Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera-integrated video recorder in which a television camera and a video recorder are integrated.

[0002]

2. Description of the Related Art Conventionally, a camera-integrated video recorder in which a television camera and a video recorder are integrated has been widely used.

[0003]

In a conventional camera-integrated video recorder, only one image can be shot / recorded, and a plurality of images cannot be shot / recorded at the same time.

Therefore, it is a primary object of the present invention to provide a camera-integrated video recorder capable of shooting and recording a plurality of images simultaneously and in synchronization with each other.

[0005]

In order to achieve the above object, the present invention is configured as follows in a camera-integrated video recorder. That is, this camera-integrated video recorder has a main image capturing device for capturing a main image, a main recording device for recording the main image captured by the main image capturing device, and a main image capturing direction different from that of the main image capturing device. A sub-photographer for photographing the sub-picture, a sub-recorder for recording the sub-picture photographed by the sub-photographer, and a time code supply device for supplying the same photographing time code to the sub-photographer and the main photographer Is equipped with.

Thus, according to the present invention, a plurality of images can be photographed and recorded simultaneously and in synchronization with each other.

Here, the main photographing device and the sub-photographing device may be any type as long as they are television cameras. Furthermore, the sub-photographer is not limited to the television camera that shoots an image. The sub-camera may be a still camera that captures still images. The main recording device and the sub recording device may be ones that record an image using a debiotape.
The main recording device and the sub recording device may be a recording device such as a disk-shaped recording medium or a hard disk device that records video in a non-linear manner. However, it is preferable that the main recorder continuously records the main image for a long time.
Therefore, the main recorder is preferably composed of a recording device having a large recording capacity (for example, a video tape recording device). On the other hand, there is a case where continuous recording is not required in the sub recorder (still picture recording as a direct example). In this case, the sub recorder may be composed of a recording device having a small recording capacity. As a recording device having a small recording capacity, a recording device using a recording medium using a semiconductor memory (for example, a memory card) can be considered.

Further, in the present invention, it is preferable that a first display device for displaying the main image and a second display device for displaying the sub image are further provided. Thereby, the main image and the sub image can be visually checked individually.

Further, the present invention further comprises a video synthesizer for synthesizing the main video and the sub-video into an arbitrary video form, and a display for displaying the synthetic video synthesized by the video synthesizer. Is preferred. Accordingly, the main image and the sub-image can be visually confirmed at the same time and in synchronization with each other by a visual operation on one display device.

Further, in the present invention, it is preferable that the photographing direction of the sub-photographer is set to a direction in which a photographer operating the camera-integrated video recorder can photograph. As a result, the posture (including facial expression) of the photographer during photographing can be recorded as a sub-picture. At this time, the posture (including facial expression) of the photographer at the time of shooting the main image can be recorded in a state of being synchronized with the main image.

Further, in the present invention, it is preferable to further include a photographing angle adjuster capable of arbitrarily setting a relative relationship between a photographing direction of the sub photographing device and a photographing direction of the main photographing device. Thus, when shooting the main video, a video in any other direction different from the shooting direction of the main video can be recorded as the sub-video.

Further, according to the present invention, a detector for detecting an image change in the sub-picture, and a recording controller for controlling a recording operation of the sub-picture with respect to the sub-recorder based on a detection result of the detector. Is preferably further provided. As a result, the sub-picture can be recorded only when the sub-picture being photographed changes. By performing such selective recording processing on the sub-picture, it is possible to reduce the recording amount of the sub-picture.

It is preferable to reduce the recording amount of the sub-picture for the following reason. In the present invention, the sub-picture can be positioned as additional information supplementing the main picture.
Here, the additional information refers to information that supplements the information recorded in the main video and further enriches the content. When such positioning is given to the sub-picture, it is preferable that the recording amount of the sub-picture is set to a necessary minimum. By doing so, it becomes easy to partially extract the required sub-image. The amount of information in the sub-picture will not unnecessarily increase. This is the main reason why it is preferable to reduce the recording amount of sub-pictures.

In order to perform partial recording of the sub-picture, the recording controller performs control to selectively record the sub-picture before and after the detector detects a picture change in the sub-picture. Is more preferable.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a camera-integrated video recorder according to an embodiment of the present invention, and FIG. 2 is an external perspective view thereof.

