Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data file recording method and a data filing system for recording a plurality of information including image data on a recording medium, and more particularly, for example, a still image data such as a photograph to a large size such as an optical disc. The present invention relates to a data file recording method and a data filing system for recording on a recording medium having a capacity.

2. Description of the Related Art Conventionally, when still images such as photographs are managed, for example, at home, a plurality of photographs printed on photographic paper of a predetermined size are sequentially printed on each page of a book-shaped album. They were pasted and stored one by one. In this case, a plurality of images can be viewed for each page, and a desired image can be easily searched by sequentially turning the pages. Further, related images can be classified for each album, and it is possible to easily search for an album including a desired image by attaching a description or the like to each. However, as the number of photos increases, so does the number of albums, especially 10 or 2.
When the number of books increased to 0, there was a problem that the storage space was taken and the management became difficult. In addition, if these are stored for many years, the colors of the photographs have faded, and there are problems such as accidentally breaking the photographs when re-pasting them for organizing.

Therefore, in recent years, a still image such as a photograph is read by an image reading device such as a scanner, converted into digital data, each data is formed as a data file that can be displayed on a display device such as a display, and these are formed. An image recording system for recording on a large-capacity optical disc such as a compact disc (CD) has been developed. In this case, for example, each image file of the read image data is recorded on the optical recording medium together with the image data with keywords such as a file name, a photographer, a photographing date, and a title. Therefore, when reproducing, a target image file is searched by inputting a keyword such as a file name or a title. If there are multiple image files such as the photographer or the shooting date, enter this once to search for multiple image files, narrow down the target images with different keywords, and perform the work. I was looking for the target image by repeating.

Further, for example, Japanese Patent Application Laid-Open No. 05-181905 proposes a search information display device for recording an image taken by a digital still camera or the like on a memory card and searching the taken image from the card. . In this device,
When a small screen for a plurality of images is prepared, and when displaying a plurality of small images on the plurality of small screens, one representative image is displayed as a small image for a related image such as continuous shooting, and the search is performed. It was easy.

[0005]

However, in the above-mentioned conventional technique, when a large number of image files, for example, nearly 1000 image files are stored in one optical disk, it becomes as simple as a photo album. There was a problem that it became difficult to manage. In other words, when searching for a desired image using a keyword, for example, if multiple files correspond to one keyword, many different keywords are remembered until the target image file is obtained, and this is repeated multiple times. There was a problem that you had to enter it and could not search if you forgot the keyword. Also, it is possible to search for a desired image file only with small images, but even if you search for a desired image while scrolling a small screen against hundreds of image files, it takes time and effort. There is a problem in that it takes time and it takes time to find a desired image.

The present invention solves the above drawbacks of the prior art, and when a large number of images are recorded on a large capacity recording medium,
An object of the present invention is to provide a data file recording method and a data filing system that can be handled as easily as a photo album.
