<P>PROBLEM TO BE SOLVED: To detect a change point deviation of a valid section signal to a receiving unit produced by noise elimination, to cope with the problem of being incapable of appropriate reception of an image data. <P>SOLUTION: A data transmission device includes: a transmitter unit for transmitting an image data, a first valid section signal indicative of a valid or invalid image data and a synchronous signal indicative of a line changeover; and a noise processor unit for receiving the inputs of the image data, the valid section signal and the synchronous signal, and outputting the image data and the synchronous signal, and generating and outputting a second valid section signal obtained by eliminating a noise from the first valid section signal; and a receiver unit for receiving the inputs of the image data, the synchronous signal and the second valid section signal output from the noise processor unit, and acquiring the image data of the valid section by the second valid section signal. The noise processor unit measures a time from a synchronous signal change point to the change point of the second valid section signal, and detects the presence or absence of a deviation of the valid section by a noise mixed into the first valid section signal. <P>COPYRIGHT: (C)2013,JPO&INPIT |
