Based on the control from the control unit 110, the wireless communication unit 114 transmits and receives data to and from an external device (including the mobile terminal 200) such as a terminal device, an external camera, and a personal computer. The wireless communication unit 114 transmits setting information, operation information, and the like of the imaging apparatus 100, and receives commands that are instructions for operating the imaging apparatus 100, attribute information that is recorded together with image data, and the like. Data that can be transmitted and received includes digital image data and analog video signals. Note that the imaging apparatus 100 may include a wired communication unit that enables wired communication.

  FIG. 2 is a block diagram of the mobile terminal 200. The portable terminal 200 is a terminal device that can be wirelessly connected to the imaging device 100, and is a remote controller or a remote controller that is provided separately from the main body 101. The mobile terminal 200 includes a control unit 221 that controls the entire system of the mobile terminal 200. A display unit 222, an operation unit 223, a wireless communication unit 224, a ROM 225, and a RAM 226 are electrically connected to the control unit 221, and the control unit 221 and each configuration unit can exchange data with each other. .

  The control unit 221 has a CPU, and controls each component by developing the program recorded in the ROM 225 in the RAM 226 and executing it. The ROM 225 is a nonvolatile recording medium and stores a program executed by the control unit 221. The RAM 226 is a volatile recording medium used as a work memory for the control unit 221. The display unit 222 is a display such as a liquid crystal display, and displays various setting states and data (including digital image data and analog video signals) received from the wireless communication unit 224 based on control from the control unit 110.

  The portable terminal 200 may be any device that can transmit a command to the imaging device 100, and the form is not limited. In addition, transmission of commands may be performed by wire regardless of the wireless communication standard.

  3A to 3D are diagrams illustrating display examples of the display unit 115 of the imaging apparatus 100. FIG. The display unit 115 includes an image display region R2 and an end region R1 (R1a, R1b) (predetermined region). In the image display area R2, an image being shot is displayed as a through image (live view image), or an already recorded image is reproduced and displayed. The end region R1 is a region other than the image display region R2, and is arranged at the upper and lower ends of the image display region R2, and displays information other than the captured image. The image display region R2 is a region that is changed according to the aspect ratio of the image to be recorded, and the end region R1 is the remaining region of the display unit 115 excluding the image display region R2. Note that both the end region R1 and the image display region R2 can display various display colors, and can display patterns, characters, figures, and the like different from the captured image. The control unit 110 can generate display data in cooperation with the image processing unit 113 when displaying an image other than the captured image on the display unit 115.

  A recording state item 301 is provided across the image display region R2 and the end region R1a. The recording state item 301 is a square that emits white light during shooting standby, and a circular shape that emits red light during moving image recording. A mode display unit 302 is provided in the image display region R2. The mode display unit 302 displays contents corresponding to various operation modes such as a shooting mode.

  The recording start command (recording start instruction) is received when it is input and accepted by the user through the operation unit 116 of the main body 101, or when it is transmitted from an external device such as the mobile terminal 200 and received by the wireless communication unit 114. There are cases. When receiving the recording start command, the control unit 110 starts moving image shooting. The recording start command is a first instruction for starting the photographing and recording operation among predetermined instructions. Note that the content recorded in response to the recording start command is not limited to a moving image but may be a still image or audio.

  The display modes of the display unit 115 shown in FIGS. 3A, 3B, 3C, and 3D are referred to as modes A, B, C, and D, respectively. Aspect A is a display aspect indicating a photographing standby state. A mode B is a display mode indicating that a moving image is being recorded when a recording start command is received via the operation unit 116 of the main body 101. A mode C is a display mode that indicates that a moving image is being recorded when a recording start command is received via the wireless communication unit 114. A mode D is a display mode when an operation command other than a command related to recording is received via the wireless communication unit 114. Since the entire screen of the display unit 115 has an aspect ratio of 4: 3 and the image to be shot standby is 16: 9, the upper and lower end regions R1 are used as mask regions in this embodiment.

