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. A method for indicating a focus of a region of an image, the method comprising: detecting an image using at least one imaging sensor;providing a graphical representation of the image on a display, the graphical representation of the image corresponding to the image;determining, using one or more processors, a degree of focus of a region of the image;generating, using the one or more processors, a first visual indication of the degree of focus of the region and a second visual indication of the degree of focus of the region separate from the first visual indication;providing, on the display, the graphical representation of the image together with the first visual indication and the second visual indication;subsequent to providing on the display the first visual indication and the second visual indication, detecting, using the one or more processors, a user adjustment of focus of the image; andin response to detecting the user adjustment, changing, using the one or more processors, the first visual indication on the display responsive to a change in the degree of focus of the region due to the user adjustment, andchanging, using the one or more processors, the second visual indication on the display differently from the first visual indication responsive to the change in the degree of focus of the region due to the user adjustment. 2. The method of claim 1, wherein said changing the first visual indication on the display comprises changing a size of the first visual indication on the display responsive to the change in the degree of focus of the region due to the user adjustment, and said changing the second visual indication on the display comprises changing a hue of the second visual indication on the display responsive to the change in the degree of focus of the region due to the user adjustment. 3. The method of claim 2, wherein the first visual indication on the display is an outline of a first shape and has an inner area through which at least a first portion of the graphical representation of the region is observable on the display, and the second visual indication on the display is an outline of a second shape different from the first shape and has an inner area through which at least a second portion of the graphical representation of the region is observable on the display. 4. The method of claim 3, wherein a center of the first shape and a center of the second shape coincide on the display with a center of the graphical representation of the region. 5. The method of claim 2, wherein said changing the first visual indication on the display comprises changing the size of the first visual indication and a hue of the first visual indication on the display responsive to the change in the degree of focus of the region due to the user adjustment. 6. The method of claim 1, wherein said changing the first visual indication on the display comprises changing a size of the first visual indication on the display between different discrete sizes in a non-continuous manner responsive to the change in the degree of focus of the region due to the user adjustment, each of the different discrete sizes corresponding to a degree of focus different from the other of the different discrete sizes. 7. The method of claim 6, wherein said changing the size of the first visual indication on the display comprises transitioning the size of the first visual indication on the display from a first size of the different discrete sizes to a second size of the different discrete sizes to a third size of the different discrete sizes, the first size being larger than the second size and the third size, the second size being larger than the third size. 8. The method of claim 7, wherein the first size corresponds to a substantially out-of-focus state, and the third size corresponds to a substantially in-focus state. 9. The method of claim 1, wherein said changing the first visual indication on the display comprises changing a size of the first visual indication on the display responsive to the change in the degree of focus of the region due to the user adjustment by decreasing the size of the first visual indication on the display as the degree of focus of the region increases. 10. The method of claim 1, wherein the first visual indication is shaped on the display as a geometric shape different from the second visual indication. 11. The method of claim 1, wherein said changing the first visual indication on the display comprises changing a hue of the first visual indication on the display responsive to the change in the degree of focus of the region due to the user adjustment. 12. The method of claim 1, wherein said determining, said generating, said providing the graphical representation of the image together with the first visual indication and the second visual indication are performed in response to receiving an indication of a user selection of the region via a user interface. 13. The method of claim 1, further comprising: in response to receiving an indication of a user selection of a part of the region, determining, using the one or more processors, a degree of focus of the part of the region separate from the degree of focus of other parts of the region;generating, using the one or more processors, a third visual indication of the degree of focus of the part of the region; andproviding, on the display, a magnified graphical representation of the part of the region together with the third visual indication. 14. An apparatus that assists in adjusting a focus of an image, comprising: at least one image sensor configured to detect an image; andone or more processors in communication with the at least one image sensor and a display, the one or more processors being configured to: determine a degree of focus of a region of the image;generate a first visual indication of the degree of focus of the region and a second visual indication of the degree of focus of the region separate from the first visual indication;show, on the display, a graphical representation of the image together with the first visual indication and the second visual indication;subsequent to showing the first visual indication and the second visual indication on the display, detect a user adjustment of focus of the image; andin response to detecting the user adjustment, change the first visual indication on the display responsive to a change in the degree of focus of the region due to the user adjustment, andchange the second visual indication on the display differently from the first visual indication responsive to the change in the degree of focus of the region due to the user adjustment. 15.
