Description

  The present invention relates to a photographing apparatus having a rec view function.

  In recent years, portable devices with a photographing function (photographing devices) such as digital cameras have become widespread. Some types of photographing apparatuses are equipped with a rec view function for confirming a recorded image. The REC view function is to display an image captured and recorded for a predetermined time immediately after imaging. The user can check the shooting state by the REC view, which is very convenient.

  However, since the through image cannot be displayed for a predetermined time immediately after shooting for displaying the REC view, the user may want to shorten the REC view display time. On the contrary, there are cases where the user wants to extend the display time of the REC view, for example, when the user wants to check the captured image for a sufficient time.

  Therefore, there is also a photographing device configured to be able to set the display time of the REC view. However, in such a photographing device, an operation for changing the setting of the REC view display time is necessary before the REC view display is performed, and the operation is complicated. As a technique for changing the setting of the REC view display time after the REC view display, there is one disclosed in Patent Document 1. Japanese Patent Application Laid-Open No. 2004-228561 discloses a technique for terminating the REC view display by tilting the camera.

JP 2005-286986 A

  However, in the technique of Patent Document 1, it is necessary to tilt the camera in order to turn off the REC view display, and the operability is not necessarily excellent. In the technique of Patent Document 1, the REC view display can be automatically turned off after a predetermined time. However, if this setting is made, the REC view display cannot be further extended and displayed.

  An object of the present invention is to provide a photographing apparatus that can easily change the display time of the REC view display after photographing.

An imaging device according to the present invention displays an imaging unit and a captured image obtained by the imaging unit in a first period on a display unit, and the display unit in a second period following the first period. The display area of the captured image is gradually reduced, and the display area of the captured image on the display unit is increased or decreased according to the operation during the second period, and the second period is variable. The control unit determines an increase / decrease amount of the display area and an extension / reduction amount of the second period according to an operation amount of the operation during the second period.

  According to the present invention, it is possible to easily change the display time of the REC view display after shooting.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram showing a circuit configuration of the photographing apparatus according to the first embodiment of the present invention.

  The imaging device 10 has an imaging unit 2 configured by an imaging device such as a CCD or a CMOS sensor. An optical image of a subject from an optical system including a photographing lens (not shown) provided on the front surface of the photographing apparatus 10 is formed on an imaging surface of an imaging element constituting the imaging unit 2. The imaging unit 2 is driven and controlled by the signal processing and control unit 11. The signal processing and control unit 11 outputs a driving signal for the image sensor to the image capturing unit 2 and captures an image signal obtained by photoelectric conversion of the optical image by the image sensor.

  The signal processing and control unit 11 performs predetermined signal processing, such as color signal generation processing, matrix conversion processing, and other various digital processing, on the image signal obtained by photoelectric conversion of the image sensor. The signal processing and control unit 11 can output image information, audio information, and the like compressed by performing an encoding process when recording an image signal, an audio signal, and the like.

  The photographing device 10 is also provided with an operation determination unit 3, a clock unit 4, and a touch panel 8. The clock unit 4 generates time information used by the signal processing and control unit 11. The operation determination unit 3 generates an operation signal based on a user operation with respect to various switches (not shown) such as a shooting start / end button and shooting mode setting provided in the shooting device 10 and outputs the operation signal to the signal processing and control unit 11. It has become. The touch panel 8 generates an operation signal based on a user's touch operation and outputs the operation signal to the signal processing and control unit 11. The signal processing and control unit 11 controls each unit based on the operation signal.

  Further, the photographing apparatus 10 is provided with a display control unit 11a and a recording / reproduction control unit 11b. The recording / reproducing control unit 11b is configured to provide the recording unit 9 with the image information and audio information from the signal processing and control unit 11 for recording. The recording unit 9 performs recording and reproduction under the control of the recording / reproduction control unit 11b. As the recording unit 9, for example, a card interface can be adopted, and the recording unit 9 can record image information, audio information, and the like on a recording medium such as a memory card. The recording unit 9 can read out the image information and the audio information recorded on the recording medium and supply them to the signal processing and control unit 11 b. The signal processing and control unit 11 can decode the image information and audio information from the recording unit 9 reproduced by the recording / reproduction control unit 11b to obtain an image signal and audio signal.

