  • Patent number: 5897232
    Abstract: A photographic camera (10) includes a film supply chamber (14); a film takeup chamber (16) and a film exposure gate (18) positioned between the chambers. The gate defines a maximum exposed image width (W) in a direction of film travel between the chambers and a maximum exposed image height (H) in a direction transverse to the direction of film travel. A plurality of mask members (24, 26) extend transverse to the direction of travel, each mask member being configured for masking only a portion of the maximum exposed image width. There is no mask in the camera configured for masking a portion of the maximum exposed image height. A mechanism (88-94) moves the mask members toward or away from a center of the exposure gate to reduce or increase only a final exposed image width (W.sub.e), without masking the maximum exposed image height. As a result, the final width of the exposed image indicates a required enlargement of exposed image to produce a pseudo telephoto print.

  • Patent number: 5878798
    Abstract: A probe and a valve, which may be used together in a valve assemblage, and a method of using them. The probe has a body and a post having a forward end with a front face and a rearwardly tapering probe post seat. A resilient probe seal has a forward end with a rearwardly tapering probe seal opening, the forward end being movable between an open position and a closed position in which it mates against the probe post seat to close the probe seal opening. The valve has a body with a forward end having a forwardly tapering valve body opening defined by a valve seat. A valve seal in the valve body has a forward end with a forwardly tapering valve seating portion, which is movable between an open position and a closed position in which the seating portion sealingly mates against the valve seat. A resilient means urges the forward end of the valve seal into the closed position.

  • Patent number: 5875040
    Abstract: A method of correcting one or more defect pixels in a defect region of a source image, which image has both the defect pixels and non-defect pixels each of which is represented by at least one defect pixel signal and non-defect pixel signal, respectively. The method comprises:a) searching for edges in a non-defect region of the image adjacent to the defect region by: (i) comparing relative pixel parameters in the non-defect region with a predetermined tolerance to locate a sequence of pixels representing an edge segment the members of which have relative parameters within the tolerance and which sequence is within a predetermined distance of the defect region; and (ii) comparing the length of an edge segment with a minimum length to identify as an edge a segment with at least the minimum length;b) generating at least one pixel signal for the defect region based on the signal of at least one non-defect pixel lying in a direction from the defect pixel which is determined by the direction of an edge.

  • Patent number: 5867322
    Abstract: A method for remote approval of lenticular images and an apparatus which can execute the method. In the method, a centralized hub station receives a series of images. A user then views at a terminal remote from the centralized hub station, a simulated lenticular image using at least some images of the series displayed to simulate viewing an actual lenticular image formed from the images of the series. Following such viewing, an approval is transmitted from the remote terminal to the centralized hub station, for a plurality of the images of the series to be printed as the actual lenticular image. The actual lenticular image is then printed at the hub station based on the approval.
