A cellular phone includes, for the sake of privacy protection, a camera for outputting a pick up image in which an operator is photographed, a touch panel to accept designation of at least a partial region of the pick up image, and a control portion to determine a masked region to mask at least a part of the pick up image based on the accepted region, generate a composite image in which the masked region of the pick up image is converted to another image, and transmit the composite image.
