摘要

A wireless image transferring apparatus includes a free-run transmitter and a free-run receiver. The free-run transmitter includes a marker appending unit for appending a vertical synchronization marker to image data and a nondisplay period adjustment unit for adjusting the length of nondisplay period of image data according to monitoring information supplied, the transmitter transmitting the image data and receiving the monitoring information. The free-run receiver includes a marker extraction unit for extracting the vertical synchronization marker from the image data received and a marker position monitoring unit for monitoring whether the position of a marker in the image data containing the vertical synchronization marker extracted by the marker extraction unit lies within a predetermined range or not and generating the monitoring information containing a synchronization adjustment amount used to expand or contract the nondisplay period of the image data such that the position of a marker lies within the predetermined range if the position of a marker lies outside the predetermined range, the receiver receiving the image data and feeding back the monitoring information to the transmitter.
