Description

  The present invention relates to a display / operation method and a program for performing firmware update of a remote operation device from the image capture device in an image capture device that wirelessly receives an operation command and a remote operation device that transmits the operation command to the image capture device.

  In recent years, accessories such as Bluetooth Low Energy (trademark), which have begun to become popular, use wireless systems with very low power consumption, and establish communication only when communication is necessary. Low current consumption is realized by putting itself into a resting state.

  The imaging device is equipped with a relatively large battery, and a device that is based on the assumption that the user periodically replaces the battery can be put into a communication standby state at any time. In this case, the battery is not replaced every time shooting is performed. Therefore, it is activated only when the user performs a button operation, establishes communication with the imaging device, and transmits and receives information.

  In the case of Bluetooth Low Energy (registered trademark), the communication device is divided into a central device and a peripheral device for communication. Peripheral devices transmit signals called advertisements at regular intervals to appeal their presence. When the central apparatus receives the advertisement signal, the central apparatus transmits a connection request if the apparatus itself intends to connect. After transmitting the advertisement signal, the peripheral device waits for a connection request for a certain period. If a connection request is received during that time, a connection response is returned to the central device, thereby establishing a connection between the central peripheral devices.

  For example, when the camera side is a peripheral and the remote control side is central, when the release button of the remote control is pressed, the remote control activates the wireless communication circuit and waits for an advertisement signal at regular intervals. When an advertisement signal issued by a camera during standby is received, a connection request is transmitted to the camera, and communication is established between the camera and the remote controller. The camera receives information on the pressed button and starts autofocus. When in-focus shooting starts, the remote control side is notified of shooting execution, and the remote control turns on the LED to notify the user that the shutter has been released, disconnects the connection, and returns to the sleep state again.

  On the other hand, when the camera side is central and the remote control side is a peripheral, when the release button of the remote control is pressed, the remote control activates the wireless communication circuit in response to this and starts transmission of an advertisement signal at regular intervals. Since the camera always waits for an advertisement signal, communication is established with this as a trigger. That is, the timing for establishing communication is inevitably when the remote control is operated.

  Conventionally, for an accessory device attached to an imaging device, a function of updating the firmware of the accessory device by operating a menu on the UI of the imaging device is provided. The imaging apparatus can establish communication with the conventional accessory device at an arbitrary timing and receive information from the connected accessory device. Therefore, when the user accesses the firmware update function on the UI of the imaging device, it can communicate with the accessory device and display device information including the firmware version of the accessory device on the UI of the imaging device. It was. However, in the case of a device that is activated only when a user operation is performed, such as the remote controller, the version cannot be displayed only by camera operation.

  As a method of solving this problem, for example, as in Patent Document 1, a method of storing and storing information acquired from a peripheral device and displaying the information can be considered.

JP 2005-78343 A

  However, the method of Patent Document 1 has a problem that the firmware update can be performed by another camera, and the stored version notation may be different from the actual one. Therefore, an object of the present invention is to provide a UI that does not display erroneous information by changing the timing at which the firmware version is displayed on the imaging device for accessory devices that require special operations to establish communication. is there.

In order to achieve the above object, the present invention provides:
A communication means (140) for communicating with a plurality of accessory devices by a plurality of communication methods;
Version acquisition means (102, 140, 116) for acquiring the firmware version of the accessory device;
Firmware data acquisition means (102, 118, 119, 120) for retrieving the firmware file of the accessory device from the storage medium;
Accessory device firmware update means (102, 118, 119, 120, 140) for performing firmware update of the accessory device by communication with the accessory device;
Accessory equipment that does not require special operation of the accessory equipment to establish communication; and
Version display means (102, 117, 118, 140, S602) for changing the timing of displaying the firmware version of the accessory device with the accessory device that requires special operation of the accessory device to establish communication;
It is characterized by providing.

  ADVANTAGE OF THE INVENTION According to this invention, it can prevent displaying an inappropriate version on an imaging device about the accessory apparatus which requires special operation for communication connection.

The main CPU (102) includes an image processing circuit, performs image processing such as contour correction, gamma correction, and white balance correction on the input digital signal, and outputs it to the volatile memory (119). . As described above, the imaging control unit (114), the A / D converter (115), and the main CPU (102) function as image processing means.

