Photographic camera simulation systems working from computer memory

摘要: A camera field-of-view is mapped with full depth-of-focus into electronic memory. Data concerning image intensities at selected points in space are stored, along data the distances between and these space. Images any focus can be generated by scanning memory during a reading thereof convolving intensity an adjustable-bandwidth low-pass spatial filter. The bandwidth of that filter adjusted dependent on This storage retrieval procedure conserves size required to store retrieve images depth-of-focus.
