Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image recording / reproducing apparatus which performs processing such as enlargement, reduction, slide, rotation and the like on an externally input image signal to reproduce the image signal.

[0002]

2. Description of the Related Art FIG. 11 is a block diagram of a conventional image recording / reproducing apparatus. In FIG. 11, received analog image data arriving from the outside is subjected to signal processing in an analog signal processing unit 2 and converted into a digital signal in an A / D conversion unit 3. Then, the image data converted into the digital signal is subjected to signal processing in the digital signal processing unit 4 and is recorded in the image recording unit 5 as digital image data.

When reproducing image data recorded in the image recording section 5, the image data recorded in the image recording section 5 is taken into the image reproducing section 6, and then converted into an analog signal by the D / A conversion section. Thereafter, the image is output to the external image display unit 9 or the output terminal 8, and the reproduced image is displayed on the image display unit 9.

The camera-integrated video tape recorder disclosed in Japanese Patent Laid-Open No. 5-244566 has an image enlargement magnification setting switch 18 and an image enlargement interpolator 19 for enlarging and displaying a reproduced image in addition to the functions of the conventional example. Are provided.

[0005] There are roughly three types of methods for taking in image data from the outside, a method of inputting from an attached camera (CCD 1), a method of receiving an external radio wave, and a method of already recording (recording) on another image recording medium. There is a method of taking in the image data obtained. When inputting from a camera, image data captured by the CCD 1 is captured. When receiving an external radio wave, the image signal data receiving unit 11 receives the analog image signal data 10 from the station.

Next, a method for recording / reproducing the above three types of image data taken from outside will be described. Mainly fixed video tape recorders for home use (hereinafter VTRs)
11) is connected to the television, and receives the external analog image data 10 with the image signal data receiving unit 11 (antenna) of the television as shown in the upper right dotted frame in FIG. The image is recorded in the image recording unit 5.
Thereafter, the image is reproduced and displayed through the image display unit 9 of the television.
The user can freely select which image data is to be recorded, and the recorded image can be reproduced and displayed at any time when desired.

The image reproducing section 6 has a function of replaying a scene particularly desired to be viewed in the recorded image (rewinding and reproducing functions), a function of stopping the reproduction screen (pause function), or a screen which is not desired to be viewed. There is a function for skipping over (fast forward function) and the like, and a very flexible playback method is possible. As described above, in the recording operation, the image data is recorded on an image recording medium such as a magnetic tape or a DVD, and the recorded image can be similarly reproduced and displayed on another VTR manufactured on the same basis. The image data in such an image recording medium is specially recorded by an expert, and may be sold or rented to a user in some cases. After purchasing or renting an image recording medium containing such image data, the user can use his / her own VTR.
It is possible to play with. By setting the purchased or rented image recording medium in the VTR, the above-described functions (rewinding, reproducing, fast-forwarding, and pausing functions) can be similarly realized.

On the other hand, a handy type V integrated with a camera
The TR has a form in which a camera (CCD1) for photographing a subject is added, as shown in the dotted frame on the upper left side of FIG. 11, and it is possible to photograph an image desired to be photographed using this camera. It is possible. At the image capturing stage, the subject can be freely enlarged / reduced and the subject moved (changed) by the enlargement / reduction (so-called zoom change) and display image movement (change) functions which are the attached functions of the VTR. In addition, by moving the camera, it is possible to capture an image from above, below, left and right or from behind (rotation of the image). When the recording function for the image being photographed is activated, the image data of the photographed image can be faithfully recorded on the image recording medium set in the image recording unit 5 of the VTR.

The image data recorded on these image recording media can be reproduced and displayed by setting it on a VTR having a reproducing function (for example, the above-mentioned fixed type VTR). Also, with a camera-integrated handy-type VTR with a playback function recently released, recorded image data can be played back and displayed on the spot. The playback function of the fixed type VTR and the handy type VTR has not only the function of faithfully reproducing the recorded screen on the spot, but also additional functions such as rewinding and fast-forwarding, as well as unnecessary images (image data). ) Has some editing functions such as cutting. In recent years, photographed image data is imported to a personal computer or the like, and the editing function of the personal computer can perform some editing on the image data.

