Method of processing 3D images, and corresponding system including the formulation of missing pixels using windows of details from first and second views

A system for processing a multiplex image, the multiplex image comprising at least one first view intended to be viewed by a first eye of an observer and at least one second view intended to be viewed by a second eye of the observer, the two views being spatially sub-sampled according to complementary grids and mutually spatially shifted, the system comprising:

• an input block configured to receive the multiplex image;
• and
• a processing block comprising
• a demultiplexing block configured to demultiplex the multiplex image to extract the first view to be observed by the first eye of the observer and the second view to be viewed by the second eye of the observer,
• a first determination block configured to determine a first window of the first view containing the location of a missing pixel of the first view and representing a first detail in the first view, the missing pixel being the result of sub-sampling during multiplexing of the multiplex image,
• a second determination block configured to determine a second window of the second view representing the first detail, of the first window of the first view, in the second view, wherein the second window is shifted by a shift value corresponding to a local parallax between the two views associated with the detail,
• a formulation block configured to formulate the missing pixel of the first view by using the pixels of the second window of the second view, to determine a value for the missing pixel of the first window, wherein the value is inserted into the first window, and
• a control block configured to activate the first and second determination blocks and the formulation block.

An electronic device comprising:
