Memory Layout for 1-/2-/3-field Configurations

Memory layout of the metadata as delivered in the MultiCam surface

The memory layout vary according to the:

  • The metadata configuration: 1-field, 2-field or 3-field
  • The pixel type: monochrome, Bayer CFA or RGB
  • The pixel bit depth
  • The ImageFlipX setting

The following rules are applicable:

  • Metadata are replacing entirely all bytes of one or several pixels. Gaps, if any are filled with 0
  • When ImageFlipX=OFF the metadata replaces the first pixel(s) of the image line
  • When ImageFlipX=ON the metadata replaces the last pixel(s) of the image line

Notice also that:

  • When ImageFlipy = ON, the first line with metadata appears at the bottom side of the image (i.o. the top side)
  • When TapGeometry = *_1Y2, only one line every two contains metadata.
  • When TapGeometry = *_2YE, only the lines belonging to the upper (ImageFlipX = Off) or the lower(ImageFlipY=ON) half region contain metadata.
