Abstract

PROBLEM TO BE SOLVED: To prevent missing of photographed part from being generated in the case that a photographing area is moved to conduct photographing so as to obtain a single still image as a whole in a camcorder. SOLUTION: An area wider than a field image photographed by a CCD is set as a still image area 100. A camera is moved longitudinally and laterally to photograph all over the area. The photographed area is stored in a frame memory and displayed on a finder as an already photographed image 103. The area not yet photographed is displayed in blue as an unphotographed area 102. A newest image is displayed on a dynamic image area 101. In the case that a duplication rate between field images of the area 101 and of the already photographed image area 103 is smaller than a minimum duplication rate, the part is displayed as a missing area 102. When the area 101 protrudes from the area 100, the area is automatically magnified.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an image processing system and a camera-integrated video recorder capable of obtaining a still image having more pixels than the number of pixels of a CCD.

[0002]

2. Description of the Related Art In a digital camera-integrated video tape recorder, for example, a CCD is used as an image pickup device, and a video signal obtained by shooting a moving image is recorded on a magnetic tape as digital video data. In such a camera-integrated video tape recorder, it is conceivable to record a plurality of field images (or frame images) while slowly moving the shooting area vertically and horizontally, and combine the recorded plurality of field images. As a result, it is possible to obtain a still image having a larger area range than an image of one field at the time of capturing a moving image.

[0003] That is, recording is performed by gradually moving the photographing area so that a field image can be obtained continuously from the photographing start point. Then, for the recorded field image, the overlapping portion of the field image that is positionally adjacent is extracted, and by performing a predetermined operation on the overlapping portion, the respective field images are seamlessly combined, Image processing is performed to obtain one still image as a whole. Such image processing is performed by software processing by a personal computer, for example.

[0004]

In order to obtain a larger still image, it is necessary to change the direction many times in the vertical and horizontal directions. For example, shooting is performed while gradually shifting the shooting area to the right from the shooting start position, and when the shooting width reaches a desired width, the shooting area is moved further upward so as to overlap the already shot area. Continue to move to the left. When the left end of the shooting area reaches the shooting start point, it is further moved upward. This operation is repeated.

[0005] In a conventional video tape recorder with a built-in camera, an area wider than an area that can be photographed by a lens system cannot be displayed on a viewfinder. Further, the trajectory of the photographing area is not displayed on the viewfinder. Therefore, when such photographing is performed, there is a problem in that field images do not overlap and a part of photographing omission may occur. If a part of the photographing omission occurs, a problem occurs when a single still image is synthesized as a whole.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an image processing system and a camera-integrated type in which a photographing region is moved so as to obtain a single still image as a whole and a photographing omission portion does not occur. It is to provide a video recorder.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a recording medium in which a plurality of field images or frame images are continuously photographed such that photographing areas have overlapping portions. And an image processing means for reproducing a plurality of field images or frame images from a recording medium and synthesizing one still image based on an overlapped portion.

[0008] In addition, in order to solve the above-mentioned problems, the present invention provides a method of synthesizing a single still image from a plurality of field images or frame images at the time of reproduction. In a camera-integrated video recorder configured to continuously shoot frame images such that shooting regions overlap, shooting means for outputting a field image or a frame image having a first shooting region, and a field image or a frame image Means for recording an image on a recording medium, a photographing area setting means for setting a second photographing area wider than the first photographing area, and displaying a field image or a frame image on a display area in parallel with photographing by the photographing means. Monitoring means and displaying the entire second photographing area on the display area;
A display means for reducing the field image or the frame image in accordance with the ratio of the size of the first and second imaging regions to display them on the display region, and when the first imaging region moves during imaging, In parallel with the movement, there is provided combining means for seamlessly combining the field image or the frame image before the movement and the field image or the frame image after the movement, and the combined image is displayed on the display means. Camera-integrated video recorder.

As described above, according to the present invention, image data that is continuously photographed and recorded is reproduced such that fields overlap at the time of photographing, and one still image is synthesized based on the overlapped portion. Therefore, it is possible to obtain a still image having a larger size composed of more pixels than the field image.

