%X The development and present situation of drawing circle algorithm are introduced，and to point out the faults by empirical analysis and summarizing for Bresenham’s algorithm and Kuzmin’s algorithm.Then，a new algorithm chooses the best approximate pixels to the circle with only integer arithmetic，based on the double-step circle drawing algorithm of Wu and Rokne.Finally，the new drawing circle’s algorithm with different grey scales is proposed.It generates 3 intermediate shades of grey scale than the double-step algorithm by Wu and Rokne，and the greatest error of intensity is reduced 1/4.These algorithms are easy to be performed by hardware.
