A device comprises a memory array in which a plurality of codewords is stored. Each codeword comprises an error correction code and a data block that comprises a plurality of units of data. The device further comprises an error code correction module coupled to the memory array. When multiple units of data are to be read from the device for an address, a codeword stored in a location associated with the address is fetched from the memory array, the error code correction module decodes the codeword and corrects any errors in the data block for that codeword, and the multiple units of data are read from the corrected data block.

A method and apparatus for converting a color digital image into a grayscale digital image is disclosed. First, each green intensity value in the color digital image is copied into a corresponding pixel location of the grayscale digital image. Then for each red intensity value in the color digital image, the red intensity value is adjusted to match a local dynamic range of green intensity values. The adjusted red intensity value is inserted into the corresponding pixel location of the grayscale digital image. Then for each blue intensity value in the color image, the blue intensity value is adjusted to match a local dynamic range of green intensity values. The adjusted blue intensity value is inserted into the corresponding pixel location of the grayscale digital image.
