A first group of interpolation calculators performing interpolation by mean preserving interpolation calculation, and a second group of interpolation calculators performing interpolation by interpolation other than the mean preserving interpolation calculation are provided. Each of the interpolation calculators performs interpolation calculation for the missing pixel to calculate an interpolation candidate value (M(h)), and calculates test interpolation values (M(t)) treating pixels in a vicinity of the missing pixel as test pixels. A decider () selects one of the plurality of interpolation calculators based on results of the test interpolation. An outputter () selects the interpolation candidate value outputted from the interpolation calculator selected by the decider (), among the plurality of interpolation candidate values (M(h)), and outputs the selected interpolation candidate value. Interpolation can be performed such that the interpolated pixel does not look unnatural, and yet the storage capacity and the data processing amount that are required are relatively small.

A method for manufacturing a decorative object, which enables manufacturing of a decorative object, on which a random concavo-convex structure is formed, such as non-glossy finish, with a uniform product appearance, while maintaining operating efficiency is described. The method for manufacturing a decorative object includes the steps of coating a concavo-convex surface having a concavo-convex structure with a coating solution including a resin component, transferring the concavo-convex structure to a transfer surface to form a resin layer having the transfer surface, and to obtain a transfer member comprising the resin layer, and decorating a surface for decoration by pressing the transfer surface of the transfer member against the surface for decoration including a thermoplastic resin while heating.

In an image processing for correcting a distorted image obtained by photography by use of a super-wide angle optical system such as a fisheye lens or an omnidirectional mirror, to obtain an image of a perspective projection method, a composite index (Rn) combining a height on the projection sphere with a distance from the optical axis is computed (), and a distance (Rf) from an origin in the distorted image is computed (), using the composite index (Rn). Further, two-dimensional coordinates (p, q) in the distorted image are computed (), using the distance (Rf) from the origin, and a pixel value in an output image is determined using a pixel at a position in the distorted image specified by the two-dimensional coordinates, or a pixel or pixels neighboring the specified position. It is possible to perform the projection from the projection sphere to the image plane, that is, the computation of the coordinates on the coordinate plane, while restricting the amount of computation.
