Abstract: A signal processing device, on the basis of signals that control voltages to be applied to pixels, a boundary between a first pixel corresponding to a first signal that applies a first voltage and a second pixel adjacent to the first pixel and corresponding to a second signal that applies a second voltage different from the first voltage at least by a predetermined threshold. The first signal is corrected to a third signal that applies a third voltage higher than the first voltage, and the second signal is corrected to a fourth signal that applies a fourth voltage higher than the second voltage. The second voltage is higher than the first voltage, the fourth voltage is higher than the third voltage, and a potential difference between the first voltage and the third voltage is larger than a potential difference between the second voltage and the fourth voltage.

Abstract: In the case where a gray-scale difference ?1 between a pixel 110a and a pixel 110b, a gray-scale difference ?2 between the pixel 110b and a pixel 110c are each larger than a threshold value, and ?1>?2, gray-scale values of the pixels 110a, 110b and 110c are corrected into the gray-scale value of the pixel 110b+?1×(1??), the gray-scale value of the pixel 110c+?2×(1??), and the gray-scale value of the pixel 110c+?2×?, respectively (0??, ??0.5). After the correction, a gray-scale different ?1a between the pixels 110a and 110b, and a gray-scale different ?2a between the pixels 110b and 110c satisfy the following formulas: ?1a>?1, and ?2a>?2, respectively.

Abstract: Included are a driving circuit that divides one field into subfields and applies predetermined voltages to liquid crystal elements of pixels to turn on or off each of the pixels, and a determination unit that determines whether a first pixel to be turned off of the pixels is adjacent to a second pixel to be turned on of the pixels. The driving circuit applies a first voltage to the liquid crystal element corresponding to the first pixel and applies a second voltage higher than the first voltage to the liquid crystal element corresponding to the second pixel, and applies a third voltage higher than the first voltage and lower than the second voltage to the liquid crystal element of the first pixel for which the determination unit has determined that the first pixel is adjacent to the second pixel.

Abstract: An improved method of a conventional antithrombin III activity determination method, which does not require dilution of a sample and can avoid influence of heparin cofactor II is provided. This method is characterized in that the reaction of a sample with thrombin in the presence of heparin is carried out in the presence of more than 0.2 to 0.9M of a salt, while such a reaction is carried out in the presence of 0.2M of a salt in a conventional method.
