Claim 0:
1. A method of determining motion information predictor candidates for a motion information predictor for encoding an image portion in an image to be encoded by inter prediction, the method comprising for the image portion to be encoded:
acquiring one or more spatial motion information predictor candidates from one or more image portions in the image to be encoded and one or more temporal motion information predictor candidates from one or more image portions in an image different from the image to be encoded;
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 encoded, 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 encoded, 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 encoded is available, the one or more spatial motion information predictor candidates are able to include the motion information of the left image portion.
