Output Mode

Output Mode:

Normal:

Normal mode.

LFSR:

Test image. Linear feedback shift register (pseudo-random image). The pattern depends

on the grey level resolution.

Ramp:

Test image. Values of pixel are incremented by 1, starting at each row. The pattern

depends on the grey level resolution.

LUT:

Look-Up-Table, a 10-to-8-bit mapping of grey levels.

Resolution:

8 Bit:

Grey level resolution of 8 bit.

10 Bit:

Grey level resolution of 10 bit.

12 Bit:

Grey level resolution of 12 bit.

Digital Gain:

1x:

No digital gain, normal mode.

2x:

Digital gain 2.

4x:

Digital gain 4.
