    • A digital camera may include a flash unit configured to emit light to illuminate a subject using a preliminary light emission operation followed by a main light emission operation, an image sensor having a pixel array arranged along a plurality of lines, and a digital signal processor. The image sensor may be configured to convert an image of the subject into an electrical signal by reading an image frame corresponding to one screen using the pixel array during the preliminary light emission operation and reading another image frame corresponding to one screen during the main light emission operation. The digital signal processor may be configured to control the light emitting operation of the flash unit to maintain the preliminary light emission from a start to an end of the reading of one image frame.
    • 数字照相机可以包括闪光单元,其被配置为发射光以使用主发光操作之后的初步发光操作,具有沿着多条线布置的像素阵列的图像传感器和数字信号处理器来发光。 图像传感器可以被配置为通过在初步发光操作期间使用像素阵列读取与一个屏幕相对应的图像帧来将被摄体的图像转换为电信号,并且在主发光期间读取与一个屏幕相对应的另一图像帧 操作。 数字信号处理器可以被配置为控制闪光单元的发光操作以保持从一个图像帧的读取的开始到结束的初步光发射。

    • Provided are a lens-interchangeable digital photographing apparatus that can use a suitable lens according to a photographing circumstance, a method of controlling the lens-interchangeable digital photographing apparatus, and a recording medium having recorded therein a program for the method. The lens-interchangeable digital photographing apparatus includes a photographing circumstance analysis unit, a lens suitability determination unit for determining whether a lens installed in the digital photographing apparatus is suitable for a photographing circumstance, a lens search unit for searching for lenses suitable for a photographing circumstance, and a display unit. If the lens suitability determination unit determines that the installed lens is not suitable for the photographing circumstance, lenses suitable for the photographing circumstance analyzed by the photographing circumstance analysis unit from among lenses searched by the lens search unit are displayed on the display unit to be recommended.

    • A spool-out type booster brake valve device for industrial vehicles is configured to allow hydraulic working fluid to be supplied not only to a booster chamber but also to a master chamber thereby eliminating the need to use a separate brake fluid reservoir tank for supplementing brake fluid in the master chamber. The brake valve device is used in an industrial vehicle equipped with a fluid pump, a reservoir tank and a brake actuator. The brake valve device includes a valve body having an inlet port, a drain port, a brake port, a booster chamber communicatable with the pump via the inlet port and a master chamber communicatable with the brake actuator via the brake port. The master chamber is connected to the inlet port to receive working fluid from the pump. A valve spool is slidably fitted in the valve body through the booster chamber and the master chamber, the valve spool being shifted between an idle position and an operating position. The brake valve device also includes a booster sleeve and a master piston which are moved along with the valve spool in response to the shifting movement of the valve spool into the operating position, thereby reducing the volume of the master chamber so that the fluid in the master chamber can be introduced into the brake actuator via the brake port.
    • 用于工业车辆的排液式增压制动阀装置构造成允许液压工作流体不仅被供给到增压室,而且还供给主室,从而不需要使用单独的制动液储罐来补充制动液 在主室。 制动阀装置用于配备有流体泵,储存罐和制动致动器的工业车辆中。 制动阀装置包括具有入口端口,排水口,制动口,通过入口与泵连通的增压室的阀体以及通过制动端口与制动器致动器通信的主室。 主室连接到入口以从泵接收工作流体。 阀芯通过增压室和主室可滑动地装配在阀体中,阀芯在空转位置和操作位置之间移动。 制动阀装置还包括增压套管和主活塞,其响应于阀芯进入操作位置的移动运动而与阀芯一起移动,从而减小主室的体积,使得流体在 主室可以通过制动口引入制动执行器。
