Bayer Decoder
Grablink Quickpack CFA acquires color images that were encoded with a Bayer color filter. The CFA decoder block can decode these data.
Take note of the following CFA characteristics:
- The CFA decoder is automatically enabled when the selected camera belongs to the BAYER Color class, and the selected output format requires either the RGB or the Y component.
- The parameter CFD_Mode selects the algorithm used by the CFA decoder. Two modes are available on Grablink Quickpack CFA: ADVANCED and LEGACY.
- The default setting of CFD_Mode is ADVANCED. The selected algorithm is based on a 3x3 interpolation and a median filter. This algorithm is an improved version of the LEGACY algorithm, especially in the transitions.
- The alternate setting of CFD_Mode is LEGACY. The selected algorithm is based on a 3x3 interpolation.
- The CFA decoding is performed at full pixel data accuracy.
- The CFA decoder speed performance is independent of the selected algorithm. The CFA decoder speed performance is sufficient to feed the board output stage without introducing a performance limit.
