Look-Up-Table Block
The look-up-table block uses the output of the histogram generating block and the segmentation block to generate
a conversion function for the improvement of dynamic range. It is composed of the histogram integrating block,
look-up-table generating block, and the look-up-table 2nd differentiation.

Look-Up-Table 2nd Differentiation
Luminance Expander
The luminance expander receives the LUT value from the look-up-table block and stores it in line memory. It also
moves the address by 1 and stores it in a different line memory. The LUT values stored in the two line memories
are put through temporal and spatial interpolation to receive data with an expanded band zone for luminance
signals.

Temporal interpolation
Spatial interpolation
8-bit division for gain calculation
Expanded luminance signal output feature
Chrominance Expander
The chrominance expander receives the outputs of the preprocessing block and the luminance expander, adjusts
the color difference signal according to the ratio between the expanded and non-expanded luminance signals, and
outputs the expanded chrominance signal. It also adjusts the color data's sensitivity according to the the band zone
of the luminance signal.

Color data sensitivity adjustment according to luminance signal band zone
Adaptive LPF Block
The adaptive LPF block receives the output of the chrominance expander, reduces high frequency components
such as noise in areas with little change in the grey level, and emphasizes edge and other minute details. It also
uses a high pass filter to extract the edge of the image.
