11. A camera for an electronic device, comprising:

  • a processor;

    a display in communication with the processor;

    a lens; and

    an image sensor in communication with the processor and in optical communication with the lens, comprising;

    a first pixel including a first photodiode;

    a second pixel including a second photodiode;

    a blooming junction in communication with the first pixel and the second pixel; and

    a blooming voltage source in communication with the blooming junction, wherein the blooming voltage source determines a potential of the blooming junction;

    whereinthe lens transmits light to the image sensor, creating charge within the first photodiode and the second photodiode; and

    the blooming junction selectively receives charge from the first photodiode and the second photodiode to substantially prevent the first photodiode and the second photodiode from exceeding a saturation value.
