  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 combinations of the features described in the embodiments are necessarily essential to the solution of the invention.

  FIG. 1 schematically shows an example of the 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 mobile 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 mobile device 100 communicates with the camera 10 by wireless communication. The mobile device 100 communicates with the camera 10 via a wireless LAN. As wireless communication, in addition to wireless communication based on the IEEE 802.11 standard, short-range wireless communication such as Bluetooth (registered trademark) based on the IEEE 802.15 standard can be applied. The transmission and reception of information between the camera 10 and the mobile device 100 described in the present embodiment is performed by wireless communication unless otherwise specified. Therefore, transmission by wireless communication may be simply referred to as “transmission” or the like. In some cases, reception in wireless communication is simply referred to as “reception”.

  The camera 10 stores the image data generated by the imaging operation in response 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 specified 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 specifies an image file, the camera 10 adds the information of the storage location of the specified image file to the transmission reservation list recorded in the external memory 180, and updates the transmission reservation list.

  When the mobile device 100 is instructed by the user to acquire an image file from the camera 10, the mobile device 100 requests the camera 10 to transmit a transmission reservation list to the mobile device 100. When acquiring the transmission reservation list from the camera 10, the mobile device 100 transmits an image data transmission request including storage information indicating a file name and a directory name 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 mobile device 100 from the external memory 180, and transmits the data of the read image file to the mobile device 100. The mobile device 100 stores the data of the image file received from the camera 10 in a recording medium 240 described later.

  After requesting the camera 10 for the transmission reservation list, if the transmission reservation list cannot be received from the camera 10, the mobile device 100 requests the camera 10 for list information of the image data stored in the external memory 180. , The list information is received from the camera 10. The list information of the image data includes a list of file names and directory names of each image file, and thumbnail image data of each image data. The mobile 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 mobile device 100. The mobile device 100 transmits an image data transmission request including information indicating the file name and the directory name of the image file selected by the user to the camera 10. The camera 10 reads the image file stored in the location specified by the image data transmission request received from the mobile device 100 from the external memory 180, and transmits the read image file data to the mobile device 100. The mobile device 100 stores the data of the image file 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 mobile 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 to transmit the list information to the mobile device 100 also increases. However, according to the camera system 5, the time required to transmit the list information can be omitted. . Further, the communication amount for transmitting the list information to the mobile device 100 can be reduced.

  Further, according to the camera 10, since the transmission reservation information is recorded in the external memory 180, the user can select an image file at a desired timing. For example, after specifying an image file to be transmitted to the mobile device 100, the user can add a new image file obtained by newly photographing with the camera 10 to the transmission reservation list and record it. . In this way, the specified image files can be transmitted collectively with the shooting operation interposed between the operations of specifying the image files. Further, in addition to shooting during the operation of designating an image file, the operation of changing the operation settings of the camera 10 and the operation of editing the image data are interposed between the operation of designating the image file and the designated image file. They can be sent all at once. Therefore, even if another operation needs to be performed while the image file is specified, there is no need to perform the image file specification operation again from the beginning after performing the operation.

  FIG. 2 shows an example of a system configuration of the camera 10 together with an 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 is detachable 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 point 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 contacts 121 and the camera mount contacts 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 advanced position in the subject light flux centered on the optical axis of the lens group 122 and a retracted position 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 at the position where it has advanced into the subject light beam, the sub mirror 146 is also at the position where it has advanced into the subject light beam. When the release button is pressed, the mirror unit is raised 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 returns to the advanced position.

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

  A part of the subject light beam transmitted 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 has a plurality of photoelectric conversion element rows that receive a subject light beam. The photoelectric conversion element array outputs a signal with the same phase when in a focused state, and outputs a signal with a phase shift when in a front focus state or a rear focus state. The phase shift amount corresponds to the shift amount 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, based on the focus state detected from the phase difference signal, the target position of the focus lens included in the lens group 122 is determined by the camera MPU 140, and the position of the focus lens is controlled by controlling the lens MPU 123 toward the determined target position. Is done. Specifically, the lens MPU 123 controls a lens driving unit 124 including a focus lens motor, for example, to move a focus lens included in the lens group 122. As described above, when the main mirror 145 is lowered to the advanced position and the mirror unit is at the advanced position, the focus state of the lens group 122 is detected by the phase difference detection method, and the focus is adjusted. In the AF unit 142, photoelectric conversion elements are provided at a plurality of positions respectively corresponding to the plurality of focus adjustment positions so as to adjust the focus state at each of the plurality of focus adjustment positions within the imaging range of the imaging element 132.

