摘要： The invention relates to a video signal memory equipment comprising a FIFO memory for storing video data of video signals, and a control unit for controlling writing and reading in the FIFO memory, wherein the control unit receives a horizontal synchronizing signal of video signal in video data writing action, writes a specified number of video data from the beginning of video data of brightness signals of the horizontal scanning period sequentially into the FIFO memory, and reads out the specified number of video data upon every input of horizontal synchronizing signal, in video data reading action, in the written sequence as video data of that horizontal scanning period, thereby storing and producing the video data of video signals, whereby video data of each horizontal scanning period of video signals are continuously written into the FIFO memory by every specified number of pieces from the beginning, and are read out by every specified number of pieces upon every input of horizontal synchronizing signal, and hence the video data of video signals can be read out by dividing in every horizontal scanning period, and therefore the address generating device for dividing the data in every horizontal scanning period is not needed in this video signal memory equipment.
