Abstract: In an embodiment a method for measuring ambient light includes successively synchronizing optical signal acquisition phases with extinction phases of a disruptive light source, wherein the disruptive light source periodically provides illumination phases and the extinction phases, accumulating, in each acquisition phase, photo-generated charges by at least one photosensitive pixel comprising a pinned photodiode, wherein an area of the pinned photodiode is less than or equal to 1/10 of an area of the at least one photosensitive pixel, transferring, for each pixel, the accumulated photo-generated charges to a sensing node, converting, for each pixel, the transferred charges to a voltage at a voltage node and converting, for each pixel, the transferred charges to a digital number.

Abstract: Hyperlapse imaging is described. A device may include a camera, an ambient light sensor (ALS), and a data store. The camera is configured to capture images. The ALS is configured to detect associated ambient light properties for at least some of the captured images. The data store is configured to store the captured images and the associated ambient light properties. After a threshold amount, the stored captured images and the associated ambient light properties are processed in bulk to generate a hyperlapse video.
