Description

  The present invention relates to a display device capable of displaying an image by reversing the left and right.

  For example, when trying to imitate while watching a movie of a dance scene, it is difficult to imitate the original correct movement because it is reversed left and right. For this reason, it is convenient for dance practice or the like by performing playback in a playback mode in which the left and right sides are reversed according to the settings of the playback device during playback, so that the player looks at the mirror.

  In addition, there is a device that records the image by reversing the left and right during shooting. In some cases, these are combined, and a moving image that is reversed left and right during recording can be reversed again during reproduction and viewed as a normal image.

As a result, there are the following four states.
(1) Normal recording + normal playback → normal image
(2) Normal recording + left / right reverse playback → reverse image
(3) Left / right reverse recording + normal playback → reverse image
(4) Left / right reverse recording + left / right reverse playback → normal image

  Also, when displaying the video you are shooting or playing on the camcorder's LCD panel horizontally reversed, the information display using characters and icons, the operation display, etc. must be reversed horizontally. Display without any problem (for example, Patent Documents 1 and 2).

However, the above-described conventional example has the following problems because it can be switched between right / left reversal during recording and reversal during reproduction.
That is, as described above, there are four states in the reproduced image, and it is difficult to grasp the state of the reproduced image that the user is currently viewing. In addition, it is difficult to grasp the state when the left / right reversal during playback is performed, and it is difficult for the user to determine whether the reversal function during playback should be turned on.
The present invention has been made in view of the above-described problems, and it is an object of the present invention to make it easy for a user to easily switch between recording and playback while recognizing a horizontally reversed state.

  The display control apparatus according to the present invention includes a reproduction unit that reproduces an image, an acquisition unit that acquires information about whether the image reproduced by the reproduction unit is inverted and recorded, and an image reproduced by the reproduction unit. The information acquired by the acquisition means, the switching processing means for switching whether to perform the reverse processing in the reverse processing means, and the display item indicating whether the image is reversed and displayed. And a control means for controlling to display on the display unit together with the image reproduced by the reproduction means in a different display form depending on the combination of whether or not the reversal processing is switched by the switching means. It is characterized by that.

  According to the present invention, depending on whether the image being displayed is an image that has been inverted and recorded, and whether the recorded image has been subjected to inversion processing and is being reproduced and displayed, It is possible to notify the user of the status of the displayed playback image so that the user can easily grasp it.

Hereinafter, the present invention will be described in detail based on preferred and exemplary embodiments with reference to the drawings.
1A to 1C are external views of a digital camera 100 as an embodiment of the display control apparatus of the present invention.

  The digital camera 100 includes an imaging unit 12 (a portion illustrated in the drawing is a photographic lens unit included in the imaging unit) facing a subject in a main body 110. The monitor unit 120 includes a display unit 14. The monitor unit 120 is connected to the main body unit 110 via a hinge unit, rotates about the shaft 101 and the shaft 102, and positions relative to the main body unit 110 as shown in FIGS. 1 (a) to 1 (c). Can be changed. An origin 130 indicates the origin coordinates of the display unit 14 and is a point where the X coordinate = 0 and the Y coordinate = 0. It is assumed that the origin 130 is defined as the upper left of the display unit 14.

FIG. 1A shows a positional relationship in which the monitor unit 120 is closed with respect to the main body so that the display surface of the display unit 14 is exposed. This position is referred to as a closed position.
FIG. 1B shows a state in which the monitor unit 120 is rotated about 90 degrees around the shaft 101 from the closed position in FIG. is there. This position is referred to as an open position. In the open position, as illustrated, the display surface of the display unit 14 and the imaging surface of the imaging unit 12 face in opposite directions. That is, the display unit 14 is used as a rear monitor.

  FIG. 1C shows a state in which the monitor unit 120 is rotated about 180 degrees around the axis 102 parallel to the horizontal direction of the display unit 14 from the open position in FIG. This position is referred to as a facing position. At the facing position, as shown in the figure, the display surface of the display unit 14 and the imaging surface of the imaging unit 12 face the same direction.

