In addition to single- chip digital cameras, there are also dreichip digital cameras. In this type of camera, the incident light is split into the primary colors red, green and blue by means of a prism and fed to three image sensors.
Dreichip digital cameras have better color fidelity than single-chip digital cameras and higher light sensitivity and resolution. The higher cost and precision of optical alignment of the sensors to the prism is expressed in a higher price. Dreichip digital cameras can be used for color measurements.
