Abstract
An aerial camera instrument configured to acquire high-resolution aerial images from a target area. The aerial camera instrument comprises (i) an imaging sensor having an electronic global shutter functionality, (ii) an external shutter component, and (iii) a coupling functionality configured to synchronize the electronic global shutter functionality and the external shutter component.

An aerial camera instrument configured to acquire high-resolution aerial images from a target area, the aerial camera instrument comprising:
- an imaging sensor, wherein the imaging sensor:
- comprises an electronic global shutter functionality providing for each pixel a simultaneous start and stop for an integration phase corresponding to capturing light and converting it into pixel-resolved electronic signals, and
- exhibits a readout phase corresponding to transforming the pixel-resolved electronic signals into digital image data,
- an external dispersive component being configured to provide an open state and a closed state, wherein:
- the open state provides light transmission towards the imaging sensor, and
- the closed state provides reduced, in particular at least locally reduced, light transmission towards the imaging sensor as compared to the open state,
- a coupling functionality configured to provide a settable coupling of the electronic shutter functionality and the external dispersive component, wherein the settable coupling provides for different activation settings of the electronic shutter functionality and the external dispersive component relative to each other.
