1. A mobile terminal test apparatus that performs a conformance test of a mobile terminal, the apparatus comprising:
a reception antenna that receives a radio wave transmitted from the mobile terminal;
a positioner that adjusts a position of the mobile terminal;
a camera that captures an image of the mobile terminal; and
a control unit that
stores at least information on the position of the mobile terminal at a Peak point of a transmission radio wave and image data of the mobile terminal obtained by image capturing of the camera at the Peak point of the transmission radio wave, in a database as Peak point data of the transmission radio wave for each mobile terminal,
when the Peak point data of the transmission radio wave of the mobile terminal as a measurement target is stored in the database,
compares current image data to the image data of the Peak point data of the transmission radio wave, the current image data being obtained in a manner that the camera captures an image of the mobile terminal of which the position is adjusted by the positioner based on the information on the position of the mobile terminal in the Peak point data of the transmission radio wave, and
displays the current image data obtained by image capturing of the camera and the image data of the Peak point data of the transmission radio wave when an error between the position of the mobile terminal in the current image data obtained by image capturing of the camera and the position of the mobile terminal in the image data of the Peak point data of the transmission radio wave is greater than a predetermined threshold value,
wherein the control unit is configured to change the vertical rotation angle of the positioner and the horizontal rotation angle of the positioner by a predetermined step size.
