  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 schematically shows an example of a camera system 5. The camera system 5 includes a camera 10 and a mobile device 100. The camera 10 is a single-lens reflex camera as an example of an imaging device. The mobile device 100 is a mobile phone terminal as an example of an external device. The mobile device 100 is a so-called smartphone.

  The camera 10 has a function of communicating with the mobile device 100. The portable device 100 has a function of communicating with the camera 10. Specifically, the camera 10 communicates with the mobile device 100 by wireless communication. The portable device 100 communicates with the camera 10 by wireless communication. The portable device 100 communicates with the camera 10 via a wireless LAN. As the wireless communication, short-range wireless communication such as Bluetooth (registered trademark) based on the IEEE802.15 standard as well as wireless communication based on the IEEE802.11 standard can be applied. Note that transmission / reception of information between the camera 10 and the portable device 100 described in the present embodiment is performed by wireless communication unless otherwise specified. For this reason, transmission by wireless communication may be simply abbreviated as “transmission” or the like. Further, reception by wireless communication may be simply abbreviated as “reception”.

  The camera 10 stores the image data generated by the imaging operation according to the shooting instruction in the external memory 180 as an image file. The camera 10 allows the user to specify an image file to be transmitted to the mobile device 100. The camera 10 records a transmission reservation list including storage information indicating the storage location of the image file designated by the user in the external memory 180 described later. The information on the storage location of the image file included in the transmission reservation list includes the file name of the image file to be transmitted specified by the user and the directory name in which the image file is stored. Each time the user designates an image file, the camera 10 adds information on the storage location of the designated image file to the transmission reservation list recorded in the external memory 180 and updates the transmission reservation list.

  When instructed by the user to acquire an image file from the camera 10, the portable device 100 requests the camera 10 for a transmission reservation list request for transmitting the transmission reservation list to the portable device 100. When the portable device 100 acquires the transmission reservation list from the camera 10, the portable device 100 transmits an image data transmission request including storage information indicating file names and directory names included in the transmission reservation list to the camera 10. The camera 10 reads the image file specified by the image data transmission request received from the portable device 100 from the external memory 180 and transmits the read image file data to the portable device 100. The portable device 100 stores image file data received from the camera 10 in a recording medium 240 described later.

  If the portable device 100 does not receive the transmission reservation list from the camera 10 after requesting the transmission reservation list from the camera 10, the portable device 100 requests the camera 10 for list information of image data stored in the external memory 180. The list information is received from the camera 10. The image data list information includes a list of file names and directory names of each image file, and thumbnail image data of each image data. The portable device 100 displays a thumbnail image on the display unit 280 based on the thumbnail image data, and allows the user to select an image file to be transmitted from the camera 10 to the portable device 100. The portable device 100 transmits to the camera 10 an image data transmission request including information indicating the file name and directory name of the image file selected by the user. The camera 10 reads the image file stored in the location specified by the image data transmission request received from the portable device 100 from the external memory 180 and transmits the read image file data to the portable device 100. The portable device 100 stores image file data received from the camera 10 in a recording medium 240 described later.

  According to the camera system 5, the user can select an image file to be transmitted to the portable device 100 by an operation on the camera 10. Therefore, even if the camera 10 does not transmit list information such as thumbnail image data to the mobile device 100, only the image file desired by the user can be transmitted to the mobile device 100. Although the number of image files stored in the external memory 180 increases, the time required for transmitting the list information to the portable device 100 also increases. However, according to the camera system 5, the time required for transmitting the list information can be omitted. . Further, the communication amount for transmitting the list information to the mobile device 100 can be reduced.

  Also, according to the camera 10, the transmission reservation information is recorded in the external memory 180, so that the user can select an image file at a desired timing. For example, after the user designates an image file to be transmitted to the mobile device 100, the user can record a new image file obtained by newly photographing with the camera 10 by adding it to the transmission reservation list. . As described above, the designated image files can be transmitted in a lump by sandwiching the photographing operation between the operations for designating the image files. In addition to shooting during the operation of specifying the image file, the operation of changing the operation setting of the camera 10 or the editing operation of the image data is sandwiched between the operations of specifying the image file, and the specified image file is Can be sent in batches. Therefore, even if another operation needs to be performed while the image file is specified, it is not necessary to perform the image file specifying operation again from the beginning after the operation.

  FIG. 2 shows an example of the system configuration of the camera 10 together with the external memory 180. The camera 10 includes a camera body 130 and a lens unit 120. The camera 10 is a single-lens reflex camera. The lens unit 120 is an interchangeable lens and can be attached to and detached from the camera body 130. FIG. 2 shows a block configuration of the entire camera 10 in which the lens unit 120 is mounted on the camera body 130.

  The lens unit 120 includes a lens mount having a lens mount contact 121. The camera body 130 includes a camera mount having a camera mount contact 131. When the lens mount and the camera mount are engaged and the lens unit 120 and the camera body 130 are integrated, the lens mount contact 121 and the camera mount contact 131 are connected. The lens MPU 123 is connected to the camera MPU 140 via the lens mount contact 121 and the camera mount contact 131, and controls the lens unit 120 in cooperation with each other while communicating with each other.

  The lens unit 120 includes a lens group 122, a lens driving unit 124, and a lens MPU 123. The subject light passes through a lens group 122 as an optical system of the lens unit 120 and enters the camera body 130. The mirror unit including the main mirror 145 and the sub-mirror 146 can take an advance position that has advanced into the subject light flux centered on the optical axis of the lens group 122 and a retreat position that has retracted from the subject light flux. The sub mirror 146 is displaced in conjunction with the displacement of the main mirror 145. When the main mirror 145 is at a position retracted from the subject light beam, the sub mirror 146 is also at a position retracted from the subject light beam. When the main mirror 145 is in a position where it has advanced into the subject light beam, the sub mirror 146 is also in a position where it has advanced into the subject light beam. When the release button is pushed in, the mirror unit is moved up from the advanced position and displaced to the retracted position. When the imaging operation by the image sensor 132 is completed, the mirror unit is lowered from the retracted position and returned to the advanced position.

