    摘要: A color-separation prism assembly comprises first, second and third prisms. The first and second prisms have entrance surfaces, exit surfaces, and partially-reflecting surfaces, wherein the entrance surface of the second prism is separated by an air gap from the partially-reflecting surface of the first prism. The third prism has an entrance surface and an exit surface, wherein the entrance surface of the third prism is adjacent to the partially-reflecting surface of the second prism. The first prism has a cut-out serving as a flare-stop stop, and providing relief so as to allow the entrance surface of the third prism to slide across a plane disposed over the cut-out into a volume defined by the cut-out. The plane is formed as an extension of the partially-reflecting surface of the first prism. An optical axis passes through the first, second and third prisms. The optical axis passes at normal angles through the entrance surface of the first prism, and the exit surfaces of the first, second and third prisms. The partially reflecting surfaces each have angles-of-incidence of less than 30° relative to the optical axis.

    摘要: A system, method, and computer readable storage medium generates an audio fingerprint for an input audio clip that is robust to differences in key, instrumentation, and other performance variations. The audio fingerprint comprises a sequence of intervalgrams that represent a melody in an audio clip according pitch intervals between different time points in the audio clip. The fingerprint for an input audio clip can be compared to a set of reference fingerprints in a reference database to determine a matching reference audio clip.

    摘要: An electronic view camera integrates a camera head assembly and laptop computer into a tripod mountable unified structure. The rigid frame, that unifies the camera head and computer, accommodates a choice of laptop type computers from a variety of different manufacturers. The open front, back and side design of the rigid frame permits ready access for electrical connections and for access to removable storage devices, keyboard, and pointing device. The computer LCD acts as a large screen viewfinder for the camera and has the “feel” of a professional type view camera rather than the “feel” of a computer system with a photographic peripheral.

    摘要: A method for controlling the exposure of an active pixel array electronic still camera includes the steps of: integrating photocurrent in each pixel during an integration time period; collecting overflow charge from all pixels in the array during the integration time period; developing an overflow signal as a function of the overflow charge; and terminating the integration time period when the overflow signal exceeds a preset threshold level selected to represent a desired reference exposure level. Apparatus for performing the method of the present invention includes circuitry for integrating photocurrent in each pixel during a integration time period; circuitry for diverting and detecting overflow charge from all pixels in the array during the integration time period; circuitry for developing an overflow signal as a function of the overflow charge; and circuitry for terminating said integration time period when the overflow signal exceeds a preset threshold level selected to represent a desired reference exposure level.

    摘要: A corrector optic is provided, for use in a camera system that includes a thick prism in front of the focal plane. The corrector optic includes preferably two lenses to be aligned on the optical axis of the camera system. When coupled within the camera system, the corrector optic is disposed between the objective lens and the prism. A preferred corrector optic includes a positive lens having a convex surface facing the objective lens and a negative lens having a concave surface facing the prism, such that the lenses together reduce spherical and coma aberrations caused by imaging through the prism. Chromatic aberration is also reduced by choosing the negative lens material to have a higher index of refraction and higher dispersion than those of the positive lens material.
