TECHNICAL FIELD OF THE INVENTION
The present invention relates to an image recording medium creating system for creating an image recording medium by recording image data on the recording medium, and an image recording medium created by the system.
[0002]
[Prior art]
2. Description of the Related Art Generally, an image captured by a digital camera is recorded and stored as image data on a CD. According to this, images such as photographs can be stored for a long period of time without deteriorating the quality of the images, and when a photograph is taken, approximately several hundreds of image data can be recorded on a single CD. Images can be stored. The above-mentioned image data is once stored in a compressed state on a memory card for a digital camera, and is usually stored on a CD in the compressed state. As this compression method, for example, a JPEG (Joint Photographic Experts Group) method is adopted.
[0003]
In addition to storing a still image as described above, a moving image can be stored on a CD. For example, there is a VCD (Video CD) for reproducing moving images on a CD. The storage of the moving image data in the VCD can be performed by compressing the moving image data by an MPEG (Moving Photographic Experts Group) method, particularly a method conforming to the MPEG-1 method. Note that if the moving image data is such that the same frame is displayed continuously for at least a certain period of time, an image that looks stationary, such as an image such as a photograph, can be reproduced. Accordingly, moving image data in a form in which a plurality of still images (for example, compressed by the JPEG method) shot by a digital camera or the like are displayed sequentially (in a sliding manner) for a predetermined period of time, It can also be recorded on a VCD.
[0004]
[Problems to be solved by the invention]
However, even if moving image data in which the same still image is continuously displayed is stored on a CD as described above, the resolution is much lower than that of a DVD or the like. The reality is that only a relatively low-resolution still image called a dot is displayed.
[0005]
In view of such a problem, the present invention provides an image recording medium creating system capable of storing high-quality moving image data on a CD that is less expensive than a DVD disk or the like, and an image recording medium created by the system. The task is to
[0006]
[Means for Solving the Problems and Functions / Effects]
In order to solve the above problems, an image recording medium creation system according to the present invention includes: a still image data reading unit that reads JPEG still image data compressed by a compression method conforming to the JPEG method from an external device;
A moving image in which a still image based on JPEG still image data is defined as one frame, and moving image data of a moving image in which a frame having the same image as the frame is continuously displayed for at least a certain period of time is created from the JPEG still image data. Data creation means,
Image recording medium creating means for recording the created moving image data on a compact disk (CD) as an image recording medium;
An image recording medium creating system having
The moving image data creating means creates moving image data such that a still image is displayed with a resolution in a range of more than 240 × 352 dots and 480 × 780 dots or less.
[0007]
According to the configuration of the image recording medium creating system as described above, a still image is stored as a moving image in which the same image is continuously displayed, and the moving image data of the moving image is stored on a compact disc (CD). At this time, a compact disc whose resolution of the moving image is comparable to that of a DVD can be created. That is, the resolution of a still image (moving image that appears to be still) can be improved as compared with the conventional VCD, and a higher quality (DVD-like) still image can be displayed on a monitor or the like with a cheaper compact disc. It can be displayed on a display device. The moving image data recorded on the CD is such that a plurality of still images based on a plurality of JPEG still image data read from an external device such as a digital camera or a scanner are sequentially displayed for a predetermined period of time. It can be. Accordingly, various still images can be displayed in a slide format. For example, a series of events (for example, a child's growth record or the like) can be stored separately on one or a plurality of CDs. .
[0008]
Further, the moving image data creating means may create the moving image data as MPEG moving image data compressed by a compression method conforming to the MPEG method. In the compression method conforming to the MPEG method, one frame is intra-coded and compressed in the time axis direction by motion compensation inter-frame prediction, so that still images are displayed continuously, that is, When compressing moving image data that does not have a difference between the data, very efficient data compression is performed. Therefore, when a still image is continuously displayed for a certain period of time as in this case, the resolution of the still image can be improved.
