Color video camera method and system

PATENT STATUS: GrantedA method for generating interlaced video signals representative of color images of a scene includes the following steps: deriving a progressively scanned luminance signal representative of the scene at a first frame rate; deriving interlaced scanned color component signals and a color-derived luminance component representative of the scene; high pass filtering and scan converting the luminance signal to obtain an interlaced detail luminance component; low pass filtering the interlaced color component signals and color-derived luminance component to obtain interlaced chrominance output signals and an interlaced low pass luminancecomponent; and combining the detail luminance component and the low pass luminance component to obtain an interlaced luminance output signal.
