Further, different single imaging conditions are set in the plurality of electronic cameras according to the acquired performances. From such a plurality of electronic cameras, a plurality of electronic images are respectively acquired by imaging instructions. Therefore, even when the performances of the plurality of electronic cameras are different from each other, a homogeneous image can be obtained without requiring any special operation, and the operability is improved.

Referring to FIG. 35, the electronic camera of this embodiment is basically configured as follows. The imaging unit 1 outputs an electronic image representing an optical image captured on the imaging surface. The device connection means 2 connects with an electronic device. The performance transmission unit 3 transmits the imaging performance to the electronic device connected by the device connection unit 2 in order to determine a different single imaging condition according to the performance of each of the plurality of electronic cameras.

The image acquisition unit 5 acquires an electronic image output from the imaging unit 1 in association with the imaging instruction transmitted from the electronic device connected by the device connection unit 2.

In order to determine different single imaging conditions according to the performance of each of the plurality of electronic cameras, the performance of the electronic camera is transmitted to the connected electronic device. Further, the imaging condition is changed in association with the change instruction transmitted from the electronic device, and the electronic image output from the imaging unit is acquired in association with the imaging instruction transmitted from the electronic device. Therefore, even when the performance of each of the plurality of electronic cameras is different from each other, a single imaging condition that differs depending on each performance is set in the plurality of electronic cameras. For this reason, a homogeneous image can be obtained without requiring a special operation, and the operability is improved.

The camera system of this embodiment includes one or more digital cameras 10 each configured as shown in FIG. 1 or 2 and one or more smartphones 50 each configured as shown in FIG. And formed by. Both the digital camera 10 and the smartphone 50 have a short-range wireless communication function according to the AdHoc method or the Wi-FiDirect method. Note that the short-range wireless communication is executed by the communication I / F 42 shown in FIG. 1 or 2 and the communication I / F 64 shown in FIG.

When the digital camera 10 and the smartphone 50 are turned on, the camera operation function of the smartphone 50 is activated, and the smartphone 50 is moved to the vicinity of the digital camera 10, live image data representing a scene photographed by the digital camera 10 is obtained. It is transferred to the smartphone 50 by short-range wireless communication (see FIG. 4). When a zoom operation is performed on the smartphone 50, a zoom instruction is given to the digital camera 10 by short-range wireless communication, and the zoom magnification is changed in response thereto. Further, when an imaging operation is performed on the smartphone 50, an imaging instruction is given to the digital camera 10 by short-range wireless communication. Still image data representing a scene at the time when an imaging instruction is given is transferred from the digital camera 10 to the smartphone 50 by short-range wireless communication.

The digital camera 10 shown in FIG. 1 is assumed to be taken by a general consumer and photograph a desired scene at home or on the road. In contrast, the digital camera 10 shown in FIG. 2 is assumed to be installed at a plurality of positions in a tourist spot such as a theme park and observe fixed points. Therefore, in comparison with the digital camera 10 shown in FIG. 1, the key input device 34, the LCD driver 28, and the LCD monitor 30 are omitted in the digital camera 10 shown in FIG.

The digital camera 10 shown in FIG. 2 is mounted on a radio controlled car, a radio controlled airplane, a rock climber's helmet or an animal, or embedded in a ball for ball games in order to shoot an unusual scene. Also good. The digital camera 10 shown in FIG. 2 may also be installed in a refrigerator for managing cold objects, or attached to a security guard's flashlight for photographing the security area.

1 or 2, the digital camera 10 includes a zoom lens 12, a focus lens 14, and a diaphragm mechanism 16 that are driven by

drivers

20a, 20b, and 20c, respectively. The optical image that has passed through these members is irradiated onto the imaging surface of the imaging device 18 and subjected to photoelectric conversion. As a result, a charge representing the scene captured on the imaging surface is generated.

The camera CPU 32 executes a plurality of tasks including a camera-side imaging control task, a camera-side display control task, a response processing task, a camera-side connection control task, and a camera-side communication control task in parallel on the multitask OS. It is. Control programs corresponding to these tasks are stored in the flash memory 40. The camera side display control task is omitted in the digital camera 10 shown in FIG.

When the power is turned on, the camera side imaging control task instructs the driver 20d to repeat the exposure operation and the charge readout operation in order to start the moving image capturing process. In response to a vertical synchronization signal Vsync periodically generated from an SG (SignalｓGenerator) (not shown), the driver 20d exposes the imaging surface and reads out the charges generated on the imaging surface in a raster scanning manner. From the imaging device 18, raw image data based on the read charges is periodically output.

The camera processing circuit 22 performs processing such as color separation, white balance adjustment, and YUV conversion on the raw image data output from the imaging device 18, and the YUV format image data generated thereby is stored in the SDRAM 26 through the memory control circuit 24. Write in the YUV image area 26a.

In the digital camera 10 shown in FIG. 1, the camera side display control task instructs the LCD driver 28 to start the moving image display process. The LCD driver 28 repeatedly reads out the image data stored in the YUV image area 26a through the memory control circuit 24, and drives the LCD monitor 30 based on the read image data. As a result, a live image representing a scene captured on the imaging surface is displayed on the monitor screen.

