摘要:
An optical reading device of a scanning apparatus includes two light sources and a movable lens. The first light source emits a first light when the optical reading device is operated in a flatbed scanning mode. The second light source emits a second light when the optical reading device is operated in a sheetfed scanning mode. The movable mirror is selected to allow for passing the first light without being obstructed by the movable mirror in the flatbed scanning mode or allow for reflecting the second light coming from the second mirror in the sheetfed scanning mode. Due to the special design, the overall volume of the scanning module is reduced.

A lens front cap module and an image pickup apparatus having a zooming barrel, a focusing barrel and a lens front cap body. Both zooming barrel and focusing barrel are hollow barrel shaped structures. The focusing barrel is installed in the zooming barrel. An abutting portion is formed on an inner wall of the zooming barrel. The lens front cap body comprises a driving plate and a vane module. The driving plate is installed at an end of the zooming barrel and has a central window aperture. A driving pin is axially extended from the driving plate. The vane module is disposed on a side of the zooming barrel for shielding or unshielding the central window aperture. When the abutting portion abuts the driving pin, the driving pin drives the driving plate to rotate, and to drive the vane module to shield the central window aperture.

Dynamic quantization methods and dynamic quantizers for quantizing soft outputs of an equalizer according to the channel condition in order to alleviate the computational load on a soft decision decoder. The dynamic quantizer assigns only a few bits to represent the equalized signals when the channel condition is good, thus reducing computational burden on the soft decision decoder.

An electronic device including a main board, an anti-shake module and a lens module is provided. The lens module is disposed at a first surface or a second surface opposing the first surface of the main board. The anti-shake module includes a flexible printed circuit board (FPCB), an image sensor, a carrier, a first and second guide rod, a first and second moving plate. The image sensor is fixed to the second moving plate and electrically connected with the FPCB. The first and second moving plates are movably disposed at the first and second guide rods respectively. Herein the first moving plate is adapted to move along the axis of first guide rod. The second moving plate is adapted to move together with the first moving plate. And the second moving plate is adapted to move along the axis of second guide rod.

An image capturing device with waterproofing, comprising a main body, a first sensing unit, and a pressure control module. The main body has a containing space for containing an electronic component set. The first sensing unit is disposed at the outside of the main body and used for sensing the pressure where the main body is located to obtain a first pressure value. The pressure control module is disposed in the containing space of the main body and electrically connected to the first sensing unit. By using a second pressure sensing unit to sense the pressure of the containing space, the pressure control module obtains a second pressure value and compares the relative deviation of the first pressure value and the second pressure value through a processing unit to adjust the inner pressure of the image capturing devices.
摘要:
This invention discloses a zoom lens structure and a camera lens. The zoom lens structure comprises a shifting barrel, a zoom-driving ring, a fixed barrel and a focus-driving ring. The shifting barrel has a first guiding protrusion. The zoom-driving ring is arranged at a periphery of the shifting barrel, and having a groove-hole and a first-driving part. The fixed barrel is arranged at a periphery of the zoom-driving ring, and having a first groove. The first guiding protrusion is passed through the groove-hole and inserted into the first groove. The focus-driving ring is coupled to an end of the zoom-driving ring and having a second-driving part at the outer edge thereof. By a driving module driving the first-driving part and the second-driving part at the same time, the zoom-driving ring and the focus-driving ring are rotated forwardly or reversely for zooming or focusing.

A lens barrier device and an image pickup apparatus, comprising a moving barrel, a fixed barrel, a base plate, two vanes and a rotating plate. The base plate has a central window. Two vanes are inserted into the base plate and have a pivot and a control protrusion respectively. The rotating plate has a hollow part and two first grooves. A linking-up body is axially extended from the rotating plate, and has a first guiding protrusion. The moving barrel has a second guiding convex dot. The fixed barrel has a second groove and a third groove. The first guiding protrusion, the second guiding protrusion and the control convex dot are inserted into the first groove, the second groove and the third groove respectively. After the first guiding protrusion is driven, the rotating plate is linked to rotate to open or close the two vanes.
