Provided is an image input apparatus in which changeover between sensing and transfer of low-resolution images such as moving images and high-resolution images such as still images can be performed smoothly during image sensing and data transfer operations. The apparatus includes an image signal generating circuit for sensing the image of a subject and generating an image signal indicative thereof; a data transfer circuit for transferring the image signal generated by the image signal generating circuit to an external device via a prescribed communications interface, the 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 a control circuit for controlling the data transfer circuit so as to perform image transfer in the first transfer mode in a case where the image signal generating circuit generates a low-resolution image signal and in the second transfer mode in a case where the image signal generating circuit generates a high-resolution image signal.
