Abstract: In an embodiment method for detecting the phase of an analog signal via a hybrid coupler operating in a power-combiner mode, the hybrid coupler comprises a first input intended to receive the analog signal, a second input intended to receive a reference signal having a reference phase and the same frequency as the analog signal, and two outputs, and is configured to generate, at these two outputs, a first output signal and a second output signal, respectively. The embodiment method comprises measuring peak values of the analog signal, of the reference signal, and of at least one of the first and second output signals, calculating the phase shift between the phase of the analog signal and the reference phase depending on the measured peak values, and determining the phase of the analog signal depending on the calculated phase shift and the reference phase.

Abstract: A processing system includes a communication system and a processing core configured to generate write requests. A circuit has associated a slave interface circuit configured to manage an address sub-range and selectively forward write requests addressed to a given address. Configuration data specifies whether the given address is protected/unprotected and locked/unlocked. In response to a received write request, address and data are extracted and a determination based on the configuration data is made as to whether the extracted address is protected/unprotected, and locked/unlocked. When the extracted address is unprotected or unlocked, the slave interface forwards the write request. When the extracted address is protected and locked, the slave interface generates an unlock signal in response to a comparison of the extracted address with the extracted data, with the unlock signal being asserted when the extracted data satisfy a predetermined rule with respect to the extracted address.

Abstract: A cell includes a Z2-FET-type structure that is formed with two front gates extending over an intermediate region between an anode region and a cathode region. The individual front gates of the two front gates are spaced apart by a distance that is shorter than 40% of a width of each individual front gate.

Abstract: A method includes estimating first distance values associated with a plurality of first pixels, based on light pulses of a first light pulse train having a first period, estimating second distance values associated with a plurality of second pixels, the second distance values being estimated for each second pixel based on a second light pulse train having a second period different from the first period, for each of the first pixels being adjacent to one of the second pixels, validating or invalidating the first distance values, based on a comparison between the estimations of the first distance value and at least one of the second distance values of at least one second adjacent pixel, and storing an indication of the first pixels having been validated and/or invalidated.

Abstract: The method of determination of a depth map of a scene comprises generation of a distance map of the scene obtained by time of flight measurements, acquisition of two images of the scene from two different viewpoints, and stereoscopic processing of the two images taking into account the distance map. The generation of the distance map includes generation of distance histograms acquisition zone by acquisition zone of the scene, and the stereoscopic processing includes, for each region of the depth map corresponding to an acquisition zone, elementary processing taking into account the corresponding histogram.

Abstract: The method for processing a matrix of pixels each containing an original red, green, blue, or infrared component, comprises at least one interpolation of an interpolated component different from the original component of a pixel of interest from the components of a group of pixels neighboring the pixel of interest. The interpolation comprises: a calculation of the sum of the components of reference pixels weighted by a respectively assigned weight, the reference pixels being pixels of the group having the same original component as the interpolated component, an evaluation of the spatial uniformity of an environment, within the group of each reference pixel, a calculation of the weights assigned to the reference pixels at values which are normalized and proportional to the respective spatial uniformity.

Abstract: An embodiment method for estimating a missing or incorrect value in a table of values generated by a photosite matrix comprises a definition of a zone of the table comprising the value to be estimated and other values, referred to as neighboring values, and an estimation of the value to be estimated based on the primary neighboring values and the weight associated with these primary neighboring values, wherein a weight of each neighboring value, referred to as primary neighboring value, of the same colorimetric component as that of the missing or incorrect value to be estimated, is determined according to differences between neighboring values disposed on an axis and neighboring values disposed parallel with this axis and positioned in relation to this axis on the same side as the primary neighboring value for which the weight is determined.
