Image Quality and Color Management Technologies in the LH Series LCD Monitors for Broadcasting Use
The color space on LCD displays tends to narrow when the
luminance level drops, and it's often accompanied by color
phase shifts that cause colors to drift. 3D-LUT (Look Up Table)
Color Correction on the LH Series LCD monitors includes a
look up table for each luminance level, and applies 10 bit
image processing to each RGB color to balance the six
coordinate poles of the three primary colors (RGB) and
their complementary colors (CMY). This solves the problem
of color drifting at low luminance levels, and keeps colors
vividly natural.
In addition to enhancing low luminance areas, 3D-LUT Color
Correction helps to produce finely nuanced intermediate hues.
Based on color measurements in the intermediate color parts
of the image, this function applies smooth correction
processing while balancing the six coordinates of the three
primary colors (RGB) and their complementary colors (CMY),
resulting in beautifully smooth gradation. It keeps the
intermediate shades of extremely fine colors vibrant and lifelike.
