Description

  The present invention relates to a recording apparatus, and more specifically, to a recording apparatus having a function of erasing a ground shooting portion from a moving image.

  In video cameras capable of shooting moving images, it is common to use the same toggle switch for instructing the start and end (pause) of shooting (recording), and are often installed on the back of the camera.

  In recent years, video cameras have been miniaturized and can be easily operated with only one hand, and can be carried with one hand as it is.

  For this reason, there may often be a situation where the photographer intends to end the shooting but does not actually end the shooting. At this time, for example, the user may drop the hand while holding the camera in the shooting state, and may be in a state of shooting the ground all the time (hereinafter referred to as ground shooting).

  At this time, even if the photographer notices and again performs the shooting end operation, it is inevitable that the ground shooting scene is recorded in vain after the intended shooting scene.

Japanese Patent Application Laid-Open No. 2004-151867 describes a technique for displaying a warning when a ground shooting state is detected and automatically stopping shooting (recording).
JP-A-8-275033

  Even in the technique described in Patent Document 1, the ground is recorded for a period from when the ground shooting is detected until the shooting is stopped.

  In the technique described in Patent Document 1, the shooting is automatically stopped when there is no instruction to continue shooting within a predetermined period after the ground shooting warning is displayed. However, issuing a warning display or requesting some operation during shooting is an obstacle to shooting.

  Further, there may be a case where a normal shooting portion intended by the photographer and an unintended unnecessary shooting portion such as ground shooting are mixed during a series of shooting. For this reason, it is desirable to easily erase only unnecessary ground-captured portions of a series of shooting scenes.

The first frame in which the rotation angle exceeds the threshold value in the frame before the transitioned frame is the ground shooting data start point, and the rotation angle of the imaging device has the threshold value in the frame after the frame that has returned from the ground shooting state. One frame before the exceeding frame is set as the end point of ground shooting data.

  Preferably, a recording stop control unit that controls the recording unit to automatically stop recording after a predetermined time has elapsed after the ground shooting detection unit detects the ground shooting.

  Preferably, the ground shooting editing means deletes the ground shooting data starting point and subsequent points set by the ground shooting position setting means after the recording stop by the recording stop control means.

  A recording apparatus according to the present invention is an apparatus that records a moving image signal obtained by photographing a subject, and that records the moving image signal obtained by the imaging unit and a recording medium on the recording medium.

  According to the present invention, it is possible to efficiently erase the ground shooting portion.

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

  A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows a schematic block diagram of an imaging apparatus 10 that is Embodiment 1 of the present invention. FIG. 2 shows a schematic block diagram of the ground shooting editing control unit. FIG. 3 is an external view of the rear surface of the imaging device 10. FIG. 4 is a schematic diagram showing the rotation angle and direction of the imaging apparatus 10. FIG. 5 is a schematic diagram illustrating the relationship between the rotation angle of the imaging device 10 and ground shooting data.

  In FIG. 1, the image input unit 12 of the imaging device 10 includes, for example, a plurality of photographing lenses, a CCD (Charge-Coupled Device) imaging device that converts an optical image into an image signal, and the like. The image signal of the subject input by the image input unit 12 is subjected to image processing by the image processing unit 14 and displayed by the image display unit 16 including a liquid crystal monitor or the like.

  The audio input unit 22 configured with a microphone or the like captures surrounding audio and supplies an audio signal to the audio processing unit 24. The voice processing unit 24 performs voice processing on the voice signal from the voice input unit 22. A sound output unit 26 composed of a speaker or the like outputs the sound signal processed by the sound processing unit 24 as sound.

  In the recording mode, the format control unit 18 converts the image signal or video signal processed by the image processing unit 14 and the audio signal processed by the audio processing unit 24 into a recording format. The recording / reproducing / erasing unit 20 records the image / audio signal in the recording format from the format control unit 18 on the recording medium 42.

