An apparatus for video signal processing can satisfactorily synthesize images by using field memories. This apparatus comprises a control means (1) for controlling operation for making an image, first and second field memories (22), (23) in which image data are written under the control of the control means (1), and output means (21), (24) for outputting image data alternately read out from the first and second field memories (22), (23) at a field period as a video signal to be displayed in an interlace fashion, wherein a vertical direction coordinate of coordinate data written in the second memory (23) is shifted from a vertical coordinate written in the first field memory (22) by a 1/2 horizontal line.
