<First Embodiment>
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an external perspective view of a digital camera and an adapter.

  A digital camera 100 as an example of an imaging device and an adapter (camera adapter device) 105 are connected by an interface cable 106. The interface cable 106 may be a USB cable, for example. A connector that can be directly connected to the interface cable 106 may be used.

  A PC (personal computer) is used as an example of the external device. The adapter 105 and the PC are connected via a network. The network may be connected by wire or wirelessly.

  The digital camera 100 includes a shutter button 101, a cross key 102, and an enter button 103, which are included in an operation unit 206 (FIG. 2) described later. Moreover, the display part 104 which displays a captured image and functions as EVF (electronic viewfinder) is provided.

  FIG. 2 is a block diagram showing a hardware configuration of the digital camera in FIG.

  In FIG. 2, the digital camera 100 includes a system bus 210 and the following elements connected to the system bus 210.

  The CPU 201 controls the entire digital camera 100 by executing a control program stored in the ROM 202. The ROM 202 is a non-volatile memory that holds the above-described control program and the like.

  A RAM 203 is a volatile memory used as a work area when the CPU 201 executes a control program. The RAM 203 is also used as an area for temporarily buffering the captured digital image data before recording it in the storage medium 208.

  The imaging unit 204 includes an optical lens, a CCD, an A / D converter, and the like, converts light incident from the optical lens into a digital electrical signal, and stores the digital electrical signal in the RAM 203.

  The signal processing unit 205 performs signal processing such as JPEG encoding or MPEG encoding on the digital electrical signal stored in the RAM 203 by the imaging unit 204 to generate digital image data. The generated digital image data is recorded on the storage medium 208.

  At the time of image reproduction, the signal processing unit 205 reproduces (decodes) the digital image data recorded on the storage medium 208. The signal processing unit 205 is generally realized by using a dedicated hardware circuit, but may be realized by the CPU 201 executing software (program) held in the ROM 202.

  The operation unit 206 includes a power button, a shutter button, and the like. A user of the digital camera 100 can give an instruction to the digital camera 100 via the operation unit 206.

  The display unit 104 is for displaying an image at the time of reproducing digital image data, and includes a TFT LCD or the like. The display unit 104 can also be used as an electronic viewfinder that sequentially displays digital image data captured by the imaging unit 204.

  The storage medium control unit 207 controls a storage medium 208 described below. The storage medium 208 is for recording digital image data. For example, a digital video cassette, a DVD-R, a compact flash (registered trademark), a hard disk, or the like can be used.

  The communication I / F 209 is an interface for communicating with the camera communication I / F 306 (FIG. 3) of the adapter 105 in this embodiment, and is, for example, USB, IEEE 1394, or the like.

  FIG. 3 is a block diagram showing a hardware configuration of the adapter in FIG.

  In FIG. 3, the adapter 105 includes a system bus 308 and the following elements connected to the system bus 308.

  The CPU 301 controls the entire adapter 105 by executing a control program stored in the ROM 302. It is also possible to perform various image processing and compression processing on image data.

  The ROM 302 is a non-volatile memory that holds the above-described control program and the like. In addition, an HTML document created in advance such as a main screen as an HTTP server is held.

  A RAM 303 is a volatile memory used as a work area when the CPU 301 executes a control program. The RAM 303 is also used as an area for temporarily buffering digital image data transferred from the digital camera 100 to the camera communication I / F 306 of the adapter 105 connected via the communication I / F 209 of the digital camera. Thereafter, the image data is transferred to the external device by the network communication I / F 304. The RAM 303 is also used as an area for buffering the HTML document created by the HTML document creation unit 307.

  The network communication I / F 304 is an interface for communicating with an external device, and is an Ethernet (registered trademark), a wireless LAN, or the like. Controls network communication devices and controls data transmission / reception with external devices.

  The HTTP server 305 communicates with an external apparatus according to the HTTP protocol, and exchanges HTML documents. A browser is stored in advance in a storage device (not shown) of the external device, and the external device can communicate with the HTTP server 305 by using the function of the browser. The camera communication I / F 306 is an interface for communicating with the camera communication I / F 209 and is, for example, USB, IEEE 1394, or the like.

  In communication between the browser function of the external device and the HTTP server 305, the HTML document creation unit 307 generates a signal exchanged between the browser of the external device and the HTTP server 305 as an HTML document. Examples of the signal include digital image data captured by the imaging unit 204 of the digital camera 100, a reduced image of the digital image data, setting data of the digital camera 100, control data of the digital camera, and the like.

