Abstract
Abstract The method of checking the off-alignment and identifying the relative position of lenses in a multi-lens, 3-D camera and calibrating the coordinates of the positions of the components (i.e., 2-D view, projecting lens or print material easel) of a printing system. The method for the automatic correlation of 2-D views for the composing of high quality 3-D photographs by taking the first set of 2-D photographs on the film of a target at a predetermined distance. The target images are projected onto a group of CCD sensor arrays placed at the image plane of the printer with each individual sensor of the CCD array precalibrated, and a computer on the printer is programmed to recognize the location of the target images on the CCD array and to control the motors on the printer to adjust the position of the enlarging lens, the easel or the 2-D view in order to correlate the 2-D views for the aligning of the photographed image on the print material at the time of composing of the 3-D photograph.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
152 words
A method for compensating for any off alignment of the lenses in a 3-D camera in the printing of 2-D views which comprises: a. Exposing the first set of 2-D views of the film in the camera to a target at a predetermined distance; b. Projecting the first set of 2-D views in a 3-D printer with an image processor to determine the x and y axis of each of the images in the printing plane of the printer; and c. Entering the x and y coordinates of each of the projected images into a microprocessor programmed to automatically adjust the position of each subsequent 2-D view in each set of 2-D views to the desired position by moving means in order to compensate for any off alignment of the camera lens on the x and y axis in printing each of the views in accordance with the directions from the microprocessor.
Claim 2
Independent Claim
152 words
A method for compensating for any off alignment of the lenses in a 3-D camera in the printing of 2-D views which comprises: a. Exposing the first set of 2-D views of the film in the camera to a target at a predetermined distance; b. Projecting the first set of 2-D views in a 3-D printer with an image processor to determine the x and y axis of each of the images in the printing plane of the printer; and c. Entering the x and y coordinates of each of the projected images into a microprocessor programmed to automatically adjust the position of each subsequent 2-D view in each set of 2-D views to the desired position by moving means in order to compensate for any off alignment of the camera lens on the x and y axis in printing each of the views in accordance with the directions from the microprocessor.
Claim 3
Dependent Claim
84 words
The method of claim 1 in which the determination of the x and y coordinates of the target of each of the images of the first set of 2-D negative views is determined visually in the printing plane, and these coordinates are entered into the microprocessor programmed to automatically adjust the position of each subsequent 2-D view and moving means in the printing process in order to bring each 2-D view into proper alignment along the x and y coordinates before printing such view.
Claim 4
Dependent Claim
73 words
The process of claim 1 in which the determination of the x and y coordinates of the target of each of the images of the first set of views is determined by CCD sensors which are linked to a microprocessor programmed to automatically adjust the position of each subsequent 2-D view in each set of 2-D views by moving means in the printing process into proper position before printing of each 2-D view.
Claim 5
Dependent Claim
19 words
The method of claim 3 in which the CCD sensors are located in the printing plane of the printer.
Claim 6
Dependent Claim
31 words
The method of claim 3 in which the microprocessor is linked to a motor and drive which moves a printing easel into proper position for the printing of each 2-D view.
Claim 7
Dependent Claim
45 words
The method of claim 3 in which the microprocessor is linked to a motor and drive which moves the projecting lens into proper position for the printing of each 2-D view in order to correct any off-alignment of the camera lens in a 3-D camera.
Claim 8
Dependent Claim
159 words
The method of claim 5 in which the microprocessor is programmed to automatically move the printing easel into proper position for the printing of each 2-D view in accordance with the following formulae: A. formula for determining the amount of offset needed in the X direction. ##EQU6## B. formula for determining the amount of offset needed in the Y direction. ##EQU7## where X is the amount of adjustment required in the X direction to compensate for the off-alignment of the camera lens; y is the amount of adjustment required in the y direction to compensate for the off-alignment of the camera lens; Tx is the distance of off-alignment of the camera lens in the X direction; Ty is the distance of off alignment of the camera lens in the y direction; D is the distance from the camera to the photographed object; F is the Back Focal Distance of the camera lens; and R is the enlargement ratio (V/U).
Claim 9
Dependent Claim
154 words
The method of claim 6 in which the microprocessor is programmed to automatically adjust the position of each 2-D negative in the negative carrier into proper position for printing utilizing the following formulae: C. amount of offset required in the x direction ##EQU8## D. amount of offset required in the y direction ##EQU9## where Sx is the distance the 2-D negative view is to be moved to compensate for the off-alignment of the camera lens in the x direction; Sy is the distance the 2-D negative view is to be moved to compensate for the off-alignment of the camera lens in the y direction; Tx is the distance of off-alignment of the camera in the X direction; Ty is the distance of off alignment of the camera lens in the y direction; D is the distance from the camera to the photographed object; and F is the Back Focal Distance of the camera lens.
