6 ROLLING SHUTTER
Exposure time < Sensor frame readout time
In case the required exposure time is shorter than the frame readout
time, the image is readout through an exposure band moving from
the top to the bottom of the sensor.
For example:
How can you calculate the band of simultaneous exposure lines at an
exposure time of 100μs (@ full resolution)?
Exposure time
Line time
= Number of simultaneous exposure lines
100 µs
12.174 µ𝑠𝑠
= 8,2 → 8 lines
