Description

  The present invention relates to a technique in which an image data transmitting apparatus publishes an image to an information processing apparatus.

  In recent years, digital functions and digital video cameras (hereinafter simply referred to as cameras) have been equipped with wireless functions. For example, a camera can be connected to a mobile phone by a wireless connection method such as a wireless communication method (wireless LAN) of a LAN system typified by a communication method of the IEEE802.11 series or BlueTooth (registered trademark). As a result, it is possible to view and select image data captured by the camera, transmit the image data to a mobile phone, view the downloaded image on the mobile phone, and upload it to an image sharing site.

Here, as a use case, when a camera and a mobile phone are connected wirelessly and an image in the camera is browsed, a case where a photograph is easily distributed to a person who was at the shooting site can be considered. However, a situation occurs in which it is not desired to show an image other than the image taken when the user is together.
Therefore, using the camera's disclosure restriction function, it was possible to switch between settings such as “Images from today to how many days ago”, “Select by rating”, “File number range”, or by selecting an image. It may be possible to control the disclosure / non-disclosure of images.
Consider a case in which, for example, only an image that was captured when a camera was set up with an acquaintance at a party venue in an image stored in the user's digital camera with the public setting of the camera would be disclosed to the acquaintance's mobile phone. In this case, there is a problem that it takes time and effort to set whether to disclose each image. In addition, with a uniform public restriction setting that only shows images taken today, unintended private photos such as images that you do not want to publish when you are not with an acquaintance in today can be released There is sex.

Patent Document 1 discloses that a digital camera receives device information from another device within a communication range, captures an image, and then adds the received device information to the captured image. . When there is an image acquisition request from another device, the digital camera refers to whether the requested device information is added to the requested image, and if it is added, permits acquisition. It is disclosed.
Further, in Patent Document 2, in an imaging device, a request packet is transmitted to another communication terminal at the time of shooting, and the other communication terminal that has received the request packet captures a response packet indicating the presence of an image to be acquired later. Transmitting to a device is disclosed. Then, it is disclosed that the imaging device that has received the response packet stores the content, and the imaging device actually performs an image acquisition process based on the stored content of the response packet.

However, in the prior art, information on a detection device is given to captured image information, and it is determined whether the information can be downloaded based on the information (see Patent Document 1). There is a problem that unnecessary image information manipulation is performed on a captured image.
In addition, when the connection between the digital camera and the mobile phone is established, the digital camera and the mobile phone can communicate with each other, and a method for recording the detection period of the digital camera for the first time has been proposed. (See Patent Document 2). However, there is a troublesome problem such as connection setting processing and waiting for connection completion time when connecting the digital camera and the mobile phone.

  SUMMARY An advantage of some aspects of the invention is that an image recorded by an image data transmission apparatus can be disclosed to a specific information processing apparatus.

  The network system of the present invention is a network system in which an image data transmitting apparatus and an information processing apparatus communicate with each other, and either the image data transmitting apparatus or the information processing apparatus transmits device information, and the other is a device. Detecting the information, recording the information of the device information detection period, and for the image recorded by the image data transmitting apparatus, the image to be disclosed is determined according to the recording date of the image and the information of the device information detection period. A selection means for selecting is provided.

  According to the present invention, it is possible to publish only an image taken when an image data transmission device is recorded with an acquaintance, without taking time, to the information processing device of the acquaintance.

[First Embodiment]
<Configuration of digital camera>
A digital camera 100 that is an example of an image data transmission device will be described.
FIG. 1 is a block diagram illustrating a configuration of a digital camera 100 according to the first embodiment.
The control unit 101 controls each unit of the digital camera 100 according to an input signal and a program described later. Note that instead of the control unit 101 controlling the entire apparatus, a plurality of hardware may share the processing to control the entire apparatus.

