3.7.2 Color Filter ID

The Color Filter ID register for Format 7 (see page 4-33) has been implemented on A601fc and

A602

fc cameras. This Color Filter ID register can be used to determine the alignment of the

camera’s color filter to the current Area of Interest (AOI). To use this feature, make all desired

changes to the camera’s parameter settings and then read the value in the Filter ID field of the

Color Filter ID register. The field will indicate an ID of 0, 1, 2, or 3 as appropriate.

As shown in Table 3-2, each ID identifies the color of the first two pixels in the first row of the

current AOI and the color of the first two pixels in the second row of the AOI. Due to the repetitive

nature of the Bayer RGB primary color filter (see Section 3.7.2) used in the A601

fc and A602fc, this

information is all you need to determine the order of the pixel colors with your current settings.

The actual range of valid settings for the Blue Value is from 16 (0x10) to 255 (0xFF),

however, only the settings from 64 (0x40) to 255 (0xFF) are useful. If you set the

Blue Value lower than 64 (0x40), the camera will continue to operate, but you will

see unacceptable changes in the color balance.

The actual range of valid settings for the Red Value is from 16 (0x10) to 255 (0xFF),

however, only the settings from 64 (0x40) to 255 (0xFF) are useful. If you set the

Red Value lower than 64 (0x40), the camera will continue to operate, but you will

see unacceptable changes in the color balance.

Table 3-2: Color Filter IDs

The Color Filter ID register for Format 7 is defined in version 1.31 of the IIDC spec-

ification.

Because the Color Filter ID feature is so new, the Basler BCAM 1394 Driver does not

yet include a method call to access this feature. As a work-around, you can use the

techniques described in the tutorial for the Basler Smart Features Framework Soft-

ware to directly read from or write to the Filter ID field.
