Sharpness strength

b(3:2)Reserved
b(1:0)LABB control:
  • 0h: Disabled
  • 1h: Enabled: Manual strength control
  • 2h: Reserved
  • 3h: Reserved

The key function of the LABB is to adaptively gain up darker parts of the image to achieve an overall brighter image.

For LABB strength, 0 indicates no boost applied and 255 indicates the maximum boost viable in a product. The strength is not a direct indication of the gain, since the gain varies depending on the image content.

Sharpness strength ranges from 0 to 15, with 0 indicating sharpness disabled and 15 indicating the maximum sharpness. The LABB function must be enabled to make use of sharpness.

LABB is supported in TPG, splash, and external input mode, but auto-disabled in curtain mode.
