Description

  The present invention relates to a technique for controlling display of an information processing apparatus by connecting an image processing apparatus such as a digital camera to an information processing apparatus such as a computer and operating the image processing apparatus.

  In general, image data captured by an imaging apparatus such as a digital camera is stored as an image file in a storage medium such as an SD card attached to the imaging apparatus. The stored image data can be taken into a personal computer or the like (hereinafter “PC”). In order to perform capture, the user connects the imaging device to the PC using a cable or the like. Then, an image file can be transferred to the imaging apparatus by starting an application on the computer side and operating the PC.

  At present, there is also known a technique for performing processing related to communication based on an operation of an imaging apparatus by performing communication between the imaging apparatus and a PC by PTP (Picture Transfer Protocol) (for example, Patent Document 1).

  By using such a technique, for example, when the image data is displayed on the display unit of the imaging device, the same image data is displayed on the display unit of the PC, so that the display on the imaging device side and the PC side can be displayed. It is also possible to synchronize.

  Here, as a function of the imaging device, posture information of the imaging device at the time of shooting can be added to an image file obtained by shooting. For example, it is possible to add information as to whether or not the image is taken with the image pickup apparatus held in the vertical position (the long side of the image pickup apparatus is in the vertical direction) (see, for example, Patent Document 2). When the captured image data is later displayed in the normal position (the long side of the imaging device is in the horizontal direction), the imaging device rotates and displays the image data captured in the vertical position based on the posture information. . By this processing, the vertical relationship of the subject at the time of shooting is correctly displayed.

In addition, in a system for displaying an image captured by an imaging device on a PC, a technique for reflecting posture information on the imaging device side on the display on the PC side is also known (for example, see Patent Document 3).

  The mode switch 60 can switch the operation mode of the system control unit 50 to any one of a still image recording mode, a moving image recording mode, a reproduction mode, and the like. The first shutter switch 62 is turned on while the shutter button 61 provided in the imaging apparatus 100 is being operated (half-pressed) to generate the first shutter switch signal SW1. The system control unit 50 starts operations such as AF (auto focus) processing, AE (auto exposure) processing, AWB (auto white balance) processing, and EF (flash pre-emission) processing in response to the first shutter switch signal SW1.

  The second shutter switch 64 is turned on when the operation of the shutter button 61 is completed (fully pressed) and generates a second shutter switch signal SW2.

  Reference numeral 106 denotes an attitude detection unit that detects the attitude of the image sensor 14. The posture includes, for example, “horizontal position” as the first direction and “vertical position” as the second direction. In this embodiment, when the angle formed by the long side of the image sensor 14 with the horizontal direction is smaller than the angle formed by the short side with the horizontal direction, the horizontal position is set. A case where the angle is larger than the angle formed with the direction is defined as a vertical position. In general, the orientation of the image sensor 14 and the orientation of the imaging device 100 often correspond to each other. In this case, the vertical position and the horizontal position also correspond to the orientation of the imaging device 100 such as the vertical orientation and the horizontal orientation.

  The posture detection unit 106 includes a sensor that detects gravity, and detects the posture of the subject device by sensing in which direction the subject is gravity. For example, if gravity is applied in the long side direction of the imaging apparatus 100, the posture detection unit 106 determines that it is in the vertical position, and determines that it is in the horizontal position if gravity is applied in the short side direction.

  By performing posture detection by the posture detection unit 106 during shooting, the imaging apparatus 100 can detect whether shooting has been performed in the horizontal position or in the vertical position.

  Reference numeral 200 denotes a recording medium such as a memory card or a hard disk.

<Overall Operation of Imaging Device>
First, an operation when the imaging apparatus 100 is not connected to a personal computer (hereinafter “PC”) will be described. FIG. 3 is a flowchart for explaining the operation of the imaging apparatus 100 according to this embodiment. This flow is realized by the system control unit 50 controlling each unit in accordance with a signal input from each unit or a program stored in the nonvolatile memory 56 or the like.

  First, this flow starts when the user operates the power switch 72 to turn on the power.

  In step S301, the system control unit 50 initializes flags, control variables, and the like.

  In step S302, the system control unit 50 performs flag setting S302 related to camera posture detection. Hereinafter, the posture mode flag setting in step S302 will be described.

  FIG. 5 is a flowchart showing processing relating to setting of the posture mode flag of the imaging apparatus 100 in step S302 of FIG. The posture mode flag in the present embodiment is a flag for switching whether the posture detection by the posture detection unit 106 is turned on or off.

  In step S501, the system control unit 50 determines whether the setting of the attitude mode switch included in the operation unit 70 is ON or OFF. If it is determined that the posture mode switch is set to ON, the process proceeds to step S502, and the posture mode flag is validated. If it is determined that the posture mode switch is set to OFF, the process proceeds to step S503, and the posture mode flag is canceled.

