1. Vision refers to the visual system or visual capabilities. Explanation: The term "vision" is widely used to describe various systems and functions related to vision. In the field of technology, particularly in computer vision and image processing, "vision" typically refers to the use of computers to simulate the human visual system, enabling functions such as image recognition and object detection. Moreover, in everyday contexts, when discussing a person's eyesight or visual experience, the term "vision" is also employed. It encompasses a complex series of processes from light perception to image interpretation. In multiple disciplines including computer science, physics, biology, and more, there is research and application involving the visual system. Hence, when discussing technologies or concepts related to vision, we commonly use the term "vision" rather than referencing the specific underlying system or function.
