  Hereinafter, an endoscope system according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic view showing a treatment room 500 in which the endoscope system 1 according to the first embodiment of the present invention is installed. As shown in FIG. 1, in the treatment room 500, the bed on which the patient K lies and the endoscope system 1 of the present embodiment are arranged. FIG. 2 is a block diagram showing a configuration of the endoscope system 1. In the present embodiment, the endoscope system 1 includes an endoscope 100, a processor 200, a human sensor 600, and an RFID tag 700. The proximal end of the endoscope 100 is connected to the processor 200. The processor 200 integrally includes an image processing device that processes an image signal output from the endoscope 100 and generates an image, and a light source device that illuminates a body cavity that does not reach natural light via the endoscope 100. Device. In another embodiment, the image processing device and the light source device may be configured separately.

  As illustrated in FIG. 2, the processor 200 includes a system controller 202 and a timing controller 204. The system controller 202 controls each element constituting the endoscope system 1. The timing controller 204 outputs a clock pulse for adjusting the signal processing timing to various circuits in the endoscope system 1.

  The lamp 208 emits illumination light after being started by the lamp power igniter 206. As the lamp 208, a high-intensity lamp such as a xenon lamp, a halogen lamp, a mercury lamp, or a metal halide lamp is suitable. Illumination light emitted from the lamp 208 is condensed by the condenser lens 210, adjusted to an appropriate amount of light through the stop 212, and enters an incident end of an LCB (Light Carrying Bundle) 102.

  A motor 214 is mechanically connected to the diaphragm 212 via a transmission mechanism such as an arm or a gear (not shown). The motor 214 is a DC motor, for example, and is driven under the drive control of the driver 216. The diaphragm 212 is operated by the motor 214 to change the opening degree so as to make the image displayed on the monitor 300 have an appropriate brightness, and limits the amount of illumination light emitted from the lamp 208 according to the opening degree. . The appropriate reference for the brightness of the image is changed according to the brightness adjustment operation of the front panel 218 by the operator. Note that the dimming circuit that controls the brightness by controlling the driver 216 is a well-known circuit, and a description thereof will be omitted in this specification.

  Various forms of the configuration of the front panel 218 are assumed. As a specific configuration example of the front panel 218, a hardware key for each function mounted on the front surface of the processor 200, a touch panel GUI (Graphical User Interface), a combination of a hardware key and a GUI, and the like are assumed.

  The illumination light incident on the incident end of the LCB 102 propagates by repeating total reflection in the LCB 102. The illumination light propagated through the LCB 102 is emitted from the exit end of the LCB 102 disposed at the distal end of the endoscope 100. Illumination light emitted from the exit end of the LCB 102 illuminates the subject via the light distribution lens 104. The reflected light from the subject forms an optical image at each pixel on the light receiving surface of the solid-state image sensor 108 via the objective lens 106.

  The solid-state imaging device 108 is, for example, a single-plate color CCD (Charge Coupled Device) image sensor having a Bayer-type pixel arrangement, accumulates an optical image formed by each pixel on the light receiving surface as a charge corresponding to the amount of light, The image signal is converted into an image signal corresponding to each color of R, G, and B. The converted image signal is amplified by the preamplifier 110 and then input to the signal processing circuit 220 via the driver signal processing circuit 112. In another embodiment, the solid-state image sensor 108 may be a complementary metal oxide semiconductor (CMOS) image sensor.

  The timing controller 204 supplies clock pulses to the driver signal processing circuit 112 in accordance with timing control by the system controller 202. The driver signal processing circuit 112 drives and controls the solid-state imaging device 108 at a timing synchronized with the frame rate of the video processed on the processor 200 side in accordance with the clock pulse supplied from the timing controller 204.

  The driver signal processing circuit 112 reads the identification information of the endoscope 100 by accessing the memory 114. The identification information of the endoscope 100 includes, for example, the number of pixels of the solid-state image sensor 108, sensitivity, a corresponding rate, a model number, and the like. A distinction between gastrointestinal endoscopy and lower gastrointestinal endoscopy can also be specified. The driver signal processing circuit 112 outputs the identification information read from the memory 114 to the system controller 202.

