PROBLEM TO BE SOLVED: To provide a reference signal pattern capable of visually confirming which video parameters are used by a video apparatus, in an ultra-high definition television video system.SOLUTION: A reference signal pattern for use in an ultra-high definition television (UHDTV) video system has a first region not included in a colorimetric system defined by BT.709 gamut, and having a first color included in a wide color gamut colorimetric system defined by BT.2020, or has a lamp pattern where the luminance increases at a rate of 1 gray scale per 1 pixel in a video of 12 bit gray scale, or has a region where a region of horizontal stripe structure of 1 pixel wide, a vertical stripe structure of 1 pixel wide, and white lines and block lines draw a spiral shape.SELECTED DRAWING: Figure 1 |
