Output Video and Camera Control Characteristics

Maximum resolutions of output window: 1280 x 1024, full resolution mode
640 x 512, decimated by 2 mode

Frame rate at resolution (24 MHz)*: 15 fps at 1280 x 1024
24 fps at 1024 x 768
37 fps at 800 x 600
40 fps at 768 x 576
54.7 fps at 640 x 480
89.5 fps at 400 x 400
166 fps at 320 x 240

Output bits per pixel: Selectable, 8 bits or 10 bits

Lookup table: Software, converts 10 bits of imaging chip's ADC to 8 bits of output for user selected 8 bits mode

Pixel rates: 12 MHz, 24 MHz

Exposure range
(at maximum resolution), ms:
min: 0.06 (at 24 MHz)
max: more than 2 sec (with fps decrease)

Pixel gain control: Programmable hardware gain: 48 gain levels from 1 to 15
From 1 to 4 with increment 0.125;
from 4.25 to 8 with increment 0.25;
from 9 to 15 with increment 1

Output window modes: View port (from 1280 x 1024 to 8 x 8 with 2 pixels/2 lines step positioning)
Frame Decimation (1:1, 1:2, 1:4, 1:8)
Horizontal "mirroring", hardware
Vertical "flipping", hardware

Gamma, brightness and contrast control: Programmable with lookup table

* Listed frame rate values at the defined resolutions are not the maximal possible. Increasing of frame rate can be done by reducing the current Exposure value (the lower Exposure the higher frame rate is), hiding the active video window, running the camera on a faster computer, etc.
