Description

  The present invention relates to an imaging device, a remote control device, a control method, a program, and a storage medium.

  In recent years, an imaging apparatus such as a digital still camera and a digital video camera can record not only a captured image but also various additional information in association with the captured image. Such additional information includes, for example, photographer information, shooting location information, imaging device identification information, lens information, and shooting condition information, and may further include character information such as a photographer (user) comment. Such additional information is used as, for example, a search key for searching for a target image when performing an editing operation.

  A configuration using a general-purpose data processing device having a display means, an operation means, and a communication means has been proposed as a remote control device for operating these imaging devices remotely and setting shooting conditions and the like. Such a data processing apparatus is, for example, a personal computer or a smartphone equipped with a display and a pointing device such as a mouse, and is installed with an application program for remote operation. These data processing devices can remotely operate the imaging device via a wired or wireless communication medium, and can transfer additional information and the like to the imaging device.

  In Patent Document 1, in a system that can transfer additional information from the operating device to the recording device, the user uses the operating device to determine whether the additional information is recorded in association with the immediately preceding recording, the next recording, or the content being recorded. The configuration designated for the recording apparatus is described.

  FIG. 1 shows a configuration diagram of an embodiment of an imaging system comprising an imaging device and a remote control device according to the present invention, and FIG. 2 shows a schematic configuration block diagram thereof. In this embodiment, the PC 100 can control whether or not additional information (here, metadata) is to be recorded in the imaging apparatus 150 in conjunction with metadata registration / deletion operations.

  A PC (personal computer) 100 which is a remote control device can be connected to the imaging device 150 via the connection cable 140 and can control the imaging device 150. The connection cable 140 is, for example, a connection cable conforming to the IEEE 1394 standard or a USB (Universal Serial Bus) connection cable. Here, the connection cable 140 includes a data line for transmitting data bidirectionally, a strobe signal line for transferring a strobe signal, a power supply line, and the like. When the PC 100 and the imaging device 150 are connected by the connection cable 140, data transfer from the imaging device 150 to the PC 100 and control of the imaging device 150 by the PC 100 become possible. Of course, the PC 100 and the imaging apparatus 150 are equipped with a function that supports a communication protocol corresponding to IEEE 1394 or USB. The strobe signal line is a line through which a data transmission side transmits a strobe signal that is a signal for notifying the data reception side of data transmission. Data transfer is performed at both rising and falling edges of the strobe signal. The data receiving side receives the data transmitted from the data transmitting side through the data line and the strobe signal line. The power supply line is a line for supplying power from the PC 100 to the imaging device 150 as necessary.

  The configuration and basic operation of the PC 100 will be described with reference to FIG. As illustrated in FIG. 2, the PC 100 includes a CPU 102, a memory 104, a communication unit 106, a display unit 108, and an operation unit 110.

  A CPU (Central Processing Unit) 101 controls the operation of the PC 100 according to a computer program stored in the memory 104. In addition, the CPU 102 has a timer (not shown), and measures the elapsed time of processing executed by each unit.

  The memory 104 is used as a main memory of the CPU 102 and stores data from the imaging device 150 received from the communication unit 106. The memory 104 stores a plurality of icons for notifying the user of the state of the PC 100, a computer program for controlling the operation of the PC 100, and the like. The memory 104 also stores a menu screen to be displayed on the display unit 108. The computer program of the memory 104 includes a command communication unit that transmits / receives a control command, a confirmation signal, a status signal, and data to / from the imaging device 150, and a metadata generation unit that generates metadata to be added to a captured image. To function as.

  The communication unit 106 has a connection terminal to which the connection cable 140 is connected. The communication unit 106 receives image data, audio data, and auxiliary data transmitted from the imaging device 150 via the connection cable 140 and outputs them to the CPU 102. The CPU 102 stores the image data transmitted from the imaging device 150 in the memory 104 and displays it on the display unit 108, and outputs the sound of the audio data transmitted from the imaging device 150 from a speaker unit (not shown).

  The display unit 108 includes a display device such as a liquid crystal display. The display unit 108 can display the image data stored in the memory 104 and the image data received by the communication unit 106 under the control of the CPU 102. The display unit 108 also displays a menu screen that is a graphical user interface stored in the memory 104 under the control of the CPU 102. The menu screen includes a PC control screen for controlling the PC 100, a PC setting screen for changing settings of the PC 100, and a camera control screen for remotely controlling the imaging device 150. When these menu screens are displayed on the display unit 108, the CPU 102 superimposes and displays an icon in the shape of a mouse cursor arrow on the menu screen. The display unit 108 displays an image of the image data supplied from the communication unit 106 in a predetermined area of the camera control screen supplied from the CPU 102.

  The operation unit 110 is a user interface for operating the PC 100. The operation unit 110 includes a mouse 110a, a pointing device such as a tablet or a trackball, and a keyboard 110b as operation means for operating the PC 100. Using this pointing device, the user can operate the mouse cursor superimposed on the menu screen on the menu screen. For example, when the mouse cursor moves on the menu screen according to the position information of the pointing device on the menu screen and the pointing device is pressed, the CPU 152 executes processing according to the position where the mouse cursor exists.

