Camera timing behavior is like this:

Packed 12-Bit Mode

All Stingray cameras have the so-called Packed 12-Bit Mode. This means:

two 12-bit pixel values are packed into 3 bytes instead of 4 bytes.

The color codings are implemented via Vendor Unique Color_Coding accord-

ing to IIDC V1.31: COLOR_CODING_INQ @ 024h...033h, IDs=128-255)

See Table 112: Format_7 control and status register on page 249.

Fast Parameter Update Timing Quick Format Change Mode (QFCM)

After sending a new parameter value, the changed

parameter value is valid for the available next

image. Frame rate is constant.

After sending a new parameter value, the changed

parameter value is valid for the available next

image.

A running exposure will be interrupted and the

image is dropped.

There may be a gap between two consecutive

image transfers.
