Still picture transmission equipment

Abstract

Abstract PURPOSE:To prevent the disorder of a received picture by using an internal clock even at the time of receiving picture data. CONSTITUTION:At the time of receiving the picture data from an opponent, a carrier signal S1 is extracted from a received AM signal Sa, and instead of making the extracted signal S1 into a clock and writing the picture data to a memory 41, a frequency-dividing signal S1 from a dividing circuit 84 is made into the clock and the picture data are written to the memory 41. Consequently, even though an instantaneous interruption and a pulse noise are generated in a picture data period T6, the increment of a writing address to the memory 41 can not be suspended. Thus, the dislocation of a displayed picture due to the instantaneous interruption and the pulse noise can be prevented.