  FIG. 3 shows an example of the camera control screen. A camera control screen 300 shown in FIG. 3 is configured on a window system that is standardly adopted by the OS (operating system) of the PC 100.

  The camera control screen 300 includes a view area 302 for displaying an image, a status area 304 for displaying the status of the control system as character information, a shutter button 306, and a parameter area 308 for displaying parameters of the imaging apparatus 150. The view area 302 is an area for displaying a live view video continuously received by the communication unit 106 from the imaging device 150 or a still image received by a shooting operation. The status area 304 is an area indicating a control state. As the control state, in addition to “capable of photographing” shown in FIG. 3, there are “preparing for photographing” and “during photographing processing”.

  The shutter button 306 can accept imaging processing instructions corresponding to two states, a half-pressed state and a fully-pressed state of the shutter button of the imaging device 150. When the mouse cursor 312 moves onto the shutter button 306, the PC 100 instructs the imaging device 150 to start processing corresponding to the half-pressed state (imaging preparation processing). When the user performs a click operation while the mouse cursor 312 is on the shutter button 306, the PC 100 instructs the imaging device 150 to start an operation of a process corresponding to the fully pressed state (a series of imaging processes).

  The parameter area 308 displays the shooting mode, shutter speed, aperture value, and the like. These values are included in auxiliary data received from the imaging device 150. The parameter area 308 may display auxiliary data other than this. When the value on the parameter area 308 is changed by the operation, the CPU 102 generates an auxiliary data setting command and transmits the auxiliary data setting command from the communication unit 106 to the imaging device 150. Thereby, the parameter of the imaging device 150 is changed.

  The metadata setting button 310 is a button for transitioning to a metadata registration screen recorded together with the photographed image. The metadata (attribute information) includes IPTC (International Press Telecommunications Council) information. The IPTC information contains information representing the contents of a photograph, and is defined as metadata that can be understood when the photograph data is exchanged between companies. The IPTC information includes IPTC contact information, IPTC image, IPTC content, and IPTC status. The IPTC contact information includes the creator, the title of the creator, address, city name, prefecture name, postal code, country name, telephone number, e-mail, and Web site information. The IPTC image includes information on a creation date, a genre, an IPTC scene, a shooting location, a municipality, a prefecture name, a country name, and an ISO country code. The IPTC content includes information of a headline, a description, a keyword, an IPTC subject code, and a description writer. The IPTC status includes information such as a title, a job ID, an instruction, a provider, an owner or a copyright holder, copyright information, and a rule regarding specifications.

  FIG. 4 shows an example of the metadata registration screen of the camera control screen 300. The parameter area 400 displays a headline, a description, a keyword, an IPTC subject code, a description writer, and the like. These values serve as auxiliary data to be registered later as metadata in the imaging apparatus 150. However, when the imaging device 150 and the PC 100 are connected, the PC 100 receives auxiliary data from the imaging device 150. When the camera control screen is opened at this stage, the CPU 102 displays the corresponding value of the auxiliary data received immediately before from the imaging device 150 in the parameter area 400. The parameter area 400 may display auxiliary data other than the items illustrated in FIG.

  The parameter display tab 402 is an operation member for switching information displayed in the parameter area 400 for each category. When the mouse cursor 312 is clicked in any of the parameter display tabs 402, information displayed in the parameter area 400 can be switched.

  The metadata registration button 404 is a button for instructing registration of the metadata input in the parameter area 400 to the imaging device 150. In response to the operation of the metadata registration button 404, the CPU 102 generates an auxiliary data setting command and transmits it to the imaging device 150 from the communication unit 106. Thereby, the imaging device 150 changes each parameter value of the auxiliary data.

  The metadata deletion button 406 is a button for instructing deletion of metadata registered in the imaging apparatus 150. In response to the operation of the metadata deletion button 406, the CPU 102 generates an auxiliary data setting command and transmits the auxiliary data setting command from the communication unit 106 to the imaging device 150. Thereby, the imaging device 150 deletes each parameter value of the auxiliary data.

  The shooting screen button 408 is a button for instructing transition to the shooting screen.

  The CPU 102 performs control so that each data transmitted from the imaging device 150 and received by the communication unit 106 is displayed in corresponding areas of the view area 302, the status area 304, and the parameter area 308.

The CPU 152 acquires information regarding the PC 100 from the PC 100 via the connection cable 140 and stores the information in the memory 154. In addition, the memory 154 stores a computer program for controlling the imaging device 150, predetermined image data and icons displayed on the display unit 158, and the like. By the computer program in the memory 154, the CPU 152 functions as a camera command detection unit that receives a camera command from the PC 100, and a recording unit that records a captured image and metadata on a recording medium. In addition, the CPU 152 functions as a writing unit that stores the metadata sent from the PC 100 in the memory 154 and a metadata recording setting unit that sets whether to add the metadata to the captured image for recording. Furthermore, the CPU 152 functions as a determination unit that determines whether the content of the metadata record is valid, and a transmission unit that sends a confirmation command to the PC 100.

