PURPOSE:To obtain a circuit for finding out relation between a display area whose border is indicated by a clip frame on a display screen and a straight line to be displayed and relation between the klip frame and the straight line. CONSTITUTION:This clip tester circuit is constituted of a start point register 11 for storing the start point of a straight line, an end point register 12 for storing an end point, a klip frame register 13 for storing clip frame data, a comparing circuit 14 for comparing the data of the register 13 with the data of respective registers 11, 12, and a logical synthesis circuit 15 for synthesizing the outputs of the circuit 14. |
