1. An electronic device with an automatic brightness adjustment feature, the device comprising:
- a display unit;
a storage unit;
a light sensor to detect variation of environmental light intensity surrounding the electronic device;
an image capture unit to capture at least one image of a region of at least one pupil of an eye of a user positioned in front of the electronic device, and execute a deep color filter to process the captured image when the user wears sun glasses;
an analysis module to detect the region of the pupil from the captured image by performing a skin-color algorithm, and detect whether a diameter of the pupil from the captured image is different compared to a prior calculated diameter of the pupil saved in the storage unit;
an adjustment module to adjust brightness of the display unit in response to the detected variation of environmental light intensity and the detected difference of diameter of the at least one pupil; and
at least one processor to execute the analysis module and the adjustment module.

Abstract
A electronic device and method regulates a display brightness of the electronic device. The electronic device can create relationships between the external environment brightness of the electronic device and the brightness of the display of the electronic device. Furthermore, the electronic device can regulate the brightness of the display, according to user'"'"'s expression due to the former regulation. The operations of creating relationships and regulating the brightness can be expediently implemented, and faults of the operations can be avoided, by utilizing the electronic device.