  The basic operation of the shooting mode will be described. The imaging unit 162 images a subject and generates an image (image data) from the optical image of the subject. The image generated by the imaging unit 162 is supplied to the communication unit 156, the image processing unit 164, and the display unit 158. Audio data generated by a microphone unit (not shown) is also supplied to the recording unit 166 and the communication unit 156. In addition, the recording unit 166 records an image on which various image processing has been performed by the image processing unit 164 as an image file (still image file or moving image file) on a recording medium. Audio data generated by a microphone unit (not shown) is also recorded on the recording medium. For example, it is recorded as a sound of a moving image file and recorded as a voice memo in an independent sound file format.

  The basic operation of the playback mode will be described. The recording unit 166 reproduces image data (image file) and audio data selected by the user from the recording medium. The image data reproduced from the recording medium is supplied to the display unit 158 and the communication unit 156, and the audio data reproduced from the recording medium is supplied to the communication unit 156 and a speaker unit (not shown).

  A recording medium used in the recording unit 166 may be a built-in recording device 150 or a recording medium removable from the imaging device 150. In the case of a removable recording medium, a media cover for closing a slot for storing the recording medium and an open / close detection means for detecting opening / closing of the media cover are prepared.

  The communication unit 156 has a connection terminal to which the connection cable 140 is connected. In the shooting mode, the communication unit 156 transmits the image generated by the image processing unit 164, audio data generated by a microphone unit (not shown), and auxiliary data generated by the CPU 102 to the PC 100 via the connection cable 140. To do. In the reproduction mode, the communication unit 156 transmits image data and audio data reproduced from the recording medium by the recording unit 166 and auxiliary data generated by the CPU 102 to the PC 100 via the connection cable 140. Further, the communication unit 156 receives a command transmitted from the PC 100 via the connection cable 140 and transfers the received command to the CPU 102.

  The display unit 158 is configured by a liquid crystal display or the like. In the shooting mode, the display unit 158 displays an image of the image data generated by the imaging unit 162. In the reproduction mode, the display unit 158 displays an image of the image data reproduced by the recording unit 166 from the recording medium.

  The image processing unit 164 performs image processing such as pixel interpolation processing and color conversion processing on the image data output from the imaging unit 162 and the reproduced image data output from the recording unit 166. In addition, the image processing unit 164 performs predetermined arithmetic processing on the image data output from the imaging unit 162 and supplies the result to the CPU 152. Based on the calculation result of the image processing unit 164, the CPU 152 automatically controls the exposure of the imaging unit 162 and the light rain point distance by a TTL (through-the-lens) method.

  The operation unit 160 is a user interface for operating the imaging apparatus 150 and includes a plurality of operation buttons. An instruction from the user is input to the CPU 152 via the operation unit 160. Each operation button of the operation unit 160 includes, for example, a switch or a touch panel. Specifically, the operation unit 160 includes a shutter button, a power button, a start / stop button, a mode change button, a menu button, a cross button, a SET button, and the like. The shutter button has two states, a half-pressed state and a fully-pressed state. The CPU 152 starts shooting preparation processing when the shutter button is half-pressed, and starts shooting processing when the shutter button is fully pressed.

  The power button is a button for instructing the CPU 152 to change the imaging apparatus 150 to a power-on state or a power-off state. The power-on state is a state in which necessary power can be supplied to the entire imaging apparatus 150 from a power source battery (not shown) or an AC power source. The power off state is a state in which the supply of power to a part or all of the imaging apparatus 150 from a power source battery or an AC power source (not shown) is stopped. In the case of having a media lid opening / closing detection means for the recording medium, the CPU 152 changes the imaging device 150 to a power-on state or a power-off state in accordance with the opening / closing detection.

  The start / stop button is a button for instructing the CPU 152 to start and pause recording on a recording medium such as an image generated by the imaging unit 162. The mode change button is a button for instructing the CPU 152 which operation mode the imaging apparatus 150 should apply. The operation modes include a shooting mode, a playback mode, a continuous shooting mode, a bulb shooting mode, and a mirror-up shooting mode.

  The menu button is a button for instructing the CPU 152 to display or hide the menu screen of the imaging apparatus 150. The menu screen includes a menu screen for controlling the imaging device 150 and a menu screen for changing settings of the imaging device 150. These menu screens are stored in the memory 154. Menu items include metadata recording settings for setting metadata to be recorded in an image, date settings for setting a date, and connection destination settings for setting the PC 100 as a connection destination.

  The operation unit 160 includes a play button, a stop button, a pause button, a fast forward button, a rewind button, and the like. These buttons are buttons for instructing the CPU 152 to play (play), stop (pause), fast forward (fast forward), and rewind (rewind) the image recorded on the recording medium. is there.

  The imaging unit 162 includes a distance measurement control unit, an exposure control unit, an A / D conversion unit, an imaging element, a compression / expansion circuit, and an optical system. The optical system is a photographing lens group, and includes a variator lens that raises the magnification of photographing, a focusing lens that adjusts the focal point, a diaphragm that adjusts the amount of photographing light, and the like. The imaging element is an element that converts an optical image transmitted through the optical system into an electric signal, and is composed of, for example, a CCD image sensor or a CMOS image sensor. The A / D conversion unit converts the analog image signal output from the image sensor into digital data, and outputs the digital data to the image processing unit 164. The distance measurement control unit controls the focusing lens of the optical system based on the calculation result of the image processing unit 164. The exposure control unit determines the exposure based on the aperture value and the shutter speed. As described above, the CPU 152 controls the exposure control unit and the distance measurement control unit based on the calculation result of the image processing unit 164. That is, exposure and focal length are controlled by the TTL method.

