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: An embodiment optical device includes a glass plate, a first trench disposed in the glass plate, and a second trench disposed in the glass plate. The second trench crosses the first trench, and the first trench has an open end in a first wall of the second trench. The optical device includes a waveguide disposed inside the first trench, where the waveguide is formed of a material having a refractive index different from that of the glass plate, and a mirror on a second wall of the second trench opposite the first wall and waveguide. The optical device includes an encapsulation layer filling the second trench and covering all of an upper surface of the waveguide and having a refractive index that is different from the waveguide and the glass plate.
