Abstract

In a DB retrieval method, a two-step retrieval including quantitative and qualitative retrievals is interactively performed so that, through the operation of image information (e.g. map information) having a correspondence to a DB having text information such as attribute information stored therein, attribute information corresponding to the map information is retrieved from the DB. The quantitative retrieval includes a DB information reading process for reading image information, attribute information and information relevant thereto, and a quantitative retrieval process for making a quantitative retrieval including the partial overlaying of another information for retrieval on the original image information (or map information) or a rough retrieval with the other information used as a retrieval key called information lens, and storing the result of retrieval into a work file. The qualitative retrieval includes a DB information reading process for reading image information, attribute information and information relevant thereto, which are stored in the work file, and a qualitative retrieval process for making a qualitative retrieval in which the original image information (or map information) is overlaid with a retrieval key called a function sheet including the composition of a qualitative retrieval condition and an image indicative of a range of application of the retrieval condition, and displaying the result.

Claims

1. A method for retrieving in a database through image information, comprising the steps of:

(a) reading a first image information of a database in which text information linked with the first image information is stored from a storage device

(b) retrieving said text information corresponding to a specified area of a second image information linked with and displayed overlaying said first image information displayed on a display device from said database on the basis of a first user instruction from an input device and storing the retrieved text information into a work file together with said first image information corresponding to said retrieved text information; and

(c) composing a retrieval condition and an area range of application thereof as an image data on the basis of a second user instruction from said input device, retrieving text information corresponding to said image data displayed overlaying said first image information displayed on said display device from said work file, and outputting the result of retrieval to said display device.

2. A method according to claim 1, further comprising the steps of:

(d) repeatedly performing said steps (a) to (c) or said step (c) c the basis of an instruction for changing image information, text information or a retrieval condition from said input device by the user.

3. A method according to claim 1, wherein said step (b) further includes the substeps of:

(b1) displaying said first image information on said display device;

(b2) changing display format of an image of a specified area of said second image information linked with said first image information on the basis of said first instruction from said input device and displaying the changed image in a composite form with said first image information; and

(b3) retrieving text information corresponding to the changed image from said database stored in said storage device in a form linked with said first image information.

4. A method according to claim 1, wherein said step (c) includes the substeps of:

(c1) composing image data with a retrieval condition represented by text format and an image representing an area range of application of said retrieval condition on the basis of an instruction from said input device by the user;

(c2) displaying said image data overlaying said first image information on said display device; and

(c3) retrieving text information corresponding to said retrieval condition composed in said image data from said database stored in said storage device in a form linked with said first image information.

9. A method according to claim 3, wherein in said substep (b2), a magnified version of said specified area of said second image information including another kind of information is composed in a local area on said first image information, said local area corresponds to said specified area of said second image information.

10. A method according to claim 3, wherein in said substep (b2), said specified area of said second image information including another kind of information is composed in a local area on said first image information and within area range in which a distance from a center position set by the user is predetermined.

11. A method according to claim 3, wherein in said substep (b2), a modified version of a part of said second image information including another kind of information is composed in a local area on said first image information by use of the correspondence of said first image information to said second image information to be composed thereon.

12. A method according to claim 1, wherein in said step (c), a plurality of image data each of which is composed with different retrieval condition and area range of application thereof are displayed overlaying said image information displayed on said display device on the basis of an instruction from said input device by the user, text information corresponding to the result of a logical operation defined by said different retrieval conditions and area ranges included in said plurality of image data is retrieved from said work file, and the result of retrieval is outputted to said display device.

5. A method for retrieving in a database through image information, comprising the steps of:

(a) reading a first image information of a database in which text information linked with the first image information is stored from a storage device;

(b) displaying said first image information on a display device;

(c) changing display format of an image of a specified area of second image information linked with said first image Information on the basis of an instruction from an input device and displaying the changed image in a composite form with said first image information; and

(d) retrieving text information corresponding to the changed image from said database stored in said storage device in a form linked with said first image information.

6. A method according to claim 5, further comprising the steps of:

(e) repeatedly performing said steps (a) to (d) on the basis of a user instruction for changing image information, text information or retrieval condition from said input device.

7. A method for retrieving in a database through image information, comprising the steps of:

(a) composing image data with a retrieval condition represented by text format and an image representing an area range of application of said retrieval condition on the basis of an instruction from said input device by the user;

(b) displaying said image data overlaying said image information on said display device; and

retrieving text information corresponding to said retrieval condition composed in said image data from said database stored in said storage device in a form linked with said image information.

8. A method according to claim 7, further comprising the steps of:

(d) repeatedly performing said steps (a) to (c) on the basis of a user instruction for changing image information, text information or retrieval condition from said input device.
