The develpoment of high-speed algorithm using Dual Lines Scanning, called DLS for perimeter measurement of the figures of binary image is described in the previous report. Also it is proved theoretically that the accuracy of the measurement with that algorithm is increased by employing rectangular pixel of large vertical-to-horizontal ratio in the same report. This time, the algorithm is implemented in a simple hardware and the measuring characteristics are evaluated for vasious shapes of figures. The experimental results closely agree with the estimation by the computer simulation made beforehand. There are two ways for realizing rectangular pixel with large vertical-to-harizontal ratio in the present raster scanning video system. They are increasing the horizontal or decreasing the vertical resolution respectively. It is confirmed experimentally that the accuracy of measurement is improved even in the latter case, in which the total resultion is decreased. As the result of experimental investigation, it is proved that the DLS algorithm is practically effective for the perimeter measurement of figures.