  The system control unit 50 stores information on whether or not the posture mode flag is valid in the system memory 52.

  The above is the process in step S302. Hereinafter, step S303 and subsequent steps in FIG. 3 will be described.

  In step S303, the system control unit 50 determines whether the mode switch 60 is set to the still image recording mode. If it is the still image recording mode, the process proceeds to step S304, and the still image recording mode is performed. If it is not the still image recording mode, the process proceeds to step S305. In step S305, the system control unit 50 performs a playback mode process.

  Details of the processing in steps S304 and S305 will be described later. After performing these processes, the system control unit 50 advances the process to step S306. In step S308, the system control unit 50 determines the set position of the power switch 72. If the power switch 72 is set to power on, the process returns to step S303. On the other hand, if the power switch 72 is set to power off, the process proceeds to step S307.

  In step S307, the system control unit 50 performs end processing. The termination process includes, for example, the following process. That is, the display of the image display unit 28 is changed to an end state, the lens barrier 102 is closed to protect the imaging unit, parameters, setting values, and setting modes including flags and control variables are recorded in the nonvolatile memory 56, Shut off the power to parts that do not require power supply. When the termination process of step S307 is completed, this process is terminated, and the power is turned off.

<Still image recording mode processing>
Hereinafter, the processing in the still image recording mode in step S304 in FIG. 3 will be described. FIG. 4 is a flowchart illustrating processing of the imaging apparatus 100 in the still image recording mode. Note that the still image recording mode process shown in FIG. 4 is terminated by an interrupt process or the like when the mode switch 60 is switched to another mode or when the power switch 72 is set to OFF. And

First, when starting the still image recording mode, the system control unit 50 determines the shooting mode in step S401. To confirm the shooting mode,
(1) Acquire the shooting mode at the end of the previous still image recording mode from the nonvolatile memory 56 and store it in the system memory 52, or
(2) When the operation unit 70 is operated by the user to give an instruction to set the shooting mode, the instructed shooting mode is stored in the system memory 52. Here, the shooting mode is a mode realized by combining a shutter speed, an aperture value, a flash emission state, sensitivity setting, and the like suitable for a shooting scene.

  In step S402, the system control unit 50 displays the image data obtained by the imaging unit 22 on the image display unit 28 (through display).

  In step S <b> 403, the system control unit 50 determines whether the remaining capacity of the power supply unit 30 configured by a battery or the like using the power supply control unit 80, the presence / absence of the recording medium 200, and the remaining capacity are problematic in the operation of the imaging apparatus 100. Judge whether or not. If there is a problem, the process proceeds to step S407, a predetermined warning display is performed with image data or sound using the image display unit 28, and the process returns to step S401.

  If there is no problem in the state of the power supply unit 30 and the recording medium 200, the system control unit 50 determines whether or not the first shutter switch signal SW1 is ON in step S404. If the first shutter switch signal SW1 is OFF, the process returns to step S404. On the other hand, if the first shutter switch signal SW1 is ON, the process proceeds to step S405.

  In step S405, the system control unit 50 determines the attitude mode flag. If the posture mode flag is ON, the process proceeds to step S406. If it is OFF, the process proceeds to step S408.

  In step S406, the system control unit 50 performs posture detection processing, and advances the processing to step S408. The posture detection process will be described later.

  In step S408, the system control unit 50 performs a distance measurement process to focus the lens 103 on the subject, and performs a photometry process to determine an aperture value and a shutter time (shutter speed). In the photometric process, a flash is set if necessary.

  Next, in steps S409 and S410, ON / OFF states of the first shutter switch signal SW1 and the second shutter switch signal SW2 are determined. If the second shutter switch signal SW2 is turned on while the first shutter switch signal SW1 is turned on, the process proceeds from step S409 to step S411. When the first shutter switch signal SW1 is turned off (when the second shutter switch signal SW2 is not turned on and the first shutter switch signal SW1 is also released), the process returns from step S410 to step S407. Further, while the first shutter switch signal SW1 is ON and the second shutter switch signal SW2 is OFF, the processes of steps S409 and S410 are repeated.

  In step S411, the system control unit 50 performs fixed color display on the image display unit 28. The fixed color display means that alternative image data is displayed while the sensor is performing the imaging process. Generally, black image data stored in advance is used.

  In step S412, the system control unit 50 executes shooting processing including exposure processing and development processing. In the exposure process, the image data obtained through the image pickup unit 22 and the A / D converter 23 is sent from the image processing unit 24 and the memory control unit 15 or directly from the A / D converter 23 to the memory control unit. 15 to the memory 32. In the development process, the system control unit 50 uses the memory control unit 15 and, if necessary, the image processing unit 24 to read the image data written in the memory 32 and perform various processes. At the start of this photographing process, the system control unit 50 acquires current date / time information from the internal timer and stores it in the system memory 52. This date / time information is information on the shooting date / time added to the image file.

