In various exemplary embodiments, optically sensitive devices comprise a plurality of pixel regions. Each pixel region includes an optically sensitive layer over a substrate and has subpixel regions for separate wavebands. A pixel circuit comprises a charge store and a read out circuit for each subpixel region. Circuitry is configured to select a plurality of subpixel elements from different pixels that correspond to the same waveband for simultaneous reading to a shared read out circuit.
