Patent number: 8189951Abstract: A technical problem is to inhibit variation in the correction between frames of a moving image while maintaining a correction amount of the overall image. The video signal display device has an attraction point determination portion (104), a corrected center position storage portion (105), a corrected center position determination portion (106), a correction parameter creation portion (107), and a correction portion (108), and performs correction such that the corrected center position is gradually moved toward an attraction point. The video signal display device achieves the same effect as methods that suppress correction variability by adjusting the correction amount, while also inhibiting correction variability.Type: GrantFiled: May 14, 2009Date of Patent: May 29, 2012Assignee: Panasonic CorporationInventors: Bunpei Toji, Shinya Kiuchi

Patent number: 8159598Abstract: Attempts to achieve a higher resolution and a higher frame rate of a distance image when a distance to an object within a target space is estimated using the TOF method would cause CCD saturation due to shot noise or environment light, and lower distance precision. A distance estimation apparatus illuminates an object with illumination light for distance estimation emitted from a light source that can emit light (electromagnetic wave) having a predetermined illumination frequency, receives reflected light of the illumination light, obtains information about the distance from the apparatus to the object, generates distance image data based on the distance information, extracts edge information of a color image formed using a visible light component obtained in synchronization with the reflected light, and corrects distance information of a target part of the distance image using distance information of a neighboring part of the target part based on the edge information.Type: GrantFiled: August 18, 2009Date of Patent: April 17, 2012Assignee: Panasonic CorporationInventors: Tatsumi Watanabe, Yasuhiro Kuwahara, Takeshi Ito, Bumpei Toji, Daisuke Sato, Shinya Kiuchi, Yoshiaki Owaki

Patent number: 8155438Abstract: A specific color-adjusting stage adjusts data of an inputted color with respect to a specific color. A total color-adjusting stage adjusts the data of the inputted color with respect to a total color. The specific color-adjusting stage and the total color-adjusting stage are provided in parallel. A composing unit composes linearly an output of the specific color-adjusting stage and an output of the total color-adjusting stage. When a degree that the total color-adjusting stage adjusts the data of the inputted color increases, then a degree that the specific color-adjusting stage adjusts the data of the inputted color decreases, and vice versa.Type: GrantFiled: May 12, 2008Date of Patent: April 10, 2012Assignee: Panasonic CorporationInventors: Tsuyoshi Hirashima, Jun Ikeda, Shuichi Ojima, Ryouta Hata, Shinya Kiuchi

Publication number: 20110063437Abstract: Conventionally, there has been a danger that CCD saturation may occur because of the influence of the shot noise and the environment light if a higher resolution of a distance image showing the distance to an object present in a target space and a higher frame rate are achieved when the distance image is estimated by the TOF method, and the distance accuracy may degrade. An emission frequency selecting unit (7) receives light (S2) reflected from the object when a light source does not emit light and selects illumination light (S1) having an emission frequency insusceptible to the environment light according to the frequency analysis of the reflected light (S2). An image creating unit (6) selects a light source emitting the illumination light having the optimum emission frequency from among prepared light sources (9A to 9N), receives reflected light of the illumination light from the selected light source, and creates the distance image showing the distance to the object.Type: ApplicationFiled: July 29, 2009Publication date: March 17, 2011Inventors: Tatsumi Watanabe, Yasuhiro Kuwahara, Takeshi Ito, Bumpei Toji, Daisuke Sato, Shinya Kiuchi, Yoshiaki Owaki