  When the mirror unit is in the advanced position, the main mirror 145 reflects a part of the subject light flux that has passed through the lens group 122. Specifically, a half mirror is formed in a partial region of the main mirror 145. Part of the subject light beam incident on the half mirror region of the main mirror 145 is transmitted and the other part is reflected. The subject luminous flux reflected by the main mirror 145 is presented to the user as a subject image through the focus plate 161, the transmissive display panel 160, the pentaprism 147, the eyepiece optical system 162, and the finder window 163. The user can confirm the composition and the like based on the presented subject image. The transmissive display panel 160 presents various information including information indicating the setting state of the imaging operation to the user, along with the subject image based on the subject light flux. The transmissive display panel 160 superimposes on the subject image based on the subject luminous flux and presents various information to the user under the control of the camera MPU 140.

  Part of the subject luminous flux that has passed through the half mirror area of the main mirror 145 is reflected by the sub mirror 146 and guided to the AF unit 142. The AF unit 142 includes a plurality of photoelectric conversion element arrays that receive a subject light beam. The photoelectric conversion element array outputs a signal with a phase match when in a focused state, and outputs a signal with a phase shift when in a front pin state or a rear pin state. The amount of phase shift corresponds to the amount of shift from the focus state. The AF unit 142 detects a phase difference by performing a correlation operation on the output of the photoelectric conversion element array, and outputs a phase difference signal indicating the phase difference to the camera MPU 140.

  The focus state of the lens group 122 is adjusted using the phase difference signal from the AF unit 142 under the control of the camera MPU 140 and the like. For example, the target position of the focus lens included in the lens group 122 is determined by the camera MPU 140 based on the focus state detected from the phase difference signal, and the position of the focus lens is controlled by the control of the lens MPU 123 toward the determined target position. Is done. Specifically, the lens MPU 123 controls the lens driving unit 124 including a focus lens motor as an example, and moves the focus lens constituting the lens group 122. As described above, when the main mirror 145 is lowered to the advanced position and the mirror unit is in the advanced position, the focus state of the lens group 122 is detected by the phase difference detection method, and the focus adjustment is performed. The AF unit 142 is provided with photoelectric conversion elements at a plurality of positions respectively corresponding to the plurality of focus adjustment positions in order to adjust the focus state at each of the plurality of focus adjustment positions within the imaging range by the image sensor 132.

  The photometric element 144 is an example of a photometric unit that measures subject light. The photometric element 144 has a photoelectric conversion element that receives a part of the light beam guided to the pentaprism 147. The luminance information of the subject detected by the photoelectric conversion element included in the photometric element 144 is output to the camera MPU 140 as a photometric value. The camera MPU 140 controls each unit based on the luminance information acquired from the photometric element 144. For example, the camera MPU 140 calculates an AE evaluation value based on the luminance information, and performs exposure control based on the AE evaluation value. When the recording range is set, the camera MPU 140 is based on luminance information detected by a photoelectric conversion element located in a range corresponding to the recording range among the plurality of photoelectric conversion elements included in the photometry element 144. An AE evaluation value may be calculated.

  When the main mirror 145 retracts from the subject light beam, the sub mirror 146 retracts from the subject light beam in conjunction with the main mirror 145. A focal plane shutter 143 is provided on the lens group 122 side of the image sensor 132. The focal plane shutter 143 is a mechanical shutter as an example. When the mirror unit is in the retracted position and the focal plane shutter 143 is in the open state, the subject luminous flux that has passed through the lens group 122 enters the light receiving surface of the image sensor 132. The focal plane shutter 143 controls exposure by opening and closing an optical path of subject light incident on the image sensor 132.

  The imaging element 132 functions as an imaging unit. The image sensor 132 captures an image of the subject using the subject light flux that has passed through the lens group 122. Examples of the image sensor 132 include solid-state image sensors such as CMOS sensors and CCD sensors. The imaging element 132 has a plurality of photoelectric conversion elements that receive the subject light flux, and outputs an analog signal corresponding to the amount of accumulated charge generated by each of the plurality of photoelectric conversion elements to the analog processing unit 133. The analog processing unit 133 performs analog processing such as amplification processing and OB clamping processing on the analog signal output from the image sensor 132 and outputs the analog signal to the A / D converter 134. The A / D converter 134 converts the analog signal output from the analog processing unit 133 into a digital signal representing image data and outputs the digital signal. The image sensor 132, the analog processing unit 133, and the A / D converter 134 are driven by a driving unit 148 that receives an instruction from the camera MPU 140.

  The digital signal output as a digital signal from the A / D converter 134 is input to the ASIC 135 as image data. The ASIC 135 is an integrated circuit in which circuits related to the image processing function are integrated into one. The ASIC 135 uses at least a part of the memory area of the RAM 136 as an example of a volatile memory as a buffer area for temporarily storing image data, and performs various image processing on the image data stored in the RAM 136. Apply. Examples of the image processing performed by the ASIC 135 include noise reduction processing, defective pixel correction, white balance adjustment, color interpolation processing, color correction, gamma correction, contour enhancement processing, and image data compression processing.

  When the image sensor 132 continuously captures images, sequentially output image data is sequentially stored in the buffer area. A plurality of image data obtained by continuously capturing images by the image sensor 132 is sequentially stored in the buffer area as image data of continuous still images or image data of each image constituting the moving image. The RAM 136 also functions as a frame memory that temporarily stores frames when the ASIC 135 processes moving image data.

  Examples of image processing in the ASIC 135 include processing for generating image data for recording, processing for generating image data for display, and image data processing for automatic focus adjustment (AF). Further, the image processing in the ASIC 135 includes processing for detecting the contrast amount for AF processing and the like. Specifically, the ASIC 135 detects the contrast amount from the image data and supplies it to the camera MPU 140. For example, the ASIC 135 detects the contrast amount from each of a plurality of image data obtained by imaging with the focus lens positioned at different positions in the optical axis direction. The camera MPU 140 adjusts the focus state of the lens group 122 based on the detected contrast amount and the position of the focus lens. For example, the camera MPU 140 determines the target position of the focus lens so as to increase the amount of contrast, and causes the lens MPU 123 to control the position of the focus lens toward the determined target position. As described above, when the main mirror 145 is up and in the retracted position, the focus state of the lens group 122 is detected by the contrast detection method, and the focus adjustment is performed. As described above, the camera MPU 140 performs the focus adjustment of the lens group 122 in cooperation with the ASIC 135 and the lens MPU 123.

