ranges to generate the 16-bit codes. However, since
the human eye is more sensitive to Green, we can give
Red and Blue 5 bits each, with 6 bits for Green, and
each cell in the image gets replaced by its index. This
may lead to edge artifacts in the image. Therefore, this
is not suitable for natural images but may be suitable
for artificially created images.
PIC24FJ256DA210 supports up to a 256-entry CLUT
with 16 BPP per entry.
Median Cut Algorithm
Note:
A color index refers to one row of CLUT.
It is an adaptive method that tries to put most bits where
A simple color changing type of animation process is
possible by changing the CLUT in the above method.
This is also known as palette animation.
In the above explanation, we saw a simple way to
cluster the image and device a CLUT, but clustering is
a slow process.

colors are most clustered, so that they can be discrim-
inated. This is the most general algorithm used while
converting a RGB image to a CLUT-based color image,
such as PC applications (e.g., GIMP).
