A testing apparatus (100) for an image capture device (401) includes a liquid crystal device (101). The liquid crystal device (101) includes an array of pixels (102), which may actively or passively be changed from a transparent state to an opaque or semi-opaque state. The array of pixels are capable of segmentation into a plurality of predefined regions (107), which may be columns (108) or rows (208). A liquid crystal device driver (105) is configured to actuate the predefined regions (107), individually and sequentially, in a sweep pattern across the liquid crystal device. The testing apparatus (100) may be used to measure a variety of parameters associated with image capture devices, including exposure duration, continuous shutter frequency, and flash-shutter lag. The testing apparatus (100) is capable of operation in a variety of ambient lighting conditions.
