the connected processor. To perform image signal processing. (See Patent Document 1).

  Alternatively, it is possible for the user to perform color adjustment work such as white balance adjustment before the endoscope work, and to adjust the parameters most suitable for the use environment during the work. In the white balance adjustment work, a video object is imaged by a video scope, and the gain value is set so that the ratio of R, G, and B is 1: 1: 1. During observation using the video scope, a color observation image based on the set gain value is displayed.

JP 2003-284683 A

  The video scope needs to be inspected regularly or irregularly, and if the mechanism or electric circuit inside the scope breaks down, it needs to be repaired. Furthermore, since the video scope is used in another endoscope system, it must be set according to the usage environment.

  When the videoscope is inspected, repaired, or changed according to the usage environment, the parameters that have been set by the user until then are reset. Therefore, when the video scope is used again, the user must perform parameter adjustment work again.

  Further, in new adjustment work, the same setting as before may not be performed. Therefore, when a plurality of video scopes of the same model are used in combination, there is a risk that color information parameters and the like vary between products.

  On the other hand, programs that perform videoscope operation processing are frequently upgraded, but if the videoscope to be repaired or inspected does not support the latest version of the program, it may be necessary to make a new program modification. Come.

  Therefore, it is required to share data or programs among the devices of the endoscope system and automatically set the videoscope-related data or programs that have been used so far according to the operating environment of the endoscope system. It is done.

  The endoscope system of the present invention is used under a usage environment in which a predetermined video scope is selectively connected to a processor from a plurality of video scopes. The video scope includes an image sensor and an image signal processing unit that processes pixel signals read from the image sensor. The video scope can also be used in different endoscopic systems constructed by other processors.

  Each video scope is provided with a memory (hereinafter referred to as a scope-side memory), and data used for image signal processing (hereinafter referred to as adjustment data) executed by the image signal processing unit is determined by its own scope model. It is stored in association with the data shown (hereinafter referred to as scope model data). The adjustment data is one or a plurality of data related to image information processing such as a color information parameter such as a gain value, and is stored in advance in the scope side memory. The scope model data is represented by a code, for example.

  The processor is also provided with a memory (hereinafter referred to as a processor-side memory) so that adjustment data and scope model data sent from the connected videoscope can be stored in association with each other. The processor-side memory is, for example, a built-in memory incorporated in advance in the processor.

  The processor of the present invention, when a predetermined video scope is connected to the processor, a model identity determination means for determining whether the model of the connected video scope is the same model as the previously connected video scope, When the connected video scope is not of the same model, a processor-side adjustment data storage unit that stores adjustment data transmitted from the video scope in association with the scope model data in the processor-side memory is provided.

  Whether or not the video scope is the same model can be determined based on differences in observation target organs, manufacturing time, imaging system characteristics, and the like. For example, if they are the same observation target and the performance (image size, resolution, etc.) of the image sensor is the same, they can be regarded as the same model.

  As a configuration of adjustment data transmission to the processor, for example, when the video scope to be connected is not the same model, the processor includes a processor side transmission request means for requesting transmission of adjustment data, and the video scope includes the Scope-side adjustment data transmission means for transmitting adjustment data in response to a transmission request from the processor may be provided.

  The processor according to the present invention further includes processor-side adjustment data updating means for updating the adjustment data stored in the processor-side memory to the adjustment data after setting in accordance with adjustment data setting work performed by the user while the video scope is connected. Is provided. The adjustment data setting work is a work for setting (customizing) specific adjustment data in accordance with the use environment. For example, when white balance adjustment is performed as the adjustment data setting operation, the R, G, and B gain values are adjusted. At this time, the gain value set in the adjustment data is updated in the processor side memory.

  In order to cause the adjustment data to be updated to be transmitted to the processor, for example, the video scope updates the adjustment data stored in the scope-side memory to the adjustment data after setting according to the adjustment data setting operation. What is necessary is just to provide an update means and a scope side update adjustment data transmission means for transmitting the updated adjustment data to the processor.

  On the other hand, when the connected video scope is the same model, the processor of the present invention reads the adjustment data corresponding to the model from the processor side memory and transmits it to the connected video scope. A transmission means is provided. The video scope includes a scope-side adjustment data resetting unit that changes the adjustment data stored in the scope-side memory to the received adjustment data when the adjustment data is received from the processor when the video scope is connected.

