Abstract:
1. An image processing apparatus, comprising: image input means for inputting a color image signal; image area determination means for determining an area characteristic in the color image signal; conversion means for converting the color image signal input by said image input means into an output image signal by an interpolating operation using a table memory, wherein the table memory stores interpolation data in each address, and higher order bits of the color image signal are used to define an address of the table memory in which interpolation data is stored, and lower order bits of the color image signal are used in the interpolating operation; color gamut determination means for determining a color gamut characteristic in the output image signal based on the higher order bits of the color image signal; correction means for making an MTF correction to the output image signal based on determination results of said image area determination means and said color gamut determination means; and image output means for visualizing the output image signal to which the MTF correction is made.
