Abstract:
An optoelectronic device for acquiring machine-readable symbols, comprising:a two-dimensional sensor having a plurality of pixels each transmitting electrical signals representing a quantity of light incident on the respective pixel, the pixels arranged in a plurality of rows, the pixels in each of the rows extending in a scanning direction, and the plurality of rows arranged in a direction perpendicular to the scanning direction with respect to one another; and a scanning control circuit coupled to the two-dimensional sensor to selectively receive electrical signals from successive sets of the pixels along the rows in the scanning direction in at least a first and a second successive pass along the rows, where the sets of the pixels extend across at least one row in a direction perpendicular to the scanning direction, and each set of the pixels has a first height in the direction perpendicular to the scanning direction during the first pass and a second height in the direction perpendicular to the scanning direction during the second successive pass, the second height different from the first height.
