摘要:
Image signals of an original is obtained from a plurality of image sensors and are successively supplied to an output terminal. A switching element is provided for resetting the previous image signal, which adversely causes to produce noises. An image sensor driving device according to the invention is to cancel the noises by the provision of a noise accumulating circuit and a subtracting circuit for subtracting the noises as accumulated in the noise accumulating circuit from the image signal on which the noises are superimposed.

A thin-film type photoelectric conversion device for use in an image input unit of facsimile equipment, a scanner and the like, which uses a thin-film semiconductor as a phoconductive layer to reading not only a monochromatic image but also a color image with high resolution. A photoelectric conversion device having a photoconductive layer disposed between opposing electrodes, in which a surface facing in a direction perpendicular to a direction of film deposition of the photoconductive layer acting as a light-receiving surface.
摘要:
A manuscript reader comprises an amorphous silicon film sandwiched between at least one transparent electrode and a plurality of metal electrodes formed on an insulating substrate. If the reader includes a plurality of sensors, the detection circuitry can vary a comparison threshold level during the course of one scanning operation.
摘要:
A method for producing a target substance by utilizing a microorganism by culturing the microorganism in a medium to produce and accumulate the target substance in the medium and collecting the target substance from the culture is described. The microorganism is a mutant recombinant strain in which maltose assimilation is controlled by reducing or eliminating the interaction between IIAGlc protein of the glucose PTS and a protein involved in non-PTS uptake of maltose.
摘要:
A cosmetic composition includes a boron nitride complex powder in which particles of metal oxide are attached to at least a part of the surface of a base material consisting of boron nitride. The metal oxide is preferably a combination of titanium dioxide, yellow iron oxide, red iron oxide and black iron oxide. Preferred compositions include liquid or powder foundation, lipstick, eye shadow, eye liner and mascara. The cosmetic composition including a cosmetic powder is capable of imparting smoothness to the touch, lively finish with fine texture and natural glow, and adhesion to the skin when applied to the skin.
摘要:
A coryneform bacterium that is modified by using a yggB gene so that L-glutamic acid-producing ability is enhanced as compared to a non-modified strains is cultured in a medium to cause accumulation of L-glutamic acid in the medium or bacterial cells, and L-glutamic acid is collected from the medium or cells.
摘要:
For example, a plurality of elliptical candidate areas that become candidate areas of detecting objects are set in an image, characteristic values such as average values of luminance of the pixels inside and outside the set candidate areas are compared, and a candidate area whose difference of the characteristic values is determined to be the maximum is detected as the area of the detecting object. In addition, central moment of the detecting object is calculated, and the inclination of the detecting object in the image is detected based on the calculated central moment. Further, two specific points such as eyes of the driver included in the detecting object are detected, and the inclination of the detecting object in the image determined by the detected two points is detected.
摘要:
There are provided an image processing method, and an image processing system, an image processing device, and a computer program product capable of detecting a position of a fringe portion of a detecting object such as an outline of a face of a driver with high precision, even when a variation of illuminance occurs locally in a system using, for example, an on-vehicle camera mounted on a vehicle for imaging the face of the driver. Luminance of pixels arranged in a first direction such as a horizontal direction of an image is subjected to quadric differential, and data based on a quadratic differentiation result is accumulated in a second direction such as a vertical direction, and based on an accumulated result, a position in the first direction of the detecting object in the image is detected.
摘要:
A method for producing L-glutamic acid by culturing a coryneform bacterium which has L-glutamic acid producing ability and which has been modified so that expression of the fasR gene is enhanced in a medium to produce and accumulate L-glutamic acid in the medium or cells, and collecting L-glutamic acid from the medium or cells.
