A communication device is provided which is capable of transmitting pickup images efficiently with high portability, manipulativity, and instantaneous response. A control apparatus starts a communication (such as a radio transmission) operation in a communication apparatus simultaneous with an image pickup operation in an image pickup operation when the operation is initiated by a user in a communication device having the image pickup function. Thereby, the pickup images obtained in the image pickup operation are automatically transmitted to a specified transmission destination via a communication apparatus. Thus, a user can obtain and transmit pickup images to a desired transmission destination simultaneously by simply setting the operating mode of the device to a predetermined mode or the like.
