<p>PURPOSE: A clock provider provides clocks corresponding to different image formats without image deteriorations so that a digital imaging device with built in the clock provider can display both the digital and analog signals. CONSTITUTION: The first and second clock generating units(12,13) generate the first and second clocks in response to the first and second format respectively. From the two clocks, a clock selector(14) select one and a PLL unit outputs the proper format of image signal after modulating phase of the received signal. Then, a video graphic processor(30) outputs display signals with respect to the display format. An analog display processor(40) separates synchronizing signals and transmit them into a deflection circuit(18), then display in the screen.</p> |
