Camera adjustment to avoid blemish over active areas
The patent US12047682B1 describes an innovative apparatus and method designed to enhance the functionality of cameras equipped with Pan, Tilt, and Zoom (PTZ) capabilities. The core of the invention involves an interface that receives images from the camera and transmits instructions to modify its PTZ settings. The logic circuitry within the apparatus is responsible for detecting when a blemish obscures part of the camera's lens and for identifying geographic areas within or around the camera's field of view (FOV) that exhibit high activity, defined as areas with motion detected above a predetermined threshold. The system then adjusts the camera's FOV to ensure that the blemish is repositioned to a less active area, thereby maintaining the visibility of critical regions.
Further detailing the operational aspects, the method includes steps for creating an activity heat map to visualize the surrounding environment and pinpoint areas of high activity. The logic circuitry is programmed to minimize the camera's movement while effectively relocating the blemish to a "cold" area of the heat map, which corresponds to lower activity levels. This approach not only optimizes the camera's performance but also ensures that important surveillance or monitoring tasks are not hindered by obstructions on the lens. The claims emphasize the system's ability to dynamically respond to environmental changes, thereby enhancing the overall utility of PTZ cameras in various applications.
