Abstract
PURPOSE: To cut out and read characters from a complicated background, by cutting out them by detecting existence of parameters of characters.
CONSTITUTION: In respect to the binary picture from picture memory 3, screen C where the point equal to character height H is defined as 1 is obtained by character height region detecting circuit 10. Next, screen D where the part equal to the line width of the character is defined as 1 is obtained by segment detecting circuit 11. The whole of the screen is divided into blocks correspondingly to the size of characters, and the number of points of 1 is obtained in each block of screens C and D. It is decided that characters exist in the block where numbers of points of 1 are a prescribed value or more. Blocks where existence of characters is decided are obtained, and a region is so taken that these blocks are included, and thus, the range of character existence is cut out.