  When recording the image data output from the A / D converter 134, the ASIC 135 converts the image data into a standardized image format. For example, the ASIC 135 performs a compression process for generating still image data obtained by encoding still image data in an encoding format compliant with a standard such as JPEG. Further, the ASIC 135 converts a plurality of frames into QuickTime, H.264, and the like. H.264, MPEG2, Motion JPEG, etc. A compression process for generating moving image data encoded by an encoding method compliant with a standard such as JPEG is performed. Image data such as still image data and moving image data for recording generated by the ASIC 135 is transferred from the RAM 136 to the external memory 180 through the recording medium IF 152.

  The external memory 180 is attached to the recording medium connector 151. The external memory 180 can be attached to and detached from the camera body 130. The external memory 180 is an example of a nonvolatile recording medium. The external memory 180 is configured by a semiconductor memory such as a flash memory, for example. The external memory 180 may be a memory card. The image data recorded in the external memory 180 is transferred to the RAM 136 through the recording medium IF 152 and stored in the RAM 136.

  The ASIC 135 generates display image data in parallel with the generation of recording image data. For example, the ASIC 135 generates display image data to be displayed on the display unit 138 during a so-called live view operation. Further, at the time of image reproduction, the ASIC 135 generates image data for display from the image data read from the external memory 180. The generated image data for display is converted into an analog signal under the control of the display control unit 137 and displayed on the display unit 138 such as a liquid crystal display. In addition to the image display based on the image data obtained by imaging, various menu items relating to various settings of the camera 10 are also displayed under the control of the ASIC 135 and the display control unit 137 without displaying the image based on the image data. 138.

  A communication cable for communicating with an external device is attached to the external device connector 153. Examples of the communication cable include a USB cable and an HDMI (registered trademark) cable. The camera MPU 140 can transmit the image data stored in the RAM 136 to an external device that is communicably connected via the external device connector 153. The image data stored in the RAM 136 may be image data transferred from the external memory 180 to the RAM 136 through the recording medium IF 152. The ASIC 135 is generated according to the imaging operation of the imaging device 132 and stored in the RAM 136. Image data.

  The camera MPU 140 can receive image data from an external device via the external device connector 153 and the external communication IF 154 and store the image data in the RAM 136. The image data received from the external device and stored in the RAM 136 may be recorded in the external memory 180 under the control of the recording medium IF 152. The display control unit 137 may cause the display unit 138 to display an image based on the image data.

  The wireless communication module 150 performs wireless communication with an external device. For example, the wireless communication module 150 performs wireless communication with the mobile device 100. Specifically, the wireless communication module 150 receives an image data transmission request for transmitting image data from the portable device 100. When the wireless communication module 150 receives a request from the portable device 100 to transmit image data, the camera MPU 140 reads the image data from the external memory 180 to the RAM 136 through the recording medium IF 152, and the image data read to the RAM 136.

  In addition, the wireless communication module 150 receives an imaging request for imaging with the camera 10 from the portable device 100. When receiving an imaging request, the camera MPU 140 performs an imaging operation by controlling the imaging device 132 and the like, and the image data generated by the ASIC 135 according to the imaging operation of the imaging device 132 and stored in the RAM 136 is transmitted from the wireless communication module 150. It transmits to the portable device 100 by radio.

  The operation input unit 141 receives a user operation. The operation input unit 141 includes various operation members such as a release button, a command dial, a multi selector, a menu button, a shooting mode dial, a live view switch, and a power switch. Further, the operation input unit 141 may include a touch sensor that is integrated with the display unit 138 as a touch panel or the like.

  The camera MPU 140 detects that the operation input unit 141 has been operated, and executes an operation corresponding to the operation. For example, the camera MPU 140 controls each unit of the camera 10 so as to execute an imaging operation when a release button is pressed. In addition, the camera MPU 140 controls each unit of the camera 10 so as to perform an operation according to the menu item displayed on the display unit 138 and the operation content when an input member mounted as a touch panel is operated. In this way, the camera MPU 140 specifies a user instruction based on an operation on the operation input unit 141, and executes an operation based on the specified user instruction.

  The camera 10 is controlled directly or indirectly by the camera MPU 140 and the ASIC 135 including the control described above. Constants, parameters such as variables, programs, and the like necessary for the operation of the camera 10 are stored in the system memory 139. The system memory 139 is an electrically erasable / storable nonvolatile memory, and is configured by, for example, a flash ROM, an EEPROM, or the like. The system memory 139 stores parameters, programs, and the like so that they are not lost even when the camera 10 is not operating. Parameters, programs, and the like stored in the system memory 139 are expanded in the RAM 136 and used for controlling the camera 10. The ASIC 135, the RAM 136, the system memory 139, the display control unit 137, the camera MPU 140, the recording medium IF 152, the external communication IF 154, and the wireless communication module 150 are connected to each other via a connection interface 149 such as a bus and exchange various data.

  Each part of the camera body 130, each part of the lens unit 120, and the external memory 180 are supplied with power from the power supply 190 via the power supply circuit 192. Examples of the power source 190 include a secondary battery such as a lithium ion battery that can be attached to and detached from the camera body 130, a system power source, and the like. The secondary battery is an example of a battery, and the battery includes a primary battery that cannot be substantially charged. The camera MPU 140 controls power supply from the power supply 190 to each unit of the camera 10 by controlling the power supply circuit 192.

  FIG. 3 shows an example of a block configuration of the camera MPU 140 of the camera 10. The camera MPU 140 includes an instruction acquisition unit 330, a transmission reservation list recording unit 300, a transmission reservation list transmission unit 340, an image data transmission unit 350, a transmission reservation list update unit 310, and a reception completion notification acquisition unit 320. .

  The instruction acquisition unit 330 acquires an instruction to specify image data from the user. The instruction acquisition unit 330 acquires an instruction to specify image data from the user based on the operation of the operation input unit 141.

  When the instruction acquisition unit 330 acquires an instruction from the user, the transmission reservation list recording unit 300 records a transmission reservation list including information for specifying image data designated by the user in the external memory 180. Image file storage information such as directory names and file names is an example of information for specifying image data.

  The transmission reservation list transmission unit 340 transmits the transmission reservation list recorded in the external memory 180 to the mobile device 100. When the wireless communication module 150 receives the reception transmission reservation list request transmitted from the portable device 100, the transmission reservation list transmission unit 340 reads the transmission reservation list from the external memory 180 by controlling the recording medium IF 152, and the read transmission The reservation list data is transmitted to the mobile device 100.

