1. A test apparatus for measuring electromagnetic interference (EMI) of an image sensor integrated circuit (IC) device, the test apparatus comprising:

  • an EMI test jig configured to drive a mounted image sensor IC device on one or more test conditions;

    an electromagnetic (EM) shielding box configured to shield external EM waves from other directions except an upper direction, the EM shielding box accepting the EMI test jig;

    an EM emission sensing probe configured to sense EM emissions from the image sensor IC device, the EM emission sensing probe being separated from and adjacent to the image sensor IC device in the upper direction when sensing EM emissions; and

    a spectrum analyzer configured to connect to the EM emission sensing probe, the spectrum analyzer configured to evaluate the EM emissions from the image sensor IC device.
