Publication number: 20240187646Abstract: The amount of memory required for CCLM prediction is reduced. The CCLM prediction parameter derivation unit (310442) derives a scale shift value corresponding to a luma difference value, and derives a CCLM prediction parameter, by shifting, by using the scale shift value, a value obtained by multiplying a value of a table referred to with a value obtained by performing right shift of the luma difference value by the scale shift value as an index and a chroma difference value. In addition, in a case of deriving a prediction image, a bit width is reduced by adaptively deriving a shift amount of a linear prediction parameter from the chroma difference value.Type: ApplicationFiled: February 9, 2024Publication date: June 6, 2024Inventors: Yukinobu YASUGI, Eiichi SASAKI, Tomohiro IKAI, Tomoko AONO

Patent number: 12003775Abstract: In a scheme in which only a part of one picture is intra-predicted and the rest of the region is inter-predicted, generation of a significant code amount and generation of a delay can be avoided in a specific picture. However, because only a part of the picture is coded by means of the intra prediction, coding efficiency is deteriorated as compared to an I picture in which the entire picture is coded by means of the intra prediction. A picture is split into a restricted region and a non-restricted region. Prediction is performed by using an intra prediction in which only a pixel of the restricted region is referred to or an inter prediction in which a restricted reference region of a reference picture is referred to for a block of the restricted region. Prediction is performed by using the intra prediction in which a decoded pixel in the picture is referred to or the inter prediction in which the reference picture is referred to for the block of the non-restricted region.Type: GrantFiled: August 6, 2019Date of Patent: June 4, 2024Assignee: SHARP KABUSHIKI KAISHAInventors: Eiichi Sasaki, Yukinobu Yasugi, Takeshi Chujoh, Tomoko Aono, Tomohiro Ikai

Publication number: 20240114155Abstract: A method for signaling gradual refresh for encoding a set of pictures performed by an electronic device is provided. The method identifies a first picture in the set of pictures as being associated with a gradual refreshed picture, and stores a network abstraction layer (NAL) unit type in a coded stream associated with the first picture. The NAL unit type identifies a presence of the gradual refreshed picture. The method then stores, in the coded stream, an enable flag to identify a use of the gradual refresh for encoding at least a subset of pictures in the set of pictures.Type: ApplicationFiled: December 7, 2023Publication date: April 4, 2024Inventors: TAKESHI CHUJOH, Yukinobu Yasugi, Eiichi Sasaki, Tomoko Aono, Tomohiro Ikai