  When the image data transmission unit 350 receives a transmission request for image data designated based on the transmission reservation list from the portable device 100, the image data transmission unit 350 transmits the image data to the portable device 100. When the image data transmission request 150 is received from the mobile device 100, the image data 150 is read from the external memory 180 by controlling the recording medium IF 152, and the read image file data is transmitted to the mobile device 100.

  The transmission reservation list recording unit 300 displays a transmission reservation list including first information for specifying the first image data when the instruction acquisition unit 330 acquires a first instruction for designating the first image data from the user. Record in the external memory 180. Then, when the instruction acquisition unit 330 acquires a second instruction to specify the second image data obtained by imaging after recording the transmission reservation list including the first information in the external memory 180, The transmission reservation list recording unit 300 adds the second information specifying the second image data to the transmission reservation list, and records the transmission reservation list including the first information and the second information in the external memory 180. The image data transmission unit 350 carries the first image data and the second image data when the portable device 100 is requested to designate and transmit the first image data and the second image data based on the transmission reservation list. Transmit to device 100. Thus, according to the camera 10, since the transmission reservation list is recorded in the external memory 180, other operations such as an imaging operation can be performed while the user makes a transmission reservation.

  The reception completion notification acquisition unit 320 acquires from the portable device 100 a reception completion notification that the portable device 100 has completed reception of image data every time the image data transmission unit 350 transmits image data to the portable device 100. When the reception completion notification acquisition unit 320 acquires the reception completion notification from the mobile device 100, the transmission reservation list update unit 310 deletes information specifying the image data notified from the mobile device 100 from the transmission reservation list. As described above, the transmission reservation list update unit 310 transmits the image data specified by the transmission reservation list recorded in the external memory 180 to the portable device 100 each time the image data transmission unit 350 transmits the image data to the portable device 100. Information for identifying the image data for which transmission has been completed is deleted from the transmission reservation list, and the transmission reservation list recorded in the external memory 180 is updated.

  Note that the ASIC 135 causes the display unit 138 to display an image based on the image data stored in the camera 10 in accordance with an image reproduction instruction acquired from the user. In this case, the camera MPU 140 controls the ASIC 135 so that when the transmission reservation list includes information for specifying the image data of the image displayed on the display unit 138, the image data of the image displayed on the display unit 138 includes other information. The display unit 138 displays the fact that it is designated as image data to be transmitted to the other device together with the image.

  FIG. 4 shows an example of the system configuration of the mobile device 100. The mobile device 100 includes a mobile device MPU 210, a RAM 220, a system memory 230, a recording medium 240, an operation input unit 250, a wireless module 270, a display unit 280, and a bus 290. The bus 290 is coupled to the portable device MPU 210, the RAM 220, the system memory 230, the recording medium 240, the operation input unit 250, the wireless module 270, and the display unit 280, and mutually transmits various data, control signals, and the like output from each unit. .

  The mobile device MPU 210 is a central processing unit and governs overall control of the mobile device 100. The system memory 230 is an electrically erasable / storable nonvolatile memory, and is configured by, for example, a flash ROM. The system memory 230 stores control parameters such as constants and variables necessary for the operation of the mobile device 100, programs, and the like so that they are not lost even when the mobile device 100 is not operating. Constants, variables, programs, and the like stored in the system memory 230 are expanded from the system memory 230 to the RAM 220 and used to control each unit of the mobile device 100. As the RAM 220, SDRAM or the like can be applied.

  The recording medium 240 is a non-volatile recording medium. As the recording medium 240, a semiconductor memory such as a flash memory can be applied. The display unit 280 can be a display device such as a liquid crystal display. The operation input unit 250 receives a user operation. The operation input unit 250 may include operation members such as switches and buttons, and a touch sensor integrated with the display unit 280 as a touch panel. The wireless module 270 performs wireless communication and transmits / receives various data to / from the camera 10.

  The portable device MPU 210 includes a transmission reservation list request unit 410, an image data request unit 420, an image information request unit 430, and a selection control unit 440 as a block configuration.

  The transmission reservation list request unit 410 requests the camera 10 to transmit a transmission reservation list when acquiring an image file from the camera 10. Specifically, the transmission reservation list request unit 410 controls the wireless module 270 to transmit a transmission reservation list request to the camera 10.

  The image data request unit 420 transmits an image file transmission request to the camera 10 based on the transmission reservation list acquired from the camera 10. Specifically, the image data request unit 420 controls the wireless module 270 to transmit an image data transmission request to the camera 10. The image data request unit 420 transmits an image data transmission request including storage information included in the transmission reservation list to the camera 10. For this reason, the camera 10 only has to store the image file stored in the location requested by the image data transmission request as the portable device 100.

  Note that the image information request unit 430, when the transmission reservation list including the information specifying the image data specified by the user cannot be acquired from the camera 10, the image information of one or more image data stored in the camera 10. And the camera 10 are requested to transmit the information specifying the one or more image data. For example, the image information request unit 430 controls the wireless module 270 to transmit a thumbnail information request to the camera 10.

  The selection control unit 440 displays an image based on the image information acquired from the camera 10 on the display unit 280 and allows the user to select image data to be transmitted from the camera 10 to the mobile device 100. The selection control unit 440 determines which image data the user has designated based on the image display position and the user's operation on the operation input unit 250. If the image data requesting unit 420 cannot acquire from the camera 10 a transmission reservation list that includes information for specifying image data specified by the user, the image data requesting unit 420 is based on the information for specifying the image data selected by the selection control unit 440. A transmission request for the image data selected by the selection control unit 440 is transmitted to the camera 10. As described above, the image data request unit 420 can acquire not only the image data selected on the camera 10 but also the image data selected by the user on the portable device 100.

  FIG. 5 schematically shows an example of storage information stored in the transmission reservation list. The transmission reservation list shown in FIG. 5 indicates that three image files are designated as transmission target image files.

  The storage information recorded corresponding to the reservation number 1 in the transmission reservation list is such that a file named “DSC — 0002.JPG” in a directory named “100NK” in the external memory 180 is designated as an image file to be transmitted. Indicates that The storage information recorded in the reservation number 2 of the transmission reservation list indicates that the file named “DSC — 0003.JPG” in the directory named “100NK” in the external memory 180 is designated as the transmission target image file. Show. The storage information recorded in the reservation number 3 of the transmission reservation list indicates that a file named “DSC_0005.JPG” in a directory named “100NK” in the external memory 180 is designated as an image file to be transmitted. Show.

