Method for controlling electronic apparatus and electronic apparatus applying the method

Abstract

A method for controlling an electronic apparatus with a display and an input device, which comprises: sensing a tilt angle of the electronic apparatus in a sleep mode, wherein the display is off and the input device is non-active in the sleep mode; activating the input device without turning on the display based on the tilt angle of the electronic apparatus; receiving a user input from the input device while the display is off; and performing a predetermined function based on the user input.

1 . A method for controlling an electronic apparatus with a display and a hardware button provided on a case of the electronic apparatus, comprising:
 sensing a tilt angle of the electronic apparatus in a sleep mode, wherein the display is off and the hardware button is non-active in the sleep mode;   activating the hardware button without turning on the display based on the tilt angle of the electronic apparatus;   receiving a user input from the hardware button while nothing is displayed on the display; and   performing a camera function based on the user input;   wherein the hardware button can receive at least two kinds of user inputs.   
     
     
         2 . The method of  claim 1 , further comprising:
 activating the hardware button without turning on the display after the tilt angle is determined to fall in a predetermined angle range.   
     
     
         3 . The method of  claim 1 , further comprising:
 activating the hardware button without turning on the display for a predetermined period of time immediately after the tilt angle is determined to fall in a predetermined angle range.   
     
     
         4 - 6 . (canceled) 
     
     
         7 . The method of  claim 1 , wherein the step of activating the hardware button without turning on the display is further based on an environment parameter detected by the electronic apparatus. 
     
     
         8 . The method of  claim 1 , further comprising:
 keeping the hardware button active for a predetermined period of time immediately after the display is turned off;   receiving a second user input from the hardware button while the display is off during the predetermined period of time immediately after the display is turned off; and   performing a second predetermined function based on the second user input.   
     
     
         9 . The method of  claim 8 , further comprising:
 performing the second predetermined function with turning on the display based on the second user input.   
     
     
         10 . (canceled) 
     
     
         11 . The method of  claim 1 , further comprising:
 keeping the hardware button active for a predetermined period of time immediately after the display is turned off;   determining if any second user input is received from the hardware button during the predetermined period of time;   entering the sleep mode after the predetermined period of time, after no second user input is received from the hardware button during the predetermined period of time.   
     
     
         12 . An electronic apparatus, comprising:
 a display;   a case;   a hardware button provided on the case, wherein the display is off and the hardware button is non-active in a sleep mode;   a processing module connected to the display, the hardware button, and configured to:   activate the hardware button without turning on the display based on a tilt angle of the electronic apparatus;   receive a user input from the hardware button while nothing is displayed on the display; and   control the electronic apparatus to perform a camera function based on the user input;   wherein the hardware button can receive at least two kinds of user input.   
     
     
         13 . The electronic apparatus of  claim 12 , wherein the processing module is further configured to:
 activate the hardware button without turning on the display after the tilt angle is determined to fall in a predetermined angle range   
     
     
         14 . The electronic apparatus of  claim 12 , wherein the processing module is further configured to:
 activate the hardware button without turning on the display for a predetermined period of time immediately after the tilt angle is determined to fall in a predetermined angle range.   
     
     
         15 - 19 . (canceled) 
     
     
         20 . The electronic apparatus of  claim 12 , wherein the processing module further comprises a main controller and a sub-controller connected to the main controller, wherein the sub-controller is configured to:
 activate the hardware button without turning on the display based on the tilt angle of the electronic apparatus;   receive the user input from the hardware button while the display is off;   activate the main controller to perform the camera function based on the user input.   
     
     
         21 - 23 . (canceled)
