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 you can enter a value in the range of 1 to 4095.

Guppy PRO cameras use a time base which is multiplied by the shutter regis-

ter value. This multiplier is configured as the time base via the TIMEBASE reg-

ister.

The time base IDs 0-9 are in bit [28] to [31]. See Table 116: Time base ID on

page 224. 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 35ff.
