1. An apparatus for processing images, the apparatus comprising:

  • an image sensor configured to be worn by a visually impaired user and configured to capture real time images from an environment of the user; and

    at least one processor device configured to;

    initially process at least one image of the captured real time images to identify an object in the environment of the user that is likely to change its state;

    provide a first feedback to the user that indicates a current state of the object;

    after providing the first feedback, determine that the object has left a field of view of the image sensor;

    after determining that the object has left the field of view of the image sensor, provide a second feedback to the user that indicates the object is no longer in the field of view of the image sensor;

    after providing the second feedback, determine that the object has reappeared in the field of view of the image sensor; and

    after determining that the object has reappeared in the field of view of the image sensor, continue to capture images of the object and alert the user with a third feedback after a change in the state of the object occurs, wherein the third feedback indicates a new state of the object,wherein the change of state includes at least one of a change in color, a change in position, and a change in display of information, and the change of state is determined while the object remains in the field of view of the image sensor.
