摘要： PURPOSE:To detect a character segmenting position with high accuracy by correcting the estimated character pitch in accordance with the relative position relation between a segmenting end candidate position and a black block. CONSTITUTION:A pitch estimating means 14 and a block correcting means 15 are provided to correct the estimated character pitch in accordance with the relative position relation between segmenting end candidate position and a black block. Thus the segmenting position is detected with high accuracy even if an error is produced between the estimated character pitch and that of a character string pattern. In addition, the characters are arranged in many general printed documents with a fixed pitch or an approximately fixed pitch with some variance. As a result, the character segmenting position can be detected with high accuracy based on an estimated character pitch with a document where the characters are arranged especially with a fixed or approximately fixed pitch.

摘要： PURPOSE:To quickly and highly accurately segment a character by segmenting a character pattern from a character-string pattern, based on segment start and segment end positions. CONSTITUTION:A pre-processing means 10 obtains a character-string pattern, and a block extracting means 12 detects an initial position and a terminal position in the character-string position of a black block of the character-string pattern. A segment position detecting means 14 detects an estimated character pitch of the character-string pattern, detects a position separated by roughly an estimated character pitch from a segment start position as a segment end cadidate position, and decides whether the segment end cadidate position is positioned in the black block or not. Subsequently, in accordance with a result of decision, a determination of the segment end position and a correction of the estimated character pitch are executed, and based on the segment end position, the next segment start position is set. A segmenting means 16 segments a character pattern from the character-string pattern, based on the segment start and segment end positions. In such a way, a character can be segmented quickly and with high accuracy.

摘要： PURPOSE:To eliminate the dispersion of an AGC output by converting an analog input signal from a read sensor into a digital signal so as to apply digital processing thereby facilitating the setting of the AGC characteristic. CONSTITUTION:An analog signal from a read sensor 1 is converted into a 6-bit digital signal by an A/D converter 2 and outputted to a comparator circuit 3. The comparator 3 reads the 6-bit value subjected to A/D conversion to discriminate whether or not it is 111111(3F). In case of 3F, the address is incremented by one at the address counter 4. The information to increase a reference voltage is written in the content of the memory 5 when the address is increased. The value read out of the memory 5 is converted into an analog signal by a D/A converter and it is applied as a reference voltage of the A/D converter 2 to apply the gain control.

摘要： PURPOSE:To collate fingerprints with high positioning accuracy by determining a superposed position between a collating fingerprint and a registered fingerprint based on line number distribution and line width distribution obtained from a binary graphic pattern. CONSTITUTION:A collating pattern obtained from a reading part 11 is stored in a collating pattern memory 12. Registered patterns are previously stored in a registered pattern memory 13. The memories 12, 13 are scanned by a raster method in 1st and 2nd directions and the line number distribution and line width distribution of both the patterns are respectively extracted by a line number distribution extracting part 14 and a line width distribution extracting part 15. The line number distribution is compared with the line width distribution by a reference point extracting part 16 and a superposed position of both the patterns is extracted. A coincidence deciding part 17 superposes the collating pattern to the registered pattern based on the superposed position, finds out the degree of coincidence of both the patterns and decides the coincidence or discrepancy of both the patterns based on the degree of coincidence.

摘要： PURPOSE:To accurately detect the reference point of a graphic by determining the reference point of the graphic based on the distribution of lines extracted from a binary graphic pattern obtained by reading out a graphic and storing the graphic in a pattern memory. CONSTITUTION:A reading part 11 reads out a graphic and stores the graphic pattern in the pattern memory 13. A line distribution extracting part 15 reads out graphic patterns stored in the pattern memory 13 line-sequentially in 1st and 2nd directions and counts up the number of segments to find out the number of lines in each scanning and form the distribution of lines in the 1st and 2nd directions. A reference point detecting part 17 finds out the reference point of the graphic based on the line distribution formed by the extracting part 15.

摘要： PROBLEM TO BE SOLVED: To grasp series of movement of object in an image as a whole while almost fixing arithmetic quantity in spite of size of movement by providing the information of movement in inputted moving image data based on the information of stripe-shaped patterns. SOLUTION: A space/time axis transforming part 10 inputs moving image data S101, stores these data, transforms the coordinate system of moving image data expressed on a three-dimensional space and outputs a pattern S102 on a two-dimensional space to a projection pattern preparing part 102. The projection pattern preparing part 102 inputs the twodimensional pattern 102, projects it for each of plural directions and outputs a projected pattern S103 to a stripe direction detecting part 103. The stripe direction detecting part 103 inputs the projected pattern S103, calculates its variance for each direction and outputs the direction of maximum covariant value as stripe direction data S104 to a moving amount output part 104. The moving amount output part 104 inputs plural pieces of stripe direction data S104, calculates the amount of movement corresponding to the moving image data S101, and outputs moving image movement data S105.