  Next, the processing flow of the HTTP server 305 will be described.

  FIG. 4 is a flowchart showing a processing procedure from when the digital camera is turned on until the image browsing display screen is displayed on the browser of the external device.

  When the digital camera 100 is turned on, after confirming that the adapter 105 is connected, the digital camera 100 performs each initialization, and transmits an activation request for the HTTP server 305 to the adapter 105 (step S100).

  Upon receiving the HTTP server 305 activation request, the adapter 105 activates the HTTP server 305 and waits for reception from a client of an external device (PC) (step S101).

  The user of the external device designates the IP address of the HTTP server 305 on the browser using a pointing device such as a keyboard or a mouse. The external device transmits a connection request to the adapter 105 (step S102).

  Upon receiving the connection request, the adapter 105 confirms the user name and password transmitted from the external device, and if it is a legitimate user, transmits an HTML document describing information on the main screen to the external device (step). S103).

  The external device that has received the HTML document displays the main screen 400 based on the received HTML document on the display unit of the external device (step S104).

  FIG. 5 is a diagram showing an example of the main screen of the external device displayed by the browser function.

  The main screen 400 according to the present embodiment includes a button “Viewer” 401 for requesting image browsing and a button “Capture” 402 for performing camera control. When the button “Viewer” 401 for requesting image browsing display is pressed by the client of the external apparatus, an HTML document instructing image browsing display is transmitted to the HTTP server 305 (step S105).

  When the adapter 105 interprets the received HTML document (step S106) and interprets it as a request for instructing image browsing display, the adapter 105 requests the digital camera 100 for a reduced image necessary for browsing (step S107).

  The digital camera 100 that has received the request for the reduced image reads the reduced image of the designated digital image data from the storage medium 208 and transmits it to the adapter 105 (step S108).

  The adapter 105 repeats the processing of step S107 and step S108 for the number of sheets that can be displayed on the browser (step S109). If the number of digital image data recorded on the recording medium 208 is less than the number that can be displayed, this process is repeated for the number of recorded digital image data.

  When the reduced image is received from the digital camera 100, the HTML document creation unit 307 creates an HTML document describing the link between the reduced image and the digital image data (step S110). The created HTML document is transmitted to the external device (step S111).

  The browser of the external device that has received the HTML document displays an image browsing screen (step S112).

  FIG. 6 is a diagram illustrating an example of an image browsing screen of the external device.

  On the screen display (image browsing screen) 500, reduced images 501 are displayed side by side. The reduced image 501 describes the link destination of each display image and digital image data in the HTML document. The user of the external apparatus can select the displayed reduced image by operating the pointing device and request digital image data with higher resolution.

  FIG. 7 is a flowchart showing a processing procedure until an image is displayed in response to a reduced image selected by the browser of the external device on the image browsing screen of the external device.

  In this embodiment, when an image that cannot be displayed on the browser is selected, the user is notified that the image cannot be displayed.

  In the present embodiment, whether or not an image can be displayed by a browser depends on the file format. The ROM 302 of the adapter 105 stores in advance a file format that can be displayed by a browser and a file format that cannot be displayed.

  For example, the browser in the present embodiment can display digital image data compressed by the JPEG compression method. Therefore, image data with a file extension “JPG” is recorded in the ROM 302 as image data that can be displayed by a browser. Further, so-called RAW image data for reproducing digital data obtained by imaging as it is cannot be displayed by a browser. Accordingly, data whose file extension indicates RAW image data, for example, image data whose extension is “RAW” or “CRW” is stored in the ROM 302 as image data that cannot be displayed. Hereinafter, an image file having an extension “RAW” is used as an example of a file format including image data that cannot be displayed.

  In the following description, it is assumed that the external device that has received the HTML document displays the image browsing screen in step S112.

  When a reduced image is selected (clicked) from the image browsing screen by a user operation, the external apparatus transmits an acquisition request for acquiring digital image data corresponding to the selected reduced image to the HTTP server 305 ( Step S200). The acquisition request includes information indicating the correspondence between the reduced image and the digital image data stored in the digital camera 100, such as a file name. This acquisition request is described in an HTML document and transmitted from the external device to the adapter 105.

  When the adapter 105 receives the digital image data acquisition request, the adapter 105 interprets the received HTML document and determines the digital image data to be transmitted (step S201).

