Abstract
A device and a method are described for measuring a camera having an image sensor, in particular a fixed-focus camera, the device including: a camera support for accommodating at least one camera to be tested in at least one camera position, a collimator device for emitting collimator light of a test pattern having different object distances, a mirror system for deflecting the collimator light to the camera position, the mirror system having at least one first mirror device which is pivotable by a mirror adjustment device into multiple pivot positions, and a second mirror device having multiple second mirror units, the second mirror units reflecting the light emitted by the first mirror device in its different pivot positions to the camera position for imaging the test pattern in different image regions of an image sensor.
