Abstract
An image display in which occurrence of beat noise can be suppressed without adding noise to an image in a pixel converting process is provided. The frequency of a data clock is preset to a value at which beat noise is not apt to occur (a value such that one of the dot clock frequency of the input analog video signal and the frequency of the data clock is not equal to or close to an integral multiple of the other) for each kind of the input analog video signal and is stored as a frequency correspondence list in a memory MM. In accordance with the kind of the input analog video signal, a control block selects the set frequency of the data clock and allows a data clock generating block to generate a data clock C . Consequently, at the time of a pixel converting process performed by a signal processing block without adding noise to an image, occurrence of beat noise is suppressed.
