Not sure what circular effect you are seeing, you might
try something like the following, it seemed to look like
bluring to me.

#local Blur_Image  = pigment {
  image_map {
    png "testimg.png"
  }
};
#local Blur_Left = pigment { Blur_Image translate <0.01,0,0>};
#local Blur_Right = pigment { Blur_Image translate <0,0.01,0>};
#local Blur_Up = pigment { Blur_Image translate <-0.01,0,0>};
#local Blur_Down = pigment { Blur_Image translate <0,-0.01,0>};
box {
  <0,0,0>, <1,1,0.001>
  texture { 
    pigment {
      average
      pigment_map {
        [1, Blur_Image]
        [1, Blur_Left]
        [1, Blur_Right]
        [1, Blur_Up]
        [1, Blur_Down]
      }
    }
    finish { ambient 0.3 }
  }
  translate <-0.5,-0.5,0> // center on the origin
}
