摘要:
A method for driving a plasma display panel (PDP) to indicate a precise emission image corresponding to pixel data thereon. The method comprises the steps of applying first priming pulses to all of the row electrodes simultaneously to execute a simultaneous priming stage, and then applying a second pulse for reproducing charged particles in the discharge region just before applying a scan pulse for writing pixel data to the pixel cell, thereby writing the pixel data to the respective pixel cells. In other words, the application of the second priming pulse can adjust the amount of charged particles in the discharge region of the pixel cell just before applying the scan pulse to write the pixel data. Therefore, the desired amount of barrier charge corresponding to the contents of the pixel data can be achieved in the pixel cell, thereby obtaining a precise display image on the PDP panel.
摘要:
An imaging device which includes an optical unit passing light from a subject and having an exit pupil position. An image pickup element receives the light from the subject passing through the optical unit, and produces an image signal from the received light. The image signal has corresponding color excitation values. A color compensation mechanism adjusts a ratio of the color excitation values of the image signal produced by the image pickup element by adjusting at least one of the color excitation values in correspondence with the exit pupil position of the optical unit. Further, the imaging device can include an aperture positioned between the optical unit and the image pickup element to limit the amount of light received by the image pickup element from the optical unit. The size of the aperture is adjustable. The color compensation mechanism can then adjust a ratio of the color excitation values of the image signal produced by the image pickup element by adjusting at least one of the color excitation values in correspondence with the size of the aperture.

A digital still camera records image data corresponding to a photographed subject, in frame units on a recording medium, and includes a classification unit to classify the image data corresponding to the photographed subjects into specific groups and a recording control to record image data corresponding to plural frames of the specific groups classified by the classification unit.
摘要:
A camera in which the compressibility of digital image data is controlled by a focus signal. The camera includes an imaging device and a photographic optical system which forms a subject image on the imaging device, the imaging device converting the subject image into electrical signals. A focus detection device is coupled to the photographic optical system and focuses the photographic optical system. The focus detection device also provides a corresponding focus output signal. An analog-to-digital conversion unit receives the electric signals from the imaging device and converts the electric signals into digital signals. A compression unit receives the digital signals from the analog-to-digital conversion unit and the focus output signal from the focus detection device and compresses the digital signals at a compressibility corresponding to the focus output signal.

A microorganism belonging to the genus Pseudomonas; an alkaline lipase produced by the microorganism or its mutants; a method of producing the alkaline lipase; and detergents containing the alkaline lipase as an aid, the alkaline lipase having (1) an operative pH of from 4 to 11.5, and an optimum pH of from 7.0 to 9.5, as measured using triolein emulsion as a substrate; (2) an operative temperature of from 10.degree. to 80.degree. C., and an optimum temperature of from 55.degree. to 65.degree. C., as measured using triolein emulsion as a substrate; (3) a molecular weight of 28,000 .+-.2,000 as measured by electrophoresis using SDS polyacrylamide; (4) isoelectric point of 4.5 .+-.1.5 as measured by isoelectric focusing polyacrylamide gel electrophoresis; and (5) an inhibition of lipase activity by a detergent component of not higher than 50% as measured using sodium linear-alkylbenzenesulfonate as said detergent component.The alkaline lipase has an improved stability against detergent components such as a surfactant and a protease, and can be blended with a detergent together with a protease. The alkaline lipase is less susceptible to inhibition of lipase activity by a detergent component and can increase washing power of detergents.
