  • Publication number: 20100309332
    Abstract: In an imaging apparatus, an imaging unit generates an acquired image of a subject. A luminance information acquirer acquires the subject's luminance information. A detector detects the subject's luminance range on the basis of the acquired luminance information. An imaging controller sets a range of exposure control values having a step that corresponds to a value obtained by multiplying the detected luminance range by a predetermined coefficient k (where 0<k<1), and then uses the imaging unit to take multiple shots (i.e., multiple imagings) set with respectively different exposure control values within the range of exposure control values. An image compositor generates a composite image by compositing image portions extracted from the plurality of images obtained via the multiple shots. When just one shot is taken, the single exposure control value set for the one shot is contained within the range of the exposure control values.

  • Patent number: 7505187
    Abstract: According to the present invention, highly accurate adjustment of the angles and positions of optical elements constituting an optical scanning unit can be easily performed. For a cylindrical lens that makes the light beam for exposing a photoreceptor converge on the surface of the photoreceptor, a frame is provided for holding the cylindrical lens therein. The frame is supported by two support portions for a chassis of the optical scanning unit such that the longitudinal direction of the cylindrical lens becomes parallel to the scanning direction of the photoreceptor. The optical scanning unit is configured such that the angle of the cylindrical lens in the longitudinal direction is adjustable in the sub-scanning direction of the photoreceptor at the support portion on the front side (operational side) of these support portions.

  • Patent number: 7407727
    Abstract: An electrode according to the invention can provide a non-aqueous electrolyte secondary battery having an ability to release a volume expansion at the time of charge and discharge as well as the time of a cycle. The electrode comprises a current collector made of a material which is not alloyed with Li, and a dot pattern 2 of a metallic material able to be alloyed with Li formed on the current collector. At the time of charge, since the volume expansion of each dot 3 is carried out so as to bury adjoining crevices 4 between the dots, a stress generated is released, thereby degradation of an electrode being avoided. Each dot may also be made into porosity.
