Abstract
A close-up imaging device may take advantage of the pinhole effect that may be achieved with complementary metal oxide semiconductor imaging arrays. In particular, a high magnification optical lens may be placed at a distance from the imaging array which is less than the focal length of the device. In this way, a relatively compact, low cost imaging device may be used for close-up imaging applications such as fingerprint scanning or text reading.
Claims18
An imaging system comprising:
- a complementary metal oxide semiconductor photosensitive element;
- and
- an image forming optical device spaced from said element by a distance less than the focal length of said optical device.
A method of imaging comprising:
- magnifying the image of an object using an optical device;
- and
