    摘要: A photosensor system performs a sensitivity-adjusting reading operation with respect to a subject image, while simultaneously changing the image reading sensitivity stepwise for each of rows of a photosensor array or for specific rows thereof. The dynamic ranges of the lightness data on the read subject image are checked to see how they are distributed in relation to the image reading sensitivities. On the basis of this distribution, an image reading sensitivity that contributes to an optimal image reading state is extracted as an optimal image reading sensitivity.

    摘要: In a photosensor system formed of a photosensor array including a plurality of photosensors arranged in a two dimensional direction, the intervals of the reset pulse, read pulse and pre-charge pulse applied to each row of the photosensor array are respectively set equal to the sum of the reset period, the read period, and the pre-charge period. It follows that even where the read processing time of a single screen is shortened by allowing the processing cycles for the rows to partially overlap with each other, the reset period, the pre-charge period and the read period are prevented from being overlapped in time with each other, making it possible to perform the read operation accurately.

    摘要: This invention reads image data of a subject by performing pre-reading operation while changing the image reading sensitivity at a plurality of stages immediately before the start of normal reading operation of a subject image, calculates the absolute difference value between adjacent pixels of lightness data of the read image data, and sets as an optimal reading sensitivity an image reading sensitivity having a maximum absolute difference value among calculated absolute difference values in a photosensor system having a photosensor array constituted by two-dimensionally arraying a plurality of photosensors, a driver circuit for supplying a drive signal to the photosensors, and a controller for controlling reading operation of a subject image and sensitivity setting. Even when ambient light changes or the characteristics of the photosensor change, an optimal image reading sensitivity can be set in accordance with the changes. Further, even when a position where the subject is placed in the detection area of the photosensor array offsets from a normal position in performing pre-reading operation, and the read image data contains a background pattern together with the subject image, a proper image reading sensitivity can be extracted and set without any influence of the background pattern. An image reading sensitivity setting method having high reliability can be provided.

    摘要: Disclosed is a method for estimating, within a short time, the life of a cable insulating coating material containing an antioxidant in a suitable concentration based on the rate of decrease of the antioxidant and on the critical concentration of the antioxidant at which oxidative degradation rapidly proceeds. The method tests the coating material to examine its life, the coating material including a base polymer, and an antioxidant having a functional group suppressing an oxidative deteriorative reaction of the base polymer. The method includes performing a thermal degradation test on the coating material; determining the degradation levels and degradation rates of the coating material at two or more time points in the thermal degradation test, based on the ratio of the absorbance of the functional group of the antioxidant to the absorbance of the base polymer; and thereby evaluating the life of the coating material.
