I see many CMOS sensors with the pin called trigger. WHat exactly does this pin do ? What is it used for in a camera?
My knowledge about CMOS sensors is not extensive. As far as i know the trigger I thought was used to control the accumulation time on the CMOS sensor. However, I see some articles online that talk about using this trigger pin to sync multiple cameras , something like a global shutter which discharges the CMOS sensor everytime before beginning a new read. My question, is there any way to use this trigger pin http://www.sony.net/Products/SC-HP/sensor/img/product/cmos/IMX249LQJ_LLJ_Flyer.pdf to synchronize the sensors.
TRIGGER
is an input pin and would be used for:Snapshot trigger. Used to trigger one frame of output in snapshot modes, and to indicate the end of exposure in bulb exposure modes
In case of a AR0134CS Sensor,TRIGGER
, also an INPUT pin would be used for:Exposure synchronization input
Each CMOS Sensor has its own specific specs, which seems to not be standard \$\endgroup\$Trigger mode
. Those are 2 totally different things. \$\endgroup\$
