Publication number: 20240135155Abstract: In a data processing device, a fixed-point position control unit determines, as first control. The fixed-point position control unit causes a detection calculation unit to perform calculation processing on processing target data at a processing point in time. The saturation rate control unit instructs, as second control to be repeated by the fixed-point position control unit, the fixed-point position control unit to move at least the fixed-point position as control to increase a lower limit saturation rate proportional to a magnitude of a counted lower limit counter value with respect to a result of the first control. The fixed-point position control unit performs, as the second control, a predetermined determination on the basis of the instruction from the saturation rate control unit and the metadata, determines the fixed-point position moved for each layer, and causes calculation processing to be performed.Type: ApplicationFiled: December 28, 2020Publication date: April 25, 2024Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Saki HATTA, Hiroyuki UZAWA, Shuhei YOSHIDA, Daisuke KOBAYASHI, Yuya OMORI, Ken NAKAMURA, Koyo NITTA

Publication number: 20240119605Abstract: A calculation unit (22) sets each frame, of a moving image including a plurality of frames, as a target frame, calculates a motion vector with reference to a reference frame over an entirety of the target frames, and calculates an index indicating a magnitude of change between a key frame and the target frame, which is represented by using the motion vector, a judgement unit (25) judges whether or not the calculated index is equal to or greater than a predetermined threshold value, a first detection unit (27) detects a region indicating an object from the target frame by using an object detection model in a case in which the index is equal to greater than the threshold value, a second detection unit (28) detects a region on the target frame, which is obtained by correcting a position of a region detected in the reference frame by using the motion vector in a case in which the index is less than the threshold value, and an output unit (30) outputs information of the region detected by the first detection unitType: ApplicationFiled: February 9, 2021Publication date: April 11, 2024Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Ken NAKAMURA, Hiroyuki UZAWA, Daisuke KOBAYASHI, Saki HATTA, Yuya OMORI, Shuhei YOSHIDA

Patent number: 10240136Abstract: To provide an improved ?-fructofuranosidase which is capable of efficiently producing kestose while inhibiting the production of nystose. This improved ?-fructofuranosidase comprises either: an amino acid sequence (a) obtained by introducing, into the amino acid sequence represented by SEQ ID NO: 2, an amino acid mutation i) in which the 85th glycine (G) from the N-terminal is substituted for a protein-constituting amino acid other than glycine (G), and/or an amino acid mutation ii) in which the 310th histidine (H) from the N-terminal is substituted for lysine (K), arginine (R), or tyrosine (Y); or an amino acid sequence (b) which exhibits ?-fructofuranosidase activity, and which comprises an amino acid sequence obtained by deleting, substituting, inserting, or adding one or more amino acids in (a) other than the amino acid into which the amino acid mutation has been introduced.Type: GrantFiled: March 10, 2016Date of Patent: March 26, 2019Assignees: B FOOD SCIENCE CO., LTD., MICROBIOPHARM JAPAN CO., LTD.Inventors: Takumi Tochio, Naomi Ito, Saki Nakamura, Yoshimi Fukatani, Tadashi Fujii, Keisuke Tamura
