1. An apparatus comprising:
an image generator to:
generate a first image for a first image sensor based on a position and orientation of a display screen relative to the first image sensor; and
generate a second image for a second image sensor based on the position and orientation of the display screen relative to the second image sensor, first content in the first image to be shifted relative to corresponding second content in the second image by a shift amount, the shift amount based on a target depth to be tested; and
a calibration controller to:
cause the first and second images to be presented on the display screen; and
calibrate the first and second image sensors based on a difference between the target depth and a measured depth, the measured depth based on an analysis of the first and second images as captured by the first and second image sensors when the first and second images are presented on the display screen.
