Abstract: Systems and methods of processing image data using color image sensors are disclosed herein. An example object scanner includes a color image sensor array configured to produce image data representative of an imaging field of view. The example object scanner also includes an image processor. The image process is configured to separate the image data produced by the color image sensor array into two or more channels of image data and, for each of the channels of image data, analyze the respective image data to determine a contrast of the respective image data. The image processor is also configured to select a particular channel of the two or more channels that has the highest contrast; and output the image data corresponding to the particular channel.

Abstract: Methods and devices for driving a laser diode are disclosed herein. An example method includes a boost regulator outputting a maximum boost voltage to drive a laser diode that is configured to output light within a wavelength range of 495 nanometers (nm) to 570 nm. A boost servo may measure a laser voltage, and calculate a voltage difference between the two voltages. The servo may then compare the voltage difference to a drive voltage to determine an excess voltage, and may cause the boost regulator to output an optimum voltage based on the excess voltage. The boost servo may also calculate a low voltage to drive at least one additional component that is electrically coupled to the boost regulator when the laser diode is inactive; and may cause the boost regulator to output the low voltage to power the at least one additional component.
