A numerical integration is performed over the surface of a close-binary component described by a Roche model in order to produce a theoretical light curve. The loss of light during eclipses of close binary systems and the total light level at any particular phase are calculated by numerical quadrature of line-of-sight intensity values over the total projected area of a system. Effects of distortion by mutual tidal action and axial rotation, reflection, and limb as well as gravity darkening are taken into account, and effects of variations in different system parameters on typical theoretical light curves are examined. Four photometric light curves of the semidetached eclipsing binary U Sge are analyzed by Kopal's (1975) method and by the technique outlined; the latter is also used to analyze a photoelectric light curve of the contact eclipsing binary AW UMa. Improved photometric elements are obtained for the U Sge system, and the contact nature of the AW UMa system is confirmed.