In the "camera-integrated video tape recorder" described in Japanese Patent Application Laid-Open No. 5-244566, when reproducing image data recorded by the attached CCD 1, an image magnification setting switch 18 can be used to set an arbitrary screen to be enlarged and displayed. Are designated and the enlargement magnification is set, and the image enlargement interpolation unit 19 performs enlargement display for the setting. Although this has the disadvantage that the quality of the image is reduced, it is possible to realize an enlarged display of the reproduced image. In addition, by recording the image at a constant magnification, it is possible to select and reproduce either a normal image or an enlarged image at the above magnification. As a result, a high-quality enlarged image can be displayed in addition to the normal image.

[0011]

In a fixed type VTR used for homes, an image reproducing unit 6
Although a function of rewinding, fast-forwarding, pausing, and the like for a reproduced image and an editing function for a certain amount of image data are provided, an enlargement / reduction display function of an arbitrary part of the reproduced image or movement of a displayed image (slide) is provided. There is no one that has a function of displaying a non-displayed portion by / rotation. This has a problem in both the recording method of the image data from the outside or the received image data in the image recording unit 5 and the reproduction function of the VTR.

First, image data from the outside is used. Here, image data received by receiving radio waves from a station, image data already registered in an image recording medium, and the like are targeted. As the received image data, image signal data received from the image data receiving unit 11 (antenna) of the television is typical, and as the image data already registered in the image recording medium, a commercially available or rented recorded medium is used. Etc. They transmit or record only image data for displaying a fixed reproduced image.

Accordingly, since image data viewed from the top, bottom, left, right, or rear, or image data obtained by enlarging and displaying an arbitrary portion other than the image data normally reproduced is not transmitted or recorded, even if the image data is reproduced and displayed, it is inevitable. Only a fixed reproduction image can be displayed. Further, even if image data for enlarged / reduced display or image data for moving (slide) / rotating display of a display image is added to the transmitted or recorded image data in addition to the normal reproduced image data, An arbitrary 1 is provided to the image playback unit 6 as a VTR playback function.
Since a function such as display of an undisplayed portion by enlargement / reduction display of a portion or movement (slide) / rotation of a display image is not provided, only a fixed image can be displayed.

On the other hand, a handy-type camera-integrated VT
R can perform various shootings, such as displaying an undisplayed portion by enlarging / reducing the subject or moving (sliding) from the subject during shooting, or shooting the subject from up, down, left, right, or behind. Here, the external image data is C
Refers to data captured by CD1. However, also in this case, the reproduction display of the image data photographed by the CCD 1 can display only the photographed fixed reproduction image as in the case of the fixed type VTR.

[0015] In the "camera-integrated video tape recorder" described in Japanese Patent Application Laid-Open No. 5-244566, an enlarged display of a reproduced image can be realized when reproducing image data recorded using the attached CCD1. But,
The enlarged image has a disadvantage that the display quality of the image is lower than that of a normal reproduction display screen. In addition, by setting the magnification of the enlarged image to a constant value and recording, during reproduction and display, it is possible to select and display either the normal image or the above enlarged image. Although an image can be displayed, in this case, only an enlarged screen with a fixed magnification can be displayed, and a problem remains that an arbitrary enlarged magnification screen cannot be displayed.
Further, there is no function of displaying a non-displayed portion by reducing the size of the playback display image or moving (slide) / rotating the playback display image. Further, it is not possible to compose an original image by displaying an undisplayed portion by enlarging / reducing, moving (sliding) / rotating the reproduced image. In particular, the functions described above can be easily realized with the development of an image recording medium such as a DVD capable of recording a large amount of image data and a CPU capable of processing a large amount of data at a high speed one after another. Was.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIG. As shown in the conventional example, there are roughly the following three methods of capturing image data from outside. The first is obtained from an attached camera (CCD1), the second is obtained from a broadcasting station via radio waves, and the third is obtained from an already recorded image recording medium. Upon reception from the camera, image data is received from the attached CCD1. In the figure, 16 is an image data recording condition setting unit, and 17 is an image data recording control unit. When an image signal is received from outside such as a broadcasting station, the analog image signal data 10 is received by the image signal data receiving unit 11. This is mainly fixed type V
The image signal data receiving unit 1 is used for a TR.
Reference numeral 1 denotes an antenna of a television or the like, and image data received from the antenna is mainly image data of a television program. The received image data is subjected to signal processing in an analog signal processing unit 2, converted into a digital signal in an A / D conversion unit 3, processed in a digital signal processing unit 4, and processed in an image recording unit. 5 is stored. Generally, a magnetic tape or DV set in the image data recording unit 5 is used.
D or other image recording medium. Such an image recording medium is detachable from the image recording unit 5, and has an advantage that once recorded (recorded) image data can be reproduced by a VTR of the same standard. In particular, D
An image recording medium such as a VD has a large capacity in spite of its light weight compared to a conventional image recording medium, and is preferable as the image recording medium used in the present invention.

