Abstract:
A light source driver includes a controller which outputs an undershoot current in synchronization with lighting complete timing in lighting information, wherein the controller is configured to output the undershoot current such that a voltage in a light source when the output of the undershoot current is complete is equal to a voltage in the light source before being turned on.
