Abstract
Various approaches in which an image-recording parameter is varied between a plurality of images of an object and a stereo image pair is displayed on the basis of the images recorded thus are described. Here, in particular, the image-recording parameter can be a focal plane or an illumination direction.
Claims15
A method for presenting stereo images, comprising:
- recording a plurality of images of an object by an image-recording device, wherein an image-recording parameter is varied over the plurality of images,
- determining a first result image and a second result image by a computer device, wherein at least two images of the plurality of images are combined in each case for calculating the first result image and the second result image, wherein the first result image and the second result image form a stereo image pair for presenting stereo images,
- wherein the image-recording parameter comprises an illumination direction such that the plurality of images are recorded with different illumination directions, and
- wherein determining the first result image and the second result image comprises:
- calculating a first phase-contrast image, which has an increased phase contrast in a first direction, and a second phase-contrast image, which has an increased phase contrast in a second direction that differs from the first direction, based on the plurality of images;
- calculating the first result image based on the first phase-contrast image and the second phase-contrast image;
- and
- calculating the second result image based on the first phase-contrast image and the second phase-contrast image.

An apparatus, comprising:
- an image-recording device for recording a plurality of images of an object, wherein the image-recording device is configured to vary an image-recording parameter over the plurality of images, and
- a computing device for determining a first result image and a second result image on the basis of the plurality of images, wherein at least two images of the plurality of images are combined in each case for the first result image and the second result image such that the first result image and the second result image form a stereo image pair,
- wherein the image-recording parameter comprises an illumination direction such that a multiplicity of images are recorded with different illumination directions, and
- wherein determining the first result image and second result image comprises:
- calculating a first phase-contrast image, which has an increased phase contrast in a first direction, and a second phase-contrast image, which has an increased phase contrast in a second direction that differs from the first direction, based on the multiplicity of images;
- calculating the first result image based on the first phase-contrast image and the second phase-contrast image;
- and
- calculating the second result image based on the first phase-contrast image and the second phase-contrast image.