  Next, in step S413, the system control unit 50 performs a REC review display of the image data obtained by the photographing process on the image display unit 28. The REC review is a process for displaying image data on the image display unit 28 for a predetermined time (review time) after photographing a subject and before recording on a recording medium in order to confirm the photographed image data. .

  After the REC review display, in step S414, the system control unit 50 executes a recording process for writing the image data obtained by the photographing process into the recording medium 200 as an image file. Details of the recording process will be described later.

  When the recording process in step S414 ends, in step S415, the system control unit 5 determines the ON / OFF state of the second shutter switch signal SW2. If the second shutter switch signal SW2 is ON, the determination in step S415 is repeated, and the process waits for the second shutter switch signal SW2 to be OFF. During this time, the display of the REC review is continued. That is, when the recording process in step S414 is completed, the REC review display on the image display unit 28 is continued until the second shutter switch signal SW2 is released. With this configuration, the user can carefully check the captured image data using the REC review by continuing to fully press the shutter button 61.

  After the user has taken a picture with the shutter button 61 fully pressed, when the user releases the shutter button 61 to release the fully pressed state, the system control unit 50 advances the process to step S416.

  In step S416, the system control unit 50 determines whether a predetermined review time has elapsed. If the review time has elapsed, the system control unit 50 advances the process to step S417.

  In step S417, the system control unit 50 returns the display state of the image display unit 28 from the REC review display to the through display state. With this process, after the captured image data is confirmed by the REC review display, the display state of the image display unit 28 is automatically switched to a through display state in which the image data from the imaging unit 22 is sequentially displayed for the next shooting. become.

  In step S418, the system control unit 50 determines whether the first shutter switch signal SW1 is ON / OFF. If the first shutter switch signal SW1 is ON, the process proceeds to step S409, and if it is OFF, the process proceeds to step S407. return. That is, when the half-pressed state of the shutter button 61 is continued (the first shutter switch signal SW1 is ON), the system control unit 50 prepares for the next shooting (step S409). On the other hand, if the shutter button 61 has been released (the first shutter switch signal SW1 is OFF), the system control unit 50 ends the series of shooting operations and returns to the shooting standby state (step S407).

<About posture detection processing>
Next, posture detection processing in the still image recording mode will be described. This process corresponds to step S406 in FIG. FIG. 6 shows a processing flow of the imaging apparatus 100 in the posture detection process.

  First, in step S <b> 601, the system control unit 50 detects the posture of the imaging apparatus 100 (specifically, the posture of the image sensor 14) by the posture detection unit 106.

  In step S602, the system control unit 50 determines whether the result of the camera posture detection process in step S1801 is a horizontal position or a vertical position. If it is the vertical position, the process proceeds to step S603, and the posture flag is set to “V” indicating the vertical position. If it is the horizontal position, the process proceeds to step S604, and the posture flag is set to “H” indicating the horizontal position. The values of these flags are stored in the system memory 52 or the nonvolatile memory 56.

<Recording process>
Next, recording processing in the still image recording mode will be described. This process corresponds to the process in step S414 in FIG. FIG. 7 is a flowchart showing processing of the imaging apparatus 100 in the recording processing of the present embodiment.

  First, in step S701, the system control unit 50 generates a file name of image data to be recorded, that is, image data obtained by the photographing process in step S412, according to a predetermined rule.

  In step S <b> 702, the system control unit 50 acquires date information stored in the system memory 52.

  In step S703, the system control unit 50 acquires the data size of the image data to be recorded.

  In step S <b> 704, the system control unit 50 accesses the recording medium 200, and determines whether or not the recording medium 200 has a directory in which an image file generated from image data to be recorded exists. If the directory does not exist, the process proceeds to step S705. If the directory exists, the process of step S705 is skipped, and the process proceeds to step S706.

  In step S705, the system control unit 50 generates a directory for storing the image file, and the process proceeds to step S706.

  In step S706, the system control unit 50 generates a file header including shooting date and time, shooting time conditions, and the like for the image data to be stored. The header generation process will be described later.

  In step S707, the system control unit 50 generates a directory entry from the file name acquired in step S701 and the date / time information acquired in step S703. Also, the image file is recorded on the recording medium 200, and the recording process is terminated.

<About header generation processing>
Here, the header generation processing in the still image recording mode will be described. This process corresponds to the process in step S706 of FIG. FIG. 8 is a flowchart showing the processing of the imaging apparatus 100 in the header generation processing of the present embodiment.

  First, in step S801, the system control unit 50 refers to the system memory 52 and determines whether or not the attitude mode flag described above with reference to FIG. If it is determined that the posture mode flag is on, the process proceeds to step S802. If it is determined that the attitude mode flag is not on, that is, it is off, the process proceeds to step S803.