  That is, the display surface of the display unit 14 can be viewed from the subject side, and is used as a face-to-face monitor. At the facing position, as shown in the figure, the upper left origin 130 of the display unit 14 is located at the lower right when viewed from the user, and the apparent positional relationship is inverted vertically and horizontally from the open position. Therefore, in order to show the same video to the user at the open position and the facing position, it is necessary to display the image displayed at the open position by performing upside down / left / right inversion processing or 180 ° rotation processing. In addition, since the same result image is displayed regardless of whether the up / down / left / right inversion processing or the 180 ° rotation processing is performed, what is simply referred to as “up / down / left / right inversion processing” is replaced with the 180 ° rotation processing. It may be acceptable.

  FIG. 2 shows a configuration block diagram of the digital camera 100. The following components are connected to the control unit 10 (CPU). Image compression / decompression unit 11, imaging unit 12, image processing unit 13, display unit 14, operation unit 15, ROM 16, RAM 17, removable recording medium interface (I / F) (18), external interface (I / F) ( 20) Monitor position detection unit 21. The control unit and each component unit can exchange data with each other.

  The control unit 10 is a system control unit that controls the entire system of the digital camera 100. The control unit 10 develops and executes the program recorded in the ROM 16 on the RAM 17 to control each component, and executes a flowchart described later. The ROM 16 is a nonvolatile recording medium and stores a program executed by the control unit 10. The RAM 17 is a volatile recording medium used as a work memory for the control unit 10. The RAM 17 performs image data captured by the image capturing unit 12 and image processed by the image processing unit 13 or image data read from the removable recording medium 19, and the image compression / decompression unit 11 performs image data compression or decompression processing. Used to apply. The RAM 17 is also used as a VRAM that is temporarily stored for display on the display unit 14. Furthermore, it is also used as a RAM for temporarily storing attribute information to be recorded in association with the captured image.

  The digital camera 100 can be loaded with a recording medium for recording image data. For this purpose, an interface of a detachable recording medium I / F (18) is provided. The removable recording medium I / F (18) is a slot into which a removable recording medium such as a memory card can be inserted. FIG. 1 illustrates an example in which a detachable recording medium (19) is attached to a detachable recording medium I / F (18). The digital camera 100 has been described with a configuration in which image data is recorded on a detachable recording medium. However, a configuration in which detachment is impossible and image data is recorded in a memory built in the digital camera 100 is also conceivable.

  The image processing unit 13 performs predetermined pixel interpolation, resizing processing, color conversion processing, rotation processing, left / right conversion processing, up / down conversion processing, and up / down / left / right conversion processing on the image data captured by the imaging unit 12. The image processing unit 13 performs predetermined calculation processing using the captured image data, and the control unit 10 performs various controls (exposure control, auto white balance) related to imaging by the imaging unit 12 based on the obtained calculation result. Control).

The image compression / decompression unit 11 performs a process of compressing the image data processed by the image processing unit 13 and a process of expanding the image data read from the removable recording medium 19.
The imaging unit 12 includes a photographic lens (including a zoom lens and a focus lens) and an imaging element, images a subject under the control of the control unit 10, and acquires image data such as a still image and moving image data.

The display unit 14 is a display for displaying various setting states, images picked up by the image pickup unit 12, images read out from a removable recording medium and reproduced based on the control of the control unit 10. In this embodiment, it is configured as a vari-angle liquid crystal monitor.
The operation unit 15 includes operations from the user, including a power switch for supplying power to the digital camera 100, a shooting start button, a mode switching button that can be switched to a camera mode (shooting mode) and a playback mode, a touch panel, and the like. It is an operation unit to accept. The touch panel is an operation member configured integrally with the display unit 14.
The external I / F (20) is an interface with an external device, and is a communication interface that transmits or receives images and other data to and from the external device wirelessly or by wire, or a video output interface that outputs a video signal to the external device. is there.

  The monitor position detection unit 21 detects which positional relationship the monitor unit 120 has relative to the main body unit 110. It can be configured by a switch or a hall element provided in the hinge portion, and can detect whether the monitor portion is in the above-mentioned closed position, open position, or facing position.

FIGS. 3A and 3B show examples of reproduction display on the digital camera 100 and a television 301 as an example of an external device.
FIG. 3A is a display example when the monitor unit 120 is in the open position. An image read from the detachable recording medium 19 is reproduced, and a reproduced image 302 that has not been subjected to rotation processing or inversion processing is displayed on the display unit 14. Also on the external device 301 connected via the external I / F (20), the same image as that displayed on the display unit 14 is displayed as it is on the display unit 14 without being subjected to rotation processing or inversion processing. .

