[0038] Hereinafter, preferred embodiments of the imaging device, imaging method, and program according to the present invention will be described with reference to the accompanying drawings.

[0039] Figure 1 This is a diagram conceptually showing an external recorder connected to an imaging device.

[0040] The camera device (digital camera) 1 is connected to an external recorder 3 via an HDMI (registered trademark) (High-Definition Multimedia Interface) cable 5. The camera device 1 shoots animation (dynamic image data) and still images according to instructions from an operating unit such as a shutter button. In addition, in a shooting preparation state, a live preview image serving as display data is displayed on a rear display (not shown) provided on the rear side of the camera device 1 and / or a viewfinder (not shown) of the camera device 1. The camera device 1 has a connector 109 ( Figure 2 ), is connected to the external recorder 3 via the HDMI cable 5. The imaging device 1 outputs the captured moving image data to the external recorder 3 via the HDMI cable 5.

[0041] The external recorder 3 is an example of an external device that can be connected to the imaging device 1. Another example of an external device is an external display. The external recorder 3 has a connection unit 203 ( Figure 2), is connected to the camera 1 via an HDMI cable 5. The external recorder 3 obtains the dynamic image data shot by the camera 1 via the HDMI cable 5, and records it in the recording unit 209. Furthermore, the external recorder 3 obtains the dynamic image data shot by the camera 1 via the HDMI cable 5, and displays it on the display unit 207. In addition, in this example, an example of connecting the camera 1 and the external recorder 3 via the HDMI cable 5 is described, but the present invention is not limited to this example. For example, the camera 1 and the external recorder 3 can be connected via a USB (Universal Serial Bus) cable, or can be connected wirelessly via Wi-Fi or the like as described later.

[0042] Here, the types (specifications) and settings of dynamic image data processing are explained. There are many types and settings of dynamic image data processing. For example, there are BT.709 and BT.2100 recommended by ITU-R (International Telecommunication Union-Radiocommunication Sector) or Log animation and animation RAW specified by each camera manufacturer. Therefore, in order to display the dynamic image data captured by the camera device 1 on the display unit (display) 207 of the external recorder 3 with accurate color and brightness, it is sometimes necessary to change the display quality setting of the external recorder 3 according to the animation quality setting of the camera device 1. In addition, "animation quality setting" and "display quality setting" are at least one of color gamut, gamma, video range, lookup table (LookUpTable), and brightness settings.

[0043] However, the video quality setting of the camera 1 and the display quality setting of the external recorder 3 may sometimes be inconsistent. For example, the video quality setting of the camera 1 may be BT.2100, while the display quality setting of the external recorder 3 may be BT.709. In this case, the gamma and color gamut processing differ significantly between BT.2100 and BT.709. Consequently, the live preview image displayed on the external recorder 3 processed in BT.709 has a darker exposure and lower saturation than the video data from the camera 1 processed in BT.2100. It is conceivable that the user, after viewing the live preview image displayed on the display unit 207 of the external recorder 3, may change the video quality setting of the camera 1 and shoot. Specifically, they may shoot with a video quality setting that increases saturation or exposure. Consequently, the video data generated by the camera 1 using the BT.2100 setting may have excessively high saturation or exposure.

[0044] Therefore, the user needs to confirm whether the image quality setting of the display unit 207 of the external recorder 3 is accurately set relative to the image quality setting of the video camera 1. Therefore, in this embodiment, it is possible to easily and visually determine whether the display image quality of the display unit 207 of the external recorder 3 is accurately set relative to the image quality setting of the video camera 1.

[0045] Figure 2 This is a block diagram showing main functions of the imaging device 1 and the external recorder 3 .

[0046] The imaging device 1 mainly includes a lens 103, an imaging element 105, a CPU (Central Processing Unit) 107, a display unit 113, a memory 111, and a connection unit 109. The external recorder 3 mainly includes a connection unit 203, a CPU 205, a display unit 207, and a recording unit 209.

[0047] The lens 103 forms a subject image (optical image) on the imaging element 105. Although not shown, the lens 103 includes a control mechanism such as an aperture, and the imaging device 1 also includes a shutter for controlling the formation of the subject image on the imaging element 105.