  By such mutual development of data, adjustment data held by the video scope alone is developed and shared in the processor, while when a new video scope is connected, the adjustment data developed in the processor is transferred to the video. Expands to scope. Therefore, video scopes of the same model connected to the processor perform image signal processing based on common adjustment data.

  As the processor-side memory, a portable memory (such as a memory card) that can be detachably attached to the processor can be applied together with the built-in memory. In this case, it is possible to use adjustment data developed and shared by other endoscope systems. For example, when the portable memory is mounted on the processor, the processor-side adjustment data storage means can read adjustment data stored in the portable memory and store it in the built-in memory.

  The endoscope system can be constructed so as to be connected to a server through a network or the like. The server can be connected to various endoscope systems constructed in accordance with the use environment, and the video scope can be used across a plurality of endoscope systems.

  Video scopes used in various endoscope systems are difficult to manage, and may not be recognized by the user even when the video scope needs to be maintained. It is desirable to perform videoscope maintenance management on the server side.

  For this reason, the processor of the present invention includes usage time detection means for detecting the usage time connected when the video scope is detached, and usage time transmission means for transmitting the usage time to the server. Then, based on the usage time sent to the server, the cumulative usage time calculation means for calculating the cumulative usage time representing the total usage time of the video scope, and maintenance is required if the cumulative usage time exceeds the allowable limit time It is only necessary to provide notification means for transmitting data indicating that the data is to the processor. Considering only the configuration for managing the maintenance of the video scope, the configuration for developing and sharing the adjustment data described above is not necessary.

  An endoscope system according to another aspect of the present invention includes an imaging device and a plurality of video scopes each having an image signal processing unit that processes a pixel signal read from the imaging device, and a predetermined one of the plurality of video scopes. An endoscope system including a processor to which a video scope is selectively connected, and a program is shared and deployed.

  That is, in the endoscope system of the present invention, each video scope has a scope-side memory in which a program for executing scope operation processing is stored in association with its own scope model data, and the processor is connected to the video scope. A processor-side memory is provided in which a program sent from the video scope and scope model data are stored in association with each other. When a predetermined video scope is connected, the processor is configured to determine whether or not the connected video scope is the same model as the previously connected video scope, and the connected video scope. Is not the same model, the processor side adjustment data storage means for associating the program and scope model data sent from the video scope and storing them in the processor side memory and the connected video scope are the same model, A processor-side adjustment data transmission unit that reads a program corresponding to the model from the processor-side memory and transmits the program to a connected videoscope, and the videoscope receives adjustment data from the processor when the videoscope is connected. Stored in the scope side memory The program has a scope-side program re-setting means for changing the received program.

  In an endoscope system according to another aspect of the present invention, a plurality of video scopes each provided with an image sensor at the distal end thereof to execute image signal processing, and a predetermined video scope among the plurality of video scopes are selectively used. An endoscope system including a processor connected to the endoscope. The video scope transmits adjustment data related to image signal processing stored in advance in the scope side memory or a program related to scope operation processing to a connected processor. When the processor receives at least one of the adjustment data and the program sent from the connected video scope, the processor stores at least one of the received adjustment data and the program in the processor-side memory.

  When the connected video scope is of the same model as the previously connected video scope, the processor transfers at least one of the adjustment data and the program stored in the processor side memory to the connected video scope. Send. When the video scope receives at least one of the adjustment data and the program from the connected processor, the video scope changes at least one of the adjustment data and the program stored in advance to at least one of the received adjustment data and the program. The video scope and the processor of the endoscope system are constructed as mutually related sub-combinations.

  For example, the video scope updates the adjustment data stored in the scope-side memory to the adjustment data after the setting in accordance with the adjustment data setting operation performed by the user while the video scope is connected, and the updated adjustment data is To the processor.

  As described above, according to the present invention, in the endoscope system, it is possible to perform the endoscope work while automatically sharing the data and the program according to the use environment.

  Below, the endoscope system which is this embodiment is demonstrated with reference to drawings.

  FIG. 1 is a block diagram of an endoscope system according to this embodiment.

  The endoscope system includes a video scope 10 whose insertion portion is inserted into the body, and a processor 20, and the video scope 10 is detachably connected to the processor 20. Various types and types of video scopes are prepared, and a predetermined video scope 10 is selectively connected to the processor 20 in accordance with the endoscopic work. In addition, a monitor 50, a server 60, and a keyboard 70 are connected to the processor 20.

