Abstract:
1. Apparatus for producing electronic video signals representative of color images of a scene, comprising: a sensor having a color filter thereover; a lens system that focuses light from said image onto said color filter and sensor; and means for producing electronic video signals from the output of said sensor; said sensor comprising a sensor array having alternate lines offset by half a pixel spacing, and diagonally coupled pixels on successive lines, and said color filter having repeating R, G, and B patterns offset on successive lines so that R pixels are arranged diagonally, G pixels are arranged diagonally, and B pixels are arranged diagonally; said means for producing electronic video signals from the output of said sensor including a first register to which are input solely R pixels, diagonally offset in alternating directions, for successive vertically adjacent lines of a group of lines, a second register to which are input solely G pixels, diagonally offset in alternating directions, for successive vertically adjacent lines of said group of lines, and a third register to which are input solely B pixels, diagonally offset in alternating directions, for successive vertically adjacent lines of said group of lines.