[0048] The imaging element 105 has a light-receiving surface formed by a plurality of light-receiving elements arranged in a matrix. Each light-receiving element receives light corresponding to the image of the subject formed on the light-receiving surface of the imaging element 105 and converts it into an electrical signal. R (red), G (green), and B (blue) color filters are provided on the light-receiving surface of the imaging element 105, so that a color image of the subject can be obtained based on the signals of each color. In addition, various imaging elements such as CMOS (Complementary Metal-Oxide Semiconductor) and CCD (Charge-Coupled Device) can be used as the imaging element 105. The imaging element 105 performs noise removal and amplification on the analog image signal via an internal AFE (Analog Front End) (not shown), and similarly converts the analog image signal into a digital image signal having a grayscale width via an internal A / D converter (Analog / Digital Converter) (not shown). The AFE and A / D converter can also be connected externally. The moving image data captured by the imaging device 1 is composed of data including a plurality of frames, and each frame is generated as a digital image signal as described above.

[0049] The digital image signal (a signal composed of frames constituting the moving image data) is processed by CPU 107. CPU 107 performs image processing on the digital image signal, such as color signal separation, white balance adjustment, and gamma correction. CPU 107 performs various image processing operations on the digital image signal according to the type and settings of the animation. The image processing performed by CPU 107 will be described later.

[0050] The CPU 107 also controls the entire imaging device 1. The CPU 107 reads necessary programs and information used for various controls from the memory 111 and performs various processing and controls. The memory 111 is the internal memory of the imaging device 1 and stores programs required for various imaging operations of the imaging device 1. Furthermore, the CPU 107 controls the display of the display unit 113. Specific examples of the display unit 113 include the rear display and electronic viewfinder of the imaging device 1.

[0051] The connection unit 109 of the camera 1 and the connection unit 203 of the external recorder 3 are connected via an HDMI cable 5. Dynamic image data is input from the camera 1 to the connection unit 203 of the external recorder 3. The external recorder 3 records the input dynamic image data in the recording unit 209. Furthermore, the CPU 205 displays the input dynamic image data on the display unit 207. Here, the display unit 207 is connected from the connection unit via the CPU 205, but the display unit 207 and the connection unit 203 may also be connected, for example, the display unit is controlled by the CPU 205. In addition, the CPU 205 performs overall control including the aforementioned recording control of the external recorder 3 to the recording unit 209. The CPU 205 reads necessary programs and information used for various controls from the memory (not shown) of the external recorder 3, and performs various processes and various controls by the CPU 205.

[0052] The hardware configuration of CPU 107 and CPU 205 is composed of various processors as shown below. These processors include general-purpose processors (CPUs) that execute software (programs) to function as various functional units; processors (e.g., programmable logic devices (PLDs)) whose circuit configuration can be modified after manufacturing, such as FPGAs (Field Programmable Gate Arrays); and processors (e.g., dedicated circuits) with circuit configurations specifically designed to execute specific processing, such as ASICs (Application Specific Integrated Circuits).

[0053] One functional unit may be composed of one of these various processors, or may be composed of two or more processors of the same or different types (for example, multiple FPGAs, or a combination of a CPU and an FPGA). In addition, multiple functional units may be composed of one processor. As an example of a method in which multiple functional units are composed of one processor, there is a method in which a processor is composed of a combination of one or more CPUs and software, such as a computer for a client or server, and the processor functions as multiple functional units. Second, there is a method in which a processor that realizes the functions of the entire system including multiple functional units through one IC (Integrated Circuit) chip is used, such as a system-on-chip (SoC). In this way, various functional units are composed of one or more of the above-mentioned various processors as a hardware structure.

[0054] Figure 3 This is a block diagram showing the moving image data processing function implemented by the CPU 107 .

[0055] The CPU 107 includes a first moving image data processing unit 121 , a second moving image data processing unit 123 , and a third moving image data processing unit 125 .

[0056] The first moving image data processing unit 121 processes the moving image data (RAW) according to the moving image quality setting (first setting condition). Here, the moving image data (RAW) is moving image data that has not yet undergone image processing and is data containing information about the subject image captured by the imaging element 105 as is. The moving image quality setting is a condition set in the imaging device 1, and the recorded moving image data and live preview images use the first moving image data processed according to the moving image quality setting. For example, the moving image quality setting is HLG (Hybrid Log Gamma) and PQ (Perceptual Quantization) of BT.2100.

[0057] The second moving image data processing unit 123 processes the moving image data (RAW) according to the display image quality setting (second setting condition). The display image quality setting is a condition set in the external recorder 3. The second moving image data processed according to the display image quality setting is displayed on the display unit 207 of the external recorder 3. For example, if the display image quality setting of the display unit 207 of the external recorder 3 is BT.709, the second moving image data processing unit 123 processes the moving image data (RAW) according to BT.709.

