Abstract
A method and apparatus for converting a digital video signal, to a signal having a resolution that matches a display device, by using simple hardware alone. When a digital video signal is input together with a data enable (DE) signal and a dot clock (DCLK) signal, the number of clocks of the DCLK signal generated during an active period of the DE signal is counted and, based on the thus counted number of clocks, the resolution of the input video image is identified; then, based on the resolution thus identified, the pixel density of the input video signal is converted so as to form a video signal having a resolution that matches the display device. Alternatively, the resolution of the input video signal may be identified by counting the number of pulses of the DE signal generated during one vertical synchronization period.
