Abstract: A selected color component (R, G, B) for each of a plurality of image pixels (32, P) of an image cell (42, C) is encoded to form a corresponding color component (ER, EG, EB) of a corresponding plurality of encoded pixels (40, PE) in one-to-one correspondence with the image pixels (32, P). A bit length of each color component (ER, EG, EB) of an encoded pixel (40, PE) is less than that of a corresponding image pixel (32, P).

Abstract: A supplemental optic system supported by a forward support structure azimuthally hinged from a forward portion of a track of an overhead support system cooperates with a light projector operatively coupled to the track. The track is suspended from a slider operatively coupled to a support post depending from an associated ceiling mount structure. The position of the slider within the track provides for minimizing the torque on the support post as a result of the distribution of weights of the light projector and the supplemental optic system.

Abstract: A relatively higher resolution digitized image organized as a plurality of first kernel arrays, each with a plurality of pixels, is transformed into a corresponding relatively-smaller second kernel array of a relatively-lower-resolution image and an associated set of remaining pixels. Down-sampled pixels of the second kernel array are generated from linear interpolation of original pixels of the first kernel array. Associated interpolation coefficients incorporate perturbations to locations of the down-sampled pixels that are symmetric with respect to centers of the first and second kernel arrays.

Abstract: A relatively higher resolution digitized image (12) organized as a plurality of first kernel arrays (110), each with a plurality of pixels (37), is transformed into a corresponding relatively-smaller second kernel array (124) of a relatively-lower-resolution image (38) and an associated set (116, 118) of remaining pixels (37). Down-sampled pixels of the second kernel array (124) are generated from linear interpolation of original pixels (37) of the first kernel array (110). Associated interpolation coefficients incorporate perturbations to locations of the down-sampled pixels (37?) that are symmetric with respect to centers (128, 130) of the first (110) and second (124) kernel arrays.

Abstract: A pair of optical prisms arranged in a complementary relationship provides for anamorphic magnification and cooperates with a refractive or diffractive cylindrical lens element, the later of which generates an aberration that at least partially compensates an aberration generated by the pair of optical prisms. The refractive or diffractive cylindrical lens element is rotated out of normal with respect to the optic axis of the system so as to provide for reflecting stray light away from the optic axis.