The image data created by the camera processing circuit 22 is also given to the camera CPU 32. The camera-side imaging control task performs simple AE processing on the given image data to calculate an appropriate EV value, and sets the aperture amount and the exposure time that define the calculated appropriate EV value in the

drivers

20c and 20d, respectively. As a result, the brightness of the image data is adjusted appropriately.

1 is operated, the camera-side imaging control task instructs the driver 20a to execute zoom processing. The zoom lens 12 is moved in the zoom-in direction or the zoom-out direction by the driver 20a, thereby changing the magnification of the image data.

1 is operated, the camera side display control task instructs the LCD driver 28 to interrupt the moving image display process. As a result, the display on the LCD monitor 30 is updated from the live image to the black image.

On the other hand, the camera-side imaging control task performs strict AE processing on the image data output from the camera processing circuit 22 to calculate the optimum EV value, and sets the aperture amount and exposure time defining the calculated optimum EV value to the driver 20c. And 20d, respectively. The brightness of the image data is adjusted to an optimum value. Subsequently, the camera-side imaging control task executes AF processing with reference to the high-frequency component of the image data output from the camera processing circuit 22. The focus lens 14 is placed at the focal point by the driver 20b, and thereby the sharpness of the image data is improved.

When the AF process is completed, the camera side imaging control task executes the still image capturing process and commands the memory I / F 36 to execute the recording process. One frame of image data representing the scene at the time when the AF process is completed is saved in the still image area 26b of the SDRAM 26 by the still image capturing process. The memory I / F 36 instructed to execute the recording process reads the image data saved in the still image area 26 b through the memory control circuit 24 and records an image file containing the read image data on the recording medium 38. .

The camera side display control task instructs the LCD driver 28 to resume the moving image display process after the recording process is completed. The LCD driver 28 resumes reading the image data stored in the YUV image area 26a, and as a result, the display on the LCD monitor 30 is returned to the live image.

Referring to FIG. 3, the smartphone 50 includes an antenna 52 for mobile communication and a wireless communication module. If the transmitted / received data is call voice data, the received voice is output from the speaker 56 and the transmitted voice is captured by the microphone 58. If the transmission / reception data is image data, this data is processed under the control of the smartphone CPU 60.

The target image data is written into the SDRAM 68 through the memory control circuit 66. The LCD driver 70 reads the image data stored in the SDRAM 68 through the memory control circuit 66, and drives the LCD monitor 72 based on the read image data. As a result, a corresponding image is displayed on the monitor screen. A touch operation on the monitor screen is detected by a touch sensor 78. The detection result is given to the smartphone CPU 60, and different processes are executed under the control of the smartphone 60 according to the mode of the touch operation.

The smartphone CPU 60 is also a processor that executes a plurality of tasks in parallel on the multitasking OS. As tasks to be executed, a search processing task, a phone side connection control task, a phone side communication control task, a phone side display control task, and a phone side imaging control task are prepared. Control programs corresponding to these tasks are stored in the flash memory 62.

In the smartphone 50, the search processing task executes a process for initializing the search register RGSTs and a process for issuing a response request shown in FIG. 6A every time a search cycle (= 10 seconds) arrives. The issued response request describes its own phone ID, and the response request is issued from the communication I / F 64 by the broadcast method.

When the response request is received by the communication I / F 42 of the digital camera 10, the response processing task returns an ACK through the communication I / F 42. The returned ACK describes the camera ID for identifying itself and the requesting phone ID. The digital camera 10 belongs to one of a plurality of predefined groups, and a group ID for identifying the group to which the digital camera 10 belongs is assigned to the digital camera 10. This group ID is added to the camera ID described in ACK in an expanded manner.

When the ACK describing its own phone ID is received by the communication I / F 64 of the smartphone 50, the search processing task extracts the camera ID described in the received ACK and uses the extracted camera ID as a search register RGSTs. Register with. The group ID added to the camera ID in an expanded manner is registered in the search register RGSTs corresponding to the camera ID.

Thus, when at least one camera ID is registered in the search register RGSTs, the phone side connection control task instructs the LCD driver 70 to display the group menu. The LCD driver 70 detects one or more group IDs from the search register RGSTs, and displays the detected group IDs on the LCD monitor 72 as a group menu.

When a touch operation (= group selection operation) for selecting one of the displayed group IDs is detected by the touch sensor 78, the phone side connection control task initializes the connection register RGSTc shown in FIG. And issues a connection request through the communication I / F 64. The issued connection request describes its own phone ID and specification information, and further describes one or more camera IDs described in the search register RGSTs corresponding to the selected group ID. As the specification information, for example, the resolution of the LCD monitor 72 is assumed.

When the connection request issued from the smartphone 50 is received by the communication I / F 42 of the digital camera 10, the camera-side connection control task executes an authentication process on the received connection request. If the connection with the requesting smartphone 50 is approved as a result of the authentication processing, the camera side connection control task transmits an ACK in which the camera ID of the camera and the requesting phone ID are described through the communication I / F 42. .

Subsequently, the camera side connection control task extracts the request source phone ID and specification information from the connection request, and registers the extracted phone ID and specification information in the register RGST1 shown in FIG. Furthermore, when the number of phone IDs registered in the register RGST1 is updated from “0” to “1”, the camera-side connection control task notifies other tasks of establishment of the connection with the smartphone 50.