  The compression / decompression circuit is a circuit that uses the memory 154 to compress and decompress image data by adaptive discrete cosine transform (ADCT) or the like. The compression / decompression circuit compresses the image data in the memory 154 and writes the compressed image data back to the memory 154. The compression / decompression circuit also decompresses the compressed image data in the memory 154 and writes the restored image data back to the memory 154.

  The operation of the shooting preparation process will be described. The shooting preparation process mainly includes an auto focus (AF) process, an automatic exposure (AE) process, and an auto white balance (AWB) process. If there is a flash, flash pre-flash (EF: Electronic Flash) processing is included. In the case where the lens or the imaging device 150 is equipped with an image stabilization function, image stabilization processing is also included.

  The AF processing is processing performed by the imaging unit 162 that detects the in-focus position of the imaging lens of the imaging device 150 and controls the optical system to the in-focus position. This process is performed by obtaining the position of the focus lens group of the optical system in which the high-frequency component output from the image signal generated by the image sensor is the largest. The CPU 152 moves the focus lens group from a position corresponding to infinity to a position corresponding to the closest distance set in each shooting mode while performing the position control of the focus lens group by the distance measurement control unit. During this time, the imaging unit 162 detects the in-focus position. If the in-focus position is detected as a result of the AF process, the CPU 102 stores measurement data and / or setting parameters in the memory 154. Thereby, the AF process ends.

  The AE process is a process performed by the imaging unit 162 that controls the amount of light that passes through the optical system and enters the imaging element. The automatic exposure processing is performed using the exposure control unit until the automatic exposure is determined to be appropriate using the calculation result in the image processing unit 164. When it is determined that the incident light amount of the image sensor is appropriate, the CPU 102 stores measurement data and / or setting parameters in the memory 154. The analog image signal output from the image sensor is converted into digital data by the A / D converter and input to the exposure controller. The exposure control unit divides one screen into a plurality of areas, for example, 16 × 16 areas, integrates RGB signals in each divided area, and provides the integrated value to the CPU 152. The CPU 152 detects the brightness of the subject, that is, the subject brightness based on the integrated value of each area obtained from the exposure control unit, and calculates an exposure value suitable for shooting. The CPU 152 determines an aperture value and a shutter speed according to the obtained exposure value, and controls the image sensor and the optical system based on the aperture value and the shutter speed.

  The EF process is a process performed when the CPU 152 determines that the flash is necessary based on the aperture value and the shutter speed determined by the automatic exposure process. When it is determined that the flash is necessary, the CPU 152 sets a flash flag and charges the flash. Also, AF auxiliary light projection, flash light control, or both may be used in combination.

  The AWB process is a process for obtaining an appropriate color balance of the flash photographed image by obtaining the color temperature of the external light and the ratio of the light quantity of the external light and the flash light from the recorded image. The exposure control unit calculates an average integrated value for each color of the RGB signals for each divided area, and provides the calculation result to the CPU 152. The CPU 152 obtains an integrated value of R, an integrated value of B, and an integrated value of G, obtains an R / G ratio and a B / G ratio for each divided area, and calculates an R / G ratio and an R / G ratio of the B / G ratio. The light source type is determined based on the distribution in the color space of the G axis and the B / G axis. Then, the CPU 152 controls the white balance correction value for the R signal, the G signal, and the B signal according to the determined light source type, and corrects the intensity of each color component.

  As the shooting preparation process, in addition to the process described above, a process that is preferably executed before the shooting process may be executed as the shooting preparation process. Further, the AWB process may be performed between the shooting preparation process and the shooting process.

  In the photographing process, the analog image signal output from the image sensor is converted into digital data by the A / D converter, then compressed by the image processor 164, and recorded on the recording medium by the recording unit 166.

  FIG. 5 shows an operation flowchart of the PC 100. With reference to FIG. 5, an operation in which the PC 100 remotely controls the imaging device 150 will be described. A computer program corresponding to the processing shown in FIG. The CPU 102 implements the processing shown in FIG. 5 by executing a computer program stored in the memory 104. The process illustrated in FIG. 5 is executed when the PC 100 and the imaging device 150 are connected via the connection cable 140 and the PC 100 and the imaging device 150 are in the power-on state.

  In step S <b> 501, the CPU 102 determines whether a confirmation command has been received from the imaging device 150 on the camera control screen 300 illustrated in FIGS. 3 and 4. If the confirmation command is received, the CPU 102 proceeds to S509. When the confirmation command is not received, the CPU 102 determines whether or not the metadata registration button 404, the metadata deletion button 406, or the shutter button 306 is clicked by the mouse cursor 312 in S502, S504, and S506.

  When the metadata registration button 404 is clicked in S502, in S503, the CPU 102 generates a metadata registration command. When the metadata deletion button 406 is clicked in S504, the CPU 102 generates a metadata deletion command in S505. When the shutter button 306 is clicked in S506, the CPU 102 generates a shooting command in S507. If the shutter button 306 is not clicked in S506, the CPU 102 returns to S501.

