Abstract

PURPOSE:To detect the position of a ruled line without fail even when its image data are not horizontal or vertical, by collecting the value of an exclusive OR in a first axis direction, which is a ruled line direction, after executing the exclusive OR between picture elements adjoining to a second axis direction, which is the orthogonal direction to the first axis direction, out of the first and the second axis directions. CONSTITUTION:In a control circuit 17, an X counter 11 and a Y counter 12 are cleared, and a collecting counter 15 is also cleared with a terminal 15a. Thereafter, the contents of a first column RAM 33 and an image RAM 30 are read, and inputted to an exclusive OR gate 14, and the contents of the counter 15 is updated based on the output result. Next, the read contents of the image RAM 10 are written to the RAM 13, the X counter 11 is set at +1, and when the contents reach 2<l>, the contents are written to a projecting RAM 16, and the Y counter 12 is set at +1. Here, when the contents of the (y) counter reach 2<m>, an action is stopped, and the histogram projected on the (y) axis is stored in the RAM 16.