This camera-integrated video recorder (hereinafter,
The movie camera is called a main camera 1 and a sub camera 2.
A time code supplier 3, an image synthesizer 4, a main recording / reproducing device 5, a sub recording / reproducing device 6, a switching device 7, a first display device 8, and a second display device 9, A detector 10 and a recording controller 11 are provided.

The main photographing device 1 is a photographing device for photographing a main image in this movie camera. The main photographing device 1 includes a main photographing lens unit 1a (see FIG. 2). The lens of the main photographing lens unit 1a is oriented along the main video photographing direction α of the movie camera.

The sub-photographer 2 is a photographer for photographing a sub-picture in this movie camera. The sub-photographer 2 includes a sub-photographing lens unit 2a. The lens of the sub-photographing lens unit 2a is oriented along the sub-picture photographing direction β of the movie camera. The arrangement position of the sub-photographing lens unit 2a will be described later. The sub video shooting direction β is provided along a direction different from the main video shooting direction α.

The time code supplying device 3 supplies the same photographing time code to the main photographing device 1 and the sub photographing device 2.

The main video data generated by the main camera 1 is
It is output to the video synthesizer 4, the main recording / reproducing device 5, and the switching device 7. The sub-picture data generated by the sub-photographer 2 is output to the video synthesizer 4, the switch 7 and the sub-recorder / reproducer 6,
It is also output to the detector 10.

The video synthesizer 4 synthesizes the main video data and the sub video data to generate synthetic video data. The image synthesizer 4 outputs the generated combined image data to the switch 7.

The main recording / reproducing device 5 records / reproduces main video data. In this movie camera, the main video data is a set of video data that is continuously recorded. Therefore, the recording medium used in the main recording / reproducing device 5 requires a large recording capacity. Therefore, the main recording / reproducing device 5 is composed of a recording / reproducing device using a video tape VT having a large recording capacity as a recording medium.

The sub-recording / reproducing device 6 records / reproduces the data of the sub-picture taken by the sub-photographing device 2. In this movie camera, the sub-picture data becomes picture data recorded intermittently and in pieces. Therefore, the recording medium used in the sub-recording / reproducing device 6 does not require such a large recording capacity.
Therefore, the sub-recording / reproducing device 6 is composed of a recording / reproducing device using a memory card MC, which has a relatively small recording capacity but is easily miniaturized, as a recording medium.

The switch 7 controls the switching of the video data supplied to the first display 8 and the second display 9. The main video data from the main camera 1, the sub video data from the sub camera 2, and the composite video data from the video synthesizer 4 are input to the switcher 7, respectively. The switch 7 selects the main video data, the sub video data, and the composite video data input in this way and outputs them to the first display 8 and the second display 9.

The first display 8 is composed of the viewfinder of this movie camera. The second display 9 is composed of a small liquid crystal display attached to this movie camera.

The detector 10 detects the presence or absence of image change in the image forming the sub-image data. The presence / absence of video change is determined by a general-purpose image recognition technique.

The recording controller 11 controls the recording operation of the sub recording / reproducing device 6 based on the detection result of the detector 10.

Next, the mounting positions of the main photographing lens unit 1a, the sub photographing lens unit 2a, the first display unit 8 and the second display unit 9 will be described with reference to FIG.

The main photographing lens section 1a is provided at the tip of the main body section 20 of this movie camera. The first display 8 which is a viewfinder is provided at the rear end of the main body 20. The first display 8 has its display surface on the main body 2
0 is arranged in the rear direction. The second display 9 composed of a small liquid crystal display device is attached to the side surface of the main body portion 20 via an attachment link 21. Mounting link 21
Attaches the second indicator 9 to the main body 21 in the following manner. -The display surface 9a of the second indicator 9 is the main body 2
The attachment link 21 attaches the second indicator 9 to the main body 20 so that it can be opened and closed with respect to zero. When the display surface 9a is opened, the attachment link 21 attaches the second display 9 to the main body portion 20 so that the display surface 9a faces the rearward direction of the main body portion 20 (the direction facing the photographer). There is. When the display surface 9a is opened, the display surface 9a is rotatable along the horizontal axis and the vertical axis of the main body 20,
The attachment link 21 attaches the second indicator 9 to the body portion 20.

