The disclosure describes the use of image sensors in a variety of different imaging applications. In some implementations, the pixels of an image sensor may be configured (e.g., programmed) with one or more analog filters to sense a variety of things, including, for example: average intensity and color (like a standard camera), 3D depth (like a time of flight or structured light camera), changes and/or motion in an image (like an event based camera), spectral reflectance (like a spectroscopy camera), and many other features of an imaged scene or object. In alternative implementations, digital filtering may be applied to the output of an image sensor to realize one of these applications.