  In the present embodiment, the transmission reservation list is stored in a root directory that is a first layer directory of the external memory 180. The transmission reservation list is stored as a file. “100NK” is a second-level directory belonging to the root directory of the external memory 180. Image files such as “DSC — 0002.JPG” are stored in the “100NK” directory. Note that the transmission reservation list may be stored in a directory in which image files are stored or in a directory below the directory. When the image file is stored in a single specific directory, the storage information in the transmission reservation list may not include the directory name.

  A process when the user adds or deletes an image file as a transmission target image file will be described with reference to FIGS. The initial state will be described assuming that the transmission reservation list shown in FIG. 5 is stored.

  FIG. 6 shows an example of an image playback screen 600. On the playback screen 600, an image based on the image data recorded in the external memory 180 is displayed on the display unit 138 in the playback mode. The playback screen 600 shows a state in which an image based on one image file “DSC — 0006.JPG” selected by the user from among the image files stored in the external memory 180 is displayed.

  The image file “DSC — 0006.JPG” is not included in the transmission reservation list. When the user performs an operation to display the image editing menu on the operation input unit 141 while the reproduction screen 600 is displayed, the camera MPU 140 displays the menu screen 700 illustrated in FIG. 7 on the display unit 138.

  FIG. 7 shows a menu screen 700 for one currently selected image file “DSC — 0006.JPG”. Menu screen 700 includes a selection item 710 of “designation / cancellation of transmission to external device”. When a selection confirmation operation is performed in a state where the selection item 710 is selected by the operation of the operation input unit 141, the instruction acquisition unit 330 of the camera MPU 140 indicates that the user designates “DSC_0006.JPG” as the transmission target image file. to decide. The transmission reservation list recording unit 300 adds the storage information of the file name “DSC — 0006.JPG” and the directory name “100NK” to the transmission reservation list. As a result, storage information of four image files is written in the transmission reservation list. Thus, the user adds the image file “DSC — 0006.JPG” as the transmission target image file by performing a predetermined operation on the operation input unit 141 while the menu screen 700 is displayed. be able to.

  FIG. 8 shows an example of the playback screen 800 after “DSC — 0006.JPG” is designated as the transmission target image file. The playback screen 800 includes a mark 810 indicating a state designated as a transmission target image file. The ASIC 135 causes the mark 810 to be displayed so as to be superimposed on an image based on the image file “DSC — 0006.JPG”.

  When the release button is pressed halfway while the playback screen 800 is displayed, the camera 10 transitions from the playback mode to the shooting standby mode, but the transmission reservation list shows that information of four image files has been written. Maintained. When an operation for setting the operation of the camera 10 is performed in a state where the playback screen 800 is displayed, the camera 10 transitions from the playback mode to the setting mode, but information on four image files is stored in the transmission reservation list. The written state is maintained. Therefore, even if the camera 10 transitions to another operation mode while the transmission target image file is being selected, the information in the transmission reservation list is not lost.

  When the menu screen 700 of FIG. 7 is displayed from the state in which the playback screen 800 is displayed and the selection item 710 of “designation / cancellation of transmission to external device” is selected, the transmission reservation list recording unit 300 The information “DSC — 0006.JPG” is deleted from the transmission reservation list. Therefore, the contents of the transmission reservation list are returned to the contents shown in FIG.

  In FIGS. 6 to 8, the processing in the playback mode has been described. The same processing as the processing described in relation to this playback screen can also be applied to a display screen when an image shot on the display unit 138 is displayed for a certain time after shooting in the shooting mode.

  Next, a case where a plurality of image files are successively designated as transmission target image files will be described with reference to FIGS.

  FIG. 9 shows an example of a menu screen 900 for selecting processing for image data. The menu screen 900 is displayed on the display unit 138 when the image editing menu 980 is selected after the user presses the menu button.

  Menu screen 900 includes a selection item 910 of “designation / cancellation of transmission to external device”. When the selection confirming operation is performed with the selection item 910 selected by the operation of the operation input unit 141, the camera MPU 140 causes the display unit 138 to display the designation screen 1000 illustrated in FIG.

  FIG. 10 is an example of a designation screen 1000 for designating an image file to be transmitted. The designation screen 1000 includes a thumbnail image 1001, a thumbnail image 1002, a thumbnail image 1003, a thumbnail image 1004, a thumbnail image 1005, a thumbnail image 1006, and a cursor 1020 based on image data of six image files.

  When the designation screen 1000 is displayed, the camera MPU 140 controls the ASIC 135 to superimpose the thumbnail image 1002 corresponding to “DSC — 0002.JPG” and that the corresponding image file is designated as the transmission target image file. A mark 1012 is displayed. Similarly, the camera MPU 140 superimposes the thumbnail image 1003 corresponding to “DSC — 0003.JPG” and displays a mark 1013 indicating that the corresponding image file is designated as the transmission target image file. In addition, the camera MPU 140 displays a mark 1015 indicating that the corresponding image file is designated as the transmission target image file, superimposed on the thumbnail image 1005 corresponding to “DSC_0005.JPG”.

  In contrast, a thumbnail image 1001 corresponding to “DSC — 0001.JPG”, a thumbnail image 1004 corresponding to “DSC — 0004.JPG”, and a thumbnail image 1006 corresponding to “DSC — 0006.JPG” are designated as transmission target image files. The mark indicating that it has been displayed is not displayed.

  The camera MPU 140 displays a cursor 1020 at a position corresponding to the currently selected thumbnail image. The cursor 1020 is displayed as a frame surrounding the currently selected thumbnail image. The designation screen 1000 shows a state in which the thumbnail image 1006 is currently selected.

  When the user performs a selection confirmation operation on the operation input unit 141 while the designation screen 1000 is displayed, the instruction acquisition unit 330 of the camera MPU 140 designates “DSC — 0006.JPG” as the transmission target image file. Judge that The transmission reservation list recording unit 300 adds information of the file name “DSC — 0006.JPG” and the directory name “100NK” to the transmission reservation list. As a result, storage information of four image files is written in the transmission reservation list.

