Device and method for Input in digital device

The present invention relates to input apparatus and method for a digital processing device, selecting one or more character information corresponding determined by the senses the movement of the object in the images captured by the camera operation, and calculates a motion vector the motion vector to the character type selection receiving the information reads out the character information corresponding to the character type selection information. When the input command of the displayed character information is input and displays the read character information on the display screen, the input method of a digital processing device for displaying on the display screen is provided with the character information as the input information. According to the invention, the advantage to increase the size of the display screen of the digital processing unit has a possible advantage of the miniaturization of the digital processing apparatus, such as further reduce the thickness of the digital processing unit by not including a separate keypad . Motion, portable terminals, cameras, input, detected