  FIG. 3B is a display example when the monitor unit 120 is set to the facing position. An image read from the detachable recording medium 19 and subjected to up / down / left / right reversal processing (reproduced image 303) is displayed on the display unit. Therefore, when displaying based on the same image, the reproduced image 302 displayed in FIG. 3A and the reproduced image 303 displayed in FIG. 3B have an upside-down relationship with respect to the origin 130.

  However, as illustrated, when viewed from the user, the reproduced image 302 and the reproduced image 303 appear in the same direction. In this way, even when the direction of viewing the monitor unit 120 is changed by rotating the monitor unit 120, the image can be viewed in the same direction as viewed from the user. Unlike the reproduced image 303 in which the same source image displayed on the display unit 14 is inverted vertically and horizontally, the external device 301 connected via the external I / F (20) is rotated and inverted. It is displayed on the display unit 14 as it is without being processed.

  In the digital camera 100, the reverse recording mode can be set. When the reverse recording mode is set, the captured image is reversed left and right and recorded on the removable recording medium 19. When an image recorded in the reverse recording mode is reproduced, an image that is a mirror image of the actually photographed subject is reproduced. The reverse recording mode is useful when shooting dance choreography for educational materials. Even if the choreographer dances as usual during the shooting, the mirror image is played back regardless of the playback device. You can practice in a relationship. It is also convenient when shooting sports forms such as golf swings.

  FIGS. 4A and 4B show display examples at the time of shooting when the reverse recording mode is turned off (live view display during shooting standby and live view display during shooting recording). FIG. 4A is a display example when the subject 401 is photographed with the monitor unit 120 in the open position. The captured image is displayed on the display unit 14 as it is without being inverted or rotated, and a live view image 410 is displayed. The left-right relationship between the subject 401 and the live view image 410 looks in the same direction as viewed from the photographer viewing the display unit 14 from the back side opposite to the imaging unit 12. On the television 301 which is an external device, the same video as the image recorded on the removable recording medium 19 is output and displayed.

  FIG. 4B is a display example when the subject 401 is photographed with the monitor unit 120 as the facing position. It is assumed that the positional relationship between the digital camera 100 and the subject 401 is the same as in the case of FIG. 4A except that the overhead view position is different, and the same video is captured. If the captured image is displayed upside down and horizontally reversed as in the case of playback, it is a normal image, but when viewed from the subject 401, it moves in the direction opposite to that of the subject and fits within the shooting range as intended. It is difficult to adjust the composition, such as taking or posing.

  Therefore, when the monitor unit 120 is at the facing position, the image is displayed as a mirror image (mirror display) as shown in FIG. The live view image 411 has the left-right relationship in the image reversed as compared to the live view image 410 displayed at the open position when viewed from the user. Since the live view image 411 displayed in this manner moves in the same direction as the user as seen from the mirror when viewed from the subject, it is easy to perform composition adjustment such that the user fits in the shooting range as intended and takes a pose. Become.

  In order to display the image as a mirror image, the photographed image is inverted upside down. The left and right are not reversed. This is because the monitor unit 120 viewed from the user is up and down and left and right opposite to the open position. Note that, as the video displayed on the television 301, the video output to the external device and the image recorded on the detachable recording medium 19 remain normal images, and the mirror image is displayed on the display unit 14 at the facing position. It is only an image for display.

  FIGS. 5A and 5C show display examples at the time of shooting (live view display during shooting standby and live view display during shooting recording) when the reverse recording mode is turned on. FIG. 5B shows a display example when the present application is not carried out when the reverse recording mode is turned on.

  FIG. 5A is a display example when the subject 401 is photographed with the reverse recording mode turned on and the monitor unit 120 set to the open position. Since the reverse recording is on, the captured image is reversed left and right and displayed on the display unit 14, and a live view image 501 that is a mirror image is displayed. The left-right relationship between the subject 401 and the live view image 501 looks in the opposite direction when viewed from the photographer viewing the display unit 14 from the back side opposite to the imaging unit 12.

  Thereby, it can be recognized that the reverse recording mode is on and the captured image is reversed left and right and recorded as a mirror image. In addition, a mode icon 502 indicating that the reverse recording mode is in progress is displayed superimposed on the live view image 501. On the television 301 as an external device, the same mirror image as the image recorded on the removable recording medium 19 is output and displayed.

