JP, 2009-065643, A

  In the technology described in Patent Document 1, although it is possible to dynamically change the configuration to use any unused lane for another application as described above, the operation of the unused lane can be performed. It is impossible to reduce power consumption by stopping or limiting the operation.

  An object of the present technology is to reduce power consumption.

The concept of this technology is
A data communication unit connected to a plurality of data transmission lanes of the interface cable and performing data communication with an external device;
According to another aspect of the present invention, an electronic apparatus includes a control unit configured to selectively control the states of the plurality of data transmission lanes to a lane state for reducing power consumption.

  In the present technology, the electronic device is connected to an external device by an interface cable. The data communication unit performs data communication with an external device through the plurality of data transmission lanes of the interface cable. The control unit selectively controls the states of the plurality of data transmission lanes to a lane state for reducing power consumption. For example, the lane state for reducing the power consumption may be set to the communication stop state (sleep state) or the communication restricted state (standby state).

  As described above, in the present technology, the states of the plurality of data transmission lanes are selectively controlled to the lane state for reducing power consumption. Therefore, it is possible to reduce the power consumption by controlling the state of the unused data transmission lane to the communication stop state or the communication restriction state.

  In the present technology, for example, a control communication unit connected to one control data transmission lane of the interface cable and performing control communication with an external device is further provided, and the control unit controls the control communication in the control communication unit. In response, the state of a plurality of data transmission lanes may be controlled. For example, when the control communication unit starts control communication with an external device, the control communication unit may transmit a command for requesting start of control communication to the external device through the control data transmission lane.

  For example, the control communication unit may transmit a state transition request command including lane information and lane state information to the external device through the control data transmission lane. For example, the control communication unit may be configured to receive a state transition request command including lane information and lane state information from the external device through the control data transmission lane.

  For example, the control communication unit may transmit a status notification request command including lane information to the external device through the control data transmission lane. For example, the control communication unit may be configured to receive a status notification request command including lane information from the external device through the control data transmission lane.

  For example, the control communication unit may transmit a state notification command including lane information and lane state information to the external device through the control data transmission lane. For example, the control communication unit may be configured to receive a status notification command including lane information and lane status information from an external device through the control data transmission lane.

Also, the other concept of this technology is
A data communication unit connected to a plurality of data transmission lanes of the interface cable and performing data communication with an external device;
A control communication unit connected to one control data transmission lane of the interface cable and performing control communication with the external device;
According to another aspect of the present invention, there is provided an electronic apparatus including a control unit configured to selectively control the state of the control data transmission lane to a lane state for reducing power consumption.

  In the present technology, the electronic device is connected to an external device by an interface cable. The data communication unit performs data communication with an external device through the plurality of data transmission lanes of the interface cable. The control communication unit performs control communication with an external device through one control data transmission lane of the interface cable. The state of the control data transmission lane is selectively controlled to the lane state for reducing power consumption. For example, the lane state for reducing the power consumption may be set to the communication stop state (sleep state) or the communication restricted state (standby state).

  As described above, in the present technology, the state of the control data transmission lane is selectively controlled to the lane state for reducing power consumption. Therefore, when the control data transmission lane is in the unused state, the state of the control data transmission lane can be controlled to the communication stop state or the communication limited state to reduce the power consumption.

  In the present technology, for example, an operation unit may be further provided to restore the state of the control data transmission lane in the lane state for reducing power consumption to the active state. In this case, when the user operates the operation unit, it is possible to easily restore the state of the control data transmission lane in the lane state for reducing power consumption to the active state.

  According to the present technology, power consumption can be reduced. The effects described in the present specification are merely examples and are not limited, and additional effects may be present.

<1. Embodiment>
[Data transmission system configuration]
FIG. 1 shows the configuration of an AV (Audio and Visual) transmission system 10 according to an embodiment. The AV transmission system 10 includes an electronic device 100A, an electronic device 100B, and an interface cable 200 for connecting these electronic devices. For example, the electronic device 100A is a source device such as a Blu-ray disc recorder, and the electronic device 100B is a sink device such as an image display device.

