    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.

    Abstract: Embodiments provide a device that includes a first circuit having a first input to receive a first sine wave signal and a second input to receive a second sine wave signal in quadrature with respect to each other and a current mode logic gate having a first input coupled to a first output of the first circuit and a second input coupled to a second output of the first circuit. The first circuit configured to deliver a first square wave signal and a second square wave signal. The current mode logic gate is configured to deliver a third square wave signal at a first level and a fourth square wave signal at a second level when the first and second square wave signals are simultaneously at their first levels and the first square wave signal is ahead of the second square wave signal.