In the present invention, at the time of photographing, a second photographing area larger than the first photographing area corresponding to the field image (or frame image) is displayed on the monitor means, and the field images are displayed on the first and second photographing areas. The image is reduced and displayed on the monitor means in accordance with the ratio of the size of the area, and when the first imaging area moves during imaging, the field image before the movement and the field image after the movement are seamlessly combined and the monitor means Is displayed, it is possible to know an area that has already been photographed with respect to the second photographing area, and it is possible to perform photographing without omission when synthesizing a still image.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below. According to the present invention, a wider area than an image area of one field by moving image shooting is displayed on the viewfinder, and the viewfinder is
During photographing, an unphotographed area where photographing is not performed and an already photographed area that has already been photographed are displayed separately. Then, by reproducing the captured and recorded image and performing predetermined image processing on the reproduced image data, the image data composed of a plurality of fields is synthesized and
Obtain still images.

In the following description, a shooting area defined by the number of pixels of a CCD and obtained by, for example, normal moving image shooting is referred to as a moving image area. In addition, capturing a wider area than the moving image area to obtain one still image as a whole is referred to as multi-pixel still image capturing.

In this embodiment, in order for the user to control the multi-pixel still image shooting, a mode for performing a multi-pixel still image shooting and a mode for performing a normal moving image shooting for a camera-integrated video tape recorder are described. Mode switching key to switch between and start / stop multi-pixel still image shooting
Various keys such as a start / stop key for instructing termination, a display switching key for switching between moving image display and whole display during multi-pixel still image shooting, and a setting key for a shooting range and a start position for multi-pixel still image shooting A setting key is provided.

FIGS. 1 to 8 show an example of a display in a viewfinder of a video tape recorder integrated with a camera according to the present invention, and a multi-pixel still image shooting according to this embodiment will be schematically described. First, the shooting mode of the camera-integrated video tape recorder is set to the multi-pixel still image shooting mode. Before pressing the start key, a size, a minimum overlap ratio, and a shooting start position are set by a predetermined method. In this example, the size of the target still image is set to three times and twice the width of the moving image area, and the shooting start position of the multi-pixel still image shooting is set at the center of the 3 × 2 times vertical and horizontal range. I do.

There are various methods for setting the size. In this example, the subject is regarded as a plane, and the size of the target still image is set by giving vertical and horizontal magnifications. Further, the subject can be regarded as being inside the cylindrical surface, and the horizontal angle and the vertical magnification can be given. For example, the width is set to 90 ° and the height to three times. Further, the subject can be regarded as being inside the spherical surface, and the longitude and the latitude can be given. For example, the horizontal width is set to 90 ° and the vertical width is set to 60 °. Still further, the size of a still image can be specifically set by a camera. For example, the upper left setting key is pressed toward the upper left corner of the range where the camera wants to shoot, and then the lower right setting key is pressed toward the lower right corner of the shooting range.

Further, the setting of the photographing start position is not limited to the above-mentioned example set at the center. For example, a shooting start position can be set at the upper left corner and the upper right corner. When the size setting is set at the upper left corner and the lower right corner as described above, setting the shooting start position at the upper right corner enables more natural multi-pixel still image shooting.

Note that the minimum overlap ratio is 2
It is a ratio that needs to overlap each other in one moving image region, and is represented by an area ratio of the moving image region. The lower limit of the minimum overlap ratio is finally determined by software that performs image processing. In this example, the minimum overlap rate is set as 30%.

When the camera is pointed at the subject and the view finder is viewed, a still image area 100 corresponding to the aspect ratio of the set size is displayed as shown in FIG. Then, with respect to the still image area 100, the moving image area 101 captured by the CCD is reduced according to the set size, and displayed at the center corresponding to the shooting start position. The periphery of the image is, for example, an unphotographed area 102 filled with blue. In this state, if the direction of the camera is changed without pressing the start key, only the display content of the center moving image area 101 changes.

