ABSTRACT:
A test apparatus and method for testing the zoom of a miniature digital camera module is presented. A combination of focus targets are illuminated by different colors of light and simultaneously viewed by the digital camera module. The focus targets range from a far target to a close target and are positioned in the apparatus accordingly. The zoom capability of the camera can be either electrical or manual, and the test apparatus can be adapted to either zoom configurations allowing the zoom of the camera lens to be controlled by a tester. The brightness of the image of the focus targets captured by the digital camera is monitored to determine whether the focus of the camera is maintained over the range of zoom.
