Claim 9:
10. A device for 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 device comprising:
an acquiring unit configured to acquire 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 portion in an image different from the image to be decoded;
a first processing unit configured to perform 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 predetermined processing comprises excluding a duplicate spatial motion information predictor candidate;
a second processing unit configured to perform 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;
an obtaining unit configured to obtain, based on at least one or more spatial motion information predictor candidates and one or more temporal motion information 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.
