Claim 3:
4. A method of determining motion information predictor candidates for a motion information predictor for decoding of an image portion in an image to be decoded by inter prediction, the method comprising for the image portion to be decoded:
acquiring one or more spatial motion information predictor candidates from one or more image portions in the image to be decoded and one or more temporal motion information predictor candidates from one or more image portions in an image different from the image to be decoded;
performing first processing on motion information predictor candidates including the one or more spatial motion information predictor candidates but not including any temporal motion information predictor candidates for the image portion to be decoded, wherein the first processing comprises excluding a duplicate spatial motion information predictor candidate;
performing second processing on motion information predictor candidates for the image portion to be decoded, wherein the second processing comprises excluding a duplicate temporal motion information predictor candidate;
obtaining, based on at least one or more spatial motion information predictor candidates and one or more temporal motion information predictor candidates resulting from the first and second processing, a set of motion information predictor candidates for the motion information predictor,
wherein, in a case where motion information of a left image portion of the image portion to be decoded is available, the one or more spatial motion information predictor candidates are able to include the motion information of the left image portion.
