Abstract: An image processing apparatus comprises a distance measurement section for measuring a distance from the section to a subject for each pixel on the basis of a plurality of images photographed at different visual point positions. A setting section sets a range of the distance in which an obstacle is present. An image formation section executes image processing of replacing a first image signal relating to an obstructed region included in the range of the distance with a second image signal different from the first image signal on the basis of an output from the distance measurement section.
Abstract: A line of sight adjustment device (LSAD) employs a simple yet robust structure and method to adjust the line of sight (or boresight) of a telescope, clip-on night sight, night vision sight, day scope, or other optical sighting device. In one embodiment, the LSAD includes a single optical element adjusted to change the apparent viewing angle to a target viewed through the device without degrading the optical quality of the image.
Abstract: A range finding device and method for determining the distance between a merged submarine and a target above the surface having a first and second periscopes mounted on a submarine with a known separation. These periscopes are rotatable and extensible above the surface and can determine the bearing from each of the periscopes to the target. A computer receives the bearings from the first and second periscopes and uses the bearings with the known preset distance between the periscopes to calculate the distance between the submarine and the target.

Abstract: A gun sight positioning mechanism (22) disclosed includes a parallelogram linkage for moving a gun sight positioning shaft angularly with a trunnion shaft (32) on which a gun is supported and has a slip clutch (44) that connects the linkage to one of the shafts so that the sight can be aimed downwardly at the target area while the gun remains aimed upwardly along the projectile path. Preferably, the slip clutch connects the linkage to the gun sight positioning shaft and includes a stop (56) that allows the sight to be aimed upwardly back into alignment with the gun after viewing the impact. First and second links (46,52) of the linkage are respectively connected to the trunnion and sight positioning shafts and interconnected by a connecting link (54) whose length is adjustable to insure the proper angular movement of each shaft with the other.
