Which of the following statements is true regarding sensors?

The statement that individual pixels capture light and affect exposure is true because each pixel in an imaging sensor is responsible for capturing a portion of the incoming light. The amount of light captured by each pixel directly influences the exposure of the image; more light leads to a brighter image, while less light results in a darker image. Additionally, the arrangement and size of these pixels play a crucial role in determining the sensor's performance, especially in low-light conditions, since larger pixels can gather more light than smaller ones, enhancing image quality.

The other statements present oversimplifications or inaccuracies regarding sensors. For example, while higher pixel counts can contribute to better image quality, it is not always the case—factors such as sensor size and architecture also play significant roles. Similarly, CCDs do not universally outperform all other sensor types; advancements in technologies like CMOS can sometimes offer comparable or superior performance for specific applications. Lastly, not all sensors adhere to the same resolution standards, as resolution can vary widely among different types and models of sensors depending on their intended use and design constraints.