  In the reproduction mode, the recording / reproducing / erasing unit 20 reproduces a designated video / audio signal from the recording medium 42 and supplies it to the format control unit 18. The format control unit 18 converts the audio / video signal from the recording / reproducing / erasing unit 20 into a format that can be displayed and output. The format control unit 18 supplies the image signal subjected to the format conversion to the image processing unit 14 and supplies the audio signal to the audio processing unit 24. The image processing unit 14 processes the image signal from the format control unit 18 for display and supplies it to the image display unit 16. The audio processing unit 24 processes the audio signal from the format control unit 18 for output and supplies it to the audio output unit 26. As a result, the reproduced image is displayed on the image display unit 16, and the reproduced audio is output from the audio output unit 26.

  The rotation angle detection unit 32 detects the rotation angle of the imaging device 10 and supplies the detected rotation angle to the recording / reproducing / erasing unit 20 as a detection result. Here, when the optical axis of the lens of the imaging device 10 is parallel to the ground, the degree of detection rotation angle of the imaging device 10 increases as the optical axis of the lens tilts toward the ground. To do. The recording / playback / erasing unit 20 records the detected rotation angle from the rotation angle detection unit 32 as a user information file on the recording medium 42 for each captured image signal, that is, for each frame of the captured video signal. The detected rotation angle may be added as additional information to each image signal.

  The ground shooting detection unit 34 detects the ground shooting state of the imaging apparatus 10. Specifically, it is assumed that the ground shooting detection unit 34 detects the ground shooting state when the rotation angle of the rotation angle detection unit 32 is 90 degrees or more. The recording / reproducing / erasing unit 20 stores the ground shooting state from the ground shooting detection unit 34 in the built-in memory 40 for each captured image signal, that is, for each frame of the captured video signal.

  When the user management information detection unit 38 detects the ground shooting state from the recording medium 42 and the built-in memory 40, the ground shooting editing control unit 36 stores the ground shooting information in the built-in memory 40 via the recording / playback / erasing unit 20. To do.

  The recording stop input unit 28 is used to instruct the imaging device 10 to start and end recording by a toggle operation. When the user instructs the recording stop by the recording stop input unit 28, the recording stop control unit 30 instructs the recording / reproducing / erasing unit 20 to stop the recording. Thereby, the imaging device 10 shifts to a stopped state. When the imaging apparatus 10 finishes recording one continuous scene and shifts to a stop state, the recording / playback / erasing unit 20 reads ground shooting information from the built-in memory 40 and reads a user information file from the recording medium 42. The user management information detection unit 38 detects the rotation angle of the imaging device 10 corresponding to the ground shooting information and the frame. The ground shooting editing control unit 36 sets the ground shooting data start position based on the ground shooting information and the rotation angle information, and the recording / playback / erasing unit 20 transmits the data after the ground shooting data start position to the recording medium 42. Erase from At the same time, the recording / reproducing / erasing unit 20 erases the ground shooting state and ground shooting information from the built-in memory 40.

  With reference to FIG. 2, the configuration and operation of the ground shooting edit control unit 36 will be described in detail. The ground shooting editing control unit 36 includes a ground shooting position setting unit 36a and a ground shooting editing unit 36b.

  The ground shooting position setting unit 36a sets a ground shooting data start point in continuous moving image data from the rotation angle of the imaging device 10 and information on the ground shooting state. The ground shooting editing unit 36b performs control to delete continuous moving image data after the ground shooting data start point set by the ground shooting position setting unit 36a as unnecessary ground shooting data. The CPU 44 controls the operations of the ground shooting position setting unit 36a and the ground shooting editing unit 36b.

