Methods and apparatuses for compressing drive curves for scanning devices and corresponding computer programs are provided. In this case, a drive curve is decomposed into segments. Segments which are not yet present in a library are stored in the library. Moreover, for each segment a pointer to a corresponding segment in the library is stored in a list.

The invention is based on the object of providing a particularly reliable closed-loop control for a scanner. According to various examples, this object is achieved by an analysis of a system deviation in the frequency space. By way of example, an input signal, which is indicative of a time dependence of the system deviation between an ACTUAL pose and a TARGET pose of a deflection unit of the scanner, can be expanded into a multiplicity of error components and a plurality of frequencies. Then, a corresponding correction signal component can be determined for each of the multiplicity of error components. By way of example, such techniques can be used in a laser scanning microscope.

The control unit of a projector drives modulators for the range of brightness of the image data with a first resolution of NN levels, wherein NN is an integer greater than one. The control unit applies a predefined brightness change to the brightness value in accordance with the image data for the image point such that a changed brightness value having a second resolution, which is greater than the first resolution, is calculated, and converts the changed brightness value into the increased brightness value such that it has the first resolution and is greater than a notional comparison value having the first resolution that arises if the predefined brightness change is applied to the brightness value in accordance with the image data, with the result that the control unit drives one of the modulators for a pixel to be boosted with the increased brightness value having the first resolution.