  Further, the main CPU (102) has a file generation function, converts the image signal generated by performing the above-described image processing into a predetermined file format such as JPEG format or MOV format, performs compression processing, and performs image processing. Generate data. Further, the main CPU (102) also has recording means, and records the image data generated by the file generation function on the recording medium (120).

  The photometric sensor (112) is a device that measures the amount of light obtained through the photographing lens (107), and the main CPU (102) is based on the amount of light measured by the photometric sensor (112). Determine the appropriate exposure. When the exposure amount is determined, the main CPU (102) controls the sensor sensitivity (ISO sensitivity) of the imaging device (110) via the imaging control unit (114). The shutter driving device (113) controls the aperture of the taking lens (107) by the aperture (108) and the time control for releasing the shutter (109) to supply light to the image sensor (110) by the shutter device (109). ) Through.

  The distance measuring sensor (111) is composed of a sensor such as a CCD or CMOS corresponding to the distance measuring point, and outputs a distance measuring point deviation signal corresponding to the distance to the subject to the main CPU (102). The operation system switch group (116) sets a power button of the imaging device, a release button for performing a shutter operation, validity / invalidity of the wireless transfer function, and identification number information of the remote operation device (201) as a wireless connection partner It is a group of switches for operating the imaging device (101).

  The display circuit (117) is composed of a color liquid crystal, and information in the imaging device (101) is displayed when the main CPU (102) functions as a display means. The display content includes details of the imaging device (101) such as image data recorded in the non-volatile memory (118), information relating to shooting data, and information on the remote operation device (201) to which the imaging device (101) is connected. There are various setting states.

  In this embodiment, the wireless communication circuit (104) is assumed to be a Bluetooth Low Energy (trademark) peripheral. In addition to Bluetooth Low Energy (trademark), this embodiment can be realized if packet communication can be realized between the imaging device (101) and the remote operation device (201). Therefore, in the present invention, other packet communication means (ANT or Zigbee (trademark) represented by IEEE 802.15.4) may be used. In many cases, the wireless communication CPU (103), the wireless communication circuit (104), the nonvolatile memory (138), and the volatile memory (139) are integrated as one wireless communication unit (140). In particular, the wireless communication circuit and the wireless communication CPU may not be clearly separated.

  For the sake of explanation, in this embodiment, the wireless communication circuit (104) and the wireless communication CPU (103) are described separately. The wireless communication CPU (103) is a CPU for controlling the wireless communication circuit (104) to perform wireless communication with the remote operation device. The operation is performed using the volatile memory (139) as a storage area in accordance with a program stored in advance in the nonvolatile memory (138).

  The wireless communication CPU (103) receives power from the power supply circuit (130) and controls the wireless communication circuit (104) even when the image pickup apparatus has not been operated for a certain period of time and is turned off (hereinafter referred to as auto power off). That is, wireless communication can be continued. Further, when it is detected that an operation has been performed with the remote operation device while the imaging device is in auto power off, the imaging device can be returned from the auto power off state by notifying the main CPU (102).

  Hereinafter, in this embodiment, a case where Bluetooth Low Energy (trademark) is used as the wireless communication means will be described.

  A modulated wireless signal transmitted from the remote operation device (201) is received via the antenna (105), and the digital data demodulated by the wireless communication circuit (104) is notified to the wireless communication CPU (103). The wireless communication CPU (103) analyzes the digital data and notifies the main CPU (102) when it detects that some operation has been performed on the remote operation device.

  The main CPU (102) executes a predetermined operation by an operation performed on the remote operation device. For example, if the release button (207) is pressed on the remote operation device, the imaging device (101) demodulates the message received from the remote operation device via the antenna (105) by the wireless communication circuit (104). To the wireless communication CPU (103). The wireless communication CPU (103) notifies the main CPU (102) that the operation has been performed by the remote operation device. The main CPU (102) determines from the information notified from the wireless communication CPU (103) that the operation performed on the remote operation device is a press of the release button (207), and drives the shutter drive device (113). The shooting operation can be executed.

