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： 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： Red, green and blue densities of a number of points on a color negative or original are measured and the measured values are plotted in a coordinate system. When the measured values of the densities are contained in a predetermined region of the coordinate system defined as the flesh color region, the measured point is determined to be of flesh color. When the number of points determined to be of flesh color is not less than 13 among 748 points sampled, for instance, the color original is determined to have a subject matter of a human figure. Then, in printing the color negative the exposure is controlled to reproduce a flesh color of desired color balance and density.

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： 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： A surface plasmon sensor comprises a prism, a metal film, which is formed on one surface of the prism and is brought into contact with a sample, and a light source for producing a light beam. An optical system causes the light beam to pass through the prism and to impinge upon an interface between the prism and the metal film such that various different angles of incidence may be obtained with respect to the interface. A photodetector detects an intensity of the light beam, which has been totally reflected from the interface, with respect to each of the various different angles of incidence. An electrode stands facing the metal film with a liquid sample intervening therebetween, and a DC voltage is applied across the electrode and the metal film. A substance contained in the liquid sample is thus analyzed quickly and with a high sensitivity.

摘要： A synchronizing signal generating circuit is incorporated in a digital image storing device. When a plurality of video signals composed of different numbers of scanning lines and issued from television cameras of different types of various diagnostic apparatus are converted from analog to digital signals and stored per frame in an image memory in the digital image storing apparatus, sampling pulses for an A/D converter which are synchronous with the horizontal synchronizing signals of the video signals and field discriminating signals relative to odd-numbered fields and even-numbered fields, among composite synchronizing signals, are generated by using an N-multiplier including an equalizing pulse remover controlled by an F/V converter and a field discriminating circuit with a field discriminating time constant being automatically controlled by the F/V converter. The video signals are stored per frame in the image memory on a real-time basis by utilizing the sampling pulses and the field discriminating signal.
