In a display control device according to this invention, video signals are given in parallel each of a plurality of extracting means via a common bus means. For this reason, each extracting means can selectively extract any of the video signals. Each extracting means extracts a portion of or all of required video signals in correspondence to a display area (an area on the display means defined by a display pattern) to be extracted from each of the video signals. The extracted video signals (concretely real luminance signals, interpolated luminance signals, and color signals) are interpolated in horizontal and vertical directions according to a magnification of the display pattern on the display means. This interpolation is an operation to supplement picture elements corresponding to a number of scanning lines and length of the scanning lines which become short when a specified area of the video signal, which is an original signal, is enlarged. The video signals thus interpolated are given to corresponding display units on the display means, respectively. As a result, video signals can be developed at an optional position on the means with an optional size, and in an optional combination.