The camera-side display control task that has received this notification interrupts the display of the live image on the LCD monitor 30. The display on the LCD monitor 30 is updated from a live image to a black image in response to the connection with the smartphone 50.

The camera side connection control task also issues a response request through the communication I / F 42 every time the confirmation cycle (= 5 seconds) arrives. The issued response request describes its own camera ID and one or more phone IDs registered in the register RGST1.

When this response request is received by the communication I / F 64 of the smartphone 50, the phone side connection control task determines that the phone ID that matches its own phone ID and the camera that matches any camera ID registered in the connection register RGSTc. An ACK is returned only when the ID is described in the response request. The returned ACK describes its own phone ID and the requesting camera ID.

In the digital camera 10, the camera-side connection control task refers to the reception status of the ACK returned in this way, and identifies the smartphone 50 that is unable to maintain the connection. The identified phone ID and specification information of the smartphone 50 are deleted from the register RGST1.

As a result of the deletion, when the number of phone IDs registered in the register RGST1 is updated from “1” to “0”, the camera side connection control task notifies the other task of the release of the connection with the smartphone 50. Upon receiving this notification, the camera-side display control task resumes displaying the live image on the LCD monitor 30. The display on the LCD monitor 30 is updated from a black image to a live image in response to the release of the connection with the smartphone 50.

The live image representing the scene captured by the digital camera 10 is displayed on the LCD monitor 72 of the connected smartphone 50 (details will be described later). When a disconnection operation specifying the displayed live image is performed, the phone side connection control task issues a disconnection request in which the camera ID for identifying the transmission source of the specified live image and its own phone ID are described. It transmits through communication I / F64. The camera ID that identifies the transmission source of the designated live image is then deleted from the connection register RGSTc.

When the disconnection request issued from the smartphone 50 is received by the communication I / F 42 of the digital camera 10, the camera side connection control task deletes the requester's phone ID and specification information from the register RGST1. When the number of phone IDs registered in the register RGST1 is updated from “1” to “0”, the display of the live image on the LCD monitor 30 is resumed as described above.

When at least one phone ID is registered in the register RGST1, the camera side communication control task instructs the communication I / F 42 to start the moving image transfer process. The camera-side communication control task also selects a specification representing the minimum quality from one or more specifications registered in the register RGST1, and sets the transfer image quality conforming to the selected specification in the communication I / F 42. The transfer quality set in the communication I / F 42 is updated every time the description of the register RGST1 is updated in the range where the number of registered camera IDs is “1” or more.

The communication I / F 42 periodically reads the image data stored in the YUV image area 26a through the memory control circuit 24, and adjusts the quality of the read image data with reference to the transfer image quality set as described above. Then, the image data having the adjusted quality is transferred to the smartphone 50 as live image data. Note that the broadcast method is adopted as the transfer method. Further, one or more camera IDs registered in the register RGST1 are embedded in the live image data to be transferred. When the description of the register RGST1 is updated, the camera ID embedded in the live image data is also updated.

As a specification registered in the register RGST1, the resolution of the LCD monitor 72 provided in the smartphone 50 is assumed. When the three

smartphones

50, 50 and 50 are connected to the digital camera 10, the phone ID and specifications of each smartphone 50 are described in the register RGST1, for example, in the manner shown in FIG.

7, the phone ID of the first smartphone 50 is “PH_A”, and the LCD monitor 72 of the first smartphone 50 has a resolution of 640 pixels × 960 pixels. The phone ID of the second smartphone 50 is “PH_B”, and the LCD monitor 72 of the second smartphone 50 has a resolution of 320 pixels × 480 pixels. Further, the phone ID of the third smartphone 50 is “PH_C”, and the LCD monitor 72 of the third smartphone 50 has a resolution of 768 pixels × 1024 pixels.

At this time, the camera side communication control task selects a resolution of 320 pixels × 480 pixels as the specification of the minimum quality, and sets the selected resolution in the communication I / F 42 as the transfer image quality. The live image data transferred by the communication I / F 42 has a resolution of 320 pixels × 480 pixels.

When at least one camera ID is registered in the connection register RGSTc, the phone side communication control task starts reception of live image data in which a camera ID matching the camera ID described in the connection register RGSTc is embedded. A corresponding command is given to the communication I / F 64. The phone side communication control task also measures the reception intensity of the live image data received by the communication I / F 64 (strictly, the intensity of the radio wave corresponding to the live image data) for each transmission source (= for each camera ID), The arrangement of the received live image data is determined for each transmission source (= each camera ID). According to the determined arrangement, the live image data is arranged in descending order of the measured reception intensity.

The live image data received by the communication I / F 64 is given to the memory control circuit 66. The memory control circuit 66 writes the given live image data in the SDRAM 68 with reference to the arrangement determined in the above manner.

The phone side communication control task also detects the transmission source of live image data whose reception intensity is below the standard (= live image data that cannot be received) every time the confirmation cycle (= 3 seconds) arrives. The camera ID that identifies the detected transmission source is deleted from the connection register RGSTc. The reception mode of the live image data by the communication I / F 64 reflects the description of the connection register RGSTs after the deletion process. The reception of live image data is stopped when the number of camera IDs registered in the connection register RGSTc is updated from “1” to “0”.

