Claim Text:
1. A method for image reconstruction, comprising: determining a number of single images to be captured depending on a strength of wavelength-dependent aberration changes of an optical system; capturing a plurality of single images according to the determined number using the optical system, wherein at least one parameter of the optical system is different upon capture of at least two single images; and digitally reconstructing, by a processing device, an image in dependence on the plurality of single images and in dependence on information about optical transfer functions of the optical system upon capture of the plurality of single images; wherein a first single image is captured with a first optical transfer function and a second single image is captured with a second optical transfer function, the second optical transfer function being different from the first optical transfer function; the image being reconstructed in dependence on information about the first optical transfer function and information about the second optical transfer function; and wherein capturing the plurality of single images comprises: changing the at least one parameter upon capture of the single images in dependence on at least one of: spatial frequencies at which a second modulation transfer function, which is a modulus of the second optical transfer function, is smaller than the threshold value.