  The processor 20 includes a light source 32 such as a xenon lamp, and illumination light emitted from the light source 32 is incident on a light guide 11 provided in the video scope 10 via a condenser lens 31. The light incident on the light guide 11 exits from the scope tip 10T and is irradiated toward the subject (observation target) through the light distribution optical system 13. A diaphragm 33 for adjusting the amount of illumination light is disposed between the condenser lens 31 and the light guide 11.

  The illumination light reflected by the subject is imaged by the objective lens 15 provided at the scope tip 10T, whereby a subject image is formed on the light receiving surface of the image sensor 12, such as a CCD. In the image sensor 12, an image signal for one frame is read at a predetermined frame time interval (for example, 1/30 second interval) based on the drive signal from the sensor drive circuit 18. The image sensor 12 is provided with a complementary color filter in which color elements composed of Cy, Ye, G, Mg or R, G, B are arranged in a mosaic pattern.

  A series of read pixel signals is sent to the pre-stage signal processing circuit 14. In the pre-stage signal processing circuit 14, the pixel signal is digitized and further subjected to signal processing such as white balance processing (gain processing) and gamma correction processing. As a result, R, G, and B image signals are generated and sent to the subsequent signal processing circuit 22 of the processor 20.

  In the post-stage signal processing circuit 22, contour enhancement processing, superimposition processing, and the like are performed on the image signal and output to the monitor 50 via the output circuit 24. As a result, the observation image is displayed on the monitor 50 as a real-time moving image.

  A system control circuit 26 including a CPU, a ROM, and the like outputs control signals to the timing controller 28, the post-stage signal processing circuit 22, and the like, and controls the operation of the entire processor 20. A program related to the operation control of the processor is stored in the ROM in advance. The system control circuit 26 communicates with the scope controller 16 provided in the video scope 10 to receive and transmit various data, programs, and the like.

  When the video scope 10 is connected to the processor 20, power is supplied from the processor 20 to the video scope 10. A scope controller 16 including a CPU controls the operation of the video scope 10. The EEPROM 19 stores data (hereinafter referred to as adjustment data) and a program related to image signal processing of the video scope, and white balance processing (gain processing) in the pre-stage signal processing circuit 14 is performed on the adjustment data stored in the EEPROM 19. This is executed based on one gain value data (parameter). Also, by executing the program stored in the EEPROM 19, control processing of the entire scope operation such as driving of the image sensor 12 is performed.

  In a situation where the video scope 10 is connected, it is possible to perform the white balance adjustment work for setting the gain value of the white balance processing described above. When a predetermined operation on the keyboard 70 or the front panel button 80 is performed by the user, white balance adjustment for setting a gain value is executed. At this time, a white subject is imaged toward the scope tip 10T, and the gain value is set so that the ratio of R, G, and B image signals is 1: 1: 1.

  In the EEPROM 23 built in the processor 20, adjustment data such as programs and gain values stored in the EEPROM 19 of the video scope 10 are recorded as necessary. The system control circuit 26 writes the program and adjustment data stored in the EEPROM 23 via the memory interface 29 to the memory card 25 that is detachably attached to the processor 20.

  The processor 20 is connected to the server 60 through the network, and the server 60 manages the usage status of the video scope 10 connected to the processor 20. The system control circuit 26 of the processor 20 includes a timer (not shown) that detects the connection time of the video scope 10 connected to the processor 20, and when the connected video scope 10 is removed, The connection time is transmitted to the server 60 as the usage time. Further, along with the usage time, the adjustment data and program of the video scope recorded in the EEPROM 23 are transmitted to the server 60.

  Next, program data mutual communication and recording processing performed between the video scope and the processor will be described with reference to FIGS. In the present embodiment, between a plurality of connectable video scopes and a processor, data related to the video scope, particularly data related to image signal processing, and a program for controlling the operation of the video scope are shared.

  FIG. 2 is a flowchart showing adjustment data, program communication processing, and gain value setting processing executed by the processor. FIG. 3 is a flowchart showing adjustment data, program communication processing, and gain value setting processing executed by the videoscope. FIG. 4 is a diagram showing a procedure for recording the program and the adjustment data in the memory. FIG. 5 is a diagram showing a correspondence table of adjustment data and programs recorded in the video scope and the processor.

  When the video scope 10 of a predetermined model is connected to the processor 20 (S101), it is determined whether or not the connected video scope has been registered (S102). Specifically, it is determined whether or not the currently connected video scope is the same model as the previously connected video scope.