  The display control unit 11a gives a captured image from the imaging unit 2 or a reproduction image from the recording / reproduction control unit 11b to the display unit 6 to display these images. Further, the display control unit 11a can display a menu display for operating the photographing apparatus 10 on the display unit 6. The display unit 6 is provided, for example, on the back surface of the main body of the photographing apparatus 10 so that the photographer can visually recognize the display screen of the display unit 6 at the time of photographing. As the display unit 6, an LCD panel or the like can be employed.

  It is also possible to dispose the touch panel 8 on the display screen of the display unit 6. The touch panel 8 generates an operation signal corresponding to the position pointed by the user with a finger. When the touch panel 8 is provided on the display screen of the display unit 6, the user can instruct various command buttons displayed on the display screen of the display unit 6 using the touch panel 8. Thereby, the touch panel 8 can output operation signals corresponding to various command buttons displayed on the display screen of the display unit 6 to the signal processing and control unit 11.

  In the present embodiment, the signal processing and control unit 11 is provided with a REC view control unit 11c. The REC view control unit 11c performs a REC view display in which a captured image that has been captured from the imaging unit 2 and processed by the signal processing and control unit 11 immediately after shooting is displayed on the display screen of the display unit 6 as a REC view image. Do. When ending the REC view display, the REC view control unit 11c gradually deletes the REC view image from the display screen so that the user can recognize that the REC view display is about to end and the REC view display. Before the operation ends, a margin for allowing the user to perform a desired operation is given.

  The REC view control unit 11 determines the time required to completely erase the REC view image from the display screen, that is, the time from the start of the REC view image erasing process to the completion of the erasing process (hereinafter referred to as an erasing process period). Set to a time that is sufficient for user operation. The REC view control unit 11c changes the REC view display during the erasing process period so that the user can recognize that the erasing process period has started. For example, the rec view control unit 11c slides the rec view image when the erasing process period starts.

  2 and 3 are explanatory diagrams for explaining an example of control by the REC view control unit 11c. FIG. 2 shows the state of operations during shooting and REC view display, and FIG. 3 shows a screen display corresponding to FIG. FIG. 2A and FIG. 3A show a state at the time of photographing. FIG. 2A shows a state in which the user 21 holds the photographing device 10 and focuses the flower while adjusting the focus lens 23 to photograph the flower subject 22. FIG. 3A shows a through image displayed at the time of shooting in FIG. On the display screen 7 of the display unit 6, a through image 26 including a flower image 25 as a subject is displayed.

  When shooting is performed, the REC view control unit 11c displays the captured image on the display screen 7 as a REC view image. FIG. 3B shows the REC view display on the display screen 7, and FIG. 2B shows the state of the user confirming the REC view display. In FIG. 3B, the REC view image 28 is displayed over the entire area of the display screen 7. In addition, the REC view control unit 11c displays on the display screen 7 a command button display 29 corresponding to a command for deleting a captured image without recording it.

  When a predetermined time has elapsed since the start of the REC view display, the REC view control unit 11c shifts to an erasing process period. FIG. 3C1 shows the display change in this case, and shows that the REC view image 28 on the display screen 7 moves to the right side of the screen. The right view from the vertical line 29 in FIG. 3C1 is the REC view image 28, and the left side from the vertical line 29 is a display other than the REC view display, for example, a live view display for displaying a through image 30 is performed. Is shown. FIG. 3C2 shows that the subject image 25 ′ currently captured by the imaging unit 2 is displayed as the through image 30. In FIG. 3C1, “Recording” indicating that the REC view image is being recorded in the recording unit 9 is also displayed.

  The REC view control unit 11c slides the REC view image 28. If no user operation occurs during the erasing process period, the REC view control unit 11c deletes the REC view image 28 from the display screen 27 and ends the REC view display. If a user operation occurs during the erasure processing period, the REC view image 28 is stopped from sliding on the display screen so that the REC view image 28 is not erased from the display screen, or the slide direction is reversed to display the REC view image on the display screen. Display the entire area.

  The REC view control unit 11c can accept an operation on the touch panel 8 arranged on the display screen 7 during the erasing process. FIG. 2C shows a state in which the user 21 performs a touch operation on the display screen 7 with the left hand 24. The REC view control unit 11c can also perform processing according to the operation position on the display screen 27 of the user 21. For example, the REC view control unit 11c displays the REC view image 28 display area when the user 21 touches the REC view image 28 on the right side of the vertical line 29 with the vertical line 29 that is the boundary of the REC view display as a boundary. When the user 21 touches the area on the left side of the vertical line 29, the REC view image 28 can be immediately deleted and the REC view display can be terminated. For example, the REC view control unit 11c may determine the slide direction of the REC view image 28 and the through image 30 according to the direction in which the user 21 slides his / her finger on the touch panel 8.

