Since the image is reproduced above, there is no occurrence of a portion where the image is not displayed on the display screen by rotating the image, and the moving image can be reproduced in an easy-to-view manner.

  According to the third aspect of the present invention, when a vertical / horizontal sensor that detects the inclination state of the moving image recording / reproducing apparatus in the vertical or horizontal direction is used as the inclination detecting unit, the time and the horizontal state change in advance when the moving image is reproduced. Rotation starts from the frame image to be played before the set reference time, and playback is performed by gradually changing the rotation angle of each frame image up to the frame image at the time when the vertical and horizontal state changes. Even if it is used, the horizontal position of a series of moving images can be reproduced in an easy-to-view manner according to the actual horizontal direction.

  According to the seventh and fourteenth aspects of the present invention, in the moving image recording device, the tilt state of the moving image recording device is detected when each frame image constituting the moving image is captured, and the detected tilt state of the device is determined. Based on the rotation, the horizontal position in each frame image is corrected and recorded by rotating each frame image. Therefore, even if a playback device that plays back moving images does not support image rotation, the horizontal position of a series of moving images is always played back in an easy-to-view manner regardless of the shooting angle during movie shooting. It becomes possible to do.

  According to the eighth aspect of the present invention, the direction of the image can be changed only when the vertical / horizontal state of the video recording apparatus is changed reliably, not when the video is played back, and when the video is played back. It is possible to correct the horizontal position.

  According to the ninth and fifteenth aspects of the present invention, in the moving image reproducing apparatus, each frame image constituting the moving image is associated with inclination information indicating the inclination state of the moving image recording apparatus at the time of shooting the frame image. If it is, the horizontal position in each frame image is corrected by rotating each frame image based on the tilt information and reproduced. Therefore, regardless of the shooting angle at the time of moving image shooting, the horizontal position of a series of moving images can always be reproduced in an easy-to-view manner according to the actual horizontal direction.

  According to the tenth aspect of the present invention, when reproducing a moving image, a maximum rectangular image that can be cut out from the rotated frame image with the aspect ratio of the display screen is cut out, and the cut-out image is enlarged to the size of the display screen. Since the image is reproduced above, there is no occurrence of a portion where the image is not displayed on the display screen by rotating the image, and the moving image can be reproduced in an easy-to-view manner.

  According to the eleventh aspect of the present invention, at the time of moving image reproduction, rotation is started from a frame image reproduced before a reference time set in advance from a time point when the vertical and horizontal information changes, and until a frame image at a time point when the vertical and horizontal information changes. Since the playback is performed by changing the rotation angle of each frame image step by step, even if a vertical and horizontal sensor is used, the horizontal position of a series of moving images can be reproduced in an easy-to-view manner according to the actual horizontal direction. Is possible.

  According to the twelfth aspect of the present invention, the direction of the image can be changed only when the state of the vertical / horizontal orientation of the image is changed reliably, not during the playback of the moving image. It is possible to correct the horizontal position.

Display on the screen.

FIG. 2 is a diagram illustrating a detailed configuration of the imaging unit 16 as an imaging unit that captures a moving image. Here, the imaging unit 16 will be described with reference to FIG.
The subject image that has passed through the lens (imaging lens) 31 is formed on a CCD (Charge Coupled Diode) 33 via a diaphragm mechanism 32. In the lens 31 and the diaphragm mechanism 32, the lens position is moved for focusing by the optical system driving unit 34, and the diaphragm amount is controlled so as to achieve appropriate exposure. For the movement of the lens 31 and the diaphragm mechanism 32, detection values detected by a sensor unit 35 including a distance measuring sensor and a light amount sensor are output to the CPU 11 via the bus 21, and are calculated based on the detection values by the CPU 11. Driving is performed by outputting a signal indicating the amount of movement of the lens 31 and the amount of aperture of the aperture mechanism 32 to the optical system drive unit 34.

  When the subject is imaged on the CCD 33, charges corresponding to the amount of incident light are accumulated in the CCD 33, and the charges are read at regular intervals by a drive pulse signal supplied from the drive circuit 36 and output to the analog processing circuit 37. Is done. The analog processing circuit 37 performs various processes such as color separation, gain adjustment, and white balance, and the processed signal is buffered as digital image data (hereinafter referred to as image data) via the A / D conversion circuit 38. 39. This image data is image data of a frame image constituting a moving image.

