Abstract
A video image transfer device (2) includes transfer means (4) for switchedly transferring to a display device (9) a plurality of video signals acquired from at least one image pickup device (20), assigning means (8) for dividing a refresh rate of the display device (9) into portions and assigning the portions among the plurality of video signals, and transfer control means (5) for controlling the transfer means (4) in such a manner that each of the video signals is transferred to the display device (9) 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 dropping frame and an insufficient resolution of an important video image.

13. A video image transfer device for acquiring, from at least one image pickup device, a plurality of video signals of different imaging areas, and outputting the plurality of video signals to a display device, so that the display device will simultaneously display the video signals as a plurality of video images, the video image transfer device comprising:
-
a transfer section arranged to selectively transfer to the display device the plurality of video signals acquired from at least the one image pickup device; an assigning section arranged to divide a refresh rate of the display device into portions and assign the portions to the plurality of video images; 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 the video image corresponding to each of the video signals; and the assigning section is arranged to alter how much of the refresh rate is assigned to each of the video images. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
