  The present invention relates to an imaging apparatus and an imaging apparatus control method, and more particularly to a technique suitable for use in an imaging apparatus capable of wireless communication.

  In recent years, a technique for mounting a wireless communication function in an imaging apparatus and transmitting a captured image to another device by wireless communication is known. For example, in Patent Document 1, it is possible to transmit an image captured by the first imaging device to the second imaging device in real time by wireless communication, and always check the image on the display unit of the second imaging device. Technology is described. Japanese Patent Application Laid-Open No. 2004-228561 also describes a technique that can remotely control the first imaging device by a button operation on a touch panel mounted on the second imaging device.

Furthermore, a lens style camera that itself does not have a display unit is also known, assuming that the captured image is transmitted to another device. In lens style cameras, the mainstream style is to attach to a device such as a mobile terminal with a display, and the user must check the captured image of the lens style camera in real time on the display on the mobile terminal. Is possible.
In such a lens style camera, as shown in FIG. 2, it is conceivable that one lens style camera (digital camera A100 in FIG. 2) is reused by a plurality of portable terminals.

In the present embodiment, the operation mode of the digital camera A100 refers to two types of modes, an imaging mode and a playback mode, which will be described later.

  In the present embodiment, the smartphone B100 includes an application (hereinafter referred to as an application) for the user to connect to and operate the digital camera A100, including switching of the operation mode. The application corresponds to a software program for processing in the control unit B101 of the smartphone B100, and the processing flow will be described later with reference to FIG.

  FIG. 2 is a conceptual diagram illustrating a communication relationship by wireless communication when the digital camera A100, the smartphone B100, and the smartphone C100 communicate with each other in a one-to-many relationship.

Further, after that, the case where the wireless communication is canceled and the digital camera A100 and the smartphone B100 are connected again in the reproduction mode will be described as an example.

  FIG. 3A is a conceptual diagram showing a captured image 303 for EVF (Electronic View Finder) displayed on the display unit 302 when the smartphone B100 is connected to the digital camera A100 in the imaging mode. In the present embodiment, the user gives an imaging instruction through an operation by the operation unit 301. The imaging instruction may be realized, for example, by a user operation using the touch panel of the display unit 302.

  FIG. 3B is a conceptual diagram showing a display screen of the smartphone B100 in the playback mode. As shown in FIG. 3B, the image 313 recorded in the imaging mode is displayed on the display unit 312 in a thumbnail format. By individually selecting the images 313, the selected images can be displayed in an enlarged manner on the display unit 312.

FIG. 4B is a conceptual diagram showing a display screen of the smartphone C100 in the playback mode. As shown in FIG. 4B, the image 413 recorded in the imaging mode is displayed on the display unit 412 in a thumbnail format.

  FIG. 5A is a conceptual diagram showing a Message display 504 that is displayed when the smartphone B100 is connected to the digital camera A100 again in the playback mode. This shows a display example when there is a difference between the media recording information held by the smartphone B100 and the media recording information held by the digital camera A100.

  Here, the media recording information refers to image management information recorded on the recording medium A110 of the digital camera A100. During operation of the digital camera A100, it is updated as file management information of the system and stored in the work memory A104. Is retained. Similarly, the recording medium B110 of the smartphone B100 has image management information.

  When the system is turned off when the power of the digital camera A100 is turned off, the file management information held in the work memory A104 is recorded in the secure memory A122 via the nonvolatile memory A103 and the sub control unit A121. .

  Similarly, the media recording information at the end of the system is also transmitted to the smartphone B100, and is recorded in the work memory B104 by the control unit B101 while the smartphone B100 is activated. When the power of the smartphone B100 is turned off, the media recording information recorded in the work memory B104 by the control unit B101 is a non-volatile functioning as a second recording information holding unit that holds the recording information of the digital camera A100. Is saved in the memory B103.

FIG. 5B is a conceptual diagram showing a display screen of the smartphone B100 when a new image is acquired from the digital camera A100.
In FIG. 5B, an image 513 is an image that has already been recorded in the smartphone B100, and an image 514 indicates an image that is newly acquired from the digital camera A100.

Hereinafter, each processing content is demonstrated about digital camera A100 and smart phone B100.
First, an outline of the operation mode selected on the application of the smartphone B100 will be described. In this embodiment, there are two types of operation modes, an imaging mode and a reproduction mode.

