Abstract
A wipe pattern generation apparatus that can generate wipe patterns of various shapes at high speed and moreover can be miniaturized. is provided. A wipe pattern generation apparatusincludes a sin θ generation sectionfor calculating sin θ from input angle information θ; a multiplierfor multiplying the calculation result of sin θ by a first coefficient; a cos θ generation sectionfor calculating cos θ from the angle information θ; a multiplierfor multiplying the calculation result of cos θ by a second coefficient; a multiplierfor multiplying the result of adding output of the multiplierand output of the multiplierby a third coefficient and outputting as the reciprocal of the distance from the polar coordinate center to an arbitrary line on a display screen; a multiplierfor multiplying output of the multiplierby distance information r; and a comparatorfor making a comparison between output of the multiplierand a fourth coefficient, and generates wipe pattern output datafrom the angle information θ and the distance information r.