  Videoscope models are classified based on the performance of the organ to be observed and the image sensor 12. For example, if the CCD size and the resolution level are the same in a video scope whose observation target is the upper digestive tract, it is determined that the same model is used. As shown in FIG. 5, programs PA, PB, and PC are prepared for video scopes given model codes (represented as A, B, and C here), respectively. A series of adjustment data ZA, ZB, ZC including a gain value is prepared according to the model codes A, B, C. The program and adjustment data are stored in the EEPROM of the video scope 10 in association with the model code.

  Videoscopes are individually provided with serial numbers (ID numbers). However, if the observation target organs are the same and the performance of the imaging elements is the same, these are regarded as the same model. In the case of the same model, the color tone, resolution, and the like of the image are substantially the same, and data relating to color information such as a gain value can be set to the same value.

  When it is determined that the connected videoscope model is not the same model as the previously connected videoscope, the program stored in the EEPROM 19 of the videoscope and the command data requesting adjustment data including the gain value are displayed in the videoscope. 10 (S103, see FIGS. 4A and 4B).

  In the video scope, when power is supplied through connection to the processor 20, the operation process shown in FIG. 4 is executed by a program provided in advance, and parameters including a gain value are initialized (S201). Then, it is determined whether or not the program and adjustment data transmission request command data is sent from the processor 20 (S202). When the command data of the transmission request in S103 of FIG. 2 is received, the program and adjustment data are transmitted to the processor 20 (S203). At the time of data transmission, the adjustment data and the program are associated with the model code.

  The processor 20 receives the program, adjustment data, and model code sent from the video scope and records them in the EEPROM 23 (S104 and S105 in FIG. 2). In the EEPROM 23, a program and adjustment data are stored in association with the model code (see FIG. 4B).

  Next, the processor 20 determines whether or not white balance adjustment by the user is performed with the video scope connected (S106). When it is determined that the white balance adjustment is performed by the user's keyboard operation or front panel button operation, command data requesting the video scope to perform gain value setting processing is transmitted to the video scope 10 (S107). .

  In the video scope, when command data for gain value setting processing is sent from the processor (YES in S204 in FIG. 3), gain value setting processing is executed (S205 in FIG. 3). At this time, the scope distal end portion 10T of the video scope 10 is covered with a tube for imaging a white subject. Then, the set gain value is transmitted to the processor 20 (S206).

  In the processor, when the gain value is sent, the gain value is overwritten and updated in the adjustment data stored in the EEPROM 23 (S108 and S109 in FIG. 2). As a result, as shown in FIG. 4C, the gain value is recorded in the processor 20 as the latest gain value in the series of adjustment data.

  When the video scope that has been connected so far is removed (S110), the processor 20 determines whether or not a new video scope is connected (S101). When a video scope is newly connected, the video scope is initialized by power supply (S201 in FIG. 3).

  The processor 20 determines whether or not the connected video scope is the same model as the previously connected video scope (S102 in FIG. 2). The determination of the same model is made based on whether or not adjustment data and a program corresponding to the model code exist in the EEPROM 23. If it is determined that the model is the same model, the program and adjustment data corresponding to the model stored in the EEPROM 23 are read and transmitted to the newly connected video scope (S111, S112).

  In the newly connected video scope, when the program and adjustment data corresponding to its own model are sent from the processor 20 (YES in S207 in FIG. 3), the received program and adjustment data are overwritten and updated in the EEPROM 19. (S208). Then, initialization is performed again with the updated program and adjustment data, and adjustment data including a gain value and the like is reset (S209).

  By such mutual communication and recording processing of adjustment data and programs between the video scope and the processor, data related to image signal processing and programs related to video scope operation are successively deployed to the video scope and processor, Data and programs are shared.

  In this embodiment, adjustment data and a program are also memorize | stored in the memory card 25, It is possible to remove a memory card and to expand | deploy data to another processor, ie, an endoscope system. Further, when a memory card storing adjustment data and a program related to a video scope of a model that has not been connected so far is loaded into the processor 20, the information can be taken out. This will be described below with reference to the drawings.

  FIG. 6 is a flowchart showing adjustment data, program recording processing, and reading processing executed in the processor, and is executed by interrupting the main routine of the processor 20. FIG. 7 is a diagram showing the development of the adjustment data and the program.

  When the insertion of the memory card 25 is detected, it is determined whether adjustment data and a program for a model that is not registered in the processor 20 are stored in the inserted memory card 25 (S301, S302). If an adjustment data program of a model that is not stored in the EEPROM 23 of the processor 20 is stored, the adjustment data and program are associated with the model code and read from the memory card (S303).

