Abstract

Abstract A CRT image printing apparatus for making a color print from black-and-white images displayed on a black-and-white CRT corresponding to three color monochromatic images of a color image in three color frame sequential exposure system, comprises three color filters for converting the black-and-white images corresponding to three color monochromatic images to which a color photographic paper and a color photographic film are selectively sequentially exposed, and an image signal processor for changing the black-and-white images negative to positive when the color photographic film is selected to be exposed and positive to negative when the color photographic paper is selected to be exposed.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 116 words
A CRT image printing apparatus comprising: means including a black-and-white CRT for displaying black-and-white images corresponding to red, green, and blue monochromatic images of a color image sequentially for the three colors on said black-and-white CRT; means for converting said black-and-white images to three monochromatic images; means for sequentially exposing said converted monochromatic images on a color photographic paper in multiple exposure for making a print; means for sequentially exposing said converted monochromatic images on a color photographic film in multiple exposure for making a slide; means for selectively enabling said two sequential exposing means; and means for inverting said black-and-white images between negative and positive according to said selection of said two sequential exposure means.
Claim 2
Dependent Claim 116 words
A CRT image printing apparatus comprising: means including a black-and-white CRT for displaying black-and-white images corresponding to red, green, and blue monochromatic images of a color image sequentially for the three colors on said black-and-white CRT; means for converting said black-and-white images to three monochromatic images; means for sequentially exposing said converted monochromatic images on a color photographic paper in multiple exposure for making a print; means for sequentially exposing said converted monochromatic images on a color photographic film in multiple exposure for making a slide; means for selectively enabling said two sequential exposing means; and means for inverting said black-and-white images between negative and positive according to said selection of said two sequential exposure means.
Claim 3
Dependent Claim 18 words
An apparatus as defined in claim 1, wherein said converting means comprises red, green, and blue color filters.
Claim 4
Dependent Claim 19 words
An apparatus as defined in claim 1, wherein said black-and-white image is displayed in negative on said displaying means.
Claim 5
Dependent Claim 17 words
An apparatus as defined in claim 1, wherein said inverting means inverts an image negative to positive.
Claim 6
Dependent Claim 23 words
An apparatus as defined in claim 1, wherein said color photographic film exposing means includes means for decreasing the red component of light.
Claim 7
Dependent Claim 25 words
An apparatus as defined in claim 1, wherein said color photographic film exposing comprising at least multiple exposure means, and an automatic film advancing means.
Claim 8
Dependent Claim 25 words
An apparatus as defined in claim 1, wherein said selectively enabling means is a reflection mirror for turning exposure light at about a right angle.
Claim 9
Dependent Claim 21 words
An apparatus as defined in claim 6, wherein converting means comprising a single set of said red, green, and blue filter.
Claim 10
Dependent Claim 38 words
An apparatus as defined in claim 6, wherein said camera unit is detachably mounted on said apparatus and said converting means comprising two set of said red, green, and blue filters one set for each sequential exposure means.
Claim 11
Dependent Claim 40 words
An apparatus as defined in claim 9, further comprising a red light component decreasing means, said red light component decreasing means is a filter placed in front of said camera unit only upon the exposure of said red monochromatic images.
Claim 12
Dependent Claim 32 words
An apparatus as defined in claim 6, wherein said selectively enabling means comprises a driving mechanism for moving said camera unit into and out of said color photographic paper sequential exposure means.
Claim 13
Dependent Claim 149 words
A CRT image printing apparatus which comprising a black-and-white CRT for sequentially displaying black-and-white images color image to be printed; and three color filters of red, green, and blue for converting correspondingly said black-and-white images to three color monochromatic images to which a color photographic paper is exposed sequentially to make a color print, said apparatus comprising: a camera unit with a color photographic film loaded therein; a reflection mirror removably disposed between said black-and-white CRT and said color photographic paper for directing said black-and-white images toward said camera unit; filter means disposed between said reflection mirror and said color photographic film for reducing a red color component of light passing therethrough; and means for changing said black-and-white images displayed on said black-and-white CRT negative to positive when said reflection mirror is placed between said black-and-white CRT and said color photographic paper and positive to negative when removed therebetween.
Claim 14
Dependent Claim 149 words
A CRT image printing apparatus which comprising a black-and-white CRT for sequentially displaying black-and-white images color image to be printed; and three color filters of red, green, and blue for converting correspondingly said black-and-white images to three color monochromatic images to which a color photographic paper is exposed sequentially to make a color print, said apparatus comprising: a camera unit with a color photographic film loaded therein; a reflection mirror removably disposed between said black-and-white CRT and said color photographic paper for directing said black-and-white images toward said camera unit; filter means disposed between said reflection mirror and said color photographic film for reducing a red color component of light passing therethrough; and means for changing said black-and-white images displayed on said black-and-white CRT negative to positive when said reflection mirror is placed between said black-and-white CRT and said color photographic paper and positive to negative when removed therebetween.
Claim 15
Dependent Claim 16 words
