Patent ID: 6885379

Claim:
A color code decoded circuit of a 3D display, built into an on-screen display of a circuit of a display, the color code decoded circuit comprising: a plurality of comparators, to compare a 3D video signal with a reference signal according to a sampling signal to obtain a plurality of color code values; a plurality of record buffers, to record the color code values; a register, to temporarily store a readable flag that indicates whether the 3D video signal is being decoded; a first counter, to count a number of a vertical synchronous signal of the 3D video signal, wherein each time when the first counter is counting the number of the vertical synchronous signal, the first counter resets the readable flag; and a second counter, to count a number of a horizontal synchronous signal of the 3D video signal, wherein when the number of the horizontal synchronous signal reaches a predetermined value, the second counter configures the readable flag.
