摘要： The reduced signal-to-noise ratio of colored pixels that results from a lower conversion efficiency is eliminated by utilizing a programmable gain amplifier which individually applies a gain to the output of each colored pixel so that the maximum signal level of each colored pixel is matched to the maximum input range of an A/D converter.

摘要： The present invention provides a method and apparatus for calibrating a black level in an imager to reduce flicker noise. A first and a second range is set. The first range corresponds to a range that is larger than a noise level at a highest PGA gain. The second range corresponds to a range that is smaller than a level which reduces an ADC dynamic range too much due to a large black level. The ranges may be adjusted to changes in an imager in real time. When the black level is within the second range a determination is made as to whether the black level has been calibrated before. When it has, the DAC output is held constant. Otherwise the DAC code is adjusted such that the black level is moved toward the first range. A small step size is used in adjusting the DAC code in order to reduce flicker. Step sizes may be adjusted according to the black level in relation to the ranges. A small step size is used when the black level is within the second range. A large step size is used when the black level is beyond the second range.
摘要翻译：本发明提供了一种用于在成像器中校准黑电平以减少闪烁噪声的方法和装置。设置第一和第二范围。第一范围对应于在最高PGA增益下大于噪声电平的范围。第二范围对应于小于由于大的黑电平而使ADC动态范围过大的电平的范围。范围可以实时调整成像仪的变化。当黑色电平处于第二范围内时，确定黑电平是否已被校准。当它有，DAC输出保持不变。否则调整DAC代码，使得黑色电平移动到第一范围。为了减少闪烁，使用小步长调整DAC代码。可以根据与范围相关的黑色级别调整步长。当黑色电平在第二范围内时，使用小步长。当黑色电平超出第二范围时，使用较大的步长。

摘要： A linear pixel-array processing systems uses a combination of digital and analog signal processing techniques to calibrate the gain and offset of each pixel in the analog domain. A plurality of fixed gain and offset values are applied in the analog domain to adjust the gain and offset of each pixel at high speeds (on the order of 25–50 MHz). By adjusting the gain and offset in the analog domain, the dynamic range of pixel conversion is improved such that the conversion range is fully utilized (over 90%, on the order of 95%–99%). The gain and offset values are determined with an algorithmic calibration routine that corrects for non-ideal effects in the signal path. A single processing channel can be multiplexed to process multiple pixel arrays to provide for a cost effective solution. In higher speed systems, the single processing channel can be extended to multiple processing channels for improved throughput.
摘要翻译：线性像素阵列处理系统使用数字和模拟信号处理技术的组合来校准模拟域中每个像素的增益和偏移。在模拟域中应用多个固定的增益和偏移值，以便在高速（大约25-50 MHz）上调整每个像素的增益和偏移。通过调整模拟域中的增益和偏移量，可以提高像素转换的动态范围，使得转换范围得到充分利用（超过90％，大约为95％-99％）。增益和偏移值通过校正信号路径中非理想效应的算法校准程序来确定。单个处理通道可以被多路复用以处理多个像素阵列以提供成本有效的解决方案。在高速系统中，单处理通道可以扩展到多个处理通道，以提高吞吐量。
