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 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.
