Abstract: An electronic device receives a first plurality of images of a scene captured by an image sensor of an electronic device, receives an ambient light level proximate to the electronic device, and determines whether the ambient light level is less than a first threshold value. In accordance with a determination that the ambient light level is less than the first threshold value, the electronic device detects motion in the scene based on one or more of the first plurality of images. In accordance with detecting motion in the scene, the electronic device receives a second plurality of images of the scene captured by the image sensor of the electronic device, forms a composite image from two or more of the second plurality of images, and causes the composite image to be presented for display on a user device.

Abstract: A method is executed at a camera for controlling a camera mode. The camera is operated in a night mode in which an IR filter is not interposed between a lens assembly and a sensor array of the camera. While operating in the night mode, the camera receives at the sensor array ambient light that is not filtered by the IR filter, and determines whether the received ambient light is due to a light source other than an IR light source. The camera continues operation of the camera in the night mode when it is determined that the received ambient light is due to an IR light source. In some implementations, the camera switches the operation of the camera from the night mode to a day mode when it is determined the received ambient light is due to a light source other than an IR light source.

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.

Abstract: A system and method that provides adaptive IR illumination for a camera. In some implementations, IR illumination adapts to the objects in a scene being monitored and IR illumination adaptation may be implemented in conjunction with automatic exposure and other exposure adjustment methods. Some implementations include: illuminating a scene using a first IR illumination power; capturing a first image of the scene with a camera; and determining whether a first region of the first image is underexposed or overexposed. When the first region is underexposed, the scene is illuminated at a second power level greater than the first illumination power and a second image is captured. When the first region is overexposed, the scene is illuminated at a third power level that is less than the first illumination power and a third image is captured. The operations are repeated until scene illumination is satisfactory.

Abstract: A method is executed at a camera operating in a night mode in which an IR filter is not interposed between a lens assembly and sensor arrays of the camera. In the night mode, the camera receives ambient light that is not filtered by the IR filter. For each image tile, the camera determines whether the ambient light received at the tile is due to an IR light source or a light source other than an IR light source and generates a respective mode change signal accordingly. A mode change parameter is then determined as a function of a total number of the mode change signals for image tiles of the camera. Based on the mode change parameter, the camera determines whether to continue the operation of the camera in the night mode or switch the operation of the camera from the night mode to a day mode.
