Abstract

Abstract A spectrum display device for displaying in colors a spectrum obtained by a scientific instrument such as a mass spectrometer in which video signals for producing two colors are supplied to a color display device such as a CRT, for example, a video signal for producing a red color contains information with respect to a first spectrum and a video signal for producing a blue color contains information with respect to a second spectrum, and therefore a region on a display face where the first and second spectra coincide with each other assumes a magenta color when the video signal for producing the red color and the video signal for producing the blue color are simultaneously supplied to the color display device. Accordingly, this spectrum display device makes it possible to perceive the degree of coincidence between the two spectra by a mixed color and to perceive a difference between the two spectra by the two original colors.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 96 words
A spectrum display device comprising a display surface, and means for displaying on said display surface a first spectrum in a first color and a second spectrum in a second color, respectively, in such a way that the first and second spectra are displayed in superposition with each other to form a composite display in which a mixed color is formed of the first and second colors in the area of said composite display where the first and second spectra are substantially equal to each other in intensity and substantially coincident with each other in position.
Claim 2
Dependent Claim 96 words
A spectrum display device comprising a display surface, and means for displaying on said display surface a first spectrum in a first color and a second spectrum in a second color, respectively, in such a way that the first and second spectra are displayed in superposition with each other to form a composite display in which a mixed color is formed of the first and second colors in the area of said composite display where the first and second spectra are substantially equal to each other in intensity and substantially coincident with each other in position.
Claim 3
Dependent Claim 30 words
A spectrum display device according to claim 1, wherein said first color is one of three primary colors and said second color is another one of said three primary colors.
Claim 4
Dependent Claim 38 words
A spectrum display device according to claim 1, wherein said first color is one of three primary colors and said second color is a mixed color formed of the remaining two primary colors of said three primary colors.
Claim 5
Dependent Claim 43 words
A spectrum display device according to claim 1, wherein said first spectrum is a spectrum of an unknown sample, and wherein said second spectrum is a spectrum which is similar to said spectrum of said unknown sample and is obtained by data retrieval.
Claim 6
Dependent Claim 39 words
A spectrum display device according to claim 1, wherein said first spectrum is a fundamental spectrum of a known substance, and wherein said second spectrum is a spectrum which is obtained by analyzing a substance under a predetermined condition.
Claim 7
Dependent Claim 30 words
A spectrum display device according to claim 1, wherein said first spectrum is a spectrum of an internal standard substance, and said second spectrum is a spectrum of a sample.
Claim 8
Dependent Claim 26 words
A spectrum display device according to claim 1, wherein said first spectrum is a background spectrum, and said second spectrum is a spectrum of a sample.
Claim 9
Independent Claim 124 words
A method for visually indicating the similarities and differences both in intensity and position of the component values of first and second spectra, comprising the steps of: displaying a first spectrum in a first color as a first display pattern of the component values of said first spectrum; and displaying a second spectrum in a second color as a second display pattern of the component values of said second spectrum in such a way that said second display pattern is in overlapping relationship and synchronized in display position to said first display pattern, so as to cause the overlapping display areas of the component values of said first and second spectra to appear in a third color formed of said first and second colors.
Claim 10
Independent Claim 124 words
A method for visually indicating the similarities and differences both in intensity and position of the component values of first and second spectra, comprising the steps of: displaying a first spectrum in a first color as a first display pattern of the component values of said first spectrum; and displaying a second spectrum in a second color as a second display pattern of the component values of said second spectrum in such a way that said second display pattern is in overlapping relationship and synchronized in display position to said first display pattern, so as to cause the overlapping display areas of the component values of said first and second spectra to appear in a third color formed of said first and second colors.
Claim 11
Dependent Claim 28 words
A method according to claim 8, wherein said first color is one of three primary colors and said second color is another one of said three primary colors.
Claim 12
Dependent Claim 38 words
A spectrum display device according to claim 8, wherein said first color is one of three primary colors and said second color is a mixed color formed of the remaining two primary colors of said three primary colors.
Claim 13
Dependent Claim 41 words
A method according to claim 8, wherein said first spectrum is a spectrum of an unknown sample, and wherein said second spectrum is a spectrum which is similar to said spectrum of said unknown sample and is obtained by data retrieval.
Claim 14
Dependent Claim 37 words
A method according to claim 8, wherein said first spectrum is a fundamental spectrum of a known substance, and wherein said second spectrum is a spectrum which is obtained by analyzing a substance under a predetermined condition.
Claim 15
Dependent Claim 28 words
A method according to claim 8, wherein said first spectrum is a spectrum of an internal standard substance, and said second spectrum is a spectrum of a sample.
Claim 16
Dependent Claim 24 words
A method according to claim 8, wherein said first spectrum is a background spectrum, and said second spectrum is a spectrum of a sample.