When the start key is pressed while facing the center of the subject to be photographed, photographing is started. The photographed image data is compression-encoded using a motion vector obtained by detecting a motion in a predetermined method and a DCT (Discrete Cosine Transform), and is recorded on a recording medium such as a magnetic tape. At the same time, the photographed image data is stored in a frame memory for performing predetermined image processing.
Note that the signal processing related to the photographing will be described later. By holding down the start key, multi-pixel still image shooting is continued.

Here, the camera is slowly turned to the right to move the shooting area. Then, the moving image area 101 moves within the still image area 100 as shown continuously in FIGS. 2 and 3. The image data of the moving image area 101 is stored in the frame memory as it moves, and is compression-coded and recorded on the magnetic tape. The previously captured image data is read from the frame memory and the captured image 10
3 is displayed in the still image area 100. In this way, the image captured even once by the CCD is stored in the still image plane. Unphotographed area 1 where no photography has been made
02 is still displayed in blue. In addition, the unphotographed area 10
The display of 2 is not limited to blue, but may be another color.

The storage of image data in the frame memory is performed by mixing data of overlapping portions of moving image areas whose photographing areas are adjacent to each other. This mixing is performed by calculation based on parameters that can be set based on a predetermined method. If this parameter is, for example, α such that 0 ≦ α ≦ 1, they are mixed in a ratio of α: 1−α. When α = 0, the overlapping portion is replaced with the latest data. When α = 1, only the first data is valid in the overlapping portion. Also, when 0 <α <1, mixing is performed such that a moving part in the overlapping part gradually disappears.

By mixing and storing data in this way, an image that is seamlessly combined in real time can be displayed in the viewfinder. The setting of the parameter α is performed, for example, by a predetermined key operation provided on a camera-integrated video tape recorder.

Further, the overlapping portion of the moving image area can be obtained based on the result of the motion detection performed at the time of the above-described compression encoding. By storing the result of the motion detection for each field, it is possible to know the positional relationship between the moving image regions photographed temporally apart from each other, and thereby to know the overlapping relationship between these moving image regions. Can be.

Subsequently, the camera is slowly moved in the vertical and horizontal directions until the non-photographed area 102 disappears from the viewfinder display. FIG. 4 shows an example in which the camera is turned upward from the state shown in FIG. 3. When the camera is further moved to the left from this state, the display on the viewfinder becomes as shown in FIG.

By the way, while the camera is slowly moving sideways, a clearly sufficient overlapping area is secured for the horizontally adjacent images. However, when moving upward and to the left as described above with reference to FIGS. 4 and 5, for example, a sufficient overlapping area may not be obtained in the vertically adjacent field images. This example is shown in FIG.

In order to seamlessly combine still images later, it is necessary to shoot images such that the overlap ratio is equal to or greater than the minimum overlap ratio (30% in this example). Current movie area 10
A captured image 103, which is a captured still image, exists around 1 and between the moving image area 101 and the captured image 103,
When the set minimum overlap rate cannot be ensured, the unphotographed area 102 is displayed for the insufficiently overlapped portion 104 as shown in FIG. In the example of FIG. 6, the minimum overlap rate is secured for the horizontal field, but is not secured for the vertical field. The insufficiently overlapped portion 104 that is not secured is displayed as the unphotographed area 102.

On the other hand, during shooting, 3 ×
Sometimes I want to double the size. For example, as shown in FIG. 7, a predetermined amount (for example, half) of the moving image area 101
When the above is outside the still image area 100, the image size is automatically changed to 4 × 2 so that the moving image area 105 which is outside is displayed, and the entire image is further reduced, as shown in FIG. The still image area 100 'is displayed on the screen.

The processing when the moving image area 101 is out of the still image area 100 is not limited to this method. For example, the display in the still image area 100 may be scrolled. That is, the entire display in the still image area 100 is scrolled downward to display the protruding moving image area 105. By doing so, the overall size can be increased while the reduction ratio of the image remains unchanged. However, in this case, the image initially displayed at the bottom of the screen disappears.

There are times when it is desired to view the moving image area 101 in detail during photographing. At this time, by switching the display mode to the moving image display mode by a predetermined operation, it is possible to display only the moving image region 101 in the viewfinder fully. For example, the display mode is switched by an operation of pressing the start key more strongly. By switching to this display, focus and iris can be adjusted. In order to return to the original whole display mode, for example, the start key is lightly pressed again.

