Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image file device for recording or reproducing a unit still image obtained by dividing a large-screen still image into frame units.

[0002]

2. Description of the Related Art As a method of reproducing a large-screen still image of a size larger than the display size of the screen from a recording medium, the large-screen still image is divided into frames in advance, and the divided still images of the frame units are divided into large-screen images. There is a method in which a still image is recorded on a recording medium such as an optical disk as a part of the still image and the still image is reproduced from the recording medium.

As a conventional technique using such a method, for example, there is one described in Japanese Patent Laid-Open No. 12424/1990. In the conventional example disclosed in Japanese Patent Laid-Open No. 12424/1990, the file name, the arrangement coordinates on the large screen of the unit still image obtained by dividing the large screen still image, and the storage position of the unit still image are the unit still image. There is disclosed a technique in which division management information associated with each other by the number of items and unit still image groups specified at each storage position in the division management information are recorded on an optical disc.

[0004]

However, in this technique, when the unit still image recorded on the optical disc is to be accessed independently by designating a serial number unique to the optical disc, the unit still image designated by the serial number is used. It is impossible to determine which part of the large-screen still image corresponds to. Therefore, even if the designated unit still image is viewed on the monitor and the designated unit still image is displayed on the monitor by, for example, the arrow key of the keyboard, the neighboring unit still image cannot be specified. There is such a problem.

Actually, in this conventional example, unit still images are divided and recorded on a plurality of optical discs of the above-mentioned format, and each optical disc is simultaneously driven based on division management information to reproduce a plurality of unit still images at a time. By doing so, the purpose is to increase the speed, and no consideration is given to designating and reproducing individual still images. The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an image file device that can easily specify individual unit still images belonging to a large-screen still image.

[0006]

An image filing apparatus according to the present invention records an arbitrary still image in a group of still images in a mutual relation composed of a plurality of still images in a unit of a frame in a recording medium. In the image filing apparatus, there are two types of recording position information of all still images belonging to the mutual still image group and relative position information of the still images belonging to the mutual still image group in the mutual still image group. Join information including information is formed for each still image belonging to the interrelated still image group, and joint information formed for each still image belonging to the interrelated still image group is added to each still image belonging to the interrelated still image group. It is characterized in that it is recorded on a recording medium in association with an image.

Further, the image filing apparatus of the present invention records a group of mutually related still images composed of a plurality of frame-wise still images which are related to each other, and further belongs to the group of mutually related still images. The joining information including two types of information, that is, the recording position information of the still image and the relative position information of the still image belonging to the interrelated still image group in the interrelated still image group is added to the interrelated still image group. An image file device for reproducing an arbitrary still image belonging to the interrelated still image group from a recording medium recorded in association with each still image to which the still image belongs, of the still images belonging to the interrelated still image group. If a specified operation is performed to display any still image belonging to the mutual still image group while a specific still image is being displayed, it corresponds to the still image being displayed. Based on the relative position information in the joining information, the recording position information of the specified still image is specified from the recording position information of all the still images belonging to the mutual related still image group in the joining information, and the specified recording is performed. It is characterized in that reproduction control of a still image is performed based on position information.

[0008]

The present invention combines the recording position information of all the still images belonging to the mutual related still image group and the relative position information of the still images belonging to the mutual related still image group in the mutual related still image group. Information is formed for each still image belonging to the mutual still image group, and the joining information formed for each still image belonging to the mutual still image group is associated with each still image belonging to the mutual still image group. And record it on the recording medium.

Further, according to the present invention, an arbitrary still image belonging to the interrelated still image group is displayed while a specific still image among the still images belonging to the interrelated still image group is displayed. When there is a designation operation, based on the relative position information in the joining information corresponding to the still image being displayed, the recording position information of the designated still image is added to all of the interrelated still image groups in the joining information. It is specified from the recording position information of the still image, and the still image is reproduced and controlled based on the specified recording information position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the image filing device of the present invention will be described below with reference to FIGS. FIG. 1 is a diagram showing a relationship between a large-screen still image and a unit still image. The large-screen still image is an image having a size larger than the screen size of the display monitor, and is an image obtained as a set of a plurality of unit still images having the screen size. In other words, the unit still image is an individual still image belonging to the large-screen still image. For example, the unit still image is a still image obtained by dividing the large screen still image as shown in FIG. 1 into frame units, and is a still image of a part of the large screen still image. If the screen size of the display monitor is 1920 × 1035 pixels, for example, unit still images (1-1, 1-2, 1-3, 2-1, 2-2, 2
-3, 3-1, 3-2, 3-3) are each 1920 × 10.
It has 35 pixels, and a large-screen still image is 5760 x 3105.
It is a pixel.

