Abstract: A semiconductor device comprises a first semiconductor structure, a second semiconductor structure located on the first semiconductor structure, and an active layer located between the first semiconductor structure and the second semiconductor structure. The first semiconductor structure has a first conductivity type, and includes a plurality of first layers and a plurality of second layers alternately stacked. The second semiconductor structure has a second conductivity type opposite to the first conductivity type. The plurality of first layers and the plurality of second layers include indium and phosphorus, and the plurality of first layers and the plurality of second layers respectively have a first indium atomic percentage and a second indium atomic percentage. The second indium atomic percentage is different from the first indium atomic percentage.

Abstract: A method, an apparatus and a system for displaying an image of a vehicle blind spot are provided. The apparatus is coupled to at least one external camera disposed outside the vehicle, at least one internal camera disposed inside the vehicle with a lens facing towards a driver, and at least one display disposed inside the vehicle. The method comprises capturing an image of the external environment of the vehicle by the external camera as an external image, capturing an image including the driver by the internal camera as an internal image, recognizing a face of the driver and a displacement of the face in the internal image, and adjusting a position of an ROI in the external image according to the recognized displacement, to display an image of the ROI on the display corresponding to the external camera. The displayed image of the external of the vehicle may be adjusted according to the posture or the angle of view of the driver, to have the image of the current blind spot by the driver shown correctly.
