Method and apparatus for displaying color images

Claim 1

A method for displaying color images comprising: a signal processing step, wherein the field image signals for each color resolved component of a frame color image signal comprising odd number and even number field images, are connected together in series in a predetermined color sequence as odd number field groups and even number field groups, and changed into a signal having the color components sped up several times, a vertical deflection shift step, wherein said changed signal is output to a black and white image display means having an interlace function to display odd number field images and even number field images alternately by a vertical deflection control on an electron beam of a cathode ray tube, and said vertical deflection control in said black and white image display means is adjusted so that a signal for a characteristic color component of said change signal is shifted by only half the horizontal scanning spacing in a vertical direction, with the signals for the odd number field images and even number field images being shifted in opposite vertical directions, and the shifted signals are scanned on said black and white image display means, so that the odd number and even number field images are displayed at respective established locations on the black and white image display means, a light color changing step, wherein a signal which has been divided up corresponding to the color component signal of said changed signal, is input and the non color light signal displayed on said black and white display means is changed into a light signal having a color component corresponding to the input signal.

Claim 2

A method for displaying color images comprising: a signal processing step, wherein the field image signals for each color resolved component of a frame color image signal comprising odd number and even number field images, are connected together in series in a predetermined color sequence as odd number field groups and even number field groups, and changed into a signal having the color components sped up several times, a vertical deflection shift step, wherein said changed signal is output to a black and white image display means having an interlace function to display odd number field images and even number field images alternately by a vertical deflection control on an electron beam of a cathode ray tube, and said vertical deflection control in said black and white image display means is adjusted so that a signal for a characteristic color component of said change signal is shifted by only half the horizontal scanning spacing in a vertical direction, with the signals for the odd number field images and even number field images being shifted in opposite vertical directions, and the shifted signals are scanned on said black and white image display means, so that the odd number and even number field images are displayed at respective established locations on the black and white image display means, a light color changing step, wherein a signal which has been divided up corresponding to the color component signal of said changed signal, is input and the non color light signal displayed on said black and white display means is changed into a light signal having a color component corresponding to the input signal.

Claim 4

An apparatus for displaying color images comprising: a signal processing means, whereby the field image signals for each color resolved component of a frame color image signal comprising odd number and even number field images, are connected together in series in a predetermined color sequence as odd number field groups and even number field groups, and changed into a signal having the color components sped up several times, a vertical deflection shift means, whereby said changed, signal is output to a black and white image display means having an interlace function to display odd number field images and even number field images alternately by a vertical deflection control on an electron beam of a cathode ray tube, and said vertical deflection control in said black and white image display means is adjusted so that a signal for a characteristic color component of said change signal is shifted by only half the horizontal scanning spacing in a vertical direction, with the signals for the odd number field images and even number field images being shifted in opposite vertical directions, and the shifted signals are scanned on said black and white image display means, so that the odd number and even number field images are displayed at respective established locations on the black and white image display means, a light color changing means, whereby a signal which has been divided up corresponding to the color component signal of said changed signal, is input and the non color light signal displayed on said black and white display means is changed into a light signal having a color component corresponding to the input signal.

Claim 5

An apparatus for displaying color images comprising: a signal processing means, whereby the field image signals for each color resolved component of a frame color image signal comprising odd number and even number field images, are connected together in series in a predetermined color sequence as odd number field groups and even number field groups, and changed into a signal having the color components sped up several times, a vertical deflection shift means, whereby said changed, signal is output to a black and white image display means having an interlace function to display odd number field images and even number field images alternately by a vertical deflection control on an electron beam of a cathode ray tube, and said vertical deflection control in said black and white image display means is adjusted so that a signal for a characteristic color component of said change signal is shifted by only half the horizontal scanning spacing in a vertical direction, with the signals for the odd number field images and even number field images being shifted in opposite vertical directions, and the shifted signals are scanned on said black and white image display means, so that the odd number and even number field images are displayed at respective established locations on the black and white image display means, a light color changing means, whereby a signal which has been divided up corresponding to the color component signal of said changed signal, is input and the non color light signal displayed on said black and white display means is changed into a light signal having a color component corresponding to the input signal.
