PURPOSE: Image display is provided, which is related to a digital image display for converting an analog input video signal to a digital signal, performing signal processes such as pixel conversion on the digital signal, and transmitting the resultant signal to a display unit. CONSTITUTION: Shown in FIG. 1 are an A/D converting block(1) for converting an input analog video signal Sin supplied as a dot train into a digital video signal Sad, a sampling clock generating block(2) for generating a sampling clock Cs, an input signal discriminating block(3) for discriminating the kind of the input analog video signal Sin (kind such as VGA or XGA), a control block(4) for outputting control information Scs and Scd for controlling generation of the sampling clock Cs and a data clock Cd, a signal processing block(5) for performing signal processes such as a pixel converting process on the digital video signal Sad and outputting the processed signal as a digital video signal Sout, a data clock generating block(6) for generating the data clock Cd for specifying the resolution after the pixel converting process, and a display unit(7) such as a liquid crystal panel portion. The operation of the image display is described hereinbelow. First, the input analog video signal Sin is supplied to the A/D converting block(1) and sampled to the digital video signal Sad.
