[0011] The imaging device of the present invention is an imaging device having a first monitor unit and a first processor, and when a first shooting mode in which the image format is restricted is selected, the first processor outputs user interface information related to shooting to the first monitor unit and restricts the output of live view to the first monitor unit.

[0012] In the first photographing mode, the first processor preferably locks the photographing operation by the first member and releases the lock based on the operation of the second member. When the lock is released, the first processor preferably outputs information indicating that the photographing operation by the first member is valid as user interface information. When a photographing operation is performed while the photographing operation is locked, the first processor preferably outputs information indicating that the photographing operation is invalid.

[0015] When the number of images captured in the first imaging mode reaches a predetermined number, the first processor preferably stores the series of image data obtained by the imaging in a recording medium as a single unit format. When the first imaging mode is terminated, the first processor preferably transitions to a second imaging mode in which the restriction on output to the first monitor is lifted.

[0016] In the first imaging mode, the first processor preferably restricts video among image formats. The first processor preferably outputs a predetermined number of images as user interface information. In the first imaging mode, the first processor preferably stores a series of image data obtained by imaging in a recording medium as a single unit format with a display restriction on the first monitor, and releases the display restriction when termination of the first imaging mode is selected.

[0017] In the first shooting mode, it is preferable that the first processor stores a series of image data obtained by shooting in a second storage area of ​​a recording medium in which a first storage area compliant with the DCF standard and a second storage area non-compliant with the DCF standard have been created.

[0018] The first processor preferably stores a series of image data obtained by photographing in the first photographing mode under a second directory that does not comply with the DCF standard and that is generated in the second storage area, and the first processor preferably stores image data obtained in the second photographing mode, in which the image format is not restricted, under a first directory in the first storage area.

[0019] The first processor preferably creates a second directory in the second storage area each time the first shooting mode is selected, and the first processor preferably creates a management file under the second directory that records information about the image data.

[0020] It is preferable that the first directory and the second directory in the first storage area are distinguishable from each other, and that the first directory and the second directory are hierarchically organized according to the same rules.

[0021] When the first processor receives a first instruction, it is preferable that the first processor makes the image data stored in the second storage area displayable on the first monitor based on the first instruction. It is preferable that the first processor outputs an image of list data that lists thumbnail images of the image data to the first monitor. When the first processor receives a second instruction from the external device, it is preferable that the first processor moves the image data stored in the second storage area to the first storage area based on the second instruction.

[0022] The present invention is an application program to be executed by an information processing device connected to the imaging device of the present invention described above and having a second monitor unit and a second processor, wherein the second processor either executes a third instruction to make image data stored in a second storage area displayable on the second monitor unit, or executes a fourth instruction to move image data stored in the second storage area to a first storage area.

[0023] It is preferable that the second processor receives image data transmitted from the imaging device based on the first instruction, and outputs an image of list data that lists thumbnail images of the image data to the second monitor unit based on the image data.

[0024] The present invention is an imaging system connected to the imaging device of the present invention described above and comprising an information processing device having a second monitor unit and a second processor, wherein the second processor either executes a third instruction to make image data stored in a second storage area displayable on the second monitor unit, or executes a fourth instruction to move the image data stored in the second storage area to the first storage area.

[0025] The present invention provides an imaging method using an imaging device having a first monitor unit and a first processor, in which the first processor includes a step of outputting user interface information related to imaging to the first monitor unit and restricting output of live view to the first monitor unit when a first imaging mode in which the image format is restricted is selected.

[0026] It is preferable that the first processor has a step of saving, in the first shooting mode, a series of image data obtained by shooting in a second storage area of ​​a recording medium in which a first storage area compliant with the DCF standard and a second storage area non-compliant with the DCF standard have been created.

[0027] The present invention is an imaging program that uses an imaging device having a first monitor unit and a first processor, and causes the first processor to execute a function of outputting user interface information related to imaging to the first monitor unit and restricting the output of live view to the first monitor unit when a first imaging mode in which the image format is restricted is selected.

[0028] It is preferable to cause the first processor to execute a function of storing, in a first shooting mode, a series of image data obtained by shooting in a second storage area of ​​a recording medium in which a first storage area compliant with the DCF standard and a second storage area non-compliant with the DCF standard have been created.

[0029] The present invention is an imaging device having a first monitor unit and a first processor, the imaging device having a first shooting mode that imposes restrictions on digital functions, and when the first shooting mode is selected, the first processor preferably imposes at least two of the following restrictions on the digital functions: restricting the image format; restricting the output of live view to the first monitor unit; restricting the saving of a series of image data obtained by shooting in the first shooting mode in a format other than the format of a single unit; restricting the number of shots; and restricting the second shooting operation following the first shooting operation. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0032] 1, imaging device 10 includes camera body 11 and lens barrel 12. Camera body 11 has a horizontally elongated box shape in which the left-right dimension is longer than the up-down dimension when viewed from the front. It is preferable that imaging device 10 is a digital camera or the like.

[0033] Camera body 11 is provided with grip 11A at the left end when viewed from the front. Grip 11A is semi-cylindrical and connects to the front and back of camera body 11, making it easy for the user to hold. Lens barrel 12 is disposed on the front of camera body 11, and is provided with imaging optical system 13. Imaging optical system 13 forms an image of subject light on imaging element 21, which is disposed on optical axis OA.

[0034] The top surface of the camera body 11 is provided with a mode dial 14, a release switch 15, a power switch 16, a lever 17, and the like. The mode dial 14 is used to gradually change the exposure amount, etc. In addition to the lens barrel 12, the front surface of the camera body 11 is provided with a flash unit 18 and an illumination unit 19. The flash unit 18 illuminates the subject with illumination light in conjunction with a shutter release when the exposure value of the subject is below a certain level or when the subject is forcibly exposed to light when the image capture device 10 is in still image capture mode. On the other hand, the illumination unit 19 constantly illuminates the subject with illumination light when the image capture device 10 is in video capture mode.

