1. An information processing system comprising:
a display device having a display screen on which an object is placed;
a camera having an image area in which the display screen is included;
an information processing apparatus that displays, on the display screen, a first display based on a captured image generated by the camera; and
a first polarization filter,
wherein the first polarization filter is located between a lens of the camera and the display screen when the lens of the camera faces the display screen, wherein
the information processing apparatus
analyzes the captured image to detect an object included in the captured image,
displays, in response to detection of the object from the captured image, a display indicating a position of the detected object as the first display on the display screen,
displays, on the display screen, a second display representing an object which is not placed on the display screen,
analyzes the captured image including the second display displayed on the display screen to detect the object, and
determines whether or not a direction of the first polarization filter is proper based on whether the object is detected or not in a result of the analyzing.