  As described above, the REC view control unit 11c gradually deletes the REC view image from the display screen during the erasing process period, and accepts a user operation for shortening or extending the REC view display time. It is possible to give a margin to the user. In addition, the received user operation can enlarge / reduce the REC view image and extend / decrease the REC view display time.

  Next, the operation of the embodiment configured as described above will be described with reference to the flowchart of FIG.

  When the photographing apparatus 10 is turned on, in step S1 of FIG. 4, the signal processing and control unit 11 determines whether or not the photographing mode is instructed. If the shooting mode is not instructed, the signal processing and control unit 11 determines whether or not the playback mode is instructed in step S2. When the reproduction mode is instructed, the signal processing and control unit 11 displays a list of thumbnails in step S3. When the user selects an image with reference to the thumbnail list, the process proceeds from step S4 to step S5, and the signal processing and control unit 11 reproduces the selected image. If no file is selected, the end of the playback mode is determined in step S6.

  On the other hand, when the shooting mode is instructed, the signal processing and control unit 11 causes the display unit 6 to display the captured image (through image) in live view based on the image signal from the imaging unit 2 in step S11. When the user operates the lens for focusing in this state, the process proceeds from step S12 to step S14, and manual focus is performed. If the lens operation is not performed, automatic focusing is performed in step S13. Next, in step S15, it is determined whether or not a shooting operation has been performed.

  For example, when shooting is instructed by operating a release button or the like, the signal processing and control unit 11 performs shooting in step S16. The signal processing and control unit 11 performs predetermined signal processing on the captured image from the imaging unit 2 to generate a captured image. In step S21, the REC view control unit 11c starts REC view display using the captured image generated by the signal processing and control unit 11. As a result, the captured image is displayed as a REC view image over the entire display screen of the display unit 6.

  The REC view control unit 11 c controls the REC view display using the time information from the clock unit 4. For example, the REC view control unit 11c initializes the REC view display display time t at the REC view display start time. The REC view control unit 11c sets a time from the start of the REC view display to the start of the erasing process (hereinafter referred to as a REC view setting time) to a predetermined setting value or a time based on a user setting operation. FIG. 4 shows an example in which 2 seconds are set as the REC view setting time.

  In step S22, the REC view control unit 11c determines whether or not an operation of the delete command button on the REC view display has been performed before the REC view setting time has elapsed from the start time of the REC view display. When the REC view control unit 11c detects that the delete command button is touched by the operation signal from the touch panel 8, the REC view control unit 11c ends the REC view display in Step S29.

  When the REC view control unit 11c detects that the display time t exceeds the REC view setting time (2 seconds) (Step S23), the REC view control unit 11c shifts the process to Step S24 and starts the REC view display erasure process. For example, the REC view control unit 11c shifts the REC view image in the left-right direction on the display screen of the display unit 6, and displays a live view of another image, for example, a live view image from the imaging unit 2, in a portion other than the REC view image portion. Display. The REC view image is shifted on the display screen at a shift speed corresponding to the erasing process period. The erasing process period is set to a time based on a predetermined set value or a user setting operation by the REC view control unit 11c.

  If the user does not perform any operation such as touching the screen during the erasing process period, the REC view control unit 11c shifts the process from step S25 to step S30 and ends the REC view display. To do. That is, the signal processing and control unit 11 encodes the captured image that has been displayed in REC view into an image file, and then gives the image file to the recording unit 9 for recording.

  When the erasing process period starts, the REC view control unit 11c determines whether or not any operation, for example, a screen touch is performed in Step S26.

  FIG. 5 is a flowchart showing specific processing of touch determination in FIG. In step S41 of FIG. 5, the REC view control unit 11c performs a touch position determination as to which position on the screen the user has touched. Based on an operation signal from the touch panel 8 disposed on the display unit 6, the REC view control unit 11c can determine the touch position by the user.