Further, since the moving image data is recorded on a compact disc (CD) by a method conforming to the MPEG method, the CD can be reproduced by a reproduction apparatus compatible with the MPEG method such as a DVD player. Therefore, with a compact disc as an image recording medium created by the image recording medium creating system of the present invention, a video can be enjoyed on a home television via a DVD player or the like. The moving image reproduced based on the MPEG moving image data is such that still images based on a plurality of JPEG still image data are sequentially (slidably) reproduced at regular intervals.
[0009]
Further, in the image recording medium creating system, the image recording medium creating means may record the JPEG still image data together with the moving image data on a CD. In this way, if JPEG still image data compressed by the JPEG method is also stored as image data on an image recording medium such as a CD together with moving image data, for example, via a DVD player or the like, In addition to watching a moving image based on MPEG moving image data on a home television, a personal computer or the like can view or edit a still image based on JPEG still image data. That is, with one CD, images can be enjoyed on two types of devices, a home television and a personal computer.
[0010]
Further, the image recording medium of the present invention created by the image recording medium creating system of the present invention has an image as a compact disc on which moving image data of a moving image in which a still image is continuously displayed for at least a certain period is recorded. A recording medium,
The moving image data is characterized in that a still image is displayed at a resolution in a range of more than 240 × 352 dots and 480 × 780 dots or less.
Such an image recording medium which is a compact disk (CD) of the present invention is very inexpensive as compared with a DVD disk, and can reproduce high-quality images comparable to a DVD. Further, the recorded moving image data may be, for example, an image photographed by a digital camera or the like, or an image such as an old photograph that has already been printed out, which is sequentially displayed for a certain period of time. .
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
First, FIG. 1 is a block diagram illustrating an outline of an image recording medium creation system according to the present embodiment. The image recording medium creating system 100 shown in FIG. 1 includes a computer 112 having a CPU 102, a ROM 103, a RAM 104, and an HDD 105. The computer 112 has input / output devices such as a memory card slot 106 (hereinafter, referred to as a slot 106), a scanner 108, a monitor 109, a printer 110, and a CD recorder 111 via the I / O port 101. Are connected to form an image recording medium creation system 100 according to the present invention. A memory card 107 can be inserted into the slot 106, and image data (A.jpg, A.jpg, JPEG still image data) of an image captured by, for example, a digital camera (not shown) is stored in the memory card 107. B.jpg, C.jpg...) Are stored. These image data (A.jpg, B.jpg, C.jpg...) Are stored in a state where the JPEG compression processing is performed by the digital camera body. Note that there are various types of memory cards 107, and the slot 106 into which the memory card 107 is inserted adopts a type suitable for each type. The memory card 107 may be attached to an adapter corresponding to the memory card 107 and inserted into the slot 106.
[0012]
Further, in a RAM 104 in the computer 112, a data creation program work area 104a, an image data (JPEG) memory 104b, an image data editing memory 104c, a voice data memory 104d, a character data memory 104e, an application memory 104f, and an editing program work area 104g are provided. , An image data (MPEG) memory 104h, and the like. Further, in the HDD 105, music data 1, music data 2, music data 3,... Are stored as audio data.
[0013]
Next, a procedure for creating an image recording medium by the image recording medium creating system 100 of the present invention will be described with reference to FIGS. Although the case of a CD-R is shown as an image recording medium, a CD-RW may be used. First, the power of the computer 112 is turned on, and the application of S1 in FIG. 3 is started. Here, the image data recorded on the memory card 107 is read out from the slot 106, and after deleting / adding and editing the image, the image data of the MPEG system is created from the image data of the JPEG system. The processing until the created MPEG moving image data (MPEG) is written on the CD is performed on the application started in S1. When the application starts, an operation screen of the application is displayed on the monitor 109 in FIG.
[0014]
After the processing in S1, it is determined whether or not the memory card 107 is inserted in the slot 106 (S2). If it is determined that the memory card 107 is not inserted into the slot 106, the memory card 107 in S3 is inserted into the slot 106. At this time, a display for prompting insertion of the memory card 107 into the slot 106 is displayed on the monitor 109. On the other hand, when it is confirmed that the memory card 107 is inserted into the slot 106, a screen for selecting the type of the memory card 107 is displayed on the monitor 109, and the type of the memory card 107 inserted this time is selected on the screen. (S4).