  The interface cable 200 has a plurality of signal lines 201. The signal line 201 may be a copper wire when performing communication by electricity, and may be an optical fiber when performing communication by light. Each of the electronic devices 100A and 100B includes a data transmitting / receiving unit 101 as a data communication unit performing data communication, a control command transmitting / receiving unit 102 as a control communication unit performing control communication, and a state of a lane configured by signal lines 201. The lane controller 103 controls the lanes.

  Among the plurality of signal lines 201, one used for one control data transmission lane (hereinafter, appropriately referred to as “control lane”) is connected to the control command transmission / reception unit 101 of the electronic device 100A and the electronic device 100B. Further, among the plurality of signal lines 201, those used for a plurality of data transmission lanes (hereinafter, appropriately referred to as “data lanes”) are connected to the data transmission / reception unit 101 of the electronic device 100A and the electronic device 100B.

  Communication of control commands, that is, control communication is performed by the control command transmission / reception unit 102 of the electronic device 100A and the electronic device 100B, and lane state control is performed by the lane control unit 103 according to the control communication.

  The electronic device 100A and the electronic device 100B may be capable of bi-directional communication in one lane, or the present technology is also applicable to a configuration in which a pair of two lanes is used for unidirectional communication and bi-directional communication in one lane. is there.

  FIG. 2 shows the definition of the lane state. In this embodiment, there are five lane states: idle (IDLE), active (ACTIVE), link up (LINKUP), standby (STANDBY), and sleep (SLEEP).

  The idle state is a state of waiting for communication and, for example, transmitting and receiving data meaningless to communication (such as padding data). The active state is a state in which normal communication is in progress and data such as AV data and control commands are being transmitted and received. The link up state is a state in which the clock synchronization operation of the lanes is performed to perform normal communication.

  The standby state is a communication restricted state in which the amount of data to be transmitted / received is restricted although communication is not stopped. The sleep state is a communication stop state, and consumes the least power among all the states. In this embodiment, the standby state and the sleep state constitute a lane state for reducing power consumption.

  FIG. 3 shows a flowchart of lane control communication start processing. At the start of processing, the control lane is in the active state, and the data lane is in the idle state. In step S1, by performing control communication start processing in the control lane, exchange of commands between devices using the control lane becomes possible.

  In step S1, a control communication start request command and a response command (COMMCNTL: communication control command) are mutually transmitted / received between the connected devices, and both connected devices enter a control communication start state in the control lane. If the control lane is in the communicable state, state control of the other lanes (data lanes) is possible.

  FIG. 4 shows the flow of transmission and reception of the COMMCNTL command. Here, for example, the initiate side (Initiate side) is the electronic device 100A of FIG. 1, and the response side (Response side) is the electronic device 100B of FIG.

  The initiate side requests start of control communication by "COMMCNTL (request)". The response side sends "Acknowledgement + COMMCNTL (request) (request approval)" as a response to the request from the initiation side. Then, the initiation side that has received the request acknowledge sends "Acknowledgement", and the lane control communication start processing is completed. Although not shown, the request can also be rejected by sending "Not Acknowledgement" instead of "Acknowledgement".

  FIG. 5 shows a transition diagram of data lane states. The state of the data lane is changed by the request / response of the lane configuration change command (LCNF command) in the control lane. Transition from the sleep (SLEEP) state or the standby (STANDBY) state to the active (ACTIVE) state TR1 and TR2 are started by the LCNF command.

  Thereafter, the state is shifted to the link up (LINKUP) state, and after synchronization of the lanes, the transition TR3 becomes active (active). This transition TR3 is an automatic transition. In order to notify the connected device that the link-up state has transitioned to the active state, a lane status information command (LSIF command) is sent using the control lane. By receiving the LSIF command, it is possible to know that the target lane of the connection destination has transitioned to the active state. Other state transitions are controlled by the LCNF command.

  FIG. 6 shows the flow of transmission and reception of the LCNF command. Here, for example, the initiate side (Initiate side) is the electronic device 100A of FIG. 1, and the response side (Response side) is the electronic device 100B of FIG.

