visual noise

Visual noise refers to random or unwanted visual artifacts present in an image or video, often appearing as static, grain, or flickering spots. It results from factors such as low light conditions, high ISO settings in cameras, or digital compression, which introduce irregularities that reduce image clarity. Essentially, it’s like the static you see on a fuzzy TV screen—disrupting the smooth, clear visual experience. While some noise can add a stylistic effect, excessive noise diminishes image quality and detail, making it harder to discern fine features or details in the visual content.