  Next, the REC view control unit 11c determines which process the user desires based on the time from the start of the erasing process and the touch position. FIG. 6 is a graph for explaining the determination result in the touch determination, with time on the horizontal axis and the position on the screen at the left end of the display of the REC view image on the vertical axis. Note that the vertical axis in FIG. 6 shows the right end of the screen as the maximum value Xr with the left end of the screen as a reference.

  Assuming that the REC view control unit 11c shifts the REC view image to the right during the erasing process period, the position on the screen at the left end of the display of the REC view image changes as shown by a thick line in FIG. That is, the position Xt on the screen at the left end of the display of the REC view image starts to shift to the right side of the screen after 2 seconds, which is the REC view setting time. The position Xt is given by Xt = a · t−Xs, where a is the amount of change per unit time and Xs is the intercept value at time 0 in FIG.

  Therefore, the position information in the horizontal direction of the screen given by the operation signal of the touch panel 8 is converted into 0 to Xr in FIG. 6, and the converted value X is compared with the position Xt, so that the user's touch position is recorded in the REC view image. It is possible to determine whether the image is on the right side, that is, on the REC view image, or on the left side, that is, on an image other than the REC view image.

  When X> a · t−Xs, the REC view control unit 11c determines that the user has touched the right side of the REC view image, that is, the REC view image area (Step S44). On the other hand, when X ≦ a · t−Xs, the user touches a position on the left side of the left end of the REC view image, that is, an image area other than the REC view image, for example, a live view display through-image display. It is determined that it has been performed (step S43).

  In step S27 in FIG. 4, the REC view control unit 11c branches the process depending on whether the user has touched the through image. If the REC view control unit 11c determines that the live view has been touched, the REC view control unit 11c moves the process to Step S30 and ends the REC view display. The signal processing and control unit 11 encodes the captured image that is the basis of the REC view display and creates a file (step S31).

  The REC view control unit 11c branches the process based on whether or not the user has touched the REC view image in Step S28 of FIG. If it is determined that the REC view image is touched, the REC view control unit 11c moves the process to Step S21, initializes the display time t, and then restarts the REC view display. That is, in this case, the REC view image is displayed over the entire display screen.

  Thus, the REC view display is continued until it is determined in step S25 that the REC view image is completely erased. In step S32, the signal processing and control unit 11 determines whether or not a power-off operation has been performed. If the power-off operation has not been performed, the signal processing and control unit 11 repeats the processing from step S1. When the power-off operation is performed, the signal processing and control unit 11 turns off the power (step S33).

  As described above, in the present embodiment, the REC view image displayed immediately after shooting is gradually erased from the display screen after the REC view setting time ends. Since the erasing process period is provided, a time margin for the operation occurs, and the user can easily extend or shorten the REC view display. Further, it is possible to easily instruct continuation of the REC view display by an operation on the REC view display area. Further, by displaying a delete command button on the REC view display, it is also possible to instruct to delete the captured image that is the basis of the REC view. Furthermore, the REC view image on the screen is shifted, the live view image is displayed in the non-display area of the REC view image, and the REC view display is continued depending on which display area is operated by the user. It is possible to easily select whether to display an image. It is also possible to display another image instead of the through image and execute processing corresponding to the other image.

(Second Embodiment)
7 to 14 relate to a second embodiment of the present invention, and FIG. 7 is a perspective view showing an appearance of a photographing apparatus according to the second embodiment. 8 to 12 are explanatory diagrams for explaining the REC view display in the present embodiment.

  The present embodiment is different from the first embodiment only in the display method of the REC view display, and the hardware configuration is the same as that in FIG. The photographing device 10 has a display unit 6 attached to the back surface, and the user can view the display screen 7 of the display unit 6 during photographing or the like.

  FIG. 8 shows the REC view display immediately after shooting, and the REC view image 41 is displayed in substantially the entire area of the display screen 7. A live view display through image 42 is displayed at the lower left corner of the display screen 7. The live view display is to display the captured image being captured by the imaging unit 2 on the display screen.

  In the example of FIG. 8, the REC view control unit 11 c displays the through image 42 in the lower left rectangular area of the display screen 7, and the lower left part of the REC view image is displayed by the display of the through image 42. Chipping occurs.

  In other words, in the present embodiment, the REC view control unit 11c performs live view display in a partial area during REC view display. For example, the REC view control unit 11c displays the through image 42 in, for example, an area of 4% of the area of the display screen 7 so that the REC view image 41 is not difficult to see and the through image 42 can be confirmed. It is supposed to let you.