  The imaging device (101) can also transfer data to the remote operation device (201). In that case, the digital signal notified from the main CPU (102) to the wireless communication CPU is modulated in the wireless communication circuit (104) and transmitted to the remote operation device (201) via the antenna (105). Become. Here, a communication interface between the imaging device (101) and the remote operation device (201) will be described.

  In this embodiment, it is assumed that a small amount of data is exchanged between the imaging device (101) and the remote operation device (201). Therefore, the communication interfaces of the wireless communication circuit (104), the wireless communication CPU (103), and the main CPU (102) are assumed to be communication interfaces such as general SPI and UART, not high-speed communication. Since the present embodiment also holds for interfaces other than those described above, the interface (121) will not be referred to hereinafter.

  Next, description on the remote operation device (201) will be given with reference to FIG. The remote operation device (201) is equipped with a main CPU (202). The main CPU operates when power is turned on from the power supply circuit (230). When the power is turned on, the main CPU (202) performs the overall operation in the remote operation device (201) using the volatile memory (211) as a storage area in accordance with a program stored in advance in the nonvolatile memory (210). To control. The remote operation device includes an operation member such as a release button (207) or an immediate / 2 second changeover switch (206) for designating a waiting time until shooting when the release button is pressed. ).

  As described in FIG. 2, the wireless communication circuit (203) modulates a command notified from the main CPU (202) and transmits it to the imaging device (101) via the antenna (204). Circuit. In this embodiment, the wireless communication circuit (203) is assumed to be Bluetooth Low Energy (trademark) central.

  When the release button (207) is pressed by the user, the main CPU (202) detects an interruption of the user input. It is possible to notify the imaging apparatus (101) via the wireless communication circuit (203) as the user input information of the immediate / 2 second changeover switch state and the release button pressed state.

  Further, the remote operation device (201) includes a display circuit (209), and the main CPU (202) controls various states such as execution results of processing on the remote operation device and the imaging device side by the user. Shown in For example, when an LED is mounted as a display circuit, the main CPU (202) indicates that shooting has been performed in order to indicate to the user that the release button has been pressed, and as a result, shooting has been performed on the imaging device side. The LED is controlled by a lighting / flashing pattern indicating.

  Up to this point, the configuration of the remote photographing system according to the present proposal, the imaging device, and the remote operation device have been described.

  Next, regarding the operation flow of the remote imaging system in the present embodiment, the imaging apparatus side will be described using FIG. 4, and the remote operation apparatus side will be described using FIG. In addition, in order for the imaging device (101) and the remote operation device (201) to recognize the connection target device, it is necessary to hold mutual connection information. Although the procedure for exchanging connection information is called pairing, in this embodiment, description will be made on the assumption that pairing has already been completed.

  Next, FIG. 4A shows a flow at the time of performing an advertising operation to appeal that the wireless communication unit (140) of the imaging device (101) exists as a Bluetooth Low Energy (registered trademark) peripheral. In the case of Bluetooth Low Energy (registered trademark), the connection is usually disconnected except when necessary for power saving operation. When in the auto power-off state, the wireless communication unit (140) of the imaging device (101) operates intermittently at a predetermined interval (S410), and an advertisement signal including connection information of the own device is used as a specific wireless communication channel. Transmit (S411).

When an advertisement signal is transmitted, the same data is transmitted several times at a time because it may not reach due to the radio wave condition. If there is no response from the Bluetooth Low Energy (registered trademark) central device even if it is transmitted a plurality of times (S412), the device again enters a sleep state and waits for the next timing (S413).
When the imaging device receives the connection request transmitted from the remote operation device (201) of the Bluetooth Low Energy (trademark registration) central to the advertisement (S412), the wireless communication unit (140) between the remote operation device and the imaging device A connection is established (S414). When the imaging apparatus main body is automatically powered off (S415), the main CPU is activated (S416), and an operation from the remote operation device is set as an activation factor (S417).

  Thereafter, when a message transmission request from the main CPU (102) to the remote operation device is received (S430), the message is transmitted to the remote operation device (S431). When a response message is received from the remote controller (S432), the main CPU is notified of the received message (S433). When a response message cannot be received from the remote operation device for a certain time (S434), a timeout message is transmitted to the main CPU (S435), and the connection with the remote operation device is terminated (S436).

