    • Disclosed herein is a piezoelectric actuator drive system for forward or backward driving a piezoelectric actuator for zooming and/or focusing in a camera module. The piezoelectric actuator drive system comprises a power supply for supplying an operating voltage, a drive controller for controlling generation of a forward/backward drive signal for a piezoelectric actuator in response to an operation ON select signal and a forward/backward driving select signal, a clock generator for generating a first clock signal in response to the operating voltage from the power supply, and a drive signal generator for generating and supplying the forward or backward drive signal to the piezoelectric actuator in response to the first clock signal from the clock generator and the operating voltage from the power supply under the forward/backward drive signal generation control of the drive controller.

    • A digital photo managing apparatus and method, and a recording medium readable by computer. The digital photo managing apparatus includes: an attribute information generating unit which generates specified attribute information for given photo data; a storage unit which stores the attribute information and the given photo data by having the attribute information as an address; an attribute information inserting unit which inserts the attribute information in the given photo data, and prints the photo data including the attribute information to generate a photo; a reading unit which reads the photo and detects the attribute information; and a photo data searching unit which reads out the stored photo data which has attribute information within a pre-set degree of association with the detected attribute information as an address from the stored photo data. Thus, the specified photo data can be read despite damages to a portion of the digital photo, photo data related to the photo data of the digital photo can be easily searched, and images of the searched photo data can be displayed according to the intensions of the user.
    • 一种数字照片管理装置和方法,以及可由计算机读取的记录介质。 数字照片管理装置包括:属性信息生成单元,生成用于给定照片数据的指定属性信息; 存储单元,其通过使属性信息作为地址来存储属性信息和给定的照片数据; 属性信息插入单元,其将属性信息插入给定的照片数据中,并打印包括属性信息的照片数据以生成照片; 读取单元,读取照片并检测属性信息; 以及照片数据搜索单元,其从存储的照片数据中读出具有与所检测的属性信息相关联的预设度关联的属性信息作为地址的所存储的照片数据。 因此,尽管损害了数字照片的一部分,但是可以读取指定的照片数据,可以容易地搜索与数字照片的照片数据相关的照片数据,并且可以根据图像的意图显示所搜索的照片数据的图像 用户。
