    • Provided is a technique capable of correcting not only a variation due to a moving speed and a temperature change of a lens but also a variation due to a focal distance and a temperature change of the lens, with a high degree of accuracy.An optical device (100) includes a control unit (1), a lens (2), an image sensor (3), a temperature sensor (4), a storage unit (5) that stores a driving pulse number, lens information, and speed information of the lens (2), an image signal processing unit (6) that acquires the lens information and the speed information from the storage unit (5) under the control of the control unit (1), a piezoelectric element (7) that moves the lens (2), and a driver (8) that controls the piezoelectric element (7). The image signal processing unit (6) moves the lens (2) by the piezoelectric element (7), using the lens information and temperatures of the lens (2) and the piezoelectric element (7), and controls the piezoelectric element (7), using the speed information and the temperature of the piezoelectric element (7).
    • 提供了一种能够以高精度校正不仅由于移动速度和透镜的温度变化引起的变化而且由于焦距和透镜的温度变化引起的变化的技术。 光学装置(100)包括控制单元(1),透镜(2),图像传感器(3),温度传感器(4),存储驱动脉冲数的存储单元(5) 以及透镜(2)的速度信息,在控制单元(1)的控制下从存储单元(5)获取透镜信息和速度信息的图像信号处理单元(6),压电元件(7) )和用于控制压电元件(7)的驱动器(8)。 图像信号处理单元(6)使用透镜信息和透镜(2)和压电元件(7)的温度,使透镜(2)移动通过压电元件(7),并且控制压电元件(7) ,使用压电元件(7)的速度信息和温度。
