Abstract

We first examine how a video camera lens acts in concert with a CCD sensor array to produce an optical image that is limited by both spatial and temporal bandwidth with regard to its ability to represent a set of points in object space. We then relate these factors to human visual perception and discuss three video camera operating regimes distinguished by four separate types of intended camera usage. Next we suggest three lens designs to meet minimum imaging requirements imposed by each of these different situations. Our designs are based upon the use of injection molded plastics and incorporate aspheric surfaces to minimize the number of lens elements while providing integral mechanical mounting features to facilitate automated lens assembly. In all, we have attempted to reduce lens production costs while meeting the imaging criteria established for each type of video camera application.
