US Patent 9270900 Movie processing apparatus and control method therefor

A movie processing apparatus includes an input unit that inputs an input image. A memory control unit stores, in a memory, a deformation image obtained by executing an image deformation process for the input image using a deformation parameter. A determination unit determines, from a memory region in which the deformation image is stored, a readout region to be accessed for obtaining an output image, on the basis of a size of the input image, a size of the output image, and the deformation parameter. A readout unit configured to access the readout region reads out pixel data included in the deformation image. An output unit outputs the image based on the pixel data readout by the readout unit.
