Patent number: 8242973Abstract: An image processing apparatus receives first and second input image signals and generates first and second projection image signals for projecting images from first and second projectors so as to be superimposed on a screen. A storage unit stores, for each projection position on the screen, intensity ratios between projected light from the first and second projectors when viewing from first and second viewing position. An intensity correcting unit adds the first and second input image signals in proportions set for generating the first projection image signal and in proportions set for generating the second projection image signal, according to the stored intensity ratios. The first projection image signal is supplied to the first projector and the second projection image signal is supplied to the second projector.Type: GrantFiled: October 20, 2008Date of Patent: August 14, 2012Assignee: Sony CorporationInventors: Kenji Tanaka, Tetsujiro Kondo, Tetsushi Kokubo, Hitoshi Mukai, Hirofumi Hibi, Kazumasa Tanaka, Hiroyuki Morisaki

Patent number: 7899208Abstract: The present invention relates to image processing apparatus and method, a recording medium, and a program for providing reliable tracking of a tracking point. When a right eye 502 of a human face 504 serving as a tracking point is tracked in a frame n?1 and when a tracking point 501 appears as in a frame n, the tracking point 501 continues to be tracked. When, as in a frame n+1, the right eye 502 serving as the tracking point 501 disappears due to the rotation of the face 504 of an object to be tracked, the tracking point is transferred to a left eye 503, which is a different point of the face 504 serving as the object including the right eye 502. The present invention is applicable to a security camera system.Type: GrantFiled: January 6, 2005Date of Patent: March 1, 2011Assignee: Sony CorporationInventors: Tetsujiro Kondo, Tsutomu Watanabe, Tomoyuki Ohtsuki, Hitoshi Mukai, Nobuyuki Yamaguchi

Patent number: 7724298Abstract: The present invention relates to an image processing system and an image processing method, an image pickup apparatus and an image pickup method, and an image display device and an image display method, which can faithfully pick up and display the colors of an object. Slit light of an optical image of the object that has passed through a slit 42 is divided into a spectrum by a light divider 43. A light sensor 44 outputs image data based on the spectrum of the slit light of the optical image of the object. A micromirror array 74 causes the exiting of reflection light formed by extracting spectrum portions based on the image data from a spectrum of incident white light from a light divider 73. The spectrum portions of the reflection light exiting from the micromirror array 74 are synthesized by a spectrum synthesizer 77 and are projected onto a screen 111. The present invention is applicable to the image processing system.Type: GrantFiled: October 12, 2004Date of Patent: May 25, 2010Assignee: Sony CorporationInventors: Tetsujiro Kondo, Tetsushi Kokubo, Hitoshi Mukai, Hirofumi Hibi, Tsugihiko Haga, Kenji Tanaka