  The imaging mode is a mode in which an image is recorded by remotely operating the digital camera A100 with the smartphone B100. At this time, the power supply is supplied to the imaging reproduction unit A120 of the digital camera A100. In addition, the image captured by the imaging unit A102 is transferred to the smartphone B100 via the connection unit A111, and the EVF image is displayed on the smartphone B100 in real time. The user instructs the digital camera A100 to capture an image while displaying the EVF image on the smartphone B100.

  In addition, for example, an image recorded in the imaging mode is transmitted to the smartphone B100 by wireless communication via the connection unit A111 and recorded in the recording medium B110 of the smartphone B100 at the time of imaging recording. Thereby, even if it is not always connected with digital camera A100, it becomes possible to reproduce | regenerate a moving image by smart phone B100 single-piece | unit.

  The playback mode is a mode in which a recorded image is displayed on the smartphone B100 by processing of the sub-control unit A121 of the digital camera A100 described later and processing of the control unit A101.

Details of the playback mode will be described below.
In the playback mode, first, with the digital camera A100 turned off and the playback mode selected on the app of the smartphone B100, the smartphone B100 is brought close to the digital camera A100 to establish a short-range wireless communication connection. The smartphone B100 acquires the media recording information held in the secure memory A122 of the digital camera A100 by a read request command for short-range wireless communication.

  The smartphone B100 compares the acquired media recording information with the previously stored media recording information (media recording information acquired as the last history when connected to the digital camera A100 last time). If there is a difference in the media recording information, a message indicating that the recorded image is updated is displayed on the display unit B106 as a message. At the same time, a selection screen is displayed on the display unit B106 to determine whether or not to obtain an updated image recorded in the digital camera A100, thereby prompting the user to select.

Here, when the user instructs acquisition of an updated image, the smartphone B100 transmits an activation command to the sub-control unit A121 that performs activation mode determination processing of the digital camera A100 through short-range wireless communication.
The activation command is considered to be embedded as command information in short-range wireless communication and instructed to activate. Alternatively, for example, a case where an access space that is larger than the storage capacity of the secure memory A122 of the digital camera A100 is accessed via short-range wireless communication may be determined as an activation command.

  The sub-control unit A121 of the digital camera A100 receives the activation command, thereby powering on the imaging / playback unit A120 via the power-on unit A123, and wireless communication at the connection unit A111 according to the processing flow of the control unit A101 described later. Establish. Thereafter, the sub control unit A121 transfers the updated image to the smartphone B100 via the connection unit A111.

When the media recording information acquired from the secure memory A122 matches the media recording information held by the smartphone B100, a message indicating that the recorded image is not updated is displayed on the display unit B106, and the digital camera A100 It does not start.
As described above, in this embodiment, a state in which the update information of the recorded image in the digital camera A100 is confirmed and the image recorded on the smartphone B100 can be browsed and displayed is set as a reproduction mode.

Next, a processing flow in the sub control unit A121 of the digital camera A100 in this embodiment will be described with reference to FIG.
In FIG. 6, S600 indicates the start of this processing flow, and is a state in which the digital camera A100 and the smartphone B100 are close to a distance where short-range wireless communication is possible.

  Here, the distance at which near field communication is possible will be described. As described above, in this embodiment, the digital camera A100 behaves as Target and the smartphone B100 behaves as an initiator. Therefore, at the time of short-range wireless communication, a polling command is first transmitted from the smartphone B100. By this Polling command, the antenna of the short-range wireless communication unit A112 of the digital camera A100 acquires power by electromagnetic induction and receives a signal. As described above, the distance at which the smartphone B100 and the digital camera A100 can transmit and receive signals by electromagnetic induction is the distance at which short-range wireless communication is possible.

The sub-control unit A121 proceeds from S600 to S601 based on a change in current flowing through the antenna of the short-range wireless communication unit A112.
In S601, the sub control unit A121 transmits a response signal of the Polling command transmitted from the smartphone B100. The Polling command issued from the smartphone B100 refers to a command that requests (requests) a response command from the Target side in order to specify one communication partner such as SDD (Single Device Detection), for example.

In S601, a short-range wireless communication with the smartphone B100 is established by transmitting a response signal to the Polling command.
Next, in S602, the sub-control unit A121 receives a command indicating a connection mode in short-range wireless communication from the smartphone B100 via the short-range wireless communication unit A112.

  Next, in S603, the sub-control unit A121 determines whether the connection is in the P2P mode or the card reader mode from the command received in S602. If the sub-control unit A121 determines that the connection is in the card reader mode from the received command, the sub-control unit A121 reads the media recording information recorded in the secure memory A122 in S604.