  When the message from the main CPU is a connection termination request, or when the message is not received from the main CPU for a predetermined time (S437), the connection with the remote operation device is also terminated (S436).

  Next, FIG. 4B shows a flow when the main CPU (102) of the imaging device (101) is activated from the wireless communication unit (140). When the main CPU (102) is in a dormant state, if it receives some external interrupt (S440), it returns from the dormant state (S441). After the activation, the main CPU (102) activates peripheral devices connected to the inside and outside of the main CPU (S442), and performs an initialization process (S443) to activate the imaging apparatus main body.

  Thereafter, the cause of activation of the main CPU (102) is confirmed (S444). When the activation factor is an operation request from the remote operation device (S445), the wireless communication unit (140) is requested to transmit a message requesting user input information acquisition to the remote operation device (S446).

  Subsequently, a predetermined time is waited until a response is received from the wireless communication unit (140) in response to the user input information acquisition request (S447, S448). When user input information is received from the wireless communication unit (140) (S447), the pressed button is processed (S449), and a connection termination request with the remote operation device is transmitted (S450).

  Next, an operation flow on the remote imaging device side will be described. FIG. 5 shows a flow when there is an input from the user to the operation members (206, 207) of the remote operation device. When the user presses the release button (207) (S501), the main CPU (202) of the remote operation device (201) receives an interrupt and returns from the sleep state (S502). The selection state of the immediate / second switching switch (206) and the fact that the release button has been pressed are stored in the volatile memory (211) (S503), and scanning is performed for a paired imaging device that is transmitting an advertisement signal. (S504).

  Since the advertisement signal is transmitted to a predetermined band channel, the scan of the imaging apparatus is to receive a signal transmitted to the band channel and search for a packet including connection information of the paired imaging apparatus. Represents. Since the advertisement message is transmitted in an intermittent operation, it is necessary to continue scanning for a preset time (S505, S506). If the advertisement from the paired imaging device cannot be received after a predetermined time (S506), the display circuit (209) indicates that the operation request has timed out (S507), and the processing when the button is pressed is performed. finish.

  When an advertisement message transmitted from a paired imaging device is received (S505), a connection request is transmitted to establish a Bluetooth Low Energy (registered trademark) connection with the imaging device (S513), and a message is received from the imaging device. (S514). When receiving a message from the imaging device (S517), when the received message is a user input information acquisition request (S518), the main CPU (202) sends the user input information stored in S503 to the wireless communication unit (140). To the imaging device (S531).

  When the received message is not a user input information acquisition request (S518) and the message requires a response (S521), the main CPU (202) transmits a response message via the wireless communication circuit (203). (S522). When the user input information is a release button press, a series of transactions is performed until a message is sent from the imaging apparatus after the user input information is transmitted to inform the user that shooting has been performed. When a series of transactions is completed (S532), the connection is terminated (S533), and the process returns to the dormant state.

  If a message is not received for a predetermined time in S514 (S517), after the LED has finished blinking, the LED is blinked with a lighting / flashing pattern indicating a timeout (S530), and the connection is terminated (S533). Return to hibernation.

  As described with reference to FIG. 5, the remote operation device is normally in a dormant state and cannot communicate with the outside without input from the user. When performing firmware update of the remote operation device from the imaging device, user input on the remote operation device side is essential. A processing flow in the case where such firmware update of the remote operation device is performed from the imaging device will be described with reference to FIG.

  FIG. 6A shows a processing flow of the imaging apparatus when firmware update is selected from the menu of the imaging apparatus by the user. The imaging device checks accessory devices from the setting parameters and the state of electrical contacts, creates a list of accessory devices that can update firmware from the imaging device, and displays a list on the screen (S601).

  Subsequently, for each accessory device, it is confirmed whether the device can establish communication without any special operation on the accessory device side (S602). In the case of an accessory device that does not require a special operation, firmware version information is acquired (S603), and the firmware version is displayed on the screen (S604). On the other hand, if the accessory device requires a special operation (S602), the firmware version is not displayed (S606). All the accessory devices listed are checked (S605), and the process waits for user input.