When reception of live image data is started by the phone side communication control task, the phone side display control task instructs the LCD driver 70 to start displaying the live image. The LCD driver 70 reads the live image data stored in the SDRAM 68 through the memory control circuit 66 and drives the LCD monitor 72 based on the read live image data. As a result, one or more live images are displayed on the monitor screen in the order according to the reception intensity.

When the four

digital cameras

10, 10,... Are connected to the smartphone 50, the camera ID is described in the connection register RGSTc, for example, as shown in FIG. According to FIG. 8A, the camera ID of the first digital camera 10 indicates “CM_A”, the camera ID of the second digital camera 10 indicates “CM_B”, and the third digital camera 10 The camera ID of “4” indicates “CM_C”, and the camera ID of the fourth digital camera 10 indicates “CM_D”.

Based on this, when the reception intensity of the live image data received by the communication I / F 64 decreases in the order of “CM_A” → “CM_B” → “CM_C” → “CM_D”, four live images LV_A, LV_B, LV_C and LV_D are displayed on the LCD monitor 72 in the manner shown in FIG.

The live image LV_A is an image based on live image data in which the camera ID “CM_A” is embedded, and the live image LV_B is an image based on live image data in which the camera ID “CM_B” is embedded. The live image LV_C is an image based on live image data in which the camera ID “CM_C” is embedded, and the live image LV_D is an image based on live image data in which the camera ID “CM_D” is embedded.

Thereafter, when the reception intensity of the live image data in which the camera ID “CM_B” is embedded is lower than the reception intensity of the live image data in which the camera ID “CM_D” is embedded, the display state of the LCD monitor 72 is as shown in FIG. The state is updated to the state shown in FIG. According to FIG. 9B, the four live images are arranged in the order of LV_A → LV_C → LV_D → LV_B. At this time, the description of the connection register RGSTc remains the same (see FIG. 9A).

However, if the reception intensity of the live image data in which the camera ID “CM_B” is embedded is below the reference at the time of the next confirmation cycle, the camera ID “CM_B” is obtained from the connection register RGSTc as shown in FIG. Deleted. As a result of the deletion, the reception of the live image data in which the camera ID “CM_B” is embedded is stopped, and the live image LV_B disappears from the LCD monitor 72 as shown in FIG.

When an operation for selecting any one of the live images displayed on the LCD monitor 72 (= image selection operation) is performed, the phone-side display control task instructs the LCD driver 70 to enlarge the selected live image. The LCD driver 70 executes processing according to the command, and as a result, the selected live image is enlarged. When the selection canceling operation is performed in the enlarged display state, the phone side display control task instructs the LCD driver 70 to end the enlarged display. The LCD driver 70 executes processing according to the command, and as a result, the size of the enlarged live image is returned to the original size.

When the display of the live image is started by the phone side display control task, the phone side imaging control task starts to accept the zoom operation and the imaging operation. Here, the zoom operation corresponds to an operation of pinching in or out of a desired live image, and the imaging operation corresponds to an operation of touching the desired live image twice in succession.

When a zoom operation is performed on a desired live image displayed on the LCD monitor 72, the phone side imaging control task issues a zoom instruction through the communication I / F 64. In the issued zoom instruction, zoom magnification information according to the pinch-in operation or pinch-out operation, the camera ID of the source of the desired live image, and the own phone ID are described.

When the zoom instruction issued from the smartphone 50 is received by the communication I / F 42, the camera-side imaging control task determines that the camera ID described in the zoom instruction matches the own camera ID and the phone described in the zoom instruction. The zoom process is executed on the condition that the ID matches any phone ID registered in the register RGST1. The zoom lens 12 is moved in the zoom-in direction or the zoom-out direction by the driver 20a. As a result, the magnification of the desired live image displayed on the LCD monitor 72 of the smartphone 50 changes.

When an imaging operation for a desired live image displayed on the LCD monitor 72 is performed, the phone side imaging control task issues an imaging instruction through the communication I / F 64. In the issued imaging instruction, the camera ID of the transmission source of the desired live image and the own phone ID are described. The phone side imaging control task also instructs the LCD driver 70 to interrupt the display of a desired live image after issuing the imaging instruction. As a result, the desired live image is updated to a black image.

The user of the smartphone 50 can visually recognize that the imaging instruction has been issued by updating the display image from the live image to the black image. When the still image acquired from the digital camera 10 is displayed on the LCD monitor 70 for preview, if the display of the black image is omitted, the display on the LCD monitor 70 is updated from the live image to the still image, This may confuse the user of the smartphone 50. The display of the black image also brings an advantage of avoiding confusion of the user of the smartphone 50 when displaying a still image as a preview.

When the imaging instruction issued from the smartphone 50 is received by the communication I / F 42, the camera-side imaging control task causes the camera ID described in the imaging instruction to match the own camera ID and the phone described in the imaging instruction. A series of processes including a strict AE process, an AF process, and a still image capturing process is executed on condition that the ID matches one of the phone IDs registered in the register RGST1.

When the still image capturing process is completed, the camera side communication control task instructs the communication I / F 42 to transfer the still image data acquired thereby. The communication I / F 42 reads the still image data saved in the still image area 26b through the memory control circuit 24, and transfers the read still image data to the issuer of the imaging instruction. Here, the unicast method is adopted as the transfer method, and the phone ID of the issuer of the imaging instruction is embedded in the transferred still image data.

