Image database apparatus and method of controlling operation of same
First Claim
1. An image database apparatus comprising:
- an extraction device for extracting representative image data, which represents representative images of a plurality of frames, from an image database in which image data of a number of frames has been stored;
a first display control device for controlling a display device in such a manner that the representative images of the plurality of frames represented by the representative image data extracted by said extraction device are displayed in a two-dimensional coordinate area in a form in which they are distributed in accordance with characteristics of each of the representative images;
a designating device for designating a desired image from among the images of the plurality of frames distributed in the two-dimensional coordinate area based upon display control performed by said first display control device;
a search device for searching the image database for images having characteristics that resemble the characteristics of the image designated by said designating device; and
a second display control device for controlling the display device in such a manner that retrieved images, which result from the search performed by said search device, are displayed in the two-dimensional coordinate area whose coordinates axes are more detailed than coordinate axes in the two-dimensional coordinate area in which images are displayed in a form in which they are distributed based upon display control by said first display control device, in conformity with the characteristics thereof, whereinthe second display control device is configured to control the display device to display in the two-dimensional coordinate area, whose coordinates axes are more detailed than coordinate axes in the two-dimensional coordinate area under control of the first display control device, a number of retrieved images that result from the search performed by the search device that is equal to the number of the plurality of frames displayed in the two-dimensional coordinate area under control of the first display control device.

Abstract
Ten representative images are extracted from an image database storing images of a number of frames. The extracted representative images are displayed in a coordinate area, along the coordinate axes of which the image characteristics of the images are plotted, in a form in which the images are distributed in accordance with the image characteristics possessed by the extracted representative images. An image having characteristics resembling those of a required image is designated from among the representative images displayed. Images of ten frames having characteristics resembling those of the designated image are again displayed in distributed form in a coordinate area having image characteristics plotted along the coordinate axes thereof. The coordinate axes of the coordinate area displayed the second time are made more detailed than those of the coordinate area displayed the first time. As a result, images having slightly different characteristics are displayed in separated form, thereby making it easier to find the required image.

7. A method of controlling operation of an image database apparatus, comprising the steps of:
-
(a) extracting representative image data, which represents representative images of a plurality of frames, from an image database in which image data of a number of frames has been stored; (b) displaying the representative images of the plurality of frames represented by the extracted representative image data on a display device in a form in which the images are distributed in a two-dimensional coordinate area in accordance with characteristics of each of the representative images; (c) designating an image of a desired frame from among the images of the plurality of frames distributed in the two-dimensional coordinate area; (d) searching the image database for images having characteristics that resemble the characteristics of the image designated; and (e) controlling the display device in such a manner that retrieved images, which result from the search, are displayed in the two-dimensional coordinate area whose coordinates axes are more detailed than coordinate axes in the two-dimensional coordinate area in which images are displayed in a form in which they are distributed based upon display control by said first display control device, in distributed form, wherein step (b) is carried out by a first display control device and step (e) is carried out by a second display control device, and the second display control device is configured to control the display device to display in the two-dimensional coordinate area, whose coordinates axes are more detailed than coordinate axes in the two-dimensional coordinate area under control of the first display control device, a number of retrieved images that result from the search performed by the search device that is equal to the number of the plurality of frames displayed in the two-dimensional coordinate area under control of the first display control device.
