Projection partitioning and aligning

A system comprising:

• a screen having regions actuatable to individualized reflectivities;
• a projector configured to project an area onto the screen;
• at least one sensor configured to sense the positioning of the area on the screen;
• and
• a controller configured to partition the area into blocks, each of the blocks including image pixels and corresponding to one of the regions and configured to align each of the blocks with its corresponding region of the screen.

A system comprising:

• a screen having regions actuatable to individualized reflectivities;
• a projector configured to project an area on the screen;
• and
• means for partitioning the area into distinct blocks of pixels having geometries and sizes substantially similar to corresponding regions of the screen;
• and
• means for aligning the blocks with their corresponding regions of the screen.

A computer readable medium comprising:

• instructions to actuate regions of a screen to individualized reflectivities;
• instructions to partition a projection area to be projected onto the screen into blocks of pixels;
• instructions to align each of the blocks with a corresponding one of the regions of the screen;
• and
• instructions to perform different image processing on at least two of the blocks.

A method comprising:

• actuating individual regions of a screen to have individualized reflectivities;
• partitioning a projection area to be projected onto the screen into blocks of pixels;
• aligning the blocks with corresponding regions;
• and
• altering a position of the blocks of the projected area on the screen.
