<P>PROBLEM TO BE SOLVED: To suppress an influence of image data to an image formation process even when erroneous data acquisition or lack of data occurs. <P>SOLUTION: Provided are: an image data transmission controller 112 periodically transmitting packet data or line data based on an image data obtained from an image signal source 140; and an image data reception controller 121 receiving transmission data transmitted from the image data transmission controller 112. In this case, the image data reception controller 121 determines that the transmission data is valid and obtains the transmission data while a packet data identification code or a line data identification code can be detected periodically. The image data reception controller 121 determines that the transmission data is invalid and discards the transmission data when the identification code can not be detected periodically. Then, the image data reception controller 121 gets into synchronization again to detect the identification code and resumes acquisition of the transmission data. <P>COPYRIGHT: (C)2009,JPO&INPIT |
