Patent number: 9781404Abstract: The present disclosure relates to a method for transmitting two consecutive pairs of images. The method may include decimating each image with a ratio of 2, assembling the two decimated images of each pair in a composite image, transmitting the composite images, and reconstructing complete images from the composite images. In decimation, the information removed from the images of the first pair may be kept in the images of the second pair, from the spatial point of view, and the complete images may be reconstructed by de-interlacing processing from the composite images.Type: GrantFiled: November 30, 2015Date of Patent: October 3, 2017Assignee: STMICROELECTRONICS (GRENOBLE 2) SASInventors: Frankie Eymard, Jean-Louis Labyre
