     First Embodiment 
     In the first embodiment, as an example of the imaging apparatus according to the present disclosure, a box-type digital camera not including a display in the own apparatus will be described. 
     1. Configuration 
     A configuration of a digital camera according to the first embodiment will be described with reference to  FIGS.  1  to  2   .  FIG.  1    is a diagram for illustrating an overview of a digital camera  10  according to the present embodiment. 
     The digital camera  10  of the present embodiment is configured to be connectable to various external apparatuses in, for example, a box-shaped apparatus body. With this digital camera  10 , it is possible for the user to easily perform extension or the like on desired functions. 
       FIG.  1    illustrates a state in which a monitor  30  in an external configuration is connected to the digital camera  10  of the present embodiment via a communication cable. The digital camera  10  of the present embodiment is not particularly provided with a monitor, a viewfinder, or the like in the apparatus body. When desiring to check a live view image captured in real time by the digital camera  10 , a setting menu, or the like, the user connects the external monitor  30  to the digital camera  10  to cause the external monitor  30  to perform desired display, for example. In addition, the digital camera  10  is, an interchangeable lens type, and is configured so that the interchangeable lens  20  can be mounted, for example. 
     1-1. Configuration of Digital Camera 
       FIG.  2    is a diagram showing a configuration of a digital camera  10  according to the present embodiment. The digital camera  10  of the present embodiment includes a mount  120  for the interchangeable lens  20 , an image sensor  140 , a user interface  150 , an image processor  160 , a buffer memory  170 , and a controller  180 , for example. Furthermore, the digital camera  10  includes a flash memory  130 , a card slot  190 , and various connection terminals  110 ,  112 , and  114 . The various connection terminals  110  to  114  include an HDMI terminal  110 , an SDI terminal  112 , and a USB terminal  114 , for example. 
     The interchangeable lens  20  includes an optical system such as a zoom lens, a focus lens, and a diaphragm, a driver, and the like. The zoom lens is a lens for changing the magnification of the subject image formed by the optical system. The focus lens is a lens for changing the focus state of the subject image formed on the image sensor  140 . The zoom lens and the focus lens are formed of one or more lenses. 
     The driver of the interchangeable lens  20  includes configurations each for driving a corresponding one element of the optical system, such as the focus lens. For example, the driver of the focus lens includes a motor, and moves the focus lens along the optical axis of the optical system under the control of the controller  180 . The configuration for driving each element of the optical system in the driver of the interchangeable lens  20  can be achieved by a DC motor, a stepping motor, a servo motor, an ultrasonic motor, or the like. 
     The mount  120  is an attachment unit for detachably mounting the interchangeable lens  20  in the digital camera  10 . The mount  120  includes an interface circuit that performs various data communication between the digital camera  10  and the interchangeable lens  20 . 
     The image sensor  140  captures a subject image incident via the optical system of the interchangeable lens  20  to generates RAW data, for example. The RAW data is an example of image data in RAW format corresponding to a state of an imaging result by the image sensor  140 . For example, the RAW data includes information on the light quantity exposed for each pixel in the Bayer array, and indicates an image of an imaging result. The image sensor  140  performs an imaging operation of an image constituting each frame of a moving image, for example. The image sensor  140  is an example of an image sensor in the present embodiment. 
     The image sensor  140  generates RAW data of a new frame at a predetermined frame rate (e.g., 30 frames/sec). The RAW data generation timing and the electronic shutter operation in the image sensor  140  are controlled by the controller  180 . As the image sensor  140 , various image sensors such as a CMOS image sensor, a CCD image sensor, or an NMOS image sensor can be used. 
     The user interface  150  is a general term for operation members that receive an operation (instruction) from a user. The user interface  150  includes buttons, levers, dials, switches, and the like that receive user operations. A specific example of the user interface  150  will be described below. 
     The image processor  160  performs predetermined processing on the RAW data output from the image sensor  140  to generate image data of a shooting result. For example, the image processor  160  may perform processing for development and may generate an image to be displayed on the external monitor  30  or the like. Examples of the predetermined processing include debayer processing, white balance correction, gamma correction, YC conversion processing, electronic zoom processing, compression processing, expansion processing, and the like, but are not limited thereto. The image processor  160  may be configured with a hard-wired electronic circuit, or may be configured with a microcomputer, a processor, or the like using a program. 