  For example, in the mode A (FIG. 3A) in the shooting standby state, a through image is displayed in the image display region R2, and the end region R1 is a black mask (black display). The recording state item 301 is a white square. It is assumed that the shooting mode is set to auto, and “AUTO” is displayed on the mode display unit 302. In this state, when a recording start command is input from the operation unit 116, the display screen transitions to the mode B (FIG. 3B). In aspect B, the recording state item 301 changes from a white square to a red circle, but the others do not change.

  When a recording start command is transmitted from the operation unit 223 of the portable terminal 200 in the state of the mode B and is received via the wireless communication unit 114, the display mode transitions to the mode C (FIG. 3C). In aspect C, the control unit 110 changes the end region R1 from black to red to indicate that a recording start command has been accepted. The end region R1 is a region along the side of the display unit 115 and indicates a region around the image display region R2, and thus the aspect ratio of the image can be understood by looking at the end region R1. If the color of the end region R1 is set to be conspicuous red even from a distance from black, the user can grasp that recording of a moving image is started with a horizontally long aspect ratio. Further, since the end region R1 has upper and lower regions and both the upper and lower regions are red, the user has started recording (or is recording) from a remote location (for example, near the mobile terminal 200). ) Easy to see. The color may be changed when the command is received or when the function corresponding to the received command is executed. If the image display region R2 is made small so that the end region R1 becomes large only when remote, the display change of the end region R1 can be easily understood. Further, when the user is near the main body, it is easier to check the image if the image display area R2 is enlarged.

  When an operation command (second instruction) other than the command related to recording is transmitted from the operation unit 223 of the portable terminal 200 in the state of the mode A and is received via the wireless communication unit 114, the display screen is changed to the mode D. Transition is made (FIG. 3D). For example, when a command for switching the shooting mode to the program AE mode is received, “P” is displayed in the mode D instead of “AUTO” displayed in the mode A (program). Indicates P). In addition, the control unit 110 indicates to the aspect A that the end region R1 has been changed from black to blue and a command other than recording has been received. Since the upper and lower mask areas turn blue, it is easy for the user to visually recognize that the operation command has been normally received from a remote location (for example, near the mobile terminal 200). Note that the blue display in the end region R1 is temporary, and when the predetermined time has elapsed, the display state immediately before that is returned.

  If any command is received from the user via the operation unit 116 of the main body 101 while the display mode is set to either mode C or D, the display of modes C and D is terminated. The camera enters the shooting standby state. When the display mode is set to mode C and the recording end command, which is an instruction to cancel the recording operation, is received via the wireless communication unit 114 or the operation unit 116 of the main body 101, the display of mode C is displayed. Ends and the display mode transitions to mode A. Regarding the display mode of the display unit 115, when focusing only on the image display region R2 and the end region R1, modes A and B are the same mode. Aspects A and B are the first aspect. Aspect C is the second aspect, and Aspect D is the third aspect.

  Of the display areas of the display unit 115, the area where the item 301 is displayed is the “first area” in the present invention. The end region R1 corresponds to a “second region” larger than the first region. In addition, the “second region” may include the image display region R2 in addition to the end region R1, and may further include the item 301.

  FIG. 4 is a flowchart of the display control process of the display unit 115. The processing of this flowchart is realized by the control unit 110 reading the program stored in the ROM 117 into the RAM 118 and executing it. This process is started when the power of the imaging apparatus 100 is turned on, and then repeatedly executed at predetermined time intervals.

  First, the control unit 110 determines whether or not a command has been received from the mobile terminal 200 or the main body 101 (step S401). When the command is received, the source of the command is the main body 101 (the operation unit 116). It is discriminate | determined (step S402). When the command source is the main body 101, the control unit 110 controls the display mode of the display unit 115 to be the mode A or the mode B (step S403). Specifically, if the command from the main body 101 is a command other than the recording start command, the mode A (FIG. 3A) is used, and if the command is a recording start command, the mode B (FIG. 3B) is set. Therefore, for example, when a command is received from the main body 101 while the display mode is set to either mode C or D, the display of modes C and D ends. In addition, in step S403, the control unit 110 performs processing according to the accepted command. That is, if the command is the start of recording, the control unit 110 starts recording on the main body 101 side, and if it is another command such as mode switching, performs processing according to the received instruction such as mode switching. Thereafter, the process of FIG. 4 ends.