  In FIG. 8, an area for displaying a through image is provided at the lower left of the display screen 7, but a live view display area may be provided at any position on the display screen 7. For example, rectangular areas at the four corners of the display screen 7 can be used as display areas for live view display.

  Also in the present embodiment, the REC view control unit 11c gradually deletes the REC view image from the display screen after the REC view setting time ends, and the erasing process is completed after the REC view image erasing process starts. The erasing process period is set to a sufficient time that can be operated by the user.

  In this case, as shown in FIG. 9, the REC view control unit 11c gradually enlarges the live view display area for displaying the through image 42 during the erasing process period. FIG. 9 shows an example in which the size of the display area of the live view display is changed step by step to 4%, 9%, 16%,..., 81%, 100% of the area of the display screen 7. When the display area of the live view display reaches 100% of the display screen 7, the REC view image 41 is completely erased from the display screen 7, and the REC view display ends.

  Also in the present embodiment, the REC view control unit 11c can receive a user operation during the erasing process period, and can shorten and extend the REC view display based on the user operation. 10 to 12 show examples of operations for shortening and extending the REC view display.

  FIG. 10 shows a state where the user touches the display screen 7 with the thumb 45 (hereinafter referred to as a touch state). When the REC view control unit 11c detects the touch state of FIG. 10 within the REC view setting time of the REC view display period, the REC view setting time is extended during the period of the touch state. In addition, when the REC view control unit 11c detects the touch state in FIG. 10 during the erasing process period of the REC view display period, the REC view control unit 11c stops the enlargement of the live view display (reduction of the REC view image) during the touch state period.

  FIG. 11 shows a state in which the user has slid the thumb 45 from the center portion on the display screen 7 in an obliquely upward right direction (hereinafter referred to as an upper right slide state). When the REC view control unit 11c detects the upper right slide state in FIG. 11 during the REC view display period, the REC view control unit 11c increases the speed of enlarging the live view display or displays the live view display over the entire display screen 7 to display the REC view. End the display.

  FIG. 12 shows a state in which the user slides the thumb 45 in the diagonally downward left direction from the upper right end portion on the display screen 7 toward the center portion (hereinafter referred to as the lower left slide state). When the REC view control unit 11c detects the lower left slide state in FIG. 12 within the REC view setting time of the REC view display period, the REC view control unit 11c extends the REC view setting time. Also, the REC view control unit 11c reduces the live view display (increases the display area of the REC view image) when detecting the lower left slide state of FIG. 12 during the erasing process period of the REC view display period.

  Note that the operation methods in FIGS. 10 to 12 are examples, and the display process of the REC view display by the operations in FIGS. 10 to 12 may be a process other than that described above.

  Next, the operation of the embodiment configured as described above will be described with reference to the flowcharts of FIGS.

  In the camera control shown in FIG. 13, first, in step S51, it is detected whether or not the shutter button is half-pressed. When detecting that the shutter button is half-pressed, the signal processing and control unit 11 performs automatic focus control in step S52 and performs automatic exposure in step S53.

  In step S54, the signal processing and control unit 11 detects whether or not the shutter button has been released. When the user releases the shutter button, the processes in steps S51 to S53 are repeated. When the shutter button is fully pressed, the signal processing and control unit 11 proceeds from step S55 to step S56 to perform exposure. Next, the signal processing and control unit 11 reads the imaging signal from the imaging unit 2 in step S57.

  Next, the signal processing and control unit 11 performs predetermined signal processing on the read imaging signal to generate a captured image. The signal processing and control unit 11 encodes the generated captured image, and then causes the recording / playback control unit 11b to record the recorded image on the recording unit 9 (step S58). Further, the signal processing and control unit 11 causes the REC view control unit 11c to display the REC view display on the display screen 7 of the display unit 6 (step S59).

  FIG. 14 shows the control of the REC view display in the present embodiment. In step S61, the REC view control unit 11c displays the generated captured image on the display screen 7 of the display unit 6 as a REC view image. Further, in step S62, the REC view control unit 11c displays the live view from the imaging unit 2 as a live display in a partial area of the display screen 7 of the display unit 6. Thereby, for example, as shown in FIG. 8, the live view display through image 42 is displayed at one corner of the display screen 7, and the REC view image 41 is displayed in substantially the entire area of the display screen 7.

