| Abstract: | By researching the characteristic of laser display,this paper deduced the matrix conversion relation between the primary-color system which uses three laser colors(red:671 nm,green:532 nm, blue:473 nm) and the primary-color system of current TV system. A color gamut conversion circuit between the primary-color system which uses three laser colors and the primary-color system of current TV system was designed utilizing decode module,controlling circuit by FPGA and coding module. A method of color gamut conversion in video color signal utilizing FPGA device and corresponding arithmetic were introduced, and its sub-module and working process were elaborated.The composition diagram, hardware design and software process of the circuit were given, as well as the system was described in detail. |
