摘要： An image sensor device is provided that has an uncovered imaging array of pixels and a covered global reference non-imaging array of pixels. The pixel samples of the global reference non-imaging array are used to remove noise from the pixel samples of the imaging array. The control signals and control lines that are used to sample the pixels of the imaging array are separate from and independent of the control signals and control lines that are used to sample the pixels of the global reference non-imaging array of pixels. For each row of pixels of the imaging array that is sampled, the same row of pixels of the global reference non-imaging array is sampled. The global reference row has no or very few offsets or variations to ensure that noise removal is performed effectively.

摘要： A method for compensating for dark current in an image sensor array. In a representative embodiments, the method includes determining a nominal average dark current for the image sensor array, determining location of each pixel in the image sensor array, obtaining a nominal dark current associated with each pixel based on the nominal average dark current and on the location of the pixel, and subtracting the associated nominal dark current from the image signal for each pixel. At least two of the pixels have differing associated nominal dark currents. In other representative embodiments compensation values for dark currents and for differences in channel processing are determined during the same time period.

摘要： A system and method for generating dynamically modifiable timing control signals. Timing waveforms can be changed, for each phase of control, by changing the contents of memory locations and start/stop indices. Parallel signals are generated from the output of the memory locations. The memory locations are accessed in a user-selected order by an index value. This technique of generating timing waveforms, and thus control signals, can be applied to, for example, pixel array development.

摘要： An imaging system implements digital correlated double sampling (CDS) using dual channels. One channel converts reset voltages from pixel sensors to digital reset values, while the other channel converts integrated voltages from pixel sensors to digital integrated values. Timing of an imaging process with digital CDS can accordingly be the same as the timing for an imaging process without digital CDS, regardless of the length of the exposure time. Accordingly, the imaging time and the frame rate for moving images do not suffer when digital CDS is used to improve image quality.
摘要翻译：成像系统使用双通道实现数字相关双采样（CDS）。一个通道将像素传感器的复位电压转换为数字复位值，而另一个通道将集成电压从像素传感器转换为数字积分值。与数字CDS相比，成像过程的时序可以与无数字CDS的成像过程的时序相同，而不考虑曝光时间的长短。因此，当使用数字CDS来提高图像质量时，运动图像的成像时间和帧速率不受影响。
