Display controller, three dimensional display, and method of reducing crosstalk

A method for reducing crosstalk between first and second images defined by respective sets of picture elements, to produce respective sets of crosstalk corrected picture elements, the method comprising the steps of:

• adding a grey level to the first image to form a first sum;
• adding the grey level to the second image to form a second sum;
• subtracting from the first sum an amount equal to a given fraction of the second image;
• and
• subtracting from the second sum an amount equal to a given fraction of the first image,
• wherein the method further comprises a calculation step of a partial result which is used to determine the crosstalk corrected picture elements for both the first and second images.

A stereoscopic display controller for supplying picture element data for N different views to a scanned stereoscopic display which comprises a plurality of picture elements, the stereoscopic display controller comprising:

• a memory comprising a two-dimensional array of memory elements mapped to pixels of the stereoscopic display;
• a memory controller arranged to write the picture element data for each image into a contiguous block of the memory elements and to read the picture element data from the memory in a row-by-row manner;
• at least one buffer for receiving at least a part of each row as it is read from the memory;
• a first data reordering circuit for reordering the picture element data contained in the buffer, and other data which is read from the memory but not contained in the buffer, to provide a stream of the picture element data in which the N views are interlaced;
• and
• a second data reordering circuit arranged to receive the stream of the picture element data and to reorder the picture element data for at least one color component.
