Abstract

PURPOSE:To give the zoom effect and to perform the display with high resolution, by displaying the entire or a part of the original picture with sampling, in the unit in which the number of the light emitting elements constituting the video elements is less than the number of the video elements constituting the original video signal. CONSTITUTION:In the display unit in which the number of the light emitting elements constituting the matrix panel MP is less than the number of video elements of the original video signal, the timing of the sampling pulse Sc of the clock pulse generating circuit Sc fed to the sampling hold circuit SPH of the AD conversion circuit AD is controlled to set the leading edge of the horizontal direction display by the panel MP of picture specified with the original picture. Moreover, the preset pulse of the horizonal synchronous signal counter H for shift pulse generation of vertical scanning signal is formed. The display leading edge of the panel MP is set by delaying the delay amount of the vertical synchronizing signal separated with the synchronous separation SYS from the original video signal with the scan pulse generating circuit SG.