     The buffer memory  170  is a recording medium that functions as a work memory for the image processor  160  and the controller  180 . The buffer memory  170  is implemented with a dynamic random-access memory (DRAM) or the like. The flash memory  130  is a non-volatile recording medium. Each of the memories  130  and  170  is an example of a storage in the present embodiment. 
     The controller  180  controls the operations whole of the digital camera  10 . The controller  180  uses the buffer memory  170  as a work memory during a control operation or an image processing operation. 
     The controller  180  includes a CPU or an MPU, and the CPU or MPU implements a predetermined function by executing a program (software). The controller  180  may include a processor including a dedicated electronic circuit designed to achieve a predetermined function instead of the CPU or the like. That is, the controller  180  can be implemented with various processors such as a CPU, an MPU, a GPU, a DSU, an FPGA, and an ASIC. The controller  180  may include one or more processors. 
     The card slot  190  can mount the memory card  200 , and accesses the memory card  200  based on the control from the controller  180 . The digital camera  10  can record image data in the memory card  200  and read the recorded image data from the memory card  200 . 
     In the present embodiment, an example in which the external monitor  30  is connected to the HDMI terminal  110  of the digital camera  10  will be described. The external monitor  30  is an example of an external apparatus that displays an image and the like. The external monitor  30  has a function of performing development processing on an image of RAW data input from the digital camera  10  in a displayable manner, for example. In addition, the external monitor  30  may have a recorder function of recording, for example, moving image data or the like indicating a displayed image in a recording medium. 
     In the digital camera  10 , the HDMI terminal  110  is a connection terminal connected to an external apparatus such as the external monitor  30  via, for example, a communication cable and for outputting a digital signal such as an image signal in data communication conforming to the HDMI standard. The HDMI terminal  110  is an example of an output interface in the digital camera  10  of the present embodiment. 
     The SDI terminal  112  is a connection terminal for outputting a digital signal to the connected external apparatus in conformity with the SDI standard. A display apparatus such as a monitor  32  different from the external monitor  30  connected to the HDMI terminal  110  is connected to the SDI terminal  112 , for example. A plurality of monitors may be connected to the digital camera  10  according to various uses. 
     The USB terminal  114  is a connection terminal that performs data communication between the connected external apparatus and the digital camera  10  in conformity with the USB standard. For example, an information terminal  34  functioning as a display apparatus of a personal computer (PC), a smartphone, or the like is connected to the USB terminal  114 . Each of the terminals  112  and  114  is an example of a communication interface in the digital camera  10 . The information terminal  34  may transmit various control signals to the digital camera  10 . Hereinafter, the communication connection between the digital camera  10  and the information terminal  34  may be referred to as a Tether connection. 
     The output interface and the communication interface of the digital camera  10  are not particularly limited to the above. For example, the digital camera  10  may be provided with an interface circuit that performs data communication in conformity with a communication standard corresponding to the various terminals  110  to  114 , and the output interface or the communication interface may include such an interface circuit. In addition, the communication standards are not limited to the above communication standards, and various wired or wireless communication standards may be adopted. 
     1-2. User Interface 
     A specific example of the user interface  150  in the digital camera  10  will be described with reference to  FIG.  3   .  FIG.  3    is a diagram illustrating a user interface  150  and a setting menu of the digital camera  10 . 
       FIG.  3    shows a shooting button  151 , a selection button  154 , and a plurality of function buttons (Fn buttons)  156  and  158  as an example of the user interface  150  provided on the side surface of the digital camera  10 . When receiving an operation by the user, the user interface  150  transmits various instruction signals to the controller  180 . 
     For example, the shooting button  151  is a depression type button for starting/ending shooting recording of a moving image. The controller  180  controls recording of a moving image data in the memory card  200  or the like in response to the depressing operation of the shooting button  151 , for example. 
     The selection button  154  includes a depression type buttons provided in the up, down, left, and right directions and a depression type MENU/SET button  155  provided at the center. For example, when the user depresses the MENU/SET button  155  with the digital camera  10  being in a predetermined operation mode, the controller  180  causes the external monitor  30  to display a setting menu. 
