PURPOSE: An image testing apparatus and an image testing method are provided to efficiently remove defects on a printed circuit board by simultaneously measuring two-dimensional and three-dimensional image data. CONSTITUTION: An image testing apparatus(100) comprises a work stage(130), a projecting unit(110), an imaging unit(150), and a control unit(140). The work stage fixes a base member(120). The projecting unit comprises a lattice unit(112) and a projection lens(113). The imaging unit receives latticed image light reflected from a target object of the base member. The control unit controls the work stage, the projecting unit, and the imaging unit and tests the target object using the phase value of the target object and the received latticed image.
