As for the graphics data receiving device, the 1st reception section which receives the 1st signal which includes the serial data which responds to the graphics data and the serial data which is included in the 1st signal the 2nd reception section which receives the 2nd signal which includes the serial data which differs and, converting the serial data which is included in the 1st signal to the parallel data, the 1st converter which it outputs and, converting the serial data which is included in the 2nd signal to the parallel data, the 2nd converter which it outputs and, the parallel data which is output from the 2nd converter which slipping vis-a-vis specified bit patternThe bit shift section which shifts the parallel data which is output from the 1st converter according to the information which is obtained whether it is, by the bit gap quantitative sensing station and the bit gap quantitative sensing station which acquire the information which is shown, and, it possesses.画像データ受信装置は、画像データに応じたシリアルデータを含む第1の信号を受信する第1の受信部と、第1の信号に含まれるシリアルデータとは異なるシリアルデータを含む第2の信号を受信する第2の受信部と、第1の信号に含まれるシリアルデータをパラレルデータに変換して出力する第1の変換部と、第2の信号に含まれるシリアルデータをパラレルデータに変換して出力する第2の変換部と、第2の変換部から出力されるパラレルデータが所定のビットパターンに対してどの程度ずれているかを示す情報を取得するビットずれ量検出部と、ビットずれ量検出部により得られた情報に応じ、第1の変換部から出力されるパラレルデータをシフトするビットシフト部と、を有する。
