[0005] [Patent Document 1] Patent No. 4253086 [Patent Document 2] Japanese Patent Application Laid-Open No. 2003-78806 [Patent Document 3] Patent No. 5057135 Summary of the Invention [Problem to be solved by the invention]
[0006] An object of the present invention is to provide an imaging device, method, and program that allows users to experience analog photography operations with the film unloaded from a film camera. [Means for solving the problem]
[0007] The present invention is an imaging device having a processor, which acquires first information regarding the insertion and removal of a recording medium that records imaging data of the imaging device, and restricts a first shooting mode related to the functions of the imaging device based on the first information.
[0008] When the first shooting mode is activated, the processor preferably performs first control, which is control of either execution of the first shooting mode or control of restriction of the first shooting mode, based on the first information. When the first shooting mode is executed, the processor preferably outputs error information based on the first information. After outputting the error information, the processor preferably performs second control, which is control of either continuation of the first shooting mode or control of the first shooting mode, based on the first information.
[0009] When the imaging device is powered off and then powered back on while the first shooting mode is being executed, it is preferable that the processor performs a third control, which is either control to continue the first shooting mode or control to restrict the first shooting mode, based on the first information.
[0010] When the first photographing mode is ended, the processor preferably performs initialization related to the first photographing mode. The initialization is preferably a process of not using the first setting value set in the first photographing mode as the second setting value set in the second photographing, which is the next photographing in the first photographing mode. When the first photographing mode is ended, the processor preferably executes the second photographing mode, which is a photographing mode different from the first photographing mode.
[0011] The first shooting mode is preferably a shooting mode in which the number of shots is limited. The first shooting mode is preferably a shooting mode in which the image format is limited. The first shooting mode is preferably a shooting mode in which the processor is restricted from outputting a live view to the monitor. The first shooting mode is preferably a shooting mode in which the series of image data obtained by shooting in the first shooting mode is restricted from being saved in a format other than a single unit format. The first information is preferably information including the insertion / removal status of a recording medium.
[0012] Preferably, the processor executes the first photographing mode when the first information indicates an inserted state of the recording medium, and restricts the first photographing mode when the first information indicates an removed state of the recording medium. Preferably, the processor determines whether or not a first attribute has been assigned to the recording medium by executing the first photographing mode, and if the first attribute is present, continues the first photographing mode, and if the first attribute is not present, restricts the first photographing mode.
[0013] It is preferable that the processor determines whether or not a first attribute has been assigned to the recording medium by executing the first shooting mode, and if the first attribute is present and the second attribute assigned to the data on the recording medium in association with the history record has not been changed from the outside, continues the first shooting mode, and if the first attribute is present and the second attribute assigned to the data on the recording medium in association with the history record has been changed from the outside, restricts the first shooting mode.
[0014] When the power of the imaging device is turned off and then turned back on, it is preferable that the processor determines whether or not a first attribute has been assigned to the recording medium by executing the first shooting mode, and if the first attribute is present, continues the first shooting mode, and if the first attribute is not present, restricts the first shooting mode.
[0015] When the imaging device is turned off and then turned back on, the processor preferably determines whether or not a first attribute has been assigned to the recording medium by executing the first shooting mode, and if the first attribute is present and the second attribute assigned to the data on the recording medium in association with the history record has not been changed externally, continues the first shooting mode, and if the first attribute is present and the second attribute assigned to the data on the recording medium in association with the history record has been changed externally, restricts the first shooting mode.
[0016] The present invention is an imaging device having a processor, which, when a recording medium is inserted, acquires second information regarding the attributes of the recording medium and restricts a first shooting mode regarding the functions of the imaging device based on the second information.
[0017] The attributes preferably include either a first attribute that is assigned to the recording medium by executing the first shooting mode, or a second attribute that is assigned to the data on the recording medium in association with the history record.
