Cameras and projectors are critical components in modern digital imaging and display systems. Cameras capture visual data through optical sensors, while projectors display digital content onto physical surfaces. These devices play essential roles in communication, education, entertainment, industrial automation, and medical diagnostics, enabling visual data acquisition and presentation across diverse applications.
