摘要： Disclosed systems and methods generate a sequence of images using a data reader having an imager exposed to multiple fields of view that are alternately illuminated to coincide with exposure periods forming an image capture rate. In one configuration, a first illumination source illuminates a first field of view of the data reader with a first series of illumination pulses at a first pulse repetition rate. The imager captures in an alternating manner a first set of images of the first field of view and a second set of images of a second field of view. The first pulse repetition rate and the image capture rate are set such that the imager captures the first set of images at approximately the same time as the first illumination source illuminates the first field of view with an illumination pulse.

摘要： A data reader preferably includes an imaging device that operates on a rolling reset basis to capture images of a moving target. Images of moving targets are preferably analyzed to determine the ambient light intensity, and a processor in the data reader preferably adjusts operation of the imager and of a light source based on the intensity of the ambient light. Other data readers may use an imager with a mechanical shutter that is designed for rapid, frequent operation.

摘要： Methods and systems are disclosed for producing color-image data representative of a color optical code or other color objects, particularly with a monochrome imager. Monochrome image-sensor data is produced by receiving a sequence of colored light emitted by an artificial light source and reflected from the color object. The sequence of colored light may be a red, green, and blue sequence of colored light emitting diode lights according to some embodiments. The monochrome imager produces the monochrome image-sensor data based at least in part on the portion of the reflected sequence of colored light. The monochrome image-sensor data is processed to produce color-image data representing the color optical code.
