摘要： A system and method for averaging incident light on plural pixels using a CMOS sensor is provided. The process includes resetting all pixels in a given region during a reset phase; and reading a voltage of a floating reset node as a function of time during a measurement phase. During the reset phase, an access select signal and a reset voltage are both high. The measurement phase begins when the access select signal is low and the reset voltage is still high. The system and method may be used to perform automatic exposure control and automatic white balancing operations.

摘要： A method and apparatus for limiting the absolute magnitude of an audio signal. The method may include firstly variable-gain reducing the gain of an audio signal, and then secondly variable-gain reducing the gain of the audio signal faster than the first variable-gain reduction, thereby limiting the absolute magnitude of the audio signal to a threshold. The first variable-gain reduction may include variable-gain reducing the gain of the audio signal in a first stage, and the second variable-gain reduction may include variable-gain reducing the gain of the audio signal in a second stage that reduces the gain faster than the first stage. The second variable-gain reduction may include delaying the audio signal, finding a peak among the delayed audio signal, calculating a fast gain from a found peak, and modifying the delayed audio signal with the calculated fast gain.
