Title: Subminiature aspherical plastic lens system for a camera of a camera phone
Inventor: PARK WON-HEE
IPC: G02B3/02
Filed: 2003-04-28
Granted: 2004-10-11
Abstract: A subminiature lens system for a camera of a camera phone is disclosed. An iris for adjusting an intensity of a light, a first lens, and a second lens are disposed in sequence from an object side to an image side. Preferably, an infrared cut-off filter may be disposed between the second lens and an image surface. The first lens and the second lens are aspherical plastic lenses and the first lens has a meniscus shape, in which a surface facing the object side is convex and the other surface is concave. Further, in the second lens, a surface facing the object side is concave and the other surface is nearly flat, so that a diffused reflection which can occur on a sensor surface can be reduced. The first lens and the second lens are aspherical plastic lenses, since they are produced by injection moldings, they can not only be produced in large quantities, but also can be subminiaturized and ultralight. Further, since the production process is simple, the cost of production can be reduced. The iris not only minimizes an incidence angle of a principal ray being incident to the image surface by being positioned at a farther distance from the image surface, but also prevents a surface of the first lens from being damaged. The lens system is the most suitable for 1/4 inch, 1/5 inch and 1/7 inch image sensor having 300,000 pixels.

The drivers (12 to 14), of which one end terminals are respectively connected to the terminals in connection with the other terminals of luminescent element series, are turned on or off according to the command signal (S1 to S3), and will make the current flow to light the luminescent element corresponding to that is on. The selecting circuit (18) selects the lowest voltage from those applied to these drivers, as a detected voltage. The control circuit (11) automatically controls the output voltage of power circuit to make the detected voltage be a low voltage (i.e., reference voltage) at which constant current driver can perform constant current operation. Thus, the luminescent elements may light completely and the lose of drivers can be reduced.