That is, a still image group composed of a plurality of frame-by-frame still images that are mutually related is a large-screen still image, and each of the mutually-related frame-based still images is a unit still image. Although FIG. 1 shows a case where unit still images, which are pictures of a part of a large-screen still image, are collected and one picture is expressed as a large-screen still image, the present invention is not limited to this. A still image is a picture or character information completed by itself, and a still image group in which such unit still images are grouped by a certain common classification may be a large-screen still image.

FIG. 2 is a diagram showing joining information formed in a one-to-one correspondence with each unit still image. The joining information is
Recording position information of all unit still images belonging to a still image group (large-screen still image) having mutual relation, and relative position of the unit still image belonging to the still image group having mutual relation to each other in the mutual still image group. Information, including information,
One-to-one for each unit still image belonging to a large-screen still image
Exists in correspondence with.

In FIG. 2, the joining information is the horizontal number H,
Vertical number V, relative position information Z, recording position information I _{11 to} I _MN
Composed of. The horizontal direction number H indicates the number of unit still images belonging to the large-screen still image in the horizontal direction, and the vertical number V indicates the number of unit still images belonging to the large-screen still image in the vertical direction. The recording position information I is information for specifying all unit still images belonging to the large-screen still image, and is, for example, an image designation number of the unit still image. The image designation number is a serial number of an image unique to the recording medium, and a different number is assigned to each unit still image recorded on the recording medium.
The order in which the image designation number is recorded as the recording position information is the order of the coordinates indicating the arrangement position of the unit still image in the large-screen still image. For example, the coordinate order is coordinate (X,
In (Y), if (1, 1) is the initial value, Y is increased by one and Y is maximized. Then, X is increased by 1 and Y is reset to the initial value, and Y is sequentially increased. In the example of FIG. 1, the coordinates (1,1), (1,2),
(1,3), (2,1), (2,2), (2,3),
The order is (3, 1), (3, 2), (3, 3). The image designation number is recorded in the recording position information in this order.

In the large-screen still image in FIG. 1, 1
-1, 1-2, 1-3, 2-1, 2-2, 2-3, 3-
Assuming that the image designation numbers of the unit still images of 1, 3-2 and 3-3 are 0, 1, 2, 3, 4, 5, 6, 7 and 8 in order, the recording position information I ₁₁ , I ₁₂ , I. ₁₃ , I ₂₁ , I ₂₂ ,
I ₂₃ , I ₃₁ , I _32, and I ₃₃ are 0, 1, 2,
3, 4, 5, 6, 7 and 8. This recording position information I
Is information unique to the large-screen still image, and is common to all unit still images belonging to the large-screen still image.

The relative position information Z is information for knowing what position the unit still image corresponds to in the large-screen still image. For example, the relative position information Z indicates the number of recording position information in the recording position information. It is the number shown. For example, assuming that the unit still image 2-2 in FIG. 1 is the unit still image of itself, the unit still image 2-2 is 5 in the recording position information.
Therefore, the relative position information Z is 5. The relative position information Z is information unique to each unit still image belonging to the large-screen still image, and if the unit still image is different, the relative position information Z is also different.

FIG. 3 is a diagram showing a recording format of a unit still image and joining information on a recording medium. The unit still image and the joining information described above are recorded on a large-capacity recording medium such as an optical disc. The recording medium has an image data section for recording a unit still image, and the image data section is divided into a plurality of image data areas. One unit still image and its header information are stored in one image data area. Each image data area is numbered in the order of addresses, and the number corresponds to the image designation number of the unit still image. Further, the recording medium has an additional data section for recording the joining information, like the unit still image, and the additional data section is divided into a plurality of additional data areas. Join information and its header information are recorded in one additional data area. The additional data area has a one-to-one correspondence with the image data area, and the additional data area N
The unit still image of (N is an integer of 0 or more) corresponds to the joining information of the additional data area N.

