ABSTRACT:
The data bits of a first image data unit representing a first range of 0-255 continuous color tones are mapped to a second image data unit having an expanded bit count capable of representing a second range of continuous color tones greater the first range. Of the available colors tones in the second range, 256 color tones are selected and associated with the 256 data combinations achievable with the first image data unit. A decoder is used to convert each data combination in the first image data unit into its corresponding color tone from the second range, which defines its conversion into a second image data unit. In this manner, one can expand the range of displayable colors to approximate the display of true colors associated with a higher resolution without increasing the number of bits of the first image data unit, which is input to a driver IC by an MPU.
