Patent number: 5313310Abstract: Disclosed herein is a tonal conversion method of a picture useful upon producing a reproduced picture such as hard or soft reproduced picture from an original picture recorded or otherwise stored on a recording medium. Tonal conversion is conducted in such a way that the pictorial information value (X.sub.n) of a picture element on a camera subject; i.e., real picture corresponding to a desired picture element on the original picture, i.e., medium picture is obtained from a density information value (D.sub.n) relating to the density information of the desired picture or the original picture or the medium picture, and converting the thus-obtained pictorial information value (X.sub.n) into a tone intensity value (y) by using a specific tonal conversion formula.Type: GrantFiled: February 16, 1990Date of Patent: May 17, 1994Assignee: Yamatoya & Co., Ltd.Inventors: Takashi Numakura, Iwao Numakura

Patent number: 5286609Abstract: A negative resist pattern is formed using a resist containing a diazoquinone sensitizer. An imagewise exposed area of a layer of the resist is subjected to heat treatment with a water-containing heating medium in the presence of a carboxyl-inactivating agent. The entire surface of the layer is exposed to radiation. The thus-exposed surface is then treated with an alkaline developer solution. An apparatus suitable for use in the practice of the above process is also disclosed.Type: GrantFiled: January 14, 1992Date of Patent: February 15, 1994Assignee: Yamatoya & Co., Ltd.Inventor: Iwao Numakura

Patent number: 5212518Abstract: Herein disclosed is a tonal conversion method for a faded color original picture useful upon producing a printed picture in a halftone from a faded color photographic original in a continuous tone. As picture information of tonal conversion, unfaded light intensity values (Xn) of a pixel in a faded color photographic original, instead of density information values (D.sub.Fn) of a corresponding pixel of the same, are used. The light intensity values (Xn) may be rationally determined, utilizing an assumption of dye loss and density characteristic curves (S-DCC) of a photographic photosensitive material. The light intensity values (Xn) are then converted into halftone dot area % values by conduction of a specific tonal conversion formula.Type: GrantFiled: April 8, 1992Date of Patent: May 18, 1993Assignee: Yamatoya & Co., Ltd.Inventors: Takashi Numakura, Iwao Numakura

Patent number: 5134494Abstract: Light intensity values as picture information of a color original are obtained by using photographic density characteristic curves of the color-film original, instead of conventional density values. Thus obtained light intensity values are processed by conducting a specific tonal conversion formula (1) to obtain color-separation curves for color (C, M and Y) plates. On the basis of the color-separation curves for the color plates, a range to be entered black is determined, and a color-separation curve for a black (B) plate is set by conducting the same tonal conversion formula (1).Type: GrantFiled: May 23, 1991Date of Patent: July 28, 1992Assignee: Yamatoya & Co., Ltd.Inventors: Takashi Numakura, Iwao Numakura

Patent number: 5014120Abstract: Disclosed herein is a method for processing a first picture to be reproduced on a color picture tube. The value e.sub.ys of luminance signal for a shadow S of a second picture, which has been obtained from a preceding scanning operation, is subtracted from the value e.sub.y of luminance signal for a desired pixel P out of video signals received, thereby determining the value e.sub.p of a base luminance signal. Luminance signal values e.sub.s and e.sub.h are set respectively for a shadow S and a highlight H among pixels of the first picture to be reproduced on the color picture tube. The value e.sub.q of a luminance signal for a pixel Q, which corresponds to the pixel P and is to be reproduced, is determined from the signal values e.sub.p, e.sub.s and e.sub.h in accordance with a particular correction formula. The luminance of each pixel, which is to be reproduced on the color picture tube, is adjusted in accordance with the value e.sub.q of the corresponding luminance signal thus determined.Type: GrantFiled: July 10, 1989Date of Patent: May 7, 1991Assignee: Yamatoya & Co., Ltd.Inventors: Takashi Numakura, Iwao Numakura
