A digital camera system configurable to operate in a low-resolution refocusable mode and a high-resolution non-refocusable mode comprising: a camera body; an image sensor mounted in the camera body having a plurality of sensor pixels for capturing a digital image; an imaging lens for forming an image of a scene onto an image plane, the imaging lens having an aperture; and an adaptor that can be inserted between the imaging lens and the image sensor to provide the low-resolution refocusable mode and can be removed to provide the high-resolution non-refocusable mode, the adaptor including a microlens array with a plurality of microlenses; wherein when the adaptor is inserted to provide the low-resolution refocusable mode, the microlens array is positioned between the imaging lens and the image sensor.

A lenticular media (10) has an encoded portion (12) adjoining a main portion (14). The encoded portion (12) is located to provide alignment and registration for precisely determining the location of lenticules (16) in the main portion (14).

Lenticular media having spatially encoded portions

An apparatus (10) for measuring the location of lenticules (24) in lenticular media (14) having an encoded portion (14) located adjacent to the lenticules (24) comprises a light source (18) for illuminating the encoded portion (12). A sensor (20) is provided for receiving light referred and then transmitted by the encoded portion (12) that corresponds to the precise location of the encoded portion (12). Moreover, a processing means connecting the sensor (20) is provided for analyzing the signal so as to enable a precise location of the lenticules (24).

An image processor based system and method for recognizing predefined-types of coating density imperfections in a web, specifically continuous type or streak imperfections. Continuous type imperfections are recognized in a continuous web moved at a certain rate through an imaging region illuminated by a stripe of substantially constant illumination. A time-delay integrating CCD camera is focused on the illuminated imaging region. The TDI CCD camera comprises an array of N rows of M light sensitive CCD elements each imaged on a fixed discrete pixel-related image area of the illuminated imaging region. The charge levels accumulated in the CCD elements of each row are shifted to the succeeding row or CCD elements and summed with the charge levels therein at a line shift clock frequency that ensures that an asynchronous relationship exists with respect to the incremental movement of the web. During the clock cycle of the N rows, the corresponding pixel areas of the illuminated web shift asynchronously or creep through the discrete pixel-related image areas. The accumulated pixel charge values derived from the pixel-related image areas of the illuminated region of said moving web emphasize imaging of longitudinal streak imperfections in the web due to the asynchronous movement the web.

An image processor based system and method are provided for recognizing predefined-types of coating density imperfections in a web. Specific imperfection-types to be analyzed include continuous-type, as well as point-type, anomalies. Continuous-type imperfections are recognized in a moving continuous web through the accumulation and integration of density data on the web passing through a system imaging area. Depending upon the type of imperfection to be imaged, the light source provides either constant illumination or strobed illumination of the moving coated web. For most types of imperfections, transmissive illumination of the web is used, however, for point-type anomalies reflective illumination is possible, particularly if the web is static. A machine vision image processor contains predefined lookup tables which allow adaptive control of web illumination within the imaging area. An integrating sphere is used to provide for uniform web illumination. Corresponding machine vision based imperfection recognition processing routines are also described.

Apparatus for splicing together opposite ends of a sheet of material, such as a photoconductor, to form an endless loop includes a generally cylindrical drum on which the sheet material is wrapped. The drum has edge portions that can be adjusted relative to each other to vary the circumference of the drum, and the sheet is wrapped on the drum with opposite ends of the sheet being in overlapping relationship adjacent the edges of the drum. The drum edges are adjusted relative to each other while a sensor detects the relationship between perforations or other identifiable features on the sheet. When a predetermined relationship is obtained, the opposite ends of the sheet are bonded together to form an endless loop. The apparatus produces a loop that is cylindrical in shape with the pitch of the perforations across the splice being equal to the pitch of the perforations in other portions of the loop.
