Final answer:A digitizer in image processing converts analog input into digital output, enabling the use of analog data in digital systems. In the given options, the correct task performed by a digitizer in image processing is option D: Produces digital output, from analog input.Explanation:A digitizer in image processing has a very specific role. Its task is to convert analog signals, such as those from a traditional camera or sensor, into digital output. This process of conversion is essential in many fields, including mechatronics, where sensors may capture analog data that must be used by digital systems. For instance, consider a mechatronics-based steering mechanism in an auto-guided tractor that uses a linear potentiometer to estimate the steering angle. The potentiometer outputs an analog signal in volts corresponding to the steering angle, which must then be converted into a digital form to be processable by the tractor's computer system.In the broader scope, digitization has become prevalent in our everyday lives. From digital cameras to mobile phones, analog signals are converted to digital ones for processing, storage, and transmission. The role of digitizers is critical in enabling the full digitisation of images and sounds that can then be edited, shared, and archived in digital format.Therefore, the correct option for the role of a digitizer in image processing is D. Produces digital output, from analog input....