  The photometry element 144 is an example of a photometry unit that performs photometry of 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 device 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, based on luminance information detected by a photoelectric conversion element located in a range corresponding to the recording range, among a plurality of photoelectric conversion elements included in the photometric element 144, The AE evaluation value may be calculated.

  When the main mirror 145 retreats from the subject light beam, the sub mirror 146 retreats 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, for example, a mechanical shutter. When the mirror unit is at the retracted position and the focal plane shutter 143 is in the open state, the subject light flux transmitted 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 the optical path of subject light incident on the image sensor 132.

  The imaging device 132 functions as an imaging unit. The image sensor 132 captures an image of a subject using a subject light beam that has passed through the lens group 122. As the imaging device 132, for example, a solid-state imaging device such as a CMOS sensor or a CCD sensor can be exemplified. The imaging element 132 has a plurality of photoelectric conversion elements that receive a 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 clamp 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 imaging device 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 an image processing function are integrated. The ASIC 135 uses at least a part of the memory area of the RAM 136 as an example of the 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 by the ASIC 135 include noise reduction processing, defective pixel correction, white balance adjustment, color interpolation processing, color correction, gamma correction, contour enhancement processing, image data compression processing, and the like.

  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 the imaging device 132 taking images continuously is sequentially stored in the buffer area as image data of continuous still images or image data of each image constituting a moving image. The RAM 136 also functions as a frame memory that temporarily stores a frame when the ASIC 135 processes moving image data.

  Examples of the 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). The image processing in the ASIC 135 includes a process of detecting a contrast amount for the AF process. Specifically, the ASIC 135 detects a contrast amount from the image data and supplies the detected contrast amount to the camera MPU 140. For example, the ASIC 135 detects a contrast amount from each of a plurality of pieces of image data obtained by imaging with the focus lens positioned at a different position 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 contrast amount, 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 moved up and is at the retracted position, the focus state of the lens group 122 is detected by the contrast detection method, and focus adjustment is performed. In this manner, the camera MPU 140 adjusts the focus 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 image data in a standardized image format. For example, the ASIC 135 performs a compression process to generate still image data obtained by encoding still image data in an encoding format conforming to a standard such as JPEG. In addition, the ASIC 135 converts the plurality of frames into QuickTime, A compression process for generating moving image data encoded by an encoding method conforming to standards such as H.264, MPEG2, and Motion JPEG is performed. Image data such as recording still image data and moving image data generated by the ASIC 135 is transferred from the RAM 136 to the external memory 180 via the recording medium IF 152.

  The external memory 180 is mounted on the recording medium connector 151. The external memory 180 is detachable from the camera body 130. The external memory 180 is an example of a non-volatile recording medium. The external memory 180 is composed of, for example, a semiconductor memory such as a flash memory. 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 image data for display in parallel with generation of image data for recording. 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 display image data is converted into an analog signal under the control of the display control unit 137 and displayed on a display unit 138 such as a liquid crystal display. In addition to the image display based on the image data obtained by the imaging, various menu items related to various settings of the camera 10 are also displayed on the display unit 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 communicably connected via the external device connector 153. Note that the image data stored in the RAM 136 may be image data transferred from the external memory 180 to the RAM 136 via the recording medium IF 152, generated by the ASIC 135 in accordance with the imaging operation of the imaging device 132, and stored in the RAM 136. Image data.

  Further, 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 from the portable device 100 an image data transmission request for transmitting image data. When the wireless communication module 150 receives a request to transmit image data from the mobile device 100, the camera MPU 140 reads out image data from the external memory 180 to the RAM 136 through the recording medium IF 152, and reads out the image data read out to the RAM 136. Is wirelessly transmitted from the wireless communication module 150 to the portable device 100.

