Hi, I want to know PREVIEW block. I tried set the table of  "Non-Linear Luminance Enhancement", "Noise Filter", and "CFA filter coefficient". But there is no any information in SPRU977d. Please tell me about these functions.

Non-Linear Luminance Enhancement Table

  1. What's the input of this block. 
  2. What's affect of "Offset" and "Slope".
Noise Filter
In SPRU977d, filter is 3x3 grid of same color pixels. But the number of filter table is  0xFF. Why i need to set the rest of 246's register?
CFA filter
There is no data for this block. Please tell about the details of this block.
 
Sincerely,

    I got the information about Non-Linear Luminance Enhancement Table in PSP driver's document.
    That's very wrong place to write explanation.
    Please write this information to Datasheet or User's guide.
    if you know the information about CFA and NF table,  please tell me.
