Abstract
A live panning system and method for providing a live representation of a portion of a working area are provided. The system includes an image sensor acquiring an image of the entire working area and a processing unit. The image sensor includes an array of pixels, each providing pixel data of the image, and reads out the pixel data of a number of output pixels from the array to generate a sensor video stream, the output pixels corresponding to a cropping window within the image. The image sensor also includes a windowing module configured to move, in real-time, the cropping window within the image. The processing unit monitors viewing instructions from a user selecting a region of interest within the image corresponding to the portion of the working area, and dynamically communicates the viewing instructions to the windowing module such that the cropping window always encompasses the region of interest.