  Next, the REC view control unit 11c starts the timer of the clock unit 4 in order to measure the time for controlling the REC view setting time, the erasing process period, and the live view display size change. Next, the REC view control unit 11c determines whether or not the touch panel 8 disposed on the display screen 7 is touched in Step S64.

  Now, for example, it is assumed that the user does not touch the display screen 7 after shooting by fully pressing the shutter button. In this case, the REC view control unit 11c shifts the processing to Step S65, and determines whether or not the REC view setting time (for example, 2 seconds) has been reached. If the display screen 7 is not touched until the REC view setting time elapses from the start of live view display, the process proceeds to step S66, and an erasing process period starts.

  The REC view control unit 11c first initializes the measurement time of the erasing process period. Next, the REC view control unit 11c increases the size of the live view display by one step. As a result, in the REC view display, as shown in FIG. 9, the size of the live view display through image 42 is enlarged to 9% of the display screen 7, and the lower left portion of the REC view image 41 is missing accordingly. Arise.

  In the next step S68, the REC view control unit 11c determines whether or not the live view display is displayed in the maximum size, that is, the entire display screen. If the live view display size has not reached the maximum, the process returns to step S64.

  When the display screen 7 is not touched by the user, the processes of steps S64 to S68 are repeated. In step S65, it is determined whether or not the time until the live view display size is gradually increased has elapsed. For example, as the erasing process period, the user confirms that the REC view display is to be ended, and the REC view display can be extended or shortened before the REC view display is completely ended. Suppose 5 seconds is set. In this case, if the live view display size is switched in nine stages as in the example of FIG. 9, the time for switching the size in each stage is 0.5 in step S65 from the initialization in step S66. What is necessary is just to determine whether second passed. The erasing process period can be changed by the user as in the first embodiment, and can be set in units of 0.5 seconds from 1 second to 20 seconds, for example.

  By repeating the processes of steps S64 to S68, the live view display size becomes maximum, the REC view image 42 is completely erased from the display screen 7, and the live view display ends.

  Next, it is assumed that the user touches the display screen 7 during the live view display period. In this case, the process proceeds from step S64 to step S71, and the measurement time is initialized. Next, the REC view control unit 11c acquires coordinate values on the display screen 7 touched by the user in Step S72, and determines whether or not the touched finger or the like has slid on the display screen 7 in Step S73. . For example, the REC view control unit 11c can detect the presence or absence of a slide from the difference in coordinate values for 0.1 seconds. Furthermore, the REC view control unit 11c determines whether or not the slide amount is equal to or larger than the reference amount in Step S74.

  If the user touches the display screen 7 without sliding, or if the slide amount is smaller than the reference amount, the process proceeds to step S64. As long as the user continues to touch the display screen 7, the process repeats steps S64 and S71 to S74, and the REC view display does not change. When the user lifts his / her finger from the display screen 7, the process proceeds from step S <b> 64 to step S <b> 65, and the time from the initialization in step S <b> 71 has reached the time until the live view display size is gradually expanded. Is determined, and the above-described processing is repeated.

  Here, it is assumed that the user slides on the display screen 7 with a slide amount equal to or larger than the reference amount. In this case, the process proceeds from step S74 to step S75, and the REC view control unit 11c determines whether or not the slide direction corresponds to the direction in which the live view display is enlarged. If the slide direction corresponds to the direction in which the live view display is enlarged, the REC view control unit 11c moves the process to step S76 and enlarges the live view display size by a stage corresponding to the slide amount. For example, assuming that the number of steps is N, N = slide amount / reference amount. By setting the reference amount to the actual size of one stage in FIG. 9, the live view display size can be enlarged only by the stage corresponding to the amount of movement of the finger.

  If the slide direction corresponds to the direction in which the live view display is reduced, the REC view control unit 11c moves the process to step S77, and reduces the live view display size by a stage corresponding to the slide amount. For example, assuming that the number of steps is N, N = slide amount / reference amount. By setting the reference amount to the actual size in one stage of FIG. 9, the live view display size can be reduced only by the stage corresponding to the amount of movement of the finger.

  As described above, in this embodiment, the same effect as that of the first embodiment can be obtained, and the live view display size can be changed according to an operation of touching or sliding the display screen. It is.

  In each of the above-described embodiments, an example in which REC view display is performed on the display unit provided in the body of the photographic device has been described. However, REC view display is performed on a viewfinder that is an external part of the photographic device. Obviously it may be.
