Compact Camera Module (CCM) is widely used in PDA, Cellular phones and PC web cameras. In this paper, a complete list of specifications of optical parameters have been set up from a CCM End User standpoint. Optical parameters are classified into four main sections: first order parameters, image quality parameters, opto-mechanical parameters and environmental parameters. In each section, parameter is defined in parallel with sensor characteristics and final application requirements as well as tailored specificities. Additionally, we have defined parameters for flare discrimination and IR cut-off filter for which we have set up the matching levels of acceptance.