In the recording medium, the image data directory portion in which the start address of each image data area is recorded in the number order of the image data area and the start address of each additional data area are recorded in the number order of the additional data area. There is an additional data directory section, and disc identification information for identifying the recording medium, creation date, various flag information, the start address of the image data directory section, the start address of the additional data directory section, etc. are recorded. There is a volume part. Volume part is, for example, 1024
A fixed size length of bytes is recorded from the beginning of the recording medium, and a directory part and a data part are recorded with a variable size length. Thus, in the recording medium, the volume part, the directory part, and the data part are recorded in a three-layer structure.

Therefore, in order to obtain the target unit still image by designating the image designation number of the unit still image, the head address of the image data directory portion recorded at the fixed position of the volume portion is acquired and the image data directory is obtained. The head address of the image data area recorded in the area is acquired by referring to the entry that matches the image designation number in the set, and the unit still image in the image data area is accessed.

Further, in order to obtain the joining information corresponding to the target unit still image for which the image designation number is designated, similarly, the leading address of the additional data directory portion recorded at the fixed position of the volume portion is acquired. , The start address of the additional data area in which the target joining information is recorded is acquired by referring to the entry in the additional data directory part having the same number as the image designation number of the unit still image, and the joining information in the additional data area is acquired. To access.

Incidentally, the values of the recording position information and the relative position information in the joining information are not necessarily limited to those in the above-mentioned example.
The recording position information may directly indicate the recording address of the unit still image instead of the image designation number. In that case, the recording address of the unit still image is not specified by referring to the image data directory section described above. If the unit still image belongs to the large-screen still image, the recording address can be directly specified. Also, the relative position information may be, for example, a coordinate value instead of the number in the recording position information.

FIG. 4 is a diagram showing a functional block diagram of the image filing apparatus. The operation of one embodiment of the device of the present invention will be described below using functional blocks. The contents include recording of a unit still image belonging to a large-screen still image read by the image scanner 8 and its joining information on the recording medium 1,

First, 1-1, 1-2, 1-3, 2 of FIG.
The unit still images of -1, 2-2, 2-3, 3-1, 3-2 and 3-3 are designated by image designation numbers 0, 1, 2, 3,
It will be described how to record 4, 5, 6, 7 and 8 on the recording medium and also record the joining information on the recording medium. With the original image of the unit still image 1-1 in FIG. 1 placed on the original table of the image scanner 8, the control unit 9 causes the instruction unit 7 to set the image designation number to 0.
If there is an instruction to read the original image and a recording instruction,
The image scanner 8 is instructed to start reading the original image of the unit still image and the frame memory (for example, M1) to be the storage destination is designated. Further, the output from the image scanner 8 can be stored in the frame memory M1 of the storage means 3. Therefore, the original image of the unit still image 1-1 in FIG. 1 is read by the image scanner 8 and the unit still image is stored in the frame memory M1.

The control means 9 controls the 1-1 unit still image (image

Create the joining information as shown in Fig.
The information is stored in the combined information storage means 10.

The control means 9 firstly writes to the write control means 11 1-stored in the frame memory M1.
A request is made to record the unit still image 1 (image designation number 0) in the image data area 0 (see FIG. 3) of the recording medium 1. Then, the writing control means 11 specifies the address of the image data area 0 of the recording medium 1 to the drive 2, and accordingly, the unit still image of the frame memory M1 is recorded in the image data area 0 of the recording medium 1.

Further, the control means 9 is the write control means 1
1 stored in the joining information storage means 10
Request to record the joining information of the unit still image of -1 in the additional data area 0 (see FIG. 3) of the recording medium 1. Then, the writing control means 11 specifies the address of the additional data area 0 of the recording medium 1 to the drive 2, and accordingly, the joining information of the joining information storage means 10 is recorded in the additional data area 0 of the recording medium 1. . As a result, the unit still image 1-1 (image designation number 0) is recorded in the image data area 0 of the recording medium 1, and the corresponding joining information is recorded in the additional data area 0 of the recording medium 1.

After that, the control means 9 creates the image data directory section, the additional data directory section and the volume section of the recording medium 1, and the write control section 11 creates the image data directory section, the additional data directory section and the volume section. When writing is requested, the writing control means 11 specifies an address to record these on the recording medium 1 and records them on the recording medium 1.

