    • A camera system and method for operation of fill flash photography, combining natural and flash light, which centres the times of natural light and flash light images. Synchronization is achieved by centring the time a flash is triggered midway between the opening front curtain and closing rear curtain of the shutter. In a particular preferred embodiment, a digital camera is coupled to a computer forming a system which stores images for image processing. The system includes a means for determining a period during which the shutter of the camera system will be opened and a means to determine a middle period in the the open shutter period. Preferably, the flash is fired at the midway point of the shutter period. This midway point in time is used to trigger the flash so it is substantially centred in time within the shutter period.
    • 一种照相机系统和方法,用于进行补光闪光拍摄,结合自然光和闪光灯,以自然光和闪光灯图像的时间为中心。 通过将闪光灯在打开的前帘和闭合的后帘之间的中间的时间对齐来实现同步。 在特别优选的实施例中,数字照相机耦合到形成用于存储用于图像处理的图像的系统的计算机。 该系统包括用于确定照相机系统的快门将被打开的时间段的装置和用于确定打开的快门时段中的中间周期的装置。 优选地,闪光灯在快门时段的中间点被点燃。 这个中间时间点用于触发闪光灯,使其在快门时段内的时间基本上居中。
