'Give us money, compensate us', they say, but since all of this was resolved by the Japan–Korea peace treaty, why are they reviving this issue? It's strange." It was subsequently reported by The Japan Times that on his first day at NHK Momii asked members of the executive team to hand in their resignation on

1272-546: The Von Kries transform simply by scaling the LMS coordinates by the ratio of the maximum of the tristimulus values at both white points. This provides a simple, but rough estimate. Another method that is sometimes preferred uses a Bradford transform or another chromatic adaptation transform ; in general, these work by transforming into an intermediate space, scaling the amounts of the primaries in that space, and converting back by

1325-475: The line of purples ), including colors described as white, can be produced by infinitely many combinations of spectral colors, and therefore by infinitely many different illuminant spectra. Although there is generally no one-to-one correspondence between illuminants and white points, in the case of the CIE D-series standard illuminants , the spectral power distributions are mathematically derivable from

1378-555: The 21st Director-General of NHK, caused controversy by discussing Japan's actions in World War II at his first press conference after being appointed on 20 December 2013.

By the late 1930s, NHK's overseas broadcasts were known as Radio Tokyo , which became an official name in 1941. In November 1941,

2491-457: The way this appears in the waveform, the higher black level is also called pedestal. This small difference doesn't cause any incompatibility problems, but needs to be compensated by a slight change of the TV brightness setting in order to achieve proper images. YIQ color encoding in NTSC-J uses slightly different equations and ranges from regular NTSC. I {\displaystyle I} has

2544-417: The white point is only related to color and unaffected by intensity). Illuminant and white point are separate concepts. For a given illuminant, its white point is uniquely defined. A given white point, on the other hand, generally does not uniquely correspond to only one illuminant. From the commonly used CIE 1931 chromaticity diagram , it can be seen that almost all non-spectral colors (all except those on

2597-451: The white points of the two illuminants. If the image is "uncalibrated" (the illuminant's white point unknown), the white point has to be estimated. However, if one merely wants to white balance (make neutral objects appear neutral in the recording), this may not be necessary. Expressing color as tristimulus coordinates in the LMS color space , one can "translate" the object's color according to

2650-500: Was enacted in 1950, which made NHK a listener-supported independent corporation and simultaneously opened the market for commercial broadcasting in Japan.