Sub-photographing lens section 2a constituting the sub-photographer 2
With respect to the main body unit 20 in the sub-picture shooting direction β.
It is attached toward the rear of 0. In the present embodiment, as an example, the sub-image lens unit 2a is attached to the lower end of the display surface 9a of the second display unit 9. When the second display 9 is opened and the display surface 9a thereof faces the rear direction of the main body unit 20, the sub-picture lens unit 2a (sub-photographing direction β) also moves in the rear direction of the main body unit 20 (facing the photographer). Direction).

The operation of this movie camera will be described below. When the photographer performs a shooting operation of the movie camera, the photographer turns his / her face to the first display unit 8 or the second display unit 9. This is an action to be performed in order to make it possible to visually confirm the object to be photographed on the display units 8 and 9. In any configuration (when viewing the first display unit 8 and when viewing the second display unit 9) in the configuration in which the sub-photographing lens unit 2a is provided in the second display unit 9, first The operation of opening the display unit 8 of No. 2 is performed. This is an operation performed in order to set the sub-picture shooting direction β to a direction in which the photographer's appearance can be taken. However, when the sub-photographing lens unit 2a is not provided in the second display unit 9 and the first display unit 8 is viewed, it is not necessary to open the second display unit 9.

In this state, the photographing operation is started. Then,
The main photographing device 1 and the sub photographing device 2 start photographing at the same time. At this time, the photographer arbitrarily selects a subject to be photographed.
Therefore, the main image data generated by the main image capturing device 1 is image data obtained by capturing the image capturing target arbitrarily selected by the photographer. On the other hand, in the state where the second display 9 is opened, the sub-photographing lens unit 2a is attached with the lens facing the rear direction of the main body unit 20. Therefore, the sub-picture data generated by the sub-photographer 2 is video data obtained by photographing the photographer's appearance (for example, facial expression) facing the sub-photographing lens unit 2a.

Here, in the main photographing device 1 and the sub-photographing device 2,
The same time code is supplied from the time code supply device 3. Therefore, the main image capturing device 1 and the sub image capturing device 2 generate video data with the same time code.

The main photographing device 1 outputs the generated main video data to the main recording / reproducing device 5 and the video synthesizing device 4. The sub-photographer 2 uses the generated sub-picture data to record the sub-recording / reproducing device 6 and the video synthesizer
And output to. The main recording / reproducing device 5 records the input main video data on the video tape VT. The sub recording / reproducing device 6 records the input sub video data in the memory card MC.
The same time code is recorded on the main video data recorded on the video tape VT and the sub video data recorded on the memory card MC as described above.

The video synthesizer 4 synthesizes the input main / sub video data. The image synthesizing form is registered in the image synthesizing unit 4 in advance. As a combination form, as shown in FIG. 3A, an image form in which a sub-image 101 is fitted to one corner (the lower right corner in the figure) of the main image 100 is considered. In addition, as shown in FIG.
The image form in which 00 and the sub-image 101 are arranged in parallel on the left and right is also considered as a combined form. Since a method of synthesizing images is well known, detailed description thereof will be omitted here.

The combined image data combined by the image combiner 4 is output to the switch 7. The main image data generated by the main image capturing device 1 and the sub image data generated by the sub image capturing device 2 are simultaneously input to the switching device 7. The switch 7 controls the output destination of the input video data based on the photographer's instruction. The instruction of the photographer is given in advance via an operation unit (not shown) provided in the movie camera, and is also given at any time via the operation unit during the photographing operation.

The control of the output destination of the video data is, for example, as follows. The main video data is output to the first display 8 and the sub video data is output to the second display 9. -Main video data is output to the first display 8 and no video data is output to the second display 9. Output sub video data to the first display 8 and main video data to the second display 9. -No video data is output to the first display 8, and main video data is output to the second display 9. -Sub-picture data is output to the first display 8 and no picture data is output to the second display 9. -No image data is output to the first display 8, and sub-image data is output to the second display 9. The composite video data is output to the first display 8 and the main video data is output to the second display 9. The composite video data is output to the first display 8 and no video data is output to the second display 9. The main video data is output to the first display 8 and the composite video data is output to the second display 9. -No video data is output to the first display 8, and composite video data is output to the second display 9. The composite video data is output to the first display 8 and the sub video data is output to the second display 9. -Sub-video data is output to the first display 8 and composite video data is output to the second display 9.