  The image data stored in the buffer register 39 is converted into a luminance signal and a color difference signal by the signal processing circuit 40 based on a control signal from the CPU 11 and displayed on the display unit 15. The image data processed in the signal processing circuit 40 is compressed in the compression / decompression circuit 41 based on a control signal from the CPU 11 and sequentially stored in the temporary image storage area 131 of the RAM 13 shown in FIG. When a series of moving images are captured, the image data of the series of frame images stored in the image temporary storage area 131 of the RAM 13 is stored as one moving image file in the captured image recording area 171 or the recording medium 18a. To be recorded.

  Returning to FIG. 1, the recording unit 17 includes a non-volatile memory such as a flash memory and the like, a system program corresponding to the electronic camera 100, and a moving image recording process A program and a moving image reproduction process A program that can be executed on the system program And various processing programs, application programs, and data processed by these programs are recorded.

  The recording unit 17 has a captured image recording area 171 for recording a captured moving image file.

  The recording medium driving unit 18 is a driving circuit for recording data such as a moving image file on the mounted recording medium 18a, and reading and reproducing already recorded data. As the recording medium 18a to be mounted, various recording media such as smart media (registered trademark), memory stick (registered trademark), compact flash (registered trademark), SD card, PC card, IC card, and MO (magneto-optic) are available. A recording medium driving unit 18 corresponding to any one or a plurality of recording media can be used.

  The vertical / horizontal sensor 19 is a sensor built in the electronic camera 100, detects the vertical / horizontal state of the casing of the electronic camera 100 (whether the casing is in a horizontal orientation or a vertical orientation), and detects the detection information. This is output to the CPU 11. The landscape orientation is an orientation (the orientation shown in FIG. 3A) in which the display screen of the display unit 15 is landscape when the electronic camera 100 is held in a normal photographing posture. The portrait orientation is the orientation (the orientation shown in FIG. 3B) in which the display screen becomes vertically long when shooting. As the vertical / horizontal sensor 19, for example, a conductive liquid is injected into a cylindrical member having two electrodes, and the vertical / horizontal state of the cylindrical member changes according to the vertical / horizontal state change of the casing of the electronic camera 100. It is possible to use a device that detects the vertical / horizontal state of the casing of the electronic camera 100 by detecting a change in contact with the electrode (for example, see Japanese Patent Application Laid-Open No. 11-174814).

  Note that the housing of the electronic camera 100 is in the horizontal state as a reference state, and reproduction is performed as if the image is viewed in the horizontal state shown in FIG. For this reason, when a frame image shot in a portrait orientation as shown in FIG. 4 (a) is displayed as it is without being rotated, its horizontal position is changed to an actual horizontal direction as shown in FIG. 4 (b). The horizontal position is displayed by being shifted by 90 degrees counterclockwise as compared with the case (FIG. 4A).

  The timer 20 measures time according to an instruction from the CPU 11.

Next, the operation of the first embodiment will be described.
FIG. 5 is a flowchart showing the moving image recording process A executed by the CPU 11 of the electronic camera 100. This processing is realized by software processing in cooperation with the CPU 11 and the moving image recording processing A program stored in the recording unit 17, and is executed when the recording switch 121 is pressed to start recording. Process.

  When the start of recording is instructed, a frame image is captured by the imaging unit 16, and the image data of the captured frame image is stored in the image temporary storage area 131 of the RAM 13 (step S1). When the captured image data is the image data of the first frame (step S2; YES), the detection information from the vertical / horizontal sensor 19 is acquired, and this detection information is obtained when the first frame of the casing of the electronic camera 100 is captured. Is stored in the vertical / horizontal state storage unit 132 of the RAM 13 (step S3), and based on the detection information, a vertical / horizontal flag (vertical / horizontal information) is set in the captured image data (step S4). Specifically, the frame number of the captured image data. The vertical and horizontal flags indicating the vertical and horizontal states as the tilt state of the electronic camera 100 are associated with each other and stored in the header information area 133 of the RAM 13, and the process proceeds to step S13.

