Abstract
Disclosed are systems and method for providing feedback to a user. In one embodiment, a system and a method pertain to analyzing levels of focus of discrete portions of an image, evaluating a relative focus of the image portions, and identifying to a user the image portions having the highest level of focus.
Claims17
A method for providing feedback to a camera user, comprising:
- capturing an image in response to a user fully depressing a shutter button of a camera;
- storing the captured image in memory;
- dividing the captured image into discrete portions such that substantially each area of the image pertains to one discrete portion;
- analyzing levels of focus of the discrete portions of the captured image;
- evaluating a relative focus of the discrete portions by comparing the levels of focus of each discrete portion;
- and
- identifying to a user the discrete portions having relatively high levels of focus with a graphical indication presented in a display of the camera without providing any graphical indication for the discrete portions having relatively low levels of focus such that the user can see what areas of the captured image are more in focus, wherein
- displaying the graphical indication comprises at least one dot displayed over a discrete portion in the display.

A method for providing a camera user with feedback as to which portions of an image are most focused, comprising:
- focusing on a viewed scene to form a focused image;
- identifying discrete portions of the focused image such that substantially each area of the image pertains to one discrete portion;
- analyzing a level of focus as to each discrete portion;
- evaluating a relative focus of the discrete portions to determine which are relatively more in focus by comparing the levels of focus of each discrete portion;
- and
- presenting a graphical indication in a camera display that identifies each discrete portion by displaying a grid that identifies the bounds of the discrete portions, the graphical indication further identifying the discrete portions which are relatively more in focus without providing any graphical indication for the discrete portions having relatively low levels of focus.

A camera, comprising:
- a display that is configured to display images;
- a processor that controls operation of the display;
- and
- a memory comprising a focus feedback system that is configured to:
- focus on a viewed scene to form a focused image,
- identify discrete portions of the focused image such that substantially each area of the image pertains to one discrete portion,
- analyze a level of focus as to each discrete portion,
- evaluate a relative focus of the discrete portions to determine which are relatively more in focus by comparing the levels of focus of each discrete portion, and
- present a graphical indication in the display that identifies each discrete portion with a grid that identifies the bounds of the discrete portions, the graphical indication further identifying the discrete portions which are relatively more in focus without providing any graphical indication for the discrete portions having relatively low levels of focus.

- the graphical indication comprises shading displayed over entire discrete portions in the display.
