    摘要: One disclosed embodiment includes detecting flicker in a photographic setting. A plurality of samples are obtained from a light detector circuit of a camera, each of which has a value that is dependent upon intensity of light incident upon the camera. The method further includes processing the samples to identify whether the incident light is varying in intensity at one or more pre-selected frequencies. The processing may include multiplying the samples with one or more periodic signals to generate scalar product outputs, and analyzing the scalar product outputs to ascertain the presence of periodic flicker.

    摘要: A method for suppressing banding and rolling flicker in video acquired by a video camera. The method comprises acquiring a plurality of video frames and assessing an amount of rolling flicker in the plurality of video frames. The method further comprises configuring the video camera to quiet banding and rolling flicker responsive to periodic illumination at a first frequency if the amount of rolling flicker is above a threshold, and, configuring the video camera to quiet banding and rolling flicker responsive to periodic illumination at a second frequency if the amount of rolling flicker is below the threshold.

    摘要: An embodiment of the invention relates to a power converter including a resistor divider with an internal node to sense an input line voltage. The internal node is operable as a multifunctional pin. A controller compares a feedback voltage dependent on a power converter output characteristic to a current-sense signal including an offset dependent on a voltage of the internal node to control entry and exit of the power converter from burst mode operation. The node may be employed to manage power converter operation by sensing or controlling its voltage to signal operation in a standby or burst mode, to sense the input line voltage, to enable an external system to signal shutdown to the power converter, and to enable the power converter to signal a delayed restart condition to the external system.

    摘要: A modulation domain trigger generator demodulates a modulated input signal to extract information content, and a trigger is generated from the extracted information content in response to specified trigger criteria. The modulation domain trigger generator may be combined with a plurality of different types of trigger generators, including frequency domain and time domain trigger generators, to process the input signal in response to different trigger criteria to produce more than one trigger. The different trigger outputs may be combined to produce an acquisition trigger to acquire data surrounding an anomalous or identifiable event within the input signal.
