Publication number: 20240098278Abstract: According to an embodiment, an encoding device includes an index setting unit and an encoding unit. The index setting unit generates a common index in which reference indices of one or more reference images included in a first index and a second index are sorted in a combination so as not to include a same reference image in accordance with a predetermined scanning order. The first index representing a combination of the one or more reference images referred to by a first reference image. The second index representing a combination of the one or more reference images referred to by a second reference image. The encoding unit encodes the common index.Type: ApplicationFiled: November 21, 2023Publication date: March 21, 2024Applicant: KABUSHIKI KAISHA TOSHIBAInventors: Akiyuki TANIZAWA, Takeshi CHUJOH, Taichiro SHIODERA
