JPS5692684A - Reading-in and processing system for graph sectioning - Google Patents

Abstract

PURPOSE:To prevent the production of missing in advance, by finding out the scheduled area of duplicated read-in for the 1st and 2nd sectioned graph and inputting it to the 2nd sectional graph. CONSTITUTION:Near the boundary of graph sectioned, the video data read in at the sectioned graph 2-1 is stored to the buffer register 5-1, and the sectional graph 2-2 is stored in the buffer register 5-2 sequentially storing the video data. According to the new input of the video data for one line's share for the registers 5-1 and 5-2, the similarity is calculated at the similarity calculator 6. Further, if it is detected that the similarity is not reached to the threshold value, the alarm generator 8 produces alarm. Further, the selection circuit 13 outputs agreement signal to the output from the similarity nonsingle peak detector 10 and outputs the detection signal from the similarity single peak detection section 9 for other cases. Thus, the presence of the duplicated reading scheduled area 3 is found and input to the sectional graph 2-2, allowing to prevent the production of missing in advance.