  In step S802, the system control unit 50 reads the value of the attitude flag stored in the system memory 52 in the attitude detection process in step S406. When the read posture flag value is the horizontal position, the fact that the rotation attribute is the horizontal direction is written in the header. If the value of the read attitude flag is vertical, the fact that the rotation attribute is the vertical direction is written in the header. When the writing of the rotation attribute is completed, the process proceeds to step S803.

  In step S803, the system control unit 50 creates header information using setting values such as date and time information, and completes this process.

  Here, FIG. 9 shows an example of the structure of still image file data recorded on the recording medium 200 in the recording process. Various attribute information is written in the header information.

The image file 901 has a marker (SOI) 902 indicating the start of the image file at the head, followed by an application marker (APP1) 903 corresponding to the header portion. In the application marker (APP1) 903,
・ Size (APP1 Length) 904,
Application marker identification code (APP1 Identifier Code) 905,
Image data creation date / time (Date Time) 906,
Date and time (Date Time Original) 907 when the image data was generated
-Image data rotation information (Orientation) 908,
・ Other shooting information 909,
A thumbnail image (Thumbnail Data) 910.

  Of these header information, the rotation attribute described in step S802 is written in the field of the rotation information 908. When the rotation attribute is written as the attribute information, attribute information indicating the direction in which the image data is displayed is added.

  The image data recorded in the image file 901 includes a quantization table (DQT) 911, a Huffman table (DHT) 912, a frame start marker (SOF) 913, a scan start marker (SOS) 914, and compressed data 915. The Then, it is terminated with a marker (EOI) 916 indicating the end of the image file data.

  Up to this point, the processing in the still image recording mode in step S304 of FIG. 3 has been described. Next, processing in the playback mode will be described.

<About playback mode processing>
Hereinafter, processing in the playback mode will be described. This process corresponds to the process in step S306 of FIG. FIG. 10 is a flowchart for describing processing of the imaging apparatus 100 in the playback mode.

  First, in step S1001, the system control unit 50 accesses the recording medium 200 and acquires information on the latest image file. The latest image file in the present embodiment refers to the most recently stored image file among the image files stored in the recording medium 200.

  In step S1002, the system control unit 50 reads the latest image data from the recording medium 200 based on the latest image file information acquired in step S1001.

  In step S1003, the system control unit 50 displays the read image data. The image display process in this step will be described later.

  In step S1004, the system control unit 50 causes the imaging apparatus 100 to shift to an input waiting state such as a user operation.

<Image display processing>
Here, the image display processing in the reproduction mode will be described. This process corresponds to step S1003 in FIG. FIG. 11 is a flowchart showing processing of the imaging apparatus 100 in the image display processing.

  First, in step S1101, the system control unit 50 performs posture detection processing. This is the same as the processing in step S406 in FIG.

  In step S1102, the system control unit 50 acquires the rotation attribute 908 from the file header.

  In step S1003, the presence / absence of a rotation attribute is determined. If the rotation attribute is added in the determination in step S1103, that is, if a value indicating the horizontal direction or the vertical direction is written, the process proceeds to step S1104.

  In step S1104, the system control unit 50 determines the type of rotation attribute. If it is determined that the rotation attribute is horizontal, the process advances to step S1105. If it is determined that the direction is vertical, the process advances to step S1107.

  First, the case where the rotation attribute is in the horizontal direction will be described. In step S1105, the system control unit 50 determines whether the orientation of the imaging device detected in step S1101 is a vertical position or a horizontal position. If it is in the horizontal position, the process proceeds to step S1106, and the process of displaying the image data in the horizontal position is performed. If it is the vertical position, the process advances to step S1108 to perform a process of rotating and displaying the image data.

  If the rotation attribute is the vertical direction, in step S1107, the system control unit 50 determines whether the posture flag of the imaging device detected in step S1101 is “H” or “V”. If it is “H”, the process proceeds to step S1108, where the image data is rotated and displayed in the vertical position. If “V”, the process proceeds to step S1106, and a process of displaying image data in the horizontal position is performed.

  An example of the display of the image data is shown in FIGS. First, the case where the rotation attribute added to the image data is in the horizontal direction will be described with reference to FIG. FIG. 12A shows image data obtained by imaging.

  FIG. 12B shows a display when the orientation of the imaging apparatus 100 is the horizontal position. In this case, the system control unit 50 displays the image data expanded in the address direction of the memory 32, and the image data is displayed over the entire display area of the image display unit 28. This is a horizontal position display which is an example of a display form in the first orientation.

  FIG. 12C shows a display when the posture of the imaging apparatus 100 is the vertical position. In this case, the system control unit 50 develops the image data in the direction perpendicular to the address direction of the memory 32. Accordingly, the image data is displayed after being rotated by 90 degrees. Note that when such a rotation display is performed, a blank area is generated, so that fixed color data such as black is displayed (1201, 1202). This is the vertical position display which is an example of the display form in the second orientation.