[0058] The third moving image data processing unit 125 generates third moving image data representing the difference between the video quality setting and the display quality setting based on the first and second moving image data. By viewing the third moving image data, the user can easily visually discern the difference between the video quality setting and the display quality setting.

[0059] For example, if the image quality setting of the video camera 1 differs from the image quality setting of the display unit 207 of the external recorder 3, the first and second moving image data will have different image qualities. Therefore, the user can easily visually discern the different image qualities by observing the third moving image data displayed on the display unit 207. On the other hand, if the image quality setting of the video camera 1 matches the image quality setting of the display unit 207 of the external recorder 3, the first and second moving image data will have the same image quality. Therefore, the user can easily visually discern the same image quality by observing the third moving image data displayed on the display unit 207.

[0060] Figure 4 This is a schematic diagram showing an example of third dynamic image data. The third dynamic image data V3(1) generates a plurality of first frames VF1 constituting the first dynamic image data V1 and a plurality of second frames VF2 constituting the second dynamic image data V2 by alternately arranging them in chronological order. In the third dynamic image data V3(1), the first frames VF1 and the second frames VF2 are arranged every five frames in chronological order. Furthermore, the first frames VF1 are processed using the animation quality setting, while the second frames VF2 are processed using the display quality setting.

[0061] When the animation image quality setting and the display image quality setting are different, the image quality of the first frame VF1 and the second frame VF2 are different. In this case, if the third dynamic image data V3(1) is displayed on the display unit 207, the first frame VF1 and the second frame VF2, each having a different image quality, are repeatedly displayed at a predetermined interval. Therefore, the image quality of the displayed third dynamic image data V3(1) changes repeatedly, so that the user can easily visually distinguish that the animation image quality setting and the display image quality setting are different. On the other hand, when the animation image quality setting and the display image quality setting are the same, the image quality of the first frame VF1 and the second frame VF2 are the same. Therefore, the image quality of the third dynamic image data V3(1) is stably displayed without changing, so that the user can easily visually distinguish that the animation image quality setting and the display image quality setting are the same.

[0062] In the third dynamic image data V3(1), as shown in the figure, a plurality of first frames VF1 and a plurality of second frames VF2 are alternately arranged along a time series. For example, the first dynamic image data (a plurality of first frames VF1) and the second dynamic image data (a plurality of second frames VF2) may be alternately arranged every second in the third dynamic image data V3(1). Alternatively, the first frame VF1 and the second frame VF2 may be alternately arranged on a single frame basis to form the third dynamic image data V3(1).

[0063] Figure 5 This is a flowchart illustrating an imaging method (and a program for executing the imaging method) using the imaging device 1 to which the external recorder 3 is connected.

[0064] First, the first moving image data processing unit 121 of the camera 1 obtains the video quality setting "MV_SET" of the camera 1 (step S101). Next, the monitor quality setting "MON_SET" of the external recorder 3 is transmitted from the external recorder 3 (CPU 205) to the camera 1 via the HDMI cable 5, and the second moving image data processing unit 123 of the camera 1 obtains the monitor quality setting "MON_SET" (step S102).

[0065] Next, the CPU 107 obtains the dynamic image data (RAW) from the imaging element 105 (step S103). Specifically, the frames constituting the dynamic image data (RAW) are obtained in the order of the frame numbers along the time series. Thereafter, the CPU 107 determines whether a recording start instruction signal is received and performs animation recording (step S104). If the CPU 107 determines that animation recording is in progress, the first dynamic image data processing unit 121 of the imaging device 1 generates the first dynamic image data corresponding to "MV_SET" and sends the first dynamic image data to the external recorder 3 (step S105). On the other hand, if the CPU 107 determines that animation recording is not in progress, the third dynamic image data processing unit 125 determines whether the number calculated according to the following formula is an even number (step S111).

[0066] Formula: Int(Frame / n)

[0067] Here, Int(α) in the formula represents the decimal value of the number α in the brackets, Flame represents the frame number of the moving image data (RAW), and n represents the frame cycle of the process switching. The frame cycle n of the process switching can be arbitrarily determined by the user.

