Abstract
In at least one implementation, characterizing veiling glare-corrected crosstalk for a 3D display system is implemented by a method that includes identifying a first image of a display presenting an interleaved fringe pattern on the display. A non-interleaved gray code pattern is generated having the same period as the fringe pattern. A second image of the display presenting the gray code pattern on the display is identified. A more accurate intrinsic crosstalk for the display is determined based on the first image and the second image by correcting for veiling glare present in the optical measuring device.
Claims20
A method comprising:
- identifying a first image of a display presenting a fringe pattern on the display;
- generating a gray code pattern having a same period as the fringe pattern;
- identifying a second image of the display presenting the gray code pattern on the display;
- and
- determining an intrinsic crosstalk for the display based on the first image and the second image.
A system for characterizing crosstalk in an autostereoscopic display, the system comprising:
- at least one processor;
- a computer-readable storage medium operatively coupled to the at least one processor;
- and
- program instructions stored on the computer-readable storage medium that, when executed by the at least one processor, direct the system to perform operations comprising:
- identifying a first image of a display presenting a fringe pattern on the display;
- generating a gray code pattern having a same period as the fringe pattern;
- identifying a second image of the display presenting the gray code pattern on the display;
- and
- determining an intrinsic crosstalk for the display based on the first image and the second image.
A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform operations comprising:
- identifying a first image of a display presenting a fringe pattern on the display;
- generating a gray code pattern having a same period as the fringe pattern;
- identifying a second image of the display presenting the gray code pattern on the display;
- and
- determining an intrinsic crosstalk for the display based on the first image and the second image.
