MULTI-SCREEN IMAGE DISPLAY APPARATUS AND MULTI-SCREEN IMAGE DISPLAY METHOD

摘要

PROBLEM TO BE SOLVED: To display the same frame image without shifting visually by synchronizing one image with another. SOLUTION: A simultaneous timing determination means 111 determines the time when the image update timing on a video transmitter 10 which can be judged to occur at the same time when the image update timing on each display controller 21 to 24 occurs and calculates the time difference. A display managing means 120 calculates a display processing start time on the video transmitter 10 as control information and a display data transmitting means 130 adds the control information to a video data 1 and transmits. Display processing means 221 to 224 receive the video data 1 and perform display to displays 31 to 34 respectively and display processing control means 211 to 214 control display processing of the display processing means 221 to 224 based on the time difference calculated by the simultaneous timing determination means 110 and the received control information.