[0035] 2, the lever 17 is provided above the grip 11A. The lever 17 is provided stacked with the mode dial 14 and the release switch 15. The lever 17 is attached so as to be rotatable around the central axis CL of the mode dial 14. The lever 17 can be rotated by the user, and details of the rotation will be described later.

[0036] The power switch 16 is a push-button switch, and is located near the mode dial 14 and the lever 17. When the power switch 16 is pressed, the power of the imaging device 10 is alternately switched between on and off states.

[0037] The camera body 11 has a built-in imaging element 21 (see FIG. 3 ). The imaging element 21 is held in a holder (not shown) and fixed to the image plane side of the lens barrel 12. The imaging element 21 has a function of capturing still images and moving images, and is, for example, a complementary metal oxide semiconductor (CMOS) image sensor, a charge coupled device (CCD) image sensor, or an organic thin-film imaging element. The imaging element 21 is an imaging element that is placed horizontally, i.e., when the top surface of the camera body 11 faces vertically upward, its vertical length is shorter than its horizontal length. However, the imaging element 21 is not limited to this, and may also be an imaging element that is placed horizontally, i.e., when the top surface of the camera body 11 faces vertically upward, its vertical length is longer than its horizontal length.

[0038] The rear surface of the camera body 11 is provided with a display 22 (first monitor), an electronic viewfinder 23, and a sub-display 24. The display 22 is an LCD (Liquid Crystal Display) or an OLED (Organic Electroluminescent Display), etc., and is configured as a touch screen that can be operated by a user by touch. The display 22 is used for live view display, recorded image display, setting menu display, etc. In live view display, a recorded image of a subject captured by the image sensor 21 is displayed on the display 22 in real time.

[0039] The sub-display 24 displays information about image quality such as color, and is configured as a touch screen that can be touched by the user, similar to the main display 22. The main display 22 corresponds to the monitor unit in the claims, but the monitor unit may also include the electronic viewfinder 23 or the sub-display 24.

[0040] The electronic viewfinder 23 is provided on the top of the camera body 11. The electronic viewfinder 23 displays a live view, and displays in real time a recorded image of a subject captured by the image sensor 21. The electronic viewfinder 23 can be turned on or off as needed, and can be switched to display on the display 22.

[0041] The rotation operation of lever 17 will be described below. As shown in Figure 3(A), when power switch 16 is off, lever 17 is restricted from rotating by a locking mechanism (not shown), and is locked in a position along the back surface of camera body 11. "A position along the back surface of camera body 11" means that lever 17 is in a position where it does not protrude from the back surface of camera body 11 when viewed from above.

[0042] As shown in FIG. 3(B), when the power switch 16 is switched from off to on, the rotation restriction on the lever 17 is released, and the lever 17 is set to the normal position, rotated slightly counterclockwise from the rear of the camera body 11. Unless the user operates the lever 17, the lever 17 remains in the normal position. Then, as shown in FIG. 3(C), the lever 17 can be rotated counterclockwise from the normal position to perform the film winding operation. This rotation operation is used to unlock the shooting operation in film camera mode (unlocking the shooting operation will be described later).

[0043] Specifically, to wind the film using lever 17, the user places their finger on lever 17 and moves it counterclockwise, causing it to rotate. When lever 17 has rotated a certain angle, the user releases their finger from lever 17, and lever 17, biased by a spring or the like, automatically rotates counterclockwise and returns to its normal position. This completes the film winding operation.

[0044] The following describes the electrical configuration of the imaging device 10. As shown in Fig. 4, the control unit 31 is made up of a microcomputer including a CPU, a ROM (Read Only Memory) that stores programs and parameters used by the CPU, and a RAM (Random Access Memory) that is used as a work memory for the CPU (none of which are shown), and functions as a first processor that controls each unit of the imaging device 10.

[0045] When the lever 17 is rotated, a signal detecting the amount of rotation is sent to the control unit 31. The control unit 31 also receives a mode switching signal from the mode dial 14, a release signal from the release switch 15, and a power on / off signal from the power switch 16.

[0046] The shutter unit 32 is, for example, a focal plane shutter, and is disposed between the imaging optical system 13 and the imaging element 21. The shutter unit 32 is provided so as to be able to block the optical path between the imaging optical system 13 and the imaging element 21, and is capable of changing between an open state and a closed state. The shutter unit 32 is driven by a shutter motor 33. A motor driver 34 controls the driving of the shutter motor 33.

[0047] The shutter unit 32 is in an open state when capturing live view images and moving images. When capturing still images, the shutter unit 32 is variable from an open state to a closed state when the release switch 15 is not operated, and is variable from the closed state to the open state when the release switch 15 is operated. When capturing a preview image in moving image capture mode, the shutter unit 32 operates in the same way as when capturing a moving image, and when capturing a preview image in still image capture mode, the shutter unit 32 operates in the same way as when capturing a still image.

[0048] The imaging element 21 is driven and controlled by the control unit 31. The imaging element 21 has a light receiving surface made up of a plurality of pixels (not shown) arranged in a two-dimensional matrix. Each pixel includes a photoelectric conversion element, and photoelectrically converts the subject image formed on the light receiving surface by the imaging optical system 13 to generate an imaging signal.

[0049] The image sensor 21 also includes signal processing circuits (none of which are shown), such as a noise reduction circuit, an auto-gain controller, and an A / D conversion circuit. The noise reduction circuit performs noise reduction processing on the image signal. The auto-gain controller amplifies the level of the image signal to an optimum value. The A / D conversion circuit converts the image signal into a digital signal and outputs it from the image sensor 21 to the bus line 36. The output signal of the image sensor 21 is image data (so-called RAW data) having one color signal for each pixel.

[0050] The image memory 35 stores one frame of image data output to the bus line 36. The image data processing unit 37 reads one frame of image data from the image memory 35 and performs known image processing such as matrix calculation, demosaic processing, gamma correction, luminance / color difference conversion, and resizing.