  FIG. 6 shows the relationship between the detection information output from the vertical / horizontal sensor 19, the vertical / horizontal flag, and the vertical / horizontal state of the electronic camera 100. As shown in FIG. 6, when the electronic camera 100 is in the vertical orientation, the detection information output from the vertical / horizontal sensor 19 is “1” and the vertical / horizontal flag is “1”. When the electronic camera 100 is in the horizontal orientation, the detection information output from the vertical / horizontal sensor is “0”, and the vertical / horizontal flag stores “0”.

  When image data other than the first frame is taken in (step S2; NO), detection information from the vertical / horizontal sensor 19 is acquired (step S5) and stored in the acquired detection information and vertical / horizontal state storage unit 132. By comparison with the detected information, it is determined whether or not the tilt state of the electronic camera 100 has changed from the tilt state detected immediately before (step S6). When it is determined that the tilt state of the housing of the electronic camera 100 has changed (step S6; YES), the timer 20 starts timekeeping (step S7), and new detection information from the vertical and horizontal sensor 19 is stored in the vertical and horizontal state storage unit. 132 (step S8), and the process proceeds to step S13.

  On the other hand, when it is determined that the tilt state of the electronic camera 100 has not changed (step S6; NO), it is determined whether or not the timer 20 is currently measuring time and when it is determined that time is being measured ( Step S9; YES), it is determined whether or not a preset reference time has elapsed since the tilt state of the electronic camera 100 has changed based on the time measurement result of the timer 20, and it is determined that the reference time has passed in advance. If so (step S10; YES), the timer 20 stops counting (step S11), and the electronic camera 100 is based on the detection information stored in the vertical / horizontal state storage unit 132 in the image data of the frame image captured in step S1. A vertical / horizontal flag indicating the vertical / horizontal state of the tilt state is set (step S12), and the process proceeds to step S13.

  On the other hand, if it is determined in step S9 that the timer 20 is not currently counting (step S9; NO), or if it is determined in step S10 that a preset reference time has not elapsed (step S10; NO), the process proceeds to step S13.

  Until the recording switch 121 is pressed and an instruction to stop recording is given, the processes of steps S1 to S12 are repeatedly executed. In step S1, the frame image is captured at regular time intervals. When the recording switch 121 is pressed and an instruction to stop recording is given (step S13; YES), it is associated with a series of image data stored in the temporary image storage area 131 and each image data stored in the header information area 133. The moving image file with the vertical / horizontal flag set to 1 is recorded in the captured image recording area 171 or the recording medium 18a of the recording unit 17 (step S14), and this process ends.

  FIG. 7 is a diagram showing a data storage example of the moving image file recorded in the captured image recording area 171 or the recording medium 18a in step S14 of FIG. As shown in FIG. 7A, the recorded moving image file includes header information and a frame number. 1 to N frame image data. FIG. 7B is a diagram illustrating a data storage example of header information. In the header information, as shown in FIG. 7B, each frame NO. In addition, the vertical and horizontal flags at the time of shooting the frame image are stored in association with each other. Thereby, each frame image is associated with the vertical and horizontal flags.

  According to the moving image recording process A described above, a series of moving images is shot, and the vertical and horizontal flags corresponding to the change in the tilt state of the casing of the electronic camera 100 at the time of shooting are set for each frame image constituting the series of moving images. Records in association with image data. Therefore, if the tilt state of the electronic camera 100 changes during the shooting of a series of moving images, this can be recognized by the device or another playback device. Also, the vertical / horizontal flag is set only when the reference time has elapsed since the change in the tilt state. Can be recognized by the playback device.

  Next, the moving image reproduction process A executed when reproducing the moving image file recorded in the above-described moving image recording process A will be described. FIG. 8 is a flowchart showing the moving image reproduction process A executed by the CPU 11 of the electronic camera 100. This process is a process realized by software processing in cooperation with the CPU 11 and the moving image reproduction processing A program stored in the recording unit 17, and a reproduction is started when a moving image file is designated and the reproduction switch 122 is pressed. This process is executed when instructed. In the moving image reproduction process (moving image reproduction processes A to C) described below, the display time of each frame image during reproduction is controlled to be constant.

