摘要： A system of taking images of different sensitivities at the same time uses both an image sensor, and an auxiliary part to the image sensor. The image sensor element can be a photogate, and the auxiliary part can be the floating diffusion associated with the photogate. Both the photogate and the floating diffusion accumulate charge. Both are sampled at different times. The floating diffusion provides a lower sensitivity amount of charge than the photogate itself. The system can have a photogate and floating diffusion in each pixel along with a select transistor, a reset transistor, and a follower transistor. All of this circuitry can be formed of CMOS for example. The system can also operate in a column/parallel mode, where each column of the photo sensor array can have a column signal processor which samples and holds the reset signal, the floating diffusion signal and the photogate signal.
摘要翻译：同时拍摄不同灵敏度的图像的系统使用图像传感器和图像传感器的辅助部件。图像传感器元件可以是光栅，并且辅助部件可以是与光栅相关联的浮动扩散。光栅和浮动扩散都积聚电荷。两者都在不同时间采样。浮动扩散提供比光栅本身更低的灵敏度的电荷。该系统可以与选择晶体管，复位晶体管和跟随器晶体管一起在每个像素中具有光栅和浮动扩散。例如，所有这种电路可以由CMOS形成。该系统还可以以列/并行模式工作，其中光传感器阵列的每列可以具有采样并保持复位信号，浮动扩散信号和光栅信号的列信号处理器。

摘要： An active pixel sensor (APS) that includes circuitry to eliminate artifacts in digital images. The APS includes a comparator for comparing a signal level from a pixel to an adjusted saturation voltage to determine if the pixel is saturated. If the pixel is saturated, the signal output from the pixel is replaced with an analog voltage having a maximum value corresponding to a brightest pixel in the image.

摘要： A histogram is modified by using an adaptive system. Two different thresholds are set: a threshold of a number of pixels which can be changed, and another threshold indicative of a total number of pixels which can be combined together. The thresholds can be adaptively based on results of frame operations.