  An operation button 120 is provided on the operation unit (not shown) of the endoscope 100. The operation of the operation button 120 is detected by the system controller 202 via the driver signal processing circuit 112. Illustration of the connection between the operation button 120 and the driver signal processing circuit 112 is omitted. The doctor D who is an operator performs imaging of the object in the body cavity of the patient while controlling the operation of various functional units of the endoscope 100 through the operation of the operation button 120.

  The signal processing circuit 220 includes an image processing circuit 222, a color adjustment circuit 224, and an image output circuit 226. The signal processing circuit 220 inputs the image signal output from the driver signal processing circuit 112 to the image processing circuit 222. The image processing circuit 222 performs image processing such as clamping, knee, gamma correction, interpolation processing, AGC (Auto Gain Control), A / D conversion, noise removal, and color conversion on the input image signal. The image signal that has undergone various types of image processing is output to the color adjustment circuit 224.

  The human sensor 600 is provided in the vicinity of the automatic door 400 of the treatment room 500. In the present embodiment, the power of the endoscope system 1 is turned on prior to the procedure using the endoscope 100, and the human sensor 600 is a patient K or a doctor D who enters the treatment room 500 from the automatic door 400. , And outputs a sensing signal to the image processing apparatus 200 of the endoscope system 1. The endoscope system 1 attempts wireless communication with the RFID tag 700 by the wireless module 230 using a sensing signal as a trigger (details will be described later).

  In the present embodiment, the RFID tag 700 is a passive tag that does not need to incorporate a battery for operation, and operates using radio waves from the wireless module 230 as an energy source. In addition, a radio wave transmission method in wireless communication between the wireless module 230 and the RFID tag 700 is an electromagnetic induction method in which coils are arranged in the wireless module 230 and the RFID tag 700 and the coils are magnetically coupled to each other to transmit energy and signals. Alternatively, the radio module 230 and the RFID tag 700 may be provided with antennas, and radio waves that transmit energy and signals by exchanging radio waves with each other's antennas may be used. In general, when a passive tag is used, the communicable distance is about 1 m at the maximum in the electromagnetic induction method and about 5 m at the radio method, so the transmission method to be used is appropriately selected according to the operating environment of the endoscope system 1. That's fine. Since the passive tag is a well-known RFID tag, detailed description is omitted in this specification.

  When receiving the radio wave output from the wireless module 230, the RFID tag 700 rectifies the received radio wave into a direct current by a rectifier circuit (not shown) in the RFID tag 700, and this is incorporated in the RFID tag 700 as a direct current power source. IC (Integrated Circuit; not shown) is activated. Further, when returning a part of the received radio wave as a reflected wave to the wireless module 230, the RFID tag 700 superimposes setting parameter information related to image processing recorded in the RFID tag 700 on the reflected wave.

  Here, details of processing executed by the wireless module 230, the human sensor 600, the RFID tag 700, and the like in the present embodiment will be described. The human sensor 600 detects a person who has passed through the automatic door 400 of the treatment room 500 and outputs a detection signal to the system controller 202. When a sensing signal is input from the human sensor 600, the system controller 202 controls the wireless module 230 and tries wireless communication with the RFID tag 700.

  The wireless module 230 changes the intensity of the radio wave transmission output stepwise using an attenuator (not shown) or the like. When the intensity of the transmission output decreases, the maximum distance at which communication with the RFID tag 700 can be performed is also shortened. Therefore, the wireless module 230 determines whether or not communication with the RFID tag 700 is possible based on the intensity of the radio wave transmission output, and the wireless module 230 and the wireless module 230 based on the minimum transmission output intensity that can establish communication with the RFID tag 700. The distance from the RFID tag 700 is estimated. The accuracy of estimating the distance between the wireless module 230 and the RFID tag 700 is improved as the intensity increase / decrease width when the intensity of the radio wave transmission output is changed stepwise. Details of each component and function of the endoscope system 1 will be described later.

  FIG. 3 is a block diagram illustrating setting change of image processing using the RFID tag 700 according to the present embodiment. In FIG. 3, only the RFID tag 700, the wireless module 230, the system controller 202, the memory 228, and the color adjustment circuit 224 are shown, and illustration and description of other components are omitted. FIG. 4 is a flowchart of color setting change processing executed in the endoscope system 1 of the present embodiment. This flowchart is executed by the system controller 202 controlling each component in the endoscope system 1. For convenience of explanation, the processing step is abbreviated as “S” in the explanation and drawings in this specification.

