Abstract: The first aspect of this disclosure is related to a computer-based method for measurement of a plurality of optical foci, comprising the steps: measuring a first focus; obtaining one or both of: a) a focus range for a measurement of a second focus, wherein the focus range is based on the first focus; b) a starting value for a measurement of a second focus, wherein the starting value is based on the first focus; measuring the second focus with the obtained focus range and/or staring value; discarding the second focus, if the second focus is measured as an extreme value of the focus range; measuring a third focus.

Abstract: The invention relates to a data processing device for an imaging apparatus, the device being configured to obtain a length threshold value, to access input image data representing at least one digital input image, wherein the input image data comprise a shading signal representing a brightness decrease towards the edges of the at least one digital input image, and a content signal representing image features of the at least one digital input image, the image features having a length that is smaller than the length threshold value, to compute a baseline image based on the input image data and the length threshold value, wherein the baseline image is representative of an estimate of the shading signal, to generate at least one digital output image representative of an estimate of the content signal by at least one of a) subtracting the baseline image from the input image data and b) dividing the input image data by the baseline image. Advantageously, the data processing device allows a shading correction without the need for obtaining any separate background image or reducing the image size. The invention also relates to a computer-implemented method and a method for operating such an imaging apparatus. Further, the invention relates to a computer program and a computer-readable medium. Lastly, the invention relates to a neural network device trained by means of the data processing device or the computer-implemented method.

Abstract: An image processing apparatus for determining a focused output image in a passive autofocus system is configured to retrieve a set of input images and compute a baseline estimate for at least one input image. The baseline estimate represents image structures in the input image. The image structures have a length scale larger than a predetermined image feature length scale. The image processing apparatus is further configured to compute a set of output images, wherein each output image of the set of output images is computed based on one of a different input image of the set of input images and the at least one baseline estimate for the different input image and the at least one baseline estimate for a respective different input image. The image processing apparatus is further configured to determine one output image of the set of output images as the focused output image.

Abstract: A first aspect of this disclosure relates to a computer-based method of setting an optical focus, comprising the steps of: obtaining a first threshold value for a drift of an optical focus, obtaining a first drift value, wherein it is based on measurements of at least one parameter regarding the focus at different points in time, comparing the first drift value with the first threshold value, outputting the first drift value if it exceeds the first threshold value inadmissibly.
