IMAGE SENSOR

摘要

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 means (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 colour imaging system may be provided using discrete coloured light sources.