[0015]
The selection of the memory card 107 can be performed by an operator touching a corresponding position on the selection screen with a finger or a dedicated support bar (touch panel function). Note that all operations such as addition, deletion, and editing of images described below can be performed by touching the screen displayed on the monitor 109 with a finger or a dedicated support rod.
[0016]
In S4, if it is confirmed that the same type as the memory card 107 inserted in the slot 106 is selected on the selection screen, the JPEG still image data (A.jpg, B.B) stored in the memory card 107 is confirmed. .Jpg, C.jpg ...) is read (S5). The process of S5 is performed by the CPU 102 based on a data reading program attached to the above-described application software stored in the ROM, for example. At this time, the above-described data reading is performed by searching only the image data (JPEG image data) compressed by the JPEG method from the image data stored in the memory card 107 and reading only the JPEG image data. Set the program. The read JPEG image data is recorded on the HDD 105 shown in FIG. 1 and temporarily stored in the image data (JPEG) memory 104b of the RAM 104. Then, as shown in FIG. 2A, images (1, 2, 3,...) Based on each image data (A.jpg, B.jpg, C.jpg,...) Are collectively monitored. Displayed at 109 (S6). The data reading program and the CPU 102 constitute a still image data reading unit.
[0017]
Subsequently, in S7, it is determined whether or not image data has been added. If image data has been further added, an add button 109d in FIG. 2A is selected, and the process proceeds to the above-described step S3. As a result, the JPEG still image data stored in another memory card 107 newly inserted into the slot 106 is stored in the RAM 104 together with the previously read JPEG still image data as shown in FIG. Is temporarily recorded in the image data (JPEG) memory 104b. Then, an image based on the added JPEG still image data is displayed on the display screen 109a of FIG. 2A together with the previously read image.
[0018]
On the other hand, if the image data is not to be added any more, it is determined in S8 whether to edit the image. When editing an image, the following various editing operations are performed (S9). First, when characters are to be added to each image, an image for which characters are to be edited is selected on the display screen shown in FIG. Specifically, after pressing an edit button 109e displayed on the operation frame 109b of the display screen 109a, an image to be edited is selected from the displayed images (1, 2, 3,...). When the selection of the image to be edited is completed, only the selected image is large and displayed on the display screen 109a of the monitor 109 as shown in FIG. 2B (FIG. 2B shows a case where image 1 is selected). Is shown on the display screen 109a). When characters are to be added to the image 1, the user selects a desired color that matches the image 1 in the color selection area 109g displayed on the operation frame 109b, and uses a finger or a dedicated pointing stick to display a character on the display screen. , Characters are appropriately added to the image 1. When adding a character, a desired character is selected by selecting an appropriate line thickness from the line thickness area 109i or appropriately selecting an eraser 109h or the like (in some cases, changing the line color). Can be formed. In addition, not only characters but also decorations and the like can be given to images. When the editing is completed, a save button 109j is selected to end the editing operation.
[0019]
In the case of the present embodiment, objects such as characters or image decorations given by the editing operation are set as object data (for example, bitmap data) D1 different from the JPEG still image data as shown in FIG. As shown in (1), the image data is stored in the image data editing area 104c in a form corresponding to each JPEG still image data jpg.
[0020]
When an unnecessary image is to be deleted, the user selects the delete button 109c in the operation frame 109b on the display screen shown in FIG. It can be performed by selecting with the support rod of the above. For an image determined to be unnecessary by this selection, a display (for example, an X mark) indicating that the image is to be deleted is given on the display screen. Note that by selecting an image selected as unnecessary with a finger or a dedicated support rod again, the deletion of the image can be canceled. At this time, as shown in FIG. 4B, for determining whether to record the image in a form corresponding to the JPEG still image data jpg recorded in the image data (JPEG) editing area 104c. The recording determination data D2 is created. In FIG. 4B, a case where an image is recorded (when the image is not deleted) is represented by 0, and a case where the image is deleted (when the image is not recorded) is represented by 1. When the MPEG moving image data is created, only the data whose recording determination data D2 is 0 are read.