  Next, the case where the rotation attribute is in the vertical direction will be described with reference to FIG. FIG. 13A shows image data obtained by imaging.

  FIG. 13B shows a display when the orientation of the imaging apparatus 100 is the horizontal position. In this case, the system control unit 50 develops the image data in the direction perpendicular to the address direction of the memory 32. Therefore, the image data is displayed in the vertical position.

  FIG. 13C shows a display when the posture of the imaging apparatus 100 is the vertical position. In this case, the system control unit 50 expands the image data in the address direction of the memory 32 and displays the horizontal position.

  If it is determined in step S1103 that the rotation attribute does not exist, that is, nothing is written in the rotation information field 908, the system control unit 50 advances the process to step S1106.

  Here, a case where no rotation attribute exists will be described. Some imaging devices do not add a rotation attribute during shooting. In some cases, a storage medium storing an image file to which no rotation attribute is added is attached to the imaging apparatus 100. In such a case, an image file having no rotation attribute exists in the additionally stored image file. In such a case, the system control unit 50 cannot determine the display direction of the image data based on the rotation attribute. Therefore, the system control unit 50 according to the present embodiment advances the processing to step S1106 in the case of image data having no rotation attribute, and uniformly displays the horizontal position.

  As described above, the system control unit 50 according to the present embodiment performs display according to the rotation attribute of the image file and the posture of the imaging apparatus 100. This flow is performed not only when the image data is displayed for the first time, but also when the posture detection unit 106 detects a change in the posture of the imaging apparatus 100 during the display of the image data. That is, when the user changes the orientation of the imaging apparatus 100, the vertical position display and the horizontal position display of the image data being displayed are switched.

<About communication system configuration>
So far, the process of capturing and displaying image data with the imaging apparatus 100 has been described. Next, a case where the imaging device 100 and the PC are connected will be described.

<Transmission of image data in communication mode>
Transmission of image data in the communication mode will be described. FIG. 16 shows a flowchart of processing performed by the imaging apparatus 100 and the PC 1501. The left side from the dotted line in the flowchart shows the process of the imaging apparatus 100, and the right side from the dotted line shows the process of the PC 1501.

  First, in step S1601, the CPU 1406 determines based on the state of the image input I / F 1405 whether or not a connection with the imaging device has been detected. If it is determined that a connection has been detected, the process advances to step S1602. If it is determined that it has not been detected, the process is repeated.

  In step S1602, the PC 1501 requests the image capturing apparatus 100 for a list of image data recorded on the recording medium 200 of the image capturing apparatus 100.

  In step S1603, the system control unit 50 creates and transmits a list in response to a request from the PC 1501. In this list, object handles such as image data recorded on the recording medium 200 are described.

  In step S <b> 1604, the CPU 1406 receives a list from the imaging apparatus 100.

  In step S <b> 1605, the CPU 1406 transmits an acquisition request to the imaging apparatus 100 by specifying image data according to the list received from the imaging apparatus 100. Note that a thumbnail of the image data may be acquired prior to this processing. In addition, a request for collectively acquiring image data or thumbnails indicated by the list may be made.

  In step S1606, the system control unit 50 transmits the image data requested from the PC 1501.

  In step S1607, the CPU 1406 receives the image data transmitted from the imaging apparatus 100, records it in the HDD 1409, and ends the process. These processes are repeated for the desired image data.

  In step S1608, the CPU 1406 determines whether all image data shown in the list has been received from the imaging apparatus 100. If it is determined that it has been received, the process ends. If it is determined that it has not been received, the process returns to step S1605, and an acquisition request for image data that has not been received is transmitted.

  The processing for transmitting image data from the imaging apparatus 100 to the PC 1501 has been described above. As a result, the imaging apparatus 100 and the PC 1501 are in a state of holding the same image data. Next, image data reproduction processing in a state where the imaging apparatus 100 and the PC 1501 are connected will be described.

<Operation in synchronized playback mode>
When the connection between the imaging apparatus 100 and the PC 1501 is established, both the imaging apparatus 100 and the PC 1501 shift to the synchronous playback mode.

  First, the operation of the imaging apparatus 100 in the synchronized playback mode will be described. FIG. 17 is a flowchart illustrating processing of the imaging apparatus 100 in the synchronous playback mode.

  First, in step S <b> 1701, the system control unit 50 displays image data on the image display unit 28. The image data displayed here is predetermined image data, for example, may be image data captured most recently, or may be image data that has already been displayed immediately before connection to the imaging apparatus 100. Whether the image data is displayed in the vertical position or the horizontal position is determined according to the flowchart of FIG.

