This is a chromaticity diagram display function corresponding to colorimetry ITU- R BT. 601, ITU- R BT. 709, ITU- RBT. 2020. The display mode corresponds to CIE 1931 (xy display) and CIE 1976 (u'v' display).

Since the CIE chart display function can display two color gamuts, the function can be used to suppress the color gamut of BT.709 using the equipment compatible with BT.2020 and to confirm the content that exceeds the color gamut of BT.709. In a color display, the chromaticity point is displayed using the color (on the picture) in the video signal. The chromaticity point can be measured at the point with the cursor.