  Next, the adapter 105 determines whether the digital image data determined in step S201 can be displayed by the browser (step S202). In this embodiment, the extension of a file containing digital image data is referenced to determine whether or not display is possible. As described above, which extensions can be displayed is recorded in the ROM 302 in advance.

  If it is determined in step S202 that display is possible, the adapter 105 transmits a digital image data acquisition request (step S203) to the digital camera 100.

  The digital camera 100 reads out the digital image data designated by the acquisition request from the storage medium 208 and transmits it to the adapter 105 (step S204).

  If it is determined in step S202 that display is impossible, the adapter 105 sets an image for notifying the user that display cannot be performed (hereinafter referred to as “warning image”) as an image to be displayed on the external apparatus (step S205). The warning image is stored in advance in the ROM 302 of the adapter 105, and the warning image stored in this step is read out.

  The adapter 105 creates an HTML document in the HTML document creation unit 307 using the digital image data obtained by the processes in steps S204 and S205 (step S206), and transmits the created HTML document to the external device. (Step S207). That is, if it is determined in step S202 that display is possible, the adapter 105 creates an HTML document for displaying the digital image data received from the digital camera 100. If it is determined in step S202 that it cannot be displayed, an HTML document for displaying a warning image is created.

  The external device displays the received digital image data (step S208).

  FIG. 9 is a diagram showing an example of a screen displayed on the external device by the browser function when it is determined that display is impossible in step S202 of FIG. Specifically, in FIG. It is an example of a screen displayed when “RAW” is selected.

  Reference numeral 600 denotes a warning image. In this embodiment, an image file whose file extension is “RAW” cannot be displayed by a browser. Therefore, the adapter 105 determines that display is impossible and transmits a warning image to the external device. In addition to the fact that digital image data cannot be displayed on the warning image, it is displayed that the external device can acquire and store the digital image data. In the HTML document showing the screen of FIG. 9, link information to the warning image is described as a display target. In addition, the storage destination of the digital image data is described as link information as a link destination to be stored when the image 600 is stored in an external device. That is, in an HTML document, information indicating an image to be displayed is different from information indicating an image to be stored.

  When an instruction to save an image is given by a user operation while the image 600 is displayed, a request to save digital image data is transmitted from the external device to the HTTP server 305. The adapter 105 requests the digital camera 100 to acquire digital image data, and IMG_0001. RAW digital image data is received. Then, the digital image data is transmitted to the external device.

  As described above, when there is image data that cannot be displayed on the external device, the adapter 105 according to the present embodiment controls the external device to display a warning image for notifying that effect. Do. Furthermore, it is notified that the warning image cannot be displayed but can be acquired.

<Second Embodiment>
This embodiment is characterized in that when an image that cannot be displayed on an external device is selected using a browser function, digital image data that cannot be displayed is analyzed and display image data that can be displayed is generated.

  Note that the processing in this embodiment has many parts in common with the first embodiment. Therefore, description of parts common to the first embodiment is omitted, and parts unique to the present embodiment are mainly described.

  In the description of the processing of FIG. 8, it is assumed that a file having the extension “JPG” can be displayed by the browser, and an image file having the extension “RAW” cannot be displayed.

  Steps S112, S300, and S301 are the same as steps S112, S200, and S201 in FIG. Hereinafter, step S302 will be described.

  The adapter 105 transmits an acquisition request for acquiring the digital image data determined in step S301 to the digital camera 100 (step S302). The digital camera 100 reads out the digital image data requested from the adapter 105 from the storage medium 208 and transmits it to the adapter 105 (step S303).

  The adapter 105 determines whether the digital image data interpreted in step S301 can be displayed on the browser of the external device (step S304). As in the first embodiment, the determination in this step is performed by referring to the file extension.

  If it is determined in step S304 that display is possible, the adapter 105 sets the digital image data acquired from the digital camera 100 as image data to be transmitted to the external device and displayed. If it is determined in step S304 that display is impossible, the adapter 105 analyzes the digital image data acquired from the digital camera 100, and generates a display image in a format that can be displayed by the browser of the external device. For example, a new image based on the JPEG compression format is generated based on the RAW image data, and is set as image data to be transmitted to an external device and displayed (step S305). Some files include a display image (for example, an image compressed by the JPEG method) in the file. In that case, a display image to be transmitted to the external device may be generated based on the display image included in the file.

  The adapter 105 creates an HTML document in the HTML document creation unit 307 using the image data to be sent (step S306), and sends the created HTML document to the external device (step S307). The external device displays the received image (step S308).