  As shown in FIG. 4, first, in step S <b> 101, the system controller 202 determines whether there is a person who has passed through the automatic door 400 based on a detection signal from the human sensor 600. If no sensing signal is output from the human sensor 600 (S101: NO), S101 is repeated until a sensing signal is output. In this embodiment, when the doctor D passes through the automatic door 400, the human sensor 600 outputs a detection signal notifying that a person has been detected to the system controller 202. When the system controller 202 receives a sensing signal from the human sensor 600 (S101: YES), the system controller 202 proceeds to S103 and starts polling by the wireless module 230 (searching for the RFID tag 700 using the wireless module 230). Next, the process proceeds to S105.

  In S105, the communication trial frequency parameter i is reset to “0”. Here, the communication trial number parameter i is a variable for counting the number of executions of communication trial processing (S107) with the RFID tag 700 described later. Next, the process proceeds to S107. In S107, the wireless module 230 attempts wireless communication with the RFID tag 700, and determines whether the wireless communication has been established. The wireless module 230 performs polling while gradually changing the intensity of the radio wave transmission output. When the doctor D approaches the processor 200 and moves to an area where the wireless module 230 and the RFID tag 700 carried by the doctor D can perform wireless communication (wireless communicable area), the wireless module 230 moves to the RFID tag 700. The wireless communication can be established by receiving the reflected wave from (S107: YES). Then, the wireless module 230 outputs the setting parameter acquired from the RFID tag 700 to the system controller 202. Next, the process proceeds to S109. In S <b> 109, the system controller 202 stores the setting parameter output from the wireless module 230 in the memory 228. Next, the process proceeds to S111.

  Here, as shown in FIG. 3, in the present embodiment, the RFID tag 700 has the name (“Dr. A”) of the doctor D as a setting parameter for changing the setting of image processing in the signal processing circuit 220. ), Preferred color setting when performing upper gastrointestinal endoscopy (“upper: redness + 5 blueness-5”), preferred color setting when performing lower gastrointestinal endoscopy (“lower: redness-3”) Blue +1 ”) is recorded. Further, the system controller 202 acquires the endoscope identification information of the endoscope 100 stored in the memory 114 of the endoscope 100 via the driver signal processing circuit 112 when the endoscope system 1 is turned on. To do. Therefore, in S111, the system controller 202 specifies the observation target of the procedure by the doctor D based on the endoscope identification information, and selects the color setting corresponding to the observation target from the setting parameters stored in the memory 228. Thus, the color setting of the color adjustment processing in the color adjustment circuit 224 is changed.

  For example, when the endoscope identification information can identify that the endoscope 100 is used for upper gastrointestinal endoscopy, the system controller 202 sets the upper gastrointestinal endoscopy among the setting parameters stored in the memory 228. Select the color setting ("Upper: Red + 5 Blue-5") for mirror observation. The system controller 202 changes the color setting of the color adjustment circuit 224 using the selected setting parameter, and then ends this flowchart. The system controller 202 does not execute this flowchart again until the procedure by the doctor D is completed. For this reason, the doctor D can perform observation from an image in which a favorite color setting according to the observation target is reflected from the start to the completion of the procedure.

  In S107 of this flowchart, when the wireless module 230 cannot establish wireless communication with the RFID tag 700 because the doctor D is not within the wireless communication possible area of the wireless module 230 (S107: NO), the process proceeds to S113. In S113, the communication trial number parameter i is incremented by one. Next, the process proceeds to S115. In S115, it is determined whether or not the communication trial number parameter i has reached a predetermined upper limit value. This upper limit value is appropriately set according to the operating environment of the endoscope system 1 in consideration of the size of the treatment room 500 and the approximate time required for the doctor to move into the wireless communicable area of the wireless module 230. do it.

  If the communication trial number parameter i has not reached the upper limit (S115: NO), the process returns to S107, and the wireless module 230 tries the wireless communication with the RFID tag 700 again. If the wireless module 230 cannot establish wireless communication with the RFID tag 700 and the communication trial number parameter i reaches the upper limit value by repeating S107, S113, and S115 (S115: YES), the color of the color adjustment circuit 224 This flowchart is ended without changing the setting. For this reason, the system controller 202 sets the color adjustment circuit 224 using a predetermined color setting. The above is the description of this flowchart.