The imaging unit 102 converts subject light imaged by the lens into an electrical signal, and outputs digital data subjected to noise reduction processing or the like as image data. The captured image data is stored in the buffer memory, and then a predetermined calculation is performed by the control unit 101 and recorded on the recording medium 110.
The nonvolatile memory 103 is an electrically erasable / recordable nonvolatile memory, and stores various programs executed by the control unit 101.
The work memory 104 is used as a buffer memory that temporarily holds image data picked up by the image pickup unit 102, an image display memory of the display unit 106, a work area of the control unit 101, and the like.

  The operation unit 105 is used to receive an instruction for the digital camera 100 from a user. The operation unit 105 includes operation members such as a power button for instructing the user to turn on / off the digital camera 100, a release switch for instructing photographing, and a reproduction button for instructing reproduction of image data. A touch panel formed on the display unit 106 is also included in the operation unit 105. The release switch has SW1 and SW2. When the release switch is in a so-called half-pressed state, SW1 is turned on. As a result, an instruction for making preparations for shooting such as AF (autofocus) processing, AE (automatic exposure) processing, AWB (auto white balance) processing, and EF (flash pre-emission) processing is accepted. Further, when the release switch is in a fully-pressed state, SW2 is turned on. As a result, an instruction for photographing is received.

The display unit 106 displays a viewfinder image at the time of shooting, displays shot image data, displays characters for interactive operation, and the like. Note that the display unit 106 is not necessarily built in the digital camera 100. The digital camera 100 can be connected to an internal or external display unit 106 and only needs to have at least a display control function for controlling display on the display unit 106.

The imaging unit 202 converts subject light imaged by the lens into an electrical signal, and outputs digital data subjected to noise reduction processing or the like as image data. The captured image data is stored in the buffer memory, and then a predetermined calculation is performed by the control unit 201 and recorded on the recording medium 210.
The nonvolatile memory 203 is an electrically erasable / recordable nonvolatile memory, and stores various programs executed by the control unit 201. It is assumed that a program for communicating with the digital camera 100 is also stored in the nonvolatile memory 203 and installed as a camera communication application. The processing of the mobile phone 200 in this embodiment is realized by reading a program provided by a camera communication application. It is assumed that the camera communication application has a program for using the basic functions of the OS installed in the mobile phone 200. Further, the OS of the mobile phone 200 may have a program for realizing the processing in the present embodiment.
The work memory 204 is used as a buffer memory that temporarily stores image data picked up by the image pickup unit 202, an image display memory of the display unit 206, a work area of the control unit 201, and the like.

The operation unit 205 is used to receive an instruction for the mobile phone 200 from the user. The operation unit 205 includes an operation member such as a power button on which the user instructs to turn on / off the mobile phone 200 and a touch panel formed on the display unit 206, for example.
A display unit 206 displays image data, displays characters for interactive operation, and the like. Note that the display unit 206 is not necessarily built in the mobile phone 200. The mobile phone 200 can be connected to the internal or external display unit 206 and only needs to have at least a display control function for controlling the display of the display unit 206.
The recording medium 210 can record image data output from the imaging unit 202. The recording medium 210 may be configured to be detachable from the mobile phone 200 or may be built in the mobile phone 200. That is, the mobile phone 200 only needs to have at least a means for accessing the recording medium 210.

<Overview of network system for image publishing>
FIG. 3 is a diagram schematically illustrating a connection form between the digital camera 100 and the mobile phone 200 according to the first embodiment.
When the digital camera 100 and the mobile phone 200 transmit and receive data wirelessly, two connection forms shown in FIGS. 3A and 3B are conceivable as connection forms in the wireless LAN.

FIG. 3A shows a form in which the digital camera 100 and the mobile phone 200 participate in a wireless LAN network formed by the external AP 300 that is an external relay device. The digital camera 100 and the mobile phone 200 detect a beacon signal periodically transmitted by the external AP 300 and participate in a wireless LAN network formed by the external AP 300. After participating in the same wireless LAN network, the digital camera 100 and the mobile phone 200 are ready to transmit and receive data via the wireless LAN through mutual device discovery and device capability acquisition (establish communication between devices). .
Further, the external AP 300 in this embodiment can be connected to an external network such as the Internet using a public network or the like. Therefore, the mobile phone 200 can transmit data over the Internet via the external AP 300.