  In step S <b> 508, the CPU 102 transmits the command generated in steps S <b> 503, S <b> 505, and S <b> 506 to the imaging device 150 via the communication unit 106.

  When a confirmation command is received from the imaging apparatus 150 in S501, in S509, the CPU 102 determines whether the confirmation command received in S501 is a metadata registration confirmation command. In the case of a metadata registration confirmation command, the CPU 102 proceeds to S510, otherwise proceeds to S511. In S510, the CPU 102 generates a menu setting command for instructing metadata recording (recording metadata), and the process proceeds to S515.

  In step S511, the CPU 102 determines whether the confirmation command received in step S501 is a metadata deletion confirmation command. In the case of the metadata deletion confirmation command, the CPU 102 proceeds to S512, otherwise proceeds to S513. In S512, the CPU 102 generates a menu setting command for instructing metadata non-recording (metadata is not recorded), and the process proceeds to S515.

  In S516, the CPU 102 determines whether or not an end event such as communication disconnection or power off has occurred. If the end event occurs, the flow shown in FIG. 5 is ended. If not, the process returns to S501 to repeat the process.

  As described above, the PC 100 can generate a camera command having a content corresponding to the confirmation command sent from the imaging device 150, transmit the generated camera command to the imaging device 150, and display an image from the imaging device 150.

  6A and 6B show operation flowcharts of the imaging apparatus 150. FIG. With reference to FIG. 6, the operation of the imaging apparatus 150 under the control of the PC 100 will be described. A computer program corresponding to the processing shown in FIGS. 6A and 6B is stored in the memory 154. The CPU 152 implements the processing shown in FIGS. 6A and 6B by executing a computer program stored in the memory 154. The processing illustrated in FIGS. 6A and 6B is executed when the PC 100 and the imaging device 150 are connected via the connection cable 140 and the PC 100 and the imaging device 150 are in the power-on state.

  In step S <b> 601, the CPU 152 determines whether a camera command has been received from the PC 100. When the camera command is received, the CPU 152 proceeds to S602. When the camera command is not received, the CPU 152 proceeds to S613 (FIG. 6B).

  In step S602, the CPU 152 determines whether the camera command received in step S601 is a metadata registration command. In the case of a metadata registration command, the CPU 152 proceeds to S603, otherwise proceeds to S604.

  In step S606, the CPU 152 determines whether the camera command received in step S601 is a metadata recording menu setting command. In the case of a menu setting command for metadata recording, the CPU 152 proceeds to S607, and otherwise proceeds to S608. In step S607, the CPU 152 changes the metadata recording setting to “record”, and the process advances to step S612.

  In step S608, the CPU 152 determines whether the camera command received in step S601 is a metadata non-recording menu setting command. In the case of a menu setting command without metadata recording, the CPU 152 proceeds to S609, otherwise proceeds to S610. In step S609, the CPU 152 changes the metadata recording setting to “non-recording”, and the process advances to step S612.

  In step S610, the CPU 152 determines whether the camera command received in step S601 is a shooting command. In the case of a shooting command, the CPU 152 proceeds to S611, otherwise returns to S601. In S611, the CPU 152 executes shooting processing, and proceeds to S612. Details of the photographing process will be described later with reference to FIG.

  In S612, the CPU 152 returns a confirmation command to the PC 100 via the communication unit 156 as a response to the processing result for the camera command received in S601. The CPU 152 transmits the captured image of the shooting process (S611) to the PC 100 together with the confirmation command.

  In S630, the CPU 152 determines whether or not an end event such as communication disconnection or power off has occurred. If an end event has occurred, the process shown in FIGS. 6A and 6B is terminated. If not, the process returns to S601 and the process is repeated.

  In S613, the CPU 152 determines whether or not the shutter button is half-pressed. When half-pressed, the CPU 152 proceeds to S614, otherwise proceeds to S617. In step S614, the CPU 152 performs distance measurement and distance measurement by shooting preparation processing. In S615, the CPU 152 determines whether or not the shutter button has been fully pressed. If it is fully pressed, the CPU 152 proceeds to S616, and if not fully pressed, returns to S613. In S616, the CPU 152 performs shooting by shooting processing, and returns to S613.

In step S <b> 617, the CPU 152 determines an operation for menu setting by the operation unit 160. If the operation is to change the metadata recording setting to “non-recording”
The CPU 152 proceeds to S618, and if the metadata recording setting is to be changed to “recording”, the CPU 152 proceeds to S619. In S618, the CPU 152 changes the metadata recording setting to “non-recording” and returns to S601 (FIG. 6A).

  In step S <b> 619, the CPU 152 confirms whether metadata is stored in the memory 154. When there is metadata in the memory 154, the CPU 152 proceeds to S620, and when there is no metadata, the CPU 152 proceeds to S621. In step S620, the CPU 152 changes the metadata recording setting to “recording”. Thereby, the metadata stored in the memory 154 is recorded on the recording medium in association with the photographed image. After S620, the CPU 152 returns to S601 (FIG. 6A).