  First, image data of a frame image to be displayed is read out to a work area of the RAM 13 from the moving image file to be reproduced (step S21), and the vertical and horizontal flags corresponding to the read image data are referred to. It is determined whether or not is an image taken in a portrait orientation. If it is determined that the image data is not an image photographed in the portrait orientation (step S22; NO), the process proceeds to step S26 and is displayed on the display screen of the display unit 15, and the process is step S27. Migrate to

  On the other hand, when it is determined that the read image data is an image photographed in the portrait orientation (step S22; YES), the image data is rotated 90 degrees clockwise (step S23), and the image data after the rotation is rotated. The image data having the maximum aspect ratio of the display screen of the display unit 15 is cut out from the image data (step S24), and the cut out image data is enlarged to the size of the display screen (step S25). The enlarged image data is displayed on the display screen (step S26), and the process proceeds to step S27. FIG. 9 schematically shows the process of steps S23 to S25 for the image data of the read frame image.

  In step S27, it is determined whether or not the displayed image data is the last frame image in the moving image file to be reproduced. If it is not the last frame image (step S27; NO), the process returns to step S21. The processing after step S21 is repeatedly executed. If the displayed image data is the final frame image in the moving image file to be played back (step S27; YES), playback is stopped (step S28), and this process ends.

  According to the above-described moving image reproduction process A, in a series of moving image files, in a portion corresponding to a vertical / horizontal flag indicating that the electronic camera 100 was shot in the vertical orientation, the display screen is in the horizontal orientation with the same orientation. When displayed, the horizontal position of the displayed image does not match the actual horizontal direction and the image is difficult to see.Therefore, the image data of the location shot in the tilted state of the vertical orientation is rotated to adjust the horizontal position of the displayed image. By adjusting to the actual horizontal direction, a series of moving images can be easily reproduced. In addition, by cutting out the image with the maximum aspect ratio of the display screen from the rotated image and displaying the cut-out image enlarged to the size of the display screen, there is no part where the image is not displayed on the display screen. It is also possible to reproduce the image of the place where the image is performed in an easy-to-see manner.

(Embodiment 2)
Next, Embodiment 2 of the present invention will be described.
Since the configuration of the second embodiment is the same as that of the electronic camera 100 described with reference to FIGS.
Also, the recording operation of the second embodiment is the same as the moving image recording process A described above, and therefore the description thereof is omitted.

Hereinafter, an image reproduction operation according to the second embodiment will be described.
FIG. 10 is a flowchart showing the moving image reproduction process B executed by the CPU 11 of the electronic camera 100. This processing is realized by software processing in cooperation with the CPU 11 and the moving image reproduction processing B program stored in the recording unit 17, and the reproduction is started when the moving image file is designated and the reproduction switch 122 is pressed. This process is executed when instructed.

  In the second embodiment as well, when a moving image is reproduced, it is assumed that the display screen is reproduced in a landscape orientation (the orientation of FIG. 3A).

  First, image data of a frame image to be displayed is read out to a work area of the RAM 13 in a moving image file to be reproduced (step S31), and a vertical / horizontal flag corresponding to the read image data is referred to. It is determined whether or not is an image taken in a portrait orientation. When it is determined that the image data is not an image photographed in the portrait orientation (step S32; NO), the image data is displayed on the display screen of the display unit 15 (step S34), and the process proceeds to step S35.

  On the other hand, when it is determined that the image data of the read frame image is an image taken in the portrait orientation (step S32; YES), the image data is rotated 90 degrees clockwise (step S33). The rotated image data is displayed on the display screen of the display unit 15 (step S34), and the process proceeds to step S35.

  In step S35, image data in which the content of the vertical / horizontal flag changes next is searched (step S35). If the content of the vertical / horizontal flag changes from the horizontal state to the vertical state (step S36; YES), in step S35. The image data up to a preset number of frames (n + 1 (n is a positive integer) frame) ahead of the retrieved image data is read out to the work area of the RAM 13 and sequentially displayed on the display screen of the display unit 15. (Step S37). When the content of the vertical / horizontal flag changes from the vertical orientation to the horizontal orientation (step S36; NO), the number of frames set in advance from the image data searched in step S35 (n + 1 (n is a positive integer) frame) The previous image data is read out to the work area of the RAM 13 and is sequentially rotated 90 degrees clockwise and displayed on the display screen of the display unit 15 (step S38). If the number P of images up to the next time when the vertical and horizontal flags change is less than n, the image data is not read out in step S36.

