Abstract

An image sensor comprises an image capturing device 10 and a lens arrangement 20, 30, 40, positioned between an area to be imaged and the image capturing device 10. The lens arrangement includes at least one array 40 of spaced lens elements 42 for transmitting light from a portion of the area to be imaged to a portion of the device 10. Light emitting apparatus 46, for example electroluminescent strips, are disposed in or over the spacing between the lens elements 42. This provides a compact optical focusing and illumination system. A color imaging system may be provided using discrete colored light sources.