[0051] The display driver 38 sequentially inputs one frame of image data that has been image-processed by the image data processing unit 37 to the display 22 or the electronic viewfinder 23. The display 22, for example, sequentially displays live view images at regular intervals. The display 22 is touch-operable, and by touching an operation icon (not shown) or the like displayed on the display 22, an operation or selection corresponding to the operation icon is performed.

[0052] The card I / F (Interface) 41 is incorporated in a card slot (not shown) provided in the camera body 11 and is electrically connected to a memory card 42 inserted into the card slot. The memory card 42 can be inserted into and removed from the card slot by the user. Specifically, the card I / F 41 stores image data that has been image-processed by the image data processing unit 37 into the memory card 42. When playing back and displaying image data stored in the memory card 42, the card I / F 41 reads the image data from the memory card 42. Note that the image recording unit is not limited to a configuration in which data is recorded on a recording medium such as a memory card, and may be a recording device such as an SSD (Solid State Drive).

[0053] The imaging device 10 has multiple shooting modes, such as a normal mode (second shooting mode) and a film camera mode (first shooting mode). Common modes include a still image shooting mode and a video shooting mode. The film camera mode is a mode in which the image format is limited and which reproduces the analog feel of a film camera. To switch from the normal mode to the film camera mode, as shown in FIG. 5, by touching the sub-display 24, the display 22 switches from the normal mode screen shown in (A) to the film camera mode screen shown in (B). Switching from the film camera mode to the normal mode occurs when the user selects to end the film camera mode or when a predetermined number of shots have been taken in the film camera mode.

[0054] When film camera mode is selected, the control unit 31 outputs user interface information related to shooting to the display 22, and restricts the output of live view to the display 22. Specifically, as shown in FIG. 6 , the display area of ​​the display 22 displays, as user interface information related to shooting, a non-touchable area 50 where the user cannot touch the screen, such as the number of shots, and a touchable area 51 where the user can touch the screen, such as manual focus. Furthermore, restricting the output of live view to the display 22 includes not displaying a live view image on the display 22 in film mode, as in normal mode. Furthermore, in film mode, it is preferable to restrict video, one of the image formats, so that it is not displayed on the display 22.

[0055] "PROVIA" displayed on the sub-display 24 is one of the film simulations, which is a function that allows you to change the color and contrast to suit your shooting intentions, just like changing the film in a camera. By touching the sub-display 24, you can switch to a film simulation other than "PROVIA" (for example, "VELVIA").

[0056] The touch-non-operable area 50 displays a remaining battery level indicator 53, an aperture value indicator 54, a number of shots indicator 55, a number of remaining shots indicator 56, a lever status indicator 57, a flash on / off indicator 58, and a date indicator 59. The remaining battery level indicator 53 shows the remaining battery level with vertical lines within a shape that represents a battery. The more vertical lines there are, the more remaining battery level there is. The aperture value indicator 54 displays the aperture value numerically. The number of shots indicator 55 displays the current number of shots. The number of remaining shots indicator 56 displays the number of remaining shots, which is the number of shots that is predetermined when film camera mode is started. The number of remaining shots is preferably set to, for example, 72, 36, or 24, corresponding to the number of shots that can be taken with camera film.

[0057] The lever status display unit 57 displays whether or not the lever 17 has been operated to wind the film in film camera mode. Details of the lever status display unit 57 will be described later. The flash on / off display unit 58 displays "ON" when the flash unit 18 is turned on, and "OFF" when the flash unit 18 is turned off. The date display unit 59 displays the current date, and in film camera mode, the currently displayed date is superimposed on the image.

[0058] The touch operable area 51 displays an AF / MF switching section 60, a date ON / OFF switching section 61, and an MF focus distance operation section 62. In the AF / MF switching section 60, the round button section 60a can be slid left and right; sliding the round button section 60a to the left switches to AF (Auto Focus), and sliding the round button section 60a to the right switches to MF (Manual Focus). Switching to MF enables operation of the MF focus distance operation section 62.

[0059] The date ON / OFF switching section 61 can be operated by pressing the round button section 61a, and by pressing the round button section 61a, it is possible to switch between date ON and date OFF. When the date is ON, the center of the round button section 61a lights up, and the date currently displayed in the date display section 59 is superimposed each time a photograph is taken. On the other hand, when the date is OFF, the center of the round button section 61a is unlit. In this case, the date is not superimposed even when a photograph is taken.

[0060] The MF focus distance operation unit 62 has a slider 62a, and the focus distance is set by sliding the slider 62a left or right. The MF focus distance operation unit 62 allows the focus distance to be set to "0.3 m," "1 m," "3 m," or "5 m." At "0.3 m," a logo is displayed showing an example of focusing on the face of one person. At "1 m," a logo is displayed showing an example of focusing on the upper body of one person. At "3 m," a logo is displayed showing an example of focusing on the upper bodies of two people. At "5 m," a logo is displayed showing an example of focusing on a landscape painting. By setting the slider 62a to each of the "0.3 m," "1 m," "3 m," or "5 m" positions, the corresponding focus distance can be set.

[0061] In film camera mode, the control unit 31 locks the shooting operation using the release switch 15 (first member) and unlocks the lock based on the operation of the lever 17 (second member). On the other hand, when the lock is released, the control unit 31 outputs information that the shooting operation using the release switch 15 is valid as user interface information. Furthermore, when a shooting operation is performed using the release switch 15, the control unit 31 outputs information regarding the number of shots as user interface information. Furthermore, the control unit 31 restricts the output of image data to the display 22 after shooting.

[0062] Specifically, as shown in Fig. 7(A), when switching from normal mode to film camera mode, the lever state display unit 57 displays "--", indicating that the film advance operation of the lever 17 has not been performed. Also, the number of shots display unit 55 indicates that the current number of shots is "0." In this state, shooting operations using the release switch 15 are locked, and even if the release switch 15 is operated, still images will not be captured or saved to the memory card 42.