  Normally, when the monitor unit 120 is rotated from the open position to the facing position, the image displayed so far is mirror-inverted and displayed as a mirror image. However, when the reverse recording mode is turned on, when the monitor 120 is rotated from the open position to the facing position and the video that has been displayed so far is displayed with mirror inversion, FIG. Is displayed.

  The live view image 503 is a mirror image of the live view image 501 displayed as a mirror image. As processing, the live view image 501 is inverted only up and down. As a result, a normal image is obtained by inverting the captured image vertically and horizontally. Even when the subject sees such a live view image 503, it is difficult to fit within the shooting range or to pose because a video of the movement in the direction opposite to the left and right is seen.

  Furthermore, since a normal image is visible, it is difficult to determine whether or not the reverse recording mode is on only by looking at the live view image 503. That is, the display is not particularly advantageous when viewed from the subject. Therefore, in the present invention, when the facing position is reached in the reverse recording mode, the display as shown in FIG.

  FIG. 5C is a display example in the case where the reverse recording mode is turned on and the subject 401 is photographed with the monitor unit 120 as the facing position. It is assumed that the positional relationship between the digital camera 100 and the subject 401 is the same as in the case of FIG. When the reverse recording mode is on and the monitor unit 120 is at the facing position, the image is displayed as a mirror image as shown in FIG.

  The live view image 504 is a mirror image obtained by rotating the live view image 501 displayed as a mirror image by 180 degrees. The processing is an image obtained by inverting the captured image only up and down. The live view image 504 has the same left-right relationship in the image as compared to the live view image 501 displayed at the open position when viewed from the user.

  When the subject sees such a live view image 504, an image of a movement in the same direction as his / her right and left can be seen, so that it is easy to fit within the shooting range and pose. Although it is difficult to determine whether or not the reverse recording mode is on only by looking at the live view image 504, the reverse recording mode is turned on when the mode icon 502 is displayed. Recognize.

  It should be noted that the mode icon 502 is inverted up and down and left and right from the case of FIG. 5A, and the display position is displayed at a point-symmetrical position with the center of the display unit 14 as an axis. On the television 301 which is an external device, the same mirror image as the image recorded on the detachable recording medium 19 (an image obtained by horizontally inverting the captured image) is output and displayed.

  FIG. 6 is a flowchart of the shooting mode process. A process for realizing the above-described display will be described. The processing in FIG. 6 is realized by developing a program recorded in the ROM 16 in the RAM 17 and executing it by the control unit 10. When the digital camera 100 is activated in the shooting mode, the process of FIG. 6 is started.

  In S601, the control unit 10 refers to the mode information recorded in the ROM 16, and determines whether or not the reverse recording mode is currently on. If it is off, the process proceeds to S602, and if it is on, the process proceeds to S605.

In S <b> 602, the control unit 10 determines whether the monitor unit 120 is at the facing position based on the output of the monitor position detection unit 21. If it is not the facing position, that is, if it is the closed position or the open position, the process proceeds to S603, and if it is the facing position, the process proceeds to S604.
In step S <b> 603, the control unit 10 displays the through image (live view image) captured by the imaging unit 12 on the display unit 14 in the same orientation without performing inversion / rotation processing. As a result, the display at the open position as shown in FIG.

  In step S <b> 604, the control unit 10 displays the through image (live view image) captured by the imaging unit 12 upside down by the image processing unit 13 on the display unit 14. As a result, a mirror image is displayed at the facing position as shown in FIG.

In S <b> 605, the control unit 10 determines whether the monitor unit 120 is at the facing position based on the output of the monitor position detection unit 21. If it is not the facing position, that is, if it is the closed position or the open position, the process proceeds to S606, and if it is the facing position, the process proceeds to S607.
In step S <b> 606, the control unit 10 displays the through image (live view image) captured by the imaging unit 12 on the display unit 14 by performing left / right reversal processing using the image processing unit 13. Further, a mode icon 502 indicating that the reverse recording mode is on is displayed superimposed on the live view image. As a result, the mirror image is displayed at the open position as shown in FIG.

  In step S <b> 607, the control unit 10 displays the through image (live view image) captured by the imaging unit 12 upside down by the image processing unit 13 and displays it on the display unit 14. In addition, a mode icon 502 indicating that the reverse recording mode is on is superimposed on the live view image and displayed upside down. As a result, a mirror image is displayed at the facing position as shown in FIG.