When the still image data from the issue destination of the imaging instruction is received by the communication I / F 64, the phone side imaging control task instructs the memory I / F 74 to record the received still image data. The received still image data is recorded in the flash memory 74 in a file format by the memory I / F 74. When the recording is completed, the phone side imaging control task gives the LCD driver 70 resumption of display of the interrupted live image. As a result, display of a desired live image is resumed.

In relation to the processing of the camera CPU 32, the camera side imaging control task is configured as shown in FIG. 11, the camera side display control task is configured as shown in FIG. 12, and the response processing task is configured as shown in FIG. The camera side connection control task is configured as shown in FIGS. 14 to 15, and the camera side communication control task is configured as shown in FIGS. Here, the task priority decreases in the order of camera-side imaging control task → camera-side communication control task → camera-side display control task → response processing task → camera-side connection control task. As described above, the camera-side display control task shown in FIG. 12 is omitted in the digital camera 10 shown in FIG.

Referring to FIG. 11, in step S1, the moving image capturing process is started. As a result, raw image data representing a scene captured on the imaging surface is periodically output from the imaging device 18, and corresponding YUV format image data is periodically output from the camera processing circuit 22.

In step S3, an imaging instruction (a camera ID that matches the camera ID of the camera and a phone ID that matches any phone ID registered in the register RGST1 is issued by operating the shutter button 34sh or from the smartphone 50). It is determined whether or not a logical sum condition that the communication I / F 42 is received) is satisfied. If a determination result is NO, it will progress to step S5 and will perform a simple AE process. As a result, the brightness of the image data output from the camera processing circuit 22 is adjusted appropriately.

In step S7, the zoom button 34z is operated or a zoom instruction issued from the smartphone 50 (a camera ID that matches the own camera ID and a phone ID that matches any phone ID registered in the register RGST1). It is determined whether or not a logical OR condition that the communication I / F 42 is received) is satisfied. If the determination result is NO, the process directly returns to step S3, whereas if the determination result is YES, the zoom process is performed in step S9, and then the process returns to step S3. As a result of the zoom process, the zoom lens 12 moves in the zoom-in direction or the zoom-out direction, and the magnification of the image data output from the camera processing circuit 22 changes.

If the decision result in the step S3 is YES, a strict AE process is executed in a step S11, and an AF process is executed in a step S13. The brightness of the image data is adjusted to an optimum value by the strict AE process, and the sharpness of the image data is improved by the AF process. When the process of step S13 is completed, a still image capturing process is executed in step S15. One frame of image data representing a scene at the time when AF processing is completed is saved as still image data from the YUV image area 26a to the still image area 26b.

In step S17, it is determined whether or not the trigger for updating the determination result in step S3 from NO to YES is an operation of the shutter button 34sh. If the determination result is NO, that is, if the trigger is an imaging instruction from the smartphone 50, the process directly returns to step S3. On the other hand, if the determination result is YES, that is, if the trigger is an operation of the shutter button 34sh, the memory I / F 36 is commanded to execute the recording process in step S19.

The memory I / F 36 reads the still image data saved in the still image area 26b through the memory control circuit 24, and records an image file containing the read still image data on the recording medium 38. When the recording process is completed, the process returns to step S3.

Referring to FIG. 12, the moving image display process is started in step S21. As a result, a live image representing a scene captured on the imaging surface is displayed on the LCD monitor 30. In step S23, it is determined whether or not the shutter button 34sh has been operated. In step S25, it is determined whether or not a connection with at least one smartphone 50 has been established. The determination process in step S25 is executed based on the notification issued in step S63 described later.

When the determination result in step S23 is updated from NO to YES, the moving image display process is interrupted in step S27. The display on the LCD monitor 30 is updated from a live image to a black image. In step S29, it is determined whether or not the recording process in step S19 shown in FIG. 11 is completed. When the determination result is updated from NO to YES, the moving image display process is restarted in step S31, and then the process returns to step S23.

When the determination result in step S25 is updated from NO to YES, the moving image display process is interrupted in step S23. The display on the LCD monitor 30 is updated from a live image to a black image, as described above. In step S35, it is determined whether or not the connection with all the

smartphones

50, 50,. This determination processing is executed based on the notification issued in step S77 described later. When the determination result is updated from NO to YES, the process returns to step S23 through the process of step S31.

Referring to FIG. 13, in step S41, it is determined whether or not a response request has been received by communication I / F. When the determination result is updated from NO to YES, the process proceeds to step S43, and ACK is returned through the communication I / F 42. The received response request describes the phone ID that identifies the requesting smartphone 50, and the ACK returned in step S43 describes the camera ID that identifies itself and the requesting phone ID. When the return process is completed, the process returns to step S41.

The digital camera 10 belongs to any one of a plurality of predefined groups, and a group ID for identifying the group to which the digital camera 10 belongs is assigned to the digital camera 10. This group ID is added to the camera ID described in ACK in step S43 in an expanded manner.