In this manner, the blue unphotographed area 102
When is lost, the multi-pixel still image shooting is terminated. This is done, for example, by releasing the finger from the start key. Note that the non-photographed area 10 is
Even when 2 remains, multi-pixel still image shooting can be terminated. Even in this case, it is possible to combine already captured image data into one still image by software processing later.

FIGS. 9 and 10 show an example of the configuration of a camera-integrated video tape recorder for photographing such multi-pixel still images. In FIG. 9, the lens system 1
Can adjust optical systems such as iris, focus, and zoom. These adjustments are respectively controlled by the lens system drive circuit 16. This control is automatically performed based on the control of the system controller 18 described later. The adjustment of the optical system is not limited to this, and can be performed manually. Based on this control, control information is output from the lens system drive circuit 16. In this example,
The values of iris, focus, and zoom are output. This control information is supplied to the system controller 18.

An image of a subject is captured by a CCD (C
harge Coupled Device) 2. The illuminated subject image is converted into an electric signal by the CCD 2.
Although not shown, the CCD 2 has a predetermined signal processing circuit, and further converts the converted electric signal into digital image data and outputs it. The number of pixels of the CCD 2 corresponds to the image size of the moving image area. Image data is output from the CCD 2 in field units.

The image data from the CCD 2 is supplied to the compression encoding circuit 3 and also to the image processing circuit 17. The motion detection circuit 5 is connected to the compression encoding circuit 3. The motion detection circuit 5 obtains a motion vector by comparing image data of adjacent fields in a time series, and thereby performs motion detection of the image data. In the compression encoding circuit 3, the motion vector and the DCT (D
The compression coding of the supplied image data is performed using iscrete cosine transform).

The image data compressed and encoded by the compression encoding circuit 3 is supplied to a recording signal processing circuit 6. The recording signal processing circuit 6 includes an error correction encoding circuit, a recording equalizer, a recording amplifier, and the like. The image data is error-correction-coded by, for example, a product code using a Reed-Solomon code, and is converted into a signal suitable for recording via a recording equalizer and a recording amplifier.

In the recording signal processing circuit 6, together with the image data, the control information of the lens system output from the lens system driving circuit 16, that is, the iris value, focus value,
A zoom value is also provided. Further, the recording signal processing circuit 6 is supplied with the motion information based on the motion detection result from the motion detection circuit 5 described above. The control information and motion information of these lens systems are used as subcode data for the image data. The sub-code data is subjected to error correction encoding together with image data in an error correction encoding circuit.

The output of the recording signal processing circuit 6 is
And is recorded on the magnetic tape 8 by, for example, a helical scan method. Reproduction is performed by reading out a signal recorded on the magnetic tape 8 by the reproduction head 9 in the same manner. The read signal is supplied to the reproduction signal processing circuit 10.

Although a magnetic tape is used as a recording medium in this example, the present invention is not limited to this example. As long as the recording medium has an appropriate capacity and can record digital signals, other recording media can be used. For example, hard disk, magneto-optical disk, D
VD (Digital Versatile Disc) and semiconductor memory can be used as recording media.

The reproduction signal processing circuit 10 has a reproduction amplifier, a reproduction equalizer, an error correction circuit and the like. The signal supplied from the reproducing head 9 is converted into a signal suitable for digital processing via a reproducing amplifier and a reproducing equalizer, and supplied to an error correction circuit. The error correction code applied at the time of recording is decoded by the error correction circuit. The decoded data is supplied to the decompression circuit 12, where it is decompressed at the time of recording, and is output as reproduced image data. The output of the expansion circuit 12 is supplied to a terminal PB of the switch circuit 13.

Note that, from the output of the reproduction signal processing circuit 10,
Only the above-described subcode data can be extracted.
The extracted subcode data is led out to the data output terminal 11.

