Abstract

Various disclosed embodiments include methods and systems that automatically adjust camera functions of an electronic device to provide improved image quality by determining whether the electronic device is being operated indoors or outdoors.

First claim

What is claimed is:

1 . A method for improving image quality of an image captured by an electronic device in accordance with an indoor/outdoor status of the electronic device, the electronic device including a first sensor and a second sensor different from the first sensor, the method comprising:
receiving, at the electronic device, sun vector data associated with a position of the sun in the sky; and in response to a first sensor reading received from the first sensor meeting a first threshold and a second sensor reading received from the second sensor meeting a second threshold, automatically adjusting, at the electronic device, one or more camera functions of the electronic device to an outdoor setting.

2 . The method in accordance with claim 1 , further comprising:
determining, at the electronic device, whether the first sensor reading meets the first threshold; and determining, at the electronic device, whether the second sensor reading meets the second threshold.

3 . The method in accordance with claim 2 , wherein:
determining whether the first sensor reading meets the first threshold comprises determining whether the first sensor reading exceeds the first threshold, wherein the first sensor comprises a global positioning system (GPS) sensor and the first sensor reading comprises a received signal strength indicator (RSSI) reading; and determining whether the second sensor reading meets the second threshold comprises determining whether the second sensor reading exceeds the second threshold, wherein the second sensor comprises a light sensor and the second sensor reading comprises a LUX reading.

4 . The method in accordance with claim 3 , further comprising:
determining whether the sun vector data corresponds to the LUX reading; and in response to the sun vector data corresponding to the LUX reading, automatically adjusting the one or more camera functions of the electronic device to the outdoor setting.

5 . The method in accordance with claim 1 , wherein:
determining whether the first sensor reading meets the first threshold comprises determining whether the first sensor reading exceeds the first threshold, wherein the first sensor comprises a global positioning system (GPS) sensor and the first sensor reading comprises a GPS received signal strength indicator (RSSI) reading; and determining whether the second sensor reading meets the second threshold comprises determining whether the second sensor reading is less than the second threshold, wherein the second sensor comprises a WiFi sensor and the second sensor reading comprises a WiFi received signal strength indicator (RSSI) reading.

6 . The method in accordance with claim 1 , wherein:
determining whether the first sensor reading meets the first threshold comprises determining whether the first sensor reading is less than the first threshold, wherein the first sensor comprises a WiFi sensor and the first sensor reading comprises a received signal strength indicator (RSSI) reading; and determining whether the second sensor reading meets the second threshold comprises determining whether the second sensor reading exceeds the second threshold, wherein the second sensor comprises a light sensor and the second sensor reading comprises a LUX reading.

7 . The method in accordance with claim 6 , further comprising:
determining whether the sun vector data corresponds to the LUX reading; and in response to the sun vector data corresponding to the LUX reading, automatically adjusting the one or more camera functions of the electronic device to the outdoor setting.

8 . The method in accordance with claim 4 , further comprising:
in response to the first sensor reading failing to meet the first threshold and the sun vector data failing to correspond to the LUX reading, automatically adjusting the one or more camera functions of the electronic device to an indoor setting.

9 . The method in accordance with claim 5 , further comprising:
in response to the second sensor reading failing to meet the second threshold, automatically adjusting the camera functions of the electronic device to an indoor setting.

10 . The method in accordance with claim 1 , wherein the sun vector data is based at least in part on a time of day and geographic coordinates of the electronic device on the earth's surface.

11 . An apparatus for improving image quality of an image captured by the apparatus in accordance with an indoor/outdoor status of the apparatus, the apparatus including a first sensor and a second sensor different from the first sensor, the apparatus comprising:
a processor; and memory coupled to the processor including instructions that, when executed by the processor, cause the apparatus to:
receive sun vector data associated with a position of the sun in the sky;
determine whether a first sensor reading received from the first sensor meets a first threshold;
determine whether a second sensor reading received from the second sensor meets a second threshold; and
in response to the first sensor reading meeting the first threshold and the second sensor reading meeting the second threshold, automatically adjust one or more camera functions of the apparatus to an outdoor setting.

12 . The apparatus in accordance with claim 11 , further comprising instructions that, when executed by the processor, cause the apparatus to:
determine whether the first sensor reading meets the first threshold by determining whether the first sensor reading exceeds the first threshold, wherein the first sensor comprises a global positioning system (GPS) sensor and the first sensor reading comprises a received signal strength indicator (RSSI) reading; and determine whether the second sensor reading meets the second threshold by determining whether the second sensor reading exceeds the second threshold, wherein the second sensor comprises a light sensor and the second sensor reading comprises a LUX reading.

13 . The apparatus in accordance with claim 12 , further comprising instructions that, when executed by the processor, cause the apparatus to:
determine whether the sun vector data corresponds to the LUX reading; and in response to the sun vector data corresponding to the LUX reading, automatically adjust the one or more camera functions of the electronic device to the outdoor setting.

14 . The method in accordance with claim 11 , further comprising instructions that, when executed by the processor, cause the apparatus to:
determine whether the first sensor reading meets the first threshold by determining whether the first sensor reading exceeds the first threshold, wherein the first sensor comprises a global positioning system (GPS) sensor and the first sensor reading comprises a GPS received signal strength indicator (RSSI) reading; and determine whether the second sensor reading meets the second threshold by determining whether the second sensor reading is less than the second threshold, wherein the second sensor comprises a WiFi sensor and the second sensor reading comprises a WiFi received signal strength indicator (RSSI) reading.

15 . The method in accordance with claim 11 , further comprising instructions that, when executed by the processor, cause the apparatus to:
determine whether the first sensor reading meets the first threshold by determining whether the first sensor reading is less than the first threshold, wherein the first sensor comprises a WiFi sensor and the first sensor reading comprises a received signal strength indicator (RSSI) reading; and determine whether the second sensor reading meets the second threshold by de
