TDA4VM: Question about LDC Lut mesh_img

Part Number: TDA4VM

Hi Ti's exports,

          I have a question about  the  Lens Distortion Correction (LDC) block. I saw the ldc  Supporting up to 8192 x 8192 image dimension. Our image size is 1280*5120. 

          According to the following instructions,the Bit width of signed integer offset in verical direction or horizontal direction only seems to be 12.

          That is, the maximum range that can support pixel translation is [-4096, 4096], am I right?

          Is there one way to expand the translation range?

          Can the precision be changed from 1/8th pixel to 1 pixel ?

  • There is no way to expand the range.

    The -4096 ~ +4096 offsets are relative to the output location.
    You may check if it is possible to limit your mapping so that the offsets are within the range.
