Abstract
A detection device comprises an array of pixels, each pixel including a sensor and generating an oscillating signal (S); and a frequency detection circuit () for detecting the frequency of the oscillating output signal of one or more of the pixels, the frequency detection circuit having: a window generation circuit () adapted to generate at least one output signal (WIN_SEN) indicating the start and end times of a first time duration (TWINDOW) corresponding to a plurality of periods of the oscillating output signal; and one or more counters () adapted to receive at least one reference signal (TCOUNT, TREAD) indicating the start and end times of a reference time duration (TREF), and to quantify a difference between the first time duration and the reference time duration.