  Next, the image data of the next frame image to be displayed is read into the work area of the RAM 13 (step S39), and the number of frames (number of frames) from the read frame image to the frame image where the vertical / horizontal flag changes next. Based on the above, the rotation angle of the image is determined, and rotation processing is performed at the determined rotation angle (step S40). The determined rotation angle is stepwise at a constant rate for each image from the image data before n frames (P frame when n> P) when the vertical / horizontal flag changes to the image data where the content of the vertical / horizontal flag changes. Change. For example, when the vertical / horizontal flag changes from a horizontal flag to a vertical flag, the image data at the time when the rotation is started (the image before n frames before the vertical / horizontal flag changes (when n> P, before the P frame) (Data) is 1, and when the number M of read image data is counted, the rotation angle for each image is clockwise (90 / n + 1) × M degrees (when n> P, (90 / P + 1) × M degrees). To be determined.

After the rotation, the image data is displayed on the display screen of the display unit 15 (step S41).
The processes in steps S39 to S41 are repeatedly executed until the contents of the vertical / horizontal flag corresponding to the displayed image data change. If the content of the vertical / horizontal flag corresponding to the displayed image data has changed (step S42; YES), the process proceeds to step S43, and whether the displayed image data includes the final image data in the moving image file to be reproduced. If it is determined that the image data is not the final image data (step S43; NO), the process returns to step S35, and the processes after step S35 are repeatedly executed. When the displayed image data is the final image data in the moving image file to be played back (step S43; YES), playback is stopped (step S44), and this process ends.

  FIG. 11 is a diagram schematically illustrating each frame image of a moving image file and a reproduction image when the moving image file is reproduced by executing the above-described moving image reproduction process B. FIG. 10A is a diagram showing the contents of each frame image and the vertical / horizontal flag corresponding to each frame image in the moving image file. FIG. 10B is a diagram showing the moving image file shown in FIG. It is a figure which shows the rotation angle and reproduction image which are rotated when performing and reproducing | regenerating.

  The vertical / horizontal sensor 19 outputs detection information indicating whether the casing of the electronic camera 100 is in a vertical state or a horizontal state, and detection information indicating vertical or horizontal when the casing is rotated by a predetermined angle or more. Is switched. In other words, the casing is gradually rotated before the vertical / horizontal sensor 19 detects the vertical / horizontal switching. For example, in the moving image file shown in FIG. 11A, the image data of the first frame is associated with the vertical and horizontal flags with the horizontal flag, and the image data of the seventh frame is associated with the vertical flag. However, actually, the tilt of the housing of the electronic camera 100, that is, the shooting angle is changed and the horizontal position of the image is also changed until the vertical / horizontal switching is performed with the image data of the seventh frame. is doing. In the above-described moving image reproduction process B, the frame image to be reproduced from the image data n frames before the next image data in which the vertical / horizontal flag changes, in other words, the next time before the reference time set in advance from the change in the vertical / horizontal flag. Since the rotation angle of each frame image up to the frame image at the time when the vertical / horizontal flag changes is changed in stages and rotated, the image is displayed horizontally as shown in FIG. It becomes possible to reproduce the image in an easy-to-view manner by matching the direction position with the actual horizontal direction.

Next, a third embodiment of the present invention will be described.
In the first and second embodiments, the vertical / horizontal flag indicating whether each piece of image data constituting a series of moving image files was shot with the casing of the electronic camera 100 in the vertical state or in the horizontal state at the time of shooting. By storing them in association with each other and rotating the frame image based on the vertical / horizontal flag during moving image reproduction, the horizontal position of the image can be reproduced in an easy-to-view manner in accordance with the actual horizontal direction. The third embodiment is a case where the electronic camera 100 or another playback device does not support image rotation processing by rotating and recording a frame image based on detection information from the vertical / horizontal sensor 19 during shooting. Even if it is easy to see, it can be reproduced.

  Since the configuration of the third embodiment is the same as that of the electronic camera 100 described with reference to FIGS.

Next, the operation of the third embodiment will be described.
FIG. 12 is a flowchart showing the moving image recording process B executed by the CPU 11 of the electronic camera 100. This processing is realized by software processing in cooperation with the CPU 11 and the moving image recording processing B program stored in the recording unit 17, and is executed when the recording switch 121 is pressed to start recording. Process.

