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.
Compact Camera Module (CCM) is widely used in PDAs, Cellular phones and PC web cameras. Nowadays CCM image quality level should match with photo-quality in that frame, optics plays an important role. Among the whole set of optical parameters, flare is particularly threatening as it can waste the world-best-design associated to the world-best-manufacturing-process optics resulting to a simple piece of plastic without any value. Because it acts at the border between optical designer and mechanical designer fields, it is a challenging parameter to study. In this paper, after defining Flare parameter, we show a powerful method for tracking Flare among a complete CCM, through the use of the sensor's emitted intensity diagram. Following this procedure will prevent from random time consuming calculations on flare topic.
