On-screen display apparatus and on-screen display method |
摘要 |
In an on screen display apparatus and an on-screen display method, the number of scanning lines of an input signal is detected. In accordance with the result of the detection, a vertical dot number of a character to be displayed is determined and font data is read from a memory device after adjusting a dot number of a blank portion of the font data. Hence, even if the number of the scanning lines changes, the number and positions of characters displayed in one screen remain constant.
