Method and system for the reduction of memory capacity required for digital representation of an image |
摘要 |
A method for compressing a first bit digital input representative of first pixel data into a second bit digital output representative of second pixel data, the method comprises the steps of defining a logarithmic function for converting the first bit digital input into the second bit digital output; replacing a portion of the logarithmic function with a polynomial function; and compressing the first bit digital input into the second bit digital output by utilizing the logarithmic and polynomial function.