  In step S <b> 608, the control unit 10 determines whether a reverse recording mode on / off switching operation has been performed by the user. The reverse recording mode can be turned on / off in a state where the switching screen is displayed by selecting the reverse recording mode on / off switching item included in the setting menu, and the user can arbitrarily set the on / off. it can. If the reverse recording mode ON / OFF switching operation is performed by the user, the process proceeds to S609, and if not, the process proceeds to S610.

In step S609, the control unit 10 switches on / off of the reverse recording mode set according to the user operation, and records mode information indicating the state of the switching result in the ROM 16.
In S610, the control unit 10 determines whether or not the shooting start button of the operation unit 15 is pressed and an instruction to start shooting a moving image is given. If it is determined that the start of video shooting has been instructed, the process proceeds to S611, and if not, the process proceeds to S616.

In S611, the control unit 10 refers to the mode information recorded in the ROM 16, and determines whether the reverse recording mode is on or off. If it is off, the process proceeds to S612, and if it is on, the process proceeds to S613.
In S612, the control unit 10 records the moving image captured by the imaging unit 12 on the removable recording medium 19 without changing the orientation.

In step S <b> 613, the control unit 10 performs left-right reversal processing on the moving image captured by the imaging unit 12 and then records it on the removable recording medium 19. A mirror image of the moving image is recorded with respect to the captured image.
In S614, the control unit 10 determines whether or not the shooting start button of the operation unit 15 is pressed again and a shooting stop instruction is issued. If there is an instruction to stop shooting, the process proceeds to S615. If not, the process returns to S611 to continue shooting.

  In S615, the control unit 10 performs a stop process. That is, various information at the time of shooting is attached to the moving image file storing the moving image recorded on the removable recording medium 19 (recorded in association with the moving image), and the file closing process is performed. At this time, attribute information (left / right reverse flag) indicating whether or not the moving image is recorded with the reverse recording mode turned on is also recorded. The left / right inversion flag is recorded in header information of a moving image file, an associated management file, or a management file generated in the same folder as the moving image file.

  In S616, the control unit 10 determines whether or not there is an end event for ending the shooting mode process. The end event occurs when an operation to turn off the power, an operation to shift to another operation mode such as a reproduction mode, or the detection of the opening of a storage slot of a recording medium such as a memory card is opened. If there is no end event, the process returns to S601 to continue the shooting mode process, and if there is an end event, the process of FIG.

  In the above-described processing, an example in which a moving image is captured in the reverse recording mode has been described. However, a still image can also be captured in the reverse recording mode. A still image captured in the reverse imaging mode is recorded as an image file of a mirror image obtained by reversing the captured image.

  Further, although the example in which the mode icon 502 is displayed together with the live view image when the reverse recording mode is on has been described, the mode icon 502 may not be displayed. By not displaying the mode icon 502, it is possible to prevent a portion of the live view image that is hidden behind the mode icon 502 from being generated and display the live view image with high visibility.

  In addition, in the case of S607, that is, as shown in FIG. 5C, it can be seen that the reverse recording mode is turned on only with the live view image only when the reverse recording mode is turned on and shooting is performed at the facing position. Since there is no mode icon 502, the mode icon 502 may be displayed. Even when the reverse recording mode is on, the mode icon 502 is not displayed in the closed position and the open position (in the case of S606). Accordingly, the live view image can be displayed with high visibility without hiding a part of the live view image.

  Even if the mode icon 502 is not displayed, since the live view image is highlighted, it can be identified that the reversed recording mode is on. In addition, when the reverse recording mode is on, the mode icon 502 is displayed regardless of the position of the monitor unit 120, but it is also conceivable that the display form is different depending on whether it is the facing position or not. For example, it is conceivable to perform at least one of display such as displaying larger in the case of the facing position, displaying in a conspicuous color (for example, red), and blinking.

  When the position is not the face-to-face position, the mode icon 502 is displayed smaller than the face-to-face position, displayed in a non-obtrusive color (for example, white), or lit. This also makes it possible for the user to reliably recognize that the reverse recording mode is on when the facing position is particularly difficult to notice that the reverse recording mode is on.

  Further, it is possible to prevent the live view display from being hindered at other positions as much as possible. Note that the mode icon 502 does not have to have the form as described above, and may be any information display different from the live view display so that the user can identify that the recording mode is the reverse recording mode. For example, a character string such as “in reverse recording mode” may be displayed.

