摘要： A portable telephone apparatus with camera is disclosed, in which the interference between the harmonic component generated from the camera and the receiving frequency band for radio communication can be reduced. The apparatus comprises a radio communication circuit for conducting the radio communication with an external device, a clock signal generating circuit capable of controlling the output clock signal frequency, a camera operated with the output clock signal as an operating clock signal and a control circuit. The control circuit, based on the receiving frequency band information acquired from the radio communication circuit, controls the clock signal of the clock signal generating circuit in such a manner that the harmonic components of the clock signal frequency are not superposed on the receiving frequency band for conducting the radio communication.