When the start of recording is instructed, the image data of the frame image is captured by the imaging unit 16 and stored in the temporary image storage area 131 of the RAM 13 (step S51). When the captured image data is the first frame (step S52; YES), detection information from the vertical / horizontal sensor 19 is acquired and stored in the vertical / horizontal state storage unit 132 of the RAM 13 (step S53). In addition, it is determined whether the image data captured based on the detection information from the vertical / horizontal sensor 19 is captured in the vertical state or the horizontal direction, and is image data captured in the vertical direction (step S54; YES). ), The image data is read into the work area of the RAM 13 and rotated 90 degrees clockwise (step S55), and the image is cut out from the rotated image data according to the aspect ratio of the display screen. The image is enlarged to the size of the image data before cutting (step S56), the corresponding image data in the image temporary storage area 131 is replaced with the processed image data (step 57), and the process proceeds to step S69.
On the other hand, if it is determined in step S54 that the captured image data is not image data captured in the portrait orientation (step S54; NO), the process proceeds to step S69.

  If the image data captured by the imaging unit 16 is not the first frame image (step S52; NO), the process proceeds to step S58, and detection information from the vertical / horizontal sensor 19 is acquired and the acquired detection is performed. By comparing the information with the detection information stored in the vertical / horizontal state storage unit 132, it is determined whether or not the tilt state of the electronic camera 100 at the time of image capture has changed from the tilt state detected immediately before (step). S59). When it is determined that the tilt state of the electronic camera 100 has changed (step S59; YES), the time measurement by the timer 20 is started (step S60), and the detection information from the vertical / horizontal sensor 19 is stored in the vertical / horizontal state storage unit 132 ( In step S61), the process proceeds to step S69.

  On the other hand, when it is determined in step S59 that the tilt state of the electronic camera 100 has not changed (step S59; NO), it is determined whether or not the timer 20 is currently measuring time, and it is determined that time is being measured. If it is determined (step S62; YES), it is determined whether or not a preset reference time has elapsed since the tilt state of the electronic camera 100 has changed based on the time measurement result of the timer 20, and a preset reference time is determined. Is determined to have elapsed (step S63; YES), the timer 20 stops counting (step S64). Next, based on the detection information stored in the vertical / horizontal state storage unit 132, it is determined whether the captured image data was shot in the vertical state or the horizontal direction, and is image data shot in the vertical state. (Step S65; YES), the image data is read into the work area of the RAM 13 and rotated clockwise by 90 degrees (step S66), and the rotated image data is used in accordance with the aspect ratio of the display screen. The image is cut out, further enlarged to the image data size before cutting out (step S67), and the corresponding image data in the temporary image storage area 131 is replaced with the processed image data (step 68). Proceeds to step S69.

  On the other hand, if it is determined in step S62 that the timer 20 is not currently counting (step S62; NO), if it is determined in step S63 that a preset reference time has not elapsed (step S63; NO) Alternatively, if it is determined in step S65 that the image data is not photographed vertically (step S65; NO), the process proceeds to step S69.

  Until the recording switch 121 is pressed and recording stop is instructed, the processes of steps S51 to S68 are repeatedly executed. The capture of the frame image in step S51 is performed at regular time intervals. When the recording switch 121 is pressed and recording is instructed (step S69; YES), the image data of the series of frame images stored in the image temporary storage area 131 of the RAM 13 is taken as one moving image file and is taken by the recording unit 17. Recording is performed in the recording area 171 or the recording medium 18a (step S70), and this process ends.

  According to the moving image recording process B described above, the image is rotated and recorded based on the detection information from the vertical / horizontal sensor 19 at the time of shooting, and therefore the electronic camera 100 or other playback device does not support the image rotation process. Even so, if the image data is reproduced as it is, the horizontal position of the image can be matched with the actual horizontal position, and a series of moving images can be easily reproduced. Even if the tilt state of the electronic camera 100 changes, the orientation of the image is not changed unless the tilt state continues until the reference time elapses. Only in this case, the orientation of the image can be changed, and the horizontal position can be efficiently corrected. In addition, when the image with the maximum aspect ratio of the display screen is cut out from the rotated image data, and the cut-out image is enlarged and recorded to the size of the original image data, so that the electronic camera 200 reproduces the image. In addition, there is no portion where no image is displayed on the display screen, and it is possible to reproduce the image more easily.

It is stored in association.

