Area correction factors can be registered for a total of 10 groups to the BM-7A. Groups 1 to 5
are assigned to area correction factors for the xy chromaticity diagram, and groups 6 to 10 are
assigned to area corrections factors for the u'v' chromaticity diagram. Also, it is possible to set
5 chromaticity areas in 1 group. In the chromaticity area setting, the correction factors are
specified by KX, KY and KZ, and the minimum and maximum areas of application of correction are
specified by x, y, or u' ,v', and minimum Luminance are specified by L. When performing setting
of CM-700 on the PC side, area correction factors can be registered for a total 40 groups.
Groups 1 to 20 are assigned to area correction factors for the xy chromaticity diagram, and
groups 21 to 40 are assigned to area correction factors for the u'v' chromaticity diagram.
