Abstract
An image input apparatus includes an image data generating unit, a data transfer unit and a control unit. The image data generating unit generates high resolution image data if the image input apparatus is in a high-resolution image mode, and generates low resolution image data if the image input apparatus is in a low resolution image mode. The data transfer unit tranfers the high resolution image data to an external device in an asynchronous or bulk transfer mode, and transfers the low resolution image data to the external device in an isochronous transfer mode. The control unit changes the low-resolution image mode to the high-resolution image mode, if an instruction for selecting the high-resolution image mode is received from the external device during the transfer of the low resolution image data.
