Title: Table structure extracting device
Inventor: RI SHIGETAKA
IPC: G06T7/00
Filed: 1993-12-22
Abstract: PURPOSE:To provide a table structure extracting device which can properly and accurately extract the ruled lines, the intersecting points, etc., out of the printed documents and also can omit the pre-processing for correction of the tilt. CONSTITUTION:A black pixel string detecting part 12 scans the compressed binary date and detects the horizontal and vertical black pixel strings. A segment extracting part 13 constructs the paths by the continuous horizontal vertical black pixel strings which are adjacent to each other and extracts the horizontal and vertical segments on both paths by a straight line deciding rule. A ruled line candidate constructing pert 21 successively detects the continuous horizontal and vertical segments adjacent to each other by a method that detects the next adjacent segments to the present segments based on the overlapping between both segments end the continuous black pixel strings adjacent to each other. Then the horizontal and vertical ruled line candidates are obtained from detected horizontal end vertical segments respectively. A table structure extracting part 31 checks the crossing between the rectangular intersecting point candidates to the vertical ruled line candidate on the basis of the horizontal ruled line candidate and vice versa. Thus the genuine intersecting points and the genuine horizontal end vertical ruled lines are acquired.

Title: Shading distortion correction circuit
Inventor: OSHITA KAZUAKI
IPC: H04N1/40
Filed: 1987-12-22
Abstract: PURPOSE:To eliminate mis-transmission of an original by comparing an analog picture signal representing a white level by one line of the original with a setting voltage by a comparator one by one picture element each and multiplying a control voltage with each picture element respectively so as to correct the shading distortion. CONSTITUTION:An analog picture signal representing a white level of one line amplified by a voltage controlled amplifier 3 is compared by a comparator 4 one by one picture element and a count command is inputted to a FF circuit 6 from a control circuit 7. The comparator 4 converts an analog picture signal into a binary picture signal. On the other hand, the binary picture signal via the FF circuit 6 is led to a NOT circuit 12 via a changeover switch 11, where the binary picture signal outputted from the comparator 4 is converted into an inverted signal. The inverted signal is given to an integration circuit 13, which gives a control voltage to correct the shading distortion to the voltage controlled amplifier 3.