  The initiation side sends a state transition request to the response side by specifying “value” which is the state of the transition destination of the lane specified by “lane” by “LCNF (request, lane, value)”. The response side returns the received request to the initiation side as "acknowledgement + LCNF (lane, value)" as a response to the request from the initiation side.

  Then, the initiation side that received this return sends "Acknowledgement" to the response side, and the state transition processing is completed, and the lane specified by "lane" on the start side and response side becomes the state specified by "value". And transition. Although not shown, the request can also be rejected by sending "Not Acknowledgement" instead of "Acknowledgement".

  FIG. 7 shows a transmission / reception flow of LSIF commands. Here, for example, the initiate side (Initiate side) is the electronic device 100A of FIG. 1, and the response side (Response side) is the electronic device 100B of FIG.

  FIG. 7A shows an example of “Transmission / reception method 1” in which a request is made from the initiation side to the response side and the initiation side receives notification of the lane state from the response side.

  The initiate side requests the response side to notify the status of the lane specified by "lane" by "LSIF (request, lane)". The response side returns “value”, which is the state of the lane specified by “lane”, to the start side as “acknowledgement + LSIF (value, lane)” as a response to the request from the start side.

  Then, the initiation side receiving this return sends "Acknowledgement" to the response side, and the status notification request processing is completed. Although not shown, the request can also be rejected by sending "Not Acknowledgement" instead of "Acknowledgement".

  FIG. 7 (b) shows an example of "Transmission / reception method 2" in which the lane state is notified unilaterally from the initiation side to the response side. The initiation side notifies the response side of "value" which is the state of the lane designated by "lane" by "LSIF (value, lane)". The response side receiving this notification sends "Acknowledgement" to the initiation side, and the status notification processing is completed.

  The “transmission / reception method 2” may be used when notifying the connection destination device that the link-up state has transitioned to the active state. As a result, it is possible to check without polling in the transmission / reception method 1 as to whether or not the data lane of the connection destination device has transitioned from the link-up state to the active state.

  FIG. 8 shows a transition diagram of control lane states. The control lane can control the state of the control lane itself in addition to controlling the state transition of the data lane. The state control of the control lane is performed by the request / response of the LCNF command, similarly to the state control of the data lane.

  The control lane can transition from the active state to the standby state at transition TR4 and from the active state to the sleep state at transition TR5. Such a transition is performed, for example, in the active state when nothing is transmitted on the control line for a predetermined time or more. The control lane can transition from the standby state to the sleep state at transition TR8 under the condition that a certain time has elapsed or the device power is turned off after transition from the active state to the standby state at transition TR4. It is.

  When the control lane transitions to the standby state at transition R4, the control lane is in the communication restriction state, and thus transition to the active state by communication of a command in the control lane is not possible. When the control lane is in the standby state, the transition to the active state via the link-up state TR6 is not performed by transmitting / receiving a command, but is performed by transmitting / receiving a specific waveform, for example.

  The method of notifying the connection destination device that the link-up state has transitioned to the active state is the same as that of the data lane. The control command transmission / reception unit 10 can not process the status notification request of the LSIF command from the connection destination device when in the link up state. In this case, "Transmission / reception method 2" in FIG. 7B is effective.

  When the control lane transitions from the active state to the sleep state at transition TR5, for example, an instruction from the upper layer (a system controller of the device, etc.) in response to the user performing a reset operation such as power off at the operation unit. To perform the transition TR7 to reset the system and perform control communication start processing again. When reset is performed, the control lane transitions to the active state via the link-up state, or transitions to the active state in response to user operation after transitioning to the standby state.

Transition of control lane from standby state to active state
Here, details of the case where the transition to the active state when the control lane is in the standby state are performed by transmitting and receiving a specific waveform will be described with reference to FIGS. 9 to 12.

  First, the conditions under which the transition from the active state to the standby state is performed are defined. The transition from the standby state to the active state is performed when at least one of the following two conditions is satisfied. Here, for example, it is assumed that the communication device (control command transmission / reception unit 102) of the electronic device 100A, 100B has a reception unit "Sub stream link Rx ch" and a transmission unit "Sub stream link Tx ch".

