| 摘要 |
The invention relates to an image acquisition device (100) for acquiring a first image of an identification document in a first wavelength range and a second image of the identification document in a second wavelength range, comprising a document rest (101) for supporting the identification document, a displaceable guide slide (103), which is displaceable between a first holding position at a first distance from the document rest (101) and a second holding position at a second distance from the document rest (101), and an image camera (105) with an optical lens (107), wherein the optical lens (107) has a first focal point in the first wavelength range at the first distance, wherein the optical lens (107) has a second focal point in the second wavelength range at the second distance, and wherein the image camera (105) is arranged on the displaceable guide slide (103) and embodied to acquire the first image in the first wavelength range at the first holding position and to acquire the second image in the second wavelength range at the second holding position. |
