Claim One:
1. A method of determining a pixel spread for use in creating an autostereoscopic image, the method comprising the steps of: determining angle A1 based on the following formula: A1=M/N−1, where M is a value between 0° and 180° and N is the number of different positions for the image acquisition devices; determining an arbitrary Z measurement; determining an arbitrary starting estimate of the pixel spread; calculating a Z axis position of a testing artifact based on N, the current estimate of the pixel spread, the arbitrary Z measurement, and angle A1; determining the N different positions of one or more image acquisition devices based on N, angle A1 and the current calculated Z axis position of the testing artifact; creating a test autostereoscopic image of a testing artifact positioned at the current calculated Z axis position with one or more image acquisition devices at the determined N different positions; judging whether the current test autostereoscopic image resolved properly, wherein: if the current test autostereoscopic image resolved properly, the current estimate of the pixel spread is increased, and the process repeats the steps of calculating a Z axis position, determining the N different positions, creating a test autostereoscopic image, and judging the current autostereoscopic image; if the current test autostereoscopic image did not resolve properly, recollecting whether the previous autostereoscopic image resolved properly, and further wherein if the previous autostereoscopic image resolved properly, ending the method and relying on the associated previous estimate of the pixel spread as the final pixel spread, but if the previous autostereoscopic image did no resolve properly, the current estimate of the pixel spread is decreased, and the process repeats the steps of calculating a Z axis position, determining the N different positions, creating a test autostereoscopic image, and judging the current autostereoscopic image; and conveying to a user the final pixel spread from the judging step.