In step S605, the sub control unit A121 transmits the read media recording information to the smartphone B100 via the short-range wireless communication unit A112.
Thereafter, the process proceeds to S606, which is the end state of this processing flow. In this processing flow, the end state refers to a state of waiting for a new command to be received by near field communication.

In S603, if the sub-control unit A121 determines that the P2P mode is obtained from the received command, in S607, the sub-control unit A121 issues a power-on command to the power-on unit A123, and the power supply of the imaging / playback unit A120 Insert. Here, after the imaging reproduction unit A120 is powered on, the processing control of the digital camera A100 shifts to the control unit A101. The processing flow of the control unit A101 will be described later with reference to FIG.
After S607, the process proceeds to S606, which is the end state of this processing flow.

Next, a processing flow in the control unit A101 of the digital camera A100 in this embodiment will be described with reference to FIG.
7, S700 indicates the start of this processing flow. In the processing flow of FIG. 6 described above, the processing control of the digital camera A100 is shifted from the sub control unit A121 to the control unit A101 in S607.

  Next, in step S701, the control unit A101 performs wireless communication that can perform long-distance communication at a higher speed than short-distance wireless communication via the connection unit A111 (hereinafter, long-distance wireless communication in order to be distinguished from short-distance wireless communication). Is established with the smartphone B100 via the connection unit B111. Here, in S701, for example, the control unit A101 may transmit and receive an SSID (Service Set Identifier) and an encryption key necessary for establishing long-distance wireless communication using the P2P mode of short-range wireless communication. It is done.

In step S <b> 702, the control unit A <b> 101 receives camera operation mode information from the smartphone B <b> 100 using the P2P mode of short-range wireless communication, and determines whether the received operation mode is a playback mode or an imaging mode.
If it is determined in S702 that the playback mode is selected, in S703, since the digital camera A100 is activated as the playback mode, the control unit A101 reads the media recording information from the secure memory A122 when the system is activated.

  In step S <b> 704, the control unit A <b> 101 compares the read media recording information with the file management information at the time of the previous system termination recorded in the nonvolatile memory A <b> 103 and determines whether there is an update. When the system is activated, the file management information is treated as the initial information of the nonvolatile memory A103.

  In the present embodiment, the processing flow in which the media recording information in the secure memory A122 is overwritten and updated from the smartphone B100, for example, will not be described, but details will be described later in the second embodiment.

If the control unit A101 determines in S704 that the media recording information is updated, the media recording information recorded in the secure memory A122 is updated as file management information by the control unit A101 in S705.
In step S <b> 706, the control unit A <b> 101 determines whether an update image transmission request command has been received from the smartphone B <b> 100 by long-distance wireless communication.

  Here, the update image will be described. For example, as shown in FIG. 5A described above, consider a case where there is a difference between the media recording information held by the smartphone B100 and the media recording information recorded in the secure memory A122 of the digital camera A100. In this case, an image recorded as a difference in the digital camera A100 (for example, the image 514 shown in FIG. 5B) is set as an updated image.

If the control unit A101 determines in S706 that the update image transmission request command has been received, the process proceeds to S707, and the update image is transmitted to the smartphone B100 via the long-distance wireless communication.
Next, in step S708, the control unit A101 causes the digital camera A100 to operate as a playback mode in which an image stored in the recording medium A110 can be displayed and edited by an application operation of the smartphone B100.

  In step S <b> 709, the control unit A <b> 101 determines whether the user has performed a power OFF operation in the state of the power button of the operation unit A <b> 105, for example. When the control unit A101 does not recognize the user's power-off operation, the process proceeds to S706, and the reproduction mode is maintained by repeatedly executing S706 to S709.

In S709, when the control unit A101 recognizes the user's power-off operation, the power of the digital camera A100 is turned off, and the process proceeds to S710, which is the end state of this processing flow.
If the control unit A101 determines in S706 that it has not received an update image transmission request command, the process proceeds to S708 described above and operates as a playback mode.
In S704, when the control unit A101 determines that the media recording information is not updated, the process proceeds to S706, and the playback mode is maintained by repeatedly executing S706 to S709.

Next, a case where the camera operation mode information received from the smartphone B100 is the imaging mode in S702 will be described.
In the case of the imaging mode, the process proceeds to S712.
In S712, the digital camera A100 is activated as an imaging mode by the control unit A101. Here, starting as the imaging mode means that, for example, the above-described optical lens unit retracted in the housing of the digital camera A100 is extended and acquired as an imaging standby state in order to acquire a captured image from the imaging unit A102. Means.