       FIG.  3    illustrates a state in which a setting menu screen is displayed on the external monitor  30  connected to the digital camera  10 . The setting menu is an example of setting information for setting various operations such as shooting in the digital camera  10 . 
     The user can select various menu items or options displayed on the screen of the setting menu or move the cursor by depressing any one of the selection buttons  154  of the up, down, left, and right directions. When the MENU/SET button  155  is depressed in a state where a specific menu item is selected in the setting menu, the controller  180  causes the external monitor  30  to display an option of changing the setting of the selected menu item. Furthermore, when the MENU/SET button  155  is depressed in a state where a specific option is selected, the controller  180  establishes the setting of the selected menu item reflecting the option. 
     Each of the Fn buttons  156  and  158  is a depression type button to which a specific function in the digital camera  10  can be assigned by, for example, a user operation in a setting menu. In the present embodiment, a case where a function of turning ON/OFF the RAW output setting described below is assigned to the Fn button  156  will be described. 
     2. Operation 
     The operation of the digital camera  10  configured as described above will be described in the following. 
     2-1. Outline of Operation 
     The digital camera  10  of the present embodiment has a RAW output setting that is a setting for outputting RAW data such as a moving image to the external monitor  30  connected to the HDMI terminal  110 , for example. When the RAW output setting is applied, a moving image of RAW data during shooting in the digital camera  10  can be displayed or recorded on the external monitor  30 . 
     For example, as shown in  FIG.  3   , the setting menu of the digital camera  10  includes a menu item for allowing the user to select ON/OFF of whether or not to apply the RAW output setting. In this case, the user can cause the external monitor  30  to display a setting menu from a state in which the RAW output setting of the digital camera  10  is OFF, and turn ON the RAW output setting from the setting menu displayed on the external monitor  30 . 
     With regard to the ON/OFF of the RAW output setting as described above, the inventors of the present application have revealed the following problems through energetic research. 
     That is, in a state where the RAW output setting is turned ON, the setting menu cannot be displayed on the external monitor  30  as the output destination of the RAW data. This is because OSD information such as a setting menu cannot be superimposed on the output RAW data. In order for the user to use the setting menu in this state, it is conceivable to additionally prepare a display apparatus (e.g., the monitor  32  or the information terminal  34 ) different from the external monitor  30  as an output destination of the RAW data and connect the display apparatus to the digital camera  10 . However, when the additional display apparatus as described above is not prepared, it is conceivable to have a situation in which the RAW output setting cannot be returned to OFF temporarily the user turns ON the RAW output setting. 
     Thus, in the digital camera  10  in the present embodiment, an input interface that responds to a user&#39;s instruction regarding RAW output setting is provided separately from the setting menu. Accordingly, in the digital camera  10  of the present embodiment, the RAW output setting can be returned to OFF by the input interface when the user desires even without using the display of the setting menu in the state where the RAW output setting is ON. Hereinafter, the operation of the digital camera  10  will be described in detail. 
     2-2. Details of Operation 
     In the digital camera  10  of the present embodiment, the Fn button  156 , to which the ON/OFF function of the RAW output setting is assigned, is an example of the above-described input interface. The operation of the digital camera  10  when the assignment is performed in advance will be described with reference to  FIGS.  4  to  5   . 
       FIG.  4    is a flowchart illustrating an operation of RAW output setting in the digital camera  10 . The processing shown in the flow in  FIG.  4    is started in a state where the RAW output setting of the digital camera  10  is OFF, and is executed by the controller  180 . Hereinafter, a case where the external monitor  30  is connected to the HDMI terminal  110  and the other display apparatuses  32  and  34  are not connected to the digital camera  10  will be described. 
     First, the controller  180  detects an input of a user operation for switching the RAW output setting from OFF to ON in the digital camera  10  (S 1 ). For example, the user operation to be detected in step S 1  may be an operation of depressing the Fn button  156  or an operation of RAW output setting in a setting menu. 
