Abstract
An optical code reader includes a color image sensor array having first and second sets of pixels arranged along multiple parallel axes of a first axes group and multiple parallel axes of a second axes group transverse to the first axes group. The pixels of the first set produce data representing sensed light intensity values. In one configuration, the optical code reader includes a single-axis interpolator to produce interpolated intensity values that correspond to selected locations of pixels of the second set. The single-axis interpolator is operable to produce an interpolated intensity value for a selected location by using only intensity values sensed by pixels of the first set that share an axis of the first axes group with the selected location.