Next, in S713, the captured image for EVF is transferred to the smartphone B100 by the long-distance wireless communication via the connection unit A111 by the control unit A101.
As described above, while the smartphone B100 displays the acquired EVF capture image on the display unit B106, the user performs imaging with the digital camera A100 through an application operation of the smartphone B100.

  In S <b> 714, the digital camera A <b> 100 acquires a captured image from the imaging unit A <b> 102 at an arbitrary timing designated by the user by the application operation of the smartphone B <b> 100 by the control unit A <b> 101. Then, it operates as an imaging mode for recording on the recording medium A110.

Next, in S715, the control unit A101 determines whether the user has performed a power-off operation in the state of the power button of the operation unit A105, for example. When the control unit A101 does not recognize the user's power-off operation, the process proceeds to S713, and the captured image is repeatedly transmitted to the smartphone B100. Next, in S714, the imaging mode operation is maintained.
In S715, when the control unit A101 recognizes the user's power-off operation, the power of the digital camera A100 is turned off, and the process proceeds to S710, which is the end state of this processing flow.

Next, a processing flow in the control unit B101 of the smartphone B100 in this embodiment will be described with reference to FIG.
In FIG. 8, S800 indicates the start of this processing flow, and in the smartphone B100, the control unit B101 starts a state where an application for remotely operating the digital camera A100 in the present embodiment is activated.

In step S <b> 801, the control unit B <b> 101 sets the operation mode of the digital camera A <b> 100 as the operation mode selected by the user using the activated application.
In step S802, the control unit B101 determines whether the operation mode selected in step S801 is an imaging mode or a playback mode.

  In the reproduction mode, in step S803, the control unit B101 transmits a polling command from the short-range wireless communication unit B112. Although not shown in this processing flow, the Polling command is repeatedly transmitted until a response is returned from the digital camera A100 serving as a target, for example.

  If there is no response from the digital camera A100 for a certain period of time, a message indicating a connection error may be displayed on the display unit B106 to interrupt the connection. In the description of this embodiment, the processing flow will be described by taking as an example the case where a response of the Polling command is returned from the digital camera A100 in S803.

In step S804, the control unit B101 transmits a read request command from the short-range wireless communication unit B112. In step S804, the digital camera A100 is requested to respond in the card reader mode in the NFC standard.
In step S805, the control unit B101 receives media recording information recorded in the secure memory A122 from the digital camera A100 via the short-range wireless communication unit B112. The processing on the digital camera A100 side is executed in accordance with the processing flow of the sub-control unit A121 of FIG.

  In step S806, the control unit B101 compares the media recording information recorded in the nonvolatile memory B103 or the working memory B104 described above with the media recording information received in step S805, and determines whether there is a difference. Is determined. Here, the media recording information recorded in advance in the nonvolatile memory B103 or the working memory B104 indicates a final history when the digital camera A100 has been connected to the previous recording.

  Therefore, when the connection relationship is newly established, the recording image when the digital camera A100 captures an image with another portable terminal different from the smartphone B100 by receiving the media recording information of the digital camera A100. Can be determined.

In S806, when the control unit B101 determines that there is a difference between the media recording information held by the digital camera A100 and the media recording information held by the smartphone B100, the process proceeds to S807.
If the control unit B101 determines in S806 that there is no difference between the two pieces of media recording information, the process proceeds to S812 described below.
In S807, the control unit B101 displays a message on the display unit B106 that the image information of the digital camera A100 is updated. FIG. 5A described above shows a display screen at that time.

In step S808, the control unit B101 displays, for example, an instruction button on whether to acquire an updated image on the display unit B106, and prompts the user to select. When the control unit B101 determines that the user has selected acquisition of an updated image, the process proceeds to S809.
If the control unit B101 determines in step S808 that the user has not selected acquisition of an updated image, the process proceeds to step S812 described below.
In step S809, the control unit B101 transmits a command for requesting connection establishment in the P2P mode to the digital camera A100 via the short-range wireless communication unit B112.

  Here, although explanation is omitted in this processing flow, in step S809, in order to establish a new near field communication with the digital camera A100, transmission of a polling command and reception of a response are newly executed in the same manner as in step S803. It is possible.

  In step S809, after establishing the connection in the P2P mode, the control unit B101 transmits an update image transmission request command in step S810. Here, the update image transmission request command is the same as that used in S706 in the processing flow of the control unit A101 described with reference to FIG.

