Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image filing method, and more particularly, to a filing method for recording still image data on an optical disc and an apparatus therefor.

[0002]

2. Description of the Related Art Image data recorded on an optical disc of a so-called compact disc (CD) standard by Phillips Kodak Co., Ltd. has a standard size of 2048 × 3072 pixels for the number of pixels of an image on one screen. This image size is
This can be achieved with some high resolution film scanners. However, in the market, image data having various pixel numbers other than the standard size, that is, image sizes, is distributed through various media. For example, a standard television image such as an electronic still camera or NTSC has 4 pixels.
It is 88 x 640. Also, image data with 960 x 1280 pixels can be captured from so-called high-definition cameras. The new CD-I standard, which was also advocated by Sony Philips, can reproduce text information, images, and sounds.
It is a standard that focuses on so-called home appliances. This standard is an evolution of the conventional CD-ROM standard. These cds
-The number of pixels of images using various types of multimedia such as -I and home is 960 x 1280 pixels or less, which is equivalent to the number of pixels of images captured from the high-definition camera as described above.

When recording such various source images on a compact disc, it is considered that one source image is uniformly captured as one screen of the standard size and recorded and stored regardless of the size of the image. Be done.

[0004]

The standard size of the compact disc is a considerably large size as described above,
If one frame of various source images as described above is uniformly captured in the standard-size screen recording area of the compact disc, a large waste may occur. For example, the number of pixels obtained from a high resolution film scanner is 2048 ×
The image of 3072 corresponds to the above-mentioned standard size at a ratio of 100%. However, in the case of images captured from a high-definition camera or CD-I, or standard television images obtained from an electronic still camera, the respective ratios to the standard size are only 20% and 5%, respectively. Moreover, among the image data actually recorded and stored in the compact disc, the image having a high storage frequency is expected to be an image having a small number of pixels such as a captured image from a high-definition camera or a standard television image.

Therefore, when the image data acquired from a high-definition camera or a standard television image medium is stored in the standard size of the compact disc and recorded and stored in the compact disc, a considerably large margin is left in the standardized memory area. And it is expected that the editing will be inefficient. This situation induces not only the problem of memory utilization efficiency, but also the problem of providing staggered images that are visually visually tight.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks of the prior art and to provide an image filing method and apparatus capable of reproducing an image with good visibility.

[0007]

Storing image data representing a first image of at most the image size in a storage area, and capturing image data representing a second image smaller than the image size in the storage area,
Combining the second image with the first image as a background;
Recording the combined image data as image data of the image size on the optical disc in a recording format.

According to the present invention, an image filing apparatus for recording image data on a compact disc standard optical disc in a compact disc standard recording format represents at most a first image having an image size of one screen of the recording format. First storage means for storing image data, input means for receiving image data representing a second image smaller than the image size, and second storage having a storage area capable of storing image data of at least the image size Means and the first and second storage means are controlled so that the image data representing the first image is read out from the first storage means and expanded in the storage area to represent the second image received by the input means. A synthesizing means for synthesizing the second image with the first image as a background by fetching the image data into the storage area, and the image data of the synthesized result. And recording means for recording on the optical disk in a recording format data as image data of the image size.

[0010]

According to the present invention, the image data representing the first image is stored in the storage area, the image data representing the second image is taken into this storage area, and the second image is set with the first image as the background. And the resulting image data is recorded on the optical disc in the recording format as image data of the image size. As a result, the first part of the screen may become a margin on the screen in the recording format of the compact disc.
Image is captured and the visibility of the image is improved.

The image data editing device 11 includes a hard disk I (HD I) 12 and a hard disk for executing an editing function.
A II (HD II) 14, a temporary storage memory 16, an operating device 18 having a keyboard and / or a mouse, and a monitor display 40 such as a CRT. The hard disk I12 stores a processing program for executing the editing process in the editing device 11, and this is also used as a storage area for holding image data during or after the editing process. This processing program is read into the temporary storage memory 16 when the power of the apparatus is turned on. The hard disk II 14 is used as an area for storing various data necessary for editing a source image, that is, a main image obtained from the image data sources 30 and 20. This various data includes standard size plain screen, background 160 such as colored paper pattern and background image, frame 150 such as picture frame, title 170, and data representing the illustrations and words 180 created by the user (Fig. 2). Including. Although these various data are referred to as image data for convenience of description, they are used as auxiliary images to be combined with the main image. Although the image size of the auxiliary image is basically the standard size in the present embodiment, the frame 150, the title 170, and the phrase 180 may have various sizes smaller than the standard size forming part of the standard size. Good. As will be described later in detail, the user can select these auxiliary images as needed.

The operating device 18 is a monitor display device described below.
In relation to 40, it is a selection command input unit for selection and guidance displayed on the monitor display 40. Further, the device 18 is an input unit for inputting an auxiliary image originally created by the user, for example, a new title, an illustration, a recorded phrase, and trimming, moving, and
It is also a means for inputting operation instructions such as frame setting. The monitor display 40 is a device that displays various image information relating to image processing to the operator, such as system status, processed images, and guidance of processing procedure options. The hard disks I 12 and II 14 are shown as including not only the recording medium but also a drive device for the recording medium. Moreover, in each figure, the same components are denoted by the same reference numerals.

In this embodiment, the compact disc 52 is
The optical disc is a write-once optical disc of the Sony Philips standard, and the image data recorded on the optical disc is stored in the standard size described above, that is, in a format that constitutes one screen 200 (FIG. 2) with 2048 × 3072 pixels. This image size is
This is the same as the image size of the image obtained from some high resolution film scanner (not shown). The apparatus of this embodiment records an image having an image size other than the standard size represented by the image data obtained from the high-definition camera 20 and the memory card 32 on the compact disc 52 in the standard size format. At that time, if a single screen image of an image size other than the standard size is simply assigned to a single screen of the standard size of the compact disc format, a large margin will occur in the storage area. Therefore, in the present embodiment, when an image of a size other than these standard sizes is recorded as the main image, another image or (and) character data or other auxiliary image is combined and edited in the area 160 that is originally a margin. Compact disc 52
To record. The editing device 11 also performs a process of combining the recording data of the main image and the auxiliary image into a single screen (FIG. 4).

