<p>An image pick-up apparatus (1) which comprises a beam splitter (2) for splitting an image into sub-images and several image sensors (3, 4) for picking up the sub-images is provided with a depolarizing element (6) which reduces the linear polarization degree of the light incident on the beam splitter. The electronic image signals of the image sensors (3, 4) are combined so as to form an electronic image signal of a composite image in a combination unit (5). Because the linear polarization degree of the light incident on a mirror surface (27) of the beam splitter (2) is low, the differences between brightnesses of sub-images picked up by individual image sensors are small. Disturbances are thus counteracted in the composite image. The image pick-up apparatus is preferably used in an X-ray examination apparatus (10) in order to reproduce an X-ray image having a high spatial resolution and few disturbances.</p> |
