摘要:
A method of recording a reference calibration target on an APS format photographic element having a reserved area for use by photofinishing apparatus, and a perforation located relative to the reserved area, includes the steps of: generating a reference calibration target having a width no greater than 30.2 mm and a height no greater than 16.7 mm; locating the reserved area of the photographic element relative to the perforation; and recording the reference calibration target within the reserved area.

A method of calibrating digital images having pixels with pixel values includes the steps of: exposing a photographic element to form a latent image of a reference calibration target including a plurality of reference calibration patches; exposing the photographic element to form a latent image of a scene; processing the photographic element to form developed images from the latent images on the photographic element; scanning the developed images to produce digital images; measuring the pixel values of the digital image of the reference calibration target to produce a measured value for each of the reference calibration patches; obtaining an aim value and adjustment data corresponding to each reference calibration patch; generating image calibration corrections using the measured values, the aim values, and the adjustment data; and applying the image calibration corrections to the digital image of the scene.
摘要:
Reference calibration patches produced by a sequence of exposures on a photographic element, the photographic element exhibiting linear defects in a predominant direction, are arranged in a two dimensional array and exposures are assigned to the reference calibration patches in the array such that nearest neighbors in the predominant direction are not nearest neighbors in the exposure sequence, whereby the effects of a linear defect are reduced; and the maximum number of steps in the exposure sequence between a reference calibration patch and that of its nearest neighbors in any direction is less than a predetermined number, whereby the effects of flare are reduced.

A prerecorded magnetic master web (54) and an unrecorded magnetic slave web (14), such as a photographic film having a magnetic coating, are brought into intimate contact for anhysteretic recording by wrapping the moving master web partially around a small diameter gimballed roller (66) positioned in close proximity to a rotating transfer drum (36); wrapping the moving slave web partially around a larger idler roller (34) positioned in close proximity to both the gimballed roller and the transfer drum; wrapping the slave web partially around the transfer drum with the master web wrapped outside the slave web; and evacuating a chamber or volume (68) formed among the webs, rollers and drum, to remove air from between the webs and cause them to converge into intimate contact at a nip upstream of a signal transfer zone in which a magnetic head (70) applies a decaying magnetic field to cause anhysteretic transfer from the master web to the slave web.

A two part clamshell web cassette is provided with a central recess for receiving a web roll core. The core and cassette half shells have mating surfaces which form a labyrinth light seal when the cassette is closed and which prevent rotation of the core during handling of the cassette to provide a core brake. Surfaces on the cassette parts clamp the web tail of a partially dispensed web roll when the cassette is closed. The core brake and web clamping surfaces facilitate transport of the cassette without loss of intra-roll web tension. The cassette is provided with a latch for retaining the cassette half shells in a closed light sealed condition. A frangible covering over a latch release means indicates when broken that the cassette may have been opened prematurely. The cassette further includes a web end retaining means which retains the web end portion to the underlying convolution. The cassette further includes an orientation of light blocking surfaces on each half shell which permits the half shells to be identically molded and then rotated 180 degrees during assembly to cause the light blocking surfaces to mate.

A ported vacuum drum (20, 56-98) is provided on its exterior cylindrical surface (22) with a master layer (24) of magnetic recording medium in position to contact a slave layer (14) of magnetic recording medium provided on one side and along at least one edge of a web (10); so that, vacuum applied (74-82) between the cylindrical surface and the web at locations (88-94) spaced from the zone of contact (98) between the recording media will hold the slave layer on the web securely in contact with the master layer on the drum as the drum rotates, thereby permitting anhysteretic recording from the master layer to the slave layer. A method of anhysteretically recording is taught.

The core and cassette half shells have mating surfaces which form a labyrinth light seal when the cassette is closed and which prevent rotation of the core during handling of the cassette to provide a core brake.

In a bale case (20) of an agricultural baler, a reciprocating plunger (71) is connected by a connecting rod assembly (90) and a wrist pin (92) to a driving crankshaft (74). A tension adjusting system (60) is provided for adjusting the dimensions of a bale case (20). The tension adjusting system (60) is responsive to a signal produced by sensors which sense stress when a compactive force is applied by the plunger (71) to crop material in the bale case (20). In one embodiment shear stress sensors (124, 126, 128, and 130) are mounted in annular recesses (120, 122) on the exterior of a wrist pin (92) to sense upon compaction the shear stress experienced by the wrist pin (92) in shear planes (160A, 160B). In another embodiment shear stress sensors (170, 171, 172, and 173) are mounted on an interior surface (174) of a wrist pin (90') to sense the shear stress experienced by the wrist pin (92') in shear planes (176, 177). In an another embodiment, bending stress sensors (182, 183, 184 and 185) are mounted on chordal flat portions (180 and 181) of a wrist pin (92") to sense upon compaction the bending stress experienced by the wrist pin (92") in a bending plane. In another embodiment, a load cell (190) with stress sensors (194, 195) mounted thereon is mounted between a connecting rod plate (98) and a connecting rod bearing housing (102).

Apparatus for pneumatically clamping and magnetically biasing magnetic media during anhysteretic transfer comprises a housing (64, 74, 76, 80, 82, 88, 90, 96, 98) which encloses a pair of pneumatic plenums (112) connected to a source of high pressure air (70, 72, 73) and a pair of arrays (106) of biasing magnets (108); so that, air from the plenums flows between the magnets and bands (57) at the edges of the media to provide intimate contact of the media during anhysteretic transfer.
