Image recording device and method for recording images

Abstract

For image recording purposes, objects are illuminated at multiple lighting angles. A detector captures multiple images (41-43) of the object for the multiple illumination angles. The electronic evaluation means applies an image correction to said plurality of images (41-43), said image correction comprising a rectification (T 1 , T 2 , T 3 ), where the correction (T 1 , T 2 , T 3 ) depends on said illumination angle used when recording the corresponding said image (41-43). The corrected images (44-46) can be combined.

Description

technical field [0001] Exemplary embodiments of the present invention relate to apparatuses and methods for recording images. In particular, example embodiments relate to apparatus and methods that facilitate computational correction of optical aberrations. Background technique [0002] Modern optical systems must meet increasingly stringent requirements in terms of image quality. Important aberrations that should be kept low by the configuration of the optical system include, for example, field curvature and astigmatism. In the case of field curvature, the image appears in different planes along the optical axis depending on the point of view. Therefore, field-dependent defocus aberration occurs for a planar image field (eg, a camera chip). [0003] Such aberrations can be mitigated using high-precision and high-quality optical units. This often results in complex, large and expensive optical systems. Furthermore, a large number of lenses may increase the susceptibilit...