  On the other hand, if it is determined in step S402 that the command source is not the main body 101, the command is received and accepted by the wireless communication unit 114, and the command source is the portable terminal 200. Therefore, control unit 110 determines whether or not the accepted command is a recording start command (step S404). If the received command is a recording start command, the control unit 110 controls the display mode of the display unit 115 to be the mode C (FIG. 3C) (step S405). Thereafter, the process of FIG. 4 ends.

  On the other hand, as a result of the determination in step S404, if the accepted command is not a recording start command, the control unit 110 determines whether or not the accepted command is a recording end command (step S406). If the accepted command is a recording end command, the control unit 110 controls the display mode of the display unit 115 to be the mode A (FIG. 3A) (step S407). Therefore, for example, when the recording end command is received via the wireless communication unit 114 while the display mode is set to mode C, the display of mode C is ended and the mode transitions to mode A. Thereafter, the process of FIG. 4 ends.

  On the other hand, if the received command is not a recording end command as a result of the determination in step S406, it is another command such as mode switching. Therefore, the control unit 110 controls the display mode of the display unit 115 to be the mode D (FIG. 3D) unless the image is being recorded (step S408). It should be noted that since the mode switching command is not accepted during image recording, the control unit 110 does not perform the transition process to the mode D in step S408 when the image is being recorded. Thereafter, the process of FIG. 4 ends. Accordingly, the user can visually recognize that an instruction other than recording is normally transmitted to the imaging apparatus 100 and responded. If the command is not accepted as a result of the determination in step S401, the control unit 110 determines whether or not the current display mode of the display unit 115 is the mode D (step S409), and the display mode is not the mode D. In that case, the process of FIG. 4 is terminated. On the other hand, when the current display mode of display unit 115 is mode D, control unit 110 determines whether or not a predetermined time has elapsed since the display mode finally changed to mode D (step S410). Note that the timing of the predetermined time is started in step S408. And control part 110 ends processing of Drawing 4, when predetermined time has not passed since the display mode became mode D last.

  On the other hand, when the predetermined time has elapsed, the control unit 110 changes the display mode of the display unit 115 to the mode A. Since the mode switching instruction is not accepted during recording, the recording is not being performed in the state D. Therefore, when the predetermined time has elapsed, the process returns to the state A indicating that the apparatus is on standby. Here, the process of FIG. 4 ends.

  According to the present embodiment, control unit 110 accepts commands by receiving commands from outside via wireless communication unit 114 in addition to accepting commands by operation unit 116 of main body 101. When the recording start command (first instruction) is received by the main body 101, the control unit 110 changes the display mode of the display unit 115 to mode B (first mode) and is received by the wireless communication unit 114. Is referred to as aspect C (second aspect).

  In the mode B, the item 301 (first area) becomes a red circle to indicate that the recording start is instructed. In the aspect C, the end region R1 (second region) turns red to indicate that the recording start is instructed. The end region R1 is larger than the item 301. That is, even if the command is the same, the area of the display unit 115 where the display form changes is larger when it is received from the wireless communication unit 114 than when it is received from the main body 101. Thereby, the user who instructed the main body 101 with the portable terminal 200 (remote control) can recognize more accurately whether the main body 101 received the instruction.

  Furthermore, since the display form of the area indicating the image aspect ratio in the display unit 115 is changed, the user has received an instruction regarding the image, and how much aspect ratio is being shot. Easy to grasp. Therefore, since the change in the display form of the display unit 115 can be easily understood from a user who is far away, it is easy to recognize that the given instruction is transmitted.

  Further, when another operation command (second instruction) different from the recording start command, for example, a shooting mode switching command is received by the wireless communication unit 114, the display mode of the display unit 115 becomes the mode D. Here, when another operation command is received by the main body 101, the display mode of the display unit 115 is the mode A or the mode B, which is different from the mode D. Accordingly, it is possible to easily confirm the response state corresponding to other operation commands.

