Patent number: 8311832Abstract: A hybrid-captioning system for editing captions for spoken utterances within video includes an editor-type caption-editing subsystem, a line-based caption-editing subsystem, and a mechanism. The editor-type subsystem is that in which captions are edited for spoken utterances within the video on a groups-of-line basis without respect to particular lines of the captions and without respect to temporal positioning of the captions in relation to the spoken utterances. The line-based subsystem is that in which captions are edited for spoken utterances within the video on a line-by-line basis with respect to particular lines of the captions and with respect to temporal positioning of the captions in relation to the spoken utterances. For each section of spoken utterances within the video, the mechanism is to select the editor-type or the line-based subsystem to provide captions for the section of spoken utterances in accordance with a predetermined criteria.Type: GrantFiled: July 13, 2008Date of Patent: November 13, 2012Assignee: International Business Machines CorporationInventors: Kohtaroh Miyamoto, Noriko Negishi, Kenichi Arakawa

Publication number: 20120062763Abstract: According to one embodiment, an image processing apparatus includes a color mixture correction unit. The color mixture correction unit corrects the mixture of colors caused when an incident light having passed through color filters corresponding to neighboring pixels enters a target pixel. The color mixture correction unit references the signal level of the target pixel and the signal levels of the neighboring pixels. The color mixture correction unit calculates a correction amount corresponding to the signal level of a red pixel which is the neighboring pixel. The color mixture correction unit performs a calculation on the signal level of the target pixel using the correction amount.Type: ApplicationFiled: July 21, 2011Publication date: March 15, 2012Applicant: KABUSHIKI KAISHA TOSHIBAInventors: Shiroshi KANEMITSU, Kenichi ARAKAWA, Kazuhiro TABUCHI, Takaaki KAWAKAMI

Patent number: 7729917Abstract: A device of the present invention obtains a character string of a speech recognition result and a confidence factor thereof. A time monitor monitors time and determines whether or not processing is delayed by checking the confidence factor and time status. When the processing is not delayed, a checker is asked to perform manual judgment. In this event, speech is processed and the manual judgment of the speech recognition result is performed on the basis of the processed speech. When the processing is delayed, automatic judgment is performed by use of the confidence factor. When the character string is judged to be correct as a result of the manual judgment or the automatic judgment, the character string is displayed as a confirmed character string. When the character string is judged to be incorrect, automatic correction is performed by matching on the basis of a next candidate obtained by the speech recognition, texts and attributes of the presentation, a script text, and the like.Type: GrantFiled: March 21, 2007Date of Patent: June 1, 2010Assignee: Nuance Communications, Inc.Inventors: Kohtaroh Miyamoto, Kenichi Arakawa, Toshiya Ohgane

Publication number: 20100033601Abstract: A solid-state imaging device includes a plurality of pixel units, a reference voltage generator circuit, a cancellation unit, an analog-to-digital converter unit, a latch circuit, and a video processing unit. The plurality of pixel units output a reset signal serving as a first reference level of a video signal and the video signal, the video signal being output in units of two or more of the pixel units simultaneously to two or more of the signal lines. The reference voltage generator circuit generates a clamp voltage. The cancellation unit calculates the difference between a first addition and a second addition. The analog-to-digital converter unit digitizes the subtraction result. A latch circuit latches the result obtained at the analog-to-digital converter unit. The video processing unit terminates and starts the signal process in units of the pixel unit in a period when the clamp voltage is not generated.Type: ApplicationFiled: August 6, 2009Publication date: February 11, 2010Inventors: Takahiro MATSUDA, Kenichi Arakawa
