Abstract
An image control device and method, and image display device, capable of producing an image of high quality by joining a plurality of divided frames with the joint areas made inconspicuous. An index electrode is provided in an over-scan region on the side of the joint area of the right and left divided frames. The index electrode outputs a detection signal in response to an electron beam scanning in the over-scan region. Based on the detection signal, obtained is data on a pixel position in the joint area of the divided frames. Further, based on the data on the pixel position thus obtained, estimated is data on a pixel position in an area other than the joint area of the divided frames. Meanwhile, using data obtained based on the detection signal outputted from the index electrode, control of image data is exerted so that the left and right divided frames are joined properly.
