Title:
IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/098568
Kind Code:
A1
Abstract:
In this imaging device, a driving control unit outputs a voltage command value V* that changes in stages at a time interval (ΔT) shorter than the response time of a liquid lens with respect to a driving unit that drives the liquid lens in accordance with the voltage command value V*. The driving control unit may change the voltage command value V* output to the driving unit in stages up until a target command value Vg. When changing the voltage command value V* in stages, the driving control unit may change the voltage command value V* in such a manner that the amount of change in the voltage command value V* in each stage (initial amount of change ΔVini, amount of change ΔV) is a prescribed ratio with respect to the total value (target amount of change ∆Vg) of the amount the voltage command value V* changed in each stage up until the target command value Vg.