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

  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 integrally mounted on 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 according to the operation. For example, the camera MPU 140 controls each unit of the camera 10 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 that when an input member mounted as a touch panel is operated, an operation according to the menu item displayed on the display unit 138 and the operation content is performed. As described above, 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 directly or indirectly controlled by the camera MPU 140 and the ASIC 135, including the control described above. Parameters such as constants and variables necessary for the operation of the camera 10, programs, and the like are stored in the system memory 139. The system memory 139 is a non-volatile memory that can be electrically erased and stored, and includes, for example, a flash ROM, an EEPROM, and the like. The system memory 139 stores parameters, programs, and the like so as not to be lost even when the camera 10 is not operating. The parameters, programs, and the like stored in the system memory 139 are developed 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 mutually connected by 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 receive power supply from a power supply 190 via a power supply circuit 192. Examples of the power supply 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 supply, and the like. A secondary battery is an example of a battery, and a battery includes a primary battery that cannot be substantially charged. The camera MPU 140 controls the power supply from the power supply 190 to each part 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 a user. The instruction obtaining unit 330 obtains an instruction to specify image data from a user based on the operation of the operation input unit 141.

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

  The transmission reservation list transmitting 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 reads the read transmission list. The data of the reservation list is transmitted to the portable device 100.

  The image data transmitting unit 350 transmits image data to the mobile device 100 when receiving a transmission request for image data specified based on the transmission reservation list from the mobile device 100. When 150 receives the image data transmission request transmitted from portable device 100, it controls recording medium IF 152 to read an image file from external memory 180, and transmits the read image file data to portable device 100.

  The transmission reservation list recording unit 300 stores the transmission reservation list including the first information for specifying the first image data when the instruction obtaining unit 330 obtains the first instruction to specify the first image data from the user. It is recorded in the external memory 180. Then, when the instruction acquisition unit 330 acquires from the user 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 transmitting unit 350 transmits the first image data and the second image data to the portable device 100 when the portable device 100 requests to designate and transmit the first image data and the second image data based on the transmission reservation list. Transmit to the 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 is making a transmission reservation.

  Each time the image data transmitting unit 350 transmits the image data to the mobile device 100, the reception completion notification obtaining unit 320 obtains from the mobile device 100 a reception completion notification indicating that the mobile device 100 has completed the reception of the image data. 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 the information specifying the image data notified from the mobile device 100 from the transmission reservation list. As described above, the transmission reservation list updating unit 310 transmits the image data specified by the transmission reservation list recorded in the external memory 180 to the mobile device 100 every time the image data transmission unit 350 transmits the image data to the mobile 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 according to an image reproduction instruction acquired from the user. In this case, the camera MPU 140 controls the ASIC 135 to change the image data of the image displayed on the display unit 138 when the transmission reservation list includes information for specifying the image data of the image displayed on the display unit 138. Is displayed on the display unit 138 together with the image indicating that the image data is to be transmitted to the other device.

  FIG. 4 illustrates an example of a 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 mobile 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 controls the entire control of the mobile device 100. The system memory 230 is a non-volatile memory that can be electrically erased and stored, and includes, for example, a flash ROM. The system memory 230 stores control parameters such as constants and variables required for the operation of the mobile device 100, programs, and the like so that the parameters are not lost even when the mobile device 100 is not operating. The 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 for controlling each unit of the mobile device 100. An SDRAM or the like can be applied as the RAM 220.

  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. As the display unit 280, a display device such as a liquid crystal display can be used. 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 and receives various data to and from the camera 10.

  The mobile device MPU 210 has 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 requesting unit 420 transmits a request for transmitting an image file to the camera 10 based on the transmission reservation list acquired from the camera 10. Specifically, the image data requesting unit 420 controls the wireless module 270 to transmit an image data transmission request to the camera 10. The image data requesting unit 420 transmits an image data transmission request including the storage information included in the transmission reservation list to the camera 10. For this reason, the camera 10 may use the image file stored in the location requested by the image data transmission request as the portable device 100.