Referring to FIG. 14, in step S <b> 51, it is determined whether or not a connection request issued from the surrounding smartphone 50 has been received by the communication I / F 42. In the connection request, specification information indicating the specification of the requesting smartphone 50 is described in addition to the requested camera ID and the requesting phone ID. If the decision result in the step S51 is YES, an authentication process is executed in a step S53. In step S55, it is determined whether or not the connection with the requesting smartphone 50 has been approved based on the result of the authentication process. If the determination result is NO, the process returns to step S51, whereas if the determination result is YES, step S57. Proceed to

In step S57, an ACK describing its own camera ID and requesting phone ID is transmitted through the communication I / F 42. In step S59, the request source phone ID and specification information are extracted from the connection request, and the extracted phone ID and specification information are registered in the register RGST1. In step S61, it is determined whether or not the number of phone IDs registered in the register RGST1 is “1”. If the determination result is NO, the process returns to step S51, whereas if the determination result is YES, the process proceeds to step S63. . In step S63, the establishment of the connection with the smartphone 50 is notified to other tasks. When the notification is completed, the process returns to step S51.

If the determination result in the step S51 is NO, it is determined whether or not at least one phone ID is registered in the register RGST1 in a step S65. If a determination result is NO, it will return to Step S51, and if a determination result is YES, it will progress to Step S67.

In Step S67, it is determined whether or not a non-connection request issued from the connected smartphone 50 is received by the communication I / F 42. In the non-connection request, the request source phone ID and the request destination camera ID are described. Whether or not the requesting smartphone 50 is connected to itself is determined based on the description in the register RGST1 and the phone ID described in the non-connection request.

If the determination result is YES, the process proceeds to step S69, and the requesting phone ID and specification information are deleted from the register RGST1. In step S71, it is determined whether or not the number of phone IDs registered in the register RGST1 is “0”. If a determination result is NO, it will return to step S51 as it is. On the other hand, if a determination result is YES, it will progress to step S73 and will notify cancellation | release of the connection with the smart phone 50 to another task. When the notification is completed, the process returns to step S51.

If the determination result in the step S67 is NO, it is determined in a step S75 whether or not a confirmation cycle (= 5 seconds) has come. If a determination result is YES, it will progress to step S77 and will issue a response request through communication I / F42. The issued response request describes its own camera ID and one or more phone IDs registered in the register RGST1.

The smartphone 50 having the same phone ID as the phone ID described in the response request returns an ACK by the process of step S165 described later. In the returned ACK, the return source phone ID and the return destination camera ID are described. In step S79, referring to the reception status of the ACK returned in this manner, the smartphone 50 that cannot maintain the connection is specified. The identified phone ID and specification information of the smartphone 50 are deleted from the register RGST1 in step S69.

Referring to FIG. 16, in step S81, it is determined whether or not a connection with at least one smartphone 50 has been established. This determination process is executed based on the notification issued in step S63 described above. When the determination result is updated from NO to YES, the process proceeds to step S83 to command the communication I / F 42 to start the moving image transfer process. In step S85, a specification representing the minimum quality is selected from one or more specifications registered in the register RGTS1, and in step S87, a transfer image quality that conforms to the specification selected in step S85 is set in the communication I / F 42. To do.

The communication I / F 42 periodically reads the image data stored in the YUV image area 26a through the memory control circuit 24, and adjusts the quality of the read image data with reference to the transfer image quality set in step S87. Then, the image data having the adjusted quality is transferred to the smartphone 50 as live image data. Note that the broadcast method is adopted as the transfer method. Further, one or more camera IDs registered in the register RGST1 are embedded in the live image data to be transferred. When the description of the register RGST1 is updated, the camera ID embedded in the live image data is also updated.

In step S89, it is determined whether or not the description of the register RGST1 has been updated. In step S95, it is determined whether or not an imaging instruction has been given. Note that the imaging instruction to be noticed in step S95 is an instruction in which a camera ID that matches its own camera ID and a phone ID that matches any phone ID registered in the register RGST1 are described.

If the determination result of step S89 is YES, it will be discriminate | determined based on the notification issued by the above-mentioned step S77 whether the connection with the smart phone 50 was cancelled | released. If a determination result is NO, it will return to Step S85, and if a determination result is YES, it will progress to Step S93. In step S93, the communication I / F 42 is commanded to stop moving image transfer processing, and then the process returns to step S81. As a result of the processing in step S93, the communication I / F 42 stops the broadcast transfer of live image data.

When the determination result in step S95 is updated from NO to YES, it is determined in step S97 whether or not the above-described still image capturing process in step S15 is completed. When the determination result is updated from NO to YES, the process proceeds to step S99, and the communication I / F 42 is commanded to transfer the still image data to the issuer of the imaging instruction. The communication I / F 42 reads the still image data saved in the still image area 26b through the memory control circuit 24, and transfers the read still image data to the issuer of the imaging instruction. Here, the unicast method is adopted as the transfer method, and the phone ID that issued the imaging instruction is described in the transferred still image data. In step S101, it is determined whether or not the transfer of the still image data is completed. If the determination result is updated from NO to YES, the process returns to step S89.

In relation to the processing of the smartphone CPU 60, the search processing task is configured as shown in FIG. 18, the phone side connection control task is configured as shown in FIGS. 19 to 20, and the phone side communication control task is shown in FIG. The phone side display control task is configured as shown in FIG. 22, and the phone side imaging control task is configured as shown in FIG.