  First, as a first transmission process, in step S1702, the system control unit 50 transmits information specifying the image data displayed in step S1701 to the PC 1501. The information to be transmitted here may be identification information for the PC 1501 to specify the image data being displayed on the imaging apparatus 100, such as a file name or an object handle of the image data being displayed. Through the processing in this step, the PC 1501 can synchronize the display with the imaging apparatus 100.

  In step S1703, the system control unit 50 determines whether or not a rotation attribute is added to the image data being displayed. If it has been added, the process advances to step S1704. If not, the process advances to step S1706.

  First, a case where it is determined that a rotation attribute is added will be described. In step S1705, the system control unit 50 refers to the rotation attribute of the image data being displayed, and determines whether the rotation information is horizontal or vertical. If it is in the horizontal direction, the process advances to step S1705. If so, the process advances to step S1707. Based on the determination result in this step, a signal to be transmitted in the second transmission process in step S1705 or step S1707 is determined.

  In step S1705, the system control unit 50 transmits a horizontal position display request to the PC 1501. This horizontal position display request includes an instruction for displaying the image data displayed on the display unit 1401 of the PC 1501 in the horizontal position. By this processing, display reflecting the rotation attribute can also be performed on the PC 1501 side.

  In step S1706, that is, the system control unit 50 transmits an instruction to rotate the image data displayed on the display unit 1401 of the PC 1501 according to its own posture.

  In step S1707, the system control unit 50 transmits a vertical position display request to the PC 1501. This vertical position display request is a signal including an instruction for displaying the image data displayed on the display unit 1401 of the PC 1501 in the vertical position. By this processing, display reflecting the rotation attribute can also be performed on the PC 1501 side.

  In this embodiment, in step S1704, the imaging apparatus 100 determines the rotation attribute and transmits a request for controlling the display of the PC 1501, but the PC 1501 refers to the rotation attribute added to the image data and displays the same display as the imaging apparatus 100. Control may be performed.

  Next, a case where it is determined in step S1703 that no rotation attribute is added will be described. In step S1706, the attitude of the imaging apparatus 100 is detected, and it is determined whether the attitude flag is “H” or “V”. The posture detection process is executed according to the flowchart of FIG. If it is determined that the posture flag is “H”, the process advances to step S1705 to transmit a lateral position display request. If it is determined that it is “V”, the process advances to step S1707 to transmit a vertical position display request. That is, in the processes of steps S1706, S1705, and S1707, the system control unit 50 transmits an instruction for controlling the display of the PC 1501 according to the attitude of the imaging apparatus 100.

  The PC 1501 in this embodiment can add a rotation attribute to image data to which no rotation attribute is added. The instruction to add the rotation attribute can be performed by the user operating the imaging apparatus 100.

  In step S1708, the system control unit 50 determines whether or not an instruction to add a rotation attribute has been given by a user operation. If it is determined that an instruction has been given, the process advances to step S1709. If it is determined that no instruction has been given, the process advances to step S1710.

  As a third transmission process, in step S1709, the system control unit 50 transmits a rotation information addition request to the PC 1501. The rotation information addition request is a signal that requests the PC 1501 to add a rotation attribute to the image data being displayed on the display unit 1401 of the PC 1501.

  In step S1710, the system control unit 50 determines whether switching of image data to be displayed is instructed by a user operation. If it is determined that the image has been switched, the process returns to step S1701, the image data after the switching is displayed, and information specifying the image data is transmitted to the PC 1501. If it is determined that it has not been switched, the process returns to step S1703.

  If the user moves the imaging device 100 during the synchronous playback mode and the orientation of the imaging device 100 changes, the process starts from step S1703. Then, based on the rotation attribute or the orientation of the imaging device 100, the horizontal position display request or the old vertical position display is retransmitted.

  The above is the operation of the imaging apparatus 100 in the synchronous playback mode.

  Next, the operation of the PC 1501 in the synchronized playback mode will be described. FIG. 18 is a flowchart showing the processing of the PC 1501 in the synchronous playback mode.

  First, in step S1801, the CPU 1406 determines whether information specifying image data displayed on the imaging apparatus 100 has been received from the imaging apparatus 100 as the first reception process. Information for specifying image data is transmitted from the imaging apparatus 100 in step S1702 of FIG. If it is determined that it has been received, the process proceeds to step S1802. If it is determined that it has not been received, the process is repeated.

  In step S1802, the CPU 1406 identifies image data from the information received in step S1801, and reads it from the HDD 1409. Then, it is displayed on the display unit 1401. By this processing, the image data displayed on the imaging apparatus 100 and the image data displayed on the PC 1501 become the same, and the synchronous display of the image data is realized.

