Abstract:
An image signal transmission apparatus, which performs a parallel-serial conversion of parallel image data by use of an image-transmitting-side device, thereafter transmits the image data to an image-receiving-side device via a cable, and then performs a serial-parallel conversion of the received image data by use of the image-receiving-side device,said image-transmitting-side device comprising: a one-phase to two-phase converter circuit for separating the parallel image data, which are to be transmitted, into even and odd data; a first parallel-serial converting circuit; a second parallel-serial converting circuit; means for allowing a user to select, as the resolution mode for the image data to be transmitted, one of a first resolution mode and a second resolution mode that is higher in resolution than the first resolution mode; and switch means for applying the parallel image data, which are to be transmitted, to the first parallel-serial converting circuit when the first resolution mode is selected, and for applying the parallel image data, which are to be transmitted, to the one-phase to two-phase converter circuit when the second resolution mode is selected; wherein when the second resolution mode is selected, the even data obtained by the one-phase to two-phase converter circuit are applied to one of the first and second parallel-serial converting circuits, and the odd data obtained by the one-phase to two-phase converter circuit are applied to the other parallel-serial converting circuit.