     When the ON operation of the RAW output setting is not input (NO in S 1 ), the controller  180  does not particularly output the RAW data of the imaging result of the image sensor  140  to the external monitor  30  even when the RAW data is generated, and repeats the detection in step S 1 . At this time, various information other than RAW data may be output from the digital camera  10  to the external monitor  30  via the HDMI terminal  110 . For example, image data obtained by performing development processing on RAW data, or data for displaying setting information such as a setting menu may be output as an image signal. On this occasion, in the digital camera  10 , the development processing described above, processing of superimposing a setting menu on a developed image, or the like are performed. 
     When the ON operation of the RAW output setting is input (YES in S 1 ), the controller  180  causes the external monitor  30  to display a screen of a predetermined caution message by data communication via the HDMI terminal  110 , for example (S 2 ). A display example in step S 2  will be described with reference to  FIG.  5   . 
       FIG.  5    shows a display example of a caution message screen displayed on the external monitor  30  connected to the digital camera  10 . In the present example, the caution message screen is displayed as a pop-up or the like on the external monitor  30  under the control (S 2 ) of the controller  180 , and includes a caution message  50  and YES/NO options  51  and  52 . 
     The caution message  50  includes three notification contents as shown in  FIG.  5   , for example. The first notification contents are a warning of notifying the user beforehand that the setting menu is not displayed on the external monitor  30  connected to the HDMI terminal  110  in the ON state of the RAW output setting. The second notification contents are a proposal for urging the user to separately prepare a display apparatus for displaying the setting menu by the SDI terminal  112  or the Tether connection. The third notification contents are confirmation for causing the user to select whether or not to change the RAW output setting from OFF to ON. 
     For example, in a state where the caution message screen shown in  FIG.  5    is displayed on the external monitor  30 , the controller  180  receives a user operation of selecting any one of the YES/NO options  51  and  52  using the selection button  154  or the like (S 3 ). 
     For example, when the option  52  of “NO” is selected by the user operation and the option  51  of “YES” is not selected (NO in S 3 ), the controller  180  controls the external monitor  30  so that the external monitor  30  deletes the caution message screen displayed from the HDMI terminal  110 , and returns to the processing in step S 1 . 
     On the other hand, when the option  51  of “YES” is selected by the user operation (YES in S 3 ), the controller  180  turns ON (i.e., applies) the RAW output setting to the digital camera  10  (S 4 ). For example, the controller  180  performs various setting changes for enabling the digital camera  10  to output RAW data of a moving image from the HDMI terminal  110  to the external monitor  30 . On this occasion, when a display apparatus different from the external monitor  30  is not particularly connected to the digital camera  10 , the controller  180  may set the user operation for displaying the setting menu as disabled. 
     The controller  180  outputs the moving image RAW data generated in the digital camera  10  to the external monitor  30  via the HDMI terminal  110  (S 5 ). For example, in the digital camera  10 , the image sensor  140  performs an imaging operation and sequentially generates RAW data indicating an imaging result. The controller  180  outputs RAW data for each frame at a predetermined frame rate to the external monitor  30  as moving image RAW data, for example. The moving image RAW data may be generated by appropriately performing processing different from the development processing on the imaging result of the image sensor  140  in the image processor  160 , for example. 
     In the ON state of the RAW output setting, the controller  180  detects an input of a user operation of depressing the Fn button  156  at any time (S 6 ). The detection target in step S 6  is a user operation for switching the RAW output setting from ON to OFF (i.e., canceling the RAW output setting). 
     When the depressing operation on the Fn button  156  is not input in the ON state of the RAW output setting (NO in S 6 ), the controller  180  continues to output the moving image RAW data from the HDMI terminal  110  to the external monitor  30  (S 5 ). 
     On the other hand, when the depressing operation on the Fn button  156  is input in the ON state of the RAW output setting (YES in S 6 ), the controller  180  turns OFF (i.e., cancels) the RAW output setting in the digital camera  10  (S 7 ). For example, in step S 7 , the controller  180  stops outputting of the moving image RAW data from the HDMI terminal  110  to the external monitor  30 . The controller  180  may output, to the external monitor  30 , an image signal indicating the developed image data in YC format or the like instead of RAW format. 
