<p>PROBLEM TO BE SOLVED: To automatically set optimum input environment, to suppress wasteful power consumption and to improve an input operation when a processor is provided with a plurality of input devices. SOLUTION: A pen touch detection function is stopped (B15 to B18) when a state where pen input does not exist continues for not less than prescribed time and the input operation of upper/lower and push keys is detected at the time of performing a mail processing by the input operation using a touch panel or the upper/lower and push keys. Thus, wasteful power consumption with respect to the touch panel is suppressed by using the upper/lower and push keys and malfunction by pen touch can be prevented. At the time of reproducing music information by the operation of a remote control key, an icon for realizing a touch input operation corresponding to the remote control key is set on a picture (B22) if a pen is in the middle of operation (B19 to B21). Consequently, music information can be reproduced by pen-touching the icon.</p> |