Referring to FIG. 18, in step S111, it is determined whether a search cycle (= 10 seconds) has come. When the determination result is updated from NO to YES, the search register RGSTs is initialized in step S113, and a response request describing its own phone ID is issued in step S115. The response request is issued in a broadcast manner through the communication I / F 64.

In step S117, it is determined whether or not an ACK describing its own phone ID has been received by the communication I / F 64. In step S119, it is determined whether or not a timeout has occurred. If the determination result of step S119 is NO, it will return to step S117, and if the determination result of step S119 is YES, it will return to step S111.

If the determination result in step S117 is YES, the return source ID described in the received ACK is extracted in step S121, and it is determined in step S123 whether or not the extracted return source ID is a camera ID. If a determination result is NO, it will return to step S117, and if a determination result is YES, it will progress to step S125. In step S125, the extracted camera ID is registered in the search register RGSTs. The group ID added to the camera ID in an expanded manner is registered in the search register RGSTs corresponding to the camera ID. When registration is completed, the process returns to step S111.

Referring to FIG. 19, in step S131, it is determined whether or not at least one camera ID is registered in search register RGSTs. If the determination result is YES, the LCD driver 70 is commanded to display a group menu in step S133. The LCD driver 70 detects one or more group IDs from the search register RGSTs, and displays the detected group IDs on the LCD monitor 72 as a group menu.

In step S137, it is determined whether or not a touch operation (= group selection operation) for selecting any one of the displayed group IDs has been performed based on the output of the touch sensor 78. If the determination result is YES, step S137 is performed. While the process proceeds to S139, if the determination result is NO, the process returns to Step S131. If the determination result in step S131 is NO, the process advances to step S135 to instruct the LCD driver 70 to hide the group menu. As a result, the currently displayed group menu is hidden. When the process of step S135 is completed, the process returns to step S131.

In step S139, the connection register RGSTc is initialized, and in step S141, a connection request is issued through the communication I / F 64. The issued connection request describes its own phone ID and specification information, and further describes one or more camera IDs described in the search register RGSTs corresponding to the selected group ID. In step S143, it is determined whether or not an ACK describing its own phone ID has been received by the communication I / F 64. In step S145, it is determined whether or not a timeout has occurred. Note that the ACK noted in step S143 is an ACK returned in response to the connection request issued in step S141, and is distinguished from the ACK noted in step S117.

If the determination result of step S145 is NO, the process returns to step S143, and if the determination result of step S143 is YES, the process proceeds to step S147. In step S147, the camera ID described in the returned ACK is registered in the connection register RGSTc. Therefore, when a plurality of ACKs are returned in the period until timeout occurs, a plurality of camera IDs are registered in the connection register RGSTc.

If the determination result in step S145 is updated from NO to YES, it is determined in step S149 whether or not at least one camera ID is registered in the connection register RGStc. If a determination result is NO, it will return to Step S131, and if a determination result is YES, it will progress to Step S151.

In step S151, it is determined whether or not a disconnection operation has been performed. In step S159, it is determined whether or not the response request issued in step S77 described above has been received by the communication I / F 64. The non-connection operation is executed by designating one of one or two or more live images displayed on the LCD monitor 72 by processing in step S193 described later.

If the decision result in the step S151 is YES, the process advances to a step S153 to designate the digital camera 10 corresponding to the live image transmission source designated by the non-connection operation. In step S155, a non-connection request in which the camera ID of the designated digital camera 10 and its own phone ID are described is transmitted through the communication I / F 64. In step S157, the camera ID of the designated digital camera 10 is deleted from the connection register RGSTc. When the deletion is completed, the process returns to step S149.

If the determination result of step S159 is YES, the camera ID described in the response request is detected in step S161. In step S163, it is determined whether or not the same camera ID as the detected camera ID is registered in the connection register RGSTc. If the determination result is NO, the process returns to step S149. If the determination result is YES, the process proceeds to step S165. move on. In step S165, an ACK describing its own phone ID and requesting camera ID is transmitted through the communication I / F 64. When the transmission is completed, the process returns to step S149.

Referring to FIG. 21, in step S171, it is determined whether or not at least one camera ID is registered in connection register RGSTc. If the determination result is updated from NO to YES, the process proceeds to step S173. One or more digital cameras 10 registered in the connection register RGSTc start transmitting live image data through the process of step S83 described above. The transmitted camera ID is described in the transmitted live image data. In step S173, a corresponding command is sent to the communication I / F 64 in order to start receiving the live image data thus transmitted (live image data in which the camera ID matching the camera ID described in the connection register RGSTc is embedded). give.

In step S175, the reception intensity of the live image data received by the communication I / F 64 (strictly, the intensity of the radio wave corresponding to the live image data) is measured for each transmission source (= for each camera ID). In step S177, the arrangement of the received live image data is determined for each transmission source (= each camera ID). According to the determined arrangement, the live image data are arranged in descending order of the reception intensity measured in step S175.

The live image data received by the communication I / F 64 is given to the memory control circuit 66. The memory control circuit 66 writes the given live image data in the SDRAM 68 with reference to the arrangement determined in step S177.

