Patent number: 8358262Abstract: An approach for coordinating backlight intensity and image luminance changes. For one aspect, in response to determining that a display-related event has occurred during a vertical frame period indicating a subsequent change associated with at least one of a backlight intensity and a frame buffer palette is to be undertaken, an interrupt is enabled. During subsequent interrupt processing, associated changes to the backlight intensity and the frame buffer palette are applied in a coordinated manner. For a specific implementation, an approach is provided for a graphics controller driver to synchronize response to changes in display backlight, color-space controls, and in the luminance of images, wherein said changes can come from different sources, occur at a different rates, and have different latencies, for the purpose of applying graphics settings responses such that those effects occur at a visually co-incident interval so as to substantially minimize discordant visual artifacts.Type: GrantFiled: June 30, 2004Date of Patent: January 22, 2013Assignee: Intel CorporationInventors: Anil A.

Patent number: 8345000Abstract: An information processing device performs a game process based on a tilt angle of an input device that can be rotated to any tilt about a predetermined axis. First, a game apparatus calculates a tilt angle representing the tilt of the input device. Then, the game apparatus determines whether the calculated tilt angle has transitioned across the boundary between the upper limit value and the lower limit value of the tilt angle. If the tilt angle has transitioned across the boundary, the tilt angle to be used in a predetermined information process is corrected to a predetermined value that is on one side of the boundary on which the tilt angle was before crossing the boundary.Type: GrantFiled: November 9, 2009Date of Patent: January 1, 2013Assignee: Nintendo Co., Ltd.Inventor: Takuhiro Dohta

Patent number: 8279214Abstract: The invention concerns a video processing for improving the picture quality of picture which are displayed on display devices like plasma display panels and all kind of display devices based on the principle of duty cycle modulation of light emission and for reducing the average power dissipation. The basic idea behind the invention is to generate only the required amount of sustain pulses that effectively produce light and to avoid generating unnecessary sustain pulses. To this end, the video range of the input video is increased in order to be equal to a nominal range, 255 in the case of a 8-bit coding, and a power level mode with a reduced number of sustain pulses is selected to keep constant the brightness of the image. The number of sustain pulses that do not produce light is reduced.Type: GrantFiled: November 9, 2006Date of Patent: October 2, 2012Assignee: Thomson LicensingInventors: Carlos Correa, Cédric Thebault, Rainer Zwing
