Abstract
The present invention relates to an apparatus and method for generating mosaic images, wherein photographed content is displayed as a still image by a digital TV display or video monitor for an extended period of time. The apparatus of the present invention includes an animation analyzer for output of a motion vector of an input image, a coefficient calculator for calculating transformation and warping coefficients, a means for offsetting illumination differences, and storage for mosaic images. The present invention can advantageously be used for calculating a more accurate transformation coefficient, thereby generating mosaic images with minimal distortion.
