'''This still need to be figured out:''' | |||
We will address the MakerNote byte array as 'mnote' (i.e. mnote[0] is the first byte) | |||
There is a dynamic byte array at first which its size is at mnote[9]. | |||
After the dynamic array starting at mnote[6 + mnote[9]] an 88 bytes array starts. | |||

What is known that on mnote[mnote[9]+72] & mnote[mnote[9]+73] lays the parallax value. | |||
The parallax value is the distance that the right image needed to move in order to get focus. | |||
My formula to get that value isn't so good but here it is: | |||
b0 = mnote[mnote[9]+72] | |||
b1 = mnote[mnote[9]+73] | |||
x = (b1 - 0xC0) << 8 + b0; | |||
Parallax = - round( 2 ^ (x/128 + 2) ) | |||
If someone makes sense of this, please explain or maybe correct.. | |||
