The invention relates firstly to a method for determining a mechanical deviation on a displacement path of an optical zoom lens (03), in particular on a displacement path of an optical zoom lens (03) of a microscope. The optical zoom lens (03) is arranged in a beam path (01) between an object (19) to be recorded and an electronic image sensor (04). In a first method step, an optical marker is introduced into the beam path (01) at a position of the beam path (01) located between the object (19) to be recorded and the optical zoom lens (03), such that the optical marker passes the optical zoom lens (03) and then is depicted on an image in which a position of the optical marker is detected and determined. This is compared with a reference position of the optical marker in order to determine the mechanical deviation on the displacement path of the optical zoom lens (03). The invention further relates to a method for correction of a displacement error of an image recorded by an electronic image sensor (04) and to an electronic image recording device.

A system and method for obtaining, by an electronic device, a first set of image data recorded during an image capture event and a second set of image data recorded during an image capture event. During the image capture event, a characteristic of an image capture device is changed from a first state to a second state. The first and second sets of image data are recorded by an image capture device having one or more image recording components with one or more image sensor arrays. An image is generated based at least in part on the first and second sets of image data.

Structures for scattering light at multiple wavelengths are disclosed. Scattering elements are fabricated with different geometric dimensions and arrangements, to scatter or focus light at the same focal distance for each wavelength, or at different focal distances according to the desired application. Scattering elements can be circular or elliptical posts, allowing polarization dependent scattering. The elements can have different orientations to scatter light from multiple wavelengths at the desired focal length.
