  • JITTER MEASUREMENT CIRCUIT AND JITTER MEASUREMENT METHOD
    Publication number: 20250123327
    Abstract: A jitter measurement circuit for measuring a jitter of an input signal, the jitter measurement circuit including: a multiplexer configured to output a first comparison signal or a second comparison signal in response to an output signal; a detecting circuit configured to output a detection signal corresponding to a phase difference between an output of the multiplexer and the input signal; a first adder configured to sum the detection signal and a feedback signal; an integrating circuit configured to integrate and output an output of the first adder; a feedback circuit configured to trim an output of the integrating circuit to generate the feedback signal; and a comparator configured to generate an output signal by comparing the output of the integrating circuit with a reference potential.

  • Method of detecting pedestrians using integral image of feature information, computer readable recording medium, and terminal device for the same
    Patent number: 9430708
    Abstract: Provided is a method of detecting a pedestrian through feature information prediction based on an integral image. The method includes extracting a feature image of an obtained original image; generating an integral image of the feature image; predicting an integral image of an enlarged/reduced feature image using the integral image of the feature image and an image enlargement/reduction scale value; and detecting a pedestrian using an integral image of the predicted enlarged/reduced feature image. Accordingly, it is possible to decrease a time taken for a feature extracting operation, and perform pedestrian detection efficiently.
