Abstract
In an image deforming method and an image deforming apparatus, a portion of an input image is geometrically deformed to be outputted therefrom. Input and output image buffers keep input and output image data items, respectively. An image deforming method and a partial deformation region are specified in an image deformation specification unit. For each pixel of the output image, a before-deformation coordinate value calculating section calculates coordinate values thereof before the deformation. A shift calculating section calculates a coordinate shift amount expressing a quantity of shift for each pixel of the output image between coordinate values of the pixel and those of the pixel before the deformation, and the coordinate shift amount is stored in a pixel reallocation map storage in the form of a pixel reallocation map. While reallocating pixels in accordance with the shift amount in the storage, a partial pixel deforming unit transfers values of the pixels from the input image buffer to the output image buffer.
