Abstract:
An image display device, comprising:first clock generating means for generating and outputting a first clock based on input horizontal synchronizing signals corresponding to horizontal lines making up input image signals; second clock generating means for generating and outputting a second clock; storage means configured so as to accumulate image data sampled from said input image signals based on said first clock using said first clock output from said first clock generating means, and read out said accumulated image data using said second clock output from said second clock generating means; control means for outputting control signals for controlling the cycle of output horizontal synchronizing signals at the time of reading out and displaying said accumulated image data from said storage means, according to image size information of said input image signals, cycle information of said input horizontal synchronizing signals, and cycle information of said second clock; and synchronizing signal generating means for outputting said output horizontal synchronizing signals based on said control signals output from said control means.
