[0002]

2. Description of the Related Art Conventionally, there are the following systems for retrieving digital video materials. As the first conventional method for searching for digital video materials, VOD
Large and decentralized databases such as the Internet and the Internet
When searching a peripheral device type database such as a D-ROM or an MO, keyword information such as a name and a genre to which digital video materials stored in these databases are added in advance and used. 2. Description of the Related Art There is known a method in which a user inputs a word indicating keyword information of a digital image to be searched using text, and extracts a digital image material corresponding to the word.

Further, as a second conventional method of searching for digital video materials, instead of inputting words, keyword information is expressed on a screen using small figures such as logos and icons, and those small figures are selected. Then, there is a method of searching for a digital video material.

Further, as a third conventional method of searching for digital video materials, digital video materials are hierarchically classified according to display parameter display types, and search parameters are selected one after another for each search parameter display type to navigate. There is a search method that gates and arrives at the digital video material to be searched.

FIG. 10 shows an example of a third conventional method for retrieving a digital video material. In the method shown in the figure, three digital images X30, digital images Y31, and digital images Z32 are each searched for on one search screen. That is, the digital video that the first search screen 10 can directly search is the digital video X30, the digital video that the second search screen 11 can directly search is the digital video Y31, and the third search screen 12
Digital video that can be searched directly is Digital Video Z
32. When searching for the digital video Z32, the search is performed by sequentially changing the search screen from the first search screen 10 to the second search screen 11, and further from the second search screen 11 to the third search screen 12.

Further, as a fourth conventional method of searching for a digital video material, as a method of reducing the number of transition search screens, a method of scrolling search parameters using a plurality of small windows in one search screen. There is.
FIG. 11 shows an example of a fourth conventional method for searching for digital video materials.

In the example of FIG. 1, a fashion item of a model appearing for searching for a fashion image and three search parameter display types of eye color and hairstyle are displayed as text on one search screen. In the search parameter display type A20, "flare skirt" is selected as the fashion item, in the search parameter display type B21, the eye color "blue (BULE)" is selected, and in the search parameter display type C22, the hairstyle "Belly short" is selected. Is selected. Further, by scrolling, other display types can be selected by various search parameters.

[0008]

However, according to the first conventional method for searching for digital video materials, the user remembers the digital video materials to be searched in the form of images such as shapes, colors, designs and textures. If the user does not remember the word indicating the keyword information, it is necessary to search for a word that is as close to the image as possible and repeatedly perform the search. For this reason, since the image cannot be directly searched, there is a problem that the number of searches increases and the search efficiency decreases.

In the second conventional method for searching for digital video materials, when the number of functions on the search screen is increased, the number of small graphics increases, and the area ratio of graphics increases. To address this, we ’ll increase the number of search screens,
There is a problem that the cost for screen design increases.

The third conventional method for searching for a digital video material is shown in FIG.
0, digital video Y31, and digital video Z32, only one search display type is displayed on one search screen.
Search can be performed on one search screen.
Search, the first search screen 10, the second search screen 1
Transition of three search screens of the first and third search screens 12 is required. Specifically, on the first search screen 10, the digital video X30 is determined by selecting a parameter of the search parameter display type A20. The digital video Y31 and the digital video Z32 cannot be determined only by the parameters of the search parameter display type A20, so it is necessary to transit to the second search screen 11 and select the parameters of the search parameter display type B21. The digital video Y31 is determined by selecting two parameters, the search parameter display type A20 and the search parameter display type B21. However, the digital video Z32 cannot be determined even with these parameters, and a transition to the third search screen is required. Become.

In the search method shown in this example, when the number of search screens for transition and the number of paths increase, the number of search screens transitions, and the search takes time. For this reason, there is a problem that search efficiency is reduced depending on the number of screens. Further, in the fourth conventional method of searching for digital video materials, parameters such as color and shape are directly displayed as text as shown in search parameter display type B21 and search parameter display type C22 in FIG. However, there is a problem that an actual image is difficult to recognize. Furthermore, since it is a non-endless display method called a scroll type, the first parameter and the last parameter cannot be displayed continuously and repeatedly in one window, so that a search is performed based on ambiguous memory. In such a case, there is a problem that it takes time to solidify the image of the memory, and the efficiency of the search is reduced.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a video material search method and apparatus capable of solving the above conventional problems and efficiently searching for digital video materials. And It is another object of the present invention to provide a video material search method and apparatus capable of directly searching for an image even when a digital video material searched by a user is stored as an image.

A further object of the present invention is to provide a video material search method and apparatus capable of reducing the area ratio of a figure on a search screen. A further object of the present invention is to provide a video material search method and apparatus in which there is no complicated screen transition and the number of transition screens and paths do not increase even if the amount of accumulated material increases. .