[0063] Then, as shown in FIG. 7(B), by operating the lever 17 to wind the film, the lever status display unit 57 displays "OK," indicating that the lever 17 has been operated to wind the film. The "OK" display on the lever status display unit 57 indicates that the shooting operation using the release switch 15 is valid. In this state, the shooting operation using the release switch 15 is unlocked, and by operating the release switch 15, a still image is acquired and saved to the memory card 42. Then, when the shooting operation is completed, as shown in FIG. 7(C), the shot count display unit 55 changes the display of the current number of shots from "0" to "1," and the lever status display unit 57 resets the film winding operation and returns to displaying "--." Note that, when the shooting operation is completed, the display 22 maintains the display of the user interface information for the film camera mode (touch-operable and non-touch-operable areas), and does not display image data after shooting.

[0064] If a shooting operation is performed while the shooting operation is locked, the control unit 31 preferably outputs information that the shooting operation is invalid. Specifically, as shown in Fig. 8, it is preferable to flash a warning LED 65 (Light Emitting Diode) provided on the left side of the electronic viewfinder 23 to indicate that the shooting operation is invalid. Also, as shown in Fig. 9, it is preferable to flash "--" on the lever state display unit 57 to indicate that the shooting operation is invalid.

[0065] When the end of the film camera mode is selected, the control unit 31 preferably stores a series of image data obtained by shooting as a single unit in the memory card 42 (recording medium). Furthermore, when the film camera mode is ended, the control unit 31 transitions to the normal mode in which the restriction on output to the display 22 is lifted.

[0066] Specifically, as shown in FIG. 10(A), when ending the film camera mode midway, a predetermined touch operation is performed on the sub-display 24 to switch the film camera mode to an end screen. As a result, as shown in FIG. 10(B), a film camera mode end selection screen 66 is displayed on the main display 22. A cartridge image 67 indicating that a series of image data obtained by shooting will be saved in the form of a single unit, and an end selection button 68 are displayed on the film camera mode end selection screen 66. By touching the end selection button 68, the film camera mode is ended, and the series of image data obtained by shooting is saved in the form of a single unit on the memory card 42. As a result, as shown in FIG. 10(C), the mode transitions to the normal mode, the live view on the main display 22 is canceled, and the live view begins to be displayed on the main display 22.

[0067] It is preferable that in film camera mode, when the number of shots reaches a predetermined number, the control unit 31 disables the shooting operation using the release switch 15 and the unlocking of the shooting operation using the lever 17. Also, in film camera mode, when the number of shots reaches a predetermined number, the control unit 31 preferably saves a series of image data obtained by shooting as a single unit on the memory card 42. Also, when the film camera mode is ended, the control unit 31 transitions to normal mode, in which the restriction on output to the display 22 is lifted. Note that the above-mentioned predetermined number is output to the display 22 as the number of shots that can be taken, which is one of the user interface information.

[0068] Specifically, as shown in FIG. 11(A), when the number of shots reaches the maximum number of shots, "72," the lever status display 57 displays "OFF," indicating that shooting operations by winding the lever 17 are disabled. Accordingly, shooting operations by the release switch 15 are also disabled. Then, after a certain period of time, as shown in FIG. 11(B), a film camera mode termination screen 70 is displayed on the display 22. The film camera mode termination screen 70 displays a cartridge image 67, which indicates that a series of image data obtained by shooting will be saved as a single unit, and a message 71 indicating that the film camera mode has ended. This ends the film camera mode, and the series of image data obtained by shooting is saved as a single unit on the memory card 42. Then, by tapping the display 22, for example, the display switches to normal mode as shown in FIG. 11(C), and the live view display on the display 22 is no longer displayed, and the live view display begins to be displayed on the display 22.

[0069] In the film camera mode, it is preferable that a series of image data obtained by shooting is saved on the memory card 42 in a single unit format with a display restriction on the display 22. For example, as shown in FIG. 12, as a series of image data, each of the image data for the number of shots taken up to that point is saved on the memory card 42 as a thumbnail image group 73, in which each image data is represented by a thumbnail. During the film camera mode, the thumbnail image group 73 is restricted from being displayed on the display 22, so it is not displayed on the display 22 even if the playback button (not shown) is operated. On the other hand, when the film camera mode is ended, the display restriction on the thumbnail image group 73 is lifted, and it becomes possible to display the thumbnail image group 73 on the display 22.

[0070] It is preferable that the film camera mode is a mode that imposes restrictions on the digital functions of the imaging device 10. As restrictions on the digital functions, the control unit 31 preferably imposes at least two of the following restrictions: image format restrictions, restrictions on output to the live view display 22, restrictions on saving a series of image data obtained by shooting in the film camera mode in a format other than a single unit format, restrictions on the number of shots, and restrictions on a second shooting operation following a first shooting operation. In this embodiment, while saving in a format other than a single unit format (patrone image unit) is restricted in the film camera mode, if the image data is subsequently shot again in the film camera mode, the subsequent shot data may be added to the saved data in a single unit format obtained in the previous film camera mode.

[0071] Specifically, it is preferable to restrict image formats by permitting still images and restricting videos. It is preferable to restrict output of live view to the display 22 by not displaying live view on the display 22. It is preferable to restrict saving of a series of image data obtained by shooting in film camera mode in a format other than a single unit format by prohibiting saving in a format other than the thumbnail image group 73. It is preferable to restrict the number of shots by prohibiting taking more than the number of shots that can be taken when starting film camera mode. It is preferable to restrict the second shooting operation following the first shooting operation by prohibiting consecutive shooting operations using the release switch 15, and after the first shooting operation, it is preferable to unlock the shooting operation by operating the film advance lever 17 before allowing the second operation.

