A method for processing a stereoscopic image that includes a first image and a second image that has at least one first black band. To reduce the display errors linked to black bands, the method estimating at least one first parameter representative of the at least one first black band generating a third image from the stereoscopic image by disparity compensated interpolation. The third image includes at least one second black band, with at least one second parameter representative of the at least one black band being a function of at least one first parameter. The invention also relates to a corresponding stereoscopic image processing module and a display device including the processing module.
