Abstract:
1. An image compensation device, a composite video signal in a current frame having a chrominance component and a luminance component, the chrominance component being modulated onto a carrier frequency, the image compensation device comprising: a 3D band pass filter, passing a component of a 3D luminance signal within a frequency range with respect to the carrier frequency of the chrominance component and filtering out the other components of the 3D luminance signal; a 3D notch filter, decreasing a signal intensity of the 3D luminance signal within the frequency range with respect to the carrier frequency of the chrominance component; a 3D notch mixing unit, mixing an output of the 3D notch filter with a 3D compensation signal; a 3D summing unit, summing an output of the 3D band pass filter and an output of the 3D notch mixing unit to output a compensated 3D luminance signal; a non-3D notch filter, decreasing a signal intensity of the a non-3D luminance signal within the frequency range with respect to the carrier frequency of the chrominance component; a non-3D band pass filter, passing a component of the non-3D luminance signal within the frequency range with respect to the carrier frequency of the chrominance component and filtering out the other components of the non-3D luminance signal; a non-3D notch mixing unit, mixing an output of the non-3D notch filter with the 3D compensation signal or mixing the output of the non-3D notch filter with a non-3D compensation signal according to whether an area in the current frame and the area in a next frame are similar and according to whether the area is an edge area, or the non-3D notch mixing unit mixing the output of the non-3D notch filter with the 3D compensation signal or mixing the output of the non-3D notch filter with the non-3D compensation signal according to a number of a plurality of sample points which are defined as edge points in the area; a non-3D band pass mixing unit, mixing an output of the non-3D band pass filter with the output of the 3D band pass filter or directly passing the output of the non-3D band pass filter according to whether the area in the current frame and the area in the next frame are similar and according to whether the area is the edge area, or the non-3D band pass mixing unit mixing the output of the non-3D band pass filter with the output of the 3D band pass filter according to whether a 1D luminance signal and a 2D luminance signal in the area are near the carrier frequency and the area is the edge area; and a non-3D summing unit, summing an output of the non-3D notch mixing unit and an output of the non-3D band pass mixing unit to output a compensated non-3D luminance signal.
