Terminal apparatus and method of controlling the same
First Claim
1. A terminal apparatus, comprising:
- a touch panel;
an illuminance sensor provided adjacent to the touch panel;
a proximity sensor provided adjacent to the illuminance sensor, the proximity sensor detecting a presence of an object approaching the terminal apparatus;
a processor; and
memory storing instructions for causing the processor to execute;
performing an automatic light modulation of the touch panel;
determining whether or not an illuminance detected by the illuminance sensor varies by a predetermined amount; and
determining whether or not an operation of the touch panel occurs in a predetermined area in a vicinity of the illuminance sensor,wherein after the processor determines that the illuminance detected by the illuminance sensor decreases by the predetermined amount, the processor suspends the automatic light modulation of the touch panel when the processor determines that the operation of the touch panel occurs before a first time elapses and when the processor determines that the operation of the touch panel does not occur before the first time elapses and the proximity sensor detects a presence of an object approaching to the terminal apparatus before a second time elapses after the first time elapses,the processor restarts the suspended automatic light modulation of the touch panel when the proximity sensor does not detect the presence of the object, andthe processor suspends the proximity sensor when the proximity sensor does not detect the presence of the object before the second time elapses.

Abstract
A terminal apparatus includes a light modulation unit to perform an automatic light modulation of a touch panel, an illuminance sensor, a proximity sensor, an illuminance determination unit to determine whether or not an illuminance detected by the illuminance sensor varies, and an operation determination unit to determine whether or not an operation of the touch panel occurs near the illuminance sensor, wherein the light modulation unit suspends the automatic light modulation when the operation of the touch panel occurs before a first time elapses after the detected illuminance decreases, and the light modulation unit suspends the automatic light modulation when the operation determination unit determines that the operation of the touch panel does not occur before the first time elapses after that the detected illuminance decreases and then the proximity sensor detects an object before a second time elapses.