  FIG. 10 is a diagram showing an example of a screen displayed on the external device by the browser function when it is determined in step S305 in FIG. 8 that display is impossible. Specifically, it is an example of a screen displayed when the user selects “IMG — 0001.RAW” in FIG.

  The browser of the external device in the present embodiment cannot display an image file with the extension “RAW”, but can display an image as shown in FIG. 10 because a display image is transmitted from the adapter 105. It becomes. That is, the user can display and save an image without being aware of whether the digital image data can be displayed by the browser.

<Third Embodiment>
As described in the second embodiment, some file formats include a display image (for example, an image compressed by the JPEG method) in the file. Whether or not a display image is included in the file may depend on the function of the photographed digital camera.

  Therefore, in the present embodiment, when image data that cannot be displayed by the browser of the external device is requested, whether the warning image is displayed or the display image is newly generated and displayed is set as the ID of the photographed digital camera. It was set as the structure selected based on.

  Note that the processing in this embodiment has many parts in common with the first and second embodiments. Therefore, description of parts common to the first and second embodiments will be omitted, and parts unique to the present embodiment will be mainly described.

  FIG. 11 is a flowchart of processing in the present embodiment.

  Steps S112 and S400 to S404 are the same as steps S112 and S300 to S304 in FIG. Hereinafter, the process after step S405 will be described.

  The adapter 105 requests the digital camera 100 for the ID of the digital camera 100 and receives it. The ROM 302 of the adapter 105 stores a table in which IDs are associated with digital camera functions in advance. Therefore, the adapter 105 determines whether the digital camera 100 is a camera having a function of generating a display image based on the received ID (step S405).

  Of course, determining the function of the digital camera 100 is not limited to the ID. For example, the adapter 100 may transmit a command for inquiring about the function to the digital camera 100.

  If it can be generated, a display image is generated (step S406), and the generated image is set as image data for transmission to an external device for display. If it cannot be generated, a warning image held in advance in the ROM 302 of the adapter 105 is set as image data to be transmitted to the external device and displayed (step S407).

  The adapter 105 creates an HTML document in the HTML document creation unit 307 using the image data to be sent (step S408), and sends the created HTML document to the external device (step S409). The external device displays the received image (step S410).

  For example, when “IMG — 0001.RAW” is selected in FIG. 6, if it is determined that an image for display can be generated, the browser 700 of the external device displays the image 700 of FIG. If it is determined that a display image cannot be generated, the image 600 in FIG. 9 is displayed.

  As described above, in this embodiment, the adapter 105 refers to the function of the digital camera 100 and generates and displays a display image when a display image can be generated, and displays a warning image when the image cannot be generated. I tried to make it. As a result, the user can view the image data on the browser. Further, it can be recognized that image data can be acquired even when it cannot be displayed on the browser.

<Other embodiments>
In the above embodiment, an example in which the digital camera 100 and the adapter 105 are separate devices has been described. By using the digital camera 100 and the adapter 105 as separate devices, the cost of the digital camera itself can be reduced, and exclusive control between the imaging unit and the communication unit is not required, and the system does not hinder shooting. However, the digital camera 100 having the function of the adapter 105 may be integrated.

  The case where the digital camera has an HTTP server function will be described below.

  By connecting the network communication I / F 304, the HTTP server 305, and the HTML document creation unit 307 of FIG. 3 to the system bus 210 of FIG. 2 and integrating them, a digital camera having the HTTP server 305 is obtained.

  The HTTP server 305 performs communication according to the HTTP protocol with a browser of an external device, and exchanges HTML documents.

  In communication between the browser function of the external device and the HTTP server 305, the HTML document creation unit 307 generates a signal exchanged between the browser of the external device and the HTTP server 305 as an HTML document. Examples of the signal include digital image data captured by the imaging unit 204 of the digital camera 100, a reduced image of the digital image data, setting data of the digital camera 100, control data of the digital camera, and the like.

  The flow of HTTP server processing when the digital camera has an HTTP server function is the same as the flow of HTTP server processing described above, and the processing of the adapter 105 is performed inside the digital camera 100.

  Thus, by integrating the digital camera 100 and the adapter 105, the user does not need to carry the adapter 105 separately from the digital camera 100.

  The object of the present invention is achieved by executing the following processing. That is, a storage medium that records a program code of software that realizes the functions of the above-described embodiments is supplied to a system or apparatus, and a computer (or CPU, MPU, etc.) of the system or apparatus is stored in the storage medium.