  In S809, a command for requesting connection establishment in the P2P mode is transmitted from the smartphone B100 via the short-range wireless communication unit B112. Thereby, establishment of the long-distance wireless communication of S701 in the processing flow of the control unit A101 of FIG. 7 is performed. Although not shown in this processing flow, it is assumed that far-distance wireless communication using the connection unit A111 and the connection unit B111 has already been established between the digital camera A100 and the smartphone B100 at the stage of exiting S810.

  Next, in step S811, the control unit B101 receives an update image from the digital camera A100 through long-distance wireless communication, and records the update image in the recording medium B110. Here, it is conceivable that the media recording information recorded in the working memory B104 is overwritten and updated with the information received in S805.

  In step S812, the control unit B101 displays the recorded image on the display unit B106 including the updated image newly received in the playback mode. FIG. 5B is a diagram showing a display screen at that time. Here, in step S811, when the update image has been acquired, the long-distance wireless communication connection may be disconnected and the digital camera A100 may be turned off.

In step S813, the control unit B101 determines, for example, whether the application end button on the GUI displayed on the display unit B106 has been pressed by detecting the button state.
If the control unit B101 determines in step S813 that the user has performed an application end operation, the process proceeds to step S814, which is the end state of this processing flow.
If the control unit B101 does not determine in step S813 that the user has performed an application termination operation, the process proceeds to step S812, and the playback mode is maintained.

A case will be described in which the operation mode selected in S801 is the imaging mode in S802.
In the imaging mode, in S815, the same processing as that in S803 is performed, and a polling command is transmitted from the short-range wireless communication unit B112 by the control unit B101. Then, after the response of the Polling command is returned from the digital camera A100, the process proceeds to S816.
In step S816, the control unit B101 transmits a command requesting connection in the P2P mode from the short-range wireless communication unit B112, and establishes a connection with the digital camera A100.

  Next, in S817, the EVF capture image transferred from the digital camera A100 in S713 is received in the processing flow of the control unit A101 in FIG. The received image is temporarily recorded in the work memory B104 by the control unit B101.

  Next, in S818, the control unit B101 causes the smartphone B100 to perform a camera imaging operation. As described above, the imaging operation means that the user gives an imaging instruction with the digital camera A100 by an application operation of the smartphone B100 while displaying the captured image for EVF recorded in the work memory B104 on the display unit B106. means.

Next, in S819, the control unit B101 determines, for example, whether the application end button on the GUI displayed on the display unit B106 has been pressed by detecting the button state.
If the control unit B101 determines in S819 that the user has performed an application termination operation, the process proceeds to S814, which is the termination state of this processing flow.

If the control unit B101 does not determine in step S819 that the user has performed the application termination operation, the process proceeds to step S817, and the capture image is received and the imaging operation is maintained in the next step S818. .
As described above, according to the configuration of the present embodiment, the digital camera A100 can be operated on the application of the smartphone B100 according to the operation mode, and unnecessary power-on can be prevented, and image capturing and reproduction can be operated by remote operation by wireless communication. It becomes possible.

Here, the recording image sharing setting in the present embodiment will be described.
As described above, when a plurality of smartphones connect to a single digital camera at different times and capture images, they are recorded and updated as sharable images on a recording medium in the digital camera.

However, some users may not want to share personal images. Therefore, a procedure for canceling the sharing setting of the captured image will be described.
First, as an example, a case where the digital camera A100, the smartphone B100, and the smartphone C100 in FIG.

First, the digital camera A100 and the smartphone B100 are in a connection relationship and take an image.
Next, after the connection with the smartphone B100 is released, the digital camera A100 and the smartphone C100 are connected to take an image. Thereafter, after the connection with the smartphone C100 is released, the digital camera A100 and the smartphone B100 are reconnected.
FIG. 3B is a conceptual diagram in which an image 313 first captured by the smartphone B100 connected to the digital camera A100 is displayed on the display screen.

  FIG. 9 is a conceptual diagram of a display screen when an image to be released from sharing setting is selected by an operation on the touch panel for an image 903 captured by the smartphone C100 connected to the digital camera A100. The image sharing setting is added to the above-described media recording information of the digital camera A100. For example, it is conceivable that the individual information of the mobile terminal is attached to the image information of the image whose sharing setting is canceled.

As described above, when the sharing setting of the image captured by the smartphone C100 is canceled, when the smartphone B100 is reconnected, only the difference information of the shared image is compared. Therefore, in S806 in FIG. The difference is not detected. Therefore, when the smartphone B100 is reconnected, the screen of FIG. 3B is displayed as in the previous connection.
As described above, according to the configuration of the present embodiment, the individual information addition process for adding the individual information of the smartphone to the image at the time of shooting is performed, and the image browsing authority setting process for setting the image browsing authority is performed based on the individual information. . Then, it is possible to determine whether or not there is an update only for an image having a viewing authority (shared image), thereby preventing unnecessary power-on.

