Crosstalk cancellation in 3D displays
First Claim
1. A method for preparing image data for 3D images comprising left-eye and right-eye views for display, the method comprising:
- based on the image data for the left-eye and right-eye views identifying sets of pixels in each of the left-eye and right-eye views having pixel values insufficient to allow complete subtractive crosstalk cancellation;
selectively for the pixels in the sets determining amounts to increase pixel values of the pixels to allow complete subtractive crosstalk cancellation;
based on the determined amounts for the pixels in the sets establishing an amount or amounts to increase the pixel values;
preparing the image data by increasing the pixel values for at least some of the pixels in the sets by one or both of addition and scaling in the established amount or amounts.

Abstract
Image processing is performed to facilitate subtractive crosstalk cancellation in 3D images. In a global embodiment, pixel values are compressed to provide sufficient foot room for subtractive crosstalk cancellation. For video images the degree of compression may vary from frame to frame. Temporal filtering may be applied to reduce flicker. In a local embodiment luminance is added to and/or compression is performed in local areas to facilitate more complete subtractive crosstalk cancellation. The amount or added luminance or compression may be matched to the requirements of the local areas. Added luminance and/or compression may be made to vary smoothly in time and smoothly in space. Displays and other apparatus may be constructed to perform methods for partial or complete crosstalk cancellation.