     The controller  180  controls the digital camera  10  to be in the OFF state of the RAW output setting (S 7 ), and ends the processing shown in the present flow. 
     According to the above processing, even when the menu is not displayed on the external monitor  30  with the moving image RAW data being output from the HDMI terminal  110  in the digital camera  10  to the external monitor  30 , the RAW output setting can be turned OFF at any time by the depressing operation on the Fn button  156  (S 5  to S 7 ). The cancellation of the RAW output setting can be performed even in a state where a display apparatus different from the external monitor  30  cannot be prepared and a menu cannot be displayed in particular. Thus, and this can facilitate the user to use the RAW output settings. 
     In the above description, as illustrated in  FIG.  5    in step S 2 , an example in which three notification contents are included in the caution message  50  has been described. The caution message  50  displayed in step S 2  is not particularly limited to the example in  FIG.  5   , and may include any one or two notification contents without including all of the three notification contents, for example. 
     2-2-1. Forced OFF Processing 
     In the digital camera  10 , a case is assumed where the ON/OFF function of the RAW output setting described above is not assigned to the Fn button  156  due to user setting or the like. The digital camera  10  of the present embodiment receives an instruction to forcibly turn OFF the RAW output setting even in such a case. The forced OFF processing will be described with reference to  FIG.  6   . 
       FIG.  6    is a flowchart for illustrating forced OFF processing of the digital camera  10 . The processing shown in the flowchart in  FIG.  6    is executed by the controller  180  in parallel with the processing illustrated in  FIG.  4    in a state where the RAW output setting is ON, for example. 
     First, the controller  180  detects whether or not a predetermined reset operation is input in the digital camera  10  (S 21 ). The reset operation is a user operation preset to forcibly return the operation setting related to information output or the like of the digital camera  10  to an initial state or the like. For example, the reset operation is a multiplex pressing operation of simultaneously depressing a plurality of buttons  155 ,  156 , and  158  of a specific combination. 
     When the reset operation is not input (NO in S 21 ), the controller  180  does not particularly change the setting of the digital camera  10 , and repeats the detection in step S 21 . For example, when the RAW output setting is in the ON state, outputting of the moving image RAW data is continued. 
     When the reset operation is input (YES in S 21 ), the controller  180  switches the RAW output setting of the digital camera  10  from ON to OFF (S 22 ). The processing in step S 22  is performed similarly to step S 7  in  FIG.  4   . 
     In addition, the controller  180  resets a setting different from the RAW output setting regarding the information output from the digital camera  10 , for example (S 23 ). For example, the digital camera  10  has an information display setting being a setting for preselecting an apparatus caused to display information such as a setting menu (see  FIG.  3   ). In step S 23 , the controller  180  forcibly changes the information display setting to “AUTO” being the initial setting, for example. 
     The “AUTO” of the information display setting is a setting state in which a target for displaying setting information such as a setting menu is automatically selected from connection destinations of the HDMI terminal  110  and the SDI terminal  112 , for example. For example, in addition to “AUTO”, the information display setting has setting states such as “HDMI” for fixing an apparatus to be displayed to a connection destination of the HDMI terminal  110 , “SDI” for fixing an apparatus to be displayed to a connection destination of the SDI terminal  112 , and “OFF” for not displaying information to any connection destination. 
     When resetting the setting for the information output of the digital camera  10  (S 23 ), the controller  180  ends the processing shown in the present flow. 
     According to the forced OFF processing of the digital camera  10  described above, for example, even in an emergency situation where the RAW output setting is turned ON with the ON/OFF function of the RAW output setting not assigned to the Fn button  156 , the RAW output setting can be forcibly turned OFF (S 21  to S 22 ). 
     In addition, resetting the information display setting together with the RAW output setting (S 23 ) allows a setting menu to be displayed on the connection destination of the digital camera  10 , such as the external monitor  30 , after the reset operation, for example. As described above, it is possible for the user to collectively handle, by the reset operation, the emergency situation in which the setting menu or the like cannot be displayed. Thus, it is possible for the user to easily use the settings of various outputs of the digital camera  10 . 