  In addition, although the example which the monitor part 120 can rotate centering on the axis | shaft 102 was demonstrated, the vari-angle mechanism is not restricted to this, Opposite to the facing position where a live view image faces a photographing direction (subject side). The present invention can be applied as long as it can be moved to a facing position. For example, a configuration in which the monitor unit 120 can be rotated around an axis parallel to the display surface of the display unit 14 and perpendicular to the axis 102, that is, an axis parallel to the vertical direction of the display unit 14 is also applicable. In this case, in any of the above-described S604, S606, and S607, the through image is not reversed upside down but is reversed left and right to obtain a mirror image display. Further, when the playback mode is changed from the open position to the facing position, the playback image is displayed without being reversed or rotated and without changing the orientation.

  As described above, according to the present invention, at the facing position where the display unit that displays the live view faces the shooting direction (subject side), the mirror image display is performed regardless of whether the mirror image is displayed at a position that is not the facing position. do. Further, at the facing position, the captured image is displayed as a mirror image regardless of whether or not the captured image is recorded as a mirror image. This facilitates adjustment of the composition of the image as viewed from the subject side. In this case, if the operation mode for recording with a mirror image is set, the information indicating that is displayed. Therefore, even if the mirror image display is performed at the facing position, it is identified whether the operation mode is for recording with a mirror image. Can be made.

In addition, when it is not the facing position, if the captured image is recorded as a mirror image, the display is also performed as a mirror image. In this way, even if there is no notification with an icon or the like, the user can be identified that the operation mode is to record with a mirror image.
Although the control in the above-described shooting mode processing has been described as being performed by the control unit 10, one hardware may be performed as described above, and a plurality of hardwares share the processing so that the entire apparatus can be controlled. Control may be performed.

  Further, the case where the control corresponding to the shooting mode process is applied to the digital camera 100 has been described as an example. However, this is not limited to this example, and any display control apparatus including a display unit whose position can be moved is used. Applicable. That is, the present invention can be applied to personal computers, PDAs, mobile phone terminals, music players, game machines, electronic book readers, and the like.

  A method for reproducing the image recorded by the above-described processing of FIG. 6 in the display control apparatus of the present embodiment will be described. Note that the processing described below is processing at the time of reproduction of a recorded image, and thus can be performed not only by the digital camera 100 but also by other display control devices.

  As in the above-described shooting mode processing, the image to be reproduced may be an image (reversed image) recorded by reversing the left and right at the time of shooting. In the present embodiment, it is also possible to perform reproduction by performing a process of inverting left and right during reproduction. As a result, even when a normal image recorded without left-right reversal is reproduced, it can be displayed as a mirror image (reversed image) by left-right reversal processing during reproduction. Therefore, it is convenient for dance practice.

However, the following four states occur due to the fact that recording can be performed by reversing the left and right at the time of shooting, and that the recording can be performed by reversing the left and right during reproduction.
(1) Normal recording + normal playback → normal image
(2) Normal recording + left / right reverse playback → reverse image
(3) Left / right reverse recording + normal playback → reverse image
(4) Left / right reverse recording + left / right reverse playback → normal image

  If there are such four states, it may be difficult to grasp the state of the reproduced image that the user is currently viewing. In addition, it is difficult to grasp the state when the left / right reversal during playback is performed, and it is difficult for the user to determine whether the reversal function during playback should be turned on. In view of this, in the image reproduction processing of the present embodiment, the display is performed so that the user can easily grasp the left / right inversion state of recording / reproduction and can easily perform switching.

FIG. 7A shows a display example in the case where a moving image is shot and recorded with the reverse recording mode turned off. In addition to the live view, a shooting mode icon, a battery capacity, a shooting elapsed time, and a remaining shooting time that are omitted in FIG. 5 are also illustrated.
In FIG. 7A, since the reverse recording mode is off, the character “ABC” printed on the shirt of the subject person is shown as a normal image.
FIG. 7B shows a display example when a moving image is shot and recorded with the reverse recording mode turned on. In this case, since a mirror image is recorded, the character “ABC” of the shirt of the person who is the subject is shown in a state where it is horizontally reversed. An operation for reproducing the image thus captured will be described.