  With reference to FIG. 4, the operation of the ground shooting detection unit 34 will be described. In FIG. 4, it is assumed that the state (A) in which the optical axis of the lens of the imaging apparatus 10 is parallel to the ground is 0 °, and the value of the angle increases as the optical axis of the lens is tilted toward the ground. The angle is 45 ° in the state (B) and 90 ° in the state (C). However, the ground shooting detection unit 34 detects the ground shooting state when detecting that the rotation angle of the imaging device 10 is 90 ° or more. When the ground shooting state is detected continuously for 5 seconds, the recording stop control unit 30 shifts the imaging device 10 to the stop state. The user can arbitrarily set the ground shooting state detection method and the conditions for shifting to the stop state after detecting ground shooting.

  The rotation angle of the imaging device 10 is detected in the downward (ground) direction from the state in which the optical axis of the lens is parallel to the ground, but the rotation angle may also be detected in the upward or left-right direction. . In this embodiment, the threshold value of the rotation angle of the imaging device 10 when setting the ground image data is 45 °, but this threshold value can be arbitrarily set by the user.

  With reference to FIG. 5, the relationship between the rotation angle of the imaging device 10 and the ground image data will be described. Recording starts when the photographer presses the recording button (point A). When the rotation angle of the imaging device 10 is always detected, a frame whose rotation angle exceeds 90 ° is set as a ground shooting detection point (point B), and a state where the rotation angle is 90 ° or more has passed for a certain time (5 seconds), Recording is automatically interrupted and paused (point C). The frame (point D) in which the rotation angle exceeds the threshold (45 degrees) for the first time in the frame before point C is set as the ground shooting data start point, and data after point D is erased as unnecessary ground shooting data.

  With reference to FIG. 6, the operation of the ground shooting edit control unit 36 will be described. FIG. 6 is a flowchart showing the operation of the ground shooting edit control unit 36.

  When the function of the present embodiment (ground shooting erasing function) is disabled (S1), when the recording stop input unit 28 is pressed to start recording (S14), the rotation angle of the imaging device 10 is detected (S15). If the ground shooting is detected (S16) and the ground shooting continues for a certain time (5 seconds) (S17), the recording is automatically terminated and the mode is shifted to the stop mode (S18).

  When the function of the present embodiment (ground shooting erasing function) is enabled (S1), when the recording stop input unit 28 is pressed to start recording (S2), the rotation angle of the imaging device 10 is detected (S3), The detected rotation angle is recorded corresponding to the frame of the input video signal (S4).

  If it is not the ground shooting state (S5), the detection start point is cleared (S6), and steps S3, S4, and S6 are repeated until the ground shooting state is detected. If the ground shooting state is detected (S5) and the detection start point is not yet set (S7), this frame is set as the detection start point (S8), and the process returns to S3. When the detection start point has already been set (S7), steps S3 to S7 are repeated until the ground shooting is continued for a certain time (here, 5 seconds) or longer (S9).

  When the ground shooting continues for a certain time (here, 5 seconds) or longer (S9), the detection start point is set as the ground shooting start point (S10), and the recording is automatically stopped (S11). Unnecessary ground shooting data is set from the ground shooting start point and rotation angle information (S12). Then, the data after the set ground shooting start point is deleted from the recording medium 42 as unnecessary data (S13).

  FIG. 7 shows a more detailed flow of step S12 (ground shooting data setting). The ground shooting start point is the Nth frame (S21). n = N is set, and the rotation angle of the nth frame is detected (S22). If the detected rotation angle of the nth frame is smaller than the threshold (45 °) (S23), the n + 1th frame, which is the next frame of the nth frame, is set as the ground shooting data start point (S25).

  When the rotation angle of the nth frame is equal to or greater than the threshold (45 °) (S23), n is decremented (n = n−1), the rotation angle is detected (S24), and steps S23 to S24 are repeated. That is, the frame is traced until the rotation angle is less than 45 degrees.

  In this way, in this embodiment, unnecessary ground shooting data portions are automatically deleted from the recording medium 42 after the recording is stopped.

  A second embodiment of the present invention will be described. In the first embodiment, unnecessary ground shooting data is erased at the time of recording, but in the second embodiment, unnecessary ground shooting data can be deleted at the time of reproduction.

