We studied a family of lattice polarized K3 surfaces, which extends from the family of Kummer surfaces derived from principally polarized Abelian surfaces. Our family has two special properties: it originates from the resolution of a simple K3 singularity, and it can be parameterized naturally by Hermitian modular forms with four complex variables. In this paper, we presented two results: (1) determination of the transcendental lattice and the Neron-Severi lattice of a generic member in our family; (2) detailed description of the double covering structure associated with our K3 surfaces.
