Abstract

There is an image information searching apparatus for analyzing the character information in the image information inputted from an image inputting apparatus and producing search information to search the image information. This apparatus comprises: a scanner to scan a recording medium such as a microfilm or a recording paper in which image information was recorded; this image information including discriminating information to discriminate this image information or a plurality of image information of the same group from another image information; a dictionary information memory section in which dictionary information such as a standard pattern of a character or a numeral to recognize the discriminating information was stored; a recognition controller to recognize the discrminating information using the dictionary information; and an image information memory section to store the recognized discriminating information as search information together with the image information corresponding thereto.

Claims

1. An image information searching apparatus comprising:

a cassette for containing therein a recording medium in which a plurality of portions of image information have been recorded, a first portion of the image information including character information for discriminating the plurality of portions of image information in said cassette from those in another cassette;

determining means for determining whether said cassette has been attached to said apparatus;

scanning means for scanning the entire first portion of image information recorded in the recording medium when said determining means determines that said cassette has been attached to said apparatus;

first memory means for storing the image information read by said scanning means;

second memory means for preliminarily storing a character pattern; and

character deciding means for reading out the image information stored in said first memory means and the character pattern stored in said second memory means and for recognizing the character information for discrimination included in the image information stored in said first memory means.

2. An apparatus according to claim 1, wherein said cassette is a cassette to enclose microfilms, papers or the like.

3. An apparatus according to claim 1, wherein said character information is discriminating information to discriminate the image information included in the same category as the image information from another image information.

4. An apparatus according to claim 1 further comprising output means for outputting the result of said character deciding means.

5. An apparatus according to claim 1, wherein said scanning means also detects the attachment and detachment of said cassette.

6. An image information searching system comprising:

determining means for determining whether a cassette storing image information therein has been attached to said system;

scanning means for scanning an entire first portion of a group of the image information, the first portion of the group of the image information including discriminating information for discriminating the group of the image information from another group, when said determining means determines that the cassette has been attached to said system;

recognizing means for recognizing the discriminating information included in the group of image information obtained by a scan by said scanning means;

modifying means for performing editing of the discriminating information recognized by said recognizing means; and

image information memory means for storing the discriminating information edited by said modifying means and image information corresponding to the edited discriminating information.

7. A system according to claim 6, wherein said scanning means scans the image information.

8. A system according to claim 6, wherein said modifying means is an input section which can input a desired pattern information.

9. A system according to claim 6, wherein the discriminating information recognized by said recognizing means, the information obtained by editing the discriminating information, and the corresponding image information are stored in said memory means by correlating the recognized discriminating information, the edited information and the corresponding image information.