  In the recording mode of the second embodiment, when the imaging apparatus 10 finishes recording one continuous scene and shifts to the stop mode, the recording / playback / erasing unit 20 reads the ground shooting state from the built-in memory 40 and records the recording medium 42. Read user information file from. The user management information detection unit 38 detects the rotation angle of the imaging device 10 corresponding to the ground shooting information and the frame.

  Based on the ground shooting information file and the rotation angle information, the ground shooting editing control unit 36 sets the ground shooting data start position and the ground shooting data end position, adds them to the ground shooting information, and records / plays back / deletes them. To the unit 20. The recording / playback / erasing unit 20 records the ground shooting information from the ground shooting editing control unit 36, the ground shooting data start position, and the ground shooting data end position on the recording medium 42 as a user information file. At the same time, the ground shooting editing control unit 36 also creates a playlist excluding the ground shooting portion and records it on the recording medium 42.

  The playback mode includes a normal menu that displays all recorded scenes and a ground shooting menu that displays only data including ground shooting. When the ground shooting menu is selected, the ground shooting editing control unit 36 displays a thumbnail of data including the ground shooting. Then, it is possible to select and reproduce all the scenes including the ground shooting, any of the portions other than the ground shooting portion in one scene and the ground shooting portion in one scene. In addition, it is possible to select and delete all the scenes including ground shooting, the ground shooting portion in all scenes, one scene including ground shooting, and the ground shooting portion in one scene.

  The file structure of the recording medium 42 will be briefly described. FIG. 8 is a schematic diagram of a file configuration of the recording medium 42. The recording medium 42 has an image folder 50 as an area for storing image (video) files, and an audio folder as an area for storing audio files.

  The image folder 50 contains an information file (image reproduction file) for reproducing an image (video), an actual image (video) data file, and a backup file. The user information file is recorded as a user file (User.info) 52 in association with these image data files in the image folder 50.

  With reference to FIG. 9, the relationship between the rotation angle of the imaging device 10 and the ground image data will be described. Recording starts when the photographer presses the recording stop input unit 28 (point a). The rotation angle of the imaging device 10 is always detected. Frames whose rotation angle exceeds 90 ° are set as ground shooting detection points (points b and d). When the state where the rotation angle is 90 ° or more has passed for a certain time (5 seconds), the points b and d are set as the ground shooting data detection start points. When the ground shooting detection start point is set, detection of the ground shooting detection end point starts.

  One frame before (c point, e point) before the frame where the rotation angle of the imaging device 10 is smaller than 90 ° is set as the ground shooting detection end point. When the photographer presses the recording stop input unit 28, the recording is terminated and the pause mode is set (point f). The frame (g point, i point) before the ground shooting detection start point (b point, d point) and whose rotation angle exceeds the threshold value for the first time is set as the ground shooting data start point. The frame (h point, j point) that is behind the ground shooting detection end point (c point, e point) and whose rotation angle is below the threshold value for the first time is defined as the ground shooting data end point.

  If there is no ground shooting detection end point after the ground shooting data start point, the last frame of one scene is set as the ground shooting data end point. After setting the ground shooting data start point and the ground shooting data end point, a playlist for reproduction is created except for the area between the ground shooting data start point and the ground shooting data end point. Playback and erasure data can be deleted from the ground shooting menu in playback mode.

  With reference to FIG. 10, the operation of the ground shooting edit control unit 36 in the second embodiment will be described. FIG. 10 is an operation flowchart of the ground shooting edit control unit 36 according to the second embodiment.

  When the ground shooting start point is not set (S34), if it is not in the ground shooting state in this frame (S35), the ground shooting detection start point is cleared (S36), and steps S32 to S32 are performed until the ground shooting state is detected. S36 is repeated. In the ground shooting state (S35) and if the ground shooting detection start point is not yet set (S37), this frame is set as the ground shooting detection start point (S38), and the process returns to step S32. Steps S32 to S39 are repeated until the ground shooting detection start point has been set (S37) and the ground shooting is continued for a certain time (5 seconds) (S39). When the ground shooting is continued for a certain time (S39), the ground shooting detection start point is set as the ground shooting start point and recorded in the user information (S40).