At the time of reproduction, the terminal PB is selected by the switch circuit 13 and reproduced image data is derived to the video output terminal 15. At the same time, the reproduced image data is supplied to the viewfinder 14. When the terminal PB is selected by the switch circuit 13 during reproduction, the reproduced image from the magnetic tape 8 is displayed on the viewfinder 1.
4 can be displayed. Further, by selecting the terminal PB with the switch circuit 13 at the time of recording, the image recorded on the magnetic tape 8 can be confirmed.

It should be noted that the system controller 18
U and a RAM, a ROM, etc., for controlling the operation of the camera-integrated video tape recorder. In the key input unit 19, the various setting keys described above are arranged. For example, a shooting mode switching key for switching between a mode for performing multi-pixel still image shooting and a mode for performing normal moving image shooting to the key input unit 19, and a start command for instructing start / end of multi-pixel still image shooting / Stop key,
A display switching key for switching between moving image display and whole display during multi-pixel still image shooting, and a key for setting a shooting range and a start position in multi-pixel still image shooting are provided. However, the present invention is not limited to this.
May be arranged. Setting information from these various setting keys is supplied from the key input unit 19 to the system controller 18 and stored in, for example, a RAM.

By the way, as described above, the image data output from the CCD 2 is supplied to the image processing circuit 17. The supplied image data is subjected to predetermined processing by the image processing circuit 17 and is supplied to the terminal REC of the switch circuit 13. At the time of recording, by selecting the terminal REC by the switch circuit 13, the captured image is displayed on the viewfinder 14.
Can be displayed.

Next, the processing in the image processing circuit 17 will be described. The image processing circuit 17 is connected to a frame memory 30 having a capacity corresponding to the number of pixels of the CCD 2, for example, twice the number of pixels of the CCD 2. The image signal output from the CCD 2 is supplied to the image processing circuit 17, and the motion detection result by the motion detection circuit 5, that is, the motion information is supplied. Further, a control signal based on various setting information set by the key input unit 19 is supplied from the system controller 18 to the image processing circuit 17. FIG.
The display of the viewfinder 14 as described with reference to FIG. 8 is realized by controlling the address of the frame memory 30 by the image processing circuit 17 under the control of the system controller 18.

For example, based on the size setting information set by the key input unit 19, the corresponding area of the frame memory 30 is filled with the initial value. The initial value is, for example, blue data indicating the unphotographed area 102. At this time, this region corresponds to the still image region 100 corresponding to the aspect ratio of the set size as shown in FIGS.

The C supplied to the image processing circuit 17
The image data from the CD 2 is reduced by, for example, thinning, and the moving image area 101 is formed. Frame memory 30
In, the data of the moving image area 101 is stored at an address based on the position information set by the start position setting key.

Further, the image processing circuit 17 includes a CCD 2
A motion detection result, that is, motion information, is supplied from the motion detection circuit 5 together with the image data output from. When the camera is moved to perform multi-pixel still image shooting, for example, a motion vector is output as the motion information. From the motion vector, the address of the image data in the frame memory 30 is obtained. That is, by accumulating the motion vectors, the locus of the movement of the moving image area 101 can be known.

At the same time, the image processing circuit 17 obtains an overlapping portion for each moving image area between the image data already photographed and stored in the frame memory 30 and the latest image data, and calculates an overlapping rate. . The image data of the overlapping portion is mixed at a ratio of α: 1−α based on the above-described preset parameter α, and
Is stored.

When the overlapping rate is less than the preset minimum overlapping rate in the overlapping portion, the portion is displayed in the viewfinder 14 as the insufficiently overlapping portion 104 as described above. The display of the insufficiently overlapped portion 104 is performed, for example, so that the data of the corresponding portion in the latest image data is not stored in the frame memory 30.
This is done by masking the data. In this case, the display is displayed in blue, in which the insufficiently overlapped portion 104 is stored in the frame memory 30 as an initial value.

In the example of FIG. 6, the moving of the camera is such that the moving image area 101 moves in the viewfinder 14 from left to right. Therefore, a sufficient overlapping portion can be obtained in the horizontal direction, but there is a portion with a small overlapping rate in the vertical direction because of a lack of temporal continuity. The overlap portion in the horizontal direction that satisfies the minimum overlap ratio is displayed in an overlapped manner, but the portion in the vertical direction that does not satisfy the minimum overlap ratio is displayed in blue as an insufficiently overlapped portion 104. You.

