Focus assist system and method
First Claim
Patent Images
1. A method of providing feedback to allow focusing of an image in real time, comprising:
- receiving pixel data representing an image, the image comprising a first region and a second region different from the first region;
determining a degree of focus for the first region using a first set of the pixel data corresponding to the first region and a degree of focus for the second region using a second set of the pixel data corresponding to the second region;
generating a first visual indication of the degree of focus for the first region and a second visual indication of the degree of focus for the second region;
providing on an electronic display the first visual indication superimposed on a graphical representation of the first region together with the second visual indication superimposed on a graphical representation of the second region, the electronic display comprising one or more display screens;
subsequent to providing on the electronic display the first visual indication and the second visual indication, detecting a user adjustment of focus of the image;
in response to detecting the user adjustment, receiving updated pixel data representing the image subsequent to the user adjustment of focus of the image;
determining an updated degree of focus for the first region using a first set of the updated pixel data corresponding to the first region and an updated degree of focus for the second region using a second set of the updated pixel data corresponding to the second region; and
changing the first visual indication on the electronic display responsive to the updated degree of focus for the first region and the second visual indication on the electronic display responsive to the updated degree of focus for the second region.

15. An apparatus for providing feedback to allow focusing of an image in real time, the apparatus comprising:
-
an image sensor; an electronic display comprising one or more display screens; and one or more processors in communication with the image sensor and the electronic display, the one or more processors being configured to; receive, from the image sensor, pixel data representing an image, the image comprising a first region and a second region different from the first region, determine a degree of focus for the first region using a first set of the pixel data corresponding to the first region and a degree of focus for the second region using a second set of the pixel data corresponding to the second region, generate a first visual indication of the degree of focus for the first region and a second visual indication of the degree of focus for the second region, provide on the electronic display the first visual indication superimposed on a graphical representation of the first region together with the second visual indication superimposed on a graphical representation of the second region, subsequent to providing on the electronic display the first visual indication and the second visual indication, detect a user adjustment of focus of the image, in response to detecting the user adjustment, receive, from the image sensor, updated pixel data representing the image subsequent to the user adjustment of focus of the image, determine an updated degree of focus for the first region using a first set of the updated pixel data corresponding to the first region and an updated degree of focus for the second region using a second set of the updated pixel data corresponding to the second region, and change the first visual indication on the electronic display responsive to the updated degree of focus for the first region and the second visual indication on the electronic display responsive to the updated degree of focus for the second region. - View Dependent Claims (16, 17, 18, 19, 20)
