Image Sensor and colour modes
The 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