[0068] Then, if CPU 107 determines that the number calculated according to the equation is an even number, first moving image data processing unit 121 generates first moving image data corresponding to "MV_SET" and sends it to third moving image data processing unit 125 (step S112). On the other hand, if CPU 107 determines that the number calculated according to the equation is not an even number, second moving image data processing unit 123 generates second moving image data corresponding to "MON_SET" and sends it to third moving image data processing unit 125 (step S113). Third moving image data processing unit 125 then generates third moving image data based on the generated first and second moving image data, and sends the third moving image data to external recorder 3 (step S114). Thus, in this embodiment, the first and second moving image data are switched based on the number Flame (frame number) / n (frame period for switching between processes), and then the third moving image data is generated. This makes it possible to efficiently perform the process of generating the first moving image data and the process of generating the second moving image data with respect to the moving image data (RAW).

[0069] Thereafter, the CPU 107 determines whether the video quality setting of the imaging device 1 has been updated (step S106 ). If the video quality setting of the imaging device 1 has been updated, the CPU 107 updates “MV_SET” of the imaging device 1 (step S107 ).

[0070] Next, CPU 107 determines whether the display image quality setting of external recorder 3 has been updated (step S108). The updated "MON_SET" is then transmitted from external recorder 3 to imaging device 1 (step S109). CPU 107 then determines whether animation mode has ended (step S110). If animation mode has not ended, the process returns to step S103 to process the next frame of moving image data (RAW).

[0071] As described above, in this embodiment, third moving image data in which a plurality of first frames VF1 and a plurality of second frames VF2 are alternately arranged is generated by the third moving image data processing unit 125. The user can then easily visually determine whether the animation image quality setting and the display image quality setting have been correctly set by observing the third moving image data displayed on the display unit 207 of the external recorder 3.

[0072] The above-described structures and functions can be implemented as appropriate using any hardware, software, or a combination of both. Furthermore, the CPU 107 can also perform dynamic image data processing instead of the dynamic image data processing units. For example, the present invention can be applied to a program that causes a computer to execute the above-described processing steps (processing flow), a computer-readable recording medium (non-transitory recording medium) storing such a program, or a computer capable of installing such a program.

[0073] <Modification of the first embodiment>

[0074] Next, a modification of the first embodiment will be described. In the first embodiment, for frames constituting the dynamic image data (RAW), first dynamic image data or second dynamic image data (see FIG. 1 ) is generated based on its frame number. Figure 5 In this example, the first moving image data and the second moving image data are simultaneously generated for the frames constituting the moving image data (RAW).

[0075] Figure 6 This is a flowchart illustrating an imaging method (and a program for executing the imaging method) using the imaging device 1 to which the external recorder 3 is connected.

[0076] First, the first moving image data processing unit 121 of the camera 1 obtains the video quality setting "MV_SET" of the camera 1 (step S201). Next, the monitor quality setting "MON_SET" of the external recorder 3 is transmitted from the external recorder 3 (CPU 205) to the camera 1 via the HDMI cable 5, and the second moving image data processing unit 123 of the camera 1 obtains the monitor quality setting "MON_SET" (step S202).

[0077] Next, the CPU 107 acquires moving image data (RAW) from the imaging element 105 (step S203). The first moving image data processing unit 121 then generates first moving image data for "MV_SET" (step S204). Furthermore, the second moving image data processing unit 123 generates second moving image data for "MON_SET" (step S205).

[0078] After that, the CPU 107 determines whether a recording start instruction signal is received and performs animation recording (step S206). If the CPU 107 determines that animation recording is in progress, the first dynamic image data processing unit 121 generates the first dynamic image data corresponding to "MV_SET" and sends it to the external recorder 3 (step S207). On the other hand, if the CPU 107 determines that animation recording is not in progress, the third dynamic image data processing unit 125 performs the processing according to the above formula (reference Figure 5In step S111), it is determined whether the calculated number is an even number (step S213).

[0079] Then, if CPU 107 determines that the number calculated according to the equation is an even number, the first moving image data processing unit 121 of the camera 1 sends the first moving image data corresponding to "MV_SET" to the third moving image data processing unit 125 (step S214). On the other hand, if CPU 107 determines that the number calculated according to the equation is not an even number, the second moving image data processing unit 123 of the camera 1 sends the second moving image data corresponding to "MON_SET" to the third moving image data processing unit 125 (step S215). The third moving image data processing unit 125 then generates third moving image data based on the generated first and second moving image data, and sends it to the external recorder 3 (step S216). Thus, in this example, the first and second moving image data are simultaneously generated for the frames constituting the moving image data (RAW). Consequently, all frames constituting the moving image data (RAW) contain the first and second moving image data.