Also, based on the number of pixels of the CCD 2, the size setting information, the start position setting information, and the accumulated value of the motion vector, the latest image data is stored in the still image area 100.
It can be easily determined whether or not the display area extends beyond the display area. When it is determined that the latest image data protrudes from the still image area 100, the size setting information is appropriately changed so that the entire latest image data can be displayed in the still image area 100. At the same time, the reduction ratio of the image data 101 is also changed.

The latest image data is stored in the still image area 10.
Still image area 10 when it is determined that the
The scrolling of the display within 0 can be performed in the same manner. That is, the latest image data is stored in the still image area 100.
Is calculated, and the read address from the frame memory 30 is changed in accordance with the result. When performing scrolling, it is desirable that the frame memory 30 has a capacity of, for example, four or more pixels of the CCD 2.

As shown in FIG. 10, the camera-integrated video tape recorder may be provided with an angular acceleration sensor 20 composed of, for example, a gyro sensor. As the angular acceleration sensor 20, a sensor for a so-called camera shake prevention function, which is mounted on a camera-integrated video tape recorder, can be used. The output of the angular acceleration sensor 20 is integrated by an integrating circuit 21 to obtain motion information. In the mixing circuit 22, the motion information obtained by the angular acceleration sensor 20 and the motion information obtained from the motion detection circuit 5 are mixed and supplied to the image processing circuit 17.

By using the output of the angular acceleration sensor 20 as motion information, even when the motion detection circuit 5 does not work well, such as when photographing a flat subject or when photographing in the dark, The relative position of the image can be known, and the locus of movement of the moving image area 101 can be displayed in the viewfinder 14.

In the example shown in FIG. 10, the output from the motion detection circuit 5 and the output from the angular acceleration sensor 20 can be appropriately switched. That is, when a motion vector obtained by the motion detection circuit 5 cannot be correctly obtained in a flat portion of the subject or the like, the motion information based on the output of the angular acceleration sensor 20 is used, and
If the motion information can be obtained correctly, the output of the motion detection circuit 5 with higher accuracy is used. This switching is performed, for example, by giving a control signal from the system controller 18 to the mixing circuit 22.
Switching between manual and automatic is enabled.

The image data thus photographed and recorded is reproduced and supplied to a device for performing predetermined image processing, for example, a personal computer equipped with corresponding image processing software. In addition to the supply of the image data, the subcode data is output from the data output terminal 11. This subcode data is also supplied to the personal computer together with the image data. The supplied image data is subjected to a combining process by image processing software, and a seamless process is performed. At this time, by using the motion information and various photographing information such as zoom, iris, and focus supplied as the subcode data, it is possible to perform the synthesizing process with higher accuracy.

For example, the positional relationship of the image data of each field can be known based on the motion information included in the subcode data. As a result, an overlapping portion between the image data is obtained, and by performing a predetermined operation on the overlapping portion, the image data can be automatically synthesized. In addition, based on various information of the optical system such as zoom, iris, and focus included in the subcode data, image correction can be performed, and still image can be automatically synthesized after homogenizing each image data. It is said.

For example, based on the zoom information, the conversion of the image data into a plane or the conversion into a cylindrical surface or a spherical surface can be reliably performed. Further, the brightness correction of each image data can be reliably performed based on the iris information. Further, image data with different focus may be obtained even in the same photographing area. Based on the focus information, it is possible to select the clearest image data in pixel units, whereby an image with a deep depth of focus can be obtained.

[0058]

As described above, according to the present invention, during photographing, an unphotographed portion and a photographed portion are clearly distinguished and displayed in a viewfinder or an external monitor. Therefore, even when continuously capturing a larger area than the moving image area in order to obtain a larger still image, there is an effect that an unphotographed portion does not remain.

According to the present invention, control information of the optical system at the time of photographing and motion information of the field image are recorded together with the image data as subcode data. Therefore, when reproducing and synthesizing the recorded data, This has the effect that seamless processing can be performed with higher accuracy.
