Solid state video camera having improved chromatic aberration suppression and moire suppression

A solid state video camera comprising:

• an imaging part having:
• a prism for decomposing an optical image into first and second green channels, a red channel, and a blue channel, the prism including first and second green optical outputs respectively corresponding to the first and second green channels, a red optical output corresponding to the red channel, and a blue optical output corresponding to the blue channel;
• first and second green channel solid state imaging devices respectively disposed at the first and second green optical outputs for outputting first and second green video signals corresponding to the respective channels, the first and second green channel imaging devices being mutually offset by one half of a pixel in a horizontal direction with respect to the optical image;
• and
• red and blue channel solid state imaging devices respectively disposed at the red and blue optical outputs for outputting red and blue video signals corresponding to the respective channels, the red and blue channel imaging devices being mutually offset by one half of a pixel in the horizontal direction with respect to the optical image;
• and
• a signal processing part having:
• a white balance circuit for receiving video signals corresponding to the first and second green video signals and the red and blue video signals, for summing the video signals corresponding to the first and second green video signals in a 1:1 ratio, for performing a white balance adjustment on the summed green video signals and the video signals corresponding to the red and blue video signals, and for outputting white balanced red, green, and blue channel signals;
• a first matrix circuit for receiving the white balanced red, green, and blue channel signals and outputting a first luminance signal according to a first matrix ratio determined by a television standard in use;
• a second matrix circuit for receiving the white balanced red, green, and blue channel signals and outputting a second luminance signal according to a second matrix ratio Kr:Kg:Kb where Kr+Kg+Kb=1, Kg is the factor of to the green channel signal and is determined by the television standard, Kr is the factor of the red channel signal and is determined according to the formula Kr=(1=Kg)/2, and Kb is the factor of the blue channel signal and is determined according to the formula Kb=(1-Kg)/2;
• and
• a mixing circuit for receiving and summing luminance signals corresponding to the first and second luminance signals, and outputting a summed luminance signal.
