Calculate HSV histogram of a coloured image is it different from H-S histogram?

edit

code to compute HSV histogarm .

 cvtColor( Frame, hsv_base, CV_BGR2HSV );
 int h_bins = 50; 
 int s_bins = 32;
 int v_bins = 10;
 int histSize[] = { h_bins, s_bins, v_bins };
 float h_ranges[] = { 0, 256 };
 float s_ranges[] = { 0, 180 };
 float v_ranges[] = { 0, 256 };
 const float* ranges[] = { h_ranges, s_ranges, v_ranges };
 int channels[] = { 0, 1, 2};
 calcHist( &hsv_base, 1, channels, Mat(), hist_base, 3, histSize, ranges, true, false);
