ABSTRACT:
A color signal transforming apparatus of the type in which three or four input signals are each divided into higher bits and lower bits, and output signals are formed by calculating basic data obtained from the combinations of the higher bits and the combination of interpolation data obtained from the combinations of the higher bits and the lower bits. The color signal transforming apparatus comprises an address translation memory for receiving the combination of higher bits as an address signal and transforming the address signal to another address signal, correcting data storing unit for outputting a calculation signal for the lower bits in response to an address signal as the combination of the higher bits, and lower-bit correcting calculating unit for correcting the lower bits by using the output signal of the correcting data storing unit to remarkably reduce the total memory capacity required for a color signal transforming apparatus.