In step S179, it is determined whether or not a confirmation cycle (= 3 seconds) has come. If the determination result is NO, the process returns to step S175, whereas if the determination result is YES, the process proceeds to step S181. In step S181, the digital camera 10 that transmits live image data whose reception intensity is equal to or lower than the reference (= live image data that cannot be received) is detected based on the measurement result in step S175. In step S183, the detected digital camera 10 camera is detected. The ID is deleted from the connection register RGSTc. The reception mode of the live image data by the communication I / F 64 reflects the description of the connection register RGSTs after the deletion process. In step S185, it is determined whether or not the number of camera IDs registered in the connection register RGSTc is “0”. If the determination result is NO, the process returns to step S175. If the determination result is YES, the process proceeds to step S187. move on. In step S187, the communication I / F 64 is instructed to stop receiving live image data, and then the process returns to step S171.

Referring to FIG. 22, in step S191, it is determined whether or not reception of live image data is started by the process in step S173, and if the determination result is updated from NO to YES, the process proceeds to step S193. In step S193, a corresponding command is given to the LCD driver 70 to start displaying a live image. The LCD driver 70 reads the live image data stored in the SDRAM 68 through the memory control circuit 66 and drives the LCD monitor 72 based on the read live image data. As a result, one or more live images are displayed on the monitor screen in the order according to the reception intensity.

In step S195, it is determined whether or not an image selection operation for selecting any one of the live images displayed on the monitor screen has been performed. If the determination result is NO, the process proceeds to step S203, and if the determination result is YES, the process proceeds to step S197. In step S197, the LCD driver 70 is instructed to enlarge the selected live image. The LCD driver 70 executes processing according to the command, and as a result, the selected live image is enlarged.

In step S199, it is determined whether or not a selection canceling operation has been performed. If the determination result is NO, the process proceeds directly to step S203. To do. As a result of the processing in step S201, the size of the enlarged live image is returned to the original size. When the process of step S201 is completed, the process proceeds to step S203.

In step S203, it is determined whether or not the reception of live image data is stopped by the process in step S187. When the determination result is updated from NO to YES, the LCD driver 70 is commanded to stop displaying the live image in step S205, and then the process returns to step S191.

Referring to FIG. 23, in step S211, it is determined whether or not live image display has been started by the process of step S193. When the determination result is updated from NO to YES, it is determined whether or not an imaging operation has been performed in step S213, and whether or not a zoom operation has been performed is determined in step S215. Here, the imaging operation corresponds to an operation of touching a desired live image twice in succession. The zoom operation corresponds to an operation for pinching in or pinching out a desired live image.

When the determination result of step S215 is updated from NO to YES, the process proceeds to step S217, and a zoom instruction is issued to the transmission source of the desired live image. The zoom instruction is issued through the communication I / F 64. The issued zoom instruction describes zoom magnification information corresponding to the pinch-in operation or pinch-out operation, the camera ID of the issue destination, and the own phone ID. When the process of step S217 is completed, the process returns to step S211.

If the determination result in step S213 is YES, an imaging instruction is issued to a desired live image transmission source. The imaging instruction is issued through the communication I / F 64, and the issued camera ID and the own phone ID are described in the issued imaging instruction. In step S221, a command corresponding to the LCD driver 70 is given to interrupt the display of a desired live image.

In step S223, it is determined whether or not still image data from the issue destination of the imaging instruction has been received by the communication I / F 64. If the determination result is YES, the process proceeds to step S225 to instruct the memory I / F 74 to record the received still image data. The received still image data is recorded in the flash memory 74 in a file format by the memory I / F 74. When the recording is completed, the process proceeds to step S227. In step S227, a corresponding command is given to the LCD driver 70 in order to resume the display of the live image interrupted by the process of step S221. When the process of step S227 is completed, the process returns to step S211.

As can be seen from the above description, in the digital camera 10, the imaging device 18 outputs raw image data corresponding to the optical image captured on the imaging surface, and the camera processing circuit 22 is based on the output raw image data. Create live image data. The camera CPU 32 wirelessly connects to a plurality of

smartphones

connected smartphones

50, 50,. (S59). The camera CPU 32 also adjusts the quality of the live image data to a different single quality according to the detected performances (S85 to S87), and converts the live image data having the adjusted quality to the

smartphones

50 and 50. ,... Are transferred by the broadcast method (S83). As a result, the load applied to the transfer of live image data can be adjusted adaptively, and the image transfer performance can be improved.

Further, in the smartphone 50, the smartphone CPU 60 receives live image data output from each of the plurality of

digital cameras

10, 10,... Via the communication I / F 64 (S173), and a plurality of based on the received live image data. The live image is displayed on the LCD monitor 72 (S193). The smartphone CPU 60 also measures the strength of radio waves received by the communication I / F 64 for each digital camera 10 (S175), and controls the arrangement of a plurality of live images displayed on the LCD monitor 72 based on the measured strength. (S177). This improves the live image display performance.

According to the processing in steps S75 to S79 and S69 shown in FIG. 15, the phone ID is deleted from the register RGST1 when communication between the digital camera 10 and the smartphone 50 becomes poor due to temporary deterioration of the communication environment. Will be. Such a situation can be avoided by repeatedly issuing a response request and deleting the phone ID from the register RGST1 when no ACK is returned for any response request.

Furthermore, in this embodiment, the multitask OS and control programs corresponding to a plurality of tasks executed thereby are stored in advance in the

flash memories