  In step S1803, the CPU 1406 determines whether a display request for either a vertical position display request or a horizontal position display request has been received from the imaging apparatus 100 as the second reception process. These display requests are transmitted from the imaging apparatus 100 in steps S1705 and S1707 in FIG. If it is determined that a horizontal position display request has been received, the process advances to step S1804. If it is determined that a vertical position display request has been received, the process advances to step S1805. If it is determined that no display request has been received, the process ends.

  In step S1804, if the image data being displayed is displayed in the horizontal position, the CPU 1406 rotates the image data and displays it in the vertical position. If it is already displayed in the vertical position, it continues to be displayed.

  In step S1805, if the image data being displayed is displayed in the vertical position, the CPU 1406 rotates the image data and displays it in the horizontal position. If it is already displayed in the vertical position, it continues to be displayed.

  FIGS. 19A and 19B show examples of display screens of the imaging apparatus 100 and the PC 1501 in the synchronous playback mode.

  FIG. 19A shows a screen for browsing image data to which no rotation attribute is added with the imaging apparatus 100 in the vertical position. In this case, there is no rotation attribute (step S1703 / NO in FIG. 17), and the attitude flag is “V” (step S1706 / V in FIG. 17). As a result, a vertical position display request is transmitted to the PC 1501. As a result, the screen shown in FIG. 19B is displayed on the PC 1501. That is, when the imaging apparatus 100 is in the vertical orientation (vertical position), an instruction to display image data in the vertical position is transmitted from the imaging apparatus 100 to the PC 1501. Therefore, the display unit 1401 on the PC 1501 side rotates the image data and displays the image data in the vertical position. Through the above processing, the CPU 1406 can rotate and display the image data according to the orientation of the imaging apparatus 100, and the orientation of the image data displayed on the imaging apparatus 100 can be aligned with the orientation of the image data displayed on the PC 1501. .

  Returning to FIG. 18, the processing from step S1806 will be described. The PC 1501 in this embodiment can add a rotation attribute to image data to which no rotation attribute is added. In the processing after step S1806, processing for adding a rotation attribute will be described.

  In step S1806, the CPU 1406 determines whether a rotation attribute is added to the image data. If it is determined that the rotation attribute is added, the process ends. If it is determined that no rotation attribute is added, the process advances to step S1807.

  In step S1807, the CPU 1406 determines whether a rotation attribute addition request has been received from the imaging apparatus 100 as the third reception process. The rotation attribute addition request is transmitted from the imaging apparatus 100 in step S1709 in FIG. If it is determined that a rotation attribute addition request has been received, the process advances to step S1808. If it is determined that it has not been received, the process ends.

  In step S1808, the CPU 1406 adds a rotation attribute to the image data being displayed. When the image data being displayed is displayed in the horizontal position, a horizontal rotation attribute is added. When the image data is displayed in the vertical position, a vertical rotation attribute is added.

  In step S1809, the CPU 1406 duplicates the image data to which the rotation attribute is added and transmits the image data to the imaging apparatus 100. The system control unit 50 that has received the transmitted image data overwrites the corresponding image data in the recording medium 200. With this processing, it is possible to add a rotation attribute to not only the image data stored in the HDD 1409 of the PC 1501 but also the image data stored in the recording medium 200 of the imaging apparatus 100. Note that an instruction may be transmitted from the PC 1501 to the imaging apparatus 100 to add a rotation attribute without transmitting image data.

  If information specifying image data is received during the synchronous playback mode, the process starts from step S1801. For example, when the display switching of the image data is performed as in step S1710 of FIG. 17, information for newly specifying the image data is received. In that case, the system control unit 50 executes the process from step S1801 again.

  If a vertical position display request or a horizontal position display request is received during the synchronous playback mode, the process starts from step S1803. For example, if the orientation of the image capturing apparatus 100 changes due to the user moving the image capturing apparatus 100 during this flow, a new vertical position display request or horizontal position display request is received. In that case, the imaging apparatus 100 executes the processing from step S1803 again.

  The above is the operation in the synchronized playback mode. As described above, the system control unit 50 in this embodiment controls the display on the PC 1501 side by transmitting a vertical position display request or a horizontal position display request according to the attitude of the imaging apparatus 100.

  In addition, the system control unit 50 according to the present embodiment determines whether to send a vertical position display request or a horizontal position display request to the PC 1501 depending on whether or not a rotation attribute is added to the image data. did. As a result, on the PC 1501 side, an image to which a rotation attribute is added is displayed in an orientation according to the rotation attribute, and an image to which no rotation attribute is added is an image according to the orientation of the imaging apparatus 100. Will be displayed.

  As a result, the vertical position and the horizontal position of the image data displayed on the PC 1501 side are appropriately displayed, so that the user can view the image data displayed on the PC 1501 comfortably.

<Second Embodiment>
In the first embodiment, the case has been described in which the imaging apparatus 100 and the PC 1501 display image data one by one on one screen. In the present embodiment, a case will be described in which the imaging apparatus 100 and the PC 1501 execute a so-called multi display in which a plurality of pieces of image data are displayed on one screen.