  Note that the image information requesting unit 430, when unable to acquire a transmission reservation list including information for specifying image data specified by the user from the camera 10, stores the image information of one or more image data stored in the camera 10. And the information for 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.

  Selection control section 440 causes display section 280 to display an image based on the image information acquired from camera 10, and allows the user to select image data to be transmitted from camera 10 to portable device 100. Selection control section 440 determines which image data the user has designated based on the display position of the image and the user's operation on operation input section 250. When the transmission reservation list including the information for specifying the image data specified by the user cannot be acquired from the camera 10, the image data requesting unit 420 performs, based on the information for specifying the image data selected by the selection control unit 440, The transmission request of the image data selected by the selection control unit 440 is transmitted to the camera 10. As described above, the image data requesting 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 mobile device 100.

  FIG. 5 schematically shows an example of 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 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 a transmission target image file. To indicate 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 specified as the transmission target image file. Show. The storage information recorded in the reservation number 3 of the transmission reservation list indicates that the file named “DSC_0005.JPG” in the directory named “100NK” in the external memory 180 is specified as the transmission target image file. Show.

  In the present embodiment, the transmission reservation list is stored in a root directory, which is a first-level 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 a directory “100NK”. The transmission reservation list may be stored in a directory in which the image file is stored or in a directory lower in the hierarchy than the directory. When the image file is stored in a single specific directory, the storage information of the transmission reservation list does not need to include the directory name.

  With reference to FIG. 6 to FIG. 11, a process when a user adds or deletes an image file as a transmission target image file will be described using a screen. In the initial state, a description will be given assuming that the transmission reservation list shown in FIG. 5 is stored.

  FIG. 6 shows an example of an image reproduction screen 600. On the reproduction screen 600, an image based on the image data recorded in the external memory 180 is displayed on the display unit 138 in the reproduction mode. The reproduction screen 600 shows a state in which an image based on one image file “DSC_0006.JPG” selected by the user 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 an image editing menu on the operation input unit 141 while the reproduction screen 600 is displayed, the camera MPU 140 causes the display unit 138 to display a menu screen 700 shown in FIG.

  FIG. 7 is a menu screen 700 for one currently selected image file “DSC_0006.JPG”. The menu screen 700 includes a selection item 710 of “designate / cancel transmission to external device”. When the selection input operation is performed by the operation of the operation input unit 141 while the selection item 710 is selected, the instruction acquisition unit 330 of the camera MPU 140 determines that the user has designated “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. Thereby, the storage information of the four image files is written in the transmission reservation list. As described above, the user performs a predetermined operation on the operation input unit 141 while the menu screen 700 is displayed, thereby adding the image file “DSC_0006.JPG” as the transmission target image file. be able to.

  FIG. 8 shows an example of the playback screen 800 after “DSC_0006.JPG” has been specified as the transmission target image file. The reproduction screen 800 includes a mark 810 indicating a state specified as a transmission target image file. The ASIC 135 superimposes the mark 810 on an image based on the image file “DSC_0006.JPG”.

  When the release button is half-pressed while the playback screen 800 is displayed, the camera 10 transitions from the playback mode to the shooting standby mode. However, the transmission reservation list includes a state in which information of four image files is written. Will be maintained. When the operation for setting the operation of the camera 10 is performed while the playback screen 800 is displayed, the camera 10 transitions from the playback mode to the setting mode. However, the information of the four image files is included in the transmission reservation list. The written state is maintained. Therefore, even if the camera 10 transitions to another operation mode while the image file to be transmitted is being selected, the information of the transmission reservation list is not lost.

  When the menu screen 700 of FIG. 7 is displayed from the state where the reproduction screen 800 is displayed, and the selection item 710 of “designate / cancel transmission to external device” is selected, the transmission reservation list recording unit 300 The information of “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.

  6 to 8, the processing in the reproduction mode has been described. The same processing as the processing described in relation to the main playback screen can also be applied to a display screen in which an image captured on the display unit 138 after image capturing is displayed for a certain period of time in the image capturing mode.