The first and second display devices 8 and 9 convert the main video data, the sub video data or the composite video data selectively supplied through the switching device 7 into a video and display the video.

In this way, the first and second main image data, the sub-image data and the composite image data are selectively displayed.
The photographer visually observes the display surfaces of the display devices 8 and 9 of FIG. Thereby, the photographer can photograph the photographing target while grasping the mutual relationship between the main image 100 and the sub-image 101. In the present embodiment, the sub-image 101 is a photograph of the appearance (most preferably, facial expression) of the photographer himself. Therefore, the photographer shoots the main image 100 (shooting target) while checking the sub-image 101 that reflects the appearance change (expression change) of the photographer himself at the time of shooting. Therefore, the shooting operation itself will have an unprecedented entertainment value.

The reproduction of the main video data and the sub video data thus photographed is carried out as follows. Note that, here, a case where the main video data and the sub video data are reproduced by the movie camera of the present embodiment will be described. However, the functions of the main recording / reproducing device 5 (particularly the reproducing function), the sub recording / reproducing device 6 (particularly the reproducing function), the video synthesizer 7, the first display 8 and the second display 9 of the present embodiment are Equivalent reproduction can be performed by any video reproducing device having an equivalent function.

In each of the main recording / reproducing device 5 and the sub-recording / reproducing device 6, the video tape VT and the memory card MC which are simultaneously recorded are loaded. In this state, a reproduction switch (not shown) is operated. Then, the main recording / reproducing device 5 reproduces the main video data of the video tape VT from the tape position at the reproduction position at that time. Video tape V
When the reproduction of T is started, the main recording / reproducing device 5 outputs the time code at the reproduction position of the video tape VT read by the reproduction to the sub-recording / reproducing device 6. The sub recording / reproducing device 6 reproduces the sub video data of the memory card MC from the same time code position as the supplied time code.

The main and sub recording / reproducing devices 5 and 6 output the reproduced main and sub video data to the video synthesizing device 4 and the switching device 7. The video synthesizer 4 synthesizes the supplied main and sub video data and outputs it to the switch 7. Since the image composition is similar to that described above, the description thereof is omitted here. Here, the same time code is attached to the sub-picture data and the main picture data at the time of recording. Further, the sub-picture data and the main picture data are simultaneously read out in synchronization with the time code. Therefore, the reproduction timings of the main and sub-picture data to be reproduced coincide with each other. Furthermore, the reproduction timings of the main and sub video data on the composite video data also match each other.

The switch 7 controls the output destination of the reproduced video data based on the instruction of the photographer. The first and second display devices 8 and 9 convert the / reproduction main video data, the reproduction sub-video data, and the composite video data, which are selectively supplied through the switching device 7, into a video image and display it.

In this way, the photographer views the display surfaces of the first and second display devices 8 and 9 for selectively displaying the reproduced main video data, the reproduced sub video data, and the reproduced composite video data. As a result, the photographer can see the main image 100 and the sub-image 10
It is possible to judge the performance of the main image 100 while grasping the mutual relationship with the main image 1. In the present embodiment, the sub-image 101 is the photographer's own appearance (most preferably a facial expression).
Will be taken. Therefore, the photographer checks and appreciates the main image 100 (object to be photographed) while confirming the sub-image 101 that reflects the appearance change (expression change) of the photographer himself at the time of photographing. As a result, when playing back and viewing the recorded video, an added value that has not existed in the past (for example, attachment of additional information or addition of new entertainment) is given.

The above description of the operation of the movie camera of the present invention is an explanation of the basic operation of the movie camera of the present invention. In the basic operation, the detector 10 and the recording controller 1
The function of 1 is stopped. Next, the operation of the movie camera of the present invention when the detector 10 and the recording controller 11 are made to function will be described.

