What is defined as the range of light intensity detectable by a system?

Dynamic range is defined as the range of light intensity detectable by a system, such as a camera or sensor. This term refers to the difference between the darkest and lightest parts of an image that can be captured without losing detail. A higher dynamic range allows for more detail in both shadows and highlights, resulting in a more realistic and visually appealing image.

For instance, in photography, a camera with a high dynamic range can capture a scene with both bright sunlight and deep shadow areas without either becoming completely white or completely black. This capability is crucial in various applications, including film, video production, and any field where accurate representation of light is essential.

Other terms, like intensity modulation, frequency response, and measurement range, refer to different aspects of audio and visual systems but do not specifically address the light intensity detection capabilities of a system. Intensity modulation refers to varying the amplitude of a signal, frequency response pertains to how well a system can reproduce different frequencies, and measurement range relates to the span over which measurements can be accurately taken, which does not specifically denote light intensity.