In the operating state, for example, a memory card
The image data decompressing device 30 is loaded with 32, and desired image data is read from the memory card 32. This instruction operation is performed by operating the operation device 18 while watching the display on the monitor display 40. In response to this, the image data decompressor 30 responds to the card
The image data of one frame image 130 recorded in 32 is read (300, FIG. 4), and this is expanded and decoded. This image data is taken into the editing device 11 and temporarily stored in the temporary storage memory 16. The editing device 11 displays an image represented by the image data recorded in the temporary storage memory 16 on a monitor display.
Display on 40 display screens. The operator can input various image processing instructions by operating the keyboard or mouse of the operating device 18 while viewing this image. In response to this, the editing device 11 performs image processing 301 such as color and density correction on the image data in the memory 16. The image data of the processed main image is stored in the hard disk I12 (302).

Then, the user operates the operating device 18 in accordance with the display on the display 40 to select the auxiliary image as the background of the main image 130 (303). This auxiliary image is used for background images such as standard size plain screens, colored paper patterns and background images.
Selected from. Alternatively, a frame image such as a standard-size frame may be used. For example, if the main image is a photograph of a family at the seaside, it is good to select a landscape photograph of the sea or an ukiyo-e print of Hodogaya in Katsushika Hokusai as the background image of the image. When the auxiliary image 160 is specified by the operation device 18, the editing device 11 responds to this and the hard disk II 14
The corresponding auxiliary image 160 data is retrieved from and expanded into the standard-size storage area of the temporary storage memory 16 (30
Four). The entire auxiliary image 160 is visually displayed on the display 40.

The image data editing device 11 then proceeds to the main image currently being processed, that is, in step 302, the hard disk I.
The image data of the main image 130 saved in 12 is read into the storage area of the temporary storage memory 16, and the auxiliary image already developed in this area, that is, the background image 1 in this example.
Synthesize to 60 (305). The resulting standard size image 200
Becomes as shown in FIG. At that time, in the system of the present embodiment, the operation device 18 is operated to operate the image area 2 of the standard size.
The fitting position of the main image 130 at 00 can be selected. If there is no additional image to add to this (3
10), the editing device 11 compresses and encodes the image data of the resultant composite image 200 expanded in the temporary storage memory 16.
(311). Compressed and encoded image data is on the hard disk I
It is stored in I 14 (312).

In step 310, when adding another auxiliary image, the operation device 18 is operated to specify and select a desired auxiliary image. This auxiliary image may be, for example, a frame 150 such as a frame smaller than the standard size, a title 170, and an illustration or a word 180 created by the user. In response to this, the editing device 11 absorbs the image data of the selected auxiliary image from the hard disk II 14 and expands it in the storage area of the composite image 200 in the temporary storage memory 16.
(320). The state is displayed on the monitor display 40, and the operator can also operate the operating device 18 to specify the arrangement position of the auxiliary image in the standard-size image area 200. A standard size image 200 in which the frame 150, the title 170, and the illustrations and phrases 180 are combined is shown in the lower part of FIG.

In this embodiment, a general-purpose auxiliary image is registered in the hard disk II 14, and if necessary, it is selected and used. For example, title 170, commentary 180
An auxiliary image that the operator wants to create, such as an illustration, can be created by the editing device 11 by operating the operation device 18. For example, the commentary 180 can be created using the operation device 11 by the same operation as a word processor. In this way, the auxiliary image 170 or the like created by the operator is taken into the temporary storage memory 16 and further combined with the combined image already developed therein (320). It should be noted that the created image data can be recorded and stored in the hard disk II 14.

In this way, the user operates the operating device 18,
Single or multiple images stored on the memory card 32
Each of the image data of 130 can be read from the card 32, subjected to the image processing 301 of the main image, and a desired auxiliary image can be combined with this and stored in the hard disk I12 in a compression-coded form. This is done by manipulating the operating device 18 to cycle through the loop including step 330. Similarly, for the image data of the source image 120 obtained from the high-definition camera 20, the auxiliary image can be combined and stored in the hard disk I12.

In this way, the edited standard size edited image 200 is completed on the hard disk I12 for a desired frame. In the present embodiment, the image data editing apparatus 11 uses the standard size editing screen 200 as a unit for 24 sheets.
We will now create a compact disc image file in the standard file format (ISO9660) using the CD-ROM authoring system (332). The created file data is sent to the CD writer 20, and the CD writer 20 writes this to the compact disc 52, and thus the CD to the disc 52.
-The ROM image file is completed.

The edited image 200 finally recorded on the compact disc 52 may include images from various image data sources such as the memory card 32 and the high-definition camera 20 as a matter of course. Also, the source image as the main image to be edited is not limited to one image, but a plurality of images of standard size
It may be effective to edit it on one screen of 200. For example, a standard size seaside image may be used as the background image 160, and a plurality of standard TV size person images 130 taken on the beach may be appropriately scattered and edited.

[0025]

As described above, according to the present invention, when an image of a small size is captured and recorded and stored on a screen having a large image size of the compact disc standard, the play portion generated in the recording area of the recording medium is effectively utilized. Therefore, it is possible to reproduce an image with good visibility. In addition, it is possible to easily edit an image that is personally preferred, and an effect of improving diversity is obtained by recording information other than the image on one screen.
