摘要： A video signal recording and/or reproduction apparatus in which an analog video signal from the inlet is digitized to form video data, then the video data are stored in a memory means for a time, then the stored video data are read out from the memory means before they are recorded on a recording medium. When reproducing the recorded video data from the recording medium, the reproduced video data are stored in a memory means for a time, then the stored video data are read out from the memory means, then the analog video signal is restored from the read video data, and then the analog video signal is produced at the output of the apparatus. Further, by taking the synchronism of the write and read control signals of different frequency for either of the memory means of the recording and reproducing systems, it is made possible to assure accurate and reliable conversion between the analog and digital forms of the video signals when either in the record or in the reproduction mode.

摘要： An image signal processing apparatus inputs a video signal, delays it by one field using a field memory, multiplies the delayed signal by a value K (K less than 1), adds the output from the multiplication to the input signal and supplies the sum to the field memory. The level of the signal read out from the field memory is compared with a predetermined value, and based on the result of that comparison, the video signal being input is substantially inhibited from being supplied to the adding means. The signal obtained by multiplying the immediately-preceding field signal by k, and the present-field signal, are cyclically added, so that the amplitude can be gradually increased. The comparison inhibits addition of a new field signal when the level of that stored in the field memory has reached a predetermined level.
