Abstract:
1. An image display apparatus comprising: a frame rate converter having a rate conversion frame memory and configured to store an input video signal in the rate conversion frame memory, then read and output the input video signal at a doubled clock rate; a signal format converter configured to convert a pixel sequence of the video signal output from the frame rate converter and output the converted video signal; a controller configured to output a timing signal for controlling 3D glasses, based on the video signal output from the signal format converter; a 3D glasses controller configured to generate a glasses control signal that, in 3D glasses that transmit light alternately to left and right eyes, switches the transmission of the light to the left and right eyes, based on the video signal output from the signal format converter and the timing signal output from the controller; and a spatial modulator configured to spatially modulate light emitted from a light source, based on the video signal output from the signal format converter; wherein when the input video signal is a 3D video signal, the image display apparatus enables the light that has been modulated in the spatial modulator to be viewed stereoscopically by use of the 3D glasses.