Next, a method of reproducing the image data recorded on the image recording medium as described above will be described. The image data in the image recording medium is reproduced by the image reproducing unit 6. At this time, settings such as image enlargement / reduction or movement (slide) / rotation for the screen to be reproduced are performed by the image enlargement / reduction / movement / rotation setting unit 12. The information set by the image enlargement / reduction / movement / rotation setting unit 12 is used for image enlargement / reduction.
An instruction is given to the image reproduction unit 6 via the reduction / movement / rotation control unit 13. The image reproducing unit 6 reproduces an image based on information from the image enlargement / reduction / movement / rotation control unit 13 and image data in the image recording medium.

Next, the features of the present invention will be described in comparison with a conventional VTR. First, the first feature is the CCD1 of the camera.
The image data received and recorded from the VTR is more detailed and has a larger capacity than the recorded image data recorded by the conventional VTR. Various settings are made to the image data recording condition setting unit 16 during image data recording. FIG. 2 shows a condition setting flow of the image data recording condition setting unit 16.

In the condition setting flow shown in FIG. 2, it is determined in step S20 whether or not an enlarged display is to be performed during image reproduction. If the enlarged display is to be performed, the magnification of the recorded image is set in step S21. Next, in step S22, it is determined whether or not to perform reduced display or movement (slide) display at the time of image reproduction. If reduced display or movement (slide) display is to be performed, recording outside the shooting range is set in step S23. Then, in step S24, steps S21 and S23 described above are performed.
The setting value set in the step is set by instructing the image data recording control unit 17 from the image data recording condition setting unit 16 of the camera.

In this case, as a setting item, step S21
The "recording image magnification" set in step S23 and the "out-of-shooting range recording" set in step S23. The setting of “recorded image magnification” is an item for setting how detailed image data (that is, a large number of pixels per unit area) is stored for image data by a normal VTR during image recording. It is. For example, if the magnification is set to 2.0 times, the image data is stored in an amount of 2 × 4 × 2 times the normal image data. In FIG. 3, one cell is represented as one pixel constituting the image data. However, as shown in FIG. 3A, normal image data is composed of 16 pixels per one display area. On the other hand, in the case of the embodiment of the present invention in which the above item is set to 2.0 times, the image data is composed of 64 pixels as shown in FIG.

"Recording outside the photographing range" in step S23
Is an item for setting up to what level image data outside the range of an image that can be confirmed on the captured image display monitor of the VTR is stored. In other words, in the conventional VTR, the photographing screen checked by the photographer on the photographed image display monitor and the range of the actually recorded image data match, whereas in the present invention, the range is set in step S23.
The setting of "recording outside the photographing range" enables a larger amount of image data to be recorded than the photographing screen confirmed in the normal recording area of the photographed image display monitor.