[0072] As shown in Fig. 13, the film camera mode can be set in 10 patterns, from mode 1 to mode 10. Mode 1 of the film camera mode imposes two restrictions: an image format restriction (image format restriction) and an output restriction to the live view display 22 (monitor output restriction). Mode 2 of the film camera mode imposes two restrictions: an image format restriction and a saving restriction (save restriction) in a format other than the format of one unit of a series of image data obtained by shooting in the film camera mode. Mode 3 of the film camera mode preferably imposes two restrictions: an image format restriction and a second shooting operation following a first shooting operation (shooting operation restriction).

[0073] Mode 4 of the film camera mode preferably imposes two restrictions: monitor output restriction and storage restriction. Mode 5 of the film camera mode preferably imposes two restrictions: monitor output restriction and shooting operation restriction. Mode 6 of the film camera mode preferably imposes two restrictions: storage restriction and shooting operation restriction. Mode 7 of the film camera mode preferably imposes three restrictions: image format restriction, monitor output restriction, and storage restriction. Mode 8 of the film camera mode preferably imposes three restrictions: image format restriction, monitor output restriction, and shooting operation restriction. Mode 9 of the film camera mode preferably imposes three restrictions: monitor output restriction, storage restriction, and shooting operation restriction. Mode 10 of the film camera mode preferably imposes four restrictions: image format restriction, monitor output restriction, storage restriction, and shooting operation restriction.

[0074] As described above, in film camera mode, you cannot immediately check the image you have taken, so you can enjoy the excitement that is characteristic of film cameras, such as the sense of anticipation of not knowing the result until it is developed and the experience of getting an image that is different from what you expected.In addition, even today, there is a group of users who are purchasing new film cameras, and new film cameras are still being released, so the inclusion of film camera mode fully meets the needs and desires of the market of users who enjoy the experience of taking pictures with a film camera and want to continue using film cameras.

[0075] The control unit 31 controls the execution, continuation, and termination of the film camera mode (first shooting mode). The control unit 31 acquires first information related to the insertion or removal of a memory card 42 (recording medium) that records imaging data of the imaging device 10, and restricts the film camera mode related to the functions of the imaging device 10 based on the first information. The first information is preferably information including the insertion or removal state of the memory card 42. Note that, in this embodiment, the restriction on the film camera mode is the termination of the film camera mode, but the restriction on the film camera mode also includes the case where only some of the functions of the film camera mode are stopped while the others are continued.

[0076] Specifically, when the film camera mode is activated, it is preferable that the control unit 31 performs a first control, which is a control to either execute the film camera mode or restrict the film camera mode, based on the first information. The film camera mode is activated by touching the sub-display 24, as described above. As shown in (A) of FIG. 14, the control unit 31 executes the film camera mode when the first information indicates that the memory card 42 is inserted (see FIG. 15). On the other hand, as shown in (B) of FIG. 14, when the first information indicates that the memory card 42 is removed (see FIG. 15), the control unit 31 terminates the film camera mode.

[0077] 14, a state in which "SD card" is included in a rectangular solid-line box represents an inserted state of the memory card 42, and a state in which "-" is included in a rectangular solid-line box represents an removed state of the memory card 42. The camera graphic represents the imaging device 10. The notation of the inserted or removed state and the camera is the same in the other drawings. Note that, although an SD card is given as the memory card 42 in this embodiment, other recording media (such as a USB memory) may also be used.

[0078] Next, when the film camera mode is executed, it is preferable that the control unit 31 outputs error information based on the first information. The error information may be displayed on the display 22 or may be output as sound, for example. After outputting the error information, it is preferable that the control unit 31 performs second control, which is control to either continue the film camera mode or restrict the film camera mode, based on the first information.

[0079] 16, if the first information changes from an inserted state to a removed state during film mode, error information is output in the imaging device 10. After the error information is output, if the memory card 42 is inserted and the first information changes to an inserted state as shown in (A) and (B), control is performed to either continue the film camera mode or end the film camera mode. On the other hand, if the memory card 42 is not inserted and the first information remains in the removed state even after a certain period of time has passed as shown in (C), control is performed to end the film camera mode.

[0080] As a control to be performed after the error information is output, when the first information indicates an inserted state, the control unit 31 preferably determines whether or not the memory card 42 has a first attribute that was assigned by executing the film camera mode. As shown in Fig. 17, if the first attribute is present, the film camera mode continues (see Fig. 16(A)), and if the first attribute is not present, the film camera mode ends (see Fig. 16(B)). Note that a case where the first attribute is not present may occur, for example, when the reinserted memory card 42 is a different card from the memory card 42 before insertion, as shown in Fig. 18.

[0081] The first attribute is created as a management file in the memory card 42 when the film camera mode is started for the first time (see management file 107 in FIG. 24). The management file includes not only the first attribute but also the second attribute, which will be described later. The management file preferably includes the start date and time of the film camera mode, the end date and time, the number of shots that can be taken when the film camera mode starts, the memory card capacity when the film camera mode starts, the film simulation / filter settings for the film camera mode, etc.

[0082] Furthermore, as a control to be performed after the error information is output, when the first information indicates an inserted state, the control unit 31 preferably determines whether or not the first attribute is present. As shown in Fig. 17, if the first attribute is present and the second attribute assigned to the data on the memory card 42 in association with the history record has not been changed from the outside (no modification), the film camera mode continues (see Fig. 16(A)). On the other hand, if the first attribute is present and the second attribute has been changed from the outside (modified), the film camera mode ends (see Fig. 16(B)). Note that an external modification to the second attribute may occur, for example, when a file / folder is copied, deleted, or modified within the memory card 42, as shown in Fig. 19.

[0083] As a method for determining whether external changes have been made, for example, if the card capacity of memory card 42 after reinsertion is within a predetermined range, calculated by subtracting the image data capacity of the number of shots taken up to that point from the memory card capacity at the start of film camera mode, which is one of the second attributes, it is determined that no changes have been made, and if it is not within the predetermined range, it is determined that changes have been made.

[0084] Examples of cases where film camera mode continues after error information is output are: If the removed memory card 42 is inserted without tampering with the data, etc. When some image files other than those in the current film camera mode are deleted and memory card 42 is inserted There is.