  In S621, the CPU 152 displays a warning message indicating that the metadata to be recorded in association with the captured image is not stored in the memory 154, and proceeds to S622. The warning in S621 allows the user to recognize that the metadata has not been registered, and prompts the user to register metadata from the PC 100. In S622, the CPU 152 cancels the menu setting metadata recording setting changing operation, keeps the metadata recording setting “non-recording”, and returns to S601 (FIG. 6A).

  FIG. 7 shows a detailed flowchart of photographing (S611, S616). A computer program corresponding to the process shown in FIG. 7 is stored in the memory 154. The CPU 152 implements the processing shown in FIG. 7 by executing the computer program stored in the memory 154.

  In step S <b> 701, the CPU 152 controls the imaging unit 162 to execute shooting processing. That is, exposure is performed, and an analog image signal output from the image sensor is converted into digital data by the A / D conversion unit, and then compressed by the image processing unit 164 and controlled to be recorded on the recording medium by the recording unit 166. .

  In step S <b> 702, the CPU 152 determines whether the metadata recording setting that is one item of the menu setting stored in the memory 154 is “recording” or “non-recording”. If the metadata recording setting is “recording”, the CPU 152 proceeds to S703, and if it is “non-recording”, the process proceeds to S705.

  In step S <b> 703, the CPU 152 uses the metadata stored in the memory 154 to generate metadata to be recorded in association with the image file (recording metadata).

  In S704, the CPU 152 holds the metadata stored in the memory 154 without deleting it. Similarly, the CPU 152 also holds metadata recording settings stored in the memory 154. Thereby, the metadata stored in the memory 154 can be recorded in association with a plurality of subsequent captured images.

  In S705, the CPU 152 instructs the recording unit 166 to record the captured image obtained in S701 on the recording medium as an image file. When the metadata recording setting is “recording”, the recording unit 166 records the recording metadata generated in S703 on the recording medium in association with the photographed image as attribute information.

  As described above, when a camera command for metadata registration / deletion is transmitted from the PC 100 to the imaging apparatus 150, the imaging apparatus 150 performs registration / deletion of metadata, and transmits the result of metadata registration / deletion to the PC 100 as a confirmation command. . When the PC 100 displays or outputs the content of the received confirmation command, the user of the PC 100 can confirm the processing result of the metadata registration / deletion in the imaging device 150. That is, the metadata recording setting of the imaging device can be changed from the PC 100 that is a remote control device.

  In the process shown in FIG. 6A, a metadata recording setting change process (S607, S609) is provided separately from the metadata registration / deletion process (S603, S605). The metadata recording setting change process may be linked to the above. In other words, in response to the camera command for metadata registration, the metadata is stored in the memory 154 and the metadata recording setting is changed to “record”. Further, in response to a camera command for deleting metadata, the metadata is deleted from the memory 154 and the metadata recording setting is changed to “non-recording”. At this time, in the flow shown in FIG. 6B, the processing of S510 and S512 can be omitted.

  A change operation for determining whether or not metadata file recording is appropriate in the imaging apparatus 150, displaying a warning in a fixed case, and prompting re-registration of metadata will be described. FIG. 8 is an operation flowchart of a changed portion of the imaging apparatus 150 and corresponding to FIG. 6A. A computer program corresponding to the processing shown in FIG. 8 is stored in the memory 154. The CPU 152 implements the processing shown in FIG. 8 by executing a computer program stored in the memory 154.

  Since the processes of S801 to S810, S812, and S813 correspond to the processes of S601 to S610, S612, and S630, respectively, detailed description thereof is omitted.

  In S <b> 821 following S <b> 803, the CPU 152 determines whether metadata recording management information is stored in the memory 154. If the metadata recording management information is in the memory 154, the CPU 152 proceeds to S612, and if not, proceeds to S822. In S822, the CPU 152 stores the metadata recording management information in the memory 154.

  The metadata record management information is a type or list of data to be recorded as metadata. For example, there are a media exchange flag, a power-off flag, metadata creation date / time, last shooting date / time, total shooting count, total shooting time, date setting change flag, connection destination, connection destination change count, and GPS positioning position.

  The media exchange flag is information for managing opening / closing of the media lid. When the CPU 152 detects opening / closing of the media lid, it sets a media replacement flag.

  The power OFF flag is information for managing whether or not the power is turned off by pressing the power button. When the CPU 152 detects a pressing operation of the power button by the user, the CPU 152 sets a power OFF flag.

  The metadata creation date and time indicates the creation date and time when metadata record management information is newly created.

  The last shooting date and time is information indicating the last date and time when the shooting process was performed. When instructing the photographing process in the imaging unit 162, the CPU 152 updates the current time with the last photographing date and time.

  The total number of times of photographing is information representing the number of times of photographing after newly creating metadata record management information. When instructing the photographing process in the imaging unit 162, the CPU 152 increments the total number of photographing by one.

  The total shooting time is information indicating the time taken after the metadata record management information is newly created. When the shooting interval is within a certain time, it is considered that the shooting action is continued, and the continued time is treated as the shooting time. CPU152 measures the time interval of each imaging | photography process in the imaging part 162, and when the fixed time is exceeded, the imaging | photography time is added to the continuation time until then.

