[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image filing apparatus which effectively stores recorded information, performs a high-quality presentation, and presents information based on the information.

[0002]

2. Description of the Related Art In recent years, an electronic still camera that converts a subject image into an electric signal by a photoelectric conversion element such as a CCD (Charge Coupled Device), performs predetermined digital signal processing, and records the digital signal on a recording medium such as a memory card has become popular. are doing. An electronic still camera employs a small and lightweight memory card as a recording medium. However, memory cards generally have a small storage capacity and are expensive. Therefore, when storing a large amount of captured image data for a long period of time, the data is transferred and stored in another large-capacity and low-cost recording medium such as an optical disk. Such an image file device is positioned in a general household as equivalent to a photo album in which silver halide photographs are pasted and stored.

FIG. 33 is an explanatory diagram showing a photo album 1. The photo album 1 is formed by binding a plurality of mounts (pages) 2, and a plurality of photographs 3 are attached to respective mounts 2 at appropriate positions. These photographs 3 are not only arranged in the order of imaging (hereinafter, referred to as temporal arrangement), but may also be arranged based on the classification according to the contents according to various intentions of the creator. May be given an arrangement according to the order and arrangement (hereinafter, these will be referred to as “directive arrangement”). In addition, the creator is Mount 2
The visual effect of the entire mount 2 is also taken into account by appropriately setting the above-mentioned attachment position. In general, the photo album 1 produced in this way is sequentially turned over the mount (page) 2 and is viewed.

FIG. 34 is a block diagram showing a conventional image file device having a function as the above-mentioned photo album. The description of the transfer sequence when data is transferred from the recording medium of the electronic still camera to the recording medium of the image file device will be omitted. FIG. 35 shows the data structure on the optical disk.

A rewritable optical disk (not shown) inserted into the optical disk device 5 is employed. As shown in FIG. 35, it is assumed that 14 pieces of still image data are recorded on the optical disc. Note that the electronic still camera compresses still image data by, for example, a JPEG compression algorithm, and compresses images (1) to (14) on an optical disc. In addition to the image data (1) to (14) of the 14 still images, management data is also recorded on the optical disk. The management data includes pointer data such as a position on the disk where each data is recorded, and reproduction of an image is controlled based on the management data. The optical disk device 5 writes data to the optical disk and reads data stored in the optical disk. Writing and reading of data to and from the optical disk device 5 is performed by SCSI (Small Computer).
System Interface) is controlled by a controller 6, and the SCSI controller 6 has a data and control bus 7.
Is supplied to the optical disk device 5 via the SCSI bus 8, and data read from the optical disk device 5 via the SCSI bus 8 is output to the MPU 9 via the data and control bus 7.

Next, the operation of reproducing a still image will be described with reference to FIGS. 36 and 37. FIG. 36 is an explanatory diagram showing a format of management data, and FIG. 37 is a flowchart showing an operation flow.

The user operates the operation keys 10 to instruct the MPU 9 to reproduce an image. The ROM 11 stores a program for controlling the MPU 9, and the MPU 9
The SCSI controller 6 is controlled via the data and control bus 7 based on the program 11 to inquire of the optical disk device 5 whether an optical disk is inserted (step S1). The result of the inquiry is given to the MPU 9 via the SCSI controller 6. When it is confirmed from the result of this inquiry that a disc has been inserted, in step S2, the MPU 9 issues a command for reproducing the management data of the frame number (1) to the SC.
Issued to the optical disk device 5 via the SI controller 6. The MPU 9 performs the following based on the reproduced management data.
Play each frame. Here, the frame corresponds to one page of the above-described photo album, and indicates one screen displayed on the image display device 16 described later. Frame (1)
Are recorded in the record numbers (n + 0) to (n + 5) of the management data as shown in FIG. Note that n of the record number indicates a system offset.

[0008] The number of objects (= 4) recorded in the record number (n + 0) indicates the number of objects to be presented to the user in one frame. In a photo album, the number of photos to be pasted on one mount Is equivalent to The number of links indicates the number of other related frames. The number of links is 2 when data of another frame is present before and after, and is 1 when data of another frame exists only on one side. In the record number (n + 1), the window position / size (x, y, h, v) of the object (1) indicating the display position and size of the object on the screen for the object (1)
And (3) compressed data pointer data indicating the recording position of the image (3) compressed data (see FIG. 35) as the object (1) and the object (1) on the optical disk. Similarly, record numbers (n + 2) to (n + 4) record data on objects (2) to (4), respectively.

