ABSTRACT:
A method of displaying digital samples with enhanced image details on a raster display using a limited set of brightness values is provided. Digital samples are interpolated and stored as pixel information in high resolution intensity memory. An adaptive mapping process maps the high resolution intensity information to low intensity brightness information in a manner so as to maximize image details. An equal number of brightness levels from light to dark are allocated in each column along the sweep. An adaptive recombination process combines past and present brightness information in a manner that best preserves image details when the temporal behavior of the display image is changing. A raster display device is employed to display the image which is stored in the display memory as pixels arranged by row and column.
