TE259用于檢查波形監(jiān)視器上廣播攝像機(jī)的動態(tài)范圍。

在灰色背景（D = 1.35）上排列兩個(gè)20級分度的逆流灰度級，灰度級不是對數(shù)級的，也不是線性的！ 相對于最亮補(bǔ)片測量密度。

The TE259 is designed to check the dynamic range of broadcasting cameras on a waveform monitor. Two 20-step graduated counter current gray scale are arranged on a gray background (D = 1.35), the gray scale is NOT graduated logarithmically nor linear! Densities are measured relative to the brightest patch.