  In the modes A to D, the end regions R1a and R1b that are the upper and lower ends of the display unit 115 are exemplified as the predetermined region where the display mode is changed except for the image display region R2. However, the present invention is not limited thereto. For example, depending on the aspect ratio, the end region R1 is a region at both the left and right ends of the display unit 115 (a region along the left and right sides). Further, the end region R1 may be formed into a frame shape by reducing the image display region R2, and the display form of the frame may be changed when a command is received. That is, the end region R1 is a region surrounding the display image. In this case, even when the aspect ratio of the image and the display unit 115 matches, the control unit 110 does not display the image so that the length of either the vertical or horizontal direction of the display unit 115 matches one side of the image, and the frame is not The image may be displayed slightly smaller so that it is possible. Further, even if the aspect ratio of the image is not the same as the aspect ratio of the display unit 115, the image display region R2 may always be changed to be smaller (the aspect ratio remains the same) so that the end region R1 becomes larger. As described above, when an image having a predetermined aspect ratio is displayed on the display unit 115, the control unit 110 reduces the area where the image is displayed in response to the command received by the wireless communication unit 114. . Further, the control unit 110 performs control so as to display that a predetermined instruction has been given, with an area other than the area where the image is displayed surrounding the image as the second area.

  The end region R1 may be a partial region such as a corner in the image display region R2. The number of predetermined regions may be one, or may be three or more. In addition, when a plurality of predetermined regions are used, it is not essential to set them to a common display color. Aspects A and B, and aspects C and D are different from each other depending on combinations of different display colors and patterns. You may make it become. Furthermore, the item 301 may be enlarged and displayed on the entire surface of the display unit 115. In other words, when it is not a remote instruction, the control unit 110 displays the item 301 in a normal size so as not to overlap the image, and when it is a remote instruction, the item 301 is enlarged and displayed on the image. Like that.

  Further, the display colors used in the predetermined area are not limited to the illustrated black, red, and blue. Furthermore, the change of the display mode in the predetermined area is not limited to the display color, and may be a pattern to be displayed, a mark, presence / absence of blinking, or the like. The display color includes a color that is visually recognized without light emission.

  Further, when a remote instruction is given, the mode C or D may be displayed, and the luminance of the display unit 115 may be increased so that the display on the display unit 115 is more noticeable. The luminance of the display unit 115 may be increased during recording, or may be decreased when a predetermined time such as 10 seconds or 20 seconds elapses. In the case of a mode switching instruction, it may be lowered according to the elapse of a predetermined time.

(Second Embodiment)
FIGS. 5A and 5B are diagrams showing a display example of the display unit 115 according to the second embodiment of the present invention. In the present embodiment, modes C and D among the display modes of the display unit 115 are different from those of the first embodiment. The aspects A and B and other configurations are the same as those in the first embodiment. That is, with respect to aspect C (second aspect) and aspect D (third aspect), those shown in FIGS. 5 (a) and 5 (b) instead of those shown in FIGS. Adopted.

  In the aspect C (FIG. 5A), the through image is not displayed in the image display region R2, and not only the end region R1 but also the image display region R2 is displayed in red. Others are the same as those shown in FIG. Since the entire screen turns red, the user can more easily recognize that recording has started from a remote location (for example, near the mobile terminal 200). On the other hand, in the aspect D (FIG. 5B), the through image is not displayed in the image display region R2, and not only the end region R1 but also the image display region R2 is displayed in blue. Since the entire screen turns blue, it is easy for the user to visually recognize that the operation command has been normally received from a remote location (for example, near the mobile terminal 200). At this time, a line indicating the aspect ratio may be displayed to indicate the aspect ratio of the image.

  According to the present embodiment, a user who gives an instruction to the main body of the apparatus with the remote controller can recognize more accurately whether the main body has received the instruction, and the same effect as in the first embodiment can be obtained. Can play. In addition, since the entire screen of the display unit 115 changes to red or blue, the visibility is improved, and the response state can be confirmed more easily.

  In the present embodiment, in modes C and D, the display mode of the image display region R2 is the same as that of the end region R1, but can be clearly distinguished from the display of the through image as in modes A and B. It is sufficient if it is an aspect, and it does not need to be the same. Further, it is not essential to use the entire screen of the display unit 115 when changing the display color.

