In order to inhibit blooming and prevent degradation in the capability of projecting thin blood vessels, the luminance basically increases as power P becomes high. However, when there are two sampling points identical in power P but different in variance V in a region low in power P (P<=P1), the luminance of a pixel corresponding to the sampling point relatively large in variance is set higher than that of a pixel corresponding to the sampling point relatively small in variance V.
