Abstract
Corrective data for left and right sensor arrays of a range-finding optical system is stored as a difference between a maximum sensor output and a correction function. The stored data is taken while imaging a blank white target area. In use, the corrective data is added to outputs of each sensor. This technique reduces the number of storage bits required per sensor, and permits improved correlation. The reduction in storage bits permits a reduction in chip size. Differences in sensitivities of right and left sensor arrays are not corrected independently. Instead, the two sets of corrective data enhance the similarity between counted value rows from the right and left sensor arrays.
