Abstract

See full text

The present invention relates to a micro-optical pointing device suitable for mobile terminals such as a cellular phone and PDA. A disclosed pointing device includes a light source emitting light rays to a subject; a contact member comprising a lattice type or perceivable pattern, which reflects an image of the moving subject; and an automatic transfer device restoring the contact member moved by a finger. The pointing device may further include a flip chip containing an image sensor, which converts the acquired image into an electronic signal, and a circuit for signal processing. The pointing device may include an integrated optical structure comprising a condensing lens, a specular surface, a light output part, and an image-formation lens. The pointing device may include a light guide structure that a parallel light prism lens, an image-formation lens, and a mask for blocking disturbance ray are formed into a single part.
