1. An image input apparatus comprising:

  • image signal generating means for sensing the image of a subject and generating an image signal indicative thereof;

    data transfer means for transferring the image signal generated by said image signal generating means to an external device via a prescribed communications interface, said data transfer means having a first transfer mode in which there can be assured a fixed transfer rate but with no guarantee of data, and a second transfer mode in which data is guaranteed but transfer rate is not; and

    control means for controlling said data transfer means so as to perform image transfer in the first transfer mode in a case where said image signal generating means generates a low-resolution image signal and in the second transfer mode in a case where said image signal generating means generates a high-resolution image signal.
