Real-time image scanning and processing

Apparatus for displaying at least one image with respect to a line-of-sight (LOS), with substantially no image latency as perceived by a human user, the LOS being determined between the head of a user and at least one coordinate system established in space, said at least one coordinate system and said displayed at least one image being in relative motion there between, the apparatus comprising:

• an image source, for providing at least one spatially unregistered image, said at least one spatially unregistered image comprising a plurality of pixels;
• a displaying unit, for displaying a spatially registered image on a displaying surface;
• and
• a display processor, coupled with said image source and said displaying unit, for spatially registering said at least one spatially unregistered image with said LOS,
• wherein said display processor comprises:
• a storage unit, for storing said at least one spatially unregistered image;
• an image processor, for iteratively selecting a pixel location on said displaying surface;
• and
• a pixel locator, coupled with said image processor, for respectively determining in said at least one spatially unregistered image, an unregistered pixel location corresponding to said selected pixel location on said displaying surface,
• wherein a pixel stored in said unregistered pixel location represents a spatially registered pixel in said selected pixel location on said displaying surface,
• wherein for each selected pixel location on said displaying surface, said display processor extracting said pixel stored in said unregistered pixel location and providing said pixel stored in said unregistered pixel location to said displaying unit, said displaying unit displaying said pixel stored in said unregistered pixel location in said selected pixel location on said displaying surface, and
• wherein for each said spatially registered image, at least one of said pixel stored in said unregistered pixel location extracted by said display processor being displayed by said displaying unit before at least another one of said pixel stored in said unregistered pixel location is extracted by said display processor, thereby displaying said at least one image with respect to said LOS with substantially no image latency as perceived by said human user as said displaying unit iteratively displays respective pixels in each said selected pixel location on said displaying surface.
