5.1 Region of Interest

The full resolution of the camera is 2096 pixels by 1184 lines.You might program a smaller reso-

lution in order to reduce the readout time. You must be careful that depending on the

sequencing mode, the exposure time can be reduced too.The authorized values for horizontal

size are 32 to 2096 pixels. This value is rounded to the lower multiple of 16 pixels. The autho-

rized values for vertical size are 32 to 1184 lines. This value is rounded to the lower multiple of 9

lines. See registers ROI area @ 280H, 282H, 284H and 286H Internal Register Mapping on

page 16.

Examples of frame rate versus resolution:

5.2 Analog Gain

The analog gain can be adjusted by setting the gain register via the serial communication.

• Gain adjusted from 0 dB to 18 dB: code 0 to 6

• Step 3 dB

• Nominal gain (factory configuration): 0 dB

See register Sensor Analog Gain @ 240H, Internal Register Mapping on page 16.
