A sequential pattern comprising contiguous black frames inserted between left and right 3D video and/or graphics frames may be displayed on an LCD display. The pattern may comprise two or three contiguous left frames followed by contiguous black frames followed by two or three contiguous right frames followed by contiguous black frames. The left and/or right frames may comprise interpolated frames and/or may be displayed in ascending order. The contiguous black frames are displayed longer than liquid crystal response time. 3D shutter glasses are synchronized with the black frames. A left lens transmits light when left frames followed by contiguous black frames are displayed and a right lens transmits light when right frames followed by contiguous black frames are displayed. A 3D pair of 24 Hz frames or two 3D pairs of 60 Hz frames per pattern are displayed on a 240 Hz display.

Each of the above stated applications is hereby incorporated herein by reference in its entirety.
Certain embodiments of the invention relate to communication systems. More specifically, certain embodiments of the invention relate to response time compensation for 3D video processing.
FIG. 1 is a block diagram of an exemplary 3D video and/or 3D graphics communication system, in accordance with an embodiment of the invention.
FIG. 2 is a block diagram that illustrates exemplary 3D video reception and/or display subsystems that may be operable to format left and/or right view 3D video and/or graphics frames and/or blanking frames, in accordance with an embodiment of the invention.
FIG. 3 is a block diagram that illustrates exemplary left view and right view 3D video and/or graphics frames, in accordance with an embodiment of the invention.
Certain embodiments of the invention can be found in a method and system for response time compensation for 3D video processing. In accordance with various embodiments of the invention, one or more processors and/or circuits in a 3D video and/or graphics processing device may generate formatted left view 3D video and/or graphics frames, right view 3D video and/or graphics frames and black frames in a specified sequential pattern. The specified sequential pattern may comprise at least two of the black frames that are inserted between the at least one left view 3D video and/or graphics frames and the at least one right view 3D video and/or graphics frames. The formatted left view 3D video and/or graphics frames, the right view 3D video and/or graphics frames and the at least two contiguous black frames may be displayed in order according to the specified sequential pattern, for example, on an LCD display device.
The specified sequential pattern may comprise two or three contiguous left frames followed by at least two contiguous black frames followed by two or three contiguous right frames followed by at least two contiguous black frames. One or more of the at least one left view 3D video and/or graphics frames may comprise one or more interpolated left view 3D video and/or graphics frames. Also, the at least one right view 3D video and/or graphics frames may comprise one or more interpolated right view 3D video and/or graphics frames. The at least one left view 3D video and/or graphics frames and the at least one right view 3D video and/or graphics frames may be displayed in an order that is ascending or that may comprise ascending and/or repeated left and right frames. Moreover, the at least two contiguous black frames of the specified sequential pattern may be displayed for a duration that exceeds liquid crystal display response time. A viewer's 3D shutter glasses may be synchronized with the specified sequential pattern based on the two or more contiguous black frames within the specified sequential pattern. For example, the 3D shutter glasses may be operable to adaptively synchronize with the specified sequential pattern. A left lens of a viewer's 3D shutter glasses may allow light to pass through to a left eye within an interval of display of the at least one left view 3D video and/or graphics frames followed by the at least two black frames and prior to display of the at least one right view 3D video and/or graphics frames. The right lens of the 3D shutter glasses may block light during the interval that transmission of light occurs in the left lens. Similarly, a right lens of the 3D shutter glasses may allow light to pass through to a right eye within an interval of display of the at least one right view 3D video and/or graphics frames followed by the at least two black frames and prior to display of the at least one left view 3D video and/or graphics frames. The left lens of the 3D shutter glasses may block light during the interval that transmission of light occurs in the right lens. The specified sequential pattern comprising content from a pair of left and right 3D 24 Hz frames may be displayed on a 240 Hz display device. Additionally, the specified sequential pattern comprising content from two pairs of left and right 3D 60 Hz frames may be displayed on a 240 Hz display device. In this manner, crosstalk comprising left and right 3D content may be mitigated.
FIG. 1 is a block diagram of an exemplary 3D video and/or 3D graphics communication system, in accordance with an embodiment of the invention. Referring to FIG. 1, there is shown a video transmission unit (VTU) 110, a communication network 120, a video reception unit (VRU) 130, a memory 116 and a 3D display device 114.