[0085] On the other hand, examples of when the film camera mode ends after error information is output are as follows: When some of the image files being taken in the current film camera mode are deleted and memory card 42 is inserted When another memory card 42 with the same folder structure as the memory card 42 is inserted When you insert a memory card 42 that has some files written to it If you erase the management file and insert memory card 42 If you delete all image files and insert memory card 42 If another memory card is inserted If you insert a cloned memory card 42 When the same memory card 42 is inserted with protection When a memory card 42 used in another imaging device is inserted (if the memory card capacity is smaller than that of the memory card used when shooting) When you replace the memory card 42 with another imaging device in film camera mode There is.

[0086] Furthermore, when the film camera mode is executed, if the power of the imaging device 10 is turned off and then turned back on, it is preferable that the control unit 31 performs a third control, which is a control to either continue the film camera mode or restrict the film camera mode, based on the first information.

[0087] 20, when the power is turned OFF during the film mode, as shown in (A), (B), and (C), if the same memory card 42 remains inserted and the inserted state of the first information is maintained until the power is turned ON again, as shown in (A), the film camera mode continues. Also, as shown in (B) and (C), if the memory card 42 is removed after the power is turned OFF and then inserted when the power is turned ON, and the first information changes from the inserted state to the removed state, the control unit 31 performs control to either continue the film camera mode or restrict the film camera mode.

[0088] As a control when the power is turned back on, if the imaging device 10 is turned off and then turned back on, the control unit 31 preferably determines whether or not the first attribute exists. As shown in Fig. 17, if the first attribute exists, the film camera mode continues (see Fig. 20(B)), and if the first attribute does not exist, the film camera mode ends (see Fig. 20(C)).

[0089] Furthermore, as a control when the power is cycled, when the power of the imaging device 10 is turned off and then turned back on, the control unit 31 preferably determines whether or not the first attribute is present. As shown in Fig. 17, if the first attribute is present and the second attribute has not been changed externally (no modification), the film camera mode continues (see Fig. 20(B)). On the other hand, if the first attribute is present and the second attribute has been changed externally (modification), the film camera mode ends (see Fig. 20(C)).

[0090] In addition, if the power is turned off while in film camera mode, the film camera mode will continue as follows: After removing the memory card 42, if you insert the removed memory card 42 without tampering with the data, and then turn the power on After removing the memory card 42, you insert the memory card 42 from which some image files other than those in the current film camera mode have been deleted, and then turn the power on. There is.

[0091] On the other hand, when the power is turned off and the memory card 42 is removed during the film camera mode, the film camera mode is ended as follows: When you insert a memory card 42 from which some of the image files taken in the current film camera mode have been deleted and turn the power on When another memory card 42 with the same folder structure as the memory card 42 is inserted and the power is turned on When you insert a memory card 42 with some files written on it and turn the power on When you insert a memory card 42 from which the management file has been deleted and turn the power on When you insert a memory card 42 from which all image files have been deleted and turn the power on When another memory card is inserted and the power is turned on When the cloned memory card 42 is inserted and the power is turned on When the same protected memory card 42 is inserted and the power is turned on When the power is turned on without inserting a memory card 42 If the same memory card 42 is inserted after the power is turned on When a memory card 42 used in another imaging device is inserted and the power is turned on (when the memory card capacity is smaller than that of the memory card used when shooting) Replace the memory card 42 in film camera mode with another imaging device and turn the power on. If you set In addition, it is also preferable to end film camera mode if the battery is removed without turning the power off during film camera mode.

[0092] Next, when the film camera mode is ended, the control unit 31 preferably performs initialization related to the film camera mode. As shown in FIG. 21, initialization is preferably a process of discontinuing the use of the first setting value set in the first shooting in the film camera mode as the second setting value set in the second shooting, which is the next film camera mode. By performing initialization, the setting value used in the previous film camera mode is not carried over (reset) to the next film camera mode. Here, the first setting value or the second setting value may be, for example, the number of shots that can be taken, the film simulation pattern, the exposure amount set with the mode dial 14, the aperture value, etc. Note that when the film camera mode is ended, the normal mode is automatically executed (see FIGS. 10 and 11). Therefore, a new startup operation is required to start the next film camera mode.

[0093] Note that the execution and termination of the film camera mode may be controlled based on information different from the first information. When the memory card 42 is inserted, the control unit 31 may acquire second information related to the attributes of the memory card 42 and restrict the film camera mode based on the second information. Specifically, the attributes preferably include either a first attribute assigned to the memory card 42 upon execution of the film camera mode or a second attribute assigned to the data on the memory card 42 in relation to the history record. The first attribute and the second attribute are the same as those described above.

[0094] 22, if the second information has the first attribute, or if the second information has the first attribute and the second attribute has not been altered, the film camera mode is executed when the memory card 42 is inserted. On the other hand, if the second information does not have the first attribute, or if the second attribute has the first attribute and the second attribute has been altered, the film camera mode is terminated.

[0095] Next, the imaging method of the present invention will be described with reference to the flowchart in FIG. 23. When the user touches the sub-display 24, the film camera mode is activated. The film camera mode is a shooting mode in which the image format is restricted. The control unit 31 acquires first information regarding the insertion or removal of the memory card 42 that records imaging data of the imaging device 10, and performs a step of restricting the film camera mode based on the first information. In the film camera mode restricting step, the control unit 31 executes the film camera mode if the first information indicates that the memory card 42 is inserted. On the other hand, the control unit 31 terminates the film camera mode if the first information indicates that the memory card 42 is removed.

[0096] When the film camera mode is executed (selected), a step is performed in which user interface information related to photography is output to the display 22 and the output of the live view to the display 22 is restricted. The display of the user interface information and the restriction on the live view output continue during the film camera mode. Then, when the film camera mode is ended, the mode is switched from the film camera mode to the normal mode. By switching to the normal mode, the live view is displayed on the display 22.