  FIG. 3B illustrates a form in which the digital camera 100 and the mobile phone 200 are directly connected without using the external AP 300. In this case, the digital camera 100 operates as a simple AP to form a wireless LAN network. When the digital camera 100 operates as a simple AP, the digital camera 100 starts to periodically transmit a beacon signal. The mobile phone 200 detects the beacon signal and participates in the wireless LAN network formed by the digital camera 100. Then, similarly to the case of FIG. 3A, communication is established through mutual device discovery, device capability acquisition, and the like, and a state in which data can be transmitted and received.

  Note that the digital camera 100 in this embodiment does not have a function of communicating with an external network such as the Internet. Therefore, the mobile phone 200 participating in the wireless LAN network formed by the digital camera 100 cannot transmit data to the Internet or the like via the simple AP.

  In connection processing between the digital camera 100 and the mobile phone 200 via BlueTooth, a beacon signal transmitted from the digital camera 100 called an advertisement signal is used. The mobile phone 200 detects the advertisement signal, identifies the digital camera 100, establishes a connection through the BlueTooth pairing process, and becomes ready for data transmission / reception. Contrary to the above, the digital camera 100 detects an advertisement signal transmitted from the mobile phone 200, identifies the mobile phone 200, establishes a connection through a BlueTooth pairing process, and can transmit and receive data. It becomes a state.

  As described above, there are three connection modes between the digital camera 100 and the mobile phone 200. In this embodiment, an example in which appropriate control is performed according to these connection modes will be described.

<Outline of the process of publishing images taken when you were together>
Processing for automatically publishing an image taken when the photographer is with an acquaintance from the digital camera 100 to an acquaintance's mobile phone will be described.
FIG. 4A is a diagram schematically showing that surrounding mobile phones are detecting device information transmitted from the digital camera 100. The device information indicates radio wave information transmitted from the own device so that a device that can be a connection target in the vicinity detects the own device when communication is not established. For example, in a wireless LAN, a beacon signal including SSID and MAC address information is used. In Bluetooth 4.0, an advertisement signal is used.
When the photographer 402 turns on the power of the digital camera 100, Bluetooth in the camera 100 becomes valid, and the digital camera 100 transmits an advertisement signal 401 that is device information.
The mobile phone around the digital camera 100, here, the mobile phone 200 of the acquaintance 403, is transmitted from the digital camera 100 in the state set to “Yes” on the image capture setting screen 502 shown in FIG. When device information is detected, the device information is recorded and saved as a log.

FIG. 4B shows a case where the device information is stored in the case as shown in FIG. 4A, and then the digital camera 100 and the mobile phone 200 of the acquaintance 403 are connected via a wireless LAN, and the photographer 402 is connected to the acquaintance 403. It is a figure which shows typically a mode that the image image | photographed when it existed together is shown to the mobile telephone 200 of the acquaintance 403. FIG.
The digital camera 100 connects the digital camera 100 and the mobile phone 200 via a wireless LAN in a state where “image when together” is set on the public image setting screen 501 shown in FIG. The digital camera 100 transmits a list of images to the mobile phone 200. The mobile phone 200 connected to the digital camera 100 can be made public by referring to the list of images acquired from the digital camera 100 and the setting of public images, and the detected log information (device information log) stored in the mobile phone 200. The correct image. The owner (acquaintance 403) of the mobile phone 200 selects the displayed image, transfers the selected image data from the digital camera 100 to the mobile phone 200, and saves it. As a result, only the image when it was together from the digital camera 100 can be released and stored in the mobile phone 200.

