Forum Post: How to set "Gain Table Address Base(upper/lower)" in DM368 LSC (Lens Shading Correction) ?

I want to use LSC(Lens Shading Correction) in DM365/DM368.

But after I set reigster setting for LSC, it appears on image with no change.

I think it depends on how to set Gain/Offset Table Address Base register.

1. Can you tell me how to set Gain/Offset Table Address Base register in detail?

- Unlike other module, this block has no LUT(look up table) memory space.

  Do I have to use spare memory space for Gain/Offset Table in DDR2 memory?

2. How to make Gain Table? Do I have to make Gain Table value using some math formula?

3. How does the LSC do work using only 128 point Gain Table? or 128x3rows table?

    - I think 128 point Gain Table covers 1 Horizontal line in image.

      for example, in 1280*720 image,I think LSC Gain Table covers 1280 * 1 image. (1 Horizontal row image).

      But about 720, Can the LSC Gain Table cover ?