  According to the above-described moving image recording process C, a series of moving images are shot, and angle information corresponding to a change in the tilt angle of the housing of the electronic camera 200 at the time of shooting is used for each frame image constituting the series of moving images. Records in association with image data. Accordingly, when the tilt angle of the electronic camera 200, that is, the shooting angle changes during the shooting of a series of moving images, this can be recognized by the device or another playback device.

  Next, the moving image reproduction process C executed when reproducing the moving image file recorded in the above-described moving image recording process C will be described. FIG. 15 is a flowchart showing the moving image reproduction process C executed by the CPU 11 of the electronic camera 200.

This process is executed when instructed.

  In the present embodiment, when a moving image is reproduced, it is assumed that the display screen is reproduced in a landscape orientation (the orientation of FIG. 3A).

  First, image data of a frame image to be displayed is read out from the movie file to be reproduced into the work area of the RAM 13 (step S91), and angle information corresponding to the read image data is referred to. Based on this, the image data is rotated (step S92). In the present embodiment, the image data is rotated clockwise at a rotation angle indicated by the angle information.

  Next, the image data with the maximum aspect ratio of the display screen of the display unit 15 is cut out from the rotated image data (step S93), and the cut out image data is enlarged to the size of the display screen (step S93). S94). Then, the enlarged image data is displayed on the display screen (step S95), and the process proceeds to step S96.

  In step S96, it is determined whether or not the displayed image data includes image data of the final frame image in the moving image file to be reproduced. If it is not the image data of the final frame image (step S96; NO), processing is performed. Returns to step S91, and the processing after step S91 is repeatedly executed. When the displayed image data is the image data of the last frame image in the moving image file to be reproduced (step S96; YES), the reproduction is stopped (step S97), and this process ends.

  According to the image reproduction process C described above, in a series of moving image files, the image data of each frame image constituting a series of moving images is rotated and reproduced according to the shooting angle of the electronic camera 200 at the time of shooting. The horizontal position of the image can be adjusted to the actual horizontal direction, and a series of moving images can be easily reproduced. In addition, by cutting out the image with the maximum aspect ratio of the display screen from the rotated image data, and expanding the displayed image to the size of the display screen, there is no part where the image is not displayed on the display screen. It is also possible to reproduce the image of the rotated part in an easy-to-view manner.

(Embodiment 5)
Next, a fifth embodiment of the present invention will be described.
In Embodiment 4, the image data of each frame image constituting a series of moving image files is recorded in association with the tilt angle of the housing of the electronic camera 200 at the time of shooting, that is, angle information indicating the shooting angle. At the time of reproduction, the image is rotated based on the angle information, so that the horizontal position of the image can be reproduced in an easy-to-view manner along with the actual horizontal direction. The fifth embodiment is a case where the electronic camera 200 or another playback device does not support image rotation processing by rotating and recording an image based on angle information from the angle sensor 22 at the time of shooting. It is also possible to reproduce the video in an easy-to-read manner.

  Since the configuration of the fifth embodiment is the same as that described in the fourth embodiment, the description thereof is omitted.

Hereinafter, the operation of the fifth embodiment will be described.
FIG. 16 is a flowchart showing the moving image recording process D executed by the CPU 11 of the electronic camera 200. This processing is realized by software processing in cooperation with the CPU 11 and the moving image recording processing D program stored in the recording unit 17, and is executed when the recording switch 121 is pressed to start recording. Process.

  When the start of recording is instructed, the image data of the frame image is captured by the imaging unit 16 and stored in the temporary image storage area 131 of the RAM 13 (step S101). Next, the captured image data is read out to the work area of the RAM 13, and the detection information of the angle sensor 22 is referred to, and the captured image data is rotated based on the detection information (step S102). Specifically, the rotation processing is performed clockwise at the rotation angle detected by the angle sensor 22. After the rotation, the image data of the maximum rectangular aspect ratio of the display screen of the display unit 15 is cut out from the rotated image data (step S103), and the cut out image data is enlarged to the image data size before the cut out. In step S104, the corresponding image data in the temporary image storage area 131 is replaced with the image data processed in the work area (step S105), and the process proceeds to step S106.

