Patent number: 11165952Abstract: An information processing apparatus includes a control circuit configured to set or transmit a first learning parameter to a determining device that performs processing based on a learning parameter. The control circuit sets or transmits a second learning parameter instead of the first learning parameter to the determining device in a case where a result of a determination made by the determining device satisfies a predetermined condition. The first learning parameter is a learning parameter that is obtained by performing machine learning using a first learning data group. The second learning parameter is a learning parameter that is obtained by performing machine learning using a second learning data group. The first learning data group encompasses the second learning data group and includes learning data that is not included in the second learning data group.Type: GrantFiled: November 22, 2019Date of Patent: November 2, 2021Assignee: Canon Kabushiki KaishaInventor: Junji Tada

Patent number: 9838658Abstract: An image processing apparatus which is capable of properly performing tone correction without damaging the atmosphere of an image in shooting. Based on a luminance histogram for photographed data, an input lower limit and an input upper limit of luminance values for use in developing the photographed data are determined. Based on at least one of the input lower limit and the input upper limit, a reference level of a gamma curve for use in carrying out gamma correction on the photographed data is calculated. Gamma correction on the photographed data is performed using the input lower limit and the input upper limit and the gamma curve corresponding to the reference level.Type: GrantFiled: March 31, 2015Date of Patent: December 5, 2017Assignee: CANON KABUSHIKI KAISHAInventor: Junji Tada

Patent number: 9780694Abstract: Provided is a power converter capable of reliably turning OFF a switching element before turn-OFF of a diode even with a fluctuation in rpm so as not to generate a backflow of a current. The power converter includes a diode ON-interval monitoring unit (18) configured to measure a change rate of a diode ON detection interval signal. When a diode ON detection interval change rate signal (S20) exhibits a decrease on a negative side and is smaller than a predetermined value (an absolute value thereof exceeds a predetermined value), an OFF-timing of the switching element is advanced by a predetermined value or larger, to thereby reliably turn OFF the switching element before the turn-OFF of the diode even with the fluctuation in rpm.Type: GrantFiled: April 7, 2014Date of Patent: October 3, 2017Assignee: Mitsubishi Electric CorporationInventors: Junji Tada, Kenichi Akita, Katsuya Tsujimoto, Keiichi Komurasaki

Patent number: 7974790Abstract: A particulate determination method determines by onetime scanning, the size of a particulate included in a plurality of particulates of various sizes which are arranged on a disc. False recognition of the number of particulates is avoided even when a plurality of particulates are adjacent to each other. A photodetector detection signal is judged using plural threshold values according to the sizes of particulates to be detected. Results of determinations corresponding to the respective threshold values are stored on mutually independent memory maps. When counting particulates, a particulate size and a particulate count value are determined from a combination of stored data appearing in a scanning window at the same position on the respective memory maps.Type: GrantFiled: June 19, 2008Date of Patent: July 5, 2011Assignee: Panasonic CorporationInventors: Junji Tada, Hideyuki Kurokawa, Yoshiyuki Fujii