(Third embodiment)
FIG. 6 is a part of a flowchart of display control processing of the display unit 115 according to the third embodiment of the present invention. The processing of this flowchart is obtained by adding steps to the flowchart of FIG. 4, and the execution requirements and start conditions are the same as those described in FIG. In FIG. 6, illustration of steps S401 to S408 and specific illustration of steps S410 to S411 are omitted. This embodiment can be applied to both the first and second embodiments. Therefore, when applied to the first embodiment, modes C and D are considered as shown in FIGS. 3C and 3D, and when applied to the second embodiment, modes C and D are used. Can be considered as shown in FIGS. 5 (a) and 5 (b).

  The processing in steps S401 to S408 (not shown) is as described in FIG. The processing in step S409 is also as described in FIG. As a result of the determination in step S409, if the current display mode of the display unit 115 is mode D, the control unit 110 executes steps S410 to S411 in FIG. 4 and ends the display control process. When the display mode of the current display unit 115 is not the mode D, the control unit 110 determines whether an error is being received (whether an error has been detected) (step S601). Errors (events to be warned) here include events that cannot continue normal operation, for example, events that cannot start or continue recording (media full, media write error, buffer over, battery low) included.

  If no error is being received (no event to be warned), the control unit 110 ends the display control process. On the other hand, if an error is being received, control unit 110 waits for a predetermined time to elapse (step S602), and then whether or not the current display mode of display unit 115 is mode A or mode B. Is determined (step S603). The fixed time is, for example, 3 seconds or 4 seconds. If the display mode of the current display unit 115 is mode A or mode B, the control unit 110 controls the display mode of the display unit 115 to be mode C (step S604). On the other hand, when the display mode of the current display unit 115 is neither mode A nor mode B, the display mode is mode C, so the control unit 110 changes the display mode of the display unit 115 to mode A or mode B. Control is performed to either one (step S605). Specifically, the control unit 110 changes the display mode to mode B if recording is being continued, and mode A if recording is not being continued. After steps S604 and S605, the display control process ends.

  Therefore, when an error occurs while the display mode of the display unit 115 is any of modes A, B, and C, the display mode is the first mode (mode A or mode B) and the second mode. The mode (mode C) is alternately switched at a constant time interval.

  According to the present embodiment, a user who gives an instruction to the main body of the apparatus with the remote controller can recognize more accurately whether the main body has received the instruction, and the same effect as in the first embodiment can be obtained. Can play. In addition, while the error is being accepted, the display mode of the display unit 115 is periodically switched between modes A, B, and C, so that a visual effect such as blinking can be exhibited, and the occurrence of an error can be confirmed from a remote location. It becomes easy. When the error is accepted, the display form for alternately displaying may not be the forms A, B, and C, but may be other forms.

  By the way, in each said embodiment, the portable terminal 200 receives a picked-up image from the imaging device 100, and displays it on the display part 222. FIG. Therefore, even if it is not possible to confirm the shooting screen on the imaging apparatus 100 side, confirmation on the portable terminal 200 side is possible.

  In each of the above embodiments, the mobile terminal 200 is exemplified as the command transmission source, but the present invention is not limited to this. For example, a remote control device for remote operation manufactured along with the imaging device 100 may be used.

  Note that the imaging apparatus 100 may be configured to accept commands from the infrared remote controller. When a command is received from the infrared remote controller, it may be handled in the same manner as when a command is received from the outside by the wireless communication unit 114. However, it is preferable to handle the command in the same manner as when a command is received by the operation unit 116 of the main body 101. This is often used in situations where the infrared remote controller generally does not have a function for receiving and displaying captured images and the user does not want to touch the camera directly (such as avoiding the camera moving when the shutter is on). Therefore, it is normal to check the image on the camera side. Although the recording start command is exemplified as the first instruction and the shooting mode switching command is exemplified as the second instruction, the command is not limited to these commands.

  Note that the processing of the flowchart of FIG. 4 (including FIG. 6) has been described as being performed by the control unit 110, but the above-described various controls may be performed by one hardware, or a plurality of hardware processes. The entire apparatus may be controlled by sharing.
