Claim One:
1. A video signal processing apparatus, comprising: a first calculator that receives a plurality of original input image frames, each of which having a different non-linear distortion, and calculates first coordinate conversion formulas, corresponding to each of the original input image frames, correcting non-linear distortion corresponding to a cropped region, capturing an object of each of the frame images; a distortion correction and interpolation processor that generates a plurality of distortion corrected images by performing distortion correction on the cropped region of each of the original input frame images according to each of the first coordinate conversion formulas and generates a plurality of interpolation processed images by performing interpolation processing on each of the distortion corrected images; a second calculator that calculates second coordinate conversion formulas correcting the interpolation processed images so that a position of the object captured in each of the interpolation processed images matches each other; an image coordinate conversion formula calculator that calculates integrated coordinate conversion formulas by integrating the first coordinate conversion formulas and the second coordinate conversion formulas; a pixel coordinate converter that generates pixel rearranged images by performing rearrangement of pixel coordinates on at least the cropped region of each of the original input frame images using the integrated coordinate conversion formula corresponding to each of the original input image frames; and a synthesizer that generates a synthesized image by synthesizing the rearranged images.
