# Method for controlling an image processing stage for processing image data captured by a surveillance camera

## Abstract

A method for controlling an image-processing stage for image data captured by a downward-looking surveillance camera with a field of view greater than 180° includes obtaining image data comprising (i) a first set of pixels depicting a central scene portion below the horizon and (ii) a second set of pixels depicting a peripheral scene portion above the horizon. A ceiling-detection procedure analyzes pixels of the second set to determine whether the image-processing stage should operate in a ceiling operational mode. When the ceiling operational mode is selected, the image-processing stage is configured to process subsequently captured image data—again comprising first and second pixel sets—such that at least one image-processing operation is applied to the first set of pixels and not to the second set of pixels. Selectively disabling processing for peripheral pixels above the horizon reduces artifacts and computational load when a ceiling occupies the peripheral portion.