When the operation mode of the digital camera 100 is switched to the playback mode, an index screen on which thumbnail images of a plurality of scenes (cuts) as shown in FIG.
When one of the thumbnails is tapped (an operation for touching and releasing the touch panel integrated with the display unit 14), the moving image indicated by the tapped thumbnail is read from the removable recording medium 19 and reproduced. The moving image being reproduced can be reversed horizontally according to the user's operation. The reverse icon is used to indicate whether the video being played is a video recorded in the reverse recording mode and whether the video is being played back and forth (reverse playback). To display.

FIG. 9 is an example of a screen display during moving image reproduction.
There are icons, counters, date displays, etc. that indicate playback operations. Display items on the upper left of the screen are reverse icons 901 to 904. The inversion icons 901 to 904 indicate whether or not the moving image being reproduced is a moving image recorded in the reverse recording mode, and whether or not the reverse reproduction is being performed, and the on / off switching operation of the reverse reproduction is performed. The touch icon to accept. In the present embodiment, an icon having an alphabet letter “R” as a motif (material) is used. Other motifs may be used as long as they are asymmetrical motifs such as “R” and can distinguish between normal and inverted images.

  FIG. 10A shows a correspondence diagram of display forms of the inversion icons 901 to 904 depending on whether or not recording is performed in the inversion recording mode and whether or not inversion reproduction is performed. It is assumed that information corresponding to this correspondence display is recorded in the ROM 16 in advance.

The upper part of the corresponding diagram represents the case where an image recorded normally without being reversed left and right at the time of photographing is reproduced, and the lower part represents the case of reproducing an image recorded by inverting left and right at the time of photographing.
The left column of the correspondence diagram represents the case where reproduction is performed without being reversed left and right during reproduction (ie, inversion OFF), and the right column is the case where reproduction is performed while being reversed left and right during reproduction (ie, inversion ON).
The original motif of the arrow indicates the inversion / non-inversion of the recorded moving image, which can be determined by the direction of “R”. That is, if the motif (“R”) at the base of the arrow (left side of the arrow) is a normal image, it can be seen that the reverse recording is an image recorded with OFF (that is, the normal image is recorded). If the original motif (“R”) of the arrow is a mirror image, it can be understood that the image is recorded with reverse recording turned on (that is, a mirror image is recorded).

  The motif at the end of the arrow indicates the state of playback when the reverse icon 900 (generic name for 901 to 904) is tapped and the reverse playback is turned on, and can be determined by the direction of “R”. That is, if the motif (“R”) at the tip of the arrow (on the right side of the arrow) is a normal image, the orientation of the image displayed when reverse playback is turned on becomes a normal image with respect to the actual subject. I understand that. If the motif (“R”) at the tip of the arrow (on the right side of the arrow) is a mirror image, it can be seen that the orientation of the image displayed when reverse playback is turned on is a mirror image with respect to the actual subject. The reverse icon 900 is a reverse icon 900 that toggles between valid / invalid every time it is tapped, and the color of the background of the reverse icon 900 (the display form outside the motif portion in the icon) changes.

  In the following drawings, the shaded area is orange (one display form). An orange color (diagonal line) indicates valid (ie, reverse ON), and a black color (the other display form) indicates invalid (ie, reverse off). That is, if the background color of the reverse icon 900 is black, it can be seen that the reverse reproduction is currently off, and the current state is the state represented by the motif at the base of the arrow (left side of the arrow).

  It can also be seen that if the reverse icon 900 is tapped to turn on reverse playback, the state can be switched to the state represented by the motif at the tip of the arrow (the right side of the arrow). On the other hand, if the background color of the reverse icon 900 is orange, it can be seen that reverse playback is currently on and the current state is the state represented by the motif at the tip of the arrow (right side of the arrow). It can also be seen that if the reverse icon 900 is tapped to turn off the reverse reproduction, the state can be switched to the state represented by the motif of the original arrow (left side of the arrow).

  By displaying such four patterns of inversion icons, it is possible for the user to easily identify whether or not the currently reproduced image has been reversed left and right at the time of shooting. Also, the user can easily identify whether the currently reproduced image is the original left or right (that is, whether the image is a normal image or a mirror image of the actual subject). Furthermore, it is possible for the user to easily identify whether the currently displayed image is an image that has been reproduced by performing reversal processing during reproduction. Further, after the reverse icon 900 is pressed (that is, when the reverse processing function at the time of reproduction is switched on / off), the user can easily identify how the image is reproduced.