  FIG. 6B illustrates a processing flow of the imaging apparatus when the user selects the firmware update of the remote operation apparatus from the screen of the imaging apparatus. The imaging apparatus shifts to a mode for performing firmware update of the remote operation device (S611), and displays a screen for prompting the operation of the remote operation device (S612). In the firmware update mode, the imaging apparatus is not powered off for a certain period regardless of the auto power-off time setting of the imaging apparatus. Here, when the firmware update cancel operation is performed by the user (S613), the firmware update mode ends (S615).

  When the user performs a button operation on the remote operation device according to the screen display of the imaging device, a connection request is received from the remote operation device side (S614), and a connection with the remote operation device is established (S619).

  After the connection is established, the imaging device transmits a user input information acquisition request to the remote operation device (S620). When the user input information notification is received from the remote operation device (S621), the remote operation device is notified of the firmware update state (S622). When receiving the firmware update status notification, the remote operation device notifies the firmware version information. When this is received (S623), the current firmware version information of the remote operation device is displayed on the screen of the imaging device (S624). .

  In this way, when the current version information is received from the remote operation device, it is shown to the user, thereby preventing the wrong version information of the remote operation device from being shown to the user. After displaying the current version information of the remote operation device, when the user instructs to perform further firmware update (S626), the screen displays the valid remote operation device firmware file name stored in advance in the storage medium (120). It is displayed above (S627). At this time, if a cancel operation is performed by the user (S631), the firmware update mode is terminated (S639).

  When the firmware is selected by the user (S630), the file size of the firmware is transmitted to the remote operation device (S633), and notification that the update has been performed is notified (S634).

  When receiving the update execution state notification, the remote operation device transmits a firmware data transmission request including the data start position and reception size information in order to receive firmware data in a divided manner. Upon receiving the firmware data transmission request (S635), the imaging apparatus transmits firmware data for the requested size from the requested start position (S636), and updates the progress status of the progress screen (S637). When all the firmware data transmission has been completed (S638), the firmware update mode is terminated (S639).

  Next, the processing flow of the remote operation device will be described with reference to FIGS. 5 and 6C. In the processing flow of FIG. 5, the remote operation device returns from the resting state when an operation member such as the release button (206) is operated (S502). When a paired imaging device is detected (S505), a connection is established (S513), a user input information acquisition request is received (S517), and a user input information notification is transmitted to the imaging device (S531).

  When the imaging device is not in the firmware update state, the imaging device operates according to the user input information and notifies the remote operation device of the result. However, when the imaging apparatus is in the firmware update state, a firmware update state notification is transmitted in response to the user input information notification from the remote operation device. FIG. 6C shows a processing flow when a firmware update state notification is received from the imaging apparatus in the processing flow S517 of FIG.

  The remote operation device shifts to the firmware update mode when receiving the firmware update status notification from the paired imaging device (S650), and transmits firmware version information to the imaging device (S651). When the remote operation device shifts to the firmware update mode, the remote operation device maintains a connection for a longer period than usual even if no message is received from the imaging device. This is because user operations are involved on the imaging device side, but if there is no notification of the firmware file size from the imaging device even after a predetermined time has elapsed (S656), the firmware update mode is terminated (S657). The connection is disconnected (S658).

  After the firmware version information is transmitted, when the firmware file of the remote operation device is determined by the user operation of the imaging device, the remote operation device receives a firmware file size notification from the imaging device (S652).

  Here, functions relating to self-writing in firmware update of the main CPU (202) and the nonvolatile memory (210) of the remote operation device (201) will be described. The nonvolatile memory (210) that stores the firmware of the remote operation device (201) has two program areas, and the firmware written in one of the program areas is executed on the main CPU (202). The other program area that is not executed can be written in accordance with an instruction from the main CPU (202) during firmware execution, and this function is called self-writing.

  A function to smoothly update the firmware is provided by switching and resetting the system for starting the firmware after the firmware writing is normally completed. The remote operation device uses this function to realize a function of updating its own firmware while receiving firmware data from the imaging device in a divided manner.

  When the firmware update status notification is received from the imaging device (S660), the remote operation device divides the firmware data into a plurality of times and receives the firmware data transmission request including the firmware data start position and transmission size (S661). ).

