Abstract
A line blanker system for converting a stereoscopic image into a line-blanked stereoscopic image suitable for stereoscopic viewing on a standard non-interleaved display device is provided. The system includes a method for controlling the line blanker. According to the invention, one can enable and disable the line blanker, identify the first line of the image being processed and determine whether the first line is for viewing by the left eye or the right eye of a viewer. In addition, the invention includes a line doubler. The line doubler provides enhanced brightness and resolution by replacing the blanked line with a double of the line immediately adjacent to the blanked line.
Claims21
A method for controlling a line blanker, said line blanker being for converting a stereoscopic image into a line-blanked stereoscopic image by alternately blanking even and odd lines of said stereoscopic image, whereby said line-blanked image can be viewed on a standard non-interleaved display device by a viewer wearing shutter glasses having a left eye viewing portion and a right eye viewing portion, said method comprising:
- providing a stereoscopic image;
- converting said stereoscopic image to said line-blanked image;
- and
- providing a line blanker control signal embedded in said stereoscopic image, said line blanker being responsive to said control signal to enable or disable said line blanker,
- wherein said control signal is embedded within a first line signal of said line-blanked image.
A line blanker that converts a stereoscopic image into a line-blanked stereoscopic image, whereby said line-blanked image can be viewed on a standard non-interleaved display device by a viewer wearing shutter glasses having a left eye viewing portion and a right eye viewing portion, said line blanker comprising:
- a line interpolator that receives said stereoscopic image and alternately substitutes blanks for even or odd lines of said stereoscopic image;
- a line doubler that places each line of said stereoscopic image in a line buffer and fills each of said blanks with a line of said stereoscopic image located immediately above each of said blanks;
- an image fabrication unit that receives said stereoscopic image as adapted by said line interpolator and said line doubler and generates said line-blanked image;
- a line processor that receives said stereoscopic image and said line-blanked image and selects one of said images to transmit to said display device;
- and
- a control unit that monitors said stereoscopic image for a control signal and instructs said line processor which image to output based on said control signal, said control unit enables or disables said line blanker based on said control signal.
A line blanker that converts a stereoscopic image into a line-blanked stereoscopic image, whereby said line-blanked image can be viewed on a standard non-interleaved display device by a viewer wearing shutter glasses having a left eye viewing portion and a right eye viewing portion, said line blanker comprising:
- a line buffer that receives said stereoscopic image and alternately substitutes blanks for even or odd lines of said stereoscopic image;
- a line doubler that places each line of said stereoscopic image in a single line buffer and fills each of said blanks with a line of said stereoscopic image located immediately above each of said blanks;
- an image fabrication unit that receives said stereoscopic image as adapted by said line buffer and said line doubler and generates said line-blanked image;
- a line processor that receives said stereoscopic image and said line-blanked image and selects one of said images to transmit to said display device;
- and
- a control unit that monitors said stereoscopic image for a control signal and instructs said line processor which image to output based on said control signal, said control unit enables or disables said line blanker based on said control signal.
A line blanker that converts a stereoscopic image into a line-blanked stereoscopic image, whereby said line-blanked image can be viewed on a flat panel display device by a viewer wearing shutter glasses having a left eye viewing portion and a right eye viewing portion, said line blanker comprising:
- a line interpolator that receives said stereoscopic image and alternately substitutes blanks for even or odd lines of said stereoscopic image;
- an image fabrication unit that receives said stereoscopic image as adapted by said line interpolator and generates said line-blanked image;
- a line processor that receives said stereoscopic image and said line-blanked image and selects one of said images to transmit to said flat panel display device;
- and
- a control unit that monitors said stereoscopic image for a control signal and instructs said line processor which image to output based on said control signal, said control unit enables or disables said line blanker based on said control signal.
A line blanker that converts a stereoscopic image into a line-blanked stereoscopic image, whereby said line-blanked image can be viewed on an LCD projection system by a viewer wearing shutter glasses having a left eye viewing portion and a right eye viewing portion, said line blanker comprising:
- a line buffer that receives said stereoscopic image and alternately substitutes blanks for even or odd lines of said stereoscopic image;
- an image fabrication unit that receives said stereoscopic image as adapted by said line buffer and generates said line-blanked image;
- a line processor that receives said stereoscopic image and said line-blanked image and selects one of said images to transmit to said LCD projection system;
- and
- a control unit that monitors said stereoscopic image for a control signal and instructs said line processor which image to output based on said control signal, said control unit enables or disables said line blanker based on said control signal.