  FIG. 9A shows a screen when a normal recorded image is reproduced with reproduction inversion OFF. FIG. 9B shows a screen when a normal recorded image is played back with playback inversion ON, and FIG. 9C shows a screen when the reverse recording image is played back with playback inversion OFF. FIG. 9 (d) shows a screen when playback is performed with playback reverse ON.

A process for performing the above-described reproduction display will be described.
FIG. 11 shows a flowchart of the reproduction process in the reproduction mode. This processing is realized by developing a program recorded in the ROM 16 in the RAM 17 and executing it by the control unit 10. When the digital camera 100 is activated in the playback mode and any of the moving image thumbnails displayed on the index screen is tapped, the processing in FIG. 11 is started.

  In S <b> 1101, the control unit 10 reads a moving image corresponding to the tapped thumbnail from the removable recording medium 19. Also, the attribute information of the moving image is read. If the read attribute information includes a left / right reversal flag, the moving image to be reproduced is a mirror image moving image recorded in the reverse recording mode, and if the left / right reversal flag is not given, the reproduced moving image is a normal image. Information on whether or not the left / right reversal flag has been assigned is stored in the RAM 17.

  In S1102, the control unit 10 reproduces the moving image read in S1101 and displays it on the display unit 14. Further, the reversing icon 900 is initially drawn based on the information of the left / right reversal flag held in the RAM 17. Since the reverse reproduction is not performed in S1102, if the video does not have the left / right reverse flag, the reverse display icon 901 in the upper left display form of FIG. 10 (a) is used, as shown in the display example of FIG. 9 (a). Display.

In the case of a moving image with a left / right reversal flag, a display like the display example of FIG. 9C is performed using the reversal icon 903 in the lower left display form of FIG.
In step S <b> 1103, the control unit 10 determines whether a tap operation has been performed on the reverse icon 900. If there is a tap operation on the reverse icon 900, the process proceeds to S1104, and if not, the process proceeds to S1113.

In step S1104, the control unit 10 refers to the RAM 17 and determines whether or not reverse reproduction is currently being performed. If the reverse reproduction is being performed, the process proceeds to S1105, and if not, the process proceeds to 1109.
In step S1105, the control unit 10 turns off the reverse playback, and plays back and displays the moving image being played back without being reversed. Further, the fact that reverse reproduction is off is recorded in the RAM 17.

In S <b> 1106, the control unit 10 refers to the RAM 17 and determines whether or not the moving image being reproduced has a left / right inversion flag. If the left / right reversal flag is attached, the process proceeds to S1108; otherwise, the process proceeds to S1107.
In S1107, the control unit 10 displays the reverse icon 900 in the upper left display form (901) of FIG. 10A, which is the first display form. At this time, the moving image is displayed as a normal image. As a result, the display as shown in FIG.

In S1108, the control unit 10 displays the reverse icon 900 in the lower left display form (903) of FIG. 10A, which is the second display form. At this time, since the recorded moving image is a mirror image, a mirror image moving image is displayed. As a result, the display as shown in FIG.
On the other hand, in S1109, the control unit 10 turns on the reverse reproduction, and from the time point, the moving image being reproduced is subjected to the horizontal reversal processing by the image processing unit 13 to be reproduced and displayed. Further, the fact that reverse reproduction is on is recorded in the RAM 17.

In step S1110, the control unit 10 refers to the RAM 17 and determines whether or not the moving image being reproduced has a left-right inversion flag. If the left / right reversal flag is attached, the process proceeds to S1112; otherwise, the process proceeds to S1111.
In S1111, the control unit 10 displays the reverse icon 900 in the display form (902) at the upper right in FIG. 10A, which is the third display form. At this time, the moving image is displayed as a mirror image. As a result, the display as shown in FIG.

In S1112, the control unit 10 displays the reverse icon 900 in the lower right display form (904) of FIG. 10A, which is the fourth display form. At this time, since the recorded moving image is a mirror image, a moving image of a normal image obtained by further horizontally reversing it is displayed. As a result, the display as shown in FIG.
In S <b> 1113, the control unit 10 determines whether or not the user has instructed to stop the reproduction of the moving image, or whether or not the reproduction has been stopped by reproducing the moving image to the end. If the reproduction is stopped, the process of FIG. 11 is terminated. If not, the process returns to S1103 to repeat the process.
