Abstract: A workpiece has a body (3) and a wear-resistant hard coating system (HLo), which system comprises a layer of the following composition: (Al1-a-b-cCraBbZc)X where X is at least one of: N, C, CN, NO, CO, CNO; Z is at least one of: W, Mo, Ta, Cb (Nb). For a, b and c specific ranges of values are valid.

Abstract: An image special effect apparatus capable of realizing the illumination effects corresponding to various image special effects if an illumination effect pattern is not previously determined and the shape of the effect face changes rapidly is provided. An image special effect apparatus 100 for adding an illumination effect using light from a light source when viewed from an arbitrary eye point in a face having a curved face to image information concerning an input image and outputting a video signal provided by mapping the image information to the face generates a normal vector at a position of the face based on rectangular coordinate data and the shape of the face, a normal vector generation section 110, generates reflectivity of the light in an eye point direction by calculation of A (2(L·N)N?2L)·V of an expression using the normal vector, a light source direction unit vector, an eye point vector V, and an arbitrary value A, and creates the image information based on the image and the reflectivity.
