  • Format conversion circuit applied to set-top box and associated method
    Patent number: 10506199
    Abstract: A format conversion circuit applied to a set-top box (STB), which is coupled to a display device, is disclosed. The format conversion circuit includes an electro-optical transfer function (EOTF) circuit, a mapping circuit and an opto-electronic transfer (OEFT) circuit. The EOTF circuit converts an input image signal having a first format to a first optical signal. The mapping circuit, coupled to the EOTF circuit, converts the first optical signal to a second optical signal having a second format, wherein at least one of the first optical signal and the second optical signal is generated according to a maximum luminance of the display device. The OETF circuit, coupled to the mapping circuit, converts the second optical signal to an output image signal.