  FIG. 11 shows an example of the designation screen 1100 after “DSC — 0006.JPG” is designated as the transmission target image file. The designation screen 1100 includes a mark 1016 indicating a state designated as a transmission target image file. The ASIC 135 superimposes the thumbnail image 1006 and displays a mark 1016 indicating that the corresponding image file is designated as the transmission target image file.

  Subsequently, when an operation for moving the cursor 1020 is performed and a selection confirmation operation is performed in a state where, for example, the thumbnail image 1001 corresponding to “DSC — 0001.JPG” is selected, the instruction acquisition unit 330 of the camera MPU 140 causes the user to “ It is determined that “DSC — 0001.JPG” is designated as the transmission target image file. The transmission reservation list recording unit 300 adds the storage information of the file name “DSC — 0001.JPG” and the directory name “100NK” to the transmission reservation list. As a result, storage information of five image files is written in the transmission reservation list. In this way, the user can continuously specify transmission target image files.

  When the selection confirmation operation is performed in a state where the designation screen 1000 is displayed, the transmission reservation list recording unit 300 deletes the information “DSC_0006.JPG” from the transmission reservation list. Therefore, the contents of the transmission reservation list are returned to the contents shown in FIG.

  FIG. 12 shows an example of an image acquisition screen 1200 displayed on the display unit 280 of the mobile device 100. When the operation input unit 250 is instructed to acquire image data from the camera 10, the portable device MPU 210 displays the image acquisition screen 1200 on the display unit 280. The image acquisition screen 1200 includes a button 1210 that is selected when the camera 10 captures an image and acquires an image file, and a button 1220 that is selected when an image file currently stored in the camera 10 is acquired.

  When the portable device 100 and the camera 10 are wirelessly connected, when the button 1210 is selected on the image acquisition screen 1200, the portable device MPU 210 transmits a shooting instruction from the wireless module 270 to the camera 10. When the camera 10 receives an imaging instruction, the camera MPU 140 performs a shooting operation, stores an image file obtained by the shooting operation in the external memory 180, and transmits data of the image file from the wireless communication module 150 to the portable device 100. Send. When the wireless module 270 receives the image file data, the portable device MPU 210 stores the image file in the recording medium 240 based on the received data and causes the display unit 280 to display an image based on the received data.

  When the portable device 100 and the camera 10 are wirelessly connected, when the button 1220 is selected on the image acquisition screen 1200, the portable device MPU 210 transmits a transmission reservation list request to the camera 10 from the wireless module 270. When the camera 10 receives the transmission reservation list request, the camera MPU 140 transmits the transmission reservation list stored in the external memory 180 to the portable device 100. When acquiring the transmission reservation list, the portable device MPU 210 sequentially transmits image data transmission requests to the camera 10 according to the transmission list. The camera 10 transmits image file data from the wireless communication module 150 to the portable device 100 in accordance with the image data transmission request. When the wireless module 270 receives the image file data, the portable device MPU 210 stores the image file in the recording medium 240 based on the received data.

  In FIG. 13 and FIG. 14, the operation in the mobile device 100 will be described using a flow. In FIG. 15 to FIG. 17, the operation of the camera 10 will be described using a flow.

  FIG. 13 shows an example of an operation flow of a mobile device side application program having functions related to transmission / reception of transmission reservation lists and image data between the mobile device 100 and the camera 10. This flow shows an operation flow from the start to the end of the mobile device side application program. This flow is started when the activation of the mobile device side application program is instructed. This flow is executed by controlling each part of the mobile device 100 mainly by the mobile device MPU 210.

  In step S1302, the mobile device side application program is launched. When wireless communication is established between the wireless communication module 150 and the wireless module 270, a camera-side application program having functions related to transmission / reception list and image data transmission / reception in the camera 10 as part of the processing in step S1302 Establish an application-level connection with When establishing an application level connection, the mobile device MPU 210 acquires information indicating the model of the camera 10 from the camera 10.

  In step S1304, the mobile device MPU 210 determines an operation on the operation input unit 250. Here, an operation for instructing the end of the portable device side application program, an operation for instructing acquisition of image data from the camera 10, and other operations will be described.

  If it is determined in step S1304 that the user operation is an operation for instructing acquisition of image data from the camera 10, the process proceeds to step S1306. If it is determined that the user operation is another operation, the process proceeds to step S1316. If it is determined that the user operation is an operation for instructing to end the mobile device side application program, the process proceeds to step S1318.

  In step S1306, the mobile device MPU 210 displays the image acquisition screen 1200 illustrated in FIG. 12 on the display unit 280 (step S1306).

  Subsequently, it is determined which of the button 1210 and the button 1220 has been selected (step S1308). If the “watch” button 1220 is selected, the process proceeds to step S1310. If the “take” button 1210 is selected, the process proceeds to step S1314.

  In step S1310, processing for acquiring an image file from the camera 10 is performed. The processing in step S1310 will be described with reference to FIG. When the process of step S1310 is completed, a list of images acquired from the camera 10 and stored in the recording medium 240 is displayed on the display unit 280 (step S1312), and the process proceeds to step S1304.

  In step S1314, as described with reference to FIG. 12, a shooting instruction is transmitted to the camera 10, and an image file captured by the camera 10 is acquired and displayed. Description of the details of this process is omitted. When the process of step S1314 is completed, the process proceeds to step S1304.

  In step S1316, a process corresponding to the operation determined in step S1304 is performed, and the process proceeds to step S1304. In step S1318, an operation for terminating the application program is performed, and this flow is terminated.

  FIG. 14 shows an example of an operation flow when the mobile device 100 acquires image data from the camera 10. This operation flow can be applied to the processing in step S1310 of FIG. Here, it is assumed that an application level connection is established with the camera-side application program operating on the camera 10.

  In step S1402, the mobile device MPU 210 determines whether the camera 10 has a function of recording a transmission reservation list. For example, the mobile device MPU 210 determines whether the camera 10 has a function of recording a transmission reservation list based on the model of the camera 10. Specifically, the mobile device MPU 210 determines whether the model of the camera 10 is a model having a function of recording a transmission reservation list.

  In step S1402, if the camera 10 has a function of recording a transmission reservation list, the process proceeds to step S1404. If the camera 10 does not have a function of recording a transmission reservation list, the process proceeds to step S1432.

