Maximum resolution
This register indicates the highest resolution for the sensor and is read-only.
Time base
Corresponding to IIDC, exposure time is set via a 12-bit value in the corre-
sponding register (SHUTTER_INQ [51Ch] and SHUTTER [81Ch]).
This means that a value in the range of 1 to 4095 can be entered.
Guppy cameras use a time base which is multiplied by the shutter register
value. This multiplier is configured as the time base via the TIMEBASE regis-
ter.
The time base IDs 0-9 are in bits 28 to 31. See Table 116: Time base ID on
page 263. Refer to the following table for code.
Default time base is 20 µs: This means that the integration time can be
changed in 20 µs increments with the shutter control.
Note

This register normally outputs the MAX_IMAGE_SIZE_INQ
Format_7 Mode_0 value.
This is the value given in the specifications tables under
Picture size (max.) in Chapter
Specifications on page 29.