FIGS. 4A, 4B and 4C show a conventional VT.
In the case of R, FIGS. 5 (a), 5 (b) and 5 (c) show the comparison of the shooting, recording and reproduction ranges in the case of the present invention. In this example, the setting of “recording outside the photographing range” is multiplied by 1.5. As apparent from a comparison between FIG. 4 of the conventional example and FIG. 5 of the present invention, FIG.
FIG. 5A shows the same photographing target image range shown in FIG.
The range of the image data recorded on the image recording medium in the case of the present invention shown in FIG. 4B is 1.5 times longer and wider than that of the conventional example shown in FIG. And
The reproduced image in the normal state is the same as shown in FIG. 4C and FIG. 5C. This is because the image data recording condition setting unit 16
Are set to the image data recording control unit 17, and the control is performed by controlling the photographing range of the CCD 1 to 1.5 times. At this time, the extended shooting range is reflected in the image data amount, but does not change with respect to the field of view of the photographer.

Next, a reproduction function for the recorded image data will be described. In the present invention, at the time of image reproduction, the image enlargement / reduction / movement / rotation setting unit 12 shown in FIG.
, Necessary conditions are set at the time of image reproduction, and an instruction is issued to the image enlargement / reduction / movement / rotation control unit 13. Upon receiving the instruction, the image enlargement / reduction / movement / rotation control unit 13 issues an instruction for the reproduced image to the image reproduction unit 6. The image reproducing unit 6 retrieves necessary image data from the image recording medium in the image recording unit 5 according to the instruction and performs reproduction display.

FIG. 6 shows the image enlargement / reduction / movement / movement shown in FIG.
FIG. 5 is a diagram showing a condition setting flow at the time of reproduction in a rotation setting unit 12. In FIG. 6, first, it is determined in step S30 whether or not to perform the enlargement / reduction processing on the reproduced image. When the enlargement / reduction processing is to be performed, in step S31, the enlargement portion is designated and the enlargement or reduction ratio is designated. Next, in step S32, it is determined whether or not to perform a moving or sliding process on the reproduced image. If this process is to be performed, a moving direction and a moving amount are specified in step S33. Next, in step S34, it is determined whether or not to perform a rotation process on the reproduced image. When this process is performed, a rotation direction and a rotation angle with respect to the X, Y, and Z axes are specified. Then, in step S36, steps S31, S33, S
The designated condition set in 35 is instructed to the image enlargement / reduction / movement / rotation control unit 13.

In this case, the designated items include the three items of enlargement / reduction, movement (slide), and rotation as described above. First, designation of “enlarge / reduce” will be described. This setting specifies how much magnification /
This is for determining whether to perform the reduced display. There are "Enlarged part" specification and "Enlargement (reduction) magnification" specification as parameters. To perform enlarged display, specify "Enlarged part" and "Specify enlargement magnification". Performs "designation of reduction ratio". Also, the upper limit value of the enlarged display and the lower limit value of the reduced display are set at the recording image magnification setting and the setting items of the image data recording condition setting unit 16 of the camera, which are set in steps S21 and S23 in FIG. It is determined by the recording setting outside the shooting range. For example, if the recording image magnification is set to 2.0 times, the upper limit of the enlargement magnification is 2.0, and if the recording outside the shooting range is set to 2.0, the lower limit of the reduction magnification is 0.5.
Becomes

Next, movement (slide) designation will be described. This is specified when the reproduced image is moved (slid) left and right or up and down so that an image of an undisplayed portion before the slide can be displayed. As a parameter to specify
Although there are "moving direction" and "moving amount", the designation of "moving direction" is a parameter for determining whether to move (slide) in the left, right, up or down direction of the image display screen.
Is a parameter that determines how much to move in the determined direction. For example, when the right side is selected as the moving direction, the reproduction screen moves to the right as a whole (the display center position moves to the right). The image shown in FIG. 5C moves to the right as shown in FIG. 7, and as a result, the image on the right side of the screen that was not displayed during normal playback is displayed, and the image on the left side displayed on the contrary is displayed. The image disappears.