  In step S1404, the mobile device MPU 210 transmits a transmission reservation list request from the wireless module 270. Next, it is determined whether or not there is a transmission reservation list including image file information (step S1406). For example, when the camera 10 receives a notification that the transmission reservation list including the image file information is not in the camera 10, the determination in step S1406 is N. Even when the transmission reservation list cannot be received from the camera 10, the determination in step S1406 is N. If it is determined that there is no transmission reservation list including image file information, the process advances to step S1432.

  If there is a transmission reservation list, the transmission reservation list is received from the camera 10 in step S1408. Subsequently, in step S1410 to step S1420, image file data is acquired from the camera 10 in accordance with the received transmission reservation list.

  In step S1410, the mobile device MPU 210 selects storage information of one image file from the storage information of the image file existing in the transmission reservation list. Then, the storage information of the selected image file is transmitted to the camera 10 to request transmission of the image file (step S1412).

  In step S1414, it is determined whether image file data has been received. If the image file data could not be received, the process proceeds to step S1420. If a communication error occurs, it is determined that the image file data could not be received. In this case, this image file may be regarded as an image file that has not been subjected to reception processing, and the reception processing of this image file may be retried up to a predetermined number of times.

  If the image file data can be received, the image file generated based on the received data is stored in the recording medium 240 (step S1416). When step S1416 is completed, a reception completion notification indicating that the acquisition of the image file is completed is transmitted to the camera 10 (step S1418). In step S1418, a notification that the acquisition of the image file has been completed may be transmitted to the camera 10 together with the storage information of the image file.

  In step S1420, it is determined whether reception processing has been performed for all image files for which storage information exists in the transmission reservation list. When the reception process is completed for all image files, the operation of this flow is terminated. If reception processing has not been completed for all image files, the process advances to step S1410. In step S1410, image files other than the image files that have been subjected to reception processing so far are selected as image files to be subjected to the next reception processing. One image file is selected.

  In step S1432, a thumbnail information request for requesting transmission of thumbnail information is transmitted to the camera 10, and then thumbnail information is received from the camera 10 (step S1434). The thumbnail information includes thumbnail image data and image file storage information corresponding to the thumbnail image data.

  When the thumbnail information is received, the thumbnail image is displayed on the display unit 280 based on the thumbnail image data (step S1436). Subsequently, the user selects a thumbnail image corresponding to the image file to be acquired from the camera 10 from the thumbnail images displayed on the display unit 280 (step S1438). A reception target list is generated based on the storage information corresponding to the thumbnail image selected by the user (step S1440). The reception target list stores information similar to the information stored in the transmission reservation list.

  In step S1442, image file data is acquired from the camera 10 in accordance with the reception target list. About the process of step S1442, since the process similar to the process from step S1410 to step S1420 can be applied, description is abbreviate | omitted. When the process of step S1442 is completed, the operation of this flow ends.

  FIG. 15 shows an example of an operation flow from activation to termination of the camera 10. This flow is started when the power switch is switched from the OFF position to the ON position. This flow is executed by controlling each part of the camera 10 mainly by the camera MPU 140.

  In step S1502, the camera MPU 140 starts initial setting of the camera 10. For example, the camera MPU 140 expands various parameters for controlling the camera 10 from the system memory 139 to the RAM 136. The camera MPU 140 performs initial setting of the camera 10 based on, for example, various system parameters that have been developed. For example, default imaging conditions are set based on system parameters relating to imaging conditions. Further, when the operation of the wireless communication module 150 is set to ON, processing for starting up the camera side application program is performed as a part of the initial setting.

  Subsequently, in step S1504, the camera MPU 140 causes the display unit 138 or the like to display the content set in the initial setting. For example, the camera MPU 140 displays information such as the determined default imaging condition on the display unit 138 in various formats such as icon display. Here, the camera 10 shifts to a shooting standby mode in which a shooting instruction can be received through a release button or a moving image recording button.

  Subsequently, in step S1506, the event that has occurred is specified. Here, as events, a setting event generated by the operation of the setting button, a shooting event generated by pressing the release button or the movie recording button, a playback event generated by pressing the playback menu through the menu button, and a menu button An image editing event that occurs when the image editing menu is selected and a power-off event are taken up.

  The power off event occurs when the power switch is switched to the OFF position or when the operation input unit 141 has not been operated for a predetermined period.

  When a setting event occurs, the setting mode is entered and a setting process corresponding to the user operation is performed (step S1510). Examples of the setting process include a process for setting an imaging condition and a process for setting a recording condition for image data. Further, as the setting process, a process for setting ON or OFF of the wireless communication function by the wireless communication module 150 can be exemplified. When the operation of the wireless communication module 150 is changed from OFF to ON, processing for starting the camera side application program is performed. When the operation of the wireless communication module 150 is changed from ON to OFF, processing for terminating the operation of the camera side application program is performed.

  When the setting is changed in the setting process, the system parameter is changed according to the changed setting. The setting mode ends when a predetermined operation such as a release button pressing operation is detected, and transitions to the shooting standby mode.

  If it is determined in step S1506 that a shooting event has occurred, a shooting operation is performed (step S1512). The processing in step S1512 includes a still image / moving image capturing operation, image processing on still image / moving image data, and processing of recording the image processed image data in the external memory 180.

  If it is determined in step S1506 that a playback event has occurred, the mode is changed to the playback mode, and a playback operation according to the user operation is performed (step S1514). Examples of the reproduction process include a process of displaying thumbnails based on image data recorded in the external memory 180, a process of reproducing image data selected by the user, and the like. The process of step S1514 will be described with reference to FIG. The operation in the reproduction mode ends when a predetermined operation such as a release button pressing operation is detected, and transitions to the shooting standby mode.

  If it is determined in step S1506 that an image editing event has occurred, the image editing mode is entered and an image editing operation is performed in accordance with a user operation (step S1514). As a part of the image editing operation, the operation related to the designation of the transmission target image file described with reference to FIGS. 9 to 11 is performed. The operation in the image editing mode ends when a predetermined operation such as a release button pressing operation is detected, and transitions to the shooting standby mode.

  When the processes of step S1510, step S1512, step S1514, and step S1516 are completed, the process proceeds to step S1506. If it is determined in step S1506 that a power-off event has occurred, a predetermined termination process for stopping the operation of the camera 10 is performed (step S1522), and this flow is terminated.

  FIG. 16 shows an example of the operation flow of the camera 10 in the playback mode. This operation flow can be applied to the processing in step S1514 in FIG.

