Abstract

The present disclosure provides a system and method of setting a display brightness of a display of an electronic device. One or more images of a user of the electronic device may be captured with a camera of the electronic device. A characteristic of an eye of the user may be detected in the one or more images. A light adaptation state of the user's eye may be determined based on the detected characteristic. The display brightness of the display of the electronic device may be set in view of the determined light adaptation state.

First claim

1 . A method of setting a display brightness of a display of an electronic device, comprising:
capturing one or more images of a user of the electronic device with a camera of the electronic device; detecting a characteristic of an eye of the user in the one or more images; determining a light adaptation state of the user's eye based on the detected characteristic; and setting the display brightness of the display of the electronic device based on the determined light adaptation state.

2 . The method of claim 1 , further comprising illuminating the display during the capturing of the one or more images of the user of the electronic device with the camera.

3 . The method of claim 2 , wherein the illumination of the display comprises illuminating the display at a predetermined brightness suitable for use in a high light intensity environment.

4 . The method of claim 2 , wherein the illumination of the display comprises initially illuminating the display at a low brightness level and increasing the brightness of the display to a predetermined brightness suitable for use in a high light intensity environment.

5 . The method of claim 3 , wherein a plurality of images are captured with the camera and the detected characteristic is a change in size or dilation of a pupil of the user's eye.

6 . The method of claim 2 , wherein the illumination of the display comprises illuminating the display and displaying monochrome red light.

7 . (canceled)

8 . The method of claim 1 , wherein a plurality of images are captured with the camera of the electronic device and the detected characteristic is a change in size or dilation of a pupil of the user's eye.

9 . The method of claim 1 , wherein the detected characteristic is a size or dilation of a pupil of the user's eye.

10 . (canceled)

11 . (canceled)

12 . The method of claim 1 , wherein the camera is an infrared camera and one or more infrared images are captured of the user of the electronic device.

13 . The method of claim 1 , further comprising:
determining that the electronic device is presently located in a low light intensity environment; and in response to the determination that that the electronic device is presently located in the low light intensity environment, performing the capturing of the one or more images of the user with the camera, the detecting of the characteristic of the eye of the user in the one or more images, the determining of the light adaptation state of the user's eye based on the detected characteristic, and the setting of the display brightness of the display in view of the determined light adaptation state.

14 . An electronic device, comprising:
a camera; a display; and control circuitry that executes a display brightness function configured to control a brightness of the display by:
controlling the camera to capture one or more images of a user of the electronic device;
detecting a characteristic of an eye of the user in the one or more images;
determining a light adaptation state of the user's eye based on the detected characteristic; and
setting the display brightness of the display in view of the determined light adaptation state.

15 . The electronic device of claim 14 , wherein the display brightness function is further configured to control the display to illuminate during the capturing of the one or more images of the user of the electronic device with the camera.

16 . The electronic device of claim 15 , wherein the illumination of the display comprises illuminating the display at a predetermined brightness suitable for use in a high light intensity environment.

17 . The electronic device of claim 15 , wherein the illumination of the display comprises initially illuminating the display at a low brightness level and increasing the brightness of the display to a predetermined brightness suitable for use in a high light intensity environment.

18 . The electronic device of claim 16 , wherein the display brightness function is configured to capture a plurality of images with the camera, and the detected characteristic is a change in size or dilation of a pupil of the user's eye.

19 . The electronic device of claim 15 , wherein the illumination of the display comprises illuminating the display and displaying monochrome red light.

20 . (canceled)

21 . The electronic device of claim 14 , wherein the display brightness function is configured to capture a plurality of images with the camera, and the detected characteristic is a change in size or dilation of a pupil of the user's eye.

22 . The electronic device of claim 14 , wherein the detected characteristic is a size or dilation of a pupil of the user's eye.

23 . (canceled)

24 . (canceled)

25 . The electronic device of claim 14 , wherein the camera is an infrared camera and one or more infrared images are captured of the user of the electronic device.

26 . The electronic device of claim 14 , wherein the display brightness function is further configured to:
determine that the electronic device is presently located in a low light intensity environment; and in response to the determination that that the electronic device is presently located in the low light intensity environment, perform the controlling of the camera to capture the one or more images of the user of the electronic device, the detecting of the characteristic of the eye of the user in the one or more images, the determining of the light adaptation state of the user's eye based on the detected characteristic, and the setting of the display brightness of the display in view of the determined light adaptation state.