  Next, a case in which 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 a process 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.

  The menu screen 900 includes a selection item 910 of “designate / cancel transmission to external device”. When the selection confirmation operation is performed in a state where the selection item 910 is 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 shown in FIG.

  FIG. 10 is an example of a specification screen 1000 for specifying 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 displaying the designation screen 1000, the camera MPU 140 controls the ASIC 135 to superimpose on the thumbnail image 1002 corresponding to “DSC_0002.JPG” to indicate that the corresponding image file is designated as the transmission target image file. Mark 1012 is displayed. Similarly, camera MPU 140 superimposes on thumbnail image 1003 corresponding to “DSC_0003.JPG” and displays mark 1013 indicating that the corresponding image file has been designated as the transmission target image file. Further, the camera MPU 140 superimposes the thumbnail image 1005 corresponding to “DSC_0005.JPG” and displays a mark 1015 indicating that the corresponding image file is designated as the transmission target image file.

  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. 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 where 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 causes the user to designate “DSC_0006.JPG” as the transmission target image file. Judge that you have done. 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. Thereby, the storage information of the four image files is written in the transmission reservation list.

  FIG. 11 shows an example of the designation screen 1100 after “DSC_0006.JPG” has been 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 displays a mark 1016 that is superimposed on the thumbnail image 1006 and indicates that the corresponding image file is specified as the transmission target image file.

  Subsequently, when an operation of moving the cursor 1020 is performed and, for example, a selection confirmation operation is performed in a state where the thumbnail image 1001 corresponding to “DSC_0001.JPG” is selected, the instruction acquisition unit 330 of the camera MPU 140 displays DSC_0001.JPG "is specified 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, the transmission reservation list is in a state where the storage information of the five image files is written. In this way, the user can continuously specify the transmission target image file.

  Note that, when the selection confirmation operation is performed while the designation screen 1000 is displayed, the transmission reservation list recording unit 300 deletes the information of “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. The portable device MPU 210 causes the display unit 280 to display an image acquisition screen 1200 when an operation for instructing acquisition of image data from the camera 10 is performed on the operation input unit 250. The image acquisition screen 1200 includes a button 1210 selected when the camera 10 captures an image file to acquire an image file, and a button 1220 selected when acquiring an image file currently stored in the camera 10.

  When the button 1210 is selected on the image acquisition screen 1200 when the mobile device 100 and the camera 10 are wirelessly connected, the mobile device MPU 210 causes the wireless module 270 to transmit a shooting instruction to the camera 10. When the camera 10 receives the imaging instruction, the camera MPU 140 causes the imaging operation to be performed, stores the image file obtained by the imaging operation in the external memory 180, and transmits the image file data from the wireless communication module 150 to the mobile device 100. Send. When the wireless module 270 receives the data of the image file, the mobile 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 button 1220 is selected on the image acquisition screen 1200 when the mobile device 100 and the camera 10 are wirelessly connected, the mobile device MPU 210 transmits a transmission reservation list request from the wireless module 270 to the camera 10. 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. Upon acquiring the transmission reservation list, the mobile device MPU 210 sequentially transmits image data transmission requests to the camera 10 according to the transmission list. The camera 10 transmits the data of the image file from the wireless communication module 150 to the portable device 100 according to the image data transmission request. When receiving the data of the image file by the wireless module 270, the mobile device MPU 210 stores the image file in the recording medium 240 based on the received data.

  13 and 14, the operation of the mobile device 100 will be described using a flow. 15 to 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 and reception of a transmission reservation list and image data between the mobile device 100 and the camera 10. This flow shows the 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 unit of the mobile device 100 mainly by the mobile device MPU 210.

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

  In step S1304, mobile device MPU 210 determines an operation on operation input unit 250. Here, an operation for instructing termination of the mobile 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 to instruct acquisition of image data from the camera 10, the process advances 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 termination of the mobile device-side application program, the process proceeds to step S1318.

