摘要： An apparatus for and a method of operating an array of pixels of an image sensor, where each pixel includes at least a photosensor, an associated storage device and a floating diffusion region and the array of pixels is configured in a plurality of rows and columns. The photosensors associated with the pixels are reset and charges are accumulated in the photosensor. The accumulated charges are then globally transferred to storage devices associated with the pixels. A rolling double reset is used to reduce the deleterious effects on the accumulated charges stored in the storage devices. The accumulated charges stored in the storage devices are transferred to floating diffusion regions associated with the pixels and the charges residing in the floating diffusion region are read out. In a second embodiment the storage device is eliminated and the rolling double reset is used to reduce the deleterious effects on the accumulated charges stored in the floating diffusion region.

摘要翻译：一种用于操作图像传感器的像素阵列的设备和方法，其中每个像素至少包括光电传感器，相关联的存储设备和浮动扩散区域，并且像素阵列被配置成多行和多列。与像素相关联的光电传感器被重置并且电荷在光电传感器中累积。然后将累积的电荷全局转移到与像素相关联的存储设备。滚动双重置用于减少对存储在存储设备中的累积电荷的有害影响。存储在存储装置中的累积电荷被转移到与像素相关联的浮动扩散区域，并且读出驻留在浮动扩散区域中的电荷。在第二实施例中，存储设备被消除并且滚动双重置被用于减少对存储在浮动扩散区域中的累积电荷的有害影响。
