20120162072 | Optical Pointing Device - An optical pointing device including a light source, an optical transfer assembly, a light beam splitter, and an image sensor is provided. The light source provides an illumination light beam. The optical transfer assembly concentrates the illumination light beam. The light beam splitter is disposed on a transmission path of the illumination light beam for splitting the illumination light beam into a first light beam and a second light beam. The image sensor is capable of sensing the first and the second light beams. When the optical pointing device is used on a reflective surface, the first light beam is reflected to the lens by the reflective surface and then is received by the image sensor; when the optical pointing device is used on a transparent body above the reflective surface, the second light beam would be received by the image sensor. | 06-28-2012 |
20130241884 | OPTICAL TOUCH APPARATUS CAPABLE OF DETECTING DISPLACEMENT AND OPTICAL TOUCH METHOD THEREOF - An optical touch apparatus includes a first light source, a second light source, a light guide device, a light reflecting device and an image sensing module. The first light source emits first light beam which travels within the light guide device and is reflective by an object close to or in contact with a surface of the light guide device to become a first image light beam. The first image light beam is reflected by a light reflecting device. The image sensing module receives the first image light beam. The second light source emits a second light beam, wherein when the optical touch apparatus moves on a working surface, the second light beam is reflective by the working surface to form a second image light beam which is received by the same image sensing module. | 09-19-2013 |
20140084134 | MINIATURIZED OPTICAL SYSTEM, LIGHT SOURCE MODULE AND PORTABLE ELECTRONIC DEVICE - There is provided a miniaturized optical system including a protection cover, a light source, an image sensor and at least one interference film. The protection cover has a first surface and a second surface. The light source and the image sensor are disposed opposite to the first surface of the protection cover. The interference film is disposed between the light source and the protection cover to allow the light source to form a predetermined light shape in front of the second surface of the protection cover and/or disposed between the image sensor and the protection cover to allow the image sensor to receive light of a predetermined range in front of the second surface of the protection cover. | 03-27-2014 |
20140209783 | OPTICAL POINTING DEVICE AND DETECTING METHOD THEREOF - An optical pointing device for detecting the direction of the user's finger is provided. The optical pointing device comprises a cover, a light source and a sensor. The cover comprises a press portion with a first surface and a second surface opposite the first surface, as well as a side wall extending downwards from the periphery of the second surface. The light source projects a main beam onto the press portion of the cover. The main beam then forms a first beam passing through the press portion and a second beam reflected by the second surface. The sensor is adapted to receive the second beam reflected by the second surface, and detect the second beam by an algorithm to output the first displacement position. In addition, the light source and the sensor are covered by the cover, while the side wall is a flexible side wall. | 07-31-2014 |
