description In a method of testing an image sensor, at least one test image is captured using the image sensor that is a device under test (DUT). A composite image is generated based on the at least one test image. A plurality of frequency data are generated by performing frequency signal processing on the composite image. It is determined whether the image sensor is defective by analyzing the plurality of frequency data.
