    • An embodiment of the invention provides a camera comprising a photosurface that is electronically turned on and off to respectively initiate and terminate an exposure period of the camera at a frequency sufficiently high so that the camera can be used to determine distances to a scene that it images without use of an external fast shutter. In an embodiment, the photosurface comprises pixels formed on a substrate and the photosurface is turned on and turned off by controlling voltage to the substrate. In an embodiment, the substrate pixels comprise light sensitive pixels, also referred to as “photopixels”, in which light incident on the photosurface generates photocharge, and storage pixels that are insensitive to light that generates photocharge in the photopixels. In an embodiment, the photosurface is controlled so that the storage pixels accumulate and store photocharge substantially upon its generation during an exposure period of the photosurface.
    • 本发明的一个实施例提供了一种照相机,其包括电子地打开和关闭以分别以足够高的频率启动和终止照相机的曝光周期的光敏面,使得照相机可以用于确定到其图像的场景的距离 不使用外部快门。 在一个实施例中,光敏表面包括形成在衬底上的像素,并且通过控制对衬底的电压将光敏面接通和关断。 在一个实施例中,衬底像素包括也被称为“照相像素”的光敏像素,其中入射在光电面上的光产生光电荷,以及对在光像元件中产生光电荷的光不敏感的存储像素。 在一个实施例中,控制光敏表面,使得存储像素在照射面的曝光期间基本上累积并存储光电荷。