     3. Effects and the Like 
     As described above, the digital camera  10  according to the present embodiment is an example of a digital camera  10  that does not include a display that displays a setting menu (see  FIG.  3   ) being an example of setting information for operation setting in the own apparatus. The digital camera  10  includes an image sensor  140  being an example of an image sensor, an HDMI terminal  110  being an example of an output interface, and a controller  180 . The image sensor  140  captures a subject image to generate image data. The HDMI terminal  110  is connected to an external monitor  30  being an example of an external apparatus, to output image data. The controller  180  controls a RAW output setting being an example of an output setting for outputting image data in a RAW format being an example of a predetermined format, that is, RAW data from the HDMI terminal  110  to the external monitor  30 . In a state where the RAW output setting is applied (ON), the setting menu for canceling the RAW output setting is not displayed on the external monitor  30  being the output destination of the RAW data by the HDMI terminal  110 . The digital camera  10  further includes a user interface  150  such as an Fn button  156  as an example of an input interface that receives an instruction to cancel (OFF) the RAW output setting from the state where the RAW output setting is applied. 
     According to the above digital camera  10 , even when the setting menu is not displayed on the external monitor  30  in a state where the RAW output setting is turned ON, the input interface that responds to the instruction to cancel the RAW output setting can avoid a situation where the RAW output setting cannot be returned to OFF. Accordingly, in the digital camera  10  in which the setting menu and the like are not displayed, it is possible to suppress a situation in which it is difficult to use the RAW output setting, and possible to facilitate use of the setting of outputting data to the external apparatus. 
     In the digital camera  10  of the present embodiment, in a state where the RAW output setting is applied (S 4  to S 6 , S 21 ), the input interface responds to the instruction to cancel the RAW output setting without causing the external display apparatuses  32  and  34  to display a setting menu for canceling the RAW output setting (S 7 , S 22 ). Accordingly, the user can return the RAW output setting of the digital camera  10  to OFF without particularly preparing the additional display apparatuses  32  and  34  in addition to the external monitor  30  being the output destination of the moving image RAW data, and the RAW output setting can be easily used. 
     In the digital camera  10  of the present embodiment, when an instruction to apply the RAW output setting is input in a state where the RAW output setting is not applied (YES in S 1 ), the controller  180  causes the external monitor  30  being an output destination to display a predetermined message such as a caution message  50  (S 2 ). The predetermined message includes at least one of a notification of giving an advance notice that the setting menu is not displayed on the external monitor  30  being the output destination when the RAW output setting is applied, a notification of urging preparation of display apparatuses  32  and  34  different from the external monitor  30  being the output destination, or a notification of confirming whether or not to apply the RAW output setting (see  FIG.  5   ). The notification allows the user to easily use the RAW output setting. 
     The digital camera  10  of the present embodiment further includes a user interface  150  that receives a user operation according to a setting menu displayed on the external monitor  30  in a state where the RAW output setting is not applied. That is, the external monitor  30  can display a setting menu in a state where the RAW output setting is not applied. When the RAW output setting is OFF, the user can display a setting menu on the external monitor  30  to use various settings. 
     In the digital camera  10  of the present embodiment, the input interface includes an Fn button  156  as an example of an operation member to which a function of switching whether or not to apply the RAW output setting is assigned, in the operation member in the user interface  150  provided in the digital camera  10 . An instruction to cancel the RAW output setting when the RAW output setting is ON can be input using the Fn button  156  to which the above function is assigned (S 6 ). 
     In the digital camera  10  of the present embodiment, the user interface  150  being an example of the input interface receives an instruction to cancel the output setting according to a predetermined user operation such as a preset reset operation regardless of whether or not the switching function is assigned to the Fn button  156  (S 21 ). Accordingly, even when the RAW output setting is turned ON with the function described above not assigned to the Fn button  156 , the RAW output setting can be forcibly returned to OFF. 
     In the digital camera  10  of the present embodiment, the predetermined format is a RAW format corresponding to a state where the image sensor  140  has performed imaging. The target image data output from the output interface in the RAW output setting is, for example, moving image RAW data. The image data being an output target is not necessarily limited to moving image RAW data, and may be still image RAW data, for example. The predetermined format may be a format incapable of superposing OSD or GUI (e.g. caption or setting information) with the data such as RAW data. 
