A video image transfer device includes a transfer section arranged to selectively transfer to a display device a plurality of video signals acquired from at least one image pickup device, an assigning section arranged to divide a refresh rate of the display device into portions and assign the portions among the plurality of video signals, and a transfer controller arranged to control the transfer section in such a manner that each of the video signals is transferred to the display device at a timing according to the portion of the refresh rate assigned to each of the video signals. This makes it possible to prevent a dropped frame and an insufficient resolution of an important video image.
