Abstract
An image display apparatus for displaying a 3D video signal using a liquid crystal device such as an HIPS or LCOS device comprises a frame rate converter (3) that converts the input video signal to a doubled frame rate, a signal format converter (4) that converts the pixel sequence of the video signal, a light source controller (7) that outputs a light source control signal for turning the light source used for image display on and off, and a 3D glasses controller (8) that generates a glasses control signal (c3) for shutters (64R, 64L) that switch the transmission of the light to the right and left eyes of 3D glasses (64). The risk of crosstalk between the right and left images, due to device response speed is reduced, without requiring a large number of frame memories.