Condition 1: The standby state Sub stream link Rx ch must detect an active transition request signal from the opposite Tx ch.
Condition 2: Implementation-dependent condition. For example, a transition instruction from the user to the active state, etc.

  In addition, the communication device that has received the active transition request signal at the time of transition to the active state outputs an active transition acknowledgment signal (Accept Activation Response) from Tx ch if transition to the active state is possible. The active transition acknowledgment signal is defined, for example, as follows for Tx ch and Rx ch in consideration of the loss of a cable or the like used for connection.

  The active transition acknowledgment signal output from Tx channel of Sub stream link is a signal having an average power equal to or greater than Pth_Tx continuing during Tact (an electrical signal when signal line 201 is a copper wire, signal line 201 is an optical fiber) In some cases it is an optical signal). In addition, the active transition acknowledgment signal input to Rx ch of Sub stream link is a signal having an average power of Pth_Rx or more that continues during Tact.

  Here, Tx ch of the communication apparatus that outputs the active transition request signal continues to transmit average power of Pth_Tx or more continuing for Twait_act to the opposite Sub stream link Rx ch.

  If it does not receive an active transition acknowledgment signal from the opposite Sub stream Tx ch during this Twait_act, the opposite communication apparatus deems that the active state transition is rejected, and the transition to the active state is cancelled. Here, Twait_act is an upper limit time (for example, 1300 ms) at which the communication apparatus that has output the active transition request signal waits for reception of the active transition acknowledgment signal from the opposite communication apparatus, and outputs power of Pth_Tx or more during Twait_act. Is synonymous with continuously outputting the active transition request signal a plurality of times.

  FIG. 9 is a flowchart showing an example of an operation flow in the case of transitioning from the standby state to the active state in response to an active transition instruction from the user. First, the communication apparatus (control command transmission / reception unit 102) continues to wait for an active transition instruction from the user (S302). The communication apparatus, when there is an active transition instruction from the user (YES in S302), transitions Sub stream link Rx to active state (S304). Furthermore, the communication apparatus continues to transmit an active transition request signal from the Sub stream link Tx ch to the opposite communication apparatus (S306).

  Subsequently, the communication apparatus waits for an active transition acknowledgment signal from the opposite communication apparatus (S308). If the active transition acknowledgment signal is not received after the predetermined waiting time Twait_act has elapsed (NO in S308 and YES in S310), the communication apparatus increases the power supply value of Power Profile until the Power Profile is maximized ( S316), Steps S306 to S314 are repeated. Even when the Power Profile is maximum (YES in S312), when the active transition acknowledgment signal is not received, the communication apparatus cancels the transition to the active state, and standbys the Rx ch and Tx ch of the Sub stream link. Transition to

  On the other hand, when the communication apparatus receives the active transition acknowledgment signal within the predetermined waiting time Twait_act (YES in S308), the communication apparatus transitions the Sub stream link Tx ch to the active state (S316).

  FIG. 10 is a flowchart showing an example of an operation flow in the case of transiting to the active state by the active transition request signal from the opposite communication apparatus. First, the communication apparatus continues to wait for reception of an active transition request signal from the opposite communication apparatus (S402). When the communication apparatus receives an active transition request signal from the opposite communication apparatus (YES in S402), the communication apparatus determines whether or not transition to an active state is possible (S404). If it is not possible to transition to the active state (NO in S404), the communication apparatus does not transmit an active transition acknowledgment signal to the opposite communication apparatus, and does not transition to the active state. On the other hand, when it is possible to shift to the active state (YES in S404), the communication apparatus transmits an active transition approval signal to the opposite communication apparatus (S406). Subsequently, the communication apparatus transitions to the active state (S408).

  FIG. 11 is a timing chart showing an example of a signal output from the Tx ch of each communication device when transition from the standby state to the active state is possible. The master device (for example, the recording device) that has been in the standby state starts transitioning to the active state at time t31. Furthermore, the master device starts transmitting an active transition request signal to the slave device (for example, TV) in the standby state at time t33 when the start time Twp of the analog front end has elapsed from time t31.

