$ delta $-continuous [6] and $ delta $-perfect [5] functions are both introduced by T.~Noiri in the similar fashion as continuous and perfect functions. The purpose of the present paper is to investigate several properties of $ delta$-perfect functions and also to determine some topological properties which are preserved by $ delta$-continuous $ delta$-perfect functions