     In the digital camera  10  of the present embodiment, the HDMI terminal  110  being an example of an output interface outputs image data to the external monitor  30  in conformity with the HDMI standard. The communication standard by the output interface is not necessarily limited to the HDMI standard, and may be various communication standards in which predetermined format image data such as RAW data can be output. 
     Other Embodiments 
     As described above, the first embodiment has been described as an exemplification of the technique disclosed in the present application. However, the technique in the present disclosure is not limited thereto, and can also be applied to embodiments in which changes, substitutions, additions, omissions, and the like are made as appropriate. In addition, it is also possible to combine each component described in the above embodiment to form a new embodiment. Thus, in the following, other embodiments will be exemplified. 
     In the first embodiment described above, an operation example when only the external monitor  30  being the output destination of the moving image RAW data is connected to the digital camera  10  has been described. In the present embodiment, in addition to the external monitor  30 , a display apparatus such as the monitor  32  or the information terminal  34  may be connected to the digital camera  10 . For example, with the moving image RAW data being output from the HDMI terminal  110  to the external monitor  30  in the digital camera  10 , the setting menu of the digital camera  10  may be separately displayed on the display apparatuses  32  and  34  connected to the various terminals  112  and  114 . In this case, a user operation for checking or changing various settings such as video quality of moving image RAW data in the digital camera  10  can be input using the displayed setting menu. In addition, a user operation of turning OFF the moving image RAW setting may be input. 
     As described above, the digital camera  10  of the present embodiment further includes the various connection terminals  112  and  114  as an example of a communication interface different from the output interface, and the user interface  150 . The communication interface is connected to the external display apparatuses  32  and  34  separately from the output destination of the output interface to perform data communication, and the user interface  150  receives a user operation corresponding to the setting menu displayed on the display apparatus in a state where the RAW output setting is applied and the setting menu is not displayed on the external monitor  30  being the output destination. 
     Accordingly, for example, by using the various display apparatuses  32  and  24  with a combined use of the external monitor  30  that is the output destination of the moving image RAW data, the user can easily use the digital camera  10  such as being able to use the setting menu. For example, an instruction to turn OFF the moving image RAW setting from the setting menu may be input by a user operation of the user interface  150  according to the setting menu, or may be input to the digital camera  10  via the connection terminal  114  from an operation of the information terminal  34  or the like. 
     In the above embodiments, the example in which the ON/OFF function of the RAW output setting is assigned to the Fn button  156  has been described. To the Fn button  156 , the function of turning ON the RAW output setting does not need to be assigned, and only the function of turning OFF the RAW output setting may be assigned. When the digital camera  10  is in an operation state where ON/OFF of the RAW output setting cannot be executed even with various display apparatuses used, the operation of the above Fn button  156  may be disabled. 
     In the above embodiments, the Fn button  156  has been exemplified as an example of the input interface in the digital camera  10 . In the present embodiment, the input interface is not limited to the Fn button  156 , and may be various user interfaces  150  in the digital camera  10 . The input interface is not limited to the user interface  150 , and may be configured to receive an instruction to cancel RAW output setting by voice input, for example. Alternatively, an interface circuit connected to a remote control unit or the like to which such a cancelation instruction can be input may be used. 
     In the above embodiments, the setting menu has been exemplified as an example of the setting information in the digital camera  10 . In the digital camera  10  of the present embodiment, the setting information is not limited to the setting menu, and may be various information that can be operated and set in the digital camera  10 , or may be various on-screen display (OSD) information. 
     In the above embodiments, the external monitor  30  has been described as an example of the external apparatus being the output destination of the output interface. In the present embodiment, the external apparatus is not particularly limited to the external monitor  30 , and may be an information terminal such as a PC or an external recorder, for example. 
     In the above embodiments, an example of the configuration of the digital camera  10  has been described as an example of the imaging apparatus. In the present embodiment, the digital camera  10  is not particularly limited to the above configuration, and may have various configurations. For example, the digital camera  10  does not need to be an interchangeable lens type, and may be an integrated lens type. In addition, the digital camera  10  does not need to be particularly a box camera.