FIG. 38 shows a window position and size (x,
FIG. 4 is an explanatory diagram for describing data of (y, h, v).
The display screen 17 of the image display device 16 has a frame area 18 over the entire area.
And a window region 19 for displaying each object in part. Assuming that the horizontal and vertical coordinates of the upper left end of the display screen 17 are (0, 0), the horizontal and vertical coordinates of the start end (upper left end) of the window area 19 are (x, y) as shown in FIG.
And the horizontal and vertical dimensions are given by (h, v).

In the record number (n + 6), link condition and link destination pointer data are recorded. When the link condition is satisfied, reproduction of the record number indicated by the link destination pointer is started. For example, for the frame (2), the number of links is 2 as shown in the record number (n + 6), and the record number (n + 10),
In (n + 11), the data of the frame number (1) of the link destination pointer (= record number (n + 0)) is reproduced according to the specification of the link condition “P”. Pointer (= record number (n +
12)) indicates that the data of the frame (3) is reproduced.

In step S2 of FIG. 37, the optical disk device 5 reproduces the management data of the frame (1) and supplies the reproduced data to the MPU 9 via the SCSI bus 8, the SCSI controller 6, and the data and control bus 7. M
The PU 9 stores the reproduced management data in RA as a working memory.
Store it in M12. Next, the MPU 9 reads the data of the first record number (n + 0) of the management data stored in the RAM 12.

Next, an image (3) compressed data pointer as an object (1) is read from the record number (n + 1), and an instruction command for reproducing the image (3) compressed data is issued based on the read pointer. The data is output to the optical disk device 5 via the SCSI controller 6. The optical disk device 5 reproduces the compressed image (1) data and
The controller 6 transfers the reproduction data to the RAM 12. R
The AM 12 stores the transferred image (3) compressed data at a predetermined position.

Next, the MPU 9 gives the image (3) compressed data stored in the RAM 12 to the JPEG decoder 13,
The JPEG decoder 13 decodes the compressed image (3) data and stores it at a predetermined position in the RAM 12. Next, the MPU 9 uses the management data (record number (n + 1)) on the RAM 12 to determine the window position / size (x, y,
The data of h, v) is read. The MPU 9 compares the size when the decoded image (3) data is displayed with the size of the window area, and if the display based on the image (3) data is larger, adjusts the size of the window area. The image (3) data is reduced to generate reduced image data on the RAM 12.
The display size of the decoded image data is given from the JPEG decoder 13. The MPU 9 reads the reduced image data of the image (3) from the RAM 12 and transfers it to the frame memory 14, where it is stored in a predetermined recording position of the frame memory 14 corresponding to the position of the window area.

Next, the MPU 9 has a record number (n + 2)
Of the object (2) is read and the same processing is performed. Furthermore, record numbers (n + 3), (n +
The data for the objects (3) and (4) of 4) is read out, the same processing is performed, and the data of the frame (1) is stored in the frame memory 14. The D / A converter 15 reads data from the frame memory 14, converts the data into an analog signal, and outputs the analog signal to the image display device 16. The image display device 16 places the images (3), (7), (11), and (8), which are the objects of the frame (1), on the display screen at positions defined by the data of the window positions and sizes. And the size of the displayed image P3,
Displayed as P7, P11, P8.

When one frame of the image object is displayed in step S3 in FIG. 37, the flow shifts to step S4, where the MPU 9 waits for a key input. When the user wants to view the next frame image, the user operates the operation key 10 and inputs “N”. In addition,
If the user wants to see the image in the previous frame,
If "P" is input and the operation is to be ended, "Q" is input. For example, when "Q" is input by the operation key 10, the MPU 9 ends the processing. If "P" or "N" is input in step S4, the MPU 9 shifts the processing to step S5 and determines whether or not a link condition exists.

That is, the MPU 9 reads the link condition of each frame from the management data, and performs a process by comparing with the signal from the operation key 10. Now, the image object of the frame number 1 is displayed, and the MPU 9 is reading the link condition of the record number (n + 5). here,
When "P" is input, the process returns to step S4 because the link conditions do not match, and the key input wait state is resumed. When "N" is input, the link condition is matched, and the reproduction of the data of the record number (n + 6) which is the link destination pointer is instructed. That is, in step S6, the data of the frame number (2) recorded in the record numbers (n + 6) to (n + 11) is read out and the RA
Store it in M12. Then, the process returns to step S3 to display the image object of frame (2).

FIG. 39 shows frame numbers (1) to (4) displayed when the user specifies a link condition.
It is explanatory drawing which shows the display of.

