摘要:
There is a film image information reading apparatus called a film scanner. This apparatus comprises: a lighting optical system to illuminate a film document; a photoelectric conversion element, such as a CCD to convert the image information of the film document into the electric signal; and an adjusting circuit to adjust the output of the photoelectrical conversion element such that a predetermined density of the film document is output as an output of almost the saturation level of that element. The predetermined density is the color density of the base color of a negative film. The adjusting circuit may control the charge storage period, gain, or output level of the photoelectric conversion element. With this apparatus, the positive image can be easily derived by reversing the negative image without considering the base color of the negative film and the image signal of a high quality can be obtained.

摘要:
An image processing apparatus is capable of reading an original image with an arbitrary image magnification, by projecting an original image onto a linear image sensor through an optical system of a variable image magnification, and moving the original image with respect to the image sensor with a speed corresponding to the selected image magnification of the optical system.

A ladder circuit editing system inputs and edits a sequence program for a program controller in the form of a ladder diagram. The ladder circuit editing system has an unavailable area storing at least one inputted circuit pattern and an available area storing a new circuit pattern, and successively inputs circuit patterns from the available area. The ladder circuit editing system includes a circuit pattern extracting means, a display means, and a copying means. The circuit pattern extracting means compares a circuit element from a circuit pattern stored in the available area with a circuit element from a circuit pattern already stored in the unavailable area, and extracts a circuit pattern containing a circuit element that agrees with a stored one. The display means displays the extracted circuit pattern on an input screen. The copying means copies the extracted circuit pattern into the available area according to an operator's entry.

摘要:
In conventional white balance adjustment, the processing is switched at the boundary of a threshold. When white balance adjustment is done for two regions having values near the threshold and similar color tones, their impressions become greatly different from each other. To prevent this, this invention calculates a white balance adjustment coefficient for each color component forming color image data, corrects the adjustment coefficient so as to be consecutive for each value of the color image data, and performs white balance adjustment based on the corrected adjustment coefficient. In performing a plurality of types of correction processes for image data, it is difficult to execute an optimal combination of correction processes in accordance with an input device. This invention specifies the characteristics of the input device, and controls a combination of correction processes with respect to the image data on the basis of the characteristics, thereby realizing proper correction based on the input device characteristics.

p-Hydroxyphenylglycine..alpha.-phenylethanesulfonate which is useful for the production of optically active p-hydroxyphenylglycine and optically active .alpha.-phenylethanesulfonic acid is disclosed. p-Hydroxyphenylglycine..alpha.-phenylethanesulfonate is produced by either reacting DL-p-hydroxyphenylglycine with optically active .alpha.-phenylethanesulfonic acid or reacting (.+-.)-.alpha.-phentylethanesulfonic acid with optically active p-hydroxyphenylglycine to form two diastereomers of DL-p-hydroxyphenylglycine optically active .alpha.-phenylethanesulfonate or optically active p-hydroxyphenylglycine (.+-.)-.alpha.-phenylethanesulfonate, and isolating one diastereomer according to the difference between solubilities of the diastereomers, optionally, combining selective crystallization of one diastereomer and epimerization of another diastereomer in the case of reaction of DL-p-hydroxyphenylglycine and optically active .alpha.-phenylethanesulfonic acid. This reaction is utilized in the resolution of p-hydroxyphenylglycine or .alpha.-phenylethanesulfonic acid by deacidifying the resulting diastereomer.