The control means 9 controls the above operations 1-2, 1-
3, 2-1, 2-2, 2-3, 3-1, 3-2 and 3-
Repeatedly for 3 unit still images, 1
-1, 1-2, 1-3, 2-1, 2-2, 2-3, 3-
The unit still images 1, 3-2 and 3-3 (image designation numbers 0, 1, 2, 3, 4, 5, 6, 7 and 8) are image data areas 0, 1, 2 of the recording medium 1, respectively. 3,
4, 5, 6, 7, and 8 are recorded in the additional data areas 0, 1, 2, 3, 4, 5, 6, 7, and 8 of the recording medium 1 and the joining information corresponding to each unit still image is recorded. Will be recorded.

Next, while the unit still image and the joining information as described above are recorded on the recording medium 1, the unit still image recorded on the recording medium 1 is reproduced by designating the image designation number, A description will be given of how a unit still image adjacent to the unit still image being reproduced is reproduced using the arrow keys on the keyboard of the instruction means 7. For example, the image designation number 4 is designated by the designation means 7, and the corresponding unit still image (2-2)
When it is instructed to reproduce, the control means 9 requests the read address generation means 12 to read the volume portion, and obtains the volume portion from the recording medium 1. Further, the control unit 9 obtains the read addresses of the image data directory unit and the additional data directory unit from the volume unit, and requests the read control unit 12 to read the image data directory unit and the additional data directory unit. Thereby, the control means 9 obtains the image data directory portion and the additional data area directory portion, and adds the image data area 4 for recording the unit still image (2-2) of the image designation number 4 and the corresponding joining information. The data area 4 becomes accessible.

When the read control means 12 functions to read the unit still image of the image data area 4 and the joint information of the additional data area 4, the unit still images of the recording media 1 to 2-2 and the corresponding joint information are reproduced. Then, the unit still image 2-2 is stored in the storage means 3, for example, the frame memory M1.
And the joining information is stored in the joining information storage means 10. Then, the control means 9 controls the switching means 4 to display the unit still image of the frame memory M1, and the monitor 6 displays the unit still image of 2-2.

While the 2-2 unit still image is being displayed on the monitor 6 in this manner, the operator operates the arrow keys of the instruction means 7, for example, the up key to display the unit still image. Reproducing 1-2 unit still images of unit still images (1-2, 2-1, 2-3, 3-2 unit still images in FIG. 1) adjacent to the unit still image (2-2) When the instruction to do so is given, the control means 9 causes the joining information storage means 1 to
The joining information stored in 0 is referred to. This joining information includes horizontal direction number H of 3, vertical direction number of 3 and relative position information Z.
5, recording position information I ₁₁ , I ₁₂ , I ₁₃ , I ₂₁ , I ₂₂ , I
₂₃ , I ₃₁ , I _32, and I ₃₃ are 0, 1, 2, 3,
4, 5, 6, 7 and 8.

Based on the horizontal direction number H and the vertical direction number V, the control means 9 causes the unit still image (2-
The large-screen still image to which 2) belongs is a large-screen still image formed by three unit still images in the horizontal direction and three unit still images in the vertical direction, and the recording position information is arranged in a matrix order of 3 rows and 3 columns. You can recognize that. At this time, the control means 9
The recording position information is managed by associating each of the recording position information arranged in a matrix of rows and three columns with a matrix format (coordinate format). That is, the values 0, 1, 2, 3, 4, 5, of the recording position information,
6, 7, and 8 have coordinates (1, 1), (1, 2), (1,
3), (2,1), (2,2), (2,3), (3,
1), (3, 2) and (3, 3) are managed. Further, the control unit 9 refers to the recording position information, and since the value is Z = 5, the control unit 9 knows that the fifth value 4 of the recording position information is the image designation number of its own unit still image, and It can be seen that the unit still image of is the unit still image located at the coordinate (2, 2) in the large-screen still image.

By calculating coordinates based on this,
The control unit 9 specifies the recording position information of the unit still image positioned above the currently displayed unit still image of the unit instructed by the instruction unit 7. Since the unit still image of itself is the unit still image located at the coordinates (2, 2), the unit still image located on the unit still image has the Y coordinate equal to its Y coordinate and the X coordinate of its own X image. It can be seen that the unit still image is located at a coordinate that is one smaller than the coordinate, that is, the coordinate (1, 2). Since the control means 9 manages the coordinates and the recording position information in association with each other, the coordinates (1, 2) immediately follow.
It can be seen that the recording position information corresponding to 1 has the value 1.