[Second Embodiment]
In 1st Embodiment, the operation mode set when operating digital camera A100 from the application of smart phone B100 demonstrated and demonstrated the case of two types, imaging mode and reproduction | regeneration mode, as an example.
On the other hand, in the present embodiment, a case where there are three types of operation modes of a recorded image update mode in addition to the imaging mode and the playback mode will be described.
Since this embodiment has many parts in common with the first embodiment, the explanation will focus on the parts specific to this embodiment, and the same reference numerals will be used for the portions showing the same contents as in FIG. Omitted.

  In the present embodiment, the smartphone B100 can change the operation mode of the digital camera A100 under the control of the control unit B101 described later. Here, the operation mode of the digital camera A100 refers to three types of modes: an imaging mode, a playback mode, and a recorded image update mode.

  In the present embodiment, the smartphone B100 includes an application for the user to connect to and operate the digital camera A100, including switching of operation modes. The application corresponds to a software program for processing in the control unit B101 of the smartphone B100, and the processing flow will be described later with reference to FIG.

Hereinafter, each processing content is demonstrated about digital camera A100 and smart phone B100.
First, an outline of the operation mode on the application of the smartphone B100 will be described. Since the imaging mode and the playback mode are the same as those described in the first embodiment, description thereof is omitted.

The recorded image update mode operates as follows.
FIG. 10A is a conceptual diagram when a recorded image is displayed on the display screen of the smartphone B100. At this time, the smartphone B100 and the digital camera A100 are not connected.

An image 1003 and an image 1004 in FIG. 10A are images taken when the smartphone B100 is connected to the digital camera A100. The image 1004 shows a display screen of the smartphone B100 when the user selects an image as a deletion target.
FIG. 10B is a display screen of the smartphone B100 after the user has decided to delete the image 1004.

At this time, the media recording information of the smartphone B100 is updated.
Thereafter, the media recording information of the smartphone B100 is reflected in the media recording information of the digital camera A100. For this purpose, the media record information held in the secure memory A122 of the digital camera A100 is updated by the card writer mode for short-range wireless communication.

The updated media recording information in the secure memory A122 is merged with the media recording information held in the non-volatile memory A103 when the imaging playback unit A120 is powered on and activated by the processing of the control unit A101. The Thereby, the file management information used in the system is updated.
Further, based on the file management information of the system updated at the time of activation, the control unit A101 also updates the above-described image management information of the recording medium A110.

Hereinafter, details of the processing flow of each control unit will be described.
A processing flow in the sub control unit A121 of the digital camera A100 according to the present embodiment will be described with reference to FIG.
In FIG. 11, steps S1100 to S1102 are the same as steps S600 to S602 of FIG.

In S1103, the same process as S603 in FIG. 6 is performed. If the received command is in the P2P mode, the same process as S607 in FIG.
If it is determined in S1103 that the mode is not the P2P mode, in S1104, the sub-control unit A121 determines whether or not the received command is a connection in the card writer mode.

If the card writer mode is not determined, the card reader mode is set and the process proceeds to S1108.
In S1108 to S1109, the same processing as S604 to S605 in FIG.

If the sub control unit A121 determines in the card writer mode in S1104, the sub control unit A121 overwrites the media recording information in the secure memory A122 based on the command information received from the smartphone B100 in S1105.
In step S1106, the sub control unit A121 transmits a write completion response signal to the smartphone B100 via the short-range wireless communication unit A112.
Thereafter, the process proceeds to S1107, and this processing flow ends.

  In the present embodiment, the processing flow of the control unit A101 has the same configuration as that of FIG. 7 described in the first embodiment. Therefore, in the following description of the present embodiment, the same reference numerals are used to indicate the same contents. The description is omitted.

Next, a processing flow in the control unit B101 of the smartphone B100 in this embodiment will be described with reference to FIG.
In FIG. 12, S1200 to S1202 are the same as S800 to S802 of FIG. If the control unit B101 determines in S1202 that the imaging mode is selected, the processing of S1216 to S1220 is performed, but the same processing as S815 to S819 of FIG. .

If the control unit B101 determines in S1202 that the mode is not the imaging mode, it determines in S1203 whether the control unit B101 is the playback mode or the recorded image update mode.
Here, in S1203, when the control unit B101 determines the playback mode, the process proceeds to S1204.
In S1204 to S1214, the same processing as S803 to S813 in FIG.