The sub video data recorded by the sub recording / reproducing device 6 can be positioned as additional information supplementing the main video data. Here, the additional information refers to information that supplements the information recorded in the main video data to further enrich the content. When such positioning is given to the sub-picture data, it is preferable to keep the recording amount of the sub-picture data to the minimum necessary. This makes it easy to partially extract the necessary sub-picture data. The information amount of the sub-picture data will not unnecessarily increase. Further, in order to reduce the size and weight of the movie camera, it is preferable to reduce the recording capacity of the sub recording / reproducing device 6.
In consideration of these points, the sub-recording / reproducing device 6 is composed of a recording / reproducing device using the memory card MC as a recording medium. Further, the sub recording / reproducing device 6 operates as follows based on the operations of the detector 10 and the recording controller 11 in order to minimize the recording capacity during recording.

First, the basic concept of suppressing the recording capacity in the sub recording / reproducing device 6 will be described. In the present invention, as described above, the sub-picture data is positioned as additional information supplementing the main picture data. Further, in the present embodiment, the sub-picture data is used as the photographer's appearance (especially facial expression) information at the time of photographing. Therefore, during the generation of the main video data, it is not necessary to constantly record the sub-video data as such information. The sub-picture data may be selectively recorded when the appearance (expression) of the photographer changes at the time of photographing. This is due to the following reasons.

The emotion of the photographer during photographing changes according to the movement of the subject. The emotional change of the photographer is its appearance (expression)
Remarkably appears in. If a change in the appearance (expression) of the photographer is recorded as sub-picture data, great value is produced as information that supplements the main picture data. Specifically, consider a case where the appearance (expression) of a photographer (parent) when photographing his / her child as a photographing target is recorded as sub-picture data.
In this case, changes in the appearance (expression) of the photographer (parent) that changes with the motion of the subject (child) of the main image data are recorded as the sub image data. In this case, the sub-picture data (parent's appearance (expression)) is the main picture data (child's movement)
It will be of great value as auxiliary data for.

However, the emotional change of the photographer does not always occur. The appearance (expression) of the photographer changes only when a relatively large movement occurs in the movement of the subject of the main image data. That is, the appearance (expression) of the photographer changes intermittently. Even if the appearance (expression) of the photographer having such characteristics is continuously recorded as sub-picture data, the recording capacity is wasted. In this case, the sub-picture data may be selectively recorded before and after the appearance (expression) of the photographer changes.

Therefore, in the movie camera of this embodiment, an operation of detecting a video change of the sub video data is performed.
Then, the recording of the sub-picture data is controlled based on the detection result. This will be described below.

The sub-picture data generated by the sub-photographer 2 is output to the detector 10. The detector 10 determines whether or not there is a movement (change) in the subject to be captured of the sub-image 101 (in this case, the appearance (expression) of the photographer) in the input sub-image data over time. Specifically, for example,
The movement (change) of the sub-picture data is detected as follows.

Sub-photographer The sub-photographing lens section 2a is provided at the lower end of the second display 9. Sub-picture 10 at this position
When 1 is photographed, the appearance (face) of the photographer who is the photographing target of the sub-picture 101 is arranged at a fixed position on the screen. In the detector 10, as shown in FIGS. 4 (a) and 4 (b), a region on the screen of the input sub-image data in which the shooting target of the sub-image 101 is predicted to be set is preset as a target arrangement region γ. I'll do it. FIG. 4 (a),
(B) shows a display example of the sub-picture 101. In addition,
Of course, in the sub-photographing lens unit 2a, the angle of view is set so that the appearance (expression) of the photographer who is the photographing target of the sub-picture 101 falls within the screen.

When the sub-picture data is input, the detector 10 detects whether or not there is a movement (change) in the picture located in the set target arrangement area γ by using the image recognition technique. Since the image recognition technology is well known, its description is omitted here. Specifically, in the sub-image 101 in FIG. 4A, the subject (photographer himself) of the sub-image 101 is relatively expressionless. However, FIG.
In the sub-picture 101 in (b), the object to be photographed is laughing greatly, and changes in the facial expression (shape changes of eyes, eyebrows, and mouth) are detected as video changes.

