Patent number: 11934808Abstract: A screen transition aggregation device includes a calculation unit configured to calculate a degree of similarity between a transition destination screen and a transition source screen in order from an end screen in a screen transition diagram; and a generation unit configured to classify the transition destination screen and the transition source screen into groups based on a comparison between the degree of similarity and a threshold value, and to generate information indicating a transition relationship between the groups. Thus, the ease of grasping the specifications of an application that provides a function by screen transition is improved.Type: GrantFiled: May 31, 2019Date of Patent: March 19, 2024Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Toshiyuki Kurabayashi, Haruto Tanno, Yu Adachi, Hiroyuki Kirinuki, Yu Yoshimura

Patent number: 8896638Abstract: An initial light control value calculation section calculates the backlight's initial light control value K0 according to brightness of an inputted image signal for each area. A black area measurement section measures a black area S by obtaining ratio of the number of pixels satisfying Y?Y0 (Y: brightness signal level, Y0: black level threshold) in the screen. A minimum light control value output section determines a minimum light control value Kmin based on comparison between the measured black area S and a black area threshold S0 and outputs a maximum value permissible for the light control value as the value Kmin when the black area S is the threshold value S0 or less. An LED control signal calculation section outputs a control signal to LED light sources based on a light control value K1 as the higher one of K0 and Kmin.Type: GrantFiled: April 15, 2011Date of Patent: November 25, 2014Assignee: Hitachi Maxell, Ltd.Inventors: Hiroyuki Kurabayashi, Yasutaka Tsuru, Yuya Ogi, Kazuhiko Tanaka, Akihiro Shiraishi

Patent number: 8390640Abstract: A television device structured to automatically adjust the color temperature on the display screen in accordance with the viewing environment includes an external light detection unit or an optical sensor for detecting the illuminance and the tint of the ambient light, and an image quality control unit or a microcomputer for adjusting quality of the video image to be displayed on the display panel. The image quality control unit adjusts the color temperature of the video image to be displayed in accordance with the illuminance value and the tint value detected by the external light detection unit. The optical sensor includes an illuminance sensor for mainly detecting the visible light, and an infrared sensor for mainly detecting the infrared light. The illuminance value and the tint value are obtained based on the output values of those two sensors.Type: GrantFiled: November 10, 2009Date of Patent: March 5, 2013Assignee: Hitachi Consumer Electronics Co., Ltd.Inventors: Hiroshi Aoki, Akira Kitazume, Daisuke Honda, Naoya Oka, Yuki Nagano, Hiroyuki Kurabayashi, Akihiro Shiraishi, Toshiaki Ohyama

Publication number: 20110316829Abstract: A backlight of a liquid crystal display device is divided into a plurality of regions. A backlight area dimmer sets a dimming value for each of the regions of the backlight according to a characteristic amount of the input image. A backlight dimming limiter sets an upper limit and lower limit of the dimming value set by the backlight area dimmer. In this case, the backlight dimming limiter may set the upper and lower limits of the dimming value according to a combination of at least two pieces of information among illuminance information on the external light, category information on the input image and image mode information set by the user.Type: ApplicationFiled: April 21, 2011Publication date: December 29, 2011Inventors: Naoya OKA, Hiroyuki KURABAYASHI, Yasutaka TSURU, Kazuhiko TANAKA, Yuya OGI

Patent number: 6540077Abstract: The invention relates to a photographic roll film such as Brownie film, particularly to a sealing tape, used for the photographic roll film, which can seal a roll of film easily and reliably without the need for licking adhesive on a sealing tape as in a conventional one. The sealing tape includes a bonding portion and a release portion which are made of a single tape base. The bonding portion has a bond layer coated on the tape base for securing the sealing tape to a surface of light-shielding paper, the release portion made of a folded-over portion formed by folding over the tape base includes a tacky layer and a release layer inside the folded-over portion which are coated on the tape base separately and directly face each other and an end of the tape base is secured to the end portion of the bond layer.Type: GrantFiled: January 26, 2001Date of Patent: April 1, 2003Assignee: Fuji Photo Film Co., Ltd.Inventors: Mototada Yasui, Nobuo Sugiyama, Hiroyuki Kurabayashi

Patent number: 4668602Abstract: A peel-apart type instant film unit comprising an image receiving sheet separably adhered in a heat sealing manner to a mask member which is peeled apart from the former after the development thereof. There is provided therebetween a weak sealing layer comprising an adhesive layer of a thermoplastic polymer having hydrophilic groups and a separating layer which is alkali resistant and has a good separation property relative to the adhesive layer. The weak sealing layer can provide an easy separation between the separating and adhesive layers so as perfectly to transfer the adhesive layer to the image receiving sheet to provide a fine appearance and a writeable image frame on the image receiving sheet. The mask member is made of any polyethylene compounded paper sheets and is provided with a processing liquid-resisting layer inside the weak sealing layer for the purpose of preventing the permeation of processing liquid thereto.Type: GrantFiled: August 15, 1985Date of Patent: May 26, 1987Assignee: Fuji Photo Film Co., Ltd.Inventors: Shunichi Hosaka, Hiroyuki Kurabayashi, Jun Inose