[0080] In addition, the following steps S208 to S212 are Figure 5 Steps S106 to S110 described in are corresponding, so their description is omitted.

[0081] As described above, in this example, the third moving image data processing unit 125 generates third moving image data in which a plurality of first frames VF1 constituting the first moving image data V1 and a plurality of second frames VF2 constituting the second moving image data V2 are alternately arranged. The third moving image data is then displayed on the display unit 207 of the external recorder 3, allowing the user to visually and easily determine whether the image quality settings of the video camera 1 and the display quality settings of the display unit 207 of the external recorder 3 have been correctly set.

[0082] <Second embodiment>

[0083] Next, the second embodiment will be described. In the second embodiment, the first frame VF1 and the second frame VF2 are synthesized to generate third moving image data (third frame VF3). In other words, in this embodiment, the first and second frames are synthesized to generate third moving image data that represents the difference between the animation image quality setting and the display image quality setting.

[0084] Along Figures 7 to 9 , a specific example of the third dynamic image data of this embodiment is described.

[0085] Figure 7 This is a schematic diagram showing an example of third moving image data according to the present embodiment. Figure 7 The third frame VF3(2) constituting the third moving image data is formed by arranging and synthesizing the first frame VF1 constituting the first moving image data and the second frame VF2 constituting the second moving image data. Specifically, the first frame VF1 is arranged on the left side and the second frame VF2 is arranged on the right side, facing each other, and synthesized to form the third frame VF3(2). By arranging the first frame VF1 and the second frame VF2 in this way, the user can easily visually distinguish the difference between the animation image quality setting and the display image quality setting.

[0086] Figure 8 This is a schematic diagram showing an example of third moving image data according to the present embodiment. Figure 8 The third frame VF3 (3) constituting the third dynamic image data is formed by overlapping and synthesizing the first frame VF1 constituting the first dynamic image data and the second frame VF2 constituting the second dynamic image data. Specifically, Figure 8 As shown, the second frame VF2 is displayed superimposed on a portion of the first frame VF1 as the third frame VF3 (3). In this way, by superimposing the second frame VF2 on a portion of the first frame VF1, the user can easily visually distinguish the difference between the animation image quality setting and the display image quality setting.

[0087] Figure 9 This is a schematic diagram showing an example of third moving image data according to the present embodiment. Figure 9 The third frame VF3 (4) constituting the third moving image data is formed by synthesizing a portion of the first frame VF1 constituting the first moving image data and a portion of the second frame VF2 constituting the second moving image data. Specifically, the left half of the image of the first frame VF1 is arranged on the left side, and the right half of the image of the second frame VF2 is arranged on the right side, thereby synthesizing the third frame VF3 (4). By synthesizing the left half of the image of the first frame VF1 and the right half of the image of the second frame VF2 in this way, the user can easily visually distinguish the difference between the animation image quality setting and the display image quality setting.

[0088] Figure 10 This is a flowchart illustrating the imaging method (and a program for executing the imaging method) according to this embodiment.

[0089] First, the first moving image data processing unit 121 of the camera 1 obtains the video quality setting "MV_SET" of the camera 1 (step S301). Next, the monitor quality setting "MON_SET" of the external recorder 3 is transmitted from the external recorder 3 (CPU 205) to the camera 1 via the HDMI cable 5, and the second moving image data processing unit 123 of the camera 1 obtains the monitor quality setting "MON_SET" (step S302).

[0090] Next, the CPU 107 acquires moving image data (RAW) from the imaging element 105 (step S303). The first moving image data processing unit 121 then generates first moving image data corresponding to "MV_SET" (step S304). Furthermore, the second moving image data processing unit 123 generates second moving image data corresponding to "MON_SET" (step S305).

[0091] CPU 107 then determines whether a recording start instruction signal has been received and begins recording the video (step S306). If CPU 107 determines that video recording is in progress, first video data processing unit 121 transmits the first video data to external recorder 3 (step S307). On the other hand, if CPU 107 determines that video recording is not in progress, third video data processing unit 125 generates third video data by synthesizing the first video data and the second video data (step S313). The third video data is then transmitted from imaging device 1 to external recorder 3 (step S314).

[0092] In addition, the following steps S308 to S312 are Figure 5 Steps S106 to S110 described in are corresponding, so their description is omitted.

[0093] As described above, in this embodiment, the third moving image data, which is a composite of the first frame VF1 and the second frame VF2, is generated by the third moving image data processing unit 125. The user can then easily visually determine whether the image quality settings of the video camera 1 and the display quality settings of the display unit 207 of the external recorder 3 are correctly set by checking the third moving image data displayed on the display unit 207 of the external recorder 3.

