摘要： Rotational force of a driving motor is transferred to a photosensitive drum via a planetary-rolle reduction device, so that the photosensitive drum is rotated. A speed detector set on the shaft of the photosensitive drum detects the rotational speed of the photosensitive drum. In accordance with the detected rotational speed of the photosensitive drum, the rotational speed of the driving motor is adjusted so that the photosensitive drum is rotated at a constant speed.

摘要： The present invention provides an image capturing apparatus capable of realizing both improved operability and higher picture quality. In the case where a sports mode which is mainly selected when the subject is a moving subject is set, at the time of image capturing, by electrically connecting a first terminal and a second terminal of a switch to each other to set a state where a base current of a transistor does not flow, a substrate voltage is not switched. On the other hand, in the case where the normal image capturing mode is set which is mainly selected when the subject is stationary, the first terminal and a third terminal of the switch are electrically connected to each other, and a signal is supplied to the base side of the transistor through a resistor, thereby setting so that an emitter current of the transistor flows and switching the substrate voltage.

摘要： An oblique projection optical system for leading rays of light from a display surface on which an image is displayed to a projection surface in such a way that the ray of light from the center of the display surface is obliquely incident on the projection surface in order to project a magnified image of the image displayed on the display surface onto the projection surface includes a plurality of reflecting surfaces having a power. At least two of the reflecting surfaces have a free-form curved surface, and, of all the reflecting surfaces, the one closest to the projection surface has a negative power and at least one of the other has a positive power. Alternatively, in a rear projection optical system having a projection optical system for projecting an image displayed on a panel display surface onto a screen surface, the projection optical system includes at least four curved-surface reflecting mirrors.

摘要： An optical element manufacturing method has a preparation step of preparing a lower mold having a lower mold surface for forming an optical function surface of an optical element to be manufactured and an upper mold having an upper mold surface for forming another optical function surface of the optical element, said lower mold having an outer shape restricting surface for the optical element or being combined with a member having the outer shape restricting surface, said upper mold being opposed to the lower mold; a reference surface formation step of forming a positioning reference surface on a rim of the optical element by heating the outer shape restricting surface of the lower mold or combined with the lower mold and the lower mold surface and dropping molten glass onto the lower mold surface so as to collide with the lower mold surface and spread to be in contact with the outer shape restricting surface; a pressing step of forming the two opposed optical function surfaces of the optical element by, after the formation of the reference surface, opposing the lower mold and the upper mold that is heated and bringing them relatively close to each other while the glass is still at a temperature at which it is deformable by pressing, and pressing the glass; and an element taking out step of, after the pressing step, releasing the glass from the pressing by the upper and the lower molds and taking out the molded optical element. A temperature of the outer shape restricting surface in the reference surface formation step and the pressing step is higher than a temperature which is a difference when 100null C. is subtracted from a glass transition temperature (null C.) of the glass.

摘要： An optical illumination apparatus has a polarization conversion device for converting light from a light source into light polarized uniformly in a predetermined manner and an optical integrator system for illuminating a display panel with the light polarized in the predetermined manner. The polarization conversion device splits the light from the light source into a first light beam and a second light beam in such a way that the first and second light beams are polarized in different manners, and then converts one of the first and second light beams into light polarized in the identical manner as the other light beam. Moreover, the first and second light beams pass through an identical lens cell of a first lens array of the optical integrator system and are imaged on an identical lens cell of a second lens array of the optical integrator system.

摘要： In an image-processing employing a dither matrix a basic dither pattern is formed of a set of a plurality of basic patterns each including a plurality of pixels. In a single basic pattern a single pixel is assigned 1 serving as a number indicating an order followed to illuminate a dot in the dither matrix. When basic dither patterns are arranged longitudinally and laterally a location remotest from any pixel assigned a number is selected and a pixel at that location is assigned a subsequent number. This series of operations is repeated. When there is no basic pattern that is not assigned a number, in basic pattern a number indicating an order followed to illuminate a dot is assigned to allow the dither matrix to a dither matrix of dot convergence type. Thus a dither matrix allowing an image processing apparatus to satisfactorily reproduce an image can be created.
摘要翻译：在采用抖动矩阵的图像处理中，基本的抖动图案由包括多个像素的多个基本图案的集合形成。在单个基本模式中，单个像素被分配为1，其用作指示在抖动矩阵中照亮点的顺序的数字。当基本的抖动图案被纵向和横向布置时，选择距离分配了数字的任何像素最远的位置，并且为该位置处的像素分配后续数字。这一系列的操作重复。当没有没有分配号码的基本图案时，以基本图案表示指示点亮点的顺序的数字被分配以允许抖动矩阵成为点收敛类型的抖动矩阵。因此，可以创建允许图像处理装置令人满意地再现图像的抖动矩阵。

摘要： A simple, compact optical system is provided that includes a transmissive optical element and a HOE but that nevertheless does not require an extra optical element for the correction of chromatic aberration. The HOE is designed to have diffractive efficiency for each of R, G, and B light beams and have different focal lengths for those light beams so as to correct the longitudinal chromatic aberration produced by a rectangular parallelepiped prism. This eliminates the need for an extra means for correcting the chromatic aberration produced by the prism. The HOE may be designed to exhibit different angles of diffraction for the R, G, and B light beams so as to correct the chromatic aberration produced perpendicularly to the optical axis by a wedge-shaped prism.