In the following, details of the process of publishing an image taken when they were together will be described.
<Device information transmission and detection processing>
First, the situation shown in FIG. 4A, that is, details of device information transmission and detection processing will be described.
FIG. 6A is a flowchart illustrating device information transmission processing of the digital camera 100 according to the first embodiment.
When the power of the digital camera 100 is turned on and the camera is ready for photographing, the control unit 101 activates Bluetooth in step S601, and the process proceeds to step S602.
In step S602, the control unit 101 transmits device information to the surroundings via the Bluetooth unit 215, and the process proceeds to step S603. FIG. 7A is a diagram illustrating an example of device information 701 transmitted from the digital camera 100 to the surrounding mobile phone 200. The device information 701 is information that is arbitrarily set by the photographer and includes a device name of the digital camera 100, a device type indicating a model format, and a device ID unique to the device such as a serial number.

In step S603, the control unit 101 determines whether the release switch has been pressed. If the release switch is pressed, the process proceeds to step S604. If the release switch is not pressed, the process proceeds to step S605.
In step S604, the control unit 101 starts photographing, records the photographed image data on the recording medium 110, and attaches the photographing date and time, the device type and device ID of the digital camera 100 that photographed at that time to the image data.
In step S605, it is determined whether the power of the digital camera 100 is turned off. If the power is turned off, the entire process is terminated. If the power is not turned off, the process returns to step S603.

FIG. 6B is a flowchart illustrating device information detection processing of the mobile phone 200 according to the first embodiment.
When the power of the mobile phone 200 is turned on and the activation of the operating system of the mobile phone 200 is completed, in step S611, the control unit 201 starts an application by a user operation, and moves the process to step S612.
In step S612, the control unit 201 activates Bluetooth and moves the process to step S613.

In step S613, the control unit 201 determines whether device information transmitted from the surrounding digital camera 100 has been detected. If device information is detected, the process proceeds to step S614, and if not detected, the process proceeds to step S617.
In step S614, the control unit 201 records and stores the detected device information in the recording medium 210 as a log. FIG. 7B is a diagram showing an example of log information 702 that the mobile phone 200 detects device information 701 transmitted from the digital camera 100 and records and saves it as a log. The log information 702 records a detection device name, a detection device type, a detection device ID, a detection start date / time, and a detection end date / time as one set based on the device information 701 detected by the mobile phone 200. Each time device information is newly detected, it is recorded as the second and subsequent sets.

In step S615, the control unit 201 determines whether the detected device information 701 cannot be detected. If device information cannot be detected, the process proceeds to step S616. If device information is detected, step S615 is repeated for a predetermined time.
In step S616, the control unit 201 records the detection end date and time in the log information 702, stops log recording, and moves the process to step S617. In this case, comparison is made with the previously recorded log information of the detection device. If the detection device name, detection device type, and detection device ID are the same and detection starts within a certain time (for example, 20 minutes) determined from the detection end date and time, communication is temporarily interrupted and log recording is interrupted It is treated as log information of the previously recorded detection device. In this case, the detection end time is changed when the detection of the device information ends. That is, when communication is temporarily interrupted, the device information detection periods before and after that are treated as a series of periods.
In step S617, the control unit 201 determines the end of the application due to a user operation or a stop command from the operating system. If the application is terminated, the process is terminated. If the application is not terminated, the process returns to step S613.

In the present embodiment, a series of flows from the start of device information detection to the end of detection is shown, but the processing may be performed in parallel by the multi-thread function of the operating system. Specifically, when device information of another digital camera different from the device being detected is detected, a series of processing from step S613 to step S616 may be performed in parallel.
FIGS. 6A and 6B show a flow of device information detection and log information storage of the digital camera 100 and the mobile phone 200, but this flow is a situation in which communication by a wireless LAN, BlueTooth, or the like has not been established. Done in

<Publishing and transferring images>
Next, details of the situation shown in FIG. 4B, that is, the process of connecting the digital camera 100 and the mobile phone 200 via a wireless LAN, publishing an image of the digital camera 100 to the mobile phone 200, and transferring it will be described.
FIG. 8A is a flowchart showing processing of the digital camera 100 when the digital camera 100 publishes an image to the mobile phone 200 and transfers image data in the first embodiment.
The digital camera 100 is turned on, the wireless LAN unit 111 is enabled, and the process starts with being able to connect to an external device.
In step S801, the control unit 101 establishes a wireless LAN connection with the mobile phone 200 in which the wireless LAN function is enabled, and the process proceeds to step S802.
In step S802, the control unit 101 transmits setting information of the digital camera 100 to the connected mobile phone 200 as initial communication. The setting information of the digital camera 100 includes “public image setting”. When the transmission of the setting information to the mobile phone 200 is completed, the process proceeds to step S803.

