映像表示装置。[Claims for Utility Model Registration] Image data is written in an image memory in response to a signal output from a light pen facing a CRT, and the image data is transferred to a CRT.
In the video display device for outputting and displaying the RT, the image data is written in a position corresponding to the output signal of the light pen, and the image data is output and displayed, first and second image memories; the first data,
a write control means for determining which of the second image memories is to be written; and when outputting and displaying the image data written to the first and second image memories, only the image data of the first image memory is output and displayed; or first,
1. A video display device comprising readout control means for determining whether to output both image data from a second image memory at the same time.