[0097] In the imaging method of the present invention, it is preferable to perform a step in which, in film camera mode, a series of image data obtained by shooting is stored in a second storage area of ​​memory card 42 in which a first storage area 100 compliant with the DCF standard and a second storage area 101 not compliant with the DCF standard have been created.

[0098] The imaging program of the present invention is a program that causes the control unit 31 to execute a function of outputting user interface information related to imaging to the display 22 and limiting the output of live view to the display 22. The imaging program of the present invention is installed in the imaging device 10 when the imaging device 10 is manufactured, and is preferably installed in the imaging device 10 via a network or the like after the imaging device 10 has been shipped.

[0099] In addition, in the imaging program of the present invention, it is preferable that the control unit 31 also executes a function of saving the first memory area 100 compliant with the DCF standard and the second memory area 101 non-compliant with the DCF standard in the second memory area of ​​the generated memory card 42.

[0100] In film camera mode, in order to restrict display on the display 22, the series of image data obtained by shooting in film camera mode is saved in a manner different from that used in normal mode. As shown in Fig. 24, in film camera mode, the control unit 31 saves the series of image data obtained by shooting in second storage area 101 of memory card 42, which has created a first storage area 100 that complies with the DCF standard and a second storage area 101 that does not comply with the DCF standard. As a result, the image data in film camera mode is not displayed on the display 22. The format of the saved image data is preferably a common image format that can be acquired and viewed by both dedicated applications and general-purpose devices.

[0101] Specifically, the control unit 31 saves a series of image data 105 obtained by shooting in film camera mode under a second directory 103 that does not conform to the DCF standard and is created in the second storage area 101. The file names of the image data saved under the second directory 103 preferably indicate that the mode is film camera mode (for example, FCM) in addition to a number indicating the order in which the images were taken (FCM001, FCM002, FCM003, etc. in FIG. 24). Also, under the second directory 103, a management file 107 that records information about the image data is created. As described above, the management file 107 is used to determine whether to return to film camera mode when the memory card 42 is inserted or removed during film camera mode.

[0102] Meanwhile, the control unit 31 stores image data 106 obtained in the normal mode under the first directory 102 in the first storage area 100. It is preferable that the file names of the image data stored under the second directory 103 include numbers indicating the order in which they were captured (001, 002, 003, etc. in FIG. 24).

[0103] The control unit 31 generates the second directory 103 in the second storage area 101 each time the film camera mode is selected. Similarly, the control unit 31 generates the first directory 102 in the first storage area 100 each time the normal mode is selected. The first directory 102 and the second directory 103 are distinguishable from each other. Therefore, the first directory 102 and the second directory 103 are hierarchically organized according to the same rules. Specifically, new directory numbers are assigned to the first directory 102 and the second directory 103 each time either the normal mode or the film camera mode is selected, so as not to overlap with directory numbers that have already been assigned. Note that the second storage area 101 may be hierarchically organized according to the same rules as the first storage area 100, or may follow its own directory structure and naming rules, or may apply part of the directory structure and naming rules of the DCF standard.

[0104] For example, if selection is first made in the order of normal mode, normal mode, film camera mode, and film camera mode, as shown in Fig. 25, a first directory 102a numbered "100" is generated in the first storage area 100, followed by a first directory 102b numbered "101". Thereafter, a second directory 103a numbered "102" is generated in the second storage area 101, followed by a second directory 103b numbered "103". As described above, each directory can be identified because it has a different number, and even if the second directory 103 is moved to the first storage area 100, it does not overlap with the first directory 102 already in the first storage area 100, so there is no risk of overwriting or the like.

[0105] When the control unit 31 acquires the first instruction, it enables the image data stored in the second storage area 101 to be displayed on the display 22 based on the first instruction. The first instruction is preferably an instruction to end the film camera mode. In response to this, the control unit 31 outputs an image of list image data that lists thumbnail images of the image data to the display 22. The list image data is preferably the thumbnail image group 73 (see FIG. 12). Note that the first instruction may be an instruction from the imaging device 10, or an instruction from an external device such as an information processing device (see information processing device 110 in FIG. 27).

[0106] Furthermore, as shown in FIG. 26 , when a second instruction is received from an external device, the control unit 31 moves the image data stored in the second storage area 101 to the first storage area 100 based on the second instruction. The external device is a device other than the imaging device 10 that is connected to the imaging device 10 via a wired or wireless connection, and is preferably, for example, an information processing device such as a smartphone (see the information processing device 110 in FIG. 27 ). The second instruction is an instruction to move the image data stored in the second storage area 101 of the memory card 42 to the first storage area 100. This allows image data in film camera mode to be moved to the first storage area 100 and displayed on the display 22 based on an instruction from the external device, not an instruction from the imaging device 10. Note that the processing based on the second instruction includes not only physical movement of image data but also structural movement, such as attribute changes. The second instruction may also move the management file 107 to the first storage area 100 in addition to the image data alone.

[0107] As described above, by saving image data obtained in film camera mode, images can be immediately deleted while film camera mode is active, providing a film-like shooting experience. Meanwhile, after exiting film camera mode, users with limited equipment or environments can view images by directly accessing the media on a general-purpose device such as a PC, without using dedicated equipment or applications that require ongoing maintenance and operating costs. This provides a means of viewing images for a variety of users, including those in countries where general-purpose smartphone operating systems are not permitted, and those who own smartphones but not PCs. Images can be viewed using general-purpose devices, dedicated devices, dedicated applications, or other devices and applications capable of handling digital images.