  Firmware data is received from the imaging device (S662), self-writing is performed in the program area of the nonvolatile memory (210) that is not currently operating (S663), and the next firmware data transmission request is transmitted (S661). This process is repeated until the reception and writing of all firmware data is completed (S664), the system for starting the firmware is switched (S670), the connection is disconnected (S671), and the reset is performed (S672).

  The UI of the imaging apparatus that realizes the processing flow when the firmware update of the remote operation apparatus is performed from the imaging apparatus will be described with reference to FIG. FIG. 7 shows a screen transition related to firmware update displayed on the liquid crystal monitor (117) of the imaging apparatus.

  FIG. 7A shows a screen on which a setting menu (500) is displayed. One of a plurality of setting items is firmware update (501), which is selected by the user. In this state, when the user presses the enter button (116), the processing after the processing flow S601 in FIG. 6A is executed, and the processing transitions to FIG. 7B.

  FIG. 7B is a screen on which a menu for firmware update (510) is displayed. The firmware update target includes an imaging device (512) and a remote operation device (513), and the remote operation device is selected by the user. In the firmware update target, the current firmware version is known and displayed for the imaging device, but the remote operation device does not display the version because communication has not been established in this situation. Note that a function for interrupting the firmware update by a user operation and returning to the setting menu is provided (514). When the determination button (116) is pressed with the remote operation device selected, the process proceeds to FIG. 7 (c).

  FIG. 7C shows a state in which firmware update of the remote operation device is selected, and corresponds to the processing flows S611 and S612 in FIG. On the screen, the user is instructed to perform an operation on the remote operation device side, and has a function of canceling the firmware update (521). When the user presses the release button (207) of the remote operation device (201) while this screen is displayed, the processing after the processing flow S502 of FIG. 5 is executed in the remote operation device. In the imaging device, when the connection of the remote operation device is established and the user input information is received from the remote operation device (S621) in the processing flow S619 in FIG. 6B, the process proceeds to FIG.

  In FIG. 7D, since communication with the remote operation device has been established and the correct firmware version has been acquired, the version of the remote operation device is displayed and the OK button (531) is selected. When the user presses the enter button (116), the screen transitions to FIG.

  FIG. 7E corresponds to the processing flow S627, and the firmware file name of the valid remote operation device stored in advance in the storage medium (120) of the imaging device is displayed on the screen, and one of them is displayed by the user. Is selected. When the user presses the enter button (116), the screen changes to FIG.

  FIG. 7F corresponds to the processing flow S630. When the OK button (551) is selected and the user presses the enter button (116), the processing after S633 is executed, and FIG. ). FIG. 7G displays the progress status of the firmware update, which corresponds to the processing flow S637, and updates the progress status until the transmission of the firmware data is completed. When the transmission of the firmware data is completed, the process transitions to FIG.

  FIG. 7 (h) indicates to the user that the transmission of firmware data has been completed. When the OK button (571) is selected and the enter button (116) is pressed, the process proceeds to FIG. 7 (a), and the firmware update of the remote operation device is completed. As described above, when there is no opportunity for establishing a communication connection on the imaging apparatus side, the firmware version information is not displayed until a state where communication is possible through operation of the accessory device. In addition, it is possible to prevent wrong information from being displayed to the user by acquiring and displaying the version information when communication is established.

[Example 2]
A case where the imaging device is Bluetooth Low Energy (trademark) central and the remote operation device is a peripheral will be described. When the imaging device is a central device, the imaging device scans an advertisement signal from the paired remote operation device at a timing corresponding to the processing flow S411 in FIG. On the other hand, the remote operation device, which is a peripheral device, returns from the hibernation state when a button operation is performed by the user, and transmits an advertisement signal at a timing corresponding to the processing flow S504 in FIG. That is, even if the role of Bluetooth Low Energy (trademark) is reversed, the establishment of communication is triggered by pressing the button of the remote operation device.

  Therefore, as in the first embodiment, the firmware version information is not displayed until communication is established through the operation of the accessory device, and the wrong information is displayed to the user by acquiring and displaying the version information when communication is established. Displaying can be prevented.
