Appendix B: Blue Correction Command
Note: This command applies to the PC-30-0xK80 cameras only.
The 80 mega-pixel camera models (PC-30-02K80 and PC-30-04K80) show an artifact at
the mid-point of the blue taps. The blue correction command enables replacing these
pixels with interpolated values.
Affected pixels:
Model 1st Blue Tap 2nd Blue Tap
PC-30-02K80 516, 517, 519, 520 1536, 1537, 1539, 1540
PC-30-04K80 1025, 1026, 1028, 1029 3067, 3068, 3070, 3071
The interpolation equation is as follows and includes green pixel data:
Blue: [B1][B2][B3][B4]
Green: [G1][G2][G3][G4]
B2 = G2 + ((B1 – G1) + (B4 – G4)) / 2
B3 = G3 + ((B1 – G1) + (B4 – G4)) / 2
if (B <= 0)
B = (B1 + B4) / 2
if (B > 4095)
B = 4095
This value is saved with the WUS command.
This value may be viewed on the GCP screen or with the GET EBC command.
