摘要： A particular color is defined in terms of red, green and blue densities thereof. When the densities fall within a predetermined ellipsoid in a three-dimensional chromaticity coordinate system the axes of which respectively represent the red, green and blue densities, the color is defined to be of the particular color. The ellipsoid is represented by the following formula.dS.sup.2 =C.sub.11 dB.sup.2 +2C.sub.12 dB.multidot.dG+C.sub.22 dG.sup.2 +2C.sub.23 dG.multidot.dR+C.sub.33 dR.sup.2 +2C.sub.31 dR.multidot.dBwhereindB=B-BdG=G-GdR=R-RB: blue density of measured pointG: green density of measured pointR: red density of measured pointB: average blue densityG: average green densityR: average red densityRed, green and blue densities of a number of points on a color negative to be printed are measured by a measuring means. The outputs of the measuring means are normalized by a normalizing circuit so that equal level of density signals can be obtained regardless of the gamma value and the sensitivity of the negatives when the same subject matter is photographed under the same conditions. The normalized densities are put into said formula and dS.sup.2 for each of the measured points is calculated by a computing circuit. The calculated dS.sup.2 is compared with a predetermined constant K by a comparator. When the calculated dS.sup.2 is not larger than the constant K, the measured point is determined to be of the particular color.

摘要： Red, green and blue densities of a color negative are measured at a plurality of points thereon. The measured densities are normalized by a normalizing circuit so that the same levels of density signals can be obtained regardless of the gamma value and sensitivity of the negatives when the same subject matter is photographed under the same conditions. The normalized density signals are plotted in a chromaticity coordinate system and examined as to whether or not they fall within a given region defining a polygon in the coordinate system. The coordinate system is a two dimensional coordinate system in which the axes thereof represent the combinations of two color densities among red, green and blue densities. When the level of the normalized signals with respect to a given point falls within the given region defined by the polygon, the point is determined to have the particular color.

摘要： A method is disclosed for controlling the exposure during photographic printing. The transmission density of a negative or original is measured to provide an exposure control signal. In an illustrative embodiment of this invention, the original is divided into a central portion, a peripheral portion, an upper portion, a lower portion, a right-hand portion and a left-hand portion. Means are provided for quantizing a difference in average density between the portions in the negative, which is classified into a plurality of categories in accordance with a logic of combining characteristic values of the negative. The method affords an enhancement of accuracy in exposure control and an enhancement of probability of obtaining prints of good quality.

摘要： Red, green and blue densities of a number of points of a color negative or original are measured. If the measured values of the densities fall within an ellipsoid when plotted in a three dimensional coordinate system or within an ellipse when plotted in two-dimensional coordinate system the axes of which represent the red, green and blue densities or combinations of the three color densities, the measured point is determined to have flesh color. When the negative or original has more than a certain number of points of flesh color, it is determined that the principal subject matter of the negative or original is a human figure and the exposure in a printer is controlled to give a print having a desirable flesh color.

摘要： A stimulable phosphor sheet stored thereon a radiation image is two-dimensionally scanned by a stimulating light beam by projecting the light beam along a main scanning line extending in a main scanning direction and moving one of the stimulable phosphor sheet and the stimulating light beam in a sub-scanning direction relatively to the other so that the stimulable phosphor sheet is exposed to the stimulating light beam along a plurality of main scanning lines arranged in the sub-scanning direction at a predetermined pitch and stimulated emission emitted from the part of the stimulable phosphor sheet exposed to the stimulating light beam is photoelectrically converted to an electric image signal by a photoelectric convertor. The power of the stimulating light beam is controlled depending on the pitch at which the main scanning lines are arranged in the sub-scanning direction.

摘要： An improved method for controlling the quantity of exposure in photographic printing to obtain high-quality prints is disclosed. The method is carried out by photoelectrically detecting a plurality of optical densities from a principal portion of a negative film then discriminating the maximum value and the minimum value of the photoelectrically detected optical densities. The difference between the maximum and minimum values is calculated to achieve a first output, and the first output is non-linearly converted and combined with the maximum or minimum value output to achieve a third output for controlling the quantity of exposure. The method provides satisfactory prints even from those negative films having principal subject density failures or color failures.

摘要： A photomultiplier which detects feeble light emitted by the irradiation of excitation light on an image carrier carrying an image related to a living organism has an integration circuit is DC-coupled with a photomultiplier to convert a current signal output from the photomultiplier, to a voltage signal. The voltage signal converted by the integration circuit is logarithmically compressed with a logarithmic conversion circuit. An offset compensation circuit is provided for reducing an offset voltage that could occur because of charge injection in the integral action of the integration circuit.
