The invention provides an N-lens solid digital camera, consisting of N (N is not less than 2) photographing units and a bus module. The N-lens solid digital camera is characterized in that a plurality of random photographing units are organically connected in series by the bus module so as to form a complete solid photographing device. The type of the N-lens solid digital camera facilitates the requirement of different purposes. Furthermore, the modularization structure avoids repeated elements, greatly saves the development expense, production expense and maintenance expense of the products, reduces the cost of the products, and is beneficial to the generalization and application of the solid images.