FIG. 39A shows the display of a frame (1), in which images (3), (7), (11) and (8) are displayed as objects (1) to (4). P
7, P11 and P8 are displayed. When the frame (1) is displayed, when the user inputs "N", the frame (2) shown in FIG. 39B is displayed. In frame (2), display images P9, P10, P of images (9), (10), (12) are displayed.
12 is displayed with the position and size based on the window position / size data. In the frame (3), FIG.
As shown in the figure, display images P6, P5 and P13 based on the images (6), (5) and (13) are displayed, and the frame (4) is displayed.
In FIG. 39, as shown in FIG.
Display images P1, P2 based on (2), (4), (14)
, P4 and P14 are displayed. As described above, the user inputs the key "N" to display the next frame, and the key "P" displays the previous frame.

As described above, the display screen 17 of the image display device 16
, A frame image composed of a plurality of objects is displayed, and the frame images can be sequentially switched by a simple key operation of the user, like turning up the mount of a photo album. In this way, it is possible to view an image recorded in a manner very similar to the viewing of a photo album.

By the way, as described above, the management data indicates the relationship among various data stored in a mixed manner on the optical disk. For example, in the record numbers (n + 0) to (n + 5), the image (3) compressed data belongs to the frame (1), and the frame (1) is connected to the frame (2) under the ring condition (“N”). Are described. Data relationships described in the management data are roughly divided into innate attribute relationships and acquired effect relationships. The innate attribute relationship indicates, for example, a relationship between a captured image and attribute information such as shooting condition information, related text information, and audio information obtained at the time of shooting. The shooting condition information is information such as shooting date and time, weather, zoom magnification and shutter speed, the related text information is information such as a shooting memo, and the voice information is information such as environmental sounds for several seconds before and after shooting.

The photographed image and the attribute information obtained at the time of photographing have a non-independent relationship. For example, it is meaningless to present the information of the shooting date and time alone, and it is not meaningful to present the information of the shooting date and time in relation to another image. In other words, innate attribute relationships have persistence,
The description is not rewritten. On the other hand, the relationship between data other than the innate attribute relationship is an acquired effect relationship. The acquired directing relationship can be arbitrarily described by the creator's intention.

In the electronic still camera, not only image information but also various attribute information described above can be recorded. These pieces of information can be recorded on an optical disk by the optical disk device 5. On the other hand, the creator describes each frame by describing the innate attribute relationship and the acquired effect relationship in the management data. As described above, a photographed image desired by the creator and desired attribute information are presented on the screen based on the description.

However, once the innate attribute relation and the acquired effect relation are described in the management data, there is a problem that only information based on the description is presented. Also,
There is also a problem that it is not possible to obtain a high level of effect using music and graphics data.

[0024]

As described above, in the conventional image file apparatus described above, the innate attribute relation and the acquired effect relation cannot be accurately described, so that the effective use of information and the effect of the effect can be achieved. Was not enough.

An object of the present invention is to provide an image filing apparatus capable of presenting all recordable information in a desired effect.

The MPU 21 reproduces the recorded data on the optical disk based on the program data stored in the ROM 11. When an optical disk is inserted into the optical disk device 5, the MPU 21 issues a command for reproducing the data of the volume header to the optical disk device 5 via the SCSI controller 6. In step S11 in FIG. 5, the data of the volume header reproduced from the optical disk device 6 is read out via the SCSI controller 6, and the MPU
Reference numeral 21 stores the data of the volume header in the RAM 12, which is a working memory. In step S12, the MPU
Numeral 21 reads the initial pointer from the volume header stored in the RAM 12, substitutes it for a variable PT indicating the initial pointer, and stores it in an internal register. In this embodiment, PT = 0.

Next, the MPU 21 instructs the optical disk device 5 via the SCSI controller 6 to reproduce the data recorded at the position of the pointer 0 indicated by the variable PT in step S13. The optical disk device 5 reproduces the data of SOP (1) recorded in the pointer 0, and the SCSI controller 6 transfers the reproduced data to the RAM 12 via the data and control bus 7 and stores the data. M
The PU 21 knows the number of objects to be presented (= 4) and the set number of links (= 1) from the data of the SOP (1) stored in the RAM 12.

