Image Sensor

The Uniiqa+ sensor is composed of two sensitive lines of 4096 pixels of 5µm square : One composed of
Green pixels only, the second one composed alternatively of Red/Blue Pixels.
Each pixel on the same column uses its own Analog to Digital Column converter (ADC Column).
This structure allows several definitions :

4k pixels 5x5µm (Full Definition) :

The 2 color lines are exposed with a delay of
one line in order to match the same position
between the green line and the red/blue line

2k Pixels 10x10µm (True Color) :

The colored pixel is composed of 2x Green
pixels, one red and one blue exposed in the
same time.

Then, 1k or 0,5k 10x10µm are achieved by
applying an ROI on the centre of the sensor
from the 2k 10x10µm

This color mode (5µm) requires the indication of "Forward/Reverse" to the camera in order to manage the
delay between the two colored lines.

These color modes don't require any Reverse/Forward indication if no interpolation is used (or only the
"column interpolation")
