Abstract
A method and an apparatus for controlling brightness in a portable terminal are provided. The method comprises measuring temperature according to a preset period, extracting a brightness value mapped to the measured temperature from a stored brightness table, and changing a brightness of the portable terminal to correspond to the extracted brightness value.
Claims23
A method for controlling brightness in a portable terminal, the method comprising:
- measuring temperature according to a preset period;
- extracting a brightness value mapped to the measured temperature from a stored brightness table;
- and
- changing a brightness of the portable terminal to correspond to the extracted brightness value,
- wherein the changing of the brightness of the portable terminal comprises:
- checking a current brightness value of a display;
- comparing the current brightness value with the extracted brightness value that is mapped in the stored brightness table to the measured temperature;
- changing a brightness of the display to the extracted brightness value if the current brightness value exceeds the extracted brightness value;
- maintaining the brightness of the display at the current brightness value if the current brightness value is less than the extracted brightness value;
- and
- displaying a state bar indicating an overall brightness divided into a first brightness area indicating selectable brightness as the brightness of the display and a second brightness area indicating non-selectable brightness as the brightness of the display and a process bar indicating currently set brightness of the display.
An apparatus for controlling brightness in a portable terminal, the apparatus comprising:
- a display;
- a temperature sensor for measuring temperature;
- a storage for storing a brightness table which stores a mapping of temperature and brightness;
- and
- a processor that extracts a brightness value mapped to the measured temperature from the brightness table, and that changes the brightness of the display to correspond to the extracted brightness value,
- wherein the processor checks a current brightness value of the display, compares the current brightness value of the display with the extracted brightness value that is mapped in the stored brightness table to the measured temperature, changes a brightness of the display to the extracted brightness value if the current brightness value exceeds the extracted brightness value, and maintains the brightness of the display at the current brightness value if the current brightness value is less than the extracted brightness value, and
- wherein the processor cause the display to display a state bar indicating an overall brightness divided into a first brightness area indicating selectable brightness as the brightness of the display and a second brightness area indicating non-selectable brightness as the brightness of the display and a process bar indicating currently set brightness of the display.
A non-transitory computer-readable storage medium of a portable terminal storing a program for controlling brightness in a portable terminal, the program comprising instructions to cause a computer to:
- measure a temperature according to a preset period;
- extract a brightness value mapped to the measured temperature from a stored brightness table;
- check a current brightness value of a display;
- compare the current brightness value with the extracted brightness value that is mapped in the stored brightness table to the measured temperature;
- change a brightness of the display to the extracted brightness value if the current brightness value exceeds the extracted brightness value;
- maintain the brightness of the display at the current brightness value if the current brightness value is less than the extracted brightness value;
- and
- displaying a state bar indicating an overall brightness divided into a first brightness area indicating selectable brightness as the brightness of the display and a second brightness area indicating non-selectable brightness as the brightness of the display and a process bar indicating currently set brightness of the display.
