ABSTRACT:
A digital camera module (100) includes a barrel (1), an IR-cut filter (3) and at least one lens element (4). The IR-cut filter is fixed to the barrel. The at least one lens element is received in the barrel and is disposed behind the IR-cut filter so that incoming light firstly passes through the IR-cut filter, then passes through the at least lens element. The IR-cut filter may protect the at least one lens element so as to improve the quality of the digital camera.