Here, when the movie camera is used for hand-held photographing, so-called hand-shake occurs during photographing. In this case, if a large camera shake occurs, the position of the shooting target of the sub-picture 101 in the sub-picture data will largely change in the screen. Then, the detection accuracy of the image change is lowered. In such a case, a camera shake correction mechanism (which may be an optical camera shake correction mechanism or a digital data camera shake correction mechanism) may be provided to suppress the position variation of the imaging target due to camera shake. Since the camera shake correction mechanism is a known technique, its description is omitted here.

The movement (change) of the subject of the sub-picture data detected in this way is output from the detector 10 to the recording controller 11. The detection results are a detection result indicating that there is a motion in the imaging target of the sub-picture data and a detection result indicating that there is no motion (hereinafter, abbreviated as "motion" and "no motion"). The recording controller 11 performs the following recording control on the sub recording / reproducing device 6 based on the detection result of the detector 10.

First, a basic recording operation of the sub recording / reproducing device 6 will be described. The sub-recording / reproducing device 6 constantly writes sub-picture data in the memory card MC. Further, the sub-recording / reproducing device 6 sequentially updates the recorded contents from the oldest one when the recording capacity is full. That is, the sub-recording / reproducing device 6 stores the memory card MC in a FIFO (First InFi
rst out) functioning as memory. Therefore, the sub-recording / reproducing device 6 continuously records the latest sub-picture data on the memory card MC while constantly updating it.

In some cases, due to the functional limitation of the writing means for the memory card MC, the writing speed for the memory card MC may not be as high as the photographing speed. In that case, a buffer memory may be provided in front of the signal transmission direction of the memory card MC. By doing so, after writing to the buffer memory at the same speed as the shooting speed, it is possible to slowly rewrite from the buffer memory to the memory card MC.

The recording controller 11 instructs the recording / reproducing operation to be continued during the period when the detection result input from the detector 10 is "no motion". Then, when the detection result is "moving", the following recording control is performed. That is, the sub-picture data at the time when it is determined that there is "movement" is set as the non-updatable data,
The sub-recording / reproducing device 6 is instructed to be stored separately.

The amount of data to be stored as non-updatable data is preset based on the recording capacity of the memory card MC. For example, the amount of stored data such as data for one still image, data for 5 seconds of video, and data for 10 seconds of video is set in advance. In addition, the recording start point of non-updatable data is set. In this case, since the sub recording / reproducing device 6 causes the memory card MC to function as a FIFO (First In First Out) memory, the recording start point of the non-updatable data can be arbitrarily set. For example, the detector 10
It is possible to record the sub-picture data of an arbitrary period with the recording start point at the time when it is determined that there is "movement" as non-updatable data by the sub-recording / reproducing device 6. Furthermore, it is also possible to record sub-picture data of an arbitrary period with a recording start point at a time point that is an arbitrary time (for example, several seconds) back from the time point when it is determined that there is "movement" as non-updatable data. As described above, in the sub recording / reproducing device 6, the “moving” is detected by the detector 10
It is possible to record the non-updatable data by using the time point that is traced back from the time point determined by the above as the recording start point.

The recording controller 11 can suppress the recording amount of the sub-picture data recorded in the memory card MC to the necessary minimum by performing the recording control described above on the sub-recording / reproducing device 6. In addition, at that time, it is possible to record the necessary sub-picture data (data at the time when there is a movement in the shooting target of the sub-picture data) without missing.

FIG. 5 shows a modification of the sub-photographing lens section 2a '. In the sub-photographing lens unit 2a ′ shown in FIG. 5, a mounting mechanism 24 having a vertical rotation shaft 22 and a horizontal rotation shaft 23.
The lens portion 2a ′ is attached to the main body portion 20 via the. In FIG. 5, the sub-photographing lens unit 2a ′ is attached to the upper end of the second display unit 9 as an example of the attaching position. In this modification, the vertical rotary shaft 22 and the horizontal rotary shaft 23 are
The mounting mechanism 24 including and corresponds to the photographing angle adjuster in the claims.

In the modified example, the sub-photographing lens section 2a '.
Can direct the sub-image shooting direction β to an arbitrary direction of approximately 360 degrees. Therefore, the sub-photographer 2 can photograph a video image in an arbitrary direction and generate sub-picture data.
