Publication number: 20020047929Abstract: An OSD including a display device for displaying and storing OSD data sets is set forth. The OSD includes an alignment system, associated with the display device. The alignment system aligns a first OSD data set with a second OSD data set. Aligning the OSD data sets reduces noise from the display device when the second OSD data set replaces the first OSD data set on the display system. A method of reducing noise in an OSD, including a memory device having memory cells for storing data, is also set forth. The method reduces noise in updating the OSD. The method includes the following steps. First, a no operation (NOP) code is stored in the memory cells where no change in data is required to update the OSD. Next, the OSD is updated by storing updated data in the memory cells where a data change is required to update the OSD.Type: ApplicationFiled: November 12, 1998Publication date: April 25, 2002Inventors: HAREL WHEITZ, MASANOBU KIMOTO

Patent number: 6259484Abstract: A method and apparatus for centering an active video signal on a display screen is described. In one embodiment, the method includes calculating an initial positioning value, which corresponds to an initial position of the active video signal on the display screen. A target positioning value is then determined using linear interpolation. The target positioning value is a rough estimate and provides a big pre-jump of the active video signal from the initial position to a target position, which positions the active video signal near the center of the display screen. A bi-sectional fine tuning technique may then be utilized to center the active video signal on the display screen. This method may be performed using a feedback loop that comprises a microcontroller, a digital signal processor, and an on-screen display circuit.Type: GrantFiled: October 1, 1998Date of Patent: July 10, 2001Assignees: Sony Corporation, Sony Electronics, Inc.Inventors: Libiao Jiang, Masanobu Kimoto

Patent number: 5808693Abstract: A video display apparatus capable of receiving multiple video input signals and of reducing its power consumption when each of those signals becomes inactive. Power consumption is reduced by selecting from a number of power saving modes. Each power saving mode has an associated recovery time as well as an associated amount of power savings. Recovery time is minimized by determining which of the video input signals is most likely to become active first, assigning a high priority to that signal and selecting a power saving mode based on characteristics of that signal. The likelihood of reactivation of a signal is determined by detecting the absence of normal vertical and/or horizontal synchronization signals.Type: GrantFiled: November 6, 1996Date of Patent: September 15, 1998Assignee: Sony CorporationInventors: Hiroshi Yamashita, Yasunori Mori, Masanobu Kimoto