  The color adjustment circuit 224 performs color adjustment processing on the image signal output from the image processing circuit 222 based on the color setting set as described above, and outputs the color-adjusted image signal to the image output circuit 226. The image output circuit 226 buffers the input image signal in a frame memory (not shown) for each color of R, G, and B for each color signal in units of frames. Each buffered color signal is swept from the frame memory at a timing controlled by the timing controller 204, and converted into a video signal conforming to a predetermined standard such as NTSC (National Television System Committee) or PAL (Phase Alternating Line). Converted. The converted video signals are sequentially output to the monitor 300, whereby the image of the subject is displayed on the display screen of the monitor 300.

  As described above, in the present embodiment, when the doctor D enters the treatment room 500, the endoscope system 1 sets the color setting according to the preference of the doctor D according to the observation target to the color adjustment processing of the color adjustment circuit 224. Since the reflection is automatically performed, the doctor D does not have to change the color setting by operating the endoscope system 1.

  Next, a second embodiment of the present invention will be described. For convenience of explanation, the same components as those in the first embodiment are denoted by the same reference numerals, and illustration and description thereof are omitted.

  As shown in FIG. 5, in the present embodiment, the doctor D first performs the procedure for the patient K as in the first embodiment, and the doctor D ′ moves to the treatment room while the doctor D performs the procedure for the patient K. It is assumed that the doctor D 'is replaced with the doctor D to perform the procedure after entering the room 500. The doctor D carries the RFID tag 710, and the doctor D 'carries the RFID tag 720. In this embodiment as well, the RFID tags 710 and 720 are assumed to be passive tags as in the first embodiment. FIG. 6 is a block diagram for explaining setting change of image processing using the RFID tags 710 and 720 in the present embodiment. FIGS. 7A and 7B are flowcharts of image processing setting change executed in the endoscope system 1 ′ of the present embodiment. The process of S201-S215 is a process performed when the doctor D performs the procedure of the patient K similarly to 1st Embodiment. Note that the processing contents of S201 to S215 (excluding S209 and S211) are the same as S101 to S115 (excluding S109 and S111) of the first embodiment, and thus description thereof is omitted.

  The processing in S209 and S211 will be described with reference to FIG. 6, only the RFID tags 710 and 720, the wireless module 230, the system controller 202, the memory 232, and the color adjustment circuit 224 are shown as in FIG. 3, and illustration and description of other components are omitted. As illustrated in FIG. 6, identification information (doctor name “Dr. A”) of the doctor D used to change the setting of the image processing is recorded in the RFID tag 710 carried by the doctor D. The RFID tag 720 carried by the doctor D ′ stores the identification information (doctor name “Dr. B”) of the doctor D ′ as in the RFID tag 710. Further, the memory 232 of the system controller 202 stores in advance a data table in which favorite color settings for image processing for each observation target of the doctors D and D ′ are stored. It should be noted that the memory 232 is not limited to the doctors D and D ′ but may store in advance the color settings of other doctors who have used the endoscope system 1 ′ in the past or plan to use it in the future. Good.

  In step S <b> 209, the system controller 202 refers to the data table in the memory 232, and the endoscope identification information acquired from the memory 114 via the driver signal processing circuit 112 of the endoscope 100 and the identification acquired from the RFID tag 710. Based on the information “Dr. A”, a favorite color setting of the doctor D corresponding to the observation target is selected. For example, if the endoscope 100 can be identified from the endoscope identification information as an endoscope that performs lower gastrointestinal endoscopic observation, the system controller 202 stores “Dr. A” stored in the memory 232 as “ Select the color setting of “Lower: Red-3, Blue + 1”. In step S211, the system controller 202 changes the color setting of the color adjustment circuit 224 using the selected color setting, and ends this flowchart.

  Next, a change in the color setting of the color adjustment circuit 224 when the doctor D 'enters the treatment room 500 during the procedure by the doctor D will be described with reference to FIG. FIG. 7B is a flowchart of a timer interrupt routine executed during use of the endoscope system 1 '. In the present embodiment, the timer interrupt routine is executed at predetermined time intervals (for example, every 10 seconds). When the doctor D ′ enters the treatment room 500 from the automatic door 400, since there are two doctors D and D ′ in the treatment room 500, the system controller 202 controls the wireless module 230, It communicates with both the RFID tag 710 carried by the doctor D and the RFID tag 720 carried by the doctor D ′, and specifies which one is performing the procedure.

