According to some aspects, a method for assisting the adjusting of a focus of an image includes providing a graphical representation of a detected image. The method can also include receiving an indication of a user selection of a region of the image and providing a magnified graphical representation of the selected image region. The method may further include providing a graphical indication of a degree of focus for at least a portion of the selected image region. The graphical indication in some instances is visually correlated with the magnified graphical representation of the selected image region. The size, shape, and/or color of the graphical indication in some instances can be correlated with the degree of focus for at least a portion of the selected image region.

1. An apparatus that assists in adjusting a focus of an image, the apparatus comprising: an image sensor configured to detect an image; andone 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; andin 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. 2. The apparatus of claim 1, wherein the image comprises the focus region and a non-focus region different from the focus region, and at least part of a graphical representation of the focus region is within an interior area defined by the first visual indication. 3. The apparatus of claim 2, wherein the interior area is rectangular. 4. The apparatus of claim 1, wherein the one or more processors is programmed to change of the second visual indication by making one or more intermediate adjustments to the second visual indication corresponding to one or more intermediate focus levels between the first focus level and the second focus level. 5. The apparatus of claim 1, wherein the second focus level is more in focus than the first focus level, and the one or more processors is programmed to change the second visual indication by converging points on the second visual indication with respect to other points on the second visual indication to visually convey an increase in the focus of the focus region. 6. The apparatus of claim 1, wherein the one or more processors is programmed to change the second visual indication by changing a shape of the second visual indication. 7. The apparatus of claim 1, wherein the one or more processors is programmed to change the first and second visual indications in real time with the first user adjustment. 8. The apparatus of claim 1, wherein the second focus level is more in focus than the first focus level, and the second color is green. 9. The apparatus of claim 1, wherein the second visual indication comprises a polygon. 10. The apparatus of claim 1, wherein the second visual indication comprises a plurality of triangles. 11. The apparatus of claim 1, wherein the one or more processors is programmed to determine the focus of the focus region in response to a user selection of the focus region received via a user interface. 12. The apparatus of claim 1, further comprising a camera housing and the display, the camera housing being configured to support the image sensor, the one or more processors, and the display. 13. The apparatus of claim 1, wherein the one or more processors is further programmed to: detect a second user adjustment of the focus of the focus region from the second focus level to the first focus level subsequent to detecting the first user adjustment; andin response to detecting the second user adjustment, change the first visual indication from the second color to the first color to visually indicate that the focus of the focus region is at the first focus level rather than at the second focus level, andchange the second visual indication to visually indicate that the focus of the focus region is at the first focus level rather than at the second focus level. 14. A method on assisting in adjusting a focus of an image, comprising: detecting an image with an image sensor;determining that a focus of a focus region of the image is at a first focus level;generating a first visual indication of the first focus level;generating a second visual indication of the first focus level, the second visual indication being different in shape than the first visual indication;generating a graphical representation of the image;outputting, 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;detecting a first user adjustment of the focus of the focus region from the first focus level to a second focus level subsequent to said outputting the graphical representation together with the first visual indication and the second visual indication; andin response said detecting the first user adjustment, changing 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, andchanging 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. 15. The method of claim 14, wherein the image comprises the focus region and a non-focus region different from the focus region, and at least part of a graphical representation of the focus region is within an interior area defined by the first visual indication. 16. The method of claim 14, wherein said changing the second visual indication comprises making one or more intermediate adjustments to the second visual indication corresponding to one or more intermediate focus levels between the first focus level and the second focus level. 17. The method of claim 14, wherein the second focus level is more in focus than the first focus level, and said changing the second visual indication comprises converging points on the second visual indication with respect to other points on the second visual indication to visually convey an increase in the focus of the focus region. 18. The method of claim 14, wherein the second focus level is more in focus than the first focus level, and the second color is green. 19. The method of claim 14, wherein the second visual indication comprises a plurality of triangles. 20. The method of claim 14, further comprising: detecting a second user adjustment of the focus of the focus region from the second focus level to the first focus level subsequent to said detecting the first user adjustment; andin response to said detecting the second user adjustment, changing the first visual indication from the second color to the first color to visually indicate that the focus of the focus region is at the first focus level rather than at the second focus level, andchanging the second visual indication to visually indicate that the focus of the focus region is at the first focus level rather than at the second focus level.