  On the other hand, the detection unit of the slave device is in a state capable of detecting a signal at time t32 when the intermittent non-operation time Tdwn has elapsed from the previous intermittent operation.

  At time t34 when the time Tc necessary for the signal rise and the predetermined time Tact have further elapsed from time t33, the slave device determines that the active transition request signal has been received, and starts transmission of the active transition acknowledgment signal.

  The master device receives an active transition approval signal at time t37 when a predetermined time Tact has elapsed from time t36 when a time Tc necessary for signal rise has elapsed from time t35 when a start time Twp of an analog front end has elapsed from time t34. judge. After time t38 when the master device and the slave device both transition to the active state and training of the output signal is completed, the master device and the slave device output normal signals.

  FIG. 12 is a timing chart showing an example of a signal output from the Tx ch of each communication apparatus when transition from the standby state to the active state is not possible. The master device in the standby state starts transitioning to the active state at time t41. Furthermore, the master device starts transmitting an active transition request signal to the slave device in the battery out state at time t42 when the start time Twp of the analog front end has elapsed from time t41.

  However, since the slave device is in the battery out state, it can not transmit an active transition acknowledgment signal. At time t43 when a predetermined waiting time Twait_act has elapsed from time t42, the master device cancels the transition to the active state and transitions to the standby state. When the master device supplies power to the slave device via the IF cable, as described with reference to FIG. 9, the master device changes the Power Profile to increase the power supply value, and then re-executes. It may be attempted (send an active transition request signal).

  As described above, in the AV transmission system 10 shown in FIG. 1, the states of a plurality of data transmission lanes (data lanes) can be selectively controlled to the lane state for reducing power consumption. Therefore, it is possible to reduce the power consumption by controlling the state of the unused data transmission lane to the communication stop state (sleep state) or the communication restricted state (standby state).

  Here, an example of power consumption suppression by reducing the number of used lanes will be described. For example, consider a case where the data rate to be transmitted is 50 Gbps in a total of 12 lane interface cables in which one lane has a transmission band of 12 Gbps. At this time, if there are six lanes in total including one control lane and five data lanes (12 Gbps × 5 lanes), data transmission of 50 Gbps is possible. Therefore, the remaining six lanes are unnecessary for data transmission, and by putting the lanes in the sleep state or the standby state, the power consumed in the unnecessary data lanes can be reduced.

  Further, in the AV transmission system 10 shown in FIG. 1, the state of one control data transmission lane (control lane) can be selectively controlled to the lane state for reducing power consumption. Therefore, it is possible to reduce power consumption by controlling the state of the unused control data transmission lane to the communication stop state (sleep state) or the communication limited state (standby state).

According to the control, after the endoscope 5115 at the tip of the arm 5145 is moved from any position to any position, the endoscope 5115 can be fixedly supported at the position after the movement. The arm 5145 may be operated by a so-called master slave method. In this case, the arm 5145 can be remotely controlled by the user via the input device 5161 installed at a location distant from the operating room.

  Further, when force control is applied, the arm control device 5159 receives the external force from the user and moves the actuator of each joint 5147 a to 5147 c so that the arm 5145 moves smoothly following the external force. So-called power assist control may be performed. Thus, when the user moves the arm 5145 while directly touching the arm 5145, the arm 5145 can be moved with a relatively light force. Therefore, it is possible to move the endoscope 5115 more intuitively and with a simpler operation, and the convenience of the user can be improved.

  Here, in general, in endoscopic surgery, the endoscope 5115 is supported by a doctor called scopist. On the other hand, by using the support arm device 5141, the position of the endoscope 5115 can be more reliably fixed without manual operation, so that it is possible to stably obtain an image of the operative site. , Can be performed smoothly.

  The arm control device 5159 may not necessarily be provided in the cart 5151. Also, the arm control device 5159 may not necessarily be one device. For example, the arm control device 5159 may be provided at each joint 5147a to 5147c of the arm 5145 of the support arm device 5141, and the arm control devices 5159 cooperate with one another to drive the arm 5145. Control may be realized.