Next, the rotation designation will be described. this is,
This is used to rotate a normal reproduced image and display the rotated image. There are "rotation axis" and "rotation angle" as parameters to be specified. "Rotation axis" means X axis, Y axis
The X axis is a horizontal axis with respect to the image display screen, the Y axis is a vertical axis, and the Z axis is a vertical axis as shown in FIG. However, since image data obtained from a CCD 1 (camera) such as a handy-type camera-integrated VTR does not include a rotated image in the X and Z directions, this function is effective only when an external radio wave is transmitted. This is the case of the received data received, and only when this radio wave contains rotated image data in the X and Z axis directions.

As described above, in the present invention, various editing (enlargement /
Although there is a function of (reduction / movement / rotation), there is also provided a function of registering these editing results and displaying the edited image as a standard display during subsequent reproduction. The setting in this case is shown in FIG.
Is performed by the knitting image registration setting unit 14, and is instructed by the knitting image registration control unit 15. The knitting image registration control unit 15 that has received the instruction performs control for recording the knitted display image displayed on the image display unit 9 on the image recording medium in the image recording unit 5 as image data based on the set conditions. I do.

FIG. 9 is a diagram showing a registration setting flow in the knitting image registration setting section 14. In FIG. 9, first, it is determined whether or not to register a knitted image in step S40. When the knitting image is not registered, the flow ends in step S44. When the knitting image is registered, the registration condition of the speed and brightness at the time of reproduction is set in step S41. Next, step S42
It is determined whether or not to delete image data other than the registration target image data. To delete the image data, an instruction to delete the image data not to be registered is issued in step S45, and step S4 is performed.
In step 3, the knitted image registration control unit 15 is instructed to delete the image data not to be registered, together with the speed and brightness at the time of reproduction from step S41. If it is determined in step S42 that the image data other than the image data to be registered is not deleted, the registration conditions of the speed and brightness at the time of reproduction set in step S41 are instructed to the knitting image registration control unit 15 in step S43.

As described above, the setting of the “registration condition”
There are "playback speed" and "playback brightness", which are the normal speed when playing the knitted image, or what percentage of the normal time.
The speed is specified, and the normal brightness at the time of reproduction or the percentage of the light amount at the normal time is specified. The setting of "deletion of non-registered image data" is for setting whether to delete unnecessary image data relating to image data edited and registered. That is, when the image is edited to be enlarged, only the image data necessary for the enlarged display is recorded, and other unnecessary image data, for example, image data necessary for reduction, movement (slide) / rotation processing are deleted. Is done. As a result, the capacity of image data recorded on the image recording medium is reduced, and other image data can be recorded accordingly. However, at the same time, editing work such as enlargement / reduction, movement (slide) / rotation, and the like as described above becomes impossible. If it is desired to perform the same editing work on an image in the future, the above parameter may be invalidated.

Next, the difference between the conventional VTR and the image data processing in the image reproducing section 6 in the present invention will be described.
Processing of image data in a conventional VTR is usually performed by a simple one-to-one correspondence in which one pixel of acquired image data is projected onto one pixel of a reproduced image display screen. On the other hand, according to the present invention, when the image is recorded at an enlargement magnification of 2.0, four times the pixels of the image data required for normal reproduction are recorded. When the image is projected on one pixel of the screen for use, the entire image does not fit within the screen. Therefore, at the time of image reproduction, a process of combining a plurality of image data into one becomes necessary.

FIG. 10 shows the processing in the image reproducing unit 6 of the image data (a) recorded by the conventional VTR and the image reproducing unit 6 of the image data (b) recorded at a magnification of 2.0 in the present invention. Is a comparison of the state of the processing in FIG. According to the present invention, image data composed of a plurality of pixels is
Normal reproduction is realized by projecting one pixel of the reproduction display screen (c) through a process of converting the image data into image data for pixels. In this case, when the enlargement magnification of the image data is two times, it is necessary to combine the image data of four pixels into one, and when the enlargement magnification is three times, the image data of nine pixels is reduced to one.
They need to be put together.