In this way, the control means 9 controls the joining
Based on the relative position information (Z = 5) of the information,
All unit stills belonging to the large-screen still image in the joining information
Image recording position information (I₁₁, I₁₂, I₁₃, I_{twenty one}, I_{twenty two},
I_{twenty three}, I₃₁, I₃₂And I₃₃) From the instruction means 7
The recording position information (I ₁₂
= 1) is obtained.

Since the recording position information (I ₁₂ = 1) is the image designation number as it is, the control means 9 can determine that the target unit still image has the image designation number 1, and refers to the image data directory section. Then, the start address of the image data area 1 stored in the entry 1 is acquired, and the start address of the additional data area 1 stored in the entry 1 is acquired by referring to the additional data directory section. The control means 9 is different from the read control means 12 in
Unit still image recorded in image data area 1 1-
2 and reproduction of the joining information corresponding to the unit still image 1-2 recorded in the additional data area 1 is requested. Then, the unit still image 1-2 and the corresponding joining information are reproduced from the recording medium 1, the joining information is stored in the joining information storage unit 10, and the unit still image 1-2 is stored in the frame memory M2. The unit still image 1-2 is the frame memory M2
Stored in the unit still image (2--) of the frame memory M1 according to the number of times the operator has pressed the up key.
2) to the unit still image of the frame memory M2 (1-2)
In addition, the image displayed on the monitor 6 moves with a predetermined amount of scroll effect. Therefore, one still image in which a part of the unit still image 2-2 and a part of the unit still image 1-2 are connected is displayed on the monitor 6, and the portion of the large-screen still image desired by the operator is displayed. Can be displayed.

If there is no unit still image adjacent in the direction designated by the operator among the unit still images adjacent to the currently displayed unit still image, there is no such unit still image. Information is notified and movement of the display image by reproducing or scrolling the unit still image is prohibited. Based on the relative position information of the joining information stored in the joining information storage means 10, guide information indicating the presence of all unit still images adjacent to the unit still image of itself, for example, arrow information is displayed on the monitor 6. By doing so, the presence of a unit still image adjacent to the currently displayed unit still image may be clearly shown to the operator, and guidance of the designated operation may be provided.

In the above-described embodiment, the case where only a unit still image group belonging to one large screen still image is recorded has been described, but the present invention is not limited to this, and a unit still image group belonging to another large screen still image is recorded. Needless to say, both may be recorded together. At this time, naturally, the image designation numbers of the respective unit still image groups belonging to different large-screen still images are individually different.

Further, in the above-mentioned embodiment, since the instructing means 7 designated by the operator is the arrow key of the keyboard, only the unit still images adjacent to the top, bottom, left and right of the unit still image being displayed can be designated. , For example, by combining the arrow keys on the keyboard with the number keys from 0 to 9,
An arbitrary unit still image may be designated. For example, from the currently displayed unit still image to the right (arrow key)
When a unit still image separated by two (numerical key) is directly designated, the recording position information of the directly designated unit still image is obtained based on the relative position information of the unit, and the directly designated unit is obtained. Play a still image.

It is needless to say that the functional blocks of the above-described embodiments may be configured by software or hardware as necessary, and the present invention includes some aspect. . Furthermore, the above-described embodiments are merely examples of the present invention, and various modifications can be made if necessary, and the present invention described in the claims includes all such modifications.

[0043]

According to the present invention, the recording position information of all unit still images belonging to a large-screen still image and the relative position of the unit still image belonging to the large-screen still image within the large-screen still image are recorded on the recording medium. Since the joining information including the position information is recorded corresponding to each unit still image, even if the unit still image recorded on the recording medium is individually accessed by designating the image designation number or the like, It is possible to determine which part of the large-screen still image the unit still image designated by the image designation number corresponds to. Therefore, even if the designated unit still image is displayed on the monitor and a designation operation is performed to display an arbitrary unit still image belonging to a large-screen still image on the monitor, the target unit still image can be specified and the unit still image can be specified. The image can be reproduced from the recording medium.

Further, since the recording position information of the joining information is recorded in the order of coordinates, only the recording position information needs to be recorded, and it is not necessary to additionally record the coordinate information.