If the control unit B101 determines in the recording image update mode in S1203, the process proceeds to S1221.
In S1221, the control unit B101 displays the image information that the smartphone B100 already has on the display unit B106. As a result, the user can edit the image information such as deleting and editing the image through the GUI. Here, when the image is deleted or edited by the user, the media recording information of the smartphone B100 is overwritten and updated. In addition, based on the overwritten media recording information, the image management information held by the recording medium B110 is also updated by the control unit B101.

Next, in S1222, the control unit B101 determines, for example, whether or not the user has performed a button operation for overwriting and transmitting the media recording information to the digital camera A100 displayed on the display unit B106.
If the button operation for overwriting transmission is not executed in S1222, the process proceeds to S1226 described later.

  If a button operation for overwriting transmission is executed in S1222, a polling command is transmitted from the short-range wireless communication unit B112 by the control unit B101 in S1223. The detailed processing content is the same as that of S803 in FIG.

Next, in S1224, the control unit B101 transmits a write request command from the short-range wireless communication unit B112. Here, in S1224, the digital camera A100 is requested to respond in the card writer mode in the NFC standard.
Next, in S1225, the control unit B101 transmits the media recording information to the digital camera A100 via the short-range wireless communication unit B112.
Here, for explanation, S1224 and S1225 are written separately, but in S1224, the media recording information may be added to the write request command and transmitted.

Next, in step S1226, the control unit B101 determines, for example, whether the application end button on the GUI displayed on the display unit B106 has been pressed by detecting the state of the button.
If the control unit B101 determines in step S1226 that the user has performed an application end operation, the process proceeds to step S1215, which is the end state of this processing flow.
If the control unit B101 does not determine in step S1226 that the user has performed an application termination operation, the process proceeds to step S1221, and the recorded image update mode is maintained.

As described above, it is possible to transmit the updated media recording information to the digital camera A100 on the application of the smartphone B100 and overwrite the media recording information held by the digital camera A100. As a result, in the recorded image update mode, the image can be deleted and edited only by the smartphone B100. In addition, when overwriting the media recording information of the digital camera A100, the power consumption of the digital camera A100 is reduced because it is executed only by short-range wireless communication without turning on the imaging reproduction unit A120.
According to the embodiment of the present invention, it is possible to delete and edit the recorded image in the camera without starting up the camera by overwriting the image recording information of the camera by short-range wireless communication.

[Third Embodiment]
In 1st and 2nd embodiment, the case where the difference comparison of media recording information was implemented with smart phone B100 was demonstrated.
In contrast, in the present embodiment, a case where the sub-control unit A121 of the digital camera A100 performs a difference comparison of media recording information will be described.
Since this embodiment has many parts in common with the first embodiment, the explanation will focus on the parts specific to this embodiment, and the same reference numerals will be used for the portions showing the same contents as in FIG. Omitted.

In the present embodiment, as in the second embodiment, the smartphone B100 can select three types of operation modes: an imaging mode, a playback mode, and a recorded image update mode.
Also in the present embodiment, the smartphone B100 includes an application for the user to connect to and operate the digital camera A100, including switching of the operation mode. The application corresponds to a software program for processing in the control unit B101 of the smartphone B100, and the processing flow will be described later with reference to FIG.

Hereinafter, each processing content is demonstrated about digital camera A100 and smart phone B100.
A processing flow in the sub control unit A121 of the digital camera A100 in the present embodiment will be described with reference to FIG.
In FIG. 13, steps S1300 to S1302 are the same as steps S600 to S602 of FIG.
In S1303, the same process as S603 in FIG. 6 is performed, and when the received command is in the P2P mode, the process proceeds to S1313. In the case of the P2P mode, step 1313 is executed, but the same processing as S607 in FIG.

If the sub control unit A121 determines in S1303 that the received command is not in the P2P mode, in S1304, the sub control unit A121 determines whether or not the received command is a command in the card writer mode.
If it is determined in S1304 that the card writer mode is set, the process proceeds to S1305. Steps S1305 to S1306 are the same as steps S1105 to S1106 in FIG.

  If the card writer mode is not determined in S1304, the sub-control unit A121 extracts the media recording information of the smartphone B100 from the received command in S1308.

In step S1309, the sub control unit A121 reads the media recording information of the digital camera A100 from the secure memory A122.
Next, in S1310, the sub-control unit A121 performs recording information comparison processing for comparing the media recording information of the smartphone B100 and the media recording information of the digital camera A100.

