1. An image processing apparatus, comprising:

  • parameter setting means which has a setting of a parameter concerned with at least one of pan, tilt, zoom and rotation for cutting out a region to be displayed in an image taken in by a lens;

    geometrical position calculation means for calculating a geometrical position of each pixel in input side image data based on an output signal of imaging means, the each pixel corresponding to each pixel on an output screen, in order to perform predetermined transformation of a geometrical position of an image in the region based on the parameter;

    an address table for storing table information which is combined information obtained by correlating an input side address, as an address of the each pixel of the input side image data based on calculation results of the geometrical position calculation means, to an output side address as a reference which is an address of the each pixel on the output screen; and

    address matching means which checks the input side address of the each pixel of the input side image data, loaded in real time, against the input side address stored in the address table, and when both input side addresses are coincident, combines the input side image data at the input side address with the corresponding output side address to form output side image data, and also sends out the output side image data.
