The apparent contour of  a smooth surface is considered as the set of singularities of a projection mapping of the surface, and we can investigate it in terms of singularity theory.   What information of a surface can we get from the apparent contour? In this talk, we show some results to the question. Especially, we discuss on the case when the apparent contour itself has a singularity, and show relations between surfaces and the apparent contours.