In step S803, the control unit 101 transmits a list of images stored in the recording medium 110 to the mobile phone 200, and the process proceeds to step S804.
In step S804, the control unit 101 determines whether there is an image acquisition request from the mobile phone 200 to the digital camera 100 by specifying an object handle. If there is an acquisition request, the process proceeds to step S805. If there is no acquisition request, the process proceeds to step S806.
In step S805, the control unit 101 transmits the image data designated from the mobile phone 200 to the mobile phone 200 via the wireless LAN unit 111, and the process proceeds to step S806.
In step S806, the control unit 101 determines whether the wireless LAN connection with the mobile phone 200 has been disconnected. If the wireless LAN connection is disconnected, the process is terminated. If the wireless LAN connection is not disconnected, the process returns to step S804.

FIG. 8B is a flowchart illustrating processing of the mobile phone 200 when an image is disclosed from the digital camera 100 to the mobile phone 200 and image data is transferred in the first embodiment.
The mobile phone 200 is turned on, the wireless LAN unit 211 is enabled, and the mobile phone 200 starts in a state where it can be connected to an external device.
In step S811, the control unit 201 activates an application program for the mobile phone 200 to instruct image display control by a user operation, and the process proceeds to step S812.
In step S812, the control unit 201 establishes a wireless LAN connection with the digital camera 100, and the process proceeds to step S813.
In step S813, the control unit 201 acquires setting information from the connected digital camera 100 as initial communication. The setting information of the digital camera 100 includes “public image setting”. When the reception of setting information from the digital camera 100 is completed, the process proceeds to step S814.

In step S814, the control unit 201 acquires a list of images stored in the digital camera 100 from the digital camera 100, and moves the process to step S815.
In step S <b> 815, the control unit 201 determines whether the “public image setting” acquired from the digital camera 100 is set to “image when together”. If it is set to “image when present together”, the process proceeds to step S816. If not set, an image is selected according to other settings, and the process proceeds to step S820.

In step S816, the control unit 201 determines whether the log information detected so far is stored. If log information has not been saved, the number of selected images is set to zero, and the process proceeds to step S820. If the device information log is stored, the process proceeds to step S817.
In step S817, the control unit 201 reads and expands the saved log information, and moves the process to step S818.
In step S818, the control unit 201 performs a matching process between the device detection period of the log information and the image information in the digital camera, and moves the process to step S819. Details of the matching process will be described later.
In step S819, the control unit 201 selects an image to be disclosed from the result of step S818, and moves the process to step S820.

In step S820, the control unit 201 displays a list of selected images on the display unit 206, and the process proceeds to step S821.
In step S <b> 821, the control unit 201 determines whether a user operating the mobile phone 200 has requested to save an image from the digital camera 100 to the mobile phone 200. If there is an image acquisition request, the process proceeds to step S822. If there is no image acquisition request, the process proceeds to step S823.
In step S822, the control unit 201 acquires image data from the digital camera 100, and the process returns to step S821.
In step S823, the control unit 201 determines the end of the application due to a user operation or a stop command from the operating system. If the application is terminated, the process is terminated. If the application is not terminated, the process returns to step S821.

<Matching log information and image information>
The matching process between log information and image information in step S818 will be described.
FIG. 9A shows an example of log information 901 recorded and stored by the mobile phone 200.
FIG. 9B shows an example of a list 902 of image information in the digital camera. Each image information constituting the image information list 902 has at least a device type, a device ID, a shooting date, and an object handle uniquely determined as a file in the digital camera in one image.