  When this timer interrupt routine is started, first, S219 is executed. In S219, the system controller 202 controls the wireless module 230 to perform wireless communication with the RFID tags 710 and 720, determines which RFID tag is close to the wireless module 230 (that is, the processor 200), and wireless module The doctor who carries the RFID tag on the side close to 230 is specified as the doctor who is performing the procedure. Specifically, the minimum transmission when the wireless module 230 attempts wireless communication with the RFID tags 710 and 720 while changing the intensity of the radio wave transmission output and establishes wireless communication with each of the RFID tags 710 and 720. The output intensity value is output to the system controller 202. Then, the system controller 202 estimates the distance between the wireless module 230 and the RFID tags 710 and 720 based on the intensity values of the respective transmission outputs that are input, and the currently used (set) RFID tag is determined. It is determined whether or not it is at the closest position.

  As described above, in this embodiment, since the doctor D has entered the treatment room 500 first, the color adjustment circuit 224 has the identification information (“Dr. A”) of the RFID tag 710 carried by the doctor D. The color adjustment processing is executed using the color setting changed based on (). Accordingly, when the doctor D ′ enters the treatment room 500 and determines that the distance between the RFID tag 720 and the wireless module 230 carried by the doctor D ′ is shorter than the distance between the RFID tag 710 and the wireless module 230 ( (S219: YES), it is determined that the procedure is being performed in place of the doctor D ′, and the process proceeds to S221, where the distance between the RFID tag 720 and the wireless module 230 is equal to or greater than the distance between the RFID tag 710 and the wireless module 230. (S219: NO), it is determined that the procedure is continuously performed by the doctor D, and this timer interruption routine is terminated.

  In S <b> 221, the system controller 202 refers to the data table in the memory 232 and uses the endoscope identification information of the endoscope 100 and the identification information (“Dr. B”) of the RFID tag 720 output from the wireless module 230. Based on this, the favorite color setting of the doctor D ′ corresponding to the observation object is selected. For example, if the endoscope 100 can be identified from the endoscope identification information as an endoscope that performs upper gastrointestinal endoscopic observation, the system controller 202 stores “Dr. B” stored in the memory 232 as “ Select the color setting of “Upper: Red + 1 Blue-1”. In step S223, the system controller 202 changes the color setting of the color adjustment circuit 224 using the selected color setting, and ends the interrupt routine. As a result, the monitor 300 outputs an observation image that has been subjected to color adjustment processing according to the preference of the doctor D 'who changed the procedure.

  Thus, in the present embodiment, the wireless module 230 communicates with both the RFID tag 710 carried by the doctor D and the RFID tag 720 carried by the doctor D ′, and identifies which doctor is performing the procedure. The color setting of the color adjustment circuit 224 is automatically changed based on the identification information of the RFID tag of the doctor identified as performing the procedure. Therefore, even when there are a plurality of doctors in the treatment room 500, an observation image subjected to color adjustment processing according to the preference of the doctor during the procedure is output.

  The above is the description of the embodiment of the present invention. The present invention is not limited to the above-described configuration, and various modifications can be made within the scope of the technical idea of the present invention. For example, in the above description, the RFID tag is a passive tag. However, as described above, the distance relationship between doctors is specified by the wireless module using an active tag or a semi-active tag in which an operation battery is incorporated in the RFID tag. The color setting can be changed.

  In the above description, the setting of the process of the color adjustment circuit 224 among the processes in the signal processing circuit 112 is changed. However, other processes of the signal processing circuit 112 may be used instead of or in addition to the setting parameters. It is also possible to record the setting parameter relating to the image in an RFID tag or a memory and change settings of various processes in the image processing.

  In the above description, the observation target is specified based on the endoscope identification information of the endoscope 100. However, the patient information of the patient K who performs the procedure using the endoscope 100 is displayed on the front panel 218, for example. It may be configured to operate and store in advance in the memory 228 and specify the observation target using the patient information instead of the endoscope identification information. Also, only one type of setting parameter may be provided for each observation target. In this case, since the color setting can be appropriately changed based on the information acquired from the RFID tag without acquiring the identification information of the endoscope 100, it is based on the identification information of the endoscope 100 as described above. The effect of the present invention can be obtained while simplifying the configuration by omitting the determination.
