ABSTRACT:
The present invention relates to a display apparatus having a large-scaled pixel number and capable of displaying a television image and the like. In the display apparatus, after data included in an effective segment of an input signal have been A/D-converted, the converted digital data are stored into a frame memory. Then, while the stored digital data are read from the frame memory, an enlarging control unit adds the pixel data which can be transmitted within a time period corresponding to the horizontal blanking period and also the vertical blanking period, to the read digital data. The resultant digital data are transferred to a display unit.