  In step S1306, portable device MPU 210 displays image acquisition screen 1200 illustrated in FIG. 12 on 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, and if the “take” button 1210 is selected, the process proceeds to step S1314.

  In step S1310, a process of acquiring an image file from the camera 10 is performed. The processing in step S1310 will be described with reference to FIG. Upon completion of the process in step S1310, 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, a process of transmitting a photographing instruction to the camera 10 and acquiring and displaying an image file photographed by the camera 10 is performed as described with reference to FIG. The description of the details of this process is omitted. Upon completion of the process in the step S1314, the process proceeds to a step S1304.

  In step S1316, a process according to the operation determined in step S1304 is performed, and the process proceeds to step S1304. In step S1318, an operation for ending the application program is performed, and the present flow ends.

  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 process of step S1310 in FIG. Here, it is assumed that an application-level connection has been established with a camera-side application program that operates 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, portable device MPU 210 determines whether or not the model of camera 10 is a model having a function of recording a transmission reservation list.

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

  In step S1404, the mobile device MPU 210 transmits a transmission reservation list request from the wireless module 270. Subsequently, it is determined whether there is a transmission reservation list including the image file information (step S1406). For example, when a notification that the transmission reservation list including the image file information is not present in the camera 10 is received from the camera 10, the determination in step S1406 is N. If 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 the 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 steps S1410 to S1420, image file data is acquired from the camera 10 according to the received transmission reservation list.

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

  Subsequently, in step S1414, it is determined whether the image file data has been received. If the image file data has not been 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 for which no reception processing has been performed, and the reception processing of this image file may be retried up to a predetermined number of times.

  If the data of the image file has been 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 to the effect that 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 processing has been completed for all the image files, the operation of this flow ends. 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 for which reception processing has been performed so far are set as image files to be subjected to the next reception processing. One image file is selected from.

  In step S1432, a thumbnail information request for transmitting thumbnail information is transmitted to camera 10, and subsequently, thumbnail information is received from camera 10 (step S1434). The thumbnail information includes thumbnail image data and storage information of an image file 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 is caused to select a thumbnail image corresponding to an image file to be acquired from the camera 10 from among 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). Information similar to the information stored in the transmission reservation list is stored in the reception target list.

  Subsequently, in step S1442, data of an image file is acquired from the camera 10 according to the reception target list. Since the same processing as the processing from step S1410 to step S1420 can be applied to the processing in step S1442, the description is 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 unit of the camera 10 mainly by the camera MPU 140.

  In step S1502, the camera MPU 140 starts initialization of the camera 10. For example, the camera MPU 140 develops various parameters for controlling the camera 10 from the system memory 139 to the RAM 136. The camera MPU 140 performs an initial setting of the camera 10 based on, for example, various developed system parameters. For example, default imaging conditions are set based on system parameters related to imaging conditions. When the operation of the wireless communication module 150 is set to ON, a process 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 and the like to display the contents set in the initial setting. For example, the camera MPU 140 causes the display unit 138 to display information such as the determined default imaging conditions in various formats such as icon display. Here, the camera 10 transitions to a shooting standby mode in which a shooting instruction can be accepted through a release button or a moving image recording button.

  Subsequently, in step S1506, the generated event is specified. Here, as events, a setting event generated by operating a setting button, a shooting event generated by pressing a release button or a moving image recording button, a playback event generated by pressing a playback menu through a menu button, and a playback event generated by pressing a playback menu through a menu button An image editing event and a power-off event that occur when the image editing menu is selected will be described.

  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.

  If a setting event has occurred, the mode transits to the setting mode and performs setting processing according to the user operation (step S1510). Examples of the setting process include a process of setting an imaging condition and a process of setting a recording condition of image data. Further, as the setting process, a process of 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, a process for starting up 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 pressing operation of the release button is detected, and transitions to a 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 or moving image capturing operation, image processing on still image or moving image image data, and processing for 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 switched 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 a thumbnail based on image data recorded in the external memory 180, a process of reproducing image data selected by a user, and the like. The processing in step S1514 will be described with reference to FIG. The operation in the reproduction mode ends when a predetermined operation such as a press-down operation of the release button is detected, and transitions to the shooting standby mode.