[0018] In the imaging method of the present invention, a processor of an imaging device acquires first information related to the insertion or removal of a recording medium that records imaging data of the imaging device, and restricts a first shooting mode related to the functions of the imaging device based on the first information.
[0019] The imaging program of the present invention is a program for causing a processor of an imaging device to execute a process of acquiring first information regarding the insertion and removal of a recording medium that records imaging data of the imaging device, and a process of restricting a first shooting mode related to the functions of the imaging device based on the first information.

[0022] 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.
[0023] 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.
[0024] 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.
[0025] 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.
[0026] 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.
[0027] 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.
[0028] The rear surface of the camera body 11 is provided with a display 22 (monitor section), 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 imaging element 21 is displayed on the display 22 in real time.
[0029] 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.
[0030] 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.
[0031] 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.
[0032] 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).
[0033] 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.
[0034] 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 processor that controls each part of the imaging device 10.
[0035] 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.
[0036] 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.
[0037] 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.
[0038] 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.
[0039] 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.
[0040] 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.
[0041] 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.
[0042] 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).
[0043] 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.
[0044] 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.
[0045] "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").
[0046] 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.
[0047] 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.
[0048] 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.
[0049] 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.
[0050] 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.
[0051] 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 of the shot to the display 22.
[0052] 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.
[0053] 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.
[0054] 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.
[0055] 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.
[0056] 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.
[0057] In the film camera mode, when the number of shots reaches a predetermined number, it is preferable that the control unit 31 disables the shooting operation using the release switch 15 and the unlocking of the shooting operation using the lever 17. In addition, in the film camera mode, when the number of shots reaches a predetermined number, it is preferable that the control unit 31 saves a series of image data obtained by shooting as a single unit in the memory card 42. In addition, 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.
[0058] 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.
[0059] 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.
[0060] 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 restriction, restriction on output to the live view display 22, restriction on saving a series of image data obtained by shooting in the film camera mode in a format other than the format of a single unit, restriction on the number of shots, and restriction on a second shooting operation following a first shooting operation.
[0061] 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.
[0062] 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).
[0063] 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.
[0064] 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.
[0065] Specifically, when the film camera mode is activated, the control unit 31 preferably performs first control, which is control to either execute the film camera mode or restrict the film camera mode, based on the first information. Activation of the film camera mode is performed by touching the sub-display 24, as described above. As shown in (A) of FIG. 14, when the first information indicates that the memory card 42 is inserted (see FIG. 15), the control unit 31 executes the film camera mode. 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. Activation of the film camera mode includes not only selecting the film camera mode in the imaging device 10 that is already activated, but also setting the film camera mode when the imaging device 10 is activated.
[0066] 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.
[0067] 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.
[0068] 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.
[0069] 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.
[0070] The first attribute is created as a management file in the memory card 42 when the film camera mode is first started. 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.
[0071] 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.
[0072] 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.
[0073] 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.
[0074] 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.
[0075] Furthermore, when the film camera mode is executed, if the imaging device 10 is powered off and then powered on again, 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. Note that turning the power of the imaging device 10 on and off includes turning the power on and off by operating the power button of the imaging device 10, as well as by inserting and removing a battery inserted in the imaging device 10.
[0076] 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.
[0077] 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)).
[0078] 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)).
[0079] 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.
[0080] 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.
[0081] 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 preferably involves not using 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. The setting values used in the previous film camera mode are not carried over (reset) to the next film camera mode through initialization. Here, examples of the first setting value or the second setting value include the number of shots that can be taken, the film simulation pattern, the exposure amount set with the mode dial 14, and the aperture value. 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.
[0082] 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.
[0083] 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.
[0084] 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.
[0085] 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.
[0086] The imaging program of the present invention is a program for causing the control unit 31 to execute a process of acquiring first information regarding the insertion or removal of the memory card 42 that records imaging data of the imaging device 10, and a process of restricting the film camera mode based on the first information.
