ABSTRACT:
An image signal generating device has a Y-memory, an R-Y-memory and a B-Y-memory, in which a luminance signal and R-Y and B-Y color differential signals are stored, respectively. When the luminance signal and the color differential signals are recorded on a magnetic disk, the signals are read out from the memories in such a manner that an upper half of the frame is read in a first order and a lower half of the frame is read in a second order which is the inverse of the first order. The first order corresponds to a direction from the upper side of the frame to the middle portion of the frame. The second order corresponds to a direction from the lower side of the frame to the middle portion of the frame.