  In step S1602, the transmission reservation list is read from the external memory 180. Subsequently, it is determined whether the current image display mode is a thumbnail display mode or a single image display mode (step S1604). In the single image display mode, an image corresponding to one currently selected image file is displayed on the display unit 138 (step S1606), and the process proceeds to step S1610. In the thumbnail display mode, a predetermined number of thumbnail images including a thumbnail image corresponding to one currently selected image file are displayed on the display unit 138 (step S1608), and the process proceeds to step S1610. In step S1606 and step S1608, when an image corresponding to the image file specified as the transmission target image file is displayed, a mark to that effect is superimposed on the image.

  In step S1610, a user operation is determined. Here, as an operation from the user, an operation for instructing display of the image editing menu, an operation for instructing deletion of the image file, an operation for instructing change of the currently selected image file, an operation for instructing the end of the playback mode Will be explained.

  If it is determined in step S1610 that an operation for instructing display of the image editing menu has been performed, the image editing menu is displayed (step S1612). For example, the menu screen 700 illustrated in FIG. 7 is displayed on the display unit 138. Subsequently, the user's menu operation is determined (step S1614). When the menu operation is an operation of selecting “transmission designation / cancellation to external device”, the transmission reservation list is changed (step S1616).

  In step S1616, if the currently selected image file is not designated as the transmission target image file, the storage information of the currently selected image file is added to the transmission reservation list. If the currently selected image file is designated as the transmission target image file, the storage information of the currently selected image file is deleted from the transmission reservation list. When the process of step S1616 is completed, the display state of the mark indicating that it is designated as the transmission target image file is updated (step S1618), and the process proceeds to step S1610.

  If it is determined in step S1614 that the user's menu operation is an operation other than “designate / cancel transmission to external device”, processing according to the menu operation is performed (step S1620), and the process proceeds to step S1610.

  If it is determined in step S1610 that an operation for instructing deletion of the image file has been performed, the image file is deleted (step S1632). Subsequently, it is determined whether or not the image file to be deleted is designated as a transmission target image file (step S1634). If the image file to be deleted is designated as a transmission target image file, a transmission reservation list is determined. (Step S1636), and the process proceeds to step S1638. If the deletion target image file is not designated as the transmission target image file, the process advances to step S1638. In step S1638, the currently selected image file is changed to the next image file, and the process advances to step S1610.

  If it is determined in step S1610 that an operation for instructing change of the currently selected image file has been performed, display for changing the current image file is performed (step S1642), and the process proceeds to step S1610. In step S1642, the cursor position is changed when the current image display mode is the thumbnail display mode, and the image displayed on the display unit 138 is changed when the current image display mode is the single image display mode.

  If it is determined in step S1610 that an operation for instructing the end of the playback mode has been performed, this flow ends.

  FIG. 17 is an example of an operation flow performed based on the camera side application program. This flow is started when the startup of the camera side application program is completed. This flow is executed mainly when the camera MPU 140 operates as a main body.

  In step S1702, the camera MPU 140 identifies the event that has occurred. Here, as events, a transmission reservation list request event that occurs in response to reception of a transmission reservation list request, a thumbnail information request event that occurs in response to reception of a thumbnail information request, and image data that occurs in response to reception of an image data transmission request The transmission request event and the end event are taken up. The end event occurs when the wireless communication function of the wireless communication module 150 is changed from ON to OFF.

  If it is determined in step S1702 that a transmission reservation list request event has occurred, it is determined whether storage information for one or more image files is stored in the transmission reservation list (step S1704). When the storage information of one or more image files is stored in the transmission reservation list, the transmission reservation list is transmitted to the mobile device 100 (step S1706), and the process proceeds to step S1702. If the storage information of the image file is not stored in the transmission reservation list, the camera 10 is notified that there is no transmission reservation list including the image file information in the camera 10 (step S1708), and the process proceeds to step S1702.

  If it is determined in step S1702 that a thumbnail information request event has occurred, the thumbnail information is transmitted to the mobile device 100 (step S1712), and the process proceeds to step S1702.

  If it is determined in step S1702 that an image data transmission request event has occurred, the image file specified by the storage information received from the mobile device 100 is read from the external memory 180 and transmitted to the mobile device 100 (step S1722). Then, it waits to receive notification from the camera 10 that the image file has been received (step S1724). When the notification that the image file has been received is received, the corresponding stored information is deleted from the transmission reservation list (step S1726), and the process proceeds to step S1702. If the notification indicating that the image file has been received has not been received, the process advances to step S1702 without deleting the corresponding stored information from the transmission reservation list.

  If it is determined in step S1702 that an end event has occurred, a program end operation is performed (step S1732), and this flow ends.

  In the present embodiment, the camera 10 and the portable device 100 transmit and receive a transmission reservation list and image data by wireless communication. However, the camera 10 and the portable device 100 may perform transmission / reception of a transmission reservation list and image data by wired communication. For example, the camera 10 and the portable device 100 may transmit and receive a transmission reservation list and image data via a wired LAN. In addition, the camera 10 and the portable device 100 may transmit and receive a transmission reservation list and image data by USB communication. When performing USB communication, the mobile device 100 may communicate as a USB host, and the camera 10 may communicate as a USB device.

  In the present embodiment, the image file and the transmission reservation list are stored in an external memory 180 that can be attached to and detached from the camera body 130. The external memory 180 is an example of a nonvolatile recording medium. The recording medium that stores the image file and the transmission reservation list may not be detachable from the camera body 130. The image file and the transmission reservation list may be stored in a non-volatile recording medium built in the camera body 130. The transmission reservation list is preferably stored in a recording medium that stores the image file, but the transmission reservation list may be stored in a recording medium different from the recording medium that stores the image file. In the case where the image file is stored in a removable recording medium such as the external memory 180, it is preferable to store at least the image file and the transmission reservation list in the same external memory 180. When the image file and the transmission reservation list are stored in the same recording medium, the recording medium is attached to another electronic device such as another camera, and the transmission reservation list and the image data are transferred from the electronic device to the portable device 100. It becomes easy to send.

  In this embodiment, the transmission reservation list is stored in the external memory 180 as a file. However, it may be stored in an image file designated by the user. For example, in the case of an image file in the JPEG format, information indicating whether or not the image file is designated as a transmission target image file may be recorded in the vendor area in the header information of the JPEG file.