[0094] <Other example 1>

[0095] Next, another example 1 will be described.

[0096] In another example 1, the CPU 107 displays the comparison result between the moving image quality setting and the display image quality setting on the display unit (rear display or electronic viewfinder) 113 of the imaging device 1 .

[0097] Figure 11 1 is a diagram showing the comparison result displayed on the rear display of the imaging device 1. The CPU 107 displays the comparison result 7 between the video image quality setting and the display image quality setting on the rear display. Figure 11In the example shown, the video quality settings for camera 1 are set to "BT.2100" for the video mode and "Limited" for the video range. Furthermore, the display quality settings for external recorder 3 are set to "BT.709" for the video mode and "Limited" for the video range. If the video quality settings for camera 1 and the display quality settings for external recorder 3 match, an "O" (or "OK") is displayed; if they do not match, an "X" (or "NG") is indicated. By displaying whether the setting conditions match, or the difference in the setting conditions, the user can easily determine which setting on external recorder 3 should be changed to match the video quality setting on camera 1.

[0098] <Other example 2>

[0099] Next, another example 2 will be described.

[0100] In another example 2, the imaging device 1 and the external recorder 3 are connected wirelessly.

[0101] Figure 12 1 is a block diagram showing the functions of the camera 1 and the external recorder 3 of this example. Figure 2 Parts that have already been explained are marked with the same symbols and the explanation is omitted.

[0102] The camera 1 and the external recorder 3 are connected wirelessly. Specifically, in the camera 1, the connection unit 109 includes a communication unit (antenna) 110A, which is wirelessly connected to the communication unit (antenna) 110B to transmit the captured moving image data to the external recorder 3. Specific examples of wireless connections include Wi-Fi, UWB (Ultra Wide Band), wireless HDMI, and wireless SDI (Serial Digital Interface).

[0103] <Other example 3>

[0104] Next, another example 3 will be described.

[0105] In another example 3, even when the display image quality setting of the external recorder 3 differs from the video image quality setting of the imaging device 1, control is performed on the imaging device 1 side so that a live preview image in which exposure and color can be confirmed is obtained. For example, this example is effective when there is no display image quality setting of the external recorder 3 that matches the video image quality setting of the imaging device 1.

[0106] Figure 13 This is a flowchart illustrating the imaging method (and a program for executing the imaging method) of this example.

[0107] First, the first moving image data processing unit 121 of the camera 1 obtains the video quality setting "MV_SET" of the camera 1 (step S401). Then, the monitor quality setting "MON_SET" of the external recorder 3 is transmitted from the external recorder 3 to the camera 1, and the second moving image data processing unit 123 of the camera 1 obtains the monitor quality setting "MON_SET" (step S402).

[0108] Next, the imaging device 1 acquires moving image data (RAW) from the imaging element 105 (step S403). The first moving image data processing unit 121 then generates first moving image data through first image processing corresponding to "MV_SET" (step S404). Next, the second moving image data processing unit 123 generates second moving image data through second image processing corresponding to "MON_SET" (step S405). Next, the imaging device 1 transmits the first moving image data to the external recorder 3 (step S406). Next, the imaging device 1 transmits the second moving image data to the external recorder 3 (step S407).

[0109] Then, CPU 107 determines whether or not animation recording is in progress (step S408). If CPU 107 determines that animation recording is in progress, external recorder 3 records the first moving image data (step S409). On the other hand, if CPU 107 determines that animation recording is not in progress, external recorder 3 displays the second moving image data on display unit (display) 207 (step S410).

[0110] In addition, the following steps S411 to S415 are Figure 5 Steps S106 to S110 described in are corresponding, so their description is omitted.

[0111] In this manner, the imaging device 1 generates first moving image data with a movie quality setting and second moving image data with a display quality setting, and transmits these data to the external recorder 3. Then, when recording a movie, the external recorder 3 records the first moving image data and displays the second moving image data on the display unit (display) 207. Thus, even if the external recorder 3 does not have a display quality setting that matches the movie quality setting of the imaging device 1, a live preview image capable of confirming exposure and color can be displayed on the display unit 207.

[0112] As mentioned above, although the example of this invention was demonstrated, this invention is not limited to the said embodiment, It is a matter of course that various deformation|transformation is possible within the range which does not deviate from the meaning of this invention.
