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.