If it is determined in S1310 that there is a difference between the two pieces of media recording information, in S1311, the sub-control unit A121 converts the media recording information as a response signal in the card reader mode via the short-range wireless communication B112. Send that there is no difference. For example, flag information (for example, 0 is set for matching and 1 is set for mismatching) is embedded in the response command and transmitted.
Thereafter, the process proceeds to S1307, which is the end state of this processing flow.

If the sub control unit A121 determines in S1310 that there is a difference between the media recording information of the smartphone B100 and the media recording information of the digital camera A100, the process proceeds to S1312.
In S1312, the sub-control unit A121 transmits a message indicating that there is a difference in the media recording information as a response signal in the card reader mode via the short-range wireless communication B112. For example, it is embedded in a response command as flag information and transmitted.
Thereafter, the process proceeds to S1307, which is the end state of this processing flow.

  In the present embodiment, the processing flow of the control unit A101 has the same configuration as that of FIG. 7 described in the first embodiment. Therefore, the same reference numerals are used in the following description of the present embodiment to indicate the same contents. The description is omitted.

Next, a processing flow in the control unit B101 of the smartphone B100 in this embodiment will be described with reference to FIG.
14, steps S1400 to S1402 are the same as the steps S800 to S802 in FIG. If the control unit B101 determines in S1402 that the imaging mode is selected, the processing of S1416 to S1420 is performed, but the same processing as S815 to S819 of FIG. .

If the control unit B101 determines in S1402 that the current mode is not the imaging mode, in S1403, the same processing as in S1203 in FIG. 12 is executed to determine whether the control unit B101 is in the playback mode or the recorded image update mode.
If the control unit B101 determines in the recording image update mode in S1403, the process proceeds to S1421.

In S1421 to S1426, the same processing as S1221 to S1226 in FIG.
If the control unit B101 determines in S1403 that the playback mode is set, the same processing as S803 in FIG. 8 is executed in S1404, and thus the description thereof is omitted.
Next, in S1405, the media recording information of the smartphone B100 is added to the read request command and transmitted by the control unit B101.

  In step S1406, the control unit B101 receives the comparison result of the media recording information from the digital camera A100 via the short-range wireless communication unit B112. Here, the comparison result of the media recording information is flag information added to the response signal of the digital camera A100 described in S1311 and S1312 in FIG. Further, it is conceivable that an SSID and an encryption key necessary for establishing a long-distance wireless communication, which will be described later, are received as additional information in the response signal.

In step S <b> 1407, the control unit B <b> 101 determines whether there is a difference in the media recording information between the digital camera A <b> 100 and the smartphone B <b> 100 using the comparison result of the received media recording information.
In S1407, for example, when the above-described flag information is 0 (comparison result is coincident), the process proceeds to S1413 described later.

In S1407, for example, if the flag information is 1 (comparison result does not match), the process proceeds to S1408.
In S1408, the control unit B101 displays a message on the display unit B106 that the media recording information has a difference between the digital camera A100 and the smartphone B100.

Next, in S1409, processing similar to that in S808 of FIG. 8 is executed, and a selection instruction as to whether or not to obtain an updated image from the digital camera A100 is prompted.
In S1409, when the control unit B101 does not determine that the user has selected acquisition of an updated image, the process proceeds to S1413 described below.

  If the control unit B101 determines in S1409 that the user has selected acquisition of an updated image, the process proceeds to S1410. In step S1410, the control unit B101 establishes a long-distance wireless communication connection with the digital camera A100 via the connection unit B111 based on the SSID and encryption key received in step S1406.

After that, in step S1411, the control unit B101 transmits an update image transmission request command via the connection unit B111.
Next, in S1412, the update image is received via the connection unit B111. However, in S1412 to S1415, the same processing as S811 to S814 in FIG.

  As described above, in this embodiment, the sub-control unit A121 performs a difference comparison between the media recording information of the smartphone B100 and the media recording information of the digital camera A100. As a result, the sub-control unit A121 can turn on the power of the imaging reproduction unit A120 based on the comparison result.

  Here, in the first embodiment, the media recording information is compared on the smartphone B100 side. Therefore, short distance wireless communication is established once by the act of reading the media recording information from the digital camera A100. Furthermore, when there is a difference in the comparison results of the media recording information, it is necessary to establish short-range wireless communication again in order to establish a long-range wireless communication connection via the P2P mode.

  However, in this embodiment, since the media recording information is compared on the digital camera side, the connection of the long-distance wireless communication is automatically established when there is a difference in the media recording information by establishing the short-range wireless communication once. It becomes possible to do.
