Patent number: 10490181Abstract: The present invention is provided with: a voice input section that receives a remark (a question) via a voice signal; a reply creation section that creates a voice sequence of a reply (response) to the remark; a pitch analysis section that analyzes the pitch of a first segment (e.g., word ending) of the remark; and a voice generation section (a voice synthesis section, etc.) that generates a reply, in the form of voice, represented by the voice sequence. The voice generation section controls the pitch of the entire reply in such a manner that the pitch of a second segment (e.g., word ending) of the reply assumes a predetermined pitch (e.g., five degrees down) with respect to the pitch of the first segment of the remark. Such arrangements can realize synthesis of replying voice capable of giving a natural feel to the user.Type: GrantFiled: December 12, 2016Date of Patent: November 26, 2019Assignee: YAMAHA CORPORATIONInventors: Hiroaki Matsubara, Junya Ura, Takehiko Kawahara, Yuji Hisaminato, Katsuji Yoshimura

Patent number: 6370330Abstract: An image shake detecting device for detecting a shake of an image on an image sensing plane on the basis of a video signal output from an image sensor includes detection circuits arranged to detect image displacement in a plurality of areas set on the image sensing plane, and a control microcomputer which makes a discrimination, on the basis of information output from these detection circuits, between a movement of a camera and a solo movement of a photographed object. The device thus accurately makes compensation for an image shake by judging the state of the image on the basis of information output from these detection circuits. The image shake detecting device further includes a computing circuit arranged to compute a quantity of an image shake on the basis of a difference in detecting timing of a feature point of the image and a sensitivity control circuit arranged to change the detection sensitivity of the shake detection circuits.Type: GrantFiled: July 26, 1999Date of Patent: April 9, 2002Assignee: Canon Kabushiki KaishaInventors: Masayoshi Sekine, Toshiyuki Nakajima, Takashi Kai, Katsuji Yoshimura, Masamichi Toyama
