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： 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.

A switched output signal between the controllable paths of the limiting and complementary limiting transistors can be taped off, the controllable paths of the limiting and the complementary limiting transistors are connected together and are connected to a first and a second supply terminal via the controllable paths of the switching and complementary switching transistors, and the switching and the complementary switching transistors have a lower electrical strength than the limiting and complementary limiting transistors. The output stage further comprises a level matching device for generating control signals in response to an input switching signal. The matching device is connected to the supply voltage and the control signals are fed to the control terminals.
