Actual Time Applied for Commands
When you execute a command, the actual or real time applied for the command varies depending on the type of
the command and operating status of the camera.
All commands except Set Exposure Time (
“set”) command are applied to change the settings as illustrated
below, on the rising edge of a VCCD signal before starting readout process.
When you execute a
“set” command, the exposure time setting will be changed at the starting of the exposure.
In the Trigger mode, you must execute commands before applying trigger signals in order to synchronize image
outputs with the commands.
In the Free-Run mode, even if you execute a command, you may acquire up to two images without applying the
command. This is true because it is hard to verify the current operating status of the camera in the Free-Run
mode.
