Abstract
This document describes asymmetric camera sensor positioning for enhanced package detection. In aspects, an electronic doorbell has an image sensor that is rotated to a portrait orientation and vertically shifted relative to a lens of a camera, resulting in asymmetric positioning of the image sensor relative to the lens. The lens projects an image circle onto the image sensor and the image sensor has a sensor detection area having upper corners within the image circle and lower corners outside of the image circle to enable capture of an object located in a lower portion of the image circle and proximate to an edge of the image circle. Then, lens distortion correction is performed on a captured image to provide a final image usable to detect the package, which may be located within the image circle but outside of a conventional sensor detection area.