Such use of image data more than in the conventional example becomes effective only when the function of enlarging and displaying a part of the reproduction display screen is used. In other words, when it is desired to display a part of the reproduction display screen at 2.0 times the normal size and display it, the four pixels of image data that have been combined as described above are directly converted into one pixel of the reproduction display screen. What is necessary is just to project. At this time, in addition to the image reproducing unit 6, an image enlargement / reduction / movement / rotation control unit 13 and an image enlargement / reduction / movement / rotation setting unit 12 are added to perform processing. The image enlargement / reduction / movement / rotation control unit 13 controls the image playback unit 6 based on information such as the enlargement portion and the enlargement magnification from the image enlargement / reduction / movement / rotation setting unit 12, and the image playback unit Reference numeral 6 controls acquisition of necessary image data from the image recording medium in the image recording unit 5 and display of the image data.

Referring to FIGS. 4 and 5, a description will be given of a further application example of the present invention in which image data is stored in a wider range than a conventional VTR reproduction image range. Conventional VT
At R, the image captured by the CCD 1, the image data recorded with the image, and the image reproduced based on the image data have the same range as shown in FIG. Therefore, the captured images are the sun, mountains, lakes, and trees as shown in FIG. 4, which are displayed at the time of reproduction. No people are displayed. Since these animals and people do not exist in the image data itself,
These cannot be displayed even during subsequent reproduction.

On the other hand, according to the present invention, in addition to the sun, mountains, lakes and trees shown in FIG.
Only mountains, lakes and trees. That is, image data in a wider range than the shooting range for normal display is recorded. The image data recording condition setting unit 16 and the image data recording control unit 17 described above determine how much image data in a wider range than the shooting range for normal display is recorded. As shown in FIG.
First, one of the setting items in the image data recording condition setting unit 16 is set.
One of the settings is “record outside the shooting range”. FIG. 5 (b)
Is a photographing range that can be confirmed by the photographer, and a dotted line is image data outside the range. In the embodiment shown in FIG. 5B, the set magnification of “recording outside the photographing range” is 1.5 times.

When the setting is made to record an image outside the normal range, the image data recording control unit 17
The magnification information (1.5 times in this case) is transmitted to CD1. The CCD 1 that has acquired the magnification information expands the field of view based on the magnification information, and at the same time, increases the amount of image data transferred to the analog signal processing unit 2. However, the part where this field of view was widened is unknown to the photographer. Then, when normal reproduction is performed based on the image data recorded as described above, the image reproduction unit 6 automatically recognizes a solid line portion in FIG. 5B, which is a normal photographing range, and displays it in FIG. 5C. Display on screen as shown.

An image outside the photographing range photographed in this way is, for example, a photographed image (sun, mountain, lake and tree) at the time of normal reproduction, and even if it is not conscious at the time of photographing, something unsatisfactory at the time of reproduction. Can be used to search for a suitable subject around when the user feels. Further, it can also be used when the user notices that an important image is located at the edge of the screen during reproduction and wants to move it to the center of the screen. For example, FIG. 7 shows an image obtained by moving (sliding) the reproduced image of FIG. 5 to the right side. Here, “animal” which is not displayed in the conventional reproduction is displayed. Furthermore, when a specific image is enlarged / reduced or rotated, the operation can be performed based on the operation method described above, and various knitting processes can be performed on a reproduced image that cannot be realized by the conventional function.

[0050]

According to the present invention having the above-described configuration, it is possible to perform enlargement / reduction display on a reproduced image when reproducing image data from the outside, and to display (not slide) the displayed image by moving (sliding) / rotating the image. Can be displayed, so that not only the fixed reproduction display of the conventional image data but also the reproduction and editing according to the user's preference become possible. In addition, even when the enlargement / reduction function is used, it is possible to display a high-quality and wide-range reproduced image at any magnification from the upper limit of the magnification set at the time of shooting to the lower limit of the reduction. Become.
Further, when image data for enlargement / reduction, movement (slide) / rotation is transmitted to received image data of a television broadcast or the like in addition to conventional image data, a wider range of reproduced image data can be used.
