摘要： An image processing apparatus receives color data and includes a masking processing circuit for modifying the colors represented by the color data by processing each of the different color data received. The colors are modified according to other color data associated with each of the colors represented by the color data. The masking processing circuit includes a first memory for storing data representing each color and a second memory for storing data from the data derived after masking processing the data stored in the first memory. The color data and the other color data are used as addresses in the first and second memory. The number of bits of each color data used as an address for each respective color is larger than the number of bits for each of the other color data received at that portion of the memory.
