Title:
LIQUID LENS CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/006592
Kind Code:
A1
Abstract:
A liquid lens control device according to one embodiment comprises: a liquid lens in which a liquid interface is controlled in response to a plurality of individual voltages applied to each of a plurality of individual electrodes; a control unit for controlling the plurality of individual voltages; and a compensation unit for compensating for characteristics of at least one individual electrode from among the plurality of individual electrodes. The characteristic compensated for by the compensation unit can be the position of the interface according to the individual voltage applied to the individual element. The compensation unit can perform the compensation by using a first ADC value acquired when a first voltage is applied to each of the plurality of individual electrodes, and a second ADC value acquired when a second voltage that differs from the first voltage is applied to each of the plurality of individual electrodes.
