摘要： A method of increasing dynamic range of pixels in an imaging sensor is disclosed. In one aspect, two image captures are performed, one at a first short integration time and one at a second optimum integration time. An electrical value obtained from a pixel or group of pixels at the first short integration time is used to predict the second integration time using a comparison with a set of reference values. The reference values relate to a saturation electrical value for each pixel or group of pixels to predict the second integration time. The first short integration time is determined as a fractional multiple of the saturation electrical value. The second integration times are such that there is no saturation of the pixel or group of pixels. Adjustments can be made to the reference values to allow for offset immunity and variability in light levels during the second integration time.
摘要翻译： 公开了增加成像传感器中像素的动态范围的方法。 在一个方面，执行两个图像捕获，一个在第一短积分时间，一个在第二最佳积分时间。 使用在第一短积分时间从像素或像素组获得的电值，以使用与一组参考值进行比较来预测第二积分时间。 参考值涉及每个像素或一组像素的饱和电值以预测第二积分时间。 第一个短积分时间被确定为饱和电值的分数倍。 第二积分时间使得像素或像素组没有饱和。 可以对参考值进行调整，以允许在第二积分时间期间的光水平的偏移抗扰度和变化性。

摘要： A self-oscillating driver circuit includes a driver stage, a feedforward path which is coupled to an input of the driver stage, and a feedback path which couples an output of the driver stage to an input of the feedforward path. The feedforward path includes a feedforward filter which is designed as an active filter. In order to prevent an oscillatory state of the driver circuit at an unwanted frequency, it is proposed that an internal state variable of the feedforward filter be monitored and that the feedforward filter be reset if the value of the monitored internal state variable is outside a predefined range.
