A camera system is provided and includes a lens module, a photosensitive module and a fixed frame. The lens module includes a first lens and a lens barrel. The lens barrel is for accommodating the first lens. The photosensitive module includes a photosensitive element and a base. The photosensitive element corresponds to the lens module, and the photosensitive element is disposed on the base. The lens module and the photosensitive module are disposed on the fixed frame, and the lens barrel is made of a material with a thermal expansion coefficient less than 50 (10.sup.6/K @ 20 C.).

Apparatus, system, and computer readable media determine the probability of visual recognition of an image by a subject using electroencephalography (EEG) corresponding to a Visual Evoked Potential (VEP). The apparatus comprises means for presenting a series of visual stimuli corresponding to said image to evoke EEG signals. The visual stimuli of the image are presented in an orientation sequence based on a timing cycle. At least one prism is provided for placement in front of the series of visual stimuli corresponding to said image. The EEG signals evoked in response to said visual stimuli and said prism placed in front of said visual stimuli are recorded and processed by a processor. VEP is generated corresponding to the presence of a shift and thereby provides object statistic reliability of the visual recognition of the image by the subject.

The technology disclosed relates to enhancing the fields of view of one or more cameras of a gesture recognition system for augmenting the three-dimensional (3D) sensory space of the gesture recognition system. The augmented 3D sensory space allows for inclusion of previously uncaptured of regions and points for which gestures can be interpreted i.e. blind spots of the cameras of the gesture recognition system. Some examples of such blind spots include areas underneath the cameras and/or within 20-85 degrees of a tangential axis of the cameras. In particular, the technology disclosed uses a Fresnel prismatic element and/or a triangular prism element to redirect the optical axis of the cameras, giving the cameras fields of view that cover at least 45 to 80 degrees from tangential to the vertical axis of a display screen on which the cameras are mounted.

An image-sensor fixing structure includes an imaging optical system; and an image sensor configured to receive light of an image formed by the imaging optical system. The image sensor has an imaging surface includes an effective region, in which light of an image formed by the imaging optical system is received, and a peripheral region outside the effective region. A body member holding the imaging optical system is fixed to the peripheral region.

A prism apparatus, and a camera and an image display apparatus including the same are disclosed. The prism apparatus includes: a first prism configured to reflect input light toward a first reflected direction, a first actuator configured to change an angle of the first prism about a first rotation axis to change the first reflected direction based on a first control signal, a second prism configured to reflect the light reflected from the first prism toward a second reflected direction, and a second actuator configured to change an angle of the second prism about a second rotation axis to change the second reflected direction based on a second control signal.

A camera and a terminal including the same are disclosed. The camera according to an embodiment of the present invention includes: a first prism apparatus to reflect a first input light input in a first direction to a second direction; a second prism apparatus to reflect a second input light input in a third direction opposite to the first direction to the second direction, and output the reflected second input light to the first prism apparatus; a lens apparatus to receive the first input light from the first prism apparatus or the second input light from the second prism apparatus; and an image sensor configured to generate an image signal based on the first input light or the second input. Accordingly, it is possible to implement a slim camera that can use a single image sensor at the time of front photographing and rear photographing.

The present invention provides an optical collection module, including a bracket, a rotating assembly, a driving assembly for driving the rotating assembly to rotate, and a restoring module. The rotating assembly includes a main body and a prism installed to the main body. The driving assembly includes a magnet and several coils. The main body is rotatably mounted on the bracket. The magnet is installed to one of the bracket and the main body; the coils are installed to the other of the bracket and the main body. The magnet includes two polar faces along the polarization direction; the coils are opposite to one of the polar faces of the magnet. The invention cooperates with the coils through the magnet to make the rotating assembly rotate in multiple directions relative to the mounting plate, thereby the moving range of prism increases accordingly.

Optomechanical tools are disclosed. The optomechanical tools include a body of material having an entrance face, a rake face, a flank face, a rake side face, and a flank side face. The rake side face and the flank side face are connected to the entrance face. The rake side face is connected to the rake face. The flank side face is connected to the flank face. The rake face is connected to the flank face to define a curved cutting edge. The entrance face extends away from the flank side face to define a back-relief angle. The rake face extends away from the rake side face to define a rake angle. The entrance face is configured to direct a light beam toward one or more of the rake face, the flank face, the rake side face, the flank side face, and the curved cutting edge and through one or more of the rake face, the flank face, and the curved cutting edge, causing the light beam to refract onto the workpiece. Systems are also disclosed. Methods for transmitting a light beam through an optomechanical tool are also disclosed.

A camera module includes a housing having an internal space, a reflecting module including a reflecting member on a movable holder movably supported by an inner wall of the housing in the internal space, and a lens module disposed behind the reflecting module in the internal space, and including lenses aligned in an optical axis direction so that light reflected by the reflecting member is incident thereto. The movable holder is configured to move the reflecting member in a first axis direction approximately perpendicular to the optical axis direction and a second axis direction approximately perpendicular to the optical axis direction and the first axis direction with respect to the housing. The lens module includes at least two lens barrels disposed on sidewalls of the housing, linearly movable in approximately the optical axis direction, and including the lenses divided and disposed therein.

The invention provides a prism module and a folded lens. The prism module includes a housing having an accommodation cavity, a prism assembly, a rotation shaft for rotationally connecting the prism assembly and the housing, a driving assembly for driving the prism assembly to rotate around the rotation shaft and a restoring assembly for resetting the prism assembly. The restoring assembly includes a first magnet and a second magnet. The first magnet is fixed on the prism assembly, and the second magnet is fixed on the housing and is set opposite to the first magnet with distance. The prism module of the invention can realize the resetting of the prism assembly, with small space occupation and convenient for assembly.