(Light source device)
The light source device 5157 supplies the endoscope 5115 with illumination light for imaging the operative part. The light source device 5157 is configured of, for example, a white light source configured by an LED, a laser light source, or a combination thereof. At this time, when a white light source is configured by a combination of RGB laser light sources, the output intensity and output timing of each color (each wavelength) can be controlled with high accuracy. Adjustments can be made. Further, in this case, the laser light from each of the RGB laser light sources is irradiated on the observation target in time division, and the drive of the imaging device of the camera head 5119 is controlled in synchronization with the irradiation timing to cope with each of RGB. It is also possible to capture a shot image in time division. According to the method, a color image can be obtained without providing a color filter in the imaging device.

  In addition, the drive of the light source device 5157 may be controlled to change the intensity of the light to be output at predetermined time intervals. The drive of the imaging element of the camera head 5119 is controlled in synchronization with the timing of the change of the light intensity to acquire images in time division, and by combining the images, high dynamic without so-called blackout and whiteout is obtained. An image of the range can be generated.

  In addition, the light source device 5157 may be configured to be able to supply light of a predetermined wavelength band corresponding to special light observation. In special light observation, for example, the mucous membrane surface layer is irradiated by irradiating narrow band light as compared with irradiation light (that is, white light) at the time of normal observation using the wavelength dependency of light absorption in body tissue. The so-called narrow band imaging (Narrow Band Imaging) is performed to image a predetermined tissue such as a blood vessel with high contrast. Alternatively, in special light observation, fluorescence observation may be performed in which an image is obtained by fluorescence generated by irradiation with excitation light. In fluorescence observation, a body tissue is irradiated with excitation light and fluorescence from the body tissue is observed (autofluorescence observation), or a reagent such as indocyanine green (ICG) is locally injected into the body tissue while being locally injected. What irradiates the excitation light corresponding to the fluorescence wavelength of the reagent, and obtains a fluorescence image etc. can be performed. The light source device 5157 can be configured to be able to supply narrow band light and / or excitation light corresponding to such special light observation.

When the imaging unit 5123 is configured as a multi-plate type, a plurality of lens units 5121 are also provided corresponding to each imaging element.

  In addition, the imaging unit 5123 may not necessarily be provided in the camera head 5119. For example, the imaging unit 5123 may be provided inside the lens barrel 5117 immediately after the objective lens.

  The drive unit 5125 is constituted by an actuator, and moves the zoom lens and the focus lens of the lens unit 5121 by a predetermined distance along the optical axis under the control of the camera head control unit 5129. Thereby, the magnification and the focus of the captured image by the imaging unit 5123 may be appropriately adjusted.

  The communication unit 5127 is configured of a communication device for transmitting and receiving various types of information to and from the CCU 5153. The communication unit 5127 transmits the image signal obtained from the imaging unit 5123 to the CCU 5153 via the transmission cable 5179 as RAW data. At this time, it is preferable that the image signal be transmitted by optical communication in order to display the captured image of the surgical site with low latency. During the operation, the operator 5181 performs the operation while observing the condition of the affected area by the captured image, and for safer and more reliable operation, the moving image of the operation site is displayed in real time as much as possible It is because that is required. In the case where optical communication is performed, the communication unit 5127 is provided with a photoelectric conversion module which converts an electrical signal into an optical signal. The image signal is converted into an optical signal by the photoelectric conversion module, and then transmitted to the CCU 5153 via the transmission cable 5179.

  The communication unit 5127 also receives, from the CCU 5153, a control signal for controlling the drive of the camera head 5119. The control signal includes, for example, information indicating that the frame rate of the captured image is designated, information indicating that the exposure value at the time of imaging is designated, and / or information indicating that the magnification and focus of the captured image are designated, etc. Contains information about the condition. The communication unit 5127 provides the received control signal to the camera head control unit 5129. The control signal from the CCU 5153 may also be transmitted by optical communication. In this case, the communication unit 5127 is provided with a photoelectric conversion module that converts an optical signal into an electric signal, and the control signal is converted into an electric signal by the photoelectric conversion module and is then provided to the camera head control unit 5129.