[0108] As shown in FIG. 27 , image data obtained by shooting in film camera mode with the imaging device 10 may be transferred to an information processing device 110 other than the imaging device 10 and displayed thereon. The information processing device 110 is a smartphone or the like, and includes a display 111 (second monitor) and a control unit 112. The information processing device 110 is connected to the imaging device 10 via a wired or wireless connection. The control unit 112 has the same functions as the control unit 31 and is configured with a second processor. An application program is stored in the information processing device 110, and the control unit 112 executes the application program. As described above, by combining the imaging device 10 and the information processing device 110, an imaging system 115 is constructed that can display image data obtained by the imaging device 10 on the information processing device 110. When transferring images from the imaging device 10, an app on the information processing device 110 can display an effect that makes the image appear as if the film is being developed during the transfer, allowing the user to recognize the transfer process as a development process, thereby providing the user with the experience of shooting with a film camera.

[0109] The control unit 112 either executes a third instruction to make the image data stored in the second storage area 101 displayable on the display 111, or executes a fourth instruction to move the image data stored in the second storage area 101 to the first storage area.

[0110] Specifically, as shown in the flowchart in FIG. 28, when the user selects the third instruction while the information processing device 110 and the imaging device 10 are connected, the imaging device 10 transmits the image data in the first storage area 100 and the second storage area 101 based on the third instruction. The information processing device 110 receives the image data transmitted from the imaging device 10. When reception of the image data is completed, the control unit 112 outputs list image data that lists thumbnail images of the image data based on the image data to the display 111. The list image data is generated based on the image data in the second storage area 101. The list image data is preferably the above-mentioned thumbnail image group 73 (see FIG. 12).

[0111] On the other hand, when the user executes the fourth instruction while the information processing device 110 and the imaging device 10 are connected, the image data transmitted from the imaging device 10 is received, similar to the third instruction. When the reception of the image data is completed, the control unit 112 moves the image data stored in the second storage area 101 to the first storage area 100. This makes it possible to display the image data obtained in film camera mode on the display 111.

[0112] As described above, in film camera mode, in addition to storing a series of image data obtained by shooting in the second storage area 101 of the memory card 42, further display restrictions may be imposed on the image data obtained in film camera mode. Specifically, as shown in FIG. 29, the control unit 31 performs specific processing on the image data obtained in film camera mode, including either an obscuring process or an encryption process on the memory card 42, and stores the image data that has been subjected to the specific processing in the second storage area 101 of the memory card 42 as processed image data information 117. When the image data is stored in the second storage area 101, a management file 120 is created that records information about the image data. Examples of obscuring processes include creating a hidden file or storing the image data as RAW data (the image format of the image data stored in the first storage area 100 is preferably JPEG or the like).

[0113] The management file 120 includes at least one of the following: whether image data has been subjected to an obfuscation process or encryption process, information at the time of shooting, or information for decrypting encrypted images. It is preferable that the specified processed image data information 117 also includes information related to the second directory 103 in which the image data is stored. The management file 120 may be stored in the first storage area 100 in addition to the second storage area 101, but since it is necessary to control the visualization process or encryption process and to keep the file in a visualized state, it is not included in the specified processed image data information 117.

[0114] Similarly to the above, image data obtained by shooting in film camera mode by the imaging device 10 may be transferred to the information processing device 110 and displayed (see FIG. 27). The control unit 112 of the information processing device 110 executes either a fifth instruction for performing a process to visualize the image data that has been made invisible, or a sixth instruction for restoring the encrypted image data, for the image data stored in the second storage area 101.

[0115] Specifically, when the user executes a fifth instruction while the information processing device 110 and the imaging device 10 are connected, the imaging device 10 transmits the image data in the first storage area 100 and the second storage area 101 based on the fifth instruction. The information processing device 110 receives the image data transmitted from the imaging device 10. When reception of the image data is complete, the control unit 112 performs a visualization process on the image data that has been made invisible, and outputs an image to the display 111 based on the image data that has been made visible.

[0116] Furthermore, when the user executes a sixth instruction while the information processing device 110 and the imaging device 10 are connected, the imaging device 10 transmits the image data in the first storage area 100 and the second storage area 101 based on the fifth instruction. The information processing device 110 receives the image data transmitted from the imaging device 10. When reception of the image data is complete, the control unit 112 performs a decryption process on the encrypted image data, and outputs an image to the display 111 based on the decrypted image data.

[0117] To enhance the limitations of the film camera reproduction by the imaging device 10, image data obtained in film camera mode can be recorded not only in the second storage area 101 but also in an invisible state, allowing the user to confirm only that a captured image exists, or allowing the image to be displayed only using a specific device. Various techniques can be incorporated to allow the user to view the image on some device. As one such method, in this embodiment, invisibility processing and encryption processing are performed, and information about the invisibility processing and other factors is recorded and managed in a management file. This allows the film camera mode storage method to be scalable and versatile, allowing it to keep up with user requests and market trends, prevent functions from becoming obsolete, and prevent lost sales opportunities due to specification changes.

[0118] In this embodiment, each process is executed by a computer. The computer may execute these processes by a processor, a program, or a combination thereof.

The processor also has various units or means for executing various processes in the present embodiment. The type of hardware may also be a combination of different types of hardware. When multiple pieces of hardware are configured to execute one or more processes of a certain processor, the multiple pieces of hardware may exist in devices physically separated from each other or in the same device. In any of the embodiments, the order of the processes performed by the processor is not limited to the order described above and may be changed as appropriate. The hardware may be composed of an electric circuit or the like, which is a combination of circuit elements such as semiconductor devices.

[0120] Furthermore, the present embodiment may be implemented by hardware, software, firmware, microcode, or a combination thereof. Software, firmware, and microcode may be configured by a program. A program may also be, for example, a group of program modules, each function of which may be implemented by a processor configured to execute the respective function. The program may be program code or multiple code segments stored on one or more non-transitory computer-readable media (e.g., a recording medium or other storage). The program may be stored in multiple non-transitory computer-readable media that reside in physically separate devices. Program code or a code segment may represent a procedure, a function, a subprogram, a routine, a subroutine, a module, a software package, a class, or any combination of instructions, data structures, or program statements. Program code or a code segment may be connected to another code segment or a hardware circuit by sending or receiving information, data, arguments, parameters, or memory contents.
