Abstract: An optical sensing method capable of changing a sensing direction of an optical sensing module is applied to a portable device, which includes a housing, an optical sensing module and an optical diverting mechanism. The optical sensing module is disposed inside the housing. The optical sensing module includes an optical emitter adapted to emit an optical sensing signal out of the housing and an optical receiver adapted to receive an optical modulated signal reflected from an external object. The optical diverting mechanism is adjacent by the optical sensing module. The optical sensing signal is directly projected while the optical sensing signal is not diverted by the optical diverting mechanism, and the optical sensing signal is transmitted to a second direction different from the first direction while the optical sensing signal is diverted by the optical diverting mechanism.

Abstract: A data processing apparatus at a transmitter end has an output interface and a camera controller. The output interface packs a compressed multimedia data into an output bitstream transmitted via a camera interface. The camera controller refers to a compression characteristic of the compressed multimedia data to configure a transmission setting of the output interface over the camera interface. A data processing apparatus at a receiver end has an input interface and a controller. The input interface un-packs an input bitstream received via the camera interface into a compressed multimedia data. The controller configures a reception setting of the input interface over the camera interface in response to a compression characteristic of the compressed multimedia data. In addition, the data processing apparatus at the transmitter end may selectively enable a compression mode by checking the de-compression capability of the data processing apparatus at the receiver end.

Abstract: A data processing apparatus has a first compressor, a second compressor, a first output interface, and a second output interface. The first compressor generates first compressed display data by performing compression upon display data of a first partial region of a frame according to a first compression order. The second compressor generates second compressed display data by performing compression upon display data of a second partial region of the frame according to a second compression order. There is a boundary between the first partial region and the second partial region. In a horizontal direction, the first compression order on one side of the first boundary is opposite to the second compression order on another side of the first boundary. The first and second output interfaces output the first and second compressed display data via a first display port and a second display port of a display interface, respectively.

Abstract: A processor of an apparatus receives sensor data from an inertial measurement unit (IMU). The processor also receives image data. The processor performs a fusion process on the sensor data and the image data to provide a translation output.

Abstract: Methods and apparatuses pertaining to a simulated transparent device may involve capturing a first image of a surrounding of the display with a first camera, as well as capturing a second image of the user with a second camera. The methods and apparatuses may further involve constructing a see-through window of the first image, wherein, when presented on the display, the see-through window substantially matches the surrounding and creates a visual effect with which at least a portion of the display is substantially transparent to the user. The methods and apparatuses may further involve presenting the see-through window on the display. The constructing of the see-through window may involve computing a set of cropping parameters, a set of deforming parameters, or a combination of both, based on a spatial relationship among the surrounding, the display, and the user.