[0021]
Further, in the image editing process in S9, the order of the still images reproduced in the moving image can be changed. That is, on the display screen 109a of FIG. 2A, the order button (109f) displayed on the operation frame 109b is selected, and then the images whose order is to be changed are selected. Then, while the image to be replaced is selected, the user selects the “previous” or “next” button 109 k in the operation frame 109 b as appropriate to move the selected image on the display screen, and in a desired order. Can be set. At this time (or when the editing operation is completed), as shown in FIG. 4B, based on the set order, the image order data D3 is formed in a form corresponding to each JPEG image data jpg.
[0022]
When a series of editing as described above is completed, an end button 1091 in the operation frame 109b is selected on the display screen of FIG. As a result, the image editing operation is completed, the display screen shown in FIG. 2A is closed, and subsequently, a selection screen for urging the user to determine whether to add background music (BGM) to the created moving image is displayed. (For example, a display such as "Do you want to add BGM?", "Yes", or "No"). Here, it is determined whether or not to add background music (BGM) to the created moving image (S10). If BGM is to be added, a plurality of music data (audio data) recorded on the HDD 105 shown in FIG. The music data 1, music data 2, music data 3,... Are read out (S12), and information (for example, title, playing time, etc.) of the music data is displayed on the display screen 109a. Thus, the user can select his or her favorite music by referring to the information of the plurality of displayed music data. When the music (BGM) is selected, the music data of the selected music is temporarily recorded in the music data memory 104d of the RAM 104. Note that the audio data is not limited to music, but may be a voice such as a human voice, an animal squeal, or a noise.
[0023]
If the reading of the music data as described above (S12) is not completed or BGM is not added to the moving image, it is considered that all editing operations have been completed, and the music data is stored in the image data editing area 104c. , JPEG still image data jpg, MPEG moving image data is created by data creation means. At this time, for example, a data creation program (not shown) stored in the ROM 103 is read out by the CPU, and the program can be started in the data creation program work area 104 a of the RAM 104. That is, in the case of the present embodiment, the CPU 102 and the data creation program serve as moving image data creation means. As shown in FIG. 4 (b), the moving image data creating means includes the JPEG still image data jpg recorded in the image data editing area 104c, the object data D1, the recording determination data D2, and the image order. Based on the data D3, MPEG moving image data (X.mpg) is generated such that still images based on the JPEG still image data jpg are displayed in the selected order as shown in FIG. I do. The created MPEG moving image data is temporarily recorded in the image data (MPEG) memory 104h of the RAM 104 (S11). Note that the moving image data creating means creates moving image data for displaying the still image at a resolution of 480 × 704 dots.
[0024]
As described above, when the MPEG moving image data is created, the created MPEG moving image data is recorded on a CD-R as an image recording medium. First, as shown in FIG. 3 and S13, it is confirmed whether a CD-R is inserted into the CD recorder 111 shown in FIG. If no CD-R is inserted into the CD recorder 111, a display prompting the user to insert the CD-R into the CD recorder 111 is displayed on the display screen of the monitor 109. When the CD-R is inserted into the CD recorder or when the CD-R is inserted in S14, a confirmation display for confirming whether the MPEG moving image data can be recorded on the CD-R is displayed on the display screen of the monitor 109. If the user selects to record, MPEG moving image data is recorded on the CD-R by the image recording medium creating means (CD recorder 111) (S15). At this time, JPEG still image data and music data 1 (when music data 1 is adopted as BGM) are recorded on the CD-R together with the MPEG moving image data. As for the JPEG still image data jpg, only the data used for creating the MPEG moving image data (X.mpg) based on the recording determination data D2 shown in FIG. ) Can be recorded.
