Abstract

An apparatus provides an image on the basis of a plurality of input images. The apparatus includes a first stage having at least a first and a second combiner, each of the combiners including a first storer for storing image data of the input images, a first processor for processing the image data of the input images into an intermediate image, and a second storer for storing image data of the intermediate image. The apparatus further includes a second stage having at least one further combiner, the further combiner including a third storer for storing image data of those intermediate images which are stored in the second storer of the first stage, a second processor for processing the image data from the third storer, so as to combine the image data of the intermediate images into the image, and a fourth storer for storing image data of the image.

Claims

1. An apparatus for providing an image of a subarea of an object on the basis of a plurality of input images, comprising:

a first stage comprising at least a first combiner and a second combiner, each of the combiners comprising;

a first storer for storing image data of the input images, the input image comprising a subarea of the object which comprises any geometry and arrangement,

a first processor for processing the image data of the input images into an intermediate image as a function of a predefined parameter for geometrically aligning the input images, and

a second storer for storing image data of the intermediate image,

wherein the input images of the first combiner and of the second combiner differ from one another;

a second stage comprising at least one further combiner, the further combiner comprising;

a third storer for storing image data of those intermediate images which are stored in the second storer of the first stage,

a second processor for processing the image data from the third storer as a function of a predefined parameter for geometrically aligning the input images, so as to combine the image data of the intermediate images into the image, and

a fourth storer for storing image data of the image; and

a controller for defining a first parameter for geometrically aligning the input images for the processor of the first combiner, a second parameter for geometrically aligning the input images for the processor of the second combiner, and a third parameter for geometrically aligning the intermediate images for the processor of the further combiner on the basis of the subarea of the object, the controller being coupled to the processors.

2. The apparatus as claimed in claim 1, wherein the first storer of the first stage are further coupled to different individual sensors comprising any imaging surface areas and imaging geometries.

3. The apparatus as claimed in claim 1, wherein the first or second processor is implemented to manipulate the image data, on the basis of a further parameter, with regard to the levels of intensity of individual pixels.

4. The apparatus as claimed in claim 1, wherein the storers are implemented to store image data of a plurality of input images, intermediate images or images.

5. The apparatus as claimed in claim 1, comprising a plurality of stages which each comprise combiners implemented to make the image data of an intermediate image of a stage available as image data of the input images of the next stage up.

6. The apparatus as claimed in claim 1, wherein the first stage comprises a multitude of combiners, and the controller is implemented to adapt the parameters, on the basis of the subarea of the object, such that at least the image data of an input image is discarded and is not processed into an intermediate image.

7. A method of providing an image of a subarea of an object on the basis of a plurality of input images, comprising:

defining first, second and third parameters on the basis of the subarea of the object;

receiving image data of first input images, the input image comprising a subarea of the object which comprises any geometry and arrangement;

processing the image data of the first input images into a first intermediate image as a function of the first predefined parameter for geometrically aligning the first input images;

providing the first intermediate image;

receiving image data of second input images;

processing the image data of the second input images into a second intermediate image as a function of the second predefined parameter for geometrically aligning the second input images;

providing the second intermediate image;

processing the image data of the first intermediate image and of the second intermediate image into the image as a function of the third predefined parameter for geometrically aligning the intermediate images; and

providing the image.

8. A computer program comprising a program code for performing the method of providing an image of a subarea of an object on the basis of a plurality of input images, the method comprising:

defining first, second and third parameters on the basis of the subarea of the object;

receiving image data of first input images, the input image comprising a subarea of the object which comprises any geometry and arrangement;

processing the image data of the first input images into a first intermediate image as a function of the first predefined parameter for geometrically aligning the first input images;

providing the first intermediate image;

receiving image data of second input images;

processing the image data of the second input images into a second intermediate image as a function of the second predefined parameter for geometrically aligning the second input images;

providing the second intermediate image;

processing the image data of the first intermediate image and of the second intermediate image into the image as a function of the third predefined parameter for geometrically aligning the intermediate images; and

providing the image,

when the program code is executed on a computer.
