1. An apparatus that assists in adjusting a focus of an image, the apparatus comprising:

  • an image sensor configured to detect an image; and

    one or more processors programmed to;

    determine that a focus of a focus region of an image is at a first focus level;

    generate a first visual indication of the first focus level;

    generate a second visual indication of the first focus level, the second visual indication being different in shape than the first visual indication;

    generate a graphical representation of the image;

    output, for presentation on a display, the graphical representation together with the first visual indication and the second visual indication so that the first visual indication and the second visual indication are overlaid on the graphical representation and positions of the first visual indication and the second visual indication on the graphical representation depend on a location of the focus region within the image;

    detect a first user adjustment of the focus of the focus region from the first focus level to a second focus level subsequent to the output of the graphical representation together with the first visual indication and the second visual indication; and

    in response detecting the first user adjustment,change the first visual indication from a first color to a second color different from the first color to visually indicate that the focus of the focus region is at the second focus level rather than at the first focus level, andchange the second visual indication to visually indicate that the focus of the focus region is at the second focus level rather than at the first focus level.