  This time, the adjustment data and program stored in the video scope 10 are expanded on the memory card 25. That is, when adjustment data and a program are stored in the EEPROM 23 of the processor 20, they are stored in the memory card 25 in association with the model code (S304, S305).

  Since this storing process and reading process are executed as interrupt processes at predetermined time intervals, the latest adjustment data and program in the EEPROM 23, that is, the adjustment data and program set in the video scope are sequentially overwritten and updated in the memory card 25. Is done.

  As shown in FIG. 7, the adjustment data and program stored in the EEPROM 23 of the processor 20 are stored in the memory card 25. Thereby, when the memory card 25 is removed and connected to another processor, the adjustment data and program owned by the video scope connected to the processor 20 are stored in the internal memory of the processor used in the other endoscope system. Is remembered. Thereby, an equivalent use environment is constructed even in an endoscope system using another processor.

  FIG. 8 is a flowchart showing the scope management process including the usage time of the video scope executed by the server.

  In S401, the usage time, adjustment data, and program of the video scope connected to the processor are received from a predetermined processor connected through the network. The usage time and the like are sent in association with the serial code (ID number) of the video scope. In step S402, the accumulated usage time representing the total time of the video scope used so far according to the ID number is calculated. Specifically, the received use time is added to the use accumulated time calculated so far, and a new use accumulated time is calculated. Also, in S402, the usage status of the video scope is detected based on the received adjustment data and program.

  As described above, when a scope is connected or detached, the processor of the endoscope system connected to the server 60 calculates a use period between the scopes and transmits it to the server 60 (the flow is not shown here). ). In an environment where the video scope is used across a plurality of endoscope systems having a network with the server 60, the server 60 can receive the usage time of any video scope for each endoscope system. The server 60 calculates and stores the total usage time of the video scope based on the usage time in each processor. Specifically, when a new usage time is received, the server 60 calculates the total usage time by adding to the previous usage cumulative time.

  If it is determined that the accumulated usage time exceeds a predetermined allowable limit time, data notifying that the video scope needs to be repaired is transmitted to the processor (S404). The threshold is determined in advance according to the performance of the video scope. If the accumulated usage time does not exceed, the follow-up observation is continued (S405). Further, when the necessity of maintenance is detected from the received adjustment data and program other than the accumulated usage time, the fact is notified.

  As described above, according to the present embodiment, when a predetermined video scope 10 is connected to the processor 20, adjustment data and programs related to image processing are transmitted from the EEPROM 19 of the video scope 10 to the EEPROM 23 of the processor 20. When white balance adjustment is performed while the video scope 10 is connected to the processor 20, the gain value of the adjustment data is updated in the video scope 10 and the gain value is also updated in the EEPROM 23 of the processor 20.

  When another video scope is newly connected to the processor 20, it is determined whether or not the video scope is the same model as the video scope that has been connected before. In the case of the same model, the adjustment data and the program stored in the EEPROM 23 are transmitted to the video scope that is currently connected. Then, the video scope performs operation processing including image signal processing based on the received adjustment data and program.

  In the present embodiment, when video scopes of the same model are connected to the processor 20, adjustment data such as a gain value is shared. This eliminates the need for the user to perform white balance adjustment work and the like for each video scope many times. In particular, when adjustment data such as a gain value based on the characteristics of the connected processor, that is, the characteristics of the endoscope system is set, the same model is unified. For this reason, in an endoscope system using the processor between products of the same model, variations such as color adjustment do not occur.

  Furthermore, the program for operating the video scope can be updated to the latest version between the same models, and the video scope having excellent operation performance can be automatically improved.

  On the other hand, in the present embodiment, adjustment data and programs stored in the video scope are stored in the memory card 25. As a result, even in another endoscope system using another processor, it is possible to construct an equivalent use environment when using the same type of video scope, and settings and the like are simplified.

  In addition, since the usage status including the accumulated usage time of a specific videoscope is managed by the server 60, even if the videoscope is reused by various processors, that is, various endoscope systems, the videoscope The total usage time is detected, and the presence or absence of maintenance can be accurately determined and notified.

  As the adjustment data, data other than the gain value, which is changed or updated in accordance with the use environment by the adjustment work or automatic work by the user, can be shared in the same manner. When the image signal processing circuit of the video scope is configured by a circuit that can be constructed by a program such as an FPGA, it is also possible to communicate with each other so that the program that constructs the circuit is shared. A rewritable nonvolatile memory other than the EEPROM may be applied.