Next, in step S14, the MPU 21 outputs the object specified by SOP (1). That is, as shown in FIG. 7, the MPU 21 reads that the AOP (1), which is the first object, is recorded in the pointer 5, and reproduces the AOP (1) recorded in the pointer 5 on the optical disk. Requests device 5.
The SCSI controller 6 receives the AO from the optical disk device 5
The reproduction data of P (1) is transferred to the RAM 12 and stored.
The MPU 21 searches the data described in AOP (1) for a file belonging to the same data type as the data type (= P) of the first object of SOP (1). As shown in FIG. 12, the data type of the first file of AOP (1) is P, and the MPU 21 requests the optical disk device 5 to reproduce the image 1 source data recorded in the pointer 19 of this file. The SCSI controller 6 transfers the reproduced data to the JPEG decoder 13. JPEG
After performing a predetermined decoding process, the decoder 13 transfers the data to the RAM 12 for storage.

On the other hand, for the first object of the SOP (1), the MPU 21 determines the position and size (W
The position and size to be displayed are specified by the data of (x, y, h, v)). If the display based on the demodulated data for the image 1 is larger than the designated display window, the MPU 21 converts the demodulated data into reduced image data by a predetermined thinning process on the RAM 12 and The data is transferred to one side and stored in the storage area corresponding to the position of the display window. Thus, preparation for presentation of the first object is completed.

Next, the MPU 21 prepares for presentation of the second object of the SOP (1). That is, M
PU 21 first receives AOP (2) recorded in pointer 6
, And an instruction to reproduce the image 2 described in AOP (2) (FIG. 13) from the pointer 10. The image 2 source data is demodulated by the JPEG decoder 13. The demodulated data is processed in the RAM 12 according to the size of the display window, and then stored in an area of the image frame memory 24 corresponding to the display window.

Next, the MPU 21 prepares for presentation of the third object of the SOP (1). The MPU 21 records the AO recorded in the pointer 15 in which the third object is described.
It requests the optical disk device 5 to reproduce P (11). AO
The reproduction data of P (11) is stored in the RAM 12. MPU
Reference numeral 21 detects, from the AOP (11), a file belonging to the same type as the data type (= G) specified by the third object of the SOP (1). As shown in FIG.
The data type of the first file of the OP (11) is G, and the MPU 21 instructs the optical disc device 5 to reproduce the graphics (1) source data recorded in the pointer 40. The SCSI controller 6 supplies the reproduction data to one of the graphics generation circuits 25. The graphics generation circuit 25 demodulates the graphics (1) source data to obtain display data. The display position of the display based on the graphics (1) source data is SOP.
It is defined by the data of W (x, y, h, v) in (1).

Next, the MPU 21 prepares for presentation of the fourth object of the SOP (1). The MPU 21 detects that the fourth object is recorded on the pointer 13, and instructs the optical disc device 5 to reproduce the AOP (9) recorded on the pointer 13. The reproduced file data is stored in the RAM 12. MPU21 is AOP (9)
To SOP (1), a file having the same data type as the data type (= M) specified by the fourth object is detected. As shown in FIG. 20, the data type of the first file of the AOP (9) is M, and the MPU 21 requests the optical disc device 5 to reproduce the MIDI (1) source data recorded in the pointer 35. SCSI controller 6
Transfers the reproduction data to the MIDI data demodulator 22 and stores it in the built-in buffer memory. Thereby, SOP
Preparation for presentation of all objects specified in (1) is completed.

Here, the MPU 21 has the image frame memory 24
And the graphics generation circuit 25 is set to the reproduction state. The image frame memory 24 outputs image data based on the source data of the images 1 and 2 to the synthesizing circuit 27, and the graphics generating circuit 25 outputs image data based on the graphics (1) source data to the synthesizing circuit 27. The synthesizing circuit 27 synthesizes these data and supplies the synthesized data to the D / A converter 15, where
15 converts the input data into an analog signal and outputs it to the image display device 16. The image display device 16 is a D / A converter 15
The display shown in FIG. 31A is performed based on the video signal from. As shown in FIG. 31A, in the first frame based on SOP (1), images P1 and P2 based on the images 1 and 2 and the display G1 based on the graphics (1) source data are displayed. I have. The display G1 is a button display shown in FIG.

On the other hand, the MPU 21 is a MIDI data demodulator 22.

When the user clicks the mouse 32 on the display G1, the link condition is satisfied, and the process proceeds to step S18.
After substituting the pointer 1 as the link destination pointer into the variable PT, the process returns to step S13. In step S13, SOP (2) which is the file of pointer 1 is read. Thus, in the next step S14, FIG.
The presentation based on SOP (2) shown in (b) is performed. Switching from frame 1 to frame 2 is performed by SOP
The slide-in method is adopted according to the link operation procedure described in (1).

