An image data receiving apparatus includes: a first receiving section that receives a first signal including serial data according to image data a second receiving section that receives a second signal including serial data that is different from the serial data included in the first signal a first conversion section that converts the serial data included in the first signal into parallel data and outputs the parallel data a second conversion section that converts the serial data included in the second signal into parallel data and outputs the parallel data a bit drift amount detecting section that obtains information indicating a degree of drift of the parallel data outputted from the second conversion section from a predetermined bit pattern and a bit shifting section that shifts the parallel data outputted from the first conversion section according to the information obtained by the bit drift amount detecting section.
