Abstract
A driving device is provided. The driving device includes a signal processing circuit and a driving circuit. The signal processing circuit is configured to generate a current input signal according to a target current signal. The driving circuit is configured to receive the current input signal and generate a current output signal according to the current input signal to drive a light emitting element. In a first time interval, the current input signal gradually rises from a first current value to a target current value in a continuous or segmented manner according to a rising slope. Further, a control method of the driving device and a lighting system including the driving device are also provided.
