What is image acquisition?
Answer
Image acquisition is the process of capturing a physical image or scene and converting it into a digital format that a computer can process. It typically involves a sensor, such as a camera or scanner, which captures light or other radiation and transforms it into electrical signals, followed by an analog-to-digital converter (ADC) to create a digital representation.