[0025]
FIG. 5 briefly explains the created CD-R as an image recording medium together with various data recorded on the CD-R. As described above, the CD-R contains not only MPEG moving image data (stored in MPEG.DIR) but also JPEG still image data (stored in JPEG.DIR) and music data (music.DIR). Stored) is recorded. The MPEG moving image data is linked to the music data. When the CD-R of the present invention is reproduced by a reproducing apparatus compatible with the MPEG system, such as a DVD player, the music is linked to the moving image based on the MPEG moving image data. BGM based on the data will be reproduced. The moving image based on the MPEG moving image data is reproduced in a slide type in which the still images based on the JPEG still image data are displayed one after another at regular intervals in a selected order. More specifically, in the case of MPEG moving image data recorded on the CD-R in FIG. After the still image A ′ based on the J.jpg is reproduced at regular intervals, B. jpg, C.I. Still images B ′ and C ′ based on jpg are sequentially reproduced at regular intervals.
[0026]
Also, the JPEG still image data recorded on the created CD is edited as a normal still image data by a personal computer (for example, a home personal computer), an image output on a monitor is viewed, or an e-mail is output. It can be utilized by a known method such as transmitting an image by the above method.
As described above, in the image recording medium creation system 100 of the present invention, a slide show of a still image can be enjoyed on a television (for example, a home television) via a playback device conforming to the MPEG system such as a DVD player, and By using a personal computer or the like, it is possible to create an image recording medium on which a user can enjoy image editing, image viewing, and the like based on JPEG still image data, using a cheaper CD (CD-R, CD-RW).
[0027]
The image recording medium creating system of the present invention as described above can create a CD capable of reproducing a moving image in which a still image having a resolution of 480 × 704 dots is continuously displayed by a DVD player. The JPEG still image data that is the basis of the moving image data is not limited to the one read from the memory card 107 as in the above embodiment. For example, as shown in FIG. 1, a scanner 108 is employed as an external device connected to the computer 112, and the scanner 108 reads a still image as still image data (JPEG still image data) compressed by the JPEG method. MPEG moving image data can be created from the JPEG still image data. Specifically, an image of a photograph that has already been printed out (developed) can be captured by the scanner 108 and stored on a CD as MPEG moving image data and JPEG still image data.
[0028]
Also, a CD drive 113 is connected to the computer 112, and JPEG still image data stored in a CD (photo CD, CD-R, CD-RW, etc.) inserted in the CD drive 113 is read, and as described above. MPEG moving image data can be created and recorded on another CD (CD-R, CD-RW). Note that the CD drive 113 and the CD recorder 111 can be configured as an integral unit.
[0029]
The image recording medium creating system 100 as described above is installed in a place such as a photo shop, a convenience store, a wedding ceremony hall, a leisure facility, etc., and maximizes its effects. When installed in a photo shop or convenience store, instead of providing a service to record images of old photos as JPEG still image data and MPEG moving image data on CDs, instead of printing out images taken with digital cameras, A service of recording the image data on a CD (or in addition to printing out) can also be provided. On the other hand, by installing the system in a place such as a wedding hall or leisure facility, it is possible to provide services such as distributing a CD created by the system of the present invention as a memorial to attendees or tourists of the ceremony. . In addition, for participants and tourists of the ceremony, images taken by the participants and tourists of the ceremony are saved on a CD while performing various editing on the spot where the mood is uplifting. A service that can be viewed on the spot can be provided.
[0030]
Further, the image recording medium creation system 100 of the present invention can be made portable. In this way, it can be easily installed in a sightseeing bus, for example. By installing the image recording medium creating system 100 of the present invention in a sightseeing bus, the following services can be provided. That is, the image data of the image captured by a tourist or tour operator with a digital camera at a tourist spot (the tour operator can lend a digital camera to the tourist, or use his / her own digital camera). While traveling to the next sightseeing spot, a CD can be recorded on a CD in a sightseeing bus in a compression system conforming to the MPEG system, and the created CD can be distributed to tourists. In addition, a DVD player and a television are installed in the sightseeing bus, and the created CD is reproduced by the DVD player, so that the image just taken by the digital camera while the sightseeing bus is moving can be used as a slide type.