  If it is determined in step S1506 that an image editing event has occurred, the mode transits to the image editing mode and performs an image editing operation according to the user operation (step S1514). As a part of the image editing operation, the operation related to the specification 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 pressing operation of the release button is detected, and the operation transits to the shooting standby mode.

  When the processing of step S1510, step S1512, step S1514, and step S1516 ends, the processing moves to step S1506. If it is determined in step S1506 that a power-off event has occurred, a predetermined end process for stopping the operation of the camera 10 is performed (step S1522), and this flow ends.

  FIG. 16 shows an example of an 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. Next, it is determined whether the current image display mode is the thumbnail display mode or the single image display mode (step S1604). In the case of 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 case of the thumbnail display mode, a predetermined number of thumbnail images including the thumbnail image corresponding to the currently selected one 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 displaying an image corresponding to the image file specified as the transmission target image file, a mark to that effect is displayed so as to be superimposed on the image.

  In step S1610, a user operation is determined. Here, as the user's operation, an operation to instruct the display of the image editing menu, an operation to instruct to delete the image file, an operation to instruct to change the currently selected image file, and an operation to instruct the end of the playback mode Is 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. Subsequently, the menu operation of the user is determined (step S1614). If the menu operation is an operation of selecting “designation / cancellation of transmission to external device”, the transmission reservation list is changed (step S1616).

  In step S1616, if the currently selected image file is not specified 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 specified 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 the image file 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 “designation / cancellation of transmission to an external device”, a process corresponding 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 to instruct to delete 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 specified as the image file to be transmitted (step S1634). If the image file to be deleted is specified as the image file to be transmitted, the transmission reservation list is set. , The storage information of the image file is deleted (step S1636), and the process proceeds to step S1638. If the image file to be deleted is not specified as the transmission target image file, the process proceeds to step S1638. In step S1638, the currently selected image file is changed to the next image file, and the flow advances to step S1610.

  If it is determined in step S1610 that an operation to change the currently selected image file has been performed, a display for changing the current image file is displayed (step S1642), and the process proceeds to step S1610. In step S1642, the position of the cursor 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 reproduction mode has been performed, the present 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 launch of the camera-side application program is completed. This flow is executed by mainly operating the camera MPU 140.

  In step S1702, the camera MPU 140 specifies the event that has occurred. Here, as the events, a transmission reservation list request event generated in response to the reception of the transmission reservation list request, a thumbnail information request event generated in response to the reception of the thumbnail information request, and an image data generated in response to the reception of the 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 the transmission reservation list request event has occurred, it is determined whether storage information of one or more image files is stored in the transmission reservation list (step S1704). If the storage information of one or more image files is stored in the transmission reservation list, the transmission reservation list is transmitted to the portable 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 fact that there is no transmission reservation list including the image file information in the camera 10 is transmitted to the portable device 100 (step S1708), and the process proceeds to step S1702.

  If it is determined in step S1702 that a thumbnail information request event has occurred, 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 for a notification that the image file has been received from the camera 10 (step S1724). When the notification that the image file has been received is received, the corresponding storage information is deleted from the transmission reservation list (step S1726), and the process proceeds to step S1702. If the notification that the image file has been received is not received, the process proceeds to step S1702 without deleting the corresponding storage 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 transmit and receive 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. 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 portable 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 the external memory 180 that is detachable from the camera body 130. The external memory 180 is an example of a non-volatile recording medium. The recording medium for storing the image file and the transmission reservation list need not be removable from the camera body 130. The image file and the transmission reservation list may be stored in a nonvolatile recording medium built in the camera body 130. Although the transmission reservation list is preferably stored on a recording medium that stores the image file, the transmission reservation list may be stored on a recording medium other than the recording medium that stores the image file. When an image file is stored in a removable recording medium such as the external memory 180, it is preferable that at least the image file and the transmission reservation list are stored 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 easier to send.

  In the present embodiment, the transmission reservation list is stored in the external memory 180 as a file. However, it may be stored in an image file specified 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.
