摘要:
There is disclosed a digital camera in which an aperture value is regulated between the open aperture value and a predetermined aperture value during acquisition of a movie image. The predetermined aperture value can be determined based on a range of a luminous flux for use in focal detection. The predetermined aperture value can be set, for example, such that the range between the open aperture value and the predetermined aperture value is suitable for a focal detecting operation.

A digital camera is disclosed which has a first recording medium for recording captured images and a second recording medium, different from the first recording medium, for recording images obtained after editing the captured images. Since the edited images are recorded on the second recording medium, it is easy to sort out a desired image.

According to one aspect of the invention, there is provided a sensor device which is capable of detecting a state of a movable stage using an easily manufacturable reference grating and capable of improving the accuracy of detection. The sensor device comprises a reference grating which has a configuration that is varied periodically in a two-dimensional direction. A light source emits light to the reference grating. A spectral unit has a plurality of openings to convert the light emitted by the light source into a plurality of light beams through the plurality of openings. A detector unit has a photodetector to receive collectively reflected light beams reflected by the reference grating. The detector unit is provided to detect a state of a movable body relative to the reference grating based on a change of the reflected light beams received by the photodetector.

A focal-length adjusting unit for photographing apparatuses includes a distance-measuring means for detecting the amount of defocus to an object by using a light beam of the object passing through a photographing optical system; at least two optical elements located in an optical path for distance measurement, deflecting incident light from the object to introduce the light into an image sensor or a distance-measuring sensor; a variable optical-property element constituting at least one of the optical elements, capable of changing the deflection of light in accordance with an applied voltage or an applied current; and a voltage applying means or a current applying means for applying a voltage or a current in accordance with the distance-measuring output of the distance-measuring means. In this case, before a distance measurement is made by the distance-measuring means, the function of light deflection of the variable optical-property element is set to a predetermined value.

In the thermal cracking of or heating of hydrocarbons, for example naphtha, a carbonization reaction incidentally takes place due to the fact that Ni, Fe and Co contained in, for example, the conduits of the thermal cracking apparatus have a catalytically carbonizing action. The aim of the present invention is to effectively suppress carbon deposition promoted by these elements, to provide for the incorporation of an inhibitor element, e.g. Li, Na, Ba, Be, Ca, Mg or their oxides, into the heat-resistant alloy, and to form on the surface of this alloy a carbon deposition suppressing layer which comprises an inhibitor element.

An imaging device comprising an imaging section for repeatedly forming subject images at a set period, while performing a bulb exposure operation, and outputting image data; an adding processing section for performing adding processing of the image data and previously output image data; an added image storage section for sequentially storing a plurality of added images that have been determined by the adding processing section; and a selection section for selecting any of the plurality of added images that have been stored in the added image storage section, after completion of the bulb exposure operation.
摘要:
A method for driving a spatial light modulator includes setting a plurality of mirror elements in a first region into a state of phase 0, setting a plurality of optical elements in a second region adjacent in a Y-direction to the first region into a state of phase π, and setting auxiliary pattern elements consisting of a plurality of mirror elements arranged at a pitch P over a resolution limit of a projection optical system in an X-direction in a boundary region extending in the X-direction between the first region and the second region, into the state of phase π. In projecting a pattern onto an object with use of the spatial light modulator having the array of optical elements, the pattern can be formed in position accuracy or shape accuracy finer than the width of images of the optical elements.