  Note that imaging conditions such as the frame rate, the exposure value, the magnification, and the focus described above are automatically set by the control unit 5177 of the CCU 5153 based on the acquired image signal. That is, so-called AE (Auto Exposure) function, AF (Auto Focus) function, and AWB (Auto White Balance) function are installed in the endoscope 5115.

  The camera head control unit 5129 controls the drive of the camera head 5119 based on the control signal from the CCU 5153 received via the communication unit 5127. For example, the camera head control unit 5129 controls the drive of the imaging element of the imaging unit 5123 based on the information to specify the frame rate of the captured image and / or the information to specify the exposure at the time of imaging. In addition, for example, the camera head control unit 5129 appropriately moves the zoom lens and the focus lens of the lens unit 5121 via the drive unit 5125 based on the information indicating that the magnification and the focus of the captured image are designated. The camera head control unit 5129 may further have a function of storing information for identifying the lens barrel 5117 and the camera head 5119.

  By disposing the lens unit 5121 and the imaging unit 5123 in a sealed structure having high airtightness and waterproofness, the camera head 5119 can have resistance to autoclave sterilization.

  Next, the functional configuration of the CCU 5153 will be described. The communication unit 5173 is configured of a communication device for transmitting and receiving various information to and from the camera head 5119. The communication unit 5173 receives an image signal transmitted from the camera head 5119 via the transmission cable 5179. At this time, as described above, the image signal can be suitably transmitted by optical communication. In this case, in accordance with the optical communication, the communication unit 5173 is provided with a photoelectric conversion module which converts an optical signal into an electrical signal. The communication unit 5173 provides the image processing unit 5175 with the image signal converted into the electrical signal.

  In addition, the communication unit 5173 transmits, to the camera head 5119, a control signal for controlling the drive of the camera head 5119. The control signal may also be transmitted by optical communication.

  The image processing unit 5175 performs various types of image processing on an image signal that is RAW data transmitted from the camera head 5119.

When the image processing unit 5175 is configured by a plurality of GPUs, the image processing unit 5175 appropriately divides the information related to the image signal, and performs image processing in parallel by the plurality of GPUs.

  The control unit 5177 performs various types of control regarding imaging of the surgical site by the endoscope 5115 and display of the imaged image. For example, the control unit 5177 generates a control signal for controlling the drive of the camera head 5119. At this time, when the imaging condition is input by the user, the control unit 5177 generates a control signal based on the input by the user. Alternatively, when the endoscope 5115 is equipped with the AE function, the AF function, and the AWB function, the control unit 5177 determines the optimum exposure value, focal length, and the like according to the result of the detection processing by the image processing unit 5175. The white balance is appropriately calculated to generate a control signal.

  In addition, the control unit 5177 causes the display device 5155 to display an image of the operative site based on the image signal subjected to the image processing by the image processing unit 5175. At this time, the control unit 5177 recognizes various objects in the operation site image using various image recognition techniques. For example, the control unit 5177 detects a shape, a color, and the like of an edge of an object included in an operation part image, thereby enabling a surgical tool such as forceps, a specific living body region, bleeding, mist when using the energy treatment tool 5135, etc. It can be recognized. When displaying the image of the operation unit on the display device 5155, the control unit 5177 uses the recognition result to superimpose various operation support information on the image of the operation unit. The operation support information is superimposed and presented to the operator 5181, which makes it possible to proceed with the operation more safely and reliably.

  A transmission cable 5179 connecting the camera head 5119 and the CCU 5153 is an electric signal cable corresponding to communication of an electric signal, an optical fiber corresponding to optical communication, or a composite cable of these.

  Here, in the illustrated example, communication is performed by wire communication using the transmission cable 5179, but communication between the camera head 5119 and the CCU 5153 may be performed wirelessly. When the communication between the two is performed wirelessly, it is not necessary to lay the transmission cable 5179 in the operating room, so that the movement of the medical staff in the operating room can be eliminated by the transmission cable 5179.