  Until the recording switch 121 is pressed and the recording stop is instructed, the processes of steps S101 to S105 are repeatedly executed. The frame image capture in step S101 is performed at regular time intervals. When the recording switch 121 is pressed and an instruction to stop recording is given (step S106; YES), a series of frame image image data stored in the image temporary storage area 131 of the RAM 13 is taken as one moving image file and the captured image of the recording unit 17 is recorded. Recording is performed in the recording area 171 or the recording medium 18a (step S107), and this process ends.

  According to the moving image recording process D described above, the image data of each frame image is rotated and rotated based on the tilt angle of the casing of the electronic device 200 detected by the angle sensor 20 at the time of shooting, that is, the shooting angle. Since the recorded image data is recorded, even if the electronic camera 200 or another playback device does not support image rotation processing, if the image data is played back as it is, the horizontal position of the image is set to the actual horizontal direction. A series of moving images can be easily reproduced and reproduced. In addition, since the image with the maximum aspect ratio of the display screen is cut out from the rotated image data, and the cut-out image is enlarged and recorded to the size of the original image data, the reproduction is performed with the electronic camera 200. Thus, there is no portion where no image is displayed on the display screen, and playback can be easily performed.

  As described above, according to the electronic cameras 100 and 200, when a moving image is reproduced, even if the casing of the electronic camera is tilted with respect to the reference state when the moving image is captured, the horizontal position of the image is set. It becomes possible to reproduce the video in an easy-to-view manner according to the actual horizontal direction.

  In addition, the description content in the said embodiment is a suitable example of the electronic cameras 100 and 200 which concern on this invention, and is not limited to this.

  For example, in the above embodiment, a moving image recording apparatus that captures and records a moving image and a moving image recording apparatus that reproduces the recorded moving image are described as an example. The image data recorded by performing the above moving image recording process in the moving image recording apparatus may be reproduced by performing the above moving image reproduction process in a separate moving image reproducing apparatus. .

  In the first and third embodiments, the case where the vertical / horizontal flag is set only for image data recognized as having changed the vertical / horizontal state of the casing of the electronic camera at the time of shooting has been described as an example. On the other hand, a vertical / horizontal flag may be set.

  In the first to fifth embodiments, the moving image is reproduced with the display screen in the horizontal direction. However, the present invention can also be applied to the case where the moving image is reproduced in the vertical direction.

  In the first to third embodiments, when the vertical / horizontal state is maintained for a preset reference time after the detection information from the vertical / horizontal sensor 19 is changed in the moving image recording process, the change is reflected in the vertical / horizontal flag. As a result, the orientation of the image can be changed only when the vertical / horizontal state is surely changed instead of a slight blur. However, every time the detection information from the vertical / horizontal sensor 19 changes in the moving image recording process, the vertical / horizontal direction is changed. The flag is changed so as to be recorded in association with the frame image. In the video playback device, the vertical / horizontal state is restored within the preset reference time after the vertical / horizontal state is changed from the content of the vertical / horizontal flag. Is indicated, the rotation angle may not be changed in accordance with the change in the vertical and horizontal states. Accordingly, as in the first to third embodiments, it is possible to change the orientation of the image only when the tilt state is surely changed, not the slight blurring, and the horizontal position of the image can be efficiently performed. Can be corrected.

  In the above embodiment, in the header information of the moving image file, the frame No. The vertical and horizontal flags and the angle information as the tilt information are recorded in association with each other. However, the vertical and horizontal flags and the angle information may be recorded in association with the elapsed time from the start of photographing.

  In addition, an angle sensor may be used as the vertical / horizontal sensor 19, and when the detected rotation angle exceeds a preset reference angle, the switching between the vertical and horizontal states may be recognized on the electronic cameras 100 and 200 side. At this time, the reference angle to be switched may be changed between when switching from the portrait orientation to the landscape orientation and when switching from landscape orientation to portrait orientation. For example, when the horizontal state is detected as a reference state of 0 degrees and the vertical state is detected as 90 degrees, switching from the horizontal direction to the vertical direction is detected when the rotation angle exceeds 70 degrees, and the vertical direction is returned to the horizontal direction. The change of time is detected when the rotation angle is less than 30 degrees. As a result, it is possible to detect the change when the vertical and horizontal states have been changed with certainty instead of a slight blur.

  In addition, the detailed configuration and detailed operation of the electronic cameras 100 and 200 can be changed as appropriate without departing from the spirit of the present invention.
