To establish a simulation technology for estimating and predicting radio propagation characteristics with short calculation time and high accuracy, we have proposed a novel color images method (CIM) based on processing colors images of walls of buildings which are seen from a transmission and reception points. However, the estimation performance of the proposed CIM has not been sufficiently clarified. In this paper, we compare the CIM with Wireless InSite (WI) employing a conventional ray tracing method (RTM) in terms of percentage of estimable reception points, estimation accuracy, and calculation time. Comparison results show that for the same percentage of estimable reception points, the average value and root mean squared error (RMSE) of path loss estimation errors of the CIM are -0.8 dB and 8.3 dB, respectively, and much smaller than those of the WI with 15.9 dB and 21.7 dB. Moreover, the calculation time of the CIM is 0.0089 times shorter than that of the WI in case of changing conditions of the transmission point.