  Since this embodiment has many parts in common with the first embodiment, description of common parts will be omitted, and description will be made focusing on characteristic parts of this embodiment. Note that the first embodiment and the second embodiment can be appropriately combined.

  The imaging apparatus 100 according to the present embodiment can set a display mode. The display mode includes a normal display mode for displaying one image data on one screen and a multi display mode for displaying a list of a plurality of image data on one screen. The display mode is set by the user operating the operation unit 70 and selecting a desired mode. FIG. 20A shows an example of a display screen of the imaging apparatus 100 in the multi display mode. As shown in FIG. 20A, the image display unit 28 of the imaging apparatus 100 displays nine pieces of image data on one screen. Reference numeral 2001 denotes image data in a selected state, which is highlighted with a thick frame.

  Next, the case where the multi-display mode is set in the synchronous playback mode will be described with reference to FIGS. Here, it demonstrates centering on difference with 1st Embodiment.

  In step S <b> 1701, the system control unit 50 transmits information for specifying image data for all the image data that are displayed in a multi display. That is, in the example of FIG. 20A, information for specifying nine pieces of image data is transmitted. Information for specifying the image data in the selected state is also transmitted to the PC 1501.

  In step S1802, the CPU 1406 multi-displays the image data on the display unit 1401 based on the information received in step S1801. An example of a screen displayed on the PC 1501 is shown in FIG. Since the PC 1501 also receives information for specifying the image data in the selected state, the image data 2002 in the selected state is highlighted with a thick frame.

  As described above, even in the case of multi-display, the display on the imaging apparatus 100 side and the PC 1501 side can be reproduced in synchronization.

  Next, the relationship between multi-display and vertical / horizontal position display will be described. The image data displayed on the image display unit 28 in the multi-display mode in this embodiment is always displayed in the horizontal position. This does not depend on the rotation attribute or the orientation of the imaging device 100. As an example, FIG. 21A shows a display example when the imaging apparatus 100 is oriented vertically. For example, even if the rotation attribute “horizontal direction” is added to the image data 2103, the image is displayed in the horizontal position in the multi-display mode in the present embodiment. The reason is as follows. That is, in the multi-display mode, a plurality of image data is displayed on one screen, so the display size per image data is reduced. Therefore, although the listability is improved as compared with the normal display mode, the visibility of individual image data is deteriorated. When the vertical position display is performed in such a multi-display mode, the display size of the image data is further reduced, and the image data may be difficult to see. In the case of a portable device such as an imaging device, the user can view the image data at the correct position by rotating the imaging device by 90 degrees. Therefore, in the multi-display mode according to the present embodiment, all image data is displayed in the horizontal position regardless of the rotation attribute and the orientation of the imaging device 100.

  Next, the relationship between the synchronized playback mode and the vertical / horizontal position display will be described. The processes in steps S1703 to S1709 in FIG. 17 are performed only for the image data in the selected state. For example, in the example of FIG. 21A, since the image data 2101 is in a selected state, the system control unit 50 executes steps S1703 to S1709 only for the image data 2101.

  For example, consider a case where no rotation attribute is added to the image data 2101. In this case, when the imaging apparatus 100 is turned vertically, the system control unit 50 transmits the vertical position display request to the PC 1501 in step S1707 as a result of executing the processes of steps S1703 and S1706. This vertical position display request includes information for specifying the image data in the selected state.

  The CPU 1406 identifies the image data in the selected state based on the received information and displays it in the vertical position. FIG. 21B shows an example of the display screen. When the imaging apparatus 100 is oriented vertically as shown in FIG. 21A, the image data 2102 of the display unit 1401 of the PC 1501 is displayed in a vertical position. Other image data remains in the horizontal position.

  As described above, the imaging apparatus 100 according to the present embodiment is configured to control the display of the PC 1501 in consideration of the state of the imaging apparatus 100 even on a multi-display screen. Thus, the user can view the image data more comfortably even on the multi-display screen.

  Further, in the multi-display mode in the present embodiment, the image display apparatus 100 always displays in the horizontal position, and the PC 1501 side displays the vertical position as necessary. Thereby, the visibility of individual image data displayed on the imaging device side can be maintained. On the other hand, since the PC 1501 generally has a larger display unit 1401 than the imaging device 100, the visibility can be maintained even when displayed vertically. Therefore, it is possible to display the image in the vertical position on the PC 1501 side, and the user can view the image data comfortably without operating the PC 1501 in particular.

  Note that the processing in steps S1703 to S1709 may be performed on all the image data that are displayed in multiple. However, from the viewpoint of appropriately displaying the image data focused on by the user, it is more preferable to execute the processes in steps S1703 to S1709 only on the image data in the selected state.
