PROBLEM TO BE SOLVED: To improve the utility value of an electronic data base by separating and extracting the character and segment information out of the dot information of an image data form and converting these extracted information into the codes and managing these codes by a text file of high utility value. SOLUTION: This system consists of an electronic file medium 30, a paper medium 20, a scanner 8, a segment/character separation part 13, an editing device 2, a recording medium 9 and a retrieval device 11. The part 13 receives the image data from the medium 30 or the scanner 8, normalizes with thinning of lines the image data into an (N-dot×M-dot) size, allocates the normalized image data to 1000 types of vertical, horizontal, upper right oblique and upper left oblique line elements, divides these allocated image data into (A×B) areas to compare them with a character symbol dictionary J5 which is previously produced and stored, and then separates in sequence the divided areas into the segments and the character symbol/photo images by extraction of features in order to discriminate the directional line element feature value by the multi- dimensional vector out of the image data.