  The date setting change flag is information for managing whether or not date setting has been performed by a menu button operation. When the CPU 152 detects execution of date setting, it sets a date setting change flag.

  The connection destination is information representing the connection destination in the connection destination setting. The connection destination may be a host name, IP address or network address of the PC 100. The CPU 152 updates the connection destination information in the memory 154 according to the connection destination setting.

  The connection destination change count is information indicating the number of times the connection destination setting has been changed. When the connection destination change count recorded in the memory 154 is changed, the CPU 152 counts up the connection destination change count by one.

  The GPS positioning position is information representing a positioning position acquired from a GPS device. When the positioning position of the GPS device can be acquired through the communication unit 156, the CPU 152 periodically receives the positioning information of the GPS device through the communication unit 156 and updates the GPS positioning position.

  In S823 following S805, the CPU 152 deletes the metadata recording management information stored in the memory 154 from the memory 154.

  As described above, in the flow shown in FIG. 8, the CPU 152 stores the metadata from the PC 100 in the memory 154 and registers the metadata recording management information in accordance with the metadata registration instruction from the PC 100. Further, the CPU 152 deletes the metadata and the metadata recording management information from the memory 154 in accordance with the metadata deletion instruction from the PC 100.

  The shooting process (S811) is slightly different from the shooting process of S611, but the details will be described with reference to FIG.

  In S824 following S811, the CPU 152 refers to the metadata record management information in the memory 154 to determine whether the metadata record is valid. If the metadata recording is valid, the CPU 152 proceeds to S812, and if invalid, the process proceeds to S825. In step S825, the CPU 152 displays a warning indicating that the metadata stored in the memory 154 is invalid on the display unit 158. This warning display allows the user to recognize that the metadata is invalid. That is, it becomes possible to prompt the user to re-register metadata from the PC 100.

  FIG. 9 shows a detailed flowchart of the photographing process (S811). A computer program corresponding to the processing shown in FIG. 9 is stored in the memory 154. The CPU 152 implements the processing shown in FIG. 9 by executing a computer program stored in the memory 154.

  In step S901, the CPU 152 controls the imaging unit 162 to execute shooting processing, as in step S701. That is, exposure is performed, and an analog image signal output from the image sensor is converted into digital data by the A / D conversion unit, and then compressed by the image processing unit 164 and controlled to be recorded on the recording medium by the recording unit 166. . In S902, the CPU 152 determines whether the metadata recording setting, which is one item of menu setting stored in the memory 154, is “recording” or “non-recording”, as in S702. When the metadata recording setting is “recording”, the CPU 152 proceeds to S903, and when it is “non-recording”, the process proceeds to S907.

  In step S903, the CPU 152 determines whether the metadata recording management information is valid or invalid. This determination processing is processing for determining whether or not the imaging device 150 shows a certain change for each item of the metadata record management information, and details thereof will be described later with reference to FIG. If the metadata recording management information is valid as the determination result of S903, the CPU 152 proceeds to S905, and if invalid, the process proceeds to S907.

  In S905, the CPU 152 uses the metadata stored in the memory 154 to generate metadata (recording metadata) to be recorded in association with the image file, similarly to S703.

  In S906, the CPU 152 retains the metadata stored in the memory 154 without deleting, as in S704. Similarly, the CPU 152 also holds metadata recording settings stored in the memory 154. Thereby, the metadata stored in the memory 154 can be recorded in association with a plurality of subsequent captured images.

  In step S907, the CPU 152 instructs the recording unit 166 to record the captured image obtained in step S901 on the recording medium as an image file. When the metadata recording setting is “record” (S902) and the metadata recording management information is valid (S904), the recording unit 166 records the recording metadata generated in S905 in association with the photographed image. Record on media.

  As described above, according to the processing shown in FIG. 9, when the metadata recording management information is valid, the metadata is recorded on the recording medium in association with the photographed image. Even if the metadata recording setting is “recording”, the metadata is not recorded if the metadata recording management information is invalid.

  FIG. 10 shows a detailed flowchart of the metadata record management information determination (S903). A computer program corresponding to the processing shown in FIG. 10 is stored in the memory 154. The CPU 152 implements the processing shown in FIG. 10 by executing a computer program stored in the memory 154. In FIG. 10, the CPU 152 functions as a change detection unit that detects a change for each item (camera setting) of the metadata record management information, and determines whether the change of each item exceeds a predetermined threshold.

  In step S <b> 1001, the CPU 152 determines whether the media replacement flag of the metadata recording management information recorded in the memory 154 is set. As described above, when the media lid is opened and closed, the CPU 152 sets a media exchange flag. If the media exchange flag is set, the CPU 152 advances to S1012. If the media exchange flag is not set, the CPU 152 advances to S1002. The meta information recording can be switched between valid and invalid depending on whether the media cover is opened or closed.

  In step S <b> 1002, the CPU 152 determines whether the power OFF flag of the metadata recording management information recorded in the memory 154 is set. If the power OFF flag is set, the CPU 152 proceeds to S1012. If the power OFF flag is not set, the CPU 152 proceeds to S1003. Thereby, it is possible to switch between valid and invalid of the metadata recording depending on whether or not the power is turned off.