  If the ground shooting start point has already been set (S34) and the ground shooting state has been detected (S42), the frame is set as the ground shooting end point and recorded in the user information (S43).

  If the ground shooting start point has already been set (S34) and the ground shooting state is not detected in the current frame (S42), the currently set ground shooting end point is recorded in the user information (S44). Then, the ground shooting start point set at the present time is cleared. If the recording is not finished (S41), steps 32 to S45 are repeated. If the recording is finished (S41), ground shooting data is set from the recorded ground shooting start point and ground shooting end point and recorded in the user information (S46).

  FIG. 11 shows a detailed flowchart of setting of the ground image data (S46) in FIG. The frame at the ground shooting detection start point (referred to as the S-th frame) is detected (S51). S is set in the variable n, and the rotation angle of the imaging device 10 of n frames is detected (S52). If the rotation angle of the imaging device 10 in the n frame is 45 ° or more (S53), n is decremented, the rotation angle of the imaging device 10 in the n frame is detected (S54), and it is checked whether it is 45 ° or more ( S53). That is, the frame is traced until the rotation angle of the imaging device 10 is less than 45 °. If the rotation angle of the imaging device 10 in n frames is less than 45 ° (S53), n + 1 frames are set as the ground shooting data start point (S55).

  If the frame of the ground shooting detection end point corresponding to the ground shooting detection start point used for setting the ground shooting data start point (E frame) is detected (S56), E is set to the variable m. Then, the rotation angle of the imaging device 10 in the m frame is detected (S57). Until the rotation angle becomes less than 45 ° (S58), m is incremented (S59). When the rotation angle is less than 45 ° (S58), the m-1 frame is set as the ground shooting data end point (S60).

  If there is a ground shooting detection start point other than those already used (S61), Steps S51 to S60 are repeated.

  FIG. 12 shows a flowchart of the ground shooting data editing operation. If the recording mode is selected (S71), a playlist for reproduction is created every time recording of one scene is completed (S72). If the ground shooting menu is selected (S74) instead of the recording mode (S71) and the playback mode (S73), only the scenes including the ground shooting are created and displayed (S75).

  When a certain ground shooting scene is selected (S76) and a reproduction command is selected (S77), reproduction processing is executed (S78). If an erase command is selected (S79), an erase process is executed (S80). Steps S76 to S81 are repeated until the playback menu is changed, the playback mode ends, or the power is turned off (S81).

  FIG. 13 shows a flowchart of the reproduction processing of the ground image data. For the selected scene, when playback of all one scene including the ground shooting portion is selected (S91), all one scene is played (S92). When the reproduction excluding the ground shooting portion is selected (S93), the scene is reproduced in accordance with the play list for reproducing the ground shooting portion created after the recording is completed (S94). When the ground shooting part reproduction is selected (S95), when there are a plurality of ground shooting parts in one scene, the ground shooting part to be played back is selected (S96), and only the selected ground shooting part is played back (S96). S97).

  FIG. 14 shows a flowchart of the erasure process of the ground image data. When the number of selected scenes is one (S101), and when all deletion of one scene including the ground shooting portion is selected (S102), all the selected scenes are deleted from the recording medium (S103). When erasing of the ground shooting portion is selected (S104), the ground shooting portion to be erased is selected (S105), and only the selected ground shooting portion is erased from the recording medium (S106). Steps S105 and S106 are repeated for the whole ground shooting portion (S107).

  When a plurality of scenes or all scenes are selected (S101), and when all deletion of the scene including the ground shooting portion is selected (S108), all the selected scenes are deleted from the recording medium (S109). When deletion of only the ground shooting portion is selected (S110), only the ground shooting portion of the selected plurality of scenes is deleted from the recording medium (S111).