On the other hand, if the mouse 32 is clicked on a portion other than the display G1, the link condition is not satisfied and the next step S
Move the processing to 19. In step S19, the window position / size (W (x, y, h, v)) described in each object operation procedure of SOP (1) is compared with the variable MP. That is, in step S19, it is determined whether the mouse 32 has been clicked on any of the image objects. If a click has been made on a portion other than on the images P1 and P2, the process proceeds from step S19 to step S15, where the process waits for a click operation. Now, when the user clicks the mouse 32 on the image P2, the MPU 21
Among the data contained in AOP (2) stored on AM12, the data types and all link types of all data files except for the data file of the already presented object are read, and a predetermined program programmed in MPU21 is read. Output to the graphics generation circuit 25 according to the format. The graphics generation circuit 25 outputs image data for displaying data of the data type and the link type in a menu format (menu button) to the synthesis circuit 27.

FIG. 32 is an explanatory diagram for explaining the display of the menu button.

The synthesizing circuit 27 synthesizes the image data for menu / button display with other image data and gives it to the A / D converter 15, and the image display device 16 outputs the output of the A / D converter 15 onto the screen. The menu button display shown in FIG. 32 is displayed (step S20). In AOP (2), as shown in FIG. 13, image attribute 2 source data indicated by data type A and AOP (3) indicated by link type continuous shooting are designated, and the menu button in this case is " The “photographing information list” and the “continuously shot image” are designated (see FIG. 32).

By clicking the menu button display with the mouse 32, the user can make a presentation based on these data that are not presented in the initial state. In steps S21, S22 and S23, the mouse 32 is clicked, and the cursor coordinates at the time of the click are substituted into a variable MP. Based on a comparison between the variable and the display position of the menu button, it is determined whether or not the menu button is clicked. Have judged. If a portion other than the menu button is clicked, the process returns to step S21 to wait for the click to occur, and if clicked on the menu button, it is designated by the menu button in the next step S24. Present the object.

For example, when the user clicks on the menu button for designating “list of photographing information” with the mouse 32, the MPU 21 moves the pointer 2 from the description of AOP (2).
Instruct the reproduction of the image attribute 2 source data recorded in 8. The MPU 21 provides the reproduction data from the optical disk device 5 to the graphics generation circuit 25 in a predetermined format. The graphics generation circuit 25 converts the given data into image data and supplies the image data to the synthesis circuit 27. Thus,
On the display screen of the image display device 16, a display A2 of attribute information indicated by a broken-line square mark in FIG.
A display such as a zoom magnification and a shutter speed is performed.

When the user clicks on the menu button for designating “continuously shot images” with the mouse 32, the MPU 21 obtains the AOP (3) recorded in the pointer 7 from the description of the link information of AOP (2). ) Is instructed to reproduce the data. As shown in FIG. 14, AOP (3) is a description of three types of data files indicated by data types P, A, and V. The designation of continuous shooting is for the second object of SOP (1), and the MPU 21
Instruct the reading of the image 3 source data indicated by the data type P among the data of (3). The optical disk device 5 reproduces the image 3 source data recorded on the pointer 21, and the SCSI controller 6 outputs the reproduced data to the JPEG decoder 13. Thereafter, an image P3 based on the image 3 source data is displayed at the display position of the image P2 by the same operation instead of the image P2.

Note that the voice data, like other data,
Presentation is managed by SOP and AOP. S
When the presentation of audio data is instructed by the OP or the AOP, the MPU 21 reads the specified audio data from the disk and transfers it to the buffer memory incorporated in the ADM demodulator 23. The ADM demodulator 23 demodulates the audio data in accordance with the reproduction instruction from the MPU 21 and outputs an audio signal to the synthesizing circuit 29. Thus, the sound based on the audio data is output from the speaker 31. For example, when the user clicks on the image P3 with the mouse 32, the graphics generation circuit 25 specifies "audio output" on the screen in addition to the menu button for specifying "photographing information list". Menu button (not shown)
Is also displayed. When the user clicks the mouse 32 on the menu button for designating “audio output”, the audio 1 source data recorded in the pointer 37 from the description of AOP (3) is reproduced by the optical disk device 5. . The reproduced data is supplied to an ADM demodulator 23 and converted into an audio signal. Thus, the environmental sound V1 before and after the image 3 is captured can be output from the speaker 31.

In this embodiment, another SOP can be specified as one object of the SOP, and an object of another frame can be presented as an object of a predetermined frame. For example, SOP (2) describes SOP (4) as the first object. As described above, the user can use the mouse 32 in FIG.
