Abstract
A device comprises an input unit, a motion acquisition unit, a matrix operation unit, and a drawing unit. The input unit implements sequential input of a first frame image and a second frame image. The motion acquisition unit acquires motion data between the first frame image and the second frame image. The matrix operation unit calculates a projection matrix to project the output frame image to the second frame image, from a first matrix including a rolling shutter distortion component, a second matrix including at least one of a parallel translation component in directions perpendicular to an image-shooting direction and a rotation component with respect to the image-shooting direction, and an auxiliary matrix including a motion component not included in the first matrix and the second matrix. The drawing unit generates the output frame image from the second frame image by using the projection matrix.
