In a wipe pattern generator for generating a wipe pattern signal on the basis of wipe pattern data stored in a memory, data indicating a contour of a wipe pattern expressed by polar coordinates is stored in the memory, angle data and distance data indicating a position of each pixel on a monitor apparatus in a polar coordinate system is generated, data indicating the contour of the wipe pattern is read out from the memory on the basis of the angle data and a wipe pattern signal is formed on the basis of the read angle data and the distance data.