  In step S <b> 1003, the CPU 152 determines a time difference between the last shooting date / time of the metadata recording management information stored in the memory 154 and the current time held by the CPU 152. If the time difference is less than the certain value, the CPU 152 proceeds to S1004, and if the time difference is greater than or equal to the certain value, the process proceeds to S1012. Accordingly, it is possible to switch between valid and invalid metadata recording depending on whether or not a certain time has elapsed since the last photographing time. In addition, although it determined by the time difference from the last imaging | photography time, you may determine by the time difference from the creation time of metadata recording management information.

  In step S <b> 1004, the CPU 152 determines whether the total number of shootings of the metadata recording management information stored in the memory 154 is greater than or equal to a certain upper limit value. If the total number of shootings is less than a certain value, the CPU 152 proceeds to S1005, and if the total number of shootings is greater than or equal to a certain value, the process proceeds to S1012. Thereby, it is possible to switch between valid and invalid of the metadata recording depending on whether or not the total number of photographing exceeds a certain number.

  In step S <b> 1005, the CPU 152 determines whether the total shooting time of the metadata recording management information stored in the memory 154 is a certain value or more. When the total shooting time is less than the predetermined value, the CPU 152 proceeds to S1006, and when the total shooting time is equal to or more than the predetermined value, the CPU 152 proceeds to S1012. Thereby, it is possible to switch between valid and invalid of the metadata recording depending on whether or not the total photographing time exceeds a certain time.

  In step S <b> 1006, the CPU 152 determines whether the date setting change flag of the metadata recording management information stored in the memory 154 is set. If the date setting change flag is not set, the CPU 152 proceeds to S1007, and if the date setting change flag is set, the process proceeds to S1012. Accordingly, it is possible to switch between valid and invalid of the metadata recording depending on whether or not the time setting is changed.

  In step S <b> 1007, the CPU 152 determines the connection destination of the metadata record management information stored in the memory 154. If the information of the PC 100 as the connection destination matches, the CPU 152 advances to S1008, and if not, advances to S1012. Accordingly, it is possible to switch between valid and invalid metadata recording depending on whether the connection destination is correct.

  In step S1008, the CPU 152 determines whether the connection destination change count of the metadata record management information stored in the memory 154 is equal to or greater than a predetermined value. If the connection destination change count is less than the predetermined value, the CPU 152 advances to S1008, and if the connection destination change count is equal to or greater than the predetermined value, the CPU 152 advances to S1012. Accordingly, it is possible to switch between valid and invalid of the metadata recording depending on whether or not the number of times of changing the connection destination is a certain number or more.

  In S1009, the CPU 152 determines whether or not the positioning position of the GPS device can be acquired by the communication unit 156. If the positioning position of the GPS device cannot be acquired, the CPU 152 proceeds to S1012. If it can be acquired, the CPU 152 proceeds to S1010. Thereby, the validity and invalidity of metadata recording can be switched depending on whether or not the positioning position of the GPS device can be acquired.

  In step S <b> 1010, the CPU 152 determines a distance (movement distance) between the GPS positioning position of the metadata record management information recorded in the memory 154 and the positioning position obtained from the GPS device through the communication unit 156. If the movement distance is less than the predetermined value, the CPU 152 proceeds to S1011. Accordingly, it is possible to switch between valid and invalid of the metadata recording depending on whether or not a certain distance from the last photographed position.

  In step S <b> 1011, the CPU 152 sets validity determination to the return value of the determination result of the metadata recording management information. In S1013, the CPU 152 updates the metadata recording management information recorded in the memory 154. The last shooting date / time is updated with the current time, the total number of shootings is incremented by 1, and the total shooting time is added.

  In S1012, the CPU 152 sets invalidity determination as a return value of the determination result of the metadata recording management information.

  With the processing shown in FIG. 10, the imaging device 150 (CPU 152) can record metadata appropriate for file recording by determining metadata recording management information.

  Further, when the determination result of the metadata record management information stored in the memory 154 is invalid, the CPU 152 displays a warning that the metadata stored in the memory 154 is invalid on the display unit 158. . Thereby, recording of meaningless information can be prevented. Further, a warning display when the metadata file recording is not valid can prompt the user to re-register the metadata.

  In the flow shown in FIG. 10, all of the media replacement flag, power OFF flag, metadata creation date / time, last shooting date / time, total shooting count, total shooting time, date setting change flag, connection destination, connection destination change count, and GPS positioning position are all included. Validity / invalidity is judged by evaluating the value of. However, the validity / invalidity may be determined by evaluating one of these values.

  If the content of the metadata record management information is not valid, the metadata itself may be deleted and the metadata record setting may be changed to “non-record”. That is, in the case of “invalid” in S904, the CPU 152 deletes the metadata from the memory 154 and changes the metadata recording setting to “non-recording”.

  The metadata recorded in association with the photographed image includes essential or default elements such as imaging device identification information, photographing conditions, and photographing positions, and optional or optional elements such as user comments. The present invention is also applicable to the case where the latter optional element recording / non-recording can be selected when the metadata recording setting is “recording”. That is, even when the recording setting of an arbitrary element is “non-recording”, if the content of the arbitrary element has content, the recording setting of the arbitrary element is changed to “recording” and the arbitrary element is recorded.
